      On-demand conductivity for graphene nanoribbons: Physicists from Uzbekistan +Germany have devised a theoretical model to tune the conductivity of graphene zigzag nanoribbons, using ultra-short pulses - NTN/S/EPJ, HEIDELBERG/NEW YORK - Nov 10, 2014

      "The authors' focus is on the transport in graphene nanoribbons driven by laser pulses, which were chosen for their ability to apply periodic kicks to the system. Babajanov and colleagues relied on driven quantum systems and quantum chaos theories to study transport characteristics within the nanoribbon. For a single kicking period, they obtained the exact solution of a mathematical equation, called the time-dependent Dirac equation. Then, by iterating this solution they were able to numerically and precisely compute the arbitrary characteristics of time-dependent quantum transport of electrons within the material.


      They found that applying external driving force leads to enhancement of electronic transitions within what are referred to as valence and conduction bands. This study thus demonstrates that such transitions allow a dramatic increase in conductivity within a short time, making it possible to tune the electronic properties using short external pulses.

      The next stage could be extending the test to the case of a time-dependent magnetic field, to strain-induced pseudo-magnetic fields, or to external monochromatic fields. Ultimately, this could lead to useful applications such as ultrafast electronic switches.


      Abstract:

      Physicists have, for the first time, explored in detail the time evolution of the conductivity, as well as other quantum-level electron transport characteristics, of a graphene device subjected to periodic ultra-short pulses. To date, the majority of graphene studies have considered the dependency of transport properties on the characteristics of the external pulses, such as field strength, period or frequency. The new findings have now been published in EPJ B by Doniyor Babajanov from the Turin Polytechnic University in Tashkent, Uzbekistan, and colleagues. These results may help to develop graphene-based electronic devices that only become conductors when an external ultra-short pulse is applied, and are otherwise insulators. "

      Graphene-based scanner to reveal hidden aspects of artwork, A group of European researchers are developing a 'next generation graphene based scanner', which will allow hitherto unknown aspects of works of art +other historic objects to be revealed.

      "A group of European researchers are developing a next generation graphene based scanner which will allow hitherto unknown aspects of works of art and other historic objects to be revealed. The equipment will enable the viewing of hidden images on canvases and unveil what is hidden inside three dimensional objects sealed centuries ago.



      - Testing the augmented reality based application in a real scenario. -


      As well as showing sketches or previous paintings that have remained hidden beneath a particular art work, “the scanner will allow us to see preliminary drawings or identify overpaintings”. So explains Javier Gutiérrez, researcher at Treelogic and co-ordinator of Insidde, the Seventh Framework Programme – European Union funded project within which this work falls, and in which eight organisations from five European countries are participating.

      The scanner allows the way in which the brushes have been applied to be observed, information which is opening up new fields of work for the scientists of Insidde: “The scanner may show details on how a painting was made that are of great art-historical value, because they tell us more about how the painter worked; these details are also extremely helpful for conservators when preparing for the restoration of paintings”, notes Laurens van der Maaten from Delft University of Technology.


      An unexpected result

      Although the scanner is still in its trial and calibration phase, the researchers have already managed to use it to identify some of the materials found in specific works of art. This is a result that experts from the participating museums have been very positive about. In the words of Marta Flórez (Museum of Fine Arts of Asturias), “we didn’t expect to get this type of information, but with the prototype we have been able to clearly distinguish between some pigments, which in some cases will avoid having to puncture the painting in order to find out what materials the artist used”.

      Besides inspecting paintings, which have a planar surface, the researchers are testing and adjusting the scanner in order to be able to generate images of sealed three-dimensional objects. For this, a structured-light scanner will be combined with the terahertz scanner.



      - (a) Still life. (b) Reproduction used for test and validation purposes. (c) Samples to be analysed with the terahertz scanner consisting of multiple pigments found in the original painting. -


      Geert Willems, Director R&D of 4DDynamics explains the benefit: “By reconstructing the 3D shape of the objects, we can help guide the terahertz scanner to the optimal positions around the curved shape of the objects, while making sure the scanner does not come in actual contact with the artwork”.

      In the near future they will be scanning various Bulgarian pots from the 3rd century which were sealed when they were found, and whose contents are unknown. Reneta Karamanova, restorer at the Regional Museum of History Stara Zagora, adds "Another valuable application of the scanner to archaeologists and restorers is its use to identify painted, carved or embossed decoration of pottery on which surface there are deposits of dust or limestone. The ascertainment of the condition of the ceramic surface by terahertz analysis would prevent the damage that can be caused to the vessel by manual cleaning of the deposits."


      More frequencies, more information

      The graphene scanner is seen “as a new instrument which in no way damages the materials being studied and which will extend the investigated spectral region, and make more accessible the use of THz imaging analysis in the world of art” comment Raffaella Fontana and Marco Barucci from CNR-INO, who participate in the development of the focusing system. Mounted on what is referred to as the “XYZ table”, which measures 1.50 x 1.50 metres and is 1.20 metres high, the scanner comprises multiple heads which incorporate graphene emitters and receptors and can move three-dimensionally across the 2 square metre work area.

      With regard to whether this scanner could replace the other methods that exist for obtaining hidden images in works of art such as scanners using x-rays, infra-red or ultraviolet radiation, the researchers at the University of Oviedo, in charge of the system, are quite clear: “Each frequency range has a different capability in terms of penetrating the different layers of a piece of work, so the information that is recovered with each technique is complementary to the others”, explains Samuel Ver Hoeye, technical coordinator of the project.



      - (a) Ceramic from the III century. (b) Setup for 3D acquisition with a structured light scanner. (c) 3D model resulting from raw data before post-processing. -


      Whyyyyy graphene?

      Considered one of the materials of the future, graphene is formed by carbon atoms in a single layer only one atom thick. One of its many peculiarities is that, when submitted to electromagnetic waves, it behaves in a non-linear way. In other words, “It functions like a kind of frequency multiplier. If we make a wave of a particular frequency impinge on graphene, the graphene has the ability to emit another, higher, frequency”, agree David Gómez and Nuria Campos from ITMA Materials Technology.

      This property of graphene is allowing scientists to emit, in the terahertz band, a band of frequencies which until now have mostly been achieved in experimental settings and which are lower than infra-red but higher than the frequencies used by mobile phones and satellite communications. For this reason, “beginning to use it means filling a niche that exists between the frequency bands of other technologies that have already been developed”, acknowledges Javier Gutiérrez.


      Sharing results

      Beyond disseminating the results of their work in specialised international conferences, one of the priorities of the Insidde project is to ensure that the results also reach the general public, and as such the researchers will be making the images discovered by the graphene scanner publicly available. In this vein, the consortium is developing various means by which to popularise this new knowledge, for example through an augmented reality app for mobile phones which can be used in museums and art galleries. And, without having to leave home, the images can be seen on the internet through the open network Europeana.


      Members of the Insidde consortium

      Led by Treelogic, the following seven organisations from five European countries are participating in the Insidde project (Integration of technological solutions for imaging detection and digitisation of hidden elements in artworks): from Spain, ITMA Materials Technology, the University of Oviedo and the Museum of Fine Arts of Asturias; from The Netherlands, Delft University of Technology; from Italy the Istituto Nazionale di Ottica; from Bulgaria, the Regional Museum of History of Stara Zagora, and from Belgium the company 4DDynamics.

      Free online course on graphene will be available worldwide
      www.nanowerk.com/nanotechnology-news/newsid=38190.php

      "Starting in 2015, Chalmers University of Technology in Sweden will be a global disseminator of knowledge. The beginning of the year will mark the start of ChalmersX – the venture of Chalmers moocs on the platform edx.org.


      Chalmers announces its membership in edx at the ongoing conference Edx Global Forum in Boston. Edx is the platform where Chalmers' moocs will be accessible. Universities such as MIT, Harvard, UC Berkeley, the University of Tokyo and many more offer their moocs on the same platform.

      “This is a new and different way for us to take on the role of knowledge disseminator in our society“, says Maria Knutson Wedel, vice president for undergraduate and master’s education at Chalmers.

      With a computer and an Internet connection, course participants all over the world can watch video lectures, take part in discussions, do assignments and take exams.
      “Previously, we have primarily shared knowledge on a local and national level. The technology today enables global knowledge sharing – we can reach people who need the knowledge in question no matter where they are located in the world,“ says Maria Knutson Wedel.


      The first ChalmersX mooc will be an introduction to the super-material graphene: Introduction to Graphene Science and Technology. The subject is at the forefront of research, and EU's biggest research initiative ever – Graphene Flagship – is based at Chalmers.

      The course is led by graphene researcher Jie Sun. He took the initiative to the mooc as he saw the need of large-scale education about graphene.

      I hope to give the participants of the course basic knowledge of graphene. At the end of the course, an engineer should be able to determine if graphene is suitable for the company's products, and a student should be able to decide if the subject is of interest for continued studies”, says Jie Sun.


      Moocs are a growing trend in higher education. There is a great deal of interest in the courses – each one typically attracts tens of thousands of participants.
      Maria Knutson Wedel believes that moocs can be very useful as supplementary or continuing professional development for people who are already part of working life. She does not believe that the courses can completely replace a traditional campus education, however. Campus education are closely connected and designed to correspond to the expectations from industry, for example. This type of education also results in a degree and a title, something which companies consider when hiring.

      “However, this probably depends in part on traditional thinking on the part of the people who do the hiring at companies. In the future, we may reach a point that knowledge, regardless of how it has been obtained, becomes more important than certificates and grades,“ says Maria Knutson Wedel.

      The ChalmersX moocs will be specially adapted to their context – the recordings will not consist of traditional 45-minute lectures. The teachers who have developed the course have carefully analysed the concepts they want participants to come away with after the course. The content is then boiled down to short video clips of 5-7 minutes each.

      The next mooc in line after the course on graphene will be on sustainability in everyday life, starting in May 2015.

      More about Moocs Moocs, an abbreviation of massive open online courses, are online courses aimed at unlimited participation and open access via the web. The term mooc was coined in 2008. As opposed to traditional distance learning, moocs do not have any prerequisites for admission. Exams are conducted by machine and there are platforms on which participants can get in contact with each other and discuss. The courses do not generate higher education credits, but the participants do receive a certificate for completing the course.

      Chalmers University of Technology conducts research and offers education in technology, science, shipping and architecture with a sustainable future as its global vision. Chalmers is well-known for providing an effective environment for innovation and has eight priority areas of international significance – Built Environment, Energy, Information and Communication Technology, Life Science, Materials Science, Nanoscience and Nanotechnology, Production, and Transportation.
      Graphene Flagship, an FET Flagship initiative by the European Commission, is coordinated by Chalmers. Situated in Gothenburg, Sweden, Chalmers has 11,000 full-time students and 3,000 employees.

      Two-dimensional materials –turning ideas into reality

      There has been much talk of the potential energy applications of graphene and related two-dimensional materials, and these applications are increasingly being realised in academic and industrial R&D laboratories the world over. Graphene manufacturers are coming up with new ways of producing the material in quantity, tailored for specific needs and contexts, and researchers are integrating graphene into novel devices and systems, continually assessing and refining their performance.


      Information exchange and the Graphene Flagship

      Taking stock of progress in energy applications for graphene and related materials, researchers and industrialists recently came together to listen, learn and exchange ideas. The Graphene Connect – Energy Applications workshop, which took place in Dresden from 20-21 October 2014, was organised by Europe’s Graphene Flagship, the world’s premier research and development initiative devoted to graphene and related two-dimensional nanomaterials.

      The Graphene Flagship is a science-driven, academic-industrial partnership which addresses grand scientific and technological challenges relating to graphene and related materials. Its vision is long term, bringing together scientists and engineers from across various countries and disciplines, all of whom share a unifying goal, and an ambitious plan on how to achieve it. The roadmap includes regular exchanges of ideas and information, and workshops such as Graphene Connect – Energy Applications are one of the primary means through which this dialogue takes place.


      Graphene in energy –an overview

      GC-Energy_350pxFollowing an introduction from Helena Theander, deputy leader of the Graphene Flagship’s innovation work package, the scene was set by Etienne Quesnel, a senior materials scientist at CEA in Grenoble, and leader of the flagship’s energy work package.

      In his keynote presentation, Dr Quesnel spoke of the key application areas for graphene in the energy sector. When it comes to energy generation, these include photovoltaic cells, thin film photovoltaics, dye-sensitised solar cells and quantum dot solar cells.




      Solar cells

      Dr Quesnel emphasised the potential of graphene in lowering device production costs, and as a replacement for indium tin oxide in photovoltaics. ITO is a brittle compound, which means that it cannot be used in flexible solar cells. Indium is also relatively scarce.

      Graphene is a promising material for solar cells, but it does not yet match the performance of ITO. Nevertheless, graphene can be functionalised and finely tuned for specific applications, and employed in combination with other materials. One may, for example, mix graphene nanoflakes from solution into the photo-anodes of solar cells, and process these electrodes at a temperature of less than 150 degrees, which is much lower than usual. Graphene also has the potential for replacing costly platinum in dye-sensitised solar cells.


      Batteries, supercapacitors and fuel cells

      Graphene as an additive in battery cathodes could lead to higher capacities, and the material improves electron migration during the charge-discharge process. Graphene anodes will give us higher specific capacities than with graphite, with a maximum measured value to date of 750 mAh per gramme, which is twice that of graphite anodes.

      Supercapacitors can also benefit from the use of graphene. High energy and power densities result from electrodes made of materials with high specific surface areas and conductivities, which makes graphene a most suitable material for this purpose. Other carbon nanomaterials such as nanotubes and fullerenes display similar properties, but one particularly interesting type of graphene comes in the form of petals grown perpendicularly to substrates over large surface areas. With graphene petals we can achieve specific capacitances in excess of 1,200 farads per gramme, and current densities of up to 100 amps per gramme.

      Cost is key when it comes to commercial exploitation of novel materials for energy storage, just as with other applications. Dr Quesnel outlined a low-cost process for producing graphene-based supercapacitors, which involves coating a DVD disc with a graphene-oxide layer supported on a flexible substrate, and chemically reducing this with the laser in a LightScribe drive. The laser-scribed graphene film is then peeled from the disc and transferred to the device substrate.

      Fuel cells can also benefit from graphene. The key here is in reducing if not removing the need for the precious metal platinum, used as a catalyst in the chemical reaction between hydrogen and oxygen which turns hydrogen fuel into electricity, leaving water as a byproduct. Dr Quesnel showed how graphene can be used to build a tuneable catalyst support which promotes better platinum adhesion and dispersion. Another strategy is to use an entirely metal-free cathode, with doped graphene as the catalyst. Doping polarises adjacent carbon atoms, and this facilitates catalytic activity.


      From proofs-of-concept to products

      In his summary, Dr Quesnel highlighted the collaboration between academic laboratories, applied research labs and materials producers in developing graphene-based proof-of-concept devices for energy applications. Converting these demonstrators into commercial products requires that researchers connect with other industrial players, and workshops such as Graphene Connect – Energy Applications provide the space for such collaborations.


      Overview to scientific detail

      Following Etienne Quesnel’s presentation, workshop participants heard from a number of other energy specialists from both academia and industry.

      Emmanuel Kymakis, an electrical engineer at the Technological Educational Institute of Crete, spoke of graphene-based organic solar cells, and the development of organic photovoltaics with improved efficiencies and lowered production costs. On the technical side, the exploitation of graphene in solar cells requires the tuning of material work function, for example with chlorine or nitrogen doping. In this way, graphene can lead to enhanced photo-generation and charge carrier transport. Dr Kymakis also discussed production processes, focusing on graphene ink printing and roll-to-roll manufacturing of photovoltaic films.

      Chemist Alkan Gürsel of Sabanci University in Turkey focused on the potential of graphene in fuel cells with a low platinum content. Graphene – in particular as chemically reduced graphene oxide – would provide catalyst support in such devices.

      Following Dr Gürsel came Toby Meyer, co-founder of Swiss solar cell manufacturer Solaronix. Dr Meyer spoke passionately about photovoltaic technology, with an emphasis on dye-sensitised and Perovskite solar cells. Solaronix specialises in dye-sensitised cells based on titanium dioxide and platinum, and in his plenary talk and subsequent discussions, Dr Meyer asked a number of pertinent questions concerning the feasibility of replacing platinum with graphene.

      Renault Mosdale of Grenoble-based Paxitech was another invited speaker from industry. Paxitech, founded in 2003 as a spin-off from the French government-funded research lab CEA, develops fuel cells and related systems and technologies. Fuel cell technology is a challenge to work with, noted Dr Mosdale, but it is developing apace, and Paxitech provides fuel cell manufacturers with components such as membranes and electrodes, with a particular focus on air-breathing fuel cell modules of up to 100 watts capacity for system integrators. Paxitech also produces complete fuel cell systems from five to a few hundred watts.

      Dr Mosdale told his audience in Dresden that he was initially sceptical about graphene, but has since been won over by the science and engineering arguments. He now appreciates the scope of graphene R&D, and its potential. Dr Mosdale is now talking detail, and asking about timescales for the exploitation of graphene in the fuel cell sector. On a technical level, he is looking to increase carbon support stability, and reduce voltage drops arising from the electrical resistance of cell components and interconnections.


      Group discussions

      GC-Energy_350_250pxFollowing the plenary presentations on the first day, the workshop broke up into smaller groups for networking and detailed discussions. Three groups met concurrently, with each focusing on a specific area such as energy conversion, technology beyond photovoltaics and fuel cells, and solar cells. Similarly, on the second day, workshop participants met to discuss energy distribution, batteries and supercapacitors, and hydrogen storage.

      In all of the group discussions there was enthusiastic and constructive dialogue between researchers and industrialists. Some questions were answered, others raised, and proposals for project collaborations put forward. Participants described the business networking opportunities afforded by the workshop as invaluable.




      Industrial perspectives

      The first day of the workshop ended with the participants continuing informally with discussions inspired by plenary presentations and group discussions earlier in the day. The second day of the workshop began with further presentations from invited speakers, this time with an emphasis on industry.

      Di Wei from Nokia Research in Cambridge looked at printed batteries incorporating graphene oxide. This production method is relatively cheap and scalable, but the graphene used has a higher resistivity than that intrinsic to high-quality graphene produced through chemical vapour deposition.

      Paolo Bondavalli from Thales, a French multinational which among other things provides R&D services to the aerospace, defence, transport and security sectors, discussed supercapacitors based on a combination of carbon nanomaterials. Thales works closely with academic researchers in France, and its researchers are building capacitors formed from graphene layers interspersed with carbon nanotube spacers. This arrangement leads to increased power as a result of greater ion penetration, and it also impedes the disintegration and delamination of device components.

      Further industrial perspectives were provided by Alberto Blázquez of CIDETEC, a firm which specialises in research and knowledge transfer in the areas of materials, surfaces and energy, and Amaia Zurutuza of Graphenea, a graphene-producing SME also based in the Basque Country of Spain.

      Dr Blazquez spoke about battery production, and Dr Zurutuza on the bulk production of graphene. Micromechanical exfoliation of graphene flakes produces high quality material, but it is a low yield process, and non-scalable. Liquid-phase exfoliation is higher yield, and is particularly suitable for ink production. Silicon sublimation of graphene is very expensive, and graphene produced by chemical vapour deposition can be difficult to transfer to different substrates. Dr Zurutuza noted that in 2013 the graphene production market was valued at €10m. This will rise in time, with the market responding to demand.


      A successful workshop

      Reflecting on the Graphene Connect – Energy Applications, workshop host Etienne Quesnel notes…

      “Feedback from participants was entirely positive. Surprising to me was the realisation that, despite intense media coverage of graphene these past few years, the industrial players present at the workshop were far from realising the full potential of graphene for energy applications. For example, substituting platinum with doped graphene into dye-sensitised solar cells or fuel cells is now more than a simple working assumption.

      “In this regard, the Graphene Connect event fully reached its target, disseminating the knowledge required to drive new industrial developments.”

      Upcoming Graphene Connect events include a workshop devoted to photonics and electronics, to be held in Barcelona from 3-4 February 2015, and one on materials and production, scheduled for 9 March 2015. Check out the Graphene Flagship website for further details.

      "VANCOUVER, BRITISH COLUMBIA and NEW YORK, NEW YORK--(Marketwired - Dec. 3, 2014) - Lomiko Metals Inc. ("Lomiko") (TSX VENTURE:LMR)(OTCQX:LMRMF)(FRANKFURT:DH8B) is very pleased to announce it has signed an agreement to invest in a new graphene-related venture, Graphene Energy Storage Devices (Graphene ESD Corp.), a U.S. Corporation. On December 4, 2013, Lomiko reported on a successful conclusion to Phase I of its Graphene Supercapacitor Project which involved Graphene Laboratories Inc. and Stony Brook University. Graphene ESD Corp. has been formed to commercialize the technology and bring the graphene-based energy storage devices to market.

      Supercapacitors bridge the gap between conventional capacitors and rechargeable batteries. They store the most energy per unit volume or mass (energy density) among capacitors. Supercapacitors power density is generally 10 to 100 times greater than normal capacitors or batteries. This results in much shorter charge/discharge cycles than batteries. Additionally, they will tolerate many more charge and discharge cycles than batteries. Incorporation of graphene material in supercapacitor electrodes may further improve energy and power density of the device. Graphene ESD Corp. will develop low-cost graphene-based supercapacitor devices that will be capable of even higher discharge currents. The development will focus on large-scale devices that are projected to have the lowest cost of power and stored energy in its class.

      "As reported December 4, 2013, the Phase I Graphene Supercapacitor project yielded encouraging results. Graphene ESD Corp. will build on the success of this project and will be developing a graphene-based supercapacitor. The device is designed as a versatile energy storage solution for electronics, electric vehicles and electric grid." stated A. Paul Gill, CEO of Lomiko Metals Inc. Graphene is finding new application in sensors, electronics, and advanced materials. Energy storage is a rapidly developing field which can benefit from the outstanding properties of graphene.

      Water Glides Freely Across “Nanodrapes” Made From the 'World’s Thinnest Material' - IT/RPI, RENSSELAER - Sep 25, 2013

      This innovation holds the potential to benefit lab-on-chip devices, high-throughput assays, self-cleaning surfaces, and many other applications requiring the motion of liquid drops on solid surfaces.


      Engineering researchers at Rensselaer Polytechnic Institute have developed a new drape made from graphene—the thinnest material known to science—which can enhance the water-resistant properties of materials with rough surfaces.

      These “nanodrapes” are less than a nanometer thick, chemically inert, and provide a layer of protection without changing the properties of the underlying material. The team of researchers, led by Rensselaer Professor Nikhil Koratkar, demonstrated how droplets of water encounter significantly less friction when moving across a surface covered with a nanodrape.

      This innovation holds the potential to benefit lab-on-chip devices, high-throughput assays, self-cleaning surfaces, and many other applications requiring the motion of liquid drops on solid surfaces.

      “Graphene nanodrapes are the thinnest, most sheer drapes we can imagine. Other than providing a barrier against water, these drapes are optically transparent and cause minimal changes to the topology of the underlying surface,” said Koratkar, the John A. Clark and Edward T. Crossan Professor of Engineering at Rensselaer. “We found this ultrasheer drape prevents the penetration of water into textured surfaces, which has interesting and potentially important technological implications for many applications in micro- and nanofluidics.”


      Drops of water can get easily stuck or “pinned” to a material with a nanotextured rough surface. When the droplet falls onto the material, the energy from the fall pushes out or displaces the tiny amounts of air trapped in the textured surface. Once in this pinned state, it is difficult to unpin the droplet and move it around the surface.

      Covering the surface with an impermeable graphene drape, however, prevents a droplet from getting pinned to the surface. The nanodrape creates a barrier that prevents the water drop from penetrating into and displacing the air from the textured surface. Instead, the droplet sits on top of the drape, with reduced friction between them, which in turn makes it easier to move the droplet around on the surface, Koratkar said. While helping to minimize this friction, the ultrasheer nanodrape causes minimal disruption to the underlying surface.

      The square nanodrapes measure several inches in length, and once applied to a surface are only detectable with a powerful microscope. Koratkar and the research team dropped small amounts of water on a surface of copper nanorods, and the same surface covered with a nanodrape. Water dropped on the bare surface spread out to form large flat drops indicative of a hydrophilic surface, while water dropped on nanodraped surfaces formed a much rounder or spherical drop indicative of a water-repellant or hydrophobic surface. The researchers also used high-speed cameras to observe and measure the shape of the drops as they impacted the surface, spread out, contracted, and finally settled. Once settled, the wettability of the surface was characterized by measuring the angle at which the liquid drop contacted the solid surface.

      Koratkar said the water-resistant properties are apparent after the application of a single nanodrape, but the properties are enhanced with the addition of a few additional layers. Nanometer-size cracks and wrinkles likely form in the first layer as it is applied and settles onto the surface. The second and subsequent layers likely suffer from fewer defects, and help to cover up defects on the first layer.

      Koratkar and his research team create the nanodrapes by growing graphene—a single layer of carbon atoms arranged like a nanoscale chicken-wire fence—on top of a copper substrate. They then coat the graphene with a polymer film, and use weak acids to remove or etch away the copper, which leaves the polymer layer with the graphene film underneath floating on the top of the liquid acids. The polymer layer with graphene sheet is then transferred to a surface, and the polymer layer is gently washed away using acetone. What remains is a single-carbon-atom thick, ultra-sheer, impermeable graphene drape.

      This study is the latest from Koratkar, whose research is positioned at the intersections of nanotechnology, energy, and sustainability. His work has focused on the synthesis, characterization, and application of nanoscale material systems, including graphene. His research group uses different techniques to investigate ways of incorporating these materials into various composites, coatings, and device applications. ..."

      Lithium-sulphur battery 'given graphene boost', Engineers have designed a cathode for lithium-sulphur batteries which features a thinly wrapped sheet of graphene, to boost performance - LT/UoC/TG/BIoT/LBL, CAMBRIDGE/BEIJING/BERKELEY/CALIFORNIA - Dec 16, 2014

      "


      Engineers have designed a cathode for lithium-sulphur batteries which features a thinly wrapped sheet of graphene to boost performance.

      The UK-China team consisting of researchers from the University of Cambridge and the Beijing Institute of Technology employed metal organic frameworks (MOFs) as a means of producing a conductive porous carbon cage in which sulphur is designed to act as the host and each sulphur-carbon nanoparticle is designed to act as energy storage units where electrochemical reactions occur.

      According to the researchers, MOFs are highly-prized thanks to their wide-ranging applications in hydrogen storage, carbon dioxide sequestration, catalysis and membranes - all of which could result in the commercialisation of performance-enhanced lithium-sulphur batteries.

      Lithium-sulphur batteries are said to boast theoretical specific energy densities considerably greater than those of their cousin, lithium-ion batteries.

      The UK-China team’s carbon scaffold design is engineered to act as a physical barrier to confine the active materials within its porous structure, the researchers said.

      “This leads to improved cycling stability and high efficiency,” said University of Cambridge research scientist Kai Xi.

      Xi and his research partners also found that by wrapping the sulphur-carbon energy storage unit within a thin sheet of flexible graphene, the speed at which electrons and ions could be transported was increased.

      “This work provides a basic, but flexible, approach to both enhance the use of sulphur and improve the cycle stability of batteries,” Xi said.

      “Modification of the unit or its framework by doping or polymer coating could take the performance to a whole new level.”

      According to Xi, the research team will now focus on fabricating hybrid free-standing sulphur cathode systems to achieve high-energy density batteries.

      “[That] will involve tailoring novel electrolyte components and building lithium ’protection layers’ to enhance the electrochemical performance of batteries,” he said.

      However, using graphene to enhance the energy storage capabilities of lithium-sulphur batteries is by no means a new concept.

      Researchers at Lawrence Berkeley Laboratories in California, for example, published a study earlier this year in which lithium-sulphur batteries were modified using graphene oxide.

      In that instance, the lithium-sulphur batteries were reported to have the ability to store more than twice the watt-hour per kilogram that their lithium-ion counterparts.

      An account of that research was covered in The Guardian newspaper in April. "

      Graphene brings quantum effects to electronic circuits, Research by scientists attached to the EC's Graphene Flagship has revealed a superfluid phase in ultra-low temperature 2D materials, creating the potential for electronic devices which dissipate very little energy - NW/EC, GF - Jan 21, 2015

      "Research by scientists attached to the EC's Graphene Flagship has revealed a superfluid phase in ultra-low temperature 2D materials, creating the potential for electronic devices which dissipate very little energy.

      At the atomic and molecular scales, the world can be a very strange place, with everyday notions of temperature, energy and physical coherence thrown into disarray. With reality at the quantum level we must talk of statistical likelihood and probability rather than simple billiard ball cause and effect.

      Take the concept of superfluidity, an ultra-cold state in which matter acts as a fluid with zero viscosity. You can think of superfluidity as a generalised thermodynamic analogue of the more commonly understood electrical superconductivity, whereby electrons move through materials without resistance and energy loss.



      Bose-Einstein condensation in graphene

      Superfluidity was first discovered in liquid helium, at temperatures of just a few degrees above absolute zero, but the phenomenon is evident at scales ranging from the atomic to the cosmic. It is related to the state of matter known as a Bose-Einstein condensate, in which a large fraction of the particles in bulk matter occupy the lowest quantum energy state. The particles, which at higher temperatures move around in a random, haphazard fashion, can in this way behave as a coherent or at least quasi-coherent whole, thus bringing quantum-mechanical effects into macroscopic visibility.

      Fascinating if somewhat esoteric physics it may be, but there is a practical side to superfluidity and Bose-Einstein condensation. For one thing it has implications for the behaviour of electronic devices, albeit specialist ones operating at ultra-low temperatures. To this end a group of researchers associated with Europe's Graphene Flagship have investigated the properties of electrons moving in two-dimensional structures formed from graphene and gallium arsenide.

      Graphene and Coulomb drag

      Graphene is crystalline carbon arranged in transparent, single atom-thick layers, with the carbon atoms set in a honeycomb-like lattice. The best known of the hundreds of two-dimensional materials discovered to date, graphene has a number of unique electrical, mechanical and other properties that give it huge potential for applications ranging from electronics to super-strong structures.

      Focusing on measurements of Coulomb drag – the frictional coupling between electric currents in spatially separated conductors – researchers from the Graphene Flagship, led by Marco Polini of the Nanoscience Institute of the National Research Council and Scuola Normale Superiore in Pisa, Italy, Vittorio Pellegrini, at the Graphene Labs of the Italian Institute of Technology in Genova, and Andrea Ferrari of the Cambridge Graphene Centre, have found that the drag resistivity increases markedly at temperatures of less than around 5 Kelvin (-268.15 Celsius). This is an unexpected result, departing as it does from the usual temperature dependence displayed in weakly-correlated Fermi liquids: a theoretical model which describes the behaviour of most electrically conductive materials at ultra-low temperatures.


      Electron flow in compound 2D structures

      In a paper published recently in the journal Nature Communications ("Anomalous low-temperature Coulomb drag in graphene-GaAs heterostructures"), the first author of which is Andrea Gamucci, the researchers report on a new class of compound electronic structures in which single or bi-layer graphene is set in close proximity to a quantum well made from gallium arsenide.

      A quantum well, formed from a semiconductor with discrete energy values, confines charged particle motion to a two-dimensional plane. Combining graphene with a quantum well results in a heterostructure formed from two different two-dimensional materials, and such a compound assembly may be used to investigate the interaction of electrons and electron holes. A hole is formed when an electron is excited into a higher energy state, leaving in its wake a quasi-particle which behaves as if it were a ‘missing’ electron, or an electron with positive rather than negative charge. Note that electron holes are not the same thing as the physically real anti-particles known as positrons.


      Superfluidity in 2D heterostructures

      In the case of the graphene-GaAs heterostructures reported in the Nature Communications paper, the Coulomb drag measurements are consistent with strong interactions between the material layers, with the attractive electrostatic force between electrons and holes in solid-state devices predicted to result in superfluidity and Bose-Einstein condensation. In other words, the strong interaction between material layers leads to quantum effects manifest in large ensembles of electrons and holes confined within micrometre-sized devices.

      "We show that such effects may happen when electrons are confined in a thin well made of gallium arsenide, with holes confined in monolayer or bilayer graphene," says Polini. "Electrons and holes separated by a few tens of nanometres attract each other through one of the strongest forces exhibited in nature – the electrical force. At sufficiently low temperatures, our experiments reveal the possible emergence of a superfluid phase, in which opposite currents flow in the two separate two-dimensional systems." Pellegrini continues: "Such currents flow with minimal dissipation, and may make possible a number of coherent electronic devices which dissipate little energy." Ferrari adds: "This is an another example of cutting edge results enabled by the deterministic assembly of graphene and other two-dimensional structures, which is precisely the overall target of the Graphene Flagship."


      Graphene in ultra-low temperature electronics

      Superfluidity and Bose-Einstein condensation are ultra-low temperature phenomena, so the effects described here in graphene-gallium arsenide heterostructures will not apply to everyday electronic devices. Still, there are many applications which require the use of cryogenically-cooled electronics, and these could exploit anomalous low-temperature Coulomb drag in bulk two-dimensional materials.
      Examples of such applications include high-performance and quantum computing, spectroscopy, magnetic and infrared sensing, and analogue-to-digital conversion. The discovery of the Graphene Flagship researchers outlined here could benefit these technology areas and more.

      "Transparent conductive coatings pervade modern technology. They are a critical component of optoelectronic devices such as smartphone and tablet displays as well as solar cells. The most widely used standard coating is indium tin oxide (ITO), although the use of carbon nanomaterials – carbon nanotubes and graphene – is on the rise.

      The search for novel transparent electrode materials with good stability, high transparency and excellent conductivity is driven by the required trade-off between transparency and conductivity: Metals are very conductive but not transparent; plastics are quite transparent but not conductive. However, many optoelectronic applications ideally require electrodes with both, high transparency and high conductivity.


      In new work, researchers nooooow have simultaneously increased the conductivity and transparency of ultra thin graphite – ranging from 3-60 graphene layers in thickness – by lithium intercalation, and have achieved the highest combined performance of sheet resistance and transmittance so far reported among all continuous thin-films.

      The researchers designed a methodology via a planar nanobattery that allowed them to conduct in situ studies of the electrical and optical properties of few-layer graphene sheets during electrochemical intercalation and deintercalation of lithium.

      "We doped few-layer graphene by inserting lithium in between the graphene layers," Jiayu Wan, a PhD student in Liangbing Hu's research group at the University of Maryland, tells Nanowerk. "As a result of this electrochemical intercalation, the Fermi level is upshifted by the doping effect, resulting in a more transparent and conductive material."


      Wan, together with Wenzhong Bao, is first author of a paper published in the July 1, 2014 online edition of Nature Communications ("Approaching the limits of transparency and conductivity in graphitic materials through lithium intercalation"). Hu's team collaborated with the research group of Michael Fuhrer at Monash University.

      In previous studies, researchers already tried to achieve a combined increase of both transmittance and conductivity. Some of the best results have been achieved by acid doping and FeCl3 intercalation (see for instance: "Novel Highly Conductive and Transparent Graphene-Based Conductors").

      "However, these previous doping/intercalation efforts just increased the conductivity compared to pristine few-layer graphene; the transmittance in the visible range at best stayed unchanged or even decreased," notes Wan.

      Hu points out that, due to the unusual band structure of graphene, lithium intercalation can simultaneously increase the DC electrical conductivity and increase optical transmission in the visible, allowing Li-intercalated few-layer graphene to achieve an unprecedented Figure of Merit σdc/σopt = 920, significantly higher than any other material and approaching the ultimate limit expected for doped graphene systems.

      As the lithium intercalated graphene material is not very stable in air, the team improved the stability of the intercalation compound with an air-tight sealing.

      "In addition to elucidating the limits of conductivity and transparency in ultrathin graphite, we expect that the experimental techniques developed here will be broadly useful for studying the intercalation dynamics and correlated optoelectronic properties of other 2D nanomaterials that can be intercalated electrochemically," concludes Hu.

      www.laboratorytalk.com/407371.article?slref=455879/158100/25

      "


      Scientists at Northwestern University, US have discovered that imperfect graphene creates a proton-selective membrane that could lead to improved fuel cells.

      Such improved fuel cells could be achieved because the speed at which imperfect graphene helps shuttle protons, and only protons, from one side of a graphene membrane to the other offers engineers a new and simpler mechanism for fuel cell design, the Northwestern researchers said.


      “Imagine an electric car that charges in the same time it takes to fill a car with gas,” said chemist Franz M. Geiger, who led the research.

      “And better yet, imagine an electric car that uses hydrogen as fuel, not fossil fuels or ethanol, and not electricity from the power grid, to charge a battery,” Geiger said.

      “Our surprising discovery provides an electrochemical mechanism that could make these things possible one day.”

      Geiger said that the trick :eek: to developing a proton-selective membrane is to purposely create imperfect graphene.


      “Everyone always strives to make really pristine graphene, but our data show if you want to get protons through, you need less :eek: :eek: perfect graphene,” Geiger said.

      By removing a few carbon atoms, the remaining atoms become highly reactive, which starts the proton shuttling process, Geiger said.

      “Our results will not make a fuel cell tomorrow, but it provides a mechanism for engineers to design a proton separation membrane that is far less complicated than what people had thought before,” Geiger said.

      “All you need is slightly imperfect single-layer graphene :eek: .” "

      The European nanotechnology roadmap, for graphene - NW/RSoC, NS/UoC, CAMBRIDGE - Feb 24, 2015
      www.nanowerk.com/nanotechnology-news/newsid=39155.php#at_pco…

      "In October 2013, academia and industry came together to form the Graphene Flagship. Now with 142 partners in 23 countries, and a growing number of associate members, the Graphene Flagship was established following a call from the European Commission to address big science and technology challenges of the day through long-term, multidisciplinary R&D efforts.


      In a 200-page open-access paper published in the Royal Society of Chemistry journal Nanoscale ("Science and technology roadmap for graphene, related two-dimensional crystals, and hybrid systems"), more than 60 academics and industrialists lay out a science and technology roadmap for graphene, related two-dimensional crystals, other 2D materials, and hybrid systems based on a combination of different 2D crystals and other nanomaterials. The roadmap covers the next ten years and beyond, and its objective is to guide the research community and industry toward the development of products based on graphene and related materials.




      - The science and technology roadmaps follow a hierarchical structure where the strategic level in a) is connected to the more detailed roadmap shown in b). These general roadmaps are the condensed form of the topical roadmaps presented in the previous sections, and give technological targets for key applications to become commercially competitive and the forecasts for when the targets are predicted to be met. (click on image to enlarge) -


      Graphene - a two-dimensional material made up of sheets of carbon atoms - and related materials are expected to revolutionise the fields in which they are applied, and they have the potential to become the materials of the 21st century. They will supplement and at times replace existing substances in a range of applications. Two-dimensional materials shall in some cases be integrated into existing platforms in order to enhance them. For example, graphene could be integrated into silicon photonics, exploiting established technology for constructing integrated circuits.

      The roadmap highlights three broad areas of activity. The first task is to identify new layered materials, assess their potential, and develop reliable, reproducible and safe means of producing them on an industrial scale. Identification of new device concepts enabled by 2D materials is also called for, along with the development of component technologies. The ultimate goal is to integrate components and structures based on 2D materials into systems capable of providing new functionalities and application areas.

      Eleven science and technology themes are identified in the roadmap. These are: fundamental science, health and environment, production, electronic devices, spintronics, photonics and optoelectronics, sensors, flexible electronics, energy conversion and storage, composite materials, and biomedical devices. The roadmap addresses each of these areas in turn, with timelines.


      Research areas outlined in the roadmap correspond broadly with current flagship work packages, with the addition of a work package devoted to the growing area of biomedical applications, to be included in the next phase of the flagship. A recent independent assessment has confirmed that the Graphene Flagship is firmly on course, with hundreds of research papers, numerous patents and marketable products to its name.

      Roadmap timelines predict that, before the end of the ten-year period of the flagship, products will be close to market in the areas of flexible electronics, composites, and energy, as well as advanced prototypes of silicon-integrated photonic devices, sensors, high-speed electronics, and biomedical devices.

      "This publication concludes a four-year effort to collect and coordinate state-of-the-art science and technology of graphene and related materials," says Andrea Ferrari, director of the Cambridge Graphene Centre, and chairman of the Executive Board of the Graphene Flagship. "We hope that this open-access roadmap will serve as the starting point for academia and industry in their efforts to take layered materials and composites from laboratory to market." Ferrari led the roadmap effort with Italian Institute of Technology physicist Francesco Bonaccorso, who is a Royal Society Newton Fellow of the University of Cambridge, and a Fellow of Hughes Hall.

      "We are very proud of the joint effort of the many authors who have produced this roadmap," says Jari Kinaret, director of the Graphene Flagship. "The roadmap forms a solid foundation for the graphene community in Europe to plan its activities for the coming years. It is not a static document, but will evolve to reflect progress in the field, and new applications identified and pursued by industry."

      - 11 new industrial partners join the Graphene Flagship as a result of an open Expression of Interest to bring in complementary competences and capabilities in specific areas, such as aerostructures manufacturing, biosensors, and supercapacitors. -


      The Graphene Flagship’s overriding goal is to take graphene and related materials from a state of raw potential to a point where they can revolutionise multiple industries. This requires the focus of the Flagship to evolve over the years, placing more resources in areas where this transition is more likely.

      “These Expressions of Interest are yet another step in the process of moving graphene from academic laboratories to society. The incoming companies will work closely with existing academic and industrial partners to facilitate this transition and strengthen the utilisation dimension of the Flagship” says Jari Kinaret, director of the Graphene Flagship.

      The Expression of Interest is meant to align work already on-going with the overall aims of the Flagship, and to transfer specific know-how not available in the present consortium, while at the same time providing the new partners access to competencies already present in the Flagship. The new partners will be incorporated in the scientific and technological work packages of the core project under the planned Horizon 2020 phase (1 April 2016 – 31 March 2018).


      The new partners of the Graphene Flagship are:

      - ABB (Sweden) –Nanocomposites topic one
      - AERNNOVA (Spain) –Aerostructures Manufacturer
      - AIDO (Spain) –Nanocomposites topic three
      - Alcatel-Lucent Italia (Italy) –Optoelectronics
      - FIDAMC (Spain) –Nanocomposites topic two
      - FlexEnable (UK) –Flexible Logic
      - Infineon (Germany) –Electronic Devices
      - M-Solv (UK) –Energy Applications
      - NanOsc AB (Sweden) –Spintronics
      - Novalia (UK) –Printed Prototypes
      - Prognomics Ltd (UK) –Chemical Sensors


      The Expression of Interest was initially announced on 26 January 2015, with eight main topics open for submission.

      - Nanocomposites
      - Electronic Devices
      - Aerostructures Manufacturer
      - Energy Applications
      - Flexibel Logic
      - Printed Prototypes
      - Chemical Sensors
      - Graphene Spintronics


      A ninth topic on Biomedical Technologies, associated with a new work package of the Flagship, was announced later in February.

      Led by Melbourne’s Swinburne University of Technology and including Dr Qin Li, from the Queensland Micro- and Nanotechnology Centre within Griffith’s School of Engineering, scientists have capitalised on the exceptional properties of graphene and are confident of applications in fields such as optical data storage, information processing and imaging.

      “While there is still work to be done, the prospect is of 3D images seemingly leaping out of the screens, thus promising a total immersion of real and virtual worlds without the need for cumbersome accessories such as 3D glasses,” says Dr Li.



      First isolated in the laboratory about a decade ago, graphene is pure carbon and one of the thinnest, lightest and strongest materials known to humankind. A supreme conductor of electricity and heat, much has been written about its mechanical, electronic, thermal and optical properties.

      “Graphene offers unprecedented prospects for developing flat displaying systems based on the intensity imitation within screens,” says Dr Li, who conducted carbon structure analysis for the research.

      “Our consortium, which also includes China’s Beijing Institute of Technology and Tsinghua University, has shown that patterns of photo-reduced graphene oxide (rGO) that are directly written by laser beam can produce wide-angle and full-colour 3D images.

      “This was achieved through the discovery that a single femtosecond (fs) laser pulse can reduce graphene oxide to rGO with a sub-wavelength-scale feature size and significantly differed refractive index.

      “Furthermore, the spectrally flat optical index modulation in rGOs enables wavelength-multiplexed holograms for full colour images.”

      Researchers say the sub-wavelength feature is particularly important because it allows for static holographic 3D images with a wide viewing angle up to 52 degrees.

      Such laser-direct writing of sub-wavelength rGO featured in dots and lines could revolutionise capabilities across a range of optical and electronic devices, formats and industry sectors.

      Graphene Sector Review, The Investors’ Guide to Graphene, 'Disruptive Technology, that is Opening the Door to a 'New Age in Industry' ' - Far East Capital - Feb 15, 2015

      - Warwick Grigor -

      - Investment Perspective:

      Graphene has been talked about in glowing terms with scientists, 'suggesting confidently that it is the 'key to the future of almost all :eek: :eek: materials'. Sooo revolutionary are its qualities, that they eeeven talk of the “graphene age”. The mooost common reaction of investors is that it is “too good to be true”, buuuuut beware of cynicism that may blind you to the opportunities

      Its 'disruptive qualities are one consideration, but investors want to knooow :eek: whaaaaat the path to commercialisation looks like, +how they are going to make money out of this new material'. There is nooo road map, but some parallels can be drawn with the path taken by the internet with graphene being to materials what the internet has been to communications.

      To start with the internet was about emails. A 'major breakthrough' occurred with the release of the 1st web browser, in '94, which turned the web into a user friendly graphical interface communications environment. As computing power increased +technology convergence accelerated, we have experienced the development of smart phones +wireless-based applications, offeringing flexibility +commercial opportunity, +'massive productivity gains', weeell beyond what was 1st contemplated.

      Commercialisation of graphene 'is poised to follow a similar trajectory'. Initially it is all about strength +flexibility, +enhancing the materials, to which it is added. Improved performance will lead to 'generational changes, +new opportunities', as industry starts to appreciate what is possible, +consumers demand their insatiable expectations for more, better, faster ...to be met.

      On a higher level, the order of magnitude increase in conductivity that graphene promises will lead to continual advancements, that will impact information transportation +communications, power storage, solar energy capture +'many other applications' that will be developed.

      The graphene technologies are only just starting to leave the laboratory. Supply has been the constraining factor, but not the cost. While it is expensive, a tiny amount goes a long way, so that the benefits already outweigh the cost factor.

      To date all the graphene in use is “made” via expensive laboratory processes. There is ooooone exception though. Talga Resources has a very high-grade graphite orebody, that enables direct production of graphene in a simple one step process, @nominal cost. This company could hold the key, to rapid development of more graphene applications, by solving the supply issue. Confirmation of this will depend upon pilot study results, planned for '15.

      There are very few vehicles by which investors can participate in this new industry. It is tooo early to be dogmatic, about which will be most successful, buuut it is nooooot too early to be dipping your toe in the
      water. The advantages will lie with those who grow with the sector.

      Wearing Graphene, Graphene has outstanding properties. Industry +researchers join forces to develop solutions for the use in textiles - MV - Apr 30, 2015

      - Martin Grolms -
      www.materialsviews.com/wearing-graphene/?utm_source=Material…

      "Graphene is ultra-thin and therefore transparent, an extremely efficient conductor of electricity and heat, with higher tensile strength than steel, yet flexible and abrasion-resistant and impermeable to gases. These outstanding properties of graphene mean that it has many potential uses in industry.

      While research is making rapid progress especially in the field of conductivity, the use of graphene in the textile sector has so far been somewhat overlooked. This is where a research project run by scientists at the Hohenstein Institut für Textilinnovation together with with the companies IoLiTec and Fuchshuber Techno-Tex, and Belgian project partners Centexbel and Soieries Elite. The team led by Roshan Paul is working within the EU research funding programme “M-era.Net”.


      “Over the next three years, the consortium will be investigating to what extent the surface of textiles can be changed using graphene modifications, in particular with a view to later applying the process to heat protective clothing. Graphene has all kinds of positive properties which would revolutionise this sector. This research makes us world leaders in using graphene modification on textile surfaces,” says Roshan Paul. The transformation of the various graphene modifications into stable aqueous dispersions is being carried out by Iolitec.

      The aim of the Hohenstein research team is to develop stable techniques for applying aqueous graphene dispersions, so that they can be used as a permanent coating on different textile surfaces. A range of different graphene modifications are being considered, since they have different properties.



      - Graphene has outstanding properties as a fire-resistant material. © Hohenstein Institute -


      The newly developed surface modifications for the various textiles will then be analyzed for their suitability for heat protective equipment. In the research work, Fuchshuber has the task of converting the application formula that has been developed to an industrial scale and ensuring that the treated textiles can be cleaned and processed. The aim is to produce a demonstrator model.

      Using graphene to modify the surface can significantly improve the flame-retardant properties of a textile. Graphene can act as a physical barrier, effectively preventing the penetration of heat and gases. At the same time, graphene also has the potential to prevent the thermal decomposition of the textile. Another benefit of graphene is its resistance to abrasion and rupture, about 200 times higher than that of steel. These qualities also make graphene extremely interesting for applications in the field of personal protective equipment (PPE).

      Normally, the functionalisation of textiles for PPE requires a multi-stage process. This may no longer be necessary if graphene can be applied in a single-stage process. The material used for PPE could then be thinner and therefore lighter. This in turn increases the wearer’s mobility.

      “If their functionality can be successfully proven, textiles with graphene-modified surfaces could find many uses in the PPE sector, especially in heat protective clothing,” says the project manager. This would open up a new market segment for the use of graphene. "

      Carbon Sciences - Announces Successful Production of High Quality Graphene, Using a 'Novel Low Cost CVD Process', Company Funded Research Project @UCSB Completes Initial Development, of a Graphene Fabrication Process +System - May 11, 2015
      www.carbonsciences.com/view_news.php?id=141

      "SANTA BARBARA, CA--(Marketwired - May 11, 2015) - Carbon Sciences Inc. (OTCBB: CABN), focused on the development of a breakthrough technology to mass-produce graphene, today announced that the research project funded by the company at the University of California, Santa Barbara ("UCSB"), has successfully demonstrated the production of high quality graphene using a low cost chemical vapor deposition ("CVD") process.


      Due to its breakthrough natural properties, many experts believe that graphene is the miracle material that will power the next generation of electronics, communication and composites. However, the key obstacle to the widespread use of graphene today is the high manufacturing cost of high quality graphene. The least expensive method, CVD, currently used in the electronics industry is still too expensive for enabling mass-market graphene applications such as flexible electronics, unbreakable touchscreens, sensors, and energy.

      The UCSB research team led by, Dr. Kaustav Banerjee, has successfully engineered a low cost CVD system that is optimized for graphene production using proprietary processes, catalysts and techniques. By fully optimizing and innovating various steps in the process the team has produced very high quality graphene. The system can also be used to customize doping to create application specific graphene.

      Bill Beifuss, CEO of Carbon Sciences, commented, "After a very intense and highly focused development effort by Dr. Banerjee's team, we are finally seeing very promising results. Now that the team has demonstrated a low cost laboratory method with proprietary processes, we can begin to look at transforming that into a viable commercial technology. Some of the steps in the process are truly innovative and are very likely to dramatically reduce the cost of making large quantities of graphene."

      Carbon Sciences is currently funding a year long sponsored research program at UCSB for the development of a low cost graphene manufacturing process.


      About Carbon Sciences, Inc.

      Carbon Sciences is focused on the development of a breakthrough technology to mass-produce graphene, the new miracle material. Graphene, a sheet of pure carbon that is only one atom thick, is flexible, transparent, impermeable to moisture, stronger than diamonds and more conductive than gold. Ever since the Nobel Prize was awarded for its discovery, experts believe graphene to be the miracle material that will enable revolutionary applications such as bendable touchscreen displays, rapid charge batteries, super-capacitors, low cost solar cells, extreme high-speed semiconductors, biosensors, as well as water purification. While the raw materials to make graphene are readily available, the lack of an industrial scale manufacturing process has hindered its commercial use. Carbon Sciences is supporting the development of a breakthrough process that will transform natural gas into commercial size sheets of graphene that can be fine-tuned with application-specific electrical and materials properties.

      Graphene 'to disrupt commodity demand', With miners looking for a turn in the market cycle, talk @the Sydney Resources Round-up looked further ahead, to new technologies - MA - May 13, 2015

      - Ben Hagemann -
      www.miningaustralia.com.au/news/graphene-to-disrupt-commodit…

      "The opening address of the Sydney Resources Round-up set a tone of optimism for Australian miners and investors, looking towards the next upswing in the market cycle, and the next investment opportunity.

      In his opening address, event organiser Stewart McDonald said he hoped for a quick return of the boom cycle, "especially for the older players" he quipped.

      Far East Capital executive chairman Warick Grigor followed the theme, beginning the first presentation of the day with a focus on seeking value in the lead up to the inevitable market upswing, despite it's unpredictable time-frame.




      "To kickstart the next cycle, we need optimists who can see opportunity," he said.

      Grigor was critical of investors he said had confused the concept of relative value of companies in the mining sector, saying there were too many who had failed to take into account the bigger picture of the market.

      "We're at the same place we've been many times before: we're at the bottom of the cycle, and the turning point is somewhat elongated as we seek to flush out the excesses of the previous bull market," he said.

      "There are too many junior companies that serve no purpose, and need to fail, because they're distracting us from those that have a future."

      Grigor said the current market climate was similar to that of the Dot.com boom of the early 'Noughties', and that today the best way for miners to enhance their stock value was to announce a technology deal.

      The long term future of the market would lie with the disruptive potential of nanotechnology, particularly in the case of the nanomaterial graphene, he said.

      "Graphene presents us with a generational change in techology, taking the field of nanoscience one step further.

      "Nanoscience has given us the ability to identify and seperate the materials which can be combined with other materials for performance levels not otherwise thought possible."

      With a barrage of examples of the uses and patented inventions made possible by graphene, Grigor explained that the supermaterial had the distruptive potential to affect demand for other mined commodities.

      Graphene can be added to exisiting materials and products to enhance their function and performance, and reduce the quantites required in production; such as when graphene is added to copper it can increase conductivity and reduce the material need for the tradtional commodity by up to 80 per cent.

      It can also be used in the manufacture of concrete, increasing it's strength and precluding the need for steel reinforcing altogether.

      Grigor also explained that the material strength of graphene, 200 times that of steel by weight, meant it could be used to create vastly stronger steel which would reduce the amount of iron ore required, and also reduce transport costs on the final product.

      "There has been an explosion in the number of patents being taken out, as industry has been preparing to take advantage of a new and deeply disruptive graphene age."

      The ability for miners to take advantage of this new market was limited to contributing graphite to the front end of the supply chain, sending it to specialist producers for manufacturing into usable graphene, Grigor said.

      However, he noted two exceptions to this problem, flagging Talga Resources as a potential leader in global graphene supply thanks to an "unusually high grade deposit of graphite in Sweden" and plans for a graphene production plant in Germany, as well as MRL Corporation in light of recent test work on their ultra-high grade deposit in Sri Lanka, and their potential for low-cost production of graphene.

      "Both of these companies could bring product to the market and massively undercut the price of graphene; in doing so they will be important facilitators to the large-scale commercialisation of graphene," he said.

      "Whether these companies become vertically integrated to benefit from multiple points in the value chain will depend on management and corporate objectives."

      World’s ‘Thinnest’ Light Bulb, Made From Graphene, Debuts - NG/UoC, SoE&AS/NN/UoI, NEW YORK/URBANA-CHAMPAIGN - Jun 15, 2015

      "

      - Light glows from a stretch of suspended graphene in this illustration of the discovery from a team of researchers in the U.S. and South Korea. -


      The quest for the better light bulb has taken yet another leap. This time, nanotechnology derives light from atom-thin strips of one of the world’s strongest materials: graphene.

      For the first time, scientists say they’ve created a flexible and transparent light source with carbon in its purest form. The
      y say their discovery could also eventually transform computers by using light rather than electronic circuits in semiconductor chips.



      “We’ve created what is essentially the world’s thinnest light bulb,” says Columbia University engineering professor James Hone in announcing the findings. He co-authored a study, published Monday on Nature Nanotechnology's website, by a team of researchers from South Korea, Columbia's Fu Foundation School of Engineering and Applied Science, Stanford University and University of Illinois at Urbana-Champaign.

      Their approach is notable even in the rapidly changing world of light bulbs. In recent years, as the United States and other countries have moved to phase out Thomas Edison’s century-old incandescent, the market has moved toward much more energy-efficient compact fluorescent lamps (CFLs) and light-emitting diodes (LEDs)—and beyond.

      Companies are offering new products. The Finally Light Bulb Company uses induction technology for its warm-glowing super-efficient Acandescent alternative, and Alkilu has portable OLED (organic LEDs) lamps that, unlike other bulbs, don’t have a backlight.

      Also, later this year, a graphene-coated LED that lasts longer and uses less energy than a typical LED is expected to enter the marketplace—the result of research at Britain’s University of Manchester. It’s not, though, a pure graphene light bulb. (Get the myths versus the facts on CFL and LED light bulbs.)

      “They’re using :eek: :eek: the graphene to increase the heat dissipation. Our study shows light emission from the graphene itself,” says Young Duck Kim, a postdoctoral research scientist at Columbia who led the latest work.

      Four years ago, he began observing light emissions from graphene, a newly discovered material that’s ultra lightweight but stronger than steel. He just didn’t know why it was happening.

      His team found that passing a current through a filament containing small strips of graphene could reach temperatures of more than 2500°C (4532°F), which is high enough to produce visible light. It did so without melting the metal electrodes to which they were attached. The reason? As graphene heats up, it becomes a poor conductor of heat, so the high temperature stays confined to a small spot in the center. In contrast, micro-scale metal wires cannot withstand such extreme heat. (Take the quiz: What You Don't Know About Energy-Efficient Lighting.)

      Their work takes a page from Edison’s playbook. “Edison originally used carbon as a filament for his light bulb, and here we are going back to the same element, but using it in its pure form—graphene—and at its ultimate size limit—one atom thick,” says study co-lead author Yun Daniel Park, professor of physics and astronomy at Seoul National University, in a press release.

      Kim says the team is seeking to commercialize the technology. He expects that could happen within five years, allowing manufacturers to use graphene to create flexible and transparent light displays.

      He says Intel and IBM are tackling the difficult task of integrating light into their computer chips. He expects that within about 10 years, his team’s work with graphene could also help make this a commercial success.

      "The UK welcomed an influx of graphene experts last week as Manchester University’s 200+ researchers working in the field of 2D materials were joined by hundreds more for Graphene Week 2015. The event, now in its 10th year, has grown from a small European workshop into a five-day conference boasting over 600 attendees and pushing the University Place venue to capacity. The scope of the programme has expanded too; hexagonal boron nitride (hBN), molybdenum disulphide (MoS2) and other related 2D materials have joined graphene on the ‘menu’ of structures being explored by developers. Most recently, the conference has been co-ordinated by the Graphene Flagship – a European drive to capitalize on the many opportunities for 2D materials, which launched in October 2013 and has adopted Graphene Week as its annual conference.


      The European Commission (EC) has given graphene and related 2D materials research a huge boost through its Flagship initiative, but as Thomas Skordas, head of the EC’s FET Flagships Unit, reminded the audience during the conference opening – the funding is not a blank cheque for 10 years. The objective is to deliver economic benefits. So far, Graphene Flagship projects have generated 3x more publications compared with the Horizon 2020 average, but to achieve its long term goal the programme needs to capitalize on this research growth.



      - Plenary update: Nobel Prize winner Kostya Novoselov briefed the Graphene Week 2015 audience on major developments in the field of 2D materials. -


      Connecting with industry

      The challenge of taking graphene and related 2D materials from the lab to the market is a focus issue for TMR+ and its sister journal Translational Materials Research (TMR), and we were delighted to be invited to the Flagship’s latest Graphene Connect workshop, co-located with Graphene Week 2015, to join in the discussion.

      The Manchester session was focused on investment opportunities in graphene and related 2D materials, and put the spotlight on start-ups and early-stage companies. Fittingly, the workshop took place at the recently opened National Graphene Institute (NGI) – a facility where academia and industry are co-located to promote translation of 2D materials from the lab to the market.

      Presenters from the VC community included Achim Hoffman of IP Group. He picked up on the issue of media hype surrounding graphene, which has distorted expectations. One of the key messages from the session was the need to stay focused on the fundamentals such as the market, the technology and the infrastructure. “You’ve got to go back :eek: :eek: to basics,” summed up MTI’s Mark Rahn, who also spoke @the event.



      - New facility: the Graphene Connect networking event focusing on investment opportunities was held at the UK’s National Graphene Institute in Manchester. -


      Rahn presented a snapshot of companies operating in the graphene sector. Today, materials suppliers are putting resource into stepping up the value chain by offering functionalized products and formulations that are easier for customers to evaluate and integrate. “The real hard work is how you get from a good idea to a viable production process,” said Nigel Salter, Managing Director of 2DTech – a start-up supplying graphene nanoplatelets (GNPs).

      Other industrial players at the workshop included BGT Materials, a 2D materials venture with a base in the UK and a sister operation in Taiwan. According to its UK manager – Liam Britnell – BGT has developed an environmentally-friendly way to process graphene-oxide (GO). Applications include barrier films for food packaging, which exploits the material’s very low oxygen transmission characteristics.

      Whether it’s packaging or microelectronics, materials firms need to understand their potential markets and make sure that their products and processes are compatible with their target industries. To accelerate this process, Applied Nanolayers (ANL) – which grew out of Leiden University – decided to break the cord from academia early on and moved south to base itself in the heart of the Netherlands’ chip-making ecosystem. The company provides wafer-grown 2D material such as graphene or hBN for a range of device applications.

      Business briefing

      The final panel discussion of the day, which featured Graphenea, Haydale and Flexenable, highlighted the many different routes for growing and repositioning businesses in the advanced materials sector – topics that TMR will be exploring in more detail through its journal section ‘Policy, funding and business strategy’.

      - Graphenea began as a supplier of 2D materials for the research community, but the firm’s products also appeal to industry and in 2013 it won investment from Repsol – a multinational with activities upstream and downstream in the oil & gas sector. Most recently, Graphenea has been awarded Euro 2.5 million through the Horizon 2020 SME instrument – a phased programme of support to small-to-medium enterprises – which will allow the San Sebastian headquartered company to further scale-up its production capacity. The firm has a satellite office based in Boston, US, to strengthen its links with MIT and Harvard.

      - Haydale has raised capital by floating on the London Stock Exchange, and recently acquired EPL Composites, which gives the firm an immediate route into this applications area. Haydale has built a strong case for the benefits of graphene functionalization through independent testing of its materials by the UK’s national measurement institute – NPL.

      - FlexEnable was spun out of Plastic Logic to give the business more freedom to apply its expertise in printing transistors on plastic beyond the display sector. Its activities include consulting services to materials companies.


      Meanwhile, back @Graphene Week

      There was plenty of industry input at the main conference too with updates from Bosch, IBM and Alcatel Lucent, to name just a few of the big names eyeing up opportunities for 2D materials. TMR+ spoke with IBM’s Shu-Jen Han last year, and the message remains the same in 2015 – RF devices rather than digital logic are a stronger proposition for graphene. Telecomms could be a promising area for the material thanks to graphene’s consistent performance across a wide temperature range, and useful optical properties.

      Alcatel Lucent has been working with partner AMO Aachen to investigate the potential of 2D materials in enabling highly-integrated photonic subsystems. The team has come up with a photodetector featuring CVD-grown graphene on a Si waveguide, which operates in the c-band (wavelength = 1550 nm) to support data rates up to 50 GBit/s.

      The next Graphene Connect workshop is scheduled for early 2016 and will explore the topic of biosensors and implants. Graphene Week 2016 will take place in Poland next June.

      Samsung invents longer lasting battery, Samsung battery breakthrough to double battery life. The graphene layers anchored onto the silicon surface accommodate the volume expansion of silicon via a sliding process between adjacent graphene layers. When paired with a commercial lithium cobalt oxide - DT/S/TT/N - Jun 27, 2015

      - Larry Banks -
      http://tech.thaivisa.com/samsung-battery-breakthrough-to-dou…

      "


      The research team over at Samsung has found a way to almost double the capacity of lithium ion batteries, according to new reports this week. The research arm of the company has found a way to make a new type of silicon cathode material for coating the graphene of the silicon surface of batteries, which means it can support almost twice the energy level of current battery tech.


      Samsung invents longer lasting battery


      Some of the details of the discovery were revealed in Nature.com.


      The graphene layers anchored onto the silicon surface accommodate the volume expansion of silicon via a sliding process between adjacent graphene layers. When paired with a commercial lithium cobalt oxide cathode, the silicon carbide-free graphene coating allows the full cell to reach volumetric energy densities of 972 and 700 Wh l−1 at first and 200th cycle, respectively, 1.8 and 1.5 times higher than those of current commercial lithium-ion batteries.


      However, for most people, the improvements in the lithium ion battery density have typically meant that companies can create smaller batteries, rather than longer lasting ones. As our smartphones become ever more thin and sleek, with companies like Apple at the front of the race, the batteries also need to be smaller too, but also provide at least a full day’s usage. So even though we can expect slimmer devices and an improvement in battery life, in practice we probably can’t expect new phones with double the typical battery life anytime soon.

      Many people have been waiting for significant battery life improvements for many years, and of course lots would argue that thinness should not be at the expense of a decent battery life. Other components used in smartphones on the other hand have witnessed huge improvements over the last few years, such as improved cameras, higher resolution screens and better colour accuracy.

      But the time has come for a breakthrough in battery tech. Lithium ion has been in use now since the early 90s, after all… "

      British firm seeks to fund graphene strategy, via Oriana(V.OUP.H) RTO - SH - Jul 25, 2015

      - Peter Kennedy -
      www.stockhouse.com/news/newswire/2015/07/24/british-firm-see…

      "Graphene Lighting PLC., a British company that is aiming to capitalize on graphene technology developed in the United Kingdom, is moving to fund its strategy by gaining a stock exchange listing in Canada.

      The British firm has signed a letter of intent to engage in a reverse takeover with Canadian capital pool company Oriana Resources Corp. (TSX: V.OUP.H, Stock Forum).


      Graphene is a super conductor with many extraordinary properties. It is known to be ultra-light, incredibly flexible and yet is 200 times stronger than steel.

      The allotrope of carbon was originally isolated from graphite (an industrial mineral) in 2004 by two researchers who were working at the University of Manchester.

      Gaining a stock exchange listing in Canada is in line with Graphene Lighting’s bid to become a global leader and supplier of graphene-enabled light bulbs and lighting systems, utilizing graphene technology and knowledge developed by the two Manchester University researchers.

      Under the terms of the letter of intent that was announced on Friday, Oriana and Graphene Lighting will complete the reverse takeover by way of a share exchange arrangement that will make Graphene a wholly-owned subsidiary of Oriana.

      However, completion of the combination is subject to a number of conditions.

      They include the closing by Graphene Lighting of a $5 million brokered private placement of subscription receipts led by Industrial Alliance Securities Inc. and First Republic Capital Corp.

      Financing proceeds will be used execute Graphene Lighting’s product development, sales and marketing strategy.

      If the reverse takeover proceeds, six shares of Oriana will be exchanged for each common share of Graphene.

      The combined company would then hold all of Graphene Lighting’s assets, and conduct business under the Graphene Lighting Inc. banner.

      Under the transaction, six shares of Oriana will be exchanged for each one common share of Graphene Lighting, and one share of Graphene Lighting PLC will be exchanged for one common share of Graphene Lighting Inc.

      That would leave Graphene Lighting with 33.4 million shares outstanding.

      “We are delighted with the rapid progress we’ve made on all fronts as we look to commercialize our technology,’’ Professor Colin Bailey, who will serve as the company’s inaugural Chairman.

      He said the company’s new CEO will be Bill Neill, a former advertising rep, and ex-publisher of Canada’s Financial Post newspaper.

      “His expertise and management experience, particularly with public companies, are ideally suited for the company as we launch Graphene Lighting,’’ Bailey said. "

      $5,000,000 investment in Angstron Materials 'accelerates graphene commercialization' - TMR+ - Jul 31, 2015

      - James Tyrrell -
      http://tmrplus.iop.org/2015/07/31/5-million-investment-in-an…
      http://iopscience.iop.org/2053-1613/2/2/020301/article

      "Angstron Materials, a US supplier of single and few-layer graphene materials, announced this week that it has secured $5 million in capital to increase manufacturing capacity and bring key technologies such as its thermal management products to market. Heat spreaders developed by the firm can reduce hot-spots in mobile phones and other handheld devices, and the funding news follows reports earlier this year that Angstron’s graphene sheets have been qualified for use by a major mobile electronics company.



      Thermal interface material: Angstron Materials supplies graphene-based sheets in thicknesses ranging from 5 µm to 40 µm with thermal conductivity between 800 W/m.K and 1700 W/m.K for use in electronic products such as tablets, laptops and flat screen TVs. The foils can also be used for EMI shielding.


      Estimates by market analyst IDTechEx suggest that 55% of electronic failures are caused by over-heating, and enhanced thermal interface materials have a major role to play in helping devices to stay cool, perform better and last longer as developers boost their offerings by packing more processing power into increasingly compact form-factors.

      “We use the planar alignment of carbon atoms to make a lightweight, flexible thermal foil with up to 1700 W/m.K in-plane thermal conductivity – substantially higher thermal conductivity than copper and offering weight savings for thermal management,” Claire Rutiser, a member of Angstron’s executive team, told TMR+. “Also, we can load thermally conductive nano graphene platelets (NGP) into a matrix – which could be thermoset, thermoplastic or non-curing (for thermal paste).”

      Graphene isn’t the only option for device makers and competing thermal management materials include formulations based on silver flakes or silver nano-wires, but there are economic considerations that may favour the use of NGPs. “Silver is subject to significant price fluctuation and future price uncertainty,” Rutiser comments. “Angstron Materials has known input materials pricing and is able to enter into long term supply agreements with end users.”

      Graphene has been linked with various big names in portable electronics. In 2011, Apple noted that the use of graphene thermal dissipators goes beyond cooling. Related applications include transferring heat from onboard electronics to the battery to improve runtime, which can be compromised at low temperatures.


      Multiple markets

      Rutiser says that Angstron is ready with scalable production capacity and emphasised that the firm is targeting other sectors in addition to thermal management materials. She’s optimistic that over a 10 year period energy storage will grow to become one of the company’s biggest sources of revenue. Driving this are developments in graphene-wrapped silicon anodes by sister company Nanotek Instruments, which allow fabrication of Li-ion batteries with over 400 Wh/kg, and also materials for supercapacitors.

      “Affordable, high-capacity energy storage is critical for the transition to electric vehicles and for grid-stabilization as the percentage of energy derived from renewables increases in the coming decades,” Rutiser explained. “These products have comparatively long qualification times due to reliability testing and industry safety standards.”

      Currently, Angstron’s graphene-enhanced products and technologies are linked to five distinct portfolios – thermal management materials, energy storage systems, nanocomposites, transparent conductive films, paints and coatings. “Graphene platelets are inert to most chemical species and offer opportunities to improve barrier coatings against corrosion, chemical attack, or oxygen permeation, “ added Rutiser.

      Graphene given recycling boost, Engineers @the Graphene Flagship have demonstrated a recyclable technique that yields cost-effective, high-quality graphene - LT/GF, EU/SA/RWTHAU, IoP/FCJ, AACHEN/JÜLICH - Aug 10, 2015
      www.laboratorytalk.com/407563.article?slref=455879/184194/25
      http://advances.sciencemag.org/content/1/6/e1500222

      "


      Engineers at the Graphene Flagship have demonstrated a recyclable technique that yields cost-effective, high-quality graphene.

      The technique, which has been designed to enhance the traditional method of synthesising graphene via the chemical vapour deposition (CVD) of methane gas onto a copper substrate, permits researchers to peel graphene flakes from a CVD substrate with minimal chemical contamination.


      To avoid such chemical contamination, the research team - which comprised Flagship-affiliated physicists from RWTH Aachen University, Germany and German research centre, Forschungszentrum Jülich - incorporated strong van der Waals interactions between graphene and boron nitride into its method.

      The van der Waals interaction is the attractive sum of short-range electric dipole interactions between uncharged molecules - a force that ultimately allowed the Graphene Flagship research team to separate CVD graphene from the copper substrate and transfer it to an arbitrary substrate.

      According to the research team, the newly developed process also allows for the re-use of the catalyst copper foil in further growth cycles, and minimises contamination of the graphene due to processing.

      What’s more, no noticeable performance changes were detected between devices developed in the first and subsequent growth cycles - a breakthrough that confirms the copper as a recyclable resource in the graphene fabrication process, the researchers said.

      “Chemical vapour deposition is a highly scalable and cost-efficient technology,” said Christoph Stampfer, head of the 2nd Institute of Physics A at Aachen University.

      “Until now, graphene synthesised this way has been significantly lower in quality than that obtained with the ’scotch-tape’ method, especially when it comes to the material’s electronic properties. But no longer,” Stampfer said.

      Via the scotch-tape method, layers of sticky tape are used to peel graphene flakes from a piece of graphite, thereby obtaining micrometre graphene sheets - a process that is not considered industrially viable.

      However, Stampfer said his team’s process is, “in principle”, suitable for industrial-scale production, and narrows the gap between graphene research and its technological applications.

      A full account of the research has been published in the journal Sciences Advances. "

      Business school mines big data, for clues on graphene commercialization - TMR+/N - Aug 20, 2015

      "What can web scraping reveal about the commercialization of graphene? That’s the question Philip Shapira, Abdullah Gök and Fatemeh Salehi Yazdi have set out to answer using a mixture of computerized data mining and other analytical techniques.

      The team, based at Manchester Business School, has chosen graphene as a ‘demonstrator’ to road-test its approach, which identifies patterns from publicly available information hosted on enterprise websites. The hope is that these methods can assist in providing ‘real-time intelligence’ to map the development of rapidly emerging materials and technologies.

      In the pilot study, Shapira and his colleagues have focused on a set of 65 graphene-based small and medium-sized enterprises (SMEs) based in 16 different countries – 49.2% of the SMEs in the sample are located in North America, 15.4% in the UK, 18.5% in Western Europe and 16.9% in East Asia and emerging nations. The researchers acknowledge that they haven’t captured every graphene SME in every country, particularly in China, and note this under-representation should be kept in mind when comparing across the regions.


      Presenting their findings in a Nesta working paper, the authors draw attention to the following

      - Access to finance and the firms’ location are significant factors that are associated with graphene product introductions.
      - Patents and scientific publications are not statistically significant predictors of product development in their sample of graphene SMEs.
      - Graphene SMEs are focusing mainly on upstream and intermediate offerings in the value chain.


      Graphene advantage?

      According to the data, the mention of other 2D materials on a company website turned out to be a significantly negative predictor of introducing a product into the market. “In other words, focusing on graphene was more likely to be associated with a product introduction – perhaps because other 2D materials are as yet further away from being ready for the market or because focusing on multiple materials in a resource-constrained SME might diffuse or slow down commercialisation capabilities,” comment the authors in their work.

      Supporting movement, up the value chain

      As the researchers note, currently there is an emphasis in SMEs on producing advanced graphene materials, although many are signalling plans to develop more intermediate graphene products that should have higher value in the marketplace. Technology intermediary organisations are likely to be important in supporting these next stages of graphene development – examples include the UK National Graphene Institute, which opened in March this year, and its sister facility the Graphene Engineering Innovation Centre, which is planned for completion in 2017.

      Talga 'Triples Swedish Graphite Resource, to Global Scale' - MA - Aug 28, 2015

      www.miningaustralia.com.au/news/talga-triples-swedish-graphi…
      www.techmetalsresearch.com/metrics-indices/tmr-advanced-grap…

      "Perth-based graphite explorer Talga Resources has announced their maiden JORC mineral resource in Sweden has tripled their prospect .

      The Jalkunen graphite inferred resource of 31.5 million tonnes at 14.9 per cent has contained graphite of 4.63 million tonnes, bringing the Talga’s total graphite inventory in Sweden to 6.9 million tonnes.

      The new announcement is the latest in a series of positive moves in recent months, including the start of trial mining at the Vittangi project, where blocks of graphite are quarried from the ground using block-sawing techniques, similar to architectural stone quarrying.


      Talga has also recently sold options for three out of four of its Australian gold projects to Beatons Creek Gold (a subsidiary of Novo Gold Corporation), in order to on graphite and graphene opportunities in Europe.

      In July Talga began trucking graphite from Vittangi to their storage and processing facility in Rudolstadt, Germany, where phase 1 commissioning will begin.

      Phase 1 will see a world first in direct-from-ore exfoliation method for extracting kilogram quantities of graphene and nano-grade graphite.

      Managing director Mark Thompson said the new Jalkunen resource estimate was extremely encouraging on several fronts.

      “Not only does it elevate the project from target to resource status, it springboards into the top nine graphite deposits by size and is within top six for grade of worldwide graphite resources,” he said.

      “This is significant as this was the first drill test by Talga and required relatively few holes, so the deposit has a high potential for further growth if required.

      “Also, the Jalkunen resource sits close to the previously announced Jalkunen Exploration Target which provides encouragement regarding endowment of the remaining graphite Exploration Target portfolio.”

      At present Talga have a suite of five projects in Sweden comprising 30 separate deposits of high grade graphite

      Talga’s Vittangi project has been rated number one according to the Technology Metals Research Advanced Graphite Projects Index.

      Unprocessed raw graphite ore from Vittangi at 24.4 per cent total carbon has been shown to exhibit similar characteristics, including conductivity, to highly purified synthetic graphite, enabling simpler low-cost processing techniques. "

      - Schematic of the ionic polymer-graphene composite (IPGC) actuator or “motor”. When an electric field is applied, the redistribution of ions causes the structure to bend.
      Copyright : Korea Advanced Institute of Science and Technology -


      Researchers in South Korea have developed an electrode consisting of a single-atom-thick layer of carbon to help make more durable artificial muscles

      Ionic polymer metal composites (IPMCs), often referred to as artificial muscles, are electro-active polymer actuators that change in size or shape when stimulated by an electric field. IPMCs have been extensively investigated for their potential use in robotics inspired by nature, such as underwater vehicles propelled by fish-like fins, and in rehabilitation devices for people with disabilities.


      An IPMC “motor”, or actuator, is formed from a molecular membrane stretched between two metal electrodes. When an electric field is applied to the actuator, the resulting migration and redistribution of ions in the membrane causes the structure to bend. IPMC actuators are known for their low power consumption, as well as their ability to bend under low voltage and to mimic movements that occur naturally in the environment.

      They have a major disadvantage, however. Cracks can form on the metal electrodes after a period of exposure to air and electric currents. This can lead to the leakage of ions through the electrodes, resulting in reduced performance.

      Improving the durability of IPMC actuators is a major challenge in the field of artificial muscles. Researchers are investigating ways to develop a flexible, cost-effective, highly conductive and crack-free electrode that can be used to construct a durable polymer actuator.

      In a paper published in ACS Nano, researchers from the Korea Advanced Institute of Science and Technology report the development of a thin-film electrode based on a novel ionic polymer-graphene composite (IPGC). Graphene is a single-atom-thick layer of carbon with exceptional mechanical, electrical and thermal properties. The new electrodes have a smooth outer surface that repels water and doesn’t have apparent cracks, which makes them nearly impermeable to liquids. They also have a rough inner surface, which facilitates the migration of ions within the membrane to stimulate bending.

      The new IPGC actuator demonstrates exceptional durability without apparent degradation, even under very high input voltage. It shows promise for use in biomedical devices, “biomimetic” robots that mimic movements occurring in nature, and flexible soft electronics.

      The researchers acknowledge that there are still many challenges and more research is needed to realise the full potential of the graphene-based electrodes and their subsequent commercialisation. In 2015, they plan to further enhance the bending performance of the actuators, their ability to store energy and their power.

      They also plan to develop a biomimetic robot that can walk and jump on water like a water strider. ..."

      www.graphene-info.com/graphenano

      "According to a report from a Chinese website, The Spanish Graphenano, along with the University of Cordoba and Grabat Energy, developed a polymeric graphene battery, especially suited for electric cars, that will be cheaper and lighter than conventional batteries and will run 1000km on a 10 minute charge. Graphenano claims that this revolutionary battery will be put into production in 2015.

      Polymeric batteries can have a longer lifetime compared to conventional hybrid ones (up to four times!) and due to graphene's light weight, the battery itself will be light enough to improve the electric car's fuel efficiency.


      This battery is even supposed to be 77% cheaper than lithium batteries, and it is rumored that prototypes have already been sent to several German car manufacturers, which at this time remain undisclosed.


      Back in August 2014, Tesla's CEO said the company is developing a new battery technology that will almost double the capacity of its Li-Ion batteries. It was reported that Tesla is also looking into graphene technology for this project. "

      The ABC reports that the company, with has 100 per cent ownership of five graphite assets in Sweden, is working to produce new materials for longer-lasting, more efficient batteries.


      "Our rocks are so high grade and so pure that it actually conducts electricity all by itself," managing director Mark Thompson told the ABC.





      "For better batteries - ones that charge faster and last longer and are much cheaper to use in things like solar or green energy processing - you need a better performing battery, that is more conductive, lighter and cheaper, graphene achieves that."

      A pioneering new technique to produce high-quality, low cost graphene could pave the way for the development of the first truly flexible ‘electronic skin’, that could be used in robots.

      Researchers from the University of Exeter have discovered an innovative new method to produce the wonder material Graphene significantly cheaper, and easier, than previously possible.



      The research team, led by Professor Monica Craciun, have used this new technique to create the first transparent and flexible touch-sensor that could enable the development of artificial skin for use in robot manufacturing. Professor Craciun, from Exeter’s Engineering department, believes the new discovery could pave the way for “a graphene-driven industrial revolution” to take place.

      She said: “The vision for a ‘graphene-driven industrial revolution’ is motivating intensive research on the synthesis of high quality and low cost graphene. Currently, industrial graphene is produced using a technique called Chemical Vapour Deposition (CVD). Although there have been significant advances in recent years in this technique, it is still an expensive and time consuming process.”

      The Exeter researchers have now discovered a new technique, which grows graphene in an industrial cold wall CVD system, a state-of-the-art piece of equipment recently developed by UK graphene company Moorfield.

      This so-called nanoCVD system is based on a concept already used for other manufacturing purposes in the semiconductor industry. This shows to the semiconductor industry for the very first time a way to potentially mass produce graphene with present facilities rather than requiring them to build new manufacturing plants. This new technique grows graphene 100 times faster than conventional methods, reduces costs by 99 % and has enhanced electronic quality.

      These research findings are published in the leading scientific journal, Advanced Materials.

      Dr Jon Edgeworth, Technical Director at Moorfield said: “We are very excited about the potential of this breakthrough using Moorfield’s technology and look forward to seeing where it can take the graphene industry in the future.”

      Professor Seigo Tarucha from the University of Tokyo, coordinator of the Global Center of Excellence for Physics at Tokyo university and director of the Quantum Functional System Research Group at Riken Center for Emergent Matter Science said: “The ability to manufacture high quality, large area graphene (at a low cost) is essential for advancing this exciting material from pure science and proof-of-concept into the realm of conventional and quantum electronic applications. After starting the collaboration with Professor Craciun’s group, we are using Exeter CVD grown graphene instead of the exfoliated material in our graphene-based devices, whenever possible.”

      The research team used this new technique to create the first graphene-based transparent and flexible touch sensor. The team believes that the sensors can be used not just to create more flexible electronics, but also a truly-flexible electronic skin that could be used to revolutionise robots of the future. ..."

      1st superconducting graphene created, by UBC researchers, Graphene, the ultra-thin, ultra-strong material made from a single layer of carbon atoms, just got a little more extreme. University of British Columbia(UBC) physicists have been able to create the 1st ever superconducting graphene sample, by coating it with lithium atoms

      "Graphene, the ultra-thin, ultra-strong material made from a single layer of carbon atoms, just got a little more extreme. University of British Columbia (UBC) physicists have been able to create the first ever superconducting graphene sample by coating it with lithium atoms.

      Decorating monolayer graphene with a layer of lithium atoms enhances the graphene’s electron–phonon coupling to the point where superconductivity can be induced.

      Although superconductivity has already been observed in intercalated bulk graphite–three-dimensional crystals layered with alkali metal atoms, based on the graphite used in pencils–inducing superconductivity in single-layer graphene has until now eluded scientists.


      “This first experimental realization of superconductivity in graphene promises to usher us in a new era of graphene electronics and nanoscale quantum devices,” says Andrea Damascelli, director of UBC’s Quantum Matter Institute and lead scientist of the Proceedings of the National Academy of Sciences study outlining the discovery.


      Graphene, roughly 200 times stronger than steel by weight, is a single layer of carbon atoms arranged in a honeycomb pattern. Along with studying its extreme physical properties, scientists eventually hope to make very fast transistors, semiconductors, sensors and transparent electrodes using graphene.

      “This is an amazing material,'” says Bart Ludbrook, first author on the PNAS paper and a former PhD researcher in Damascelli’s group at UBC. “Decorating monolayer graphene with a layer of lithium atoms enhances the graphene’s electron-phonon coupling to the point where superconductivity can be stabilized.”

      Given the massive scientific and technological interest, the ability to induce superconductivity in single-layer graphene promises to have significant cross-disciplinary impacts. According to financial reports, the global market for graphene reached $9 million in 2014 with most sales in the semiconductor, electronics, battery, energy, and composites industries.

      The researchers, which include colleagues at the Max Planck Institute for Solid State Research through the joint Max-Planck-UBC Centre for Quantum Materials, prepared the Li-decorated graphene in ultra-high vacuum conditions and at ultra-low temperatures (5 K or -449 F or -267 C), to achieve this breakthrough. ..."

      Mit 'Graphen in den olympischen Sommer'

      www.wallstreet-online.de/nachricht/8095029-rohstoffe-graphen…

      "Graphen, der Stoff der Zukunft, wird seinen Siegeszug antreten, wenn er günstiger in der Herstellung wird.

      Großveranstaltungen sind ein gutes Schaufenster für Innovationen. Das sollte auch für die olympischen Spiele 2016 in Brasilien zutreffen. Einige Vorteile von Graphen könnten dann auch für die breite Öffentlichkeit sichtbar werden.

      „Sobald Graphen kosteneffizient massenhaft hergestellt werden kann, könnten die Auswirkungen revolutionär sein“. So sehen zumindest die Analysten des Unternehmensberaters McKinsey Global Institute die Zukunft für den hauchdünnen Kohlenstoff. Doch bisher entwickelt sich Graphen, das Wundermaterial des 21. Jahrhunderts wie es in Wissenschaftlerkreisen bereits genannt wird, eher unbemerkt. In der Theorie wussten die Wissenschaftler bereits seit 1947, dass es möglich sein müsste das Ein-Atom dicke Kohlenstoff-Material herzustellen. Doch erst im Jahr 2003 wurde das Material erstmals produziert, als zwei Professoren an der Universität
      Manchester Graphen-Flocken aus einem Stück Grafit isolieren konnten.

      Das Material stellt eine kristalline Modifikation von Kohlenstoff dar, eine Eigenschaft, die sich das Graphen mit Diamanten und mit Grafit teilt. Vereinfacht gesagt sind alle drei aus Kohlenstoffatomen aufgebaut, die auf verschiedene Art und Weise verbunden sind. Graphit beispielsweise ist aus mehreren Schichten von Kohlenstoffatomen aufgebaut, wobei die einzelnen Lagen in einem hexagonalen Gitter miteinander verbunden sind. Während Graphen dagegen aus einer einzelnen Lage Grafit besteht.

      Dies erklärt noch nicht warum viele Menschen die Entdeckung des Graphens mit großer Begeisterung feiern. Um Investoren von der möglichen Tragweite der Entdeckung des Graphens ein Bild zu geben, müssen die Anwendungsmöglichkeiten des Graphens und das monetäre Gewinnpotenzial des Zukunftsstoffes näher erläutert werden.

      Damit Graphen das Dasein im Labor verlassen und seinen Platz in der Industrie finden kann, muss sich der edle Stoff nicht zuletzt verbilligen. An der Entwicklung neuer günstiger Produktionsmethoden wird mit Hochdruck geforscht. So kann beispielsweise Graphen durch die sogenannte Klebebandmethode gewonnen werden, jedoch eignet sich das nicht für die Produktion in einem größeren Umfang. Daneben können Graphen-Flocken auch mit Hilfe von Gasphasenabscheidung produziert werden.

      Die australische Gesellschaft Talga Resources (ISIN: AU000000TLG7) verwendet einen physiochemischen Prozess in feuchter Umgebung, um aus vergleichsweise reinem Grapfit-Material die einzelnen Graphen-Lagen abzuspalten. Dabei kann Talga auf das eigene Grafit-Material zurückgreifen, dass von den eigenen Liegenschaften nahe der nordschwedischen Stadt Kiruna abgebaut werden kann. Dieses Grafit besitzt die Reinheit und Zusammensetzung, damit der relativ preiswerte Vorgang zur Graphen-Herstellung durchgeführt werden kann.

      Die Liste der Eigenschaften des Graphens ist beeindruckend. Es leitet Elektrizität besser als Kupfer, ist undurchdringlich für Gase, ist mehrfach härter als Stahl, dafür aber sechsmal leichter. Zudem ist Graphen nahezu transparent. Es absorbiert nur zwei Prozent des Lichts. Auch können chemische Bestandteile der Oberfläche des Graphen beigemischt werden und so seine Eigenschaften verändern. Dadurch eröffnen sich für den Stoff der Zukunft in den unterschiedlichsten Bereichen wie Industrie, Transportwesen, Medizin und in der Elektronikbranche verschiedenste Einsatzmöglichkeiten. Energiebranche, Militär, Medizin, Umwelt und Versorgungswirtschaft – dabei sei nur an die Entsalzung von Meerwasser gedacht, könnten, nein dürften Einsatzgebiete für Graphen werden.

      Ein weiteres Beispiel wie Graphen die Zukunft revolutionieren könnte, zeigt die Entdeckung, dass das Material in der Lage ist die Lebensdauer von Lithium-Ionen Batterien zu verdoppeln. Wermutstropfen ist der noch hohe Preis des Graphens. Talga Resources könnte dieses Problem mit seiner Technologie lösen. Und wenn der Markt erst einmal aufgeschlossen ist, dann wird er unaufhaltsam an Breite gewinnen. Ein Ausgangspunkt könnten Anwendungen bei den Olympischen Spielen 2016 in Brasilien sein. Doch auch ohne dieses Großereignis sollte der Triumphzug des Graphens nicht aufzuhalten sein. Die auf Spezialmaterialien spezialisierte Beratungsfirma BCC geht davon aus, dass der Anwendungsmarkt für Graphen 2018 bereits 195 Millionen US-Dollar umfassen dürfte. Danach erwarten die BCC- Analysten eine durchschnittliche jährliche Wachstumsrate von 47 Prozent. In 8 Jahren dürfte der Anwendungsmarkt für Graphen somit bereits 1,3 Milliarden US-Dollar groß sein. Die kleine und damit noch sehr spekulative Talga Resources sollte dabei ihren Platz finden und mit wachsen.

      Amec Foster inks graphene deal, Amec Foster Wheeler has been appointed the preferred engineering partner to Applied Graphene Materials

      www.laboratorytalk.com/407659.article?slref=455879/195772/25

      "Amec Foster Wheeler has been appointed the preferred engineering partner to Applied Graphene Materials.

      The company will provide engineering recommendations to Applied Graphene Materials to support the commercial development of its proprietary process for producing high-purity graphene nanoplatelets.

      An innovator in the development and manufacture of graphene, Applied Graphene Materials was founded in 2010 based on technology that was initially developed at Durham University.

      Graphene nanoplatelets are nanoparticles comprised of small stacks of graphene that can be used to bolster attributes such as strength or stiffness in some composite materials.

      While graphene boasts unique electrical, mechanical and thermal properties, it is difficult to manufacture in large quantities.

      Applied Graphene Materials has established a production facility at the Wilton Science Park on Teesside, which it says is capable of producing high-purity graphene using a continuous and sustainable ’bottom up’ process.

      It is now working with partners to develop commercial applications for graphene, with a focus on materials such as polymers and composites, paints and coatings, and lubricants and oils.

      Amec Foster Wheeler will work with Applied Graphene Materials to refine its conceptual design for a proposed commercial-scale plant, ahead of a Front End Engineering Design (FEED) study.

      A pilot study has already produced high purity graphene nanoplatelets based on sustainable, readily available raw materials, Amec Foster Wheeler said.

      “This is in contrast to other graphene production techniques which rely on the supply of graphite.”

      Nick Shorten, managing director of Amec Foster Wheeler’s Capital Projects & Asset Management business, said: “I’m delighted to bring together the combined skills and expertise of Amec Foster Wheeler to deliver cutting edge solutions to support the commercial development of Applied Graphene Materials’ exciting new technology.” ..."

      Edison Power +Sunvault Energy Create Cost Effective Graphene Reinforced Plastic, for Multi-Purpose Uses
      www.stockhouse.com/news/press-releases/2016/01/11/edison-pow…

      "EDMONTON, ALBERTA--(Marketwired - Jan. 11, 2016) - SUNVAULT ENERGY INC. ("Sunvault") ("the Company") (OTC PINK:SVLT) and Edison Power Company, a Delaware Corporation, announced today that it recently conducted a number of tests on its graphene reinforced plastic technology.

      The Company has created a Graphene Reinforced Plastic that is cost effective and with potential uses that could change the landscape as far as plastics utilization in products is concerned. From automobile parts to enhancing fragile smart phones, this revolutionary material can give products steel like endurance but with the weight, economics and simplicity of plastic. The material has many consumer advantages but in addition there are some protective attributes that are truly impressive.



      In two video presentations the Company first demonstrated the ability of the graphene reinforced plastic to stop a collection of 22 caliber and 45 caliber bullets before demonstrating in the second video presentation the ability to stop the most commonly faced weapon of aggression in the military: the AK47.

      With a thickness of less than a centimeter, the graphene reinforced plastic was only slightly scarred by the .22 and .45 rounds. In a second video presentation, the new plastic composite was set against an AK47 round. The damage to the plastic was more significant, but the round also failed to penetrate, which is encouraging at this early stage of development.

      Further testing has been carried out in accordance with the current standard HOSDB Body Armour Standards for UK Police (2007) Part 3: Knife and Spike Resistance, which is harmonized with the US NIJ OO15 standard.

      These standards define the parameters of the test requirements to classify and determine if a material can be seen as stab proof.

      Following testing the material passed the protection levels as defined in table 7 of the above referenced document. See following link:


      Body Armour Standards

      The weight of the reinforced Graphene plastic is very light and we believe it to be able to be one of the highest performing bullet proof materials in its cost and weight class that exists. Therefore, further testing in respect of the HOSDB and NIJ standards are ongoing in order to seek the bullet proof classification.

      Please see the following videos for these demonstrations on Dr. Robert Murray-Smith's YouTube Channel:

      Video One: Bullet Proof Graphene Plastic - 22 & 45 Test

      Video Two: Bullet Proof Graphene Plastic - AK 47 Round at 50 Yards Test.

      The revolutionary development by the company has attracted quite a bit of attention and Dr. Robert Murray-Smith is conducting additional Edison lab demonstrations and meetings for those interested parties.

      The Company understands the impact this product could have on everything from protective gear for police and the military to upgrading vehicle amour. Not only do automobiles including military vehicles and aircraft stand to benefit from the protective qualities of the graphene reinforced plastic, but that, combined with the economics and the weight advantages of the product, means that other products such as drones will have unique capabilities when coupled with this protective graphene plastic layer. Laptops, Tablets, Cell and Smart Phone outer layers could be almost impermeable to destruction.

      "We are very excited with this technology development," stated Gary Monaghan, Chief Executive Officer for Sunvault Energy. "We believe this technology has wide significant appeal worldwide," he continued.

      - Following on from our first test of the Edison graphene based plastic as a bullet proof plastic we were asked to fire an AK47 at it and this we did - here are the results. Even though this plastic is pretty good at stopping bullets - it has far more uses - car parts being at least one example - but I can think of quite a few more. -

      - This is the CF ABS with 3% graphene enhancement, how to make it, and it versus 303 stainless steel side by side. The plastic is just a bit thinner than the steel, but still has a very surprising result. I show how I crudely make the "puck" with a hotplate and a regular pan.
      7:43 is where the "strength test" is started.-

      Graphene layer could allow solar cells to generate power :eek::eek: , when it rains; Researchers have now introduced a new approach for making an all-weather solar cell that is triggered by both sunlight AND :eek::eek::eek: raindrops
      www.energyharvestingjournal.com/articles/9291/graphene-layer…

      "Solar energy is on the rise. Many technical advances have made solar cells quite efficient and affordable in recent years. A big disadvantage remains in the fact that solar cells produce no power when it's raining. This may change, however: In the journal Angewandte Chemie, Chinese researchers have now introduced a new approach for making an all-weather solar cell that is triggered by both sunlight and raindrops.



      For the conversion of solar energy to electricity, the team from the Ocean University of China (Qingdao) and Yunnan Normal University (Kunming, China) developed a highly efficient dye-sensitized solar cell. In order to allow rain to produce electricity as well, they coated this cell with a whisper-thin film of graphene.

      Graphene is a two-dimensional form of carbon in which the atoms are bonded into a honeycomb arrangement. It can readily be prepared by the oxidation, exfoliation, and subsequent reduction of graphite. Graphene is characterized by its unusual electronic properties: It conducts electricity and is rich in electrons that can move freely across the entire layer (delocalized). In aqueous solution, graphene can bind positively charged ions with its electrons (Lewis acid-base interaction). This property is used in graphene-based processes to remove lead ions and organic dyes from solutions.

      This phenomenon inspired researchers working with Qunwei Tang to use graphene electrodes to obtain power from the impact of raindrops. Raindrops are not pure water. They contain salts that dissociate into positive and negative ions. The positively charged ions, including sodium, calcium, and ammonium ions, can bind to the graphene surface. At the point of contact between the raindrop and the graphene, the water becomes enriched in positive ions and the graphene becomes enriched in delocalized electrons. This results in a double-layer made of electrons and positively charged ions, a feature known as a pseudocapacitor. The difference in potential associated with this phenomenon is sufficient to produce a voltage and current.

      Graphene stretches rubber strength, A team of nanomaterials specialists @the University of Manchester has developed a graphene composite with 50% more elasticity +strength, than polyisoprene +polyurethane rubber

      http://laboratorytalk.com/article/2022451/graphene-stretches…

      "According to Aravind Vijayaraghavan, who led the research, the project emerged after “a call” from the Bill & Melinda Gates Foundation – a grant-making organisation founded by billionaire philanthropist Bill Gates and his wife Melinda.


      Vijayaraghavan said the Foundation wanted to develop "a more desirable condom".

      Our thinking was that if we could make the rubber used in condoms stronger and stretchier, then you could use that to make even thinner condoms which would feel better without breaking

      - Nanomaterials lecturer Aravind Vijayaraghavan -


      “Our thinking was that if we could make the rubber used in condoms stronger and stretchier, then you could use that to make even thinner condoms which would feel better without breaking,” Vijayaraghavan said.

      “Similar arguments can be made for using this material to make better gloves, sportswear, medical devices and so on. We are seeing considerable industrial interest in this area and we hope more companies will want to get involved in the commercial opportunities this research could create,” he added.

      To create the new composite, Vijayaraghavan and research partner Maria Iliut used a form of graphene called graphene oxide, which unlike graphene is stable as a dispersion in water.

      “The [two] rubber materials are also in a form that is stable in water, allowing us to combine them before forming thin films with a process called dip moulding.”

      She said that because the films are so thin, adding strengthening filler was vital.

      “Fortunately, graphene is both the thinnest and strongest material we know of.” "

      Graphene set to change EVERYTHING

      - From 3-D printing to sport, ‘wonder material’ graphene is set to change how we live according to Versarien PLC (LON:VRS) boss and founder Neil Ricketts.
      This year alone Versarien has started to work with former Olympian Kristan Bromley to develop graphene-enhanced skeleton boards, CT Engineering on aero parts and print specialist Absolute Engineering for graphene-based inks.
      Ricketts though, tells Proactive this is just the start as the understanding of these new materials and their uses is still at its very formative stages.
      For Versarien, having completed its IPO, raised funds and on track to break even, it all adds to a great place to be currently he explains. -

      - Haydale Graphene Industries PLC (LON:HAYD) is launching a product that it believes could be a hit in the car-making industry.
      The firm is unveiling its graphene-enhanced poly-lactic acid filaments for 3D printing at a Birmingham trade show next month.
      3D printing lets designers produce components or models directly from computer-aided design software without moulds or tooling.
      Haydale says the market, which is primarily in car-making, could be worth more than US$30bn by 2022.
      Chief executive Ray Gibbs said its product offers potential for faster processing, better performance and higher quality.
      "We think all of this will mean the industry is growing exponentially and will want to take on this material," he said. -

      "So-called “biosensors” are sensors that detect or quantify biomolecules, such as glucose, proteins, or DNA. Biosensing has numerous potential applications in health care, food processing, and environmental control. However, the existing market is largely limited to glucose biosensing. The development of new biosensor technologies could enable the commercial success of biosensors for many different biomolecules, leading to major breakthroughs in diagnostic and personalized medicine.



      Recent advances in polymer science, nanotechnology, and carbon-nanomaterials (graphene in particular) offer a great deal of promise in fulfilling the potential of biosensors. So-called “polymer-graphene nanocomposites” aim to leverage the unique, attractive properties of graphene, such as large surface area and excellent conductivity, by combining them with those of a polymer. As discussed in a recent review by P. Sobolewski et al., a variety of polymers, including intrinsically conducting polymers and bio-based polymers, have been utilized as matrices for graphene, each polymer contributing it’s own unique properties.

      The crucial components of a biosensor that interacts with the target biomolecule are typically other biomolecules, such as antibodies, enzymes, or oligonucleotides. However, these biomolecules are delicate and expensive, limiting mass production. On the other hand, some polymers can be structured by “molecular imprinting”, a process that enables the creation of artificial biorecognition elements in a fast and economic process. As a result, molecular imprinting may be a key technology for enabling biosensors to fulfill their full potential.

      Ultimately, biosensors need to be produced via large-scale synthesis and ideally in an eco-friendly and energy efficient method. From this point of view, a polymer-graphene nanocomposite platform approach is very promising. This strategy would enable a range of biosensors by including variable biorecognition elements, especially those obtained via molecular imprinting. If realized, this approach offers the potential to spearhead the efforts to develop cheap, shelf-stable biosensors for various biomolecules, enabling successful translation to the market."

      Video of the week: Graphene moves speakers out of the box
      www.theengineer.co.uk/video-of-the-week-graphene-moves-speakers-out-of-the-box/

      "Scientists have created a new type of flat speaker that uses a graphene aerogel to create thermoacoustic sound, rather than sound through vibrations.

      The speaker works by rapidly heating and cooling air, and because it doesn’t require a box to create vibrations, it can exist as a flat or even curved surface. Researchers from the Korea Advanced Institute of Science and Technology (KAIST) developed a two-step (freeze-drying and reduction/doping) technique for producing the graphene aerogel. An array of these aerogels was then aligned in a 4×4 configuration to form a 40W speaker. The work, which was supported by the Samsung Research Funding Center for Future Technology and the National Research Foundation of Korea, is described in the journal ACS Applied Materials & Interfaces."




      - Even today’s smallest portable speakers come in some kind of rigid acoustic cavity – that is, in a box. But now, Researchers at the Korea Advanced Institute of Science and Technology report a simple way to fabricate these once-elusive thermoacoustic speakers using graphene. -

      Webinar on growth +characterization of 2D materials, beyond graphene

      - On 3 November (at 3:30-4:30pm GMT), UK-based plasma etch and deposition processing system maker Oxford Instruments and Raman microscopy equipment maker Renishaw are presenting a free webinar focusing on recent advances in the growth of 2D materials beyond graphene and Raman characterization, as well as elucidating the interplay between process engineering and materials characterization.

      Investigation into the physics and technology of graphene in the past decade has triggered research into a large family of similar Van der Waals structures. One such class of materials that is receiving much attention is transition-metal dichalcogenides (TMDCs), which have shown immense potential for both electronics and optoelectronics applications.

      In order to fulfil this potential there needs to be a clear understanding of both the fabrication of 2D materials and the techniques involved in their characterization, says Oxford Instruments.

      The talks to be given in the webinar are:

      'Characterization of 2D materials and heterostructures' by Renishaw's Dr Tim Batten;
      'Deposition of 2D materials and heterostructures' by Oxford Instruments' Dr Ravi Sundaram.

      Ford is about to use graphene in its automobiles, Ford Motor Company gave a paper at the show. The biggest takeaway from that was the statement that it expected to be using graphene extensively in it cars within a couple of years. When questioned by the audience, it said that this will be as early as 2017, when Ford would use it in engine covers for reasons of heat dispersion and mechanical properties. It was also looking at graphene for batteries and energy storage, but that time frame was longer. Ford said that it was getting better than 20% improvements in tensile and flexural strength in body parts with 0.25% w.t. loadings of graphene into nano-composites. It is now investigating graphene uses in smart textiles such as those used for heating and cooling car seats. While the challenge is in the dispersion of graphene, it is obviously a solvable problem. So, there you have an unambiguous statement. Graphene is about to go into Ford automobiles. If one company is at this point in the process you can be sure there are many others on the same cusp. First Graphite is perfectly positioned to supply the graphene, as it told Ford when it came to the FGR booth. Business cards were exchanged

      Improving the world's strongest material, with soybeans

      - REAL superheroes use graphene. -
      https://blog.csiro.au/soybeans-super-scientists-worlds-stron…

      "Graphene is, quite literally, the stuff of superhero comics. It’s made from carbon, is one atom thick, has an optical transparency of 97.3% and also happens to be the strongest material on earth. No wonder it’s already featured as Tony Stark’s new, bulletproof and transparent face-plate in Marvel Comics’ Superior Ironman #2.

      Apart from a superhero’s armour, graphene is actually very useful in real life. It can do anything from improving battery performance in energy devices to developing water purification membranes. We’ve known its potential for a long time, but the major roadblock in commercialising it has always been the high-cost of producing quality, large-scale graphene.

      Traditionally, graphene was grown in a highly-controlled environment with explosive compressed gases, long hours of operation at high temperatures (sometimes 1000°C) and extensive vacuum processing.



      Until NOW.

      Our origin story begins in Lindfield, New South Wales, where our scientists have found a cheaper and faster way to produce graphene. We’ve said goodbye to expensive processes and discovered a unique, low-cost solution to grow graphene using soybean oil and ambient air.

      Alongside The University of Sydney, University of Technology Sydney, and The Queensland University of Technology, we’ve come up with GraphAir technology. The new technology transforms soybean oil – a renewable and natural material – into functional and highly controlled graphene films composed of one to a few layers, all in a single step. The technology reduces the cost of graphene production to a fraction of its current price, making it a whole lot cheaper to produce, while providing many new applications.

      Speaking of applications, it has excellent electronic, mechanical, thermal and optical properties. Further uses range from water filtration to renewable energy, sensors and personalised healthcare and medicine, just to name a few.

      But we haven’t stopped there. The team has also been testing other triglyceride (carbon)-containing precursors – like butter and even waste oils drained from your barbecue – which can also be used to create graphene.

      You heard it RIGHT! In the future you COULD TURN YOUR BARBECUE WASTE INTO THE STRONGEST MATERIAL ON EARTH :eek::eek::eek: , that also cleans the environment. Talk about a win-win situation!

      Now that we’ve figured out low-cost production method for graphene, our now the next step is getting it commercialised ASAP so our smart phones can have better-than-ever battery performance."

These compounds in turn select and bond with specific molecules of interest, including DNA and proteins, or even whole cells. In this image, the treated graphene oxide on the right has oxygen molecules (red) clustered together, making it nearly twice as efficient at capturing cells (green) as the material on the left.

      the FUTURE

      https://investorintel.com/sectors/technology/technology-inte…

      "Graphene is no longer one product, but many. That’s the first thing Dr Ravi Shankar Sundaram said to me when we started our conversation about graphene. Ravi should know, as well as glittering academic credentials he is the market manager for emerging technologies at Oxford Instruments Plasma Technology (OI).

      OI is the company that designs and manufactures equipment that can fabricate, analyse and manipulate matter at the atomic and molecular level. They are also involved in superconducting magnets and quantum computing. High tech indeed.

      Graphene was first isolated in 2004 and won a Nobel Prize for its discoverers in 2010. It is one of the strongest and most thermally and electrically conductive materials in the world. It naturally attracted a lot of attention. Over the past decade graphene has gradually started to move from the laboratory to industry.

      Ravi has played a part in progressing graphene on this journey. Over the past nine years he has been working on graphene and other 2D materials developing ways of making graphene by chemical vapour deposition (CVD) and atomic layer deposition (ALD) methods.

      As well as making the material, he has been involved with developing prototype devices such as sensors and light emitters using these materials. It was no surprise then that he was also involved in the development of the Cambridge Graphene Centre in the UK.

      So, Ravi is well placed to ask about his view of the graphene world. We talk about the use of graphene in carbon fibre composites. Companies such as Haydale are using graphene to enhance carbon fibre composites for aerospace and automotive markets. Adding graphene nanoplatelets can increase the compression strength and impact resistance. This means lighter stronger wings for aircraft, designs that can reduce carbon dioxide emissions.

      Graphene is also finding applications in printed electronics. The Cambridge Graphene Centre recently announced a novel way of creating graphene nanoplatelets as a conductive ink that can be used for printing. This opens the way for cheaper printed electronic circuits for devices such as Radio Frequency Identification (RFID) antennas that are used from everything from passports to electronic tags attached to everyday items that we buy in shops.

      Ravi’s view spans many markets; he is also paying close attention to energy storage. Here graphene is making an impact at the R&D stage because its high surface area makes it ideal for batteries and also for supercapacitors. The promise of graphene is to create energy storage systems with increased range that can be charged in a fraction of the time of current battery technology. Dongxu Optoelectronics has developed a battery called the G-King which reportedly recharges within 15 minutes.

      You will have heard of Lithium-Ion batteries, and will soon be hearing about Carbon-Ion batteries from companies such as ZapnGo who have developed a Carbon-Ion charging pack that will charge an iPhone in just 5 minutes.

      This is all fascinating stuff and here in the present. What about the future? This is where Ravi spends much of his time anticipating the next big things. Remember his first comment that graphene is no longer one product but many. Part of the answer is found in the applications of graphene in all these new products and others.

      What Ravi really points us to are developments in the R&D pipeline. Graphene is just one of a class of new two dimensional (2D) materials. Since the isolation of graphene many other 2D materials have been discovered. These are materials with exotic names such as Molybdenum Disulphide, Boron Nitride and many more.

      2D materials are a new class of compounds for material scientists to play with. Think of them as flat layers that can be sandwiched in different ways to give new combinations of transparency, strength, and conductivity. This is new territory that is opening up to the people who will create the wonderful products of the future. This is why graphene is no longer one product but many. WATCH this space…"

      Nanographenes: Lego bricks, in the nano scale

      http://scienceinpoland.pap.pl/en/news/news%2C27539%2Cnanogra…

      "Nanographenes change their properties depending on the shape and method of joining the rings. The structure affects their interaction with light and chemical molecules. In the future, they may be used in electronics, drug transport and gas storage.

      CROWN, BAGEL, BOWL...

      Nanographenes are carbon compounds composed of properly connected five or six-membered rings. This structure influence their way of interacting with different types of light. Marcin Majewski, PhD student at the University of Wrocław creates and characterises new materials based on these molecules. He specialises in crown-shaped nanographenes.

      "In my work, I synthesize the crown-like nanographenes, i.e. particles of the order of a millionths of a meter, looking like crowns or bagels. Figuratively speaking, I create very small +Lego+ bricks, which I then use to build larger structures" - explained the scientist in an interview with PAP.

      According to Majewski, graphene-like structures can be both flat and spatial. To illustrate them, Marcin Majewski proposes a paper sheet model: if we cut out stripes or polygons from a flat sheet, we can spatially manipulate them by deforming individual fragments. For example, bending all the corners of a square upwards creates a bowl, and bending them alternately (up-down) results in a saddle shape.

      In addition to various shapes, nanographenes can have variable sizes. This factor also affects their properties, the way they interact with the environment. According to Majewski, depending on the shape and size, nanographenes can absorb and emit light in different ways - in both visible and other ranges. This is a desirable property of materials in electronics. Thanks to strictly defined optical parameters, devices for specific applications can be constructed on their basis.

      On the other hand, these materials can be used to interact with smaller molecules that enter the centre of the rim - the so-called "guest-host" interactions. As a result of the project, the researcher obtained a compound that in appropriate conditions binds with chloride ions, such as the ones found in table salt. It is the first hydrocarbon known in the literature that shows the properties of an anion receptor.

      DESIGNING HAND TO HAND WITH SUPERCOMPUTER

      Chemistry of nanographenes is a dynamically developing field, and research in this field is conducted in many of the best research centres in the world. For now, it is mainly basic research, but in the future the gathered knowledge will allow engineers to design new materials more easily and anticipate their desirable properties.

      "Not 15 years has passed since the synthesis and description of graphene, and it already is considered by many to be the future of the whole material chemistry field. It is hundreds of times more durable than steel, it conducts electricity and heat well, it is practically transparent. We can imagine its use in mobile phones, displays, solar panels" - the researcher told PAP.

      His work is largely based on computer modelling. Completely new compounds are developed in the laboratory and it is often difficult to predict how they will behave in reality. Majewski performs synthetic research, that is building compounds and forming them into appropriate shapes, at the Faculty of Chemistry of the University of Wrocław as part of a doctorate in the Organic Synthesis Team under the supervision of Prof. Marcin Stepień. ProfStępień is also responsible for modelling; for this purpose, he uses the resources of supercomputing centres in Poznan and Wroclaw.

      "Computational aspect is very important in modern chemistry. By creating virtual models of future designed molecules and simulating some of their properties we can save a lot of time. It allows us to find out what direction a synthetic project should be going to achieve the goals" - said Majewski.

      He noted that this is a complex process. First, he models his nanographene compound, then he figures out with what smaller elements - the mentioned "Lego" bricks - it can be built. Then he must make them in the laboratory and then work out how the individual bricks should be connected.

      FROM A SCIENTIFIC CURIOSITY - A COMMERCIAL PRODUCT

      The researcher admitted that there are many dead ands in his work, and the characterization of the obtained material usually requires cooperation with specialists in various fields of science, often also from other research centres. In the described project, some of the calculations, as well as description of certain electrochemical and luminescent properties of the obtained compounds was possible thanks to the researchers from the Yonsei University in Seoul (South Korea).

      "The equipment available at the university allows us to study the magnetic properties of compounds, among other things. The basic technique for me - as an organic chemist - is nuclear magnetic resonance (NMR) spectroscopy, a modified version of which we know from hospitals under the name of magnetic resonance. Our spectrometer is designed to study a variety of chemical molecules. UV-Vis spectroscopy that tests the interaction of these compounds with visible and ultraviolet light is also helpful" - said the chemist.

      Although graphene is still not cheap material, scientists and engineers can buy it without a problem. From a scientific curiosity it has become a commercially available product. However, as the researcher emphasised, laboratory scale production, which is many times smaller than industrial one, requires considerable resources, including laboratory equipment and chemical reagents. In this context, scientific grants become the basic form of research funding.

      Marcin Majewski received funds from the National Science Centre and a START scholarship from the Foundation for Polish Science. He emphasised that in modern technologies the cost is considered differently and often one successful investment at the implementation level is enough to cover the costs of ten other, non-commercialised projects.

      In September 2015, world leaders gathered at a historic UN summit to adopt the Sustainable Development Goals (SDGs). These are 17 ambitious targets and indicators that help guide and coordinate governments and international organizations to alleviate global problems. For example, SDG 3 is to “ensure healthy lives and promote well-being for all at all ages.” Others include access to clean water, reducing the effects of climate change, and affordable healthcare.

      If you think these goals might be difficult to meet, you’re right. Reports show progress is lacking in many of the 17 categories, implying they may not be met by the target date of 2030. However, paired with progress in social and political arenas, advances in science and technology could be a key accelerant to progress too.

      Just one example? Graphene, a futuristic material with a growing set of potential applications.

      Graphene is comprised of tightly-knit carbon atoms arranged into a sheet only one atom thick. This makes it the thinnest substance ever made, yet it is 200 times stronger than steel, flexible, stretchable, self-healing, transparent, more conductive than copper, and even superconductive. A square meter of graphene weighing a mere 0.0077 grams can support four kilograms. It is a truly remarkable material—but this isn’t news to science and tech geeks.

      Headlines touting graphene as the next wonder material have been a regular occurrence in the last decade, and the trip from promise to practicality has felt a bit lengthy. But that’s not unexpected; it can take time for new materials to go mainstream. Meanwhile, the years researching graphene have yielded a long list of reasons to keep at it.

      Since first isolated in 2004 at the University of Manchester—work that led to a Nobel Prize in 2010— researchers all over the world have been developing radical ways to use and, importantly, make graphene. Indeed, one of the primary factors holding back widespread adoption has been how to produce graphene at scale on the cheap, limiting it to the lab and a handful of commercial applications. Fortunately, there have been advances toward mass production.

      Last year, for example, a team from Kansas State University used explosions to synthesize large quantities of graphene. Their method is simple: Fill a chamber with acetylene or ethylene gas and oxygen. Use a vehicle spark plug to create a contained detonation. Collect the graphene that forms afterward. Acetylene and ethylene are composed of carbon and hydrogen, and when the hydrogen is consumed in the explosion, the carbon is free to bond with itself, forming graphene. This method is efficient because all it takes is a single spark.

      Whether this technique will usher in the graphene revolution, as some have claimed, remains to be seen. What’s more certain is there will be no shortage of problems solved when said revolution arrives. Here’s a look at the ways today’s research suggests graphene may help the UN meet its ambitious development goals.

      Clean Water

      SDG 6 is to “ensure availability and sustainable management of water and sanitation for all.” As of now, the UN estimates that “water scarcity affects more than 40 percent of the global population and is projected to rise.”

      Graphene-based filters could very well be the solution. Jiro Abraham from the University of Manchester helped develop scalable graphene oxide sieves to filter seawater. He claims, “The developed membranes are not only useful for desalination, but the atomic scale tunability of the pore size also opens new opportunity to fabricate membranes with on-demand filtration capable of filtering out ions according to their sizes.”

      Furthermore, researchers from Monash University and the University of Kentucky have developed graphene filters that can filter out anything larger than one nanometer. They say their filters “could be used to filter chemicals, viruses, or bacteria from a range of liquids. It could be used to purify water, dairy products or wine, or in the production of pharmaceuticals.”

      Carbon Emissions

      SDG 13 focuses on taking “urgent action to combat climate change and its impacts.”

      Of course, one of the main culprits behind climate change is the excessive amount of carbon dioxide being emitted into the atmosphere. Graphene membranes have been developed that can capture these emissions.

      Researchers at the University of South Carolina and Hanyang University in South Korea independently developed graphene-based filters that can be used to separate unwanted gases from industrial, commercial, and residential emissions. Henry Foley at the University of Missouri has claimed these discoveries are “something of a holy grail.”

      With these, the world might be able to stem the rise of CO2 in the atmosphere, especially now that we have crossed the important 400 parts per million threshold.

      Healthcare

      Many around the world do not have access to adequate healthcare, but graphene may have an impact here as well.

      First of all, graphene’s high mechanical strength makes it a perfect material for replacing body parts like bones, and because of its conductivity it can replace body parts that require electrical current, like organs and nerves. In fact, researchers at the Michigan Technological University are working on using 3D printers to print graphene-based nerves, and this team is developing biocompatible materials using graphene to conduct electricity.



      Graphene can also be used to make biomedical sensors for detecting diseases, viruses, and other toxins. Because every atom of graphene is exposed, due to it being only one atom thick, sensors can be far more sensitive. Graphene oxide sensors, for example, could detect toxins at levels 10 times less than today’s sensors. These sensors could be placed on or under the skin and provide doctors and researchers with vast amounts of information.

      Chinese scientists have even created a sensor that can detect a single cancerous cell. Further, scientists at the University of Manchester report graphene oxide can hunt and neutralize cancer stem cells.

      Infrastructure

      SDG 9 is to “build resilient infrastructure, promote inclusive and sustainable industrialization and foster innovation.” Graphene-enhanced composites and other building materials could bring us closer to meeting this goal.

      Recent research shows that the more graphene is added, the better the composite becomes. This means graphene can be added to building materials like concrete, aluminum, etc., which will allow for stronger and lighter materials.

      Resins are also getting better thanks to the addition of graphene. Research by Graphene Flagship, the EU’s billion-euro project to further graphene research, and their partner Avanzare suggests “graphene enhances the functionality of the resin, combining graphene’s electrical conductivity and mechanical strength with excellent corrosion resistance.” Some uses for this are making pipes and storage tanks corrosion-resistant, and making stronger adhesives.

      Energy

      SDG 7 is to “ensure access to affordable, reliable, sustainable and modern energy for all.” Because of its light weight, conductivity, and tensile strength, graphene may make sustainable energy cheaper and more efficient.

      For example, graphene composites can be used to create more versatile solar panels. Researchers at MIT say, “The ability to use graphene…is making possible truly flexible, low-cost, transparent solar cells that can turn virtually any surface into a source of electric power.”

      We’ll also be able to build bigger and lighter wind turbines thanks to graphene composites.

      Further, graphene is already being used to enhance traditional lithium-ion batteries, which are the batteries commonly found in consumer electronics. Research is also being done into graphene aerogels for energy storage and supercapacitors. All of these will be essential for large-scale storage of renewable energy.

      Over the next decade, graphene is likely to find more and more uses out in the real world, not only helping the UN and member states meet the SDGs, but enhancing everything from touch screens to MRI machines and from transistors to unknown uses as a superconductor.

      New research is being published and new patents being filed regularly, so keep an eye out for this amazing material.

      Graphene on toast, aaaaanyone???????????
      (MAY new class of electronics)


      - Rice University scientists who introduced laser-induced graphene (LIG) have enhanced their technique to produce what may become a new class of edible electronics. The Rice lab of chemist James Tour, which once turned Girl Scout cookies into graphene, is investigating ways to write graphene patterns onto food and other materials with a laser. The process is an extension of the Tour lab's contention that anything with the proper carbon content can be turned into graphene. In recent years, the lab has developed and expanded upon its method to make graphene foam by using a commercial laser to transform the top layer of an inexpensive polymer film.

      Yale-NUS Scientist and Collaborators Solve Open Theoretical Problem on Electron Interactions
      Thu, 08/09/2018 - 3:25pm 1 Comment
      by YALE-NUS College
      The open problem was what controlled the velocity of the electron liquid (shown as a wavy waterfront). The findings show that it is the frozen antiferromagnetism on the honeycomb lattice that sets this velocity by slowing it down as the two interact.

      Yale-NUS Associate Professor of Science (Physics) Shaffique Adam is the lead author for a recent work that describes a model for electron interaction in Dirac materials, a class of materials that includes graphene and topological insulators, solving a 65-year-old open theoretical problem in the process. The discovery will help scientists better understand electron interaction in new materials, paving the way for developing advanced electronics such as faster processors. The work was published in the peer-reviewed academic journal Science on 10 August 2018.

      Electron behaviour is governed by two major theories - the Coulomb's law and the Fermi liquid theory. According to Fermi liquid theory, electrons in a conductive material behave like a liquid - their "flow" through a material is what causes electricity. For Dirac fermions, the Fermi liquid theory breaks down if the Coulomb force between the electrons crosses a certain threshold: the electrons "freeze" into a more rigid pattern which inhibits the "flow" of electrons, causing the material to become non-conductive.

      For more than 65 years, this problem was relegated to a mathematical curiosity, because Dirac materials where the Coulomb threshold was reached had never been made. Today, however, we routinely make use of quantum materials for applications in technology, such as transistors in processors, where the electrons are engineered to have desired properties, including those which push the Coulomb force past this threshold. But the effects of strong electron-electron interaction can only be seen in very clean samples.

      In the work immediately following his PhD, Assoc Prof Adam proposed a model to describe experimentally available Dirac materials that were "very dirty" (contains a lot of impurities). However, in the years that followed, newer and cleaner materials have been made, and this previous theory no longer worked.

      In this latest work titled, "The role of electron-electron interactions in two-dimensional Dirac fermions", Assoc Prof Adam and his research team have developed a model which explains electron interactions past the Coulomb threshold in all Dirac materials by using a combination of numerical and analytical techniques.

      In this research, the team designed a method to study the evolution of physical observables in a controllable manner and used it to address the competing effects of short-range and long-range parts in models of the Coulomb interaction. The researchers discovered that the velocity of electrons (the "flow" speed) in a material could decrease if the short-range interaction that favoured the insulating, "frozen" state dominated. However, the velocity of electrons could be enhanced by the long-range component that favoured the conducting, "liquid" state. With this discovery, scientists can better understand long-range interactions of electrons non-perturbatively - something that previous theories were not able to explain - and serves as useful predictors for experiments exploring the long-range-interaction divergence in Dirac electrons when they transition between conducting to insulating phases.

      This improved understanding in the evolution of the electron velocity during the phase transition paves the way to help scientists develop low heat dissipation devices for electronics. Assoc Prof Adam explains, "The higher the electron velocity, the faster transistors can be switched on and off. However, this faster processor performance comes at the price of increased power leakage, which produces extra heat, and this heat will counteract the performance increase granted by the faster switching. Our findings on electron velocity behaviour will help scientists engineer devices that are capable of faster switching but low power leakage."

      Assoc Prof Adam adds, "Because the mechanism in our new model harnesses the Coulomb force, it would cost less energy per switch compared to mechanisms available currently. Understanding and applying our new model could POTENTIALLY usher in a new generation of technology.""
