Graphene Flagship high points

The European Union’s Graphene Flagship project has provided a series of highlights in place of an overview for the project’s ramp-up phase (in 2013 the Graphene Flagship was announced as one of two winners of a science competition, the other winner was the Human Brain Project, with two prizes of 1B Euros for each project). Here are the highlights from the April 19, 2016 Graphene Flagship press release,

Graphene and Neurons – the Best of Friends

Flagship researchers have shown that it is possible to interface untreated graphene with neuron cells whilst maintaining the integrity of these vital cells [1]. This result is a significant first step towards using graphene to produce better deep brain implants which can both harness and control the brain.

This paper emerged from the Graphene Flagship Work Package Health and Environment. Prof. Prato, the WP leader from the University of Trieste in Italy, commented that “We are currently involved in frontline research in graphene technology towards biomedical applications, exploring the interactions between graphene nano- and micro-sheets with the sophisticated signalling machinery of nerve cells. Our work is a first step in that direction.”

Pressure Sensing with Graphene: Quite a Squeeze

The Graphene Flagship developed a small, robust, highly efficient squeeze film pressure sensor [2]. Pressure sensors are present in most mobile handsets and by replacing current sensor membranes with a graphene membrane they allow the sensor to decrease in size and significantly increase its responsiveness and lifetime.

Discussing this work which emerged from the Graphene Flagship Work Package Sensors is the paper’s lead author, Robin Dolleman from the Technical University of Delft in The Netherlands “After spending a year modelling various systems the idea of the squeeze-film pressure sensor was formed. Funding from the Graphene Flagship provided the opportunity to perform the experiments and we obtained very good results. We built a squeeze-film pressure sensor from 31 layers of graphene, which showed a 45 times higher response than silicon based devices, while reducing the area of the device by a factor of 25. Currently, our work is focused on obtaining similar results on monolayer graphene.”

Image caption: A graphene nanoribbon was anchored at the tip of a atomic force microscope and dragged over a gold surface. The observed friction force was extremely low.

Research done within the Graphene Flagship, has observed the onset of superlubricity in graphene nanoribbons sliding on a surface, unravelling the role played by ribbon size and elasticity [3]. This important finding opens up the development potential of nanographene frictionless coatings. This research lead by the Graphene Flagship Work Package Nanocomposites also involved researchers from Work Package Materials and Work Package Health and the Environment, a shining example of the inter-disciplinary, cross-collaborative approach to research undertaken within the Graphene Flagship. Discussing this further is the Work Package Nanocomposites Leader, Dr Vincenzo Palermo from CNR National Research Council, Italy “Strengthening the collaboration and interactions with other Flagship Work Packages created added value through a strong exchange of materials, samples and information”.

​Graphene Paddles Forward

Work undertaken within the Graphene Flagship saw Spanish automotive interiors specialist, and Flagship partner, Grupo Antolin SA work in collaboration with Roman Kayaks to develop an innovative kayak that incorporates graphene into its thermoset polymeric matrices. The use of graphene and related materials results in a significant increase in both impact strength and stiffness, improving the resistance to breakage in critical areas of the boat. Pushing the graphene canoe well beyond the prototype demonstration bubble, Roman Kayaks chose to use the K-1 kayak in the Canoe Marathon World Championships held in September in Gyor, Hungary where the Graphene Canoe was really put through its paces.

Talking further about this collaboration from the Graphene Flagship Work Package Production is the WP leader, Dr Ken Teo from Aixtron Ltd., UK “In the Graphene Flagship project, Work Package Production works as a technology enabler for real-world applications. Here we show the worlds first K-1 kayak (5.2 meters long), using graphene related materials developed by Grupo Antolin. We are very happy to see that graphene is creating value beyond traditional industries.” 

​Graphene Production – a Kitchen Sink Approach

Researchers from the Graphene Flagship have devised a way of producing large quantities of graphene by separating graphite flakes in liquids with a rotating tool that works in much the same way as a kitchen blender [4]. This paves the way to mass production of high quality graphene at a low cost.

The method was produced within the Graphene Flagship Work Package Production and is talked about further here by the WP deputy leader, Prof. Jonathan Coleman from Trinity College Dublin, Ireland “This technique produced graphene at higher rates than most other methods, and produced sheets of 2D materials that will be useful in a range of applications, from printed electronics to energy generation.”

Flexible Displays – Rolled Up in your Pocket

Working with researchers from the Graphene Flagship the Flagship partner, FlexEnable, demonstrated the world’s first flexible display with graphene incorporated into its pixel backplane. Combined with an electrophoretic imaging film, the result is a low-power, durable display suitable for use in many and varied environments.

Emerging from the Graphene Flagship Work Package Flexible Electronics this illustrates the power of collaboration.  Talking about this is the WP leader Dr Henrik Sandberg from the VTT Technical Research Centre of Finland Ltd., Finland “Here we show the power of collaboration. To deliver these flexible demonstrators and prototypes we have seen materials experts working together with components manufacturers and system integrators. These devices will have a potential impact in several emerging fields such as wearables and the Internet of Things.”

​Fibre-Optics Data Boost from Graphene

A team of researches from the Graphene Flagship have demonstrated high-performance photo detectors for infrared fibre-optic communication systems based on wafer-scale graphene [5]. This can increase the amount of information transferred whilst at the same time make the devises smaller and more cost effective.

Discussing this work which emerged from the Graphene Flagship Work Package Optoelectronics is the paper’s lead author, Daniel Schall from AMO, Germany “Graphene has outstanding properties when it comes to the mobility of its electric charge carriers, and this can increase the speed at which electronic devices operate.”

​Rechargeable Batteries with Graphene

A number of different research groups within the Graphene Flagship are working on rechargeable batteries. One group has developed a graphene-based rechargeable battery of the lithium-ion type used in portable electronic devices [6]. Graphene is incorporated into the battery anode in the form of a spreadable ink containing a suspension of graphene nanoflakes giving an increased energy efficiency of 20%. A second group of researchers have demonstrated a lithium-oxygen battery with high energy density, efficiency and stability [7]. They produced a device with over 90% efficiency that may be recharged more than 2,000 times. Their lithium-oxygen cell features a porous, ‘fluffy’ electrode made from graphene together with additives that alter the chemical reactions at work in the battery.

Graphene Flagship researchers show how the 2D material graphene can improve the energy capacity, efficiency and stability of lithium-oxygen batteries.

Both devices were developed in different groups within the Graphene Flagship Work Package Energy and speaking of the technology further is Prof. Clare Grey from Cambridge University, UK “What we’ve achieved is a significant advance for this technology, and suggests whole new areas for research – we haven’t solved all the problems inherent to this chemistry, but our results do show routes forward towards a practical device”.

Graphene – What and Why?

Graphene is a two-dimensional material formed by a single atom-thick layer of carbon, with the carbon atoms arranged in a honeycomb-like lattice. This transparent, flexible material has a number of unique properties. For example, it is 100 times stronger than steel, and conducts electricity and heat with great efficiency.

A number of practical applications for graphene are currently being developed. These include flexible and wearable electronics and antennas, sensors, optoelectronics and data communication systems, medical and bioengineering technologies, filtration, super-strong composites, photovoltaics and energy storage.

Graphene and Beyond

The Graphene Flagship also covers other layered materials, as well as hybrids formed by combining graphene with these complementary materials, or with other materials and structures, ranging from polymers, to metals, cement, and traditional semiconductors such as silicon. Graphene is just the first of thousands of possible single layer materials. The Flagship plans to accelerate their journey from laboratory to factory floor.

Especially exciting is the possibility of stacking monolayers of different elements to create materials not found in nature, with properties tailored for specific applications. Such composite layered materials could be combined with other nanomaterials, such as metal nanoparticles, in order to further enhance their properties and uses.​

Graphene – the Fruit of European Scientific Excellence

Europe, North America and Asia are all active centres of graphene R&D, but Europe has special claim to be at the centre of this activity. The ground-breaking experiments on graphene recognised in the award of the 2010 Nobel Prize in Physics were conducted by European physicists, Andre Geim and Konstantin Novoselov, both at Manchester University. Since then, graphene research in Europe has continued apace, with major public funding for specialist centres, and the stimulation of academic-industrial partnerships devoted to graphene and related materials. It is European scientists and engineers who as part of the Graphene Flagship are closely coordinating research efforts, and accelerating the transfer of layered materials from the laboratory to factory floor.

For anyone who would like links to the published papers, you can check out an April 20, 2016 news item featuring the Graphene Flagship highlights on Nanowerk.

With over 150 partners from over 20 countries, the European Union’s Graphene Flagship research initiative unveils its work package devoted to biomedical technologies

An April 11, 2016 news item on Nanowerk announces the Graphene Flagship’s latest work package,

With a budget of €1 billion, the Graphene Flagship represents a new form of joint, coordinated research on an unprecedented scale, forming Europe’s biggest ever research initiative. It was launched in 2013 to bring together academic and industrial researchers to take graphene from the realm of academic laboratories into European society in the timeframe of 10 years. The initiative currently involves over 150 partners from more than 20 European countries. The Graphene Flagship, coordinated by Chalmers University of Technology (Sweden), is implemented around 15 scientific Work Packages on specific science and technology topics, such as fundamental science, materials, health and environment, energy, sensors, flexible electronics and spintronics.

Today [April 11, 2016], the Graphene Flagship announced in Barcelona the creation of a new Work Package devoted to Biomedical Technologies, one emerging application area for graphene and other 2D materials. This initiative is led by Professor Kostas Kostarelos, from the University of Manchester (United Kingdom), and ICREA Professor Jose Antonio Garrido, from the Catalan Institute of Nanoscience and Nanotechnology (ICN2, Spain). The Kick-off event, held in the Casa Convalescència of the Universitat Autònoma de Barcelona (UAB), is co-organised by ICN2 (ICREA Prof Jose Antonio Garrido), Centro Nacional de Microelectrónica (CNM-IMB-CSIC, CIBER-BBN; CSIC Tenured Scientist Dr Rosa Villa), and Institut d’Investigacions Biomèdiques August Pi i Sunyer (IDIBAPS; ICREA Prof Mavi Sánchez-Vives).

An April 11, 2016 ICN2 press release, which originated the news item, provides more detail about the Biomedical Technologies work package and other work packages,

The new Work Package will focus on the development of implants based on graphene and 2D-materials that have therapeutic functionalities for specific clinical outcomes, in disciplines such as neurology, ophthalmology and surgery. It will include research in three main areas: Materials Engineering; Implant Technology & Engineering; and Functionality and Therapeutic Efficacy. The objective is to explore novel implants with therapeutic capacity that will be further developed in the next phases of the Graphene Flagship.

The Materials Engineering area will be devoted to the production, characterisation, chemical modification and optimisation of graphene materials that will be adopted for the design of implants and therapeutic element technologies. Its results will be applied by the Implant Technology and Engineering area on the design of implant technologies. Several teams will work in parallel on retinal, cortical, and deep brain implants, as well as devices to be applied in the periphery nerve system. Finally, The Functionality and Therapeutic Efficacy area activities will centre on development of devices that, in addition to interfacing the nerve system for recording and stimulation of electrical activity, also have therapeutic functionality.

Stimulation therapies will focus on the adoption of graphene materials in implants with stimulation capabilities in Parkinson’s, blindness and epilepsy disease models. On the other hand, biological therapies will focus on the development of graphene materials as transport devices of biological molecules (nucleic acids, protein fragments, peptides) for modulation of neurophysiological processes. Both approaches involve a transversal innovation environment that brings together the efforts of different Work Packages within the Graphene Flagship.

A leading role for Barcelona in Graphene and 2D-Materials

The kick-off meeting of the new Graphene Flagship Work Package takes place in Barcelona because of the strong involvement of local institutions and the high international profile of Catalonia in 2D-materials and biomedical research. Institutions such as the Catalan Institute of Nanoscience and Nanotechnology (ICN2) develop frontier research in a supportive environment which attracts talented researchers from abroad, such as ICREA Research Prof Jose Antonio Garrido, Group Leader of the ICN2 Advanced Electronic Materials and Devices Group and now also Deputy Leader of the Biomedical Technologies Work Package. Until summer 2015 he was leading a research group at the Technische Universität München (Germany).

Further Graphene Flagship events in Barcelona are planned; in May 2016 ICN2 will also host a meeting of the Spintronics Work Package. ICREA Prof Stephan Roche, Group Leader of the ICN2 Theoretical and Computational Nanoscience Group, is the deputy leader of this Work Package led by Prof Bart van Wees, from the University of Groningen (The Netherlands). Another Work Package, on optoelectronics, is led by Prof Frank Koppens from the Institute of Photonic Sciences (ICFO, Spain), with Prof Andrea Ferrari from the University of Cambridge (United Kingdom) as deputy. Thus a number of prominent research institutes in Barcelona are deeply involved in the coordination of this European research initiative.

Kostas Kostarelos, the leader of the Biomedical Technologies Graphene Flagship work package, has been mentioned here before in the context of his blog posts for The Guardian science blog network (see my Aug. 7, 2014 post for a link to his post on metaphors used in medicine).

Tempest in a teapot or a sign of things to come? UK’s National Graphene Institute kerfuffle

A scandal-in-the-offing, intellectual property, miffed academics, a chortling businessman, graphene, and much more make this a fascinating story.

Before launching into the main attractions, those unfamiliar with the UK graphene effort might find this background informal useful. Graphene, was first isolated at the University of Manchester in 2004 by scientists Andre Geim* and Konstantin Novoselov, Russian immigrants, both of whom have since become Nobel laureates and knights of the realm. The excitement in the UK and elsewhere is due to graphene’s extraordinary properties which could lead to transparent electronics, foldable/bendable electronics, better implants, efficient and inexpensive (they hope) water filters, and more. The UK government has invested a lot of money in graphene as has the European Union (1B Euros in the Graphene Flagship) in the hope that huge economic benefits will be reaped.

Dexter Johnson’s March 15, 2016 posting on his Nanoclast blog (on the IEEE [Institute for Electrical and Electronics Engineers] website) provides details about the situation (Note: Links have been removed),

A technology that, a year ago, was being lauded as the “first commercially viable consumer product” using graphene now appears to be caught up in an imbroglio over who owns its intellectual property rights. The resulting controversy has left the research institute behind the technology in a bit of a public relations quagmire.

The venerable UK publication The Sunday Times reported this week on what appeared to be a mutiny occurring at the National Graphene Institute (NGI) located at the University of Manchester. Researchers at the NGI had reportedly stayed away from working at the institute’s gleaming new $71 million research facility over fears that their research was going to end up in the hands of foreign companies, in particular a Taiwan-based company called BGT Materials.

The “first commercially viable consumer product” noted in Dexter’s posting was a graphene-based lightbulb which was announced by the NGI to much loud crowing in March 2015 (see my March 30, 2015 posting). The company producing the lightbulb was announced as “… Graphene Lighting PLC is a spin-out based on a strategic partnership with the National Graphene Institute (NGI) at The University of Manchester to create graphene applications.” There was no mention of BGT.

Dexter describes the situation from the BGT perspective (from his March 15, 2016 posting), Note: Links have been removed,

… BGT did not demur when asked by  the Times whether it owned the technology. In fact, Chung Ping Lai, BGT’s CEO, claimed it was his company that had invented the technology for the light bulb and not the NGI. The Times report further stated that Lai controls all the key patents and claims to be delighted with his joint venture with the university. “I believe in luck and I have had luck in Manchester,” Lai told the Times.

With companies outside the UK holding majority stakes in the companies spun out of the NGI—allowing them to claim ownership of the technologies developed at the institute—one is left to wonder what was the purpose of the £50 million (US $79 million) earmarked for graphene research in the UK more than four years ago? Was it to develop a local economy based around graphene—a “Graphene Valley”, if you will? Or was it to prop up the local construction industry through the building of shiny new buildings that reportedly few people occupy? That’s the charge leveled by Andre Geim, Nobel laureate for his discovery of graphene, and NGI’s shining star. Geim reportedly described the new NGI building as: “Money put in the British building industry rather than science.”

Dexter ends his March 15, 2016 posting with an observation  that will seem familiar to Canadians,

Now, it seems the government’s eagerness to invest in graphene research—or at least, the facilities for conducting that research—might have ended up bringing it to the same place as its previous lack of investment: the science is done in the UK and the exploitation of the technology is done elsewhere.

The March 13, 2016 Sunday Times article [ETA on April 3, 2016: This article is now behind a paywall] by Tom Harper, Jon Ungoed-Thomas and Michael Sheridan, which seems to be the source of Dexter’s posting, takes a more partisan approach,

ACADEMICS are boycotting a top research facility after a company linked to China was given access to lucrative confidential material from one of Britain’s greatest scientific breakthroughs.

Some scientists at Manchester University working on graphene, a wonder substance 200 times stronger than steel, refuse to work at the new £61m national institution, set up to find ways to exploit the material, amid concerns over a deal struck between senior university management and BGT Materials.

The academics are concerned that the National Graphene Institute (NGI), which was opened last year by George Osborne, the chancellor, and forms one of the key planks of his “northern powerhouse” industrial strategy, does not have the necessary safeguards to protect their confidential research, which could revolutionise the electronics, energy, health and building industries.

BGT, which is controlled by a Taiwanese businessman, subsequently agreed to work with a Chinese manufacturing company and university to develop similar graphene technology.

BGT says its work in Manchester has been successful and it is “offensive” and “untrue” to suggest that it would unfairly use intellectual property. The university say there is no evidence “whatsoever” of unfair use of confidential information. Manchester says it is understandable that some scientists are cautious about the collaborative environment of the new institute. But one senior academic said the arrangement with BGT had caused the university’s graphene research to descend into “complete anarchy”.

The academic said: “The NGI is a national facility, and why should we use it for a company, which is not even an English [owned] company? How much [intellectual property] is staying in England and how much is going to Taiwan?”

The row highlights concerns that the UK has dawdled in developing one of its greatest discoveries. Nearly 50% of ­graphene-related patents have been filed in China, and just 1% in Britain.

Manchester signed a £5m “research collaboration agreement” with BGT Materials in October 2013. Although the company is controlled by a Taiwanese businessman, Chung-ping Lai, the university does have a 17.5% shareholding.

Manchester claimed that the commercial deal would “attract a significant number of jobs to the city” and “benefit the UK economy”.

However, an investigation by The Sunday Times has established:

Only four jobs have been created as a result of the deal and BGT has not paid the full £5m due under the agreement after two projects were cancelled.

Pictures sent to The Sunday Times by a source at the university last month show that the offices at the NGI [National Graphene Institute], which can accommodate 120 staff, were deserted.

British-based businessmen working with graphene have also told The Sunday Times of their concerns about the institute’s information security. Tim Harper, a Manchester-based graphene entrepreneur, said: “We looked at locating there [at the NGI] but we take intellectual property extremely seriously and it is a problem locating in such a facility.

“If you don’t have control over your computer systems or the keys to your lab, then you’ve got a problem.”

I recommend reading Dexter’s post and the Sunday Times article as they provide some compelling insight into the UK situation vis à vis nanotechnology, science, and innovation.

Graphene and neurons in a UK-Italy-Spain collaboration

There’s been a lot of talk about using graphene-based implants in the brain due to the material’s flexibility along with its other properties. A step forward has been taking according to a Jan. 29, 2016 news item on phys.org,

Researchers have successfully demonstrated how it is possible to interface graphene – a two-dimensional form of carbon – with neurons, or nerve cells, while maintaining the integrity of these vital cells. The work may be used to build graphene-based electrodes that can safely be implanted in the brain, offering promise for the restoration of sensory functions for amputee or paralysed patients, or for individuals with motor disorders such as epilepsy or Parkinson’s disease.

A Jan. 29, 2016 Cambridge University press release (also on EurekAlert), which originated the news item, provides more detail,

Previously, other groups had shown that it is possible to use treated graphene to interact with neurons. However the signal to noise ratio from this interface was very low. By developing methods of working with untreated graphene, the researchers retained the material’s electrical conductivity, making it a significantly better electrode.

“For the first time we interfaced graphene to neurons directly,” said Professor Laura Ballerini of the University of Trieste in Italy. “We then tested the ability of neurons to generate electrical signals known to represent brain activities, and found that the neurons retained their neuronal signalling properties unaltered. This is the first functional study of neuronal synaptic activity using uncoated graphene based materials.”

Our understanding of the brain has increased to such a degree that by interfacing directly between the brain and the outside world we can now harness and control some of its functions. For instance, by measuring the brain’s electrical impulses, sensory functions can be recovered. This can be used to control robotic arms for amputee patients or any number of basic processes for paralysed patients – from speech to movement of objects in the world around them. Alternatively, by interfering with these electrical impulses, motor disorders (such as epilepsy or Parkinson’s) can start to be controlled.

Scientists have made this possible by developing electrodes that can be placed deep within the brain. These electrodes connect directly to neurons and transmit their electrical signals away from the body, allowing their meaning to be decoded.

However, the interface between neurons and electrodes has often been problematic: not only do the electrodes need to be highly sensitive to electrical impulses, but they need to be stable in the body without altering the tissue they measure.

Too often the modern electrodes used for this interface (based on tungsten or silicon) suffer from partial or complete loss of signal over time. This is often caused by the formation of scar tissue from the electrode insertion, which prevents the electrode from moving with the natural movements of the brain due to its rigid nature.

Graphene has been shown to be a promising material to solve these problems, because of its excellent conductivity, flexibility, biocompatibility and stability within the body.

Based on experiments conducted in rat brain cell cultures, the researchers found that untreated graphene electrodes interfaced well with neurons. By studying the neurons with electron microscopy and immunofluorescence the researchers found that they remained healthy, transmitting normal electric impulses and, importantly, none of the adverse reactions which lead to the damaging scar tissue were seen.

According to the researchers, this is the first step towards using pristine graphene-based materials as an electrode for a neuro-interface. In future, the researchers will investigate how different forms of graphene, from multiple layers to monolayers, are able to affect neurons, and whether tuning the material properties of graphene might alter the synapses and neuronal excitability in new and unique ways. “Hopefully this will pave the way for better deep brain implants to both harness and control the brain, with higher sensitivity and fewer unwanted side effects,” said Ballerini.

“We are currently involved in frontline research in graphene technology towards biomedical applications,” said Professor Maurizio Prato from the University of Trieste. “In this scenario, the development and translation in neurology of graphene-based high-performance biodevices requires the exploration of the interactions between graphene nano- and micro-sheets with the sophisticated signalling machinery of nerve cells. Our work is only a first step in that direction.”

“These initial results show how we are just at the tip of the iceberg when it comes to the potential of graphene and related materials in bio-applications and medicine,” said Professor Andrea Ferrari, Director of the Cambridge Graphene Centre. “The expertise developed at the Cambridge Graphene Centre allows us to produce large quantities of pristine material in solution, and this study proves the compatibility of our process with neuro-interfaces.”

The research was funded by the Graphene Flagship [emphasis mine],  a European initiative which promotes a collaborative approach to research with an aim of helping to translate graphene out of the academic laboratory, through local industry and into society.

There are a couple things I found a bit odd about this project. First, all of the funding is from the Graphene Flagship initiative. I was expecting to see at least some funding from the European Union’s other mega-sized science initiative, the Human Brain Project. Second, there was no mention of Spain nor were there any quotes from the Spanish researchers. For the record, the Spanish institutions represented were: University of Castilla-La Mancha, Carbon Nanobiotechnology Laboratory, and the Basque Foundation for Science.

SeeThruEquity sees through Lomiko Metals

The headline is a play on words. Lomiko Metals is in the graphene business (it owns graphite mines which can be turned into graphene and has part ownership of a number graphene-related businesses) and the material, graphene, could lead the way to transparent electronics. When you add an equity firm known as SeeThruEquity issuing a news release about Lomiko, well, the headline wrote itself.

A Dec. 14, 2015 SeeThruEquity news release on Yahoo Finance shares (pun!) the latest doings at Lomiko along with a stock price recommendation (Note: Links have been removed),

SeeThruEquity, a leading New York City based independent equity research and corporate access firm focused on smallcap and microcap public companies, today announced that it has issued an update note on Lomiko Metals, Inc. (TSXV: LMR.V, OTCQX: LMRMF).

The note is available here: LMR December 2015 Update. SeeThruEquity is an approved equity research contributor on Thomson First Call, Capital IQ, FactSet, and Zack’s. The report will be available on these platforms. The firm also contributes its estimates to Thomson Estimates, the leading estimates platform on Wall Street.

Based in Vancouver, BC, Lomiko Metals, Inc. (TSXV: LMR.V. OTCQX: LMRMF, “Lomiko”) is an exploration-stage company engaged in the acquisition, exploration and development of resource properties that contain minerals for the new green economy, specifically graphite. In addition to developing high quality graphite plays, including the La Loutre Crystalline Flake Graphite Property and the Quatre Milles Graphite Properties in Quebec, Lomiko is pursuing synergistic growth opportunities in the technology and new energy markets, which leverage its position in the manufacturing graphene, a graphite derivative up to 200x stronger than structural steel that also possesses very high thermal and electrical conductivity properties. These opportunities include the 3D printing, lithium ion battery, LED drivers and power conversion products.

Promising results from infill drilling at La Loutre

As part of a drilling campaign leading to a 43-101 resource estimate, Lomiko intersected 21.55 meters of 11.58%, 57.95 meters of 3.36% including 6.10 meters of 13.66% and 28.75 meters at 4.44% flake graphite at the La Loutre. On December 4, 2015, Lomiko announced that they had intersected 37.40 meters of 4.41% including 10.25 meters of 5.62%, and 48.05 meters of 3.12% including 8.90 meters of 6.13% flake graphite at their 2,867.29 hectare La Loutre Crystalline Flake Graphite Property. A Drill Map is available on the Lomiko web site under quicklinks.

Lomiko management indicated that the results showed “excellent” data including near-surface, high grade flake graphite, helping further define the play’s potential. Lomiko acquired a 40% interest in this promising crystalline flake graphite play in September 2014, and has acquired another 40% interest since we initiated coverage on the company. As we indicated in our initiation of Lomiko, there are several long-term demand catalysts for high grade graphite, including from the lithium ion battery industry, automotive demand from projects similar to the Tesla Gigafactory — which promises to have 35GWh/year of production, as well as potential new applications of graphite derivative graphene, among others.

Launch of Spider Charger(TM) moving towards collaboration

Lomiko’s wholly owned subsidiary, Lomiko Technologies, appears to be nearing commercialization for its innovative new Spider Charger, which has been developed by the company as a result of technology acquired through Lomiko’s December 2014 licensing agreement with Megahertz Power Systems Ltd. The Spider Charger(TM) is an in-wall USB charging device that employs a sleek design while improving energy efficiency for customers and allowing up to eight electronic devices (two standard, 6 via USB ports) to charge safely at one time. Lomiko completed a prototype for the Spider Charger(TM) in November and has manufactured 250 units for use for demonstration with new potential commercial customers. There is clearly a large market potential for the Spider Charger(TM), which has applications for residential and commercial builders, airlines, schools, and businesses with clientele seeking charging stations for their portable electronic devices – such as coffee houses. Lomiko recently initiated a Kickstarter campaign to fund safety and green certifications for commercial use.

Maintain price target of C$0.19

We are maintaining our price target of C$0.19 for Lomiko Metals at this time. We see the company as an intriguing, speculative investment in the graphite and graphene markets.

Please note, I’m not endorsing either the analysis or Lomiko Metals. That said, Lomiko Metals has made some interesting moves in attempts to develop applications for graphene. It’s all very well to have deposits of graphite flakes that can be turned into graphene but if there’s no market for graphene (applications for it) then who cares about the deposits? So, good on Lomiko for its development efforts.

One final comment, for those who do not know, graphene is the focus of much international interest in a race to find applications that utilize it. For example, the European Union has a 1B Euro research fund (the Graphene Flagship) being disbursed over a 10 year period.

Scaling graphene production up to industrial strength

If graphene is going to be a ubiquitous material in the future, production methods need to change. An Aug. 7, 2015 news item on Nanowerk announces a new technique to achieve that goal,

Producing graphene in bulk is critical when it comes to the industrial exploitation of this exceptional two-dimensional material. To that end, [European Commission] Graphene Flagship researchers have developed a novel variant on the chemical vapour deposition process which yields high quality material in a scalable manner. This advance should significantly narrow the performance gap between synthetic and natural graphene.

An Aug. 7, 2015 European Commission Graphene Flagship press release by Francis Sedgemore, which originated the news item, describes the problem,

Media-friendly Nobel laureates peeling layers of graphene from bulk graphite with sticky tape may capture the public imagination, but as a manufacturing process the technique is somewhat lacking. Mechanical exfoliation may give us pristine graphene, but industry requires scalable and cost-effective production processes with much higher yields.

On to the new method (from the press release),

Flagship-affiliated physicists from RWTH Aachen University and Forschungszentrum Jülich have together with colleagues in Japan devised a method for peeling graphene flakes from a CVD substrate with the help of intermolecular forces. …

Key to the process is the strong van der Waals interaction that exists between graphene and hexagonal boron nitride, another 2d material within which it is encapsulated. The van der Waals force is the attractive sum of short-range electric dipole interactions between uncharged molecules.

Thanks to strong van der Waals interactions between graphene and boron nitride, CVD graphene can be separated from the copper and transferred to an arbitrary substrate. The process allows for re-use of the catalyst copper foil in further growth cycles, and minimises contamination of the graphene due to processing.

Raman spectroscopy and transport measurements on the graphene/boron nitride heterostructures reveals high electron mobilities comparable with those observed in similar assemblies based on exfoliated graphene. Furthermore – and this comes as something of a surprise to the researchers – no noticeable performance changes are detected between devices developed in the first and subsequent growth cycles. This confirms the copper as a recyclable resource in the graphene fabrication process.

“Chemical vapour deposition is a highly scalable and cost-efficient technology,” says Christoph Stampfer, head of the 2nd Institute of Physics A in Aachen, and co-author of the technical article. “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. We demonstrate a novel fabrication process based on CVD that yields ultra-high quality synthetic graphene samples. The process is in principle suitable for industrial-scale production, and narrows the gap between graphene research and its technological applications.”

With their dry-transfer process, Banszerus and his colleagues have shown that the electronic properties of CVD-grown graphene can in principle match those of ultrahigh-mobility exfoliated graphene. The key is to transfer CVD graphene from its growth substrate in such a way that chemical contamination is avoided. The high mobility of pristine graphene is thus preserved, and the approach allows for the substrate material to be recycled without degradation.

Musical suite at Graphene Week 2015

Graphene Week 2015 was held in Manchester, UK from June 22 – 26, 2015. (Some might call Manchester the home of graphene as it was first isolated at the University of Manchester by Andre Geim and Konstantin [Kostya] Novoselov  in 2004). As part of the Graphene week festivities and activities, a musical composition, Graphene Suite was premiered according to a July 3, 2015 news item on Azonano,

At Graphene Week 2015 in Manchester, delegates and others were treated to the premiere of a musical suite by Sara Lowes, composer-in-residence at the National Graphene Institute. Sara’s Graphene Suite was commissioned by Brighter Sound, a Manchester-based producer of creative music projects and other cultural events.

A June 26, 2015 Graphene Flagship press release by Frances Sedgemore, which originated the news item, reveals more about the music,

Graphene Suite is scored for a somewhat unusual combination of musical forces, with a string quartet joined by oboe, trumpet, percussion, electric bass guitar, electric guitar and electronic keyboards. Strong visual effects accompanied the musical performance, with electronically manipulated video images of the musicians projected onto a screen behind the stage. For the Graphene Week participants present, the music was a welcome cultural complement to an intense programme of science-centred events.

The Graphene Suite has six movements, and the number six features strongly in the structure of the piece. Here it is sufficient to say that the performance was for this scientist-writer and sometime musician utterly fascinating. In technical terms the music is electro-acoustic, but at the same time Sara’s compositional style is traditional. It is also strongly melodic.

Immediately following the concert I conducted a video interview with the composer, focussing on her music, her experience of the graphene science community, and the nature of and similarities between art and science as creative processes.

The interview which includes some of the music is courtesy of the Graphene Flagship ,

According to the Bright Lights undated [2015] news release, there were two full performances on June 25 and June 26, 2015 while excerpts were performed at Manchester’s Museum of Science and Industry on June 27 and June 28, 2015.

SEMANTICS, a major graphene project based in Ireland

A Jan. 28, 2015 news item on Nanowerk profiles SEMANTICS, a major graphene project based in Ireland (Note: A link has been removed),

Graphene is the strongest, most impermeable and conductive material known to man. Graphene sheets are just one atom thick, but 200 times stronger than steel. The European Union is investing heavily in the exploitation of graphene’s unique properties through a number of research initiatives such as the SEMANTICS project running at Trinity College Dublin.

A Dec. 16, 2014 European Commission press release, which originated the news item, provides an overview of the graphene enterprise in Europe,

It is no surprise that graphene, a substance with better electrical and thermal conductivity, mechanical strength and optical purity than any other, is being heralded as the ‘wonder material’ of the 21stcentury, as plastics were in the 20thcentury.

Graphene could be used to create ultra-fast electronic transistors, foldable computer displays and light-emitting diodes. It could increase and improve the efficiency of batteries and solar cells, help strengthen aircraft wings and even revolutionise tissue engineering and drug delivery in the health sector.

It is this huge potential which has convinced the European Commission to commit €1 billion to the Future and Emerging Technologies (FET) Graphene Flagship project, the largest-ever research initiative funded in the history of the EU. It has a guaranteed €54 million in funding for the first two years with much more expected over the next decade.

Sustained funding for the full duration of the Graphene Flagship project comes from the EU’s Research Framework Programmes, principally from Horizon 2020 (2014-2020).

The aim of the Graphene Flagship project, likened in scale to NASA’s mission to put a man on the moon in the 1960s, or the Human Genome project in the 1990s, is to take graphene and related two-dimensional materials such as silicene (a single layer of silicon atoms) from a state of raw potential to a point where they can revolutionise multiple industries and create economic growth and new jobs in Europe.

The research effort will cover the entire value chain, from materials production to components and system integration. It will help to develop the strong position Europe already has in the field and provide an opportunity for European initiatives to lead in global efforts to fully exploit graphene’s miraculous properties.

Under the EU plan, 126 academics and industry groups from 17 countries will work on 15 individual but connected projects.

The press release then goes on to describe a new project, SEMANTICS,

… this is not the only support being provided by the EU for research into the phenomenal potential of graphene. The SEMANTICS research project, led by Professor Jonathan Coleman at Trinity College Dublin, is funded by the European Research Council (ERC) and has already achieved some promising results.

The ERC does not assign funding to particular challenges or objectives, but selects the best scientists with the best ideas on the sole criterion of excellence. By providing complementary types of funding, both to individual scientists to work on their own ideas, and to large-scale consortia to coordinate top-down programmes, the EU is helping to progress towards a better knowledge and exploitation of graphene.

“It is no overestimation to state that graphene is one of the most exciting materials of our lifetime,” Prof. Coleman says. “It has the potential to provide answers to the questions that have so far eluded us. Technology, energy and aviation companies worldwide are racing to discover the full potential of graphene. Our research will be an important element in helping to realise that potential.”

With the help of European Research Council (ERC) Starting and Proof of Concept Grants, Prof. Coleman and his team are researching methods for obtaining single-atom layers of graphene and other layered compounds through exfoliation (peeling off) from the multilayers, followed by deposition on a range of surfaces to prepare films displaying specific behaviour.

“We’re working towards making graphene and other single-atom layers available on an economically viable industrial scale, and making it cheaply,” Prof. Coleman continues.

“At CRANN [Centre for Research on Adaptive Nanostructures and Nanodevices at Trinity College Dublin], we are developing nanosheets of graphene and other single-atom materials which can be made in very large quantities,” he adds. “When you put these sheets in plastic, for example, you make the plastic stronger. Not only that – you can massively increase its electrical properties, you can improve its thermal properties and you can make it less permeable to gases. The applications for industry could be endless.”

Prof. Coleman admits that scientists are regularly taken aback by the potential of graphene. “We are continually amazed at what graphene and other single-atom layers can do,” he reveals. “Recently it has been discovered that, when added to glue, graphene can make it more adhesive. Who would have thought that? It’s becoming clear that graphene just makes things a whole lot better,” he concludes.

So far, the project has developed a practical method for producing two-dimensional nanosheets in large quantities. Crucially, these nanosheets are already being used for a range of applications, including the production of reinforced plastics and metals, building super-capacitors and batteries which store energy, making cheap light detectors, and enabling ultra-sensitive position and motion sensors. As the number of application grows, increased demand for these materials is anticipated. In response, the SEMANTICS team has scaled up the production process and is now producing 2D nanosheets at a rate more than 1000 times faster than was possible just a year ago.

I believe that new graphene production process is the ‘blender’ technique featured here in an April 23, 2014 post. There’s also a profile of the ‘blender’ project  in a Dec. 10, 2014 article by Ben Deighton for the European Commission’s Horizon magazine (Horizon 2020 is the European Union’s framework science funding programme). Deighton’s article hosts a video of Jonathan Coleman speaking about nanotechnology, blenders, and more on Dec. 1, 2014 at TEDxBrussels.

Chalmers University gears up to offer Graphene Science and Technology, an online, international course

They’ll be offering a MOOC, massive open online course, at Chalmers University of Technology, Sweden, on the topic of graphene starting March 23, 2015 according a Nov. 21, 2014 news item on Nanowerk,

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.

A Nov. 21, 2014 Chalmers University press release on mydesk.com, which seems to have originated the news item, notes that the university is the consortium lead on the European Union’s Graphene Flagship project,

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.

They do have a course prerequisite, from the Introduction to Graphene Science and Technology course,

In order to benefit fully from this course you should have an adequate knowledge of general physics and university level mathematics.

Here’s a video of Jie Sun talking about graphene and his course,

Enjoy the course!
