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!

Graphene and an artificial retina

A graphene-based artificial retina project has managed to intermingle the European Union’s two major FET (Future and Emerging Technologies) funding projects, 1B Euros each to be disbursed over 10 years, the Graphene Flagship and the Human Brain Project. From an Aug. 7, 2014 Technische Universitaet Muenchen (TUM) news release (also on EurekAlert),

Because of its unusual properties, graphene holds great potential for applications, especially in the field of medical technology. A team of researchers led by Dr. Jose A. Garrido at the Walter Schottky Institut of the TUM is taking advantage of these properties. In collaboration with partners from the Institut de la Vision of the Université Pierre et Marie Curie in Paris and the French company Pixium Vision, the physicists are developing key components of an artificial retina made of graphene.

Retina implants can serve as optical prostheses for blind people whose optical nerves are still intact. The implants convert incident light into electrical impulses that are transmitted to the brain via the optical nerve. There, the information is transformed into images. Although various approaches for implants exist today, the devices are often rejected by the body and the signals transmitted to the brain are generally not optimal.

Already funded by the Human Brain Project as part of the Neurobotics effort, Garrido and his colleagues will now also receive funding from the Graphene Flagship. As of July 2014, the Graphene Flagship has added 86 new partners including TUM according to the news release.

Here’s an image of an ‘invisible’ graphene sensor (a precursor to developing an artificial retina),

Artificial retinas were first featured on this blog in an Aug. 18, 2011 posting about video game Deus Ex: Human Revolution which features a human character with artificial sight. The post includes links to a video of a scientist describing an artificial retina trial with 30 people and an Israeli start-up company, ‘Nano Retina’, along with information about ‘Eyeborg’, a Canadian filmmaker who on losing an eye in an accident had a camera implanted in the previously occupied eye socket.

More recently, a Feb. 15, 2013 posting featured news about the US Food and Drug Administration’s decision to allow sale of the first commercial artificial retinas in the US in the context of news about a neuroprosthetic implant in a rat which allowed it to see in the infrared range, normally an impossible feat.

Graphene Flagship experiences an upsurge in new partners

Almost doubling in size, from 78 partners to 140 partners, the European Union’s Graphene Flagship is doing nicely. From a June 23, 2014 news item on Nanowerk (Note: A link has been removed),

To coincide with Graphene Week 2014, the Graphene Flagship announced that today one of the largest-ever European research initiatives is doubling in size. 66 new partners are being invited to join the consortium following the results of a €9 million competitive call. [emphasis mine]

While most partners are universities and research institutes, the share of companies, mainly SMEs [small to medium enterprises], involved is increasing. This shows the growing interest of economic actors in graphene. The partnership now includes more than 140 organisations from 23 countries. [emphasis mine] It is fully set to take ‘wonder material’ graphene and related layered materials from academic laboratories to everyday use.

A June 23, 2014 Graphene Flagship news release (also on EurekAlert), which originated the news item, provides more detail about the partners and the call which attracted them,

The 66 new partners come from 19 countries, six of which are new to the consortium: Belarus, Bulgaria, the Czech Republic, Estonia, Hungary and Israel.

With its 16 new partners, Italy now has the highest number of partners in the Graphene Flagship alongside Germany (with 23 each), followed by Spain (18), UK (17) and France (13).

The incoming 66 partners will add new capabilities to the scientific and technological scope of the flagship. Over one third of new partners are companies, mainly SMEs, showing the growing interest of economic actors in graphene. In the initial consortium this ratio was 20%.

Big Interest in Joining the Initiative

The €9 million competitive call of the €54 million ramp-up phase (2014-2015) attracted a total of 218 proposals, representing 738 organisations from 37 countries. The proposals received were evaluated on the basis of their scientific and technological expertise, implementation and impact (further information on the call) and ranked by an international panel of leading experts, mostly eminent professors from all over the world. 21 proposals were selected for funding.

Prof. Jari Kinaret, Professor of Physics at the Chalmers University of Technology, Sweden, and Director of the Graphene Flagship, said: “The response was overwhelming, which is an indicator of the recognition for and trust in the flagship effort throughout Europe. Competition has been extremely tough. I am grateful for the engagement by the applicants and our nearly 60 independent expert reviewers who helped us through this process. I am impressed by the high quality of the proposals we received and looking forward to working with all the new partners to realise the goals of the Graphene Flagship.”

Europe in the Driving Seat

Graphene was made and tested in Europe, leading to the 2010 Nobel Prize in Physics for Andre Geim and Konstantin Novoselov from the University of Manchester.

With the €1 billion Graphene Flagship, Europe will be able to turn cutting-edge scientific research into marketable products. This major initiative places Europe in the driving seat for the global race to develop graphene technologies.

Prof. Andrea Ferrari, Director of the Cambridge Graphene Centre and Chair of the Executive Board of the Graphene Flagship commented today’s announcement on new partners: “This adds strength to our unprecedented effort to take graphene and related materials from the lab to the factory floor, so that the world-leading position of Europe in graphene science can be translated into technology, creating a new graphene-based industry, with benefits for Europe in terms of job creation and competitiveness”.

For anyone unfamiliar with the Graphene Flagship, the news release provides this backgrounder,

The Graphene Flagship @GrapheneCA represents a European investment of €1 billion over the next 10 years. It is part of the Future and Emerging Technologies (FET) Flagships @FETFlagships announced by the European Commission in January 2013 (press release). The goal of the FET Flagships programme is to encourage visionary research with the potential to deliver breakthroughs and major benefits for European society and industry. FET Flagships are highly ambitious initiatives involving close collaboration with national and regional funding agencies, industry and partners from outside the European Union.

Research in the next generation of technologies is key for Europe’s competitiveness. This is why €2.7 billion will be invested in Future and Emerging Technologies (FET) under the new research programme Horizon 2020 #H2020 (2014-2020). This represents a nearly threefold increase in budget compared to the previous research programme, FP7. FET actions are part of the Excellent science pillar of Horizon 2020.

You can find a full press kit for this announcement here, it includes,

I have long wondered how Sweden became the lead for the European Union effort. It seemed odd given that much of the initial work was done at the University of Manchester and the UK has not been shy about its ambition to lead the graphene effort internationally.

Flatland, an 1884 novella or optics with graphene?

Flatland is both novella and a story about optics with graphene. First, here’s more about the novella from its Wikipedia entry (Note: Links have been removed),

Flatland: A Romance of Many Dimensions is an 1884 satirical novella by the English schoolmaster Edwin Abbott Abbott. Writing pseudonymously as “A Square”,[1] the book used the fictional two-dimensional world of Flatland to offer pointed observations on the social hierarchy of Victorian culture. However, the novella’s more enduring contribution is its examination of dimensions.[2]

For the uninitiated, graphene is two-dimensional and, apparently, this characteristic could prove helpful for new types of optics (from a May 23, 2014 news item on Nanowerk; Note:  Links have been removed),

Researchers from CIC nanoGUNE, in collaboration with ICFO  [Institute of Photonic Sciences] and Graphenea, introduce a platform technology based on optical antennas for trapping and controlling light with the one-atom-thick material graphene. The experiments show that the dramatically squeezed graphene-guided light can be focused and bent, following the fundamental principles of conventional optics. The work, published yesterday in Science (“Controlling graphene plasmons with resonant metal antennas and spatial conductivity patterns”), opens new opportunities for smaller and faster photonic devices and circuits.

A May 23, 2014 CIC nanoGUNE news release (also on EurekAlert), which originated the news item,

Optical circuits and devices could make signal processing and computing much faster. “However, although light is very fast it needs too much space”, explains Rainer Hillenbrand, Ikerbasque Professor at nanoGUNE and UPV/EHU. In fact, propagating light needs at least the space of half its wavelength, which is much larger than state-of-the-art electronic building blocks in our computers. For that reason, a quest for squeezing light to propagate it through nanoscale materials arises.

The wonder material graphene, a single layer of carbon atoms with extraordinary properties, has been proposed as one solution. The wavelength of light captured by a graphene layer can be strongly shortened by a factor of 10 to 100 compared to light propagating in free space. As a consequence, this light propagating along the graphene layer – called graphene plasmon – requires much less space.

However, transforming light efficiently into graphene plasmons and manipulating them with a compact device has been a major challenge. A team of researchers from nanoGUNE, ICFO and Graphenea – members of the EU Graphene Flagship – now demonstrates that the antenna concept of radio wave technology could be a promising solution. The team shows that a nanoscale metal rod on graphene (acting as an antenna for light) can capture infrared light and transform it into graphene plasmons, analogous to a radio antenna converting radio waves into electromagnetic waves in a metal cable.

“We introduce a versatile platform technology based on resonant optical antennas for launching and controlling of propagating graphene plasmons, which represents an essential step for the development of graphene plasmonic circuits”, says team leader Rainer Hillenbrand. Pablo Alonso-González, who performed the experiments at nanoGUNE, highlights some of the advantages offered by the antenna device: “the excitation of graphene plasmons is purely optical, the device is compact and the phase and wavefronts of the graphene plasmons can be directly controlled by geometrically tailoring the antennas. This is essential to develop applications based on focusing and guiding of light”.

The news release describes few of the more technical aspects of the research,

The research team also performed theoretical studies. Alexey Nikitin, Ikerbasque Research Fellow at nanoGUNE, performed the calculations and explains that “according to theory, the operation of our device is very efficient, and all the future technological applications will essentially depend upon fabrication limitations and quality of graphene”.

Based on Nikitin´s calculations, nanoGUNE’s Nanodevices group fabricated gold nanoantennas on graphene provided by Graphenea. The Nanooptics group then used the Neaspec near-field microscope to image how infrared graphene plasmons are launched and propagate along the graphene layer. In the images, the researchers saw that, indeed, waves on graphene propagate away from the antenna, like waves on a water surface when a stone is thrown in.

In order to test whether the two-dimensional propagation of light waves along a one-atom-thick carbon layer follow the laws of conventional optics, the researchers tried to focus and refract the waves. For the focusing experiment, they curved the antenna. The images then showed that the graphene plasmons focus away from the antenna, similar to the light beam that is concentrated with a lens or concave mirror.

The team also observed that graphene plasmons refract (bend) when they pass through a prism-shaped graphene bilayer, analogous to the bending of a light beam passing through a glass prism. “The big difference is that the graphene prism is only two atoms thick. It is the thinnest refracting optical prism ever”, says Rainer Hillenbrand. Intriguingly, the graphene plasmons are bent because the conductivity in the two-atom-thick prism is larger than in the surrounding one-atom-thick layer. In the future, such conductivity changes in graphene could be also generated by simple electronic means, allowing for highly efficient electric control of refraction, among others for steering applications.

Altogether, the experiments show that the fundamental and most important principles of conventional optics also apply for graphene plasmons, in other words, squeezed light propagating along a one-atom-thick layer of carbon atoms. Future developments based on these results could lead to extremely miniaturized optical circuits and devices that could be useful for sensing and computing, among other applications.

Graphene hype; the emerging story in an interview with Carla Alvial Palavicino (University of Twente, Netherlands)

i’m delighted to be publishing this interview with Carla Alvial Palavicino, PhD student at the University of Twente (Netherlands), as she is working on the topicof  graphene ‘hype’. Here’s a bit more about the work from her University of Twente webpage (Note: A link has been removed),

From its origins the field of nanotechnology has been populated of expectations. Pictured as “the new industrial revolution” the economic promise holds strong, but also nanotechnologies as a cure for almost all the human ills, sustainers of future growth, prosperity and happiness. In contrast to these promises, the uncertainties associated to the introduction of such a new and revolutionary technology, and mainly risks of nanomaterials, have elicited concerns among governments and the public. Nevertheless, the case of the public can be characterized as concerns about concerns, based on the experience of previous innovations (GMO, etc.).

Expectations, both as promises and concerns, have played and continue playing a central role in the “real-time social and political constitution of nanotechnology” (Kearnes and Macnaghten 2006). A circulation of visions, promises and concerns in observed in the field, from the broadly defined umbrella promises to more specific expectations, and references to grand challenges as moral imperatives. These expectations have become such an important part of the social repertoire of nano applications that we observe the proliferation of systematic and intentional modes of expectation building such as roadmaps, technology assessment, etc.; as well as a considerable group of reports on risk, concerns, and ethical and social aspects. This different modes of expectation building (Konrad 2010) co-exist and contribute to the articulation of the nano field.

This project seeks to identify, characterize and contextualize the existing modes of expectations building, being those intentional (i.e. foresight, TA, etc.) or implicit in arenas of public discourse, associated to ongoing and emerging social processes in the context of socio-technical change.

This dynamics are being explored in relation to the new material graphene.

Before getting to the interview, here’s Alvial Palavicino’s biography,

Carla Alvial Palavicino has a bachelor degree in Molecular Biology Engineering, School of Science, University of Chile, Chile and a Master’s degree on Sustainability Sciences, Graduate School of Frontier Science, University of Tokyo, Japan. She has worked in technology transfer and more recently, in Smart Grids and local scale renewable energy provision.

Finally, here’s the interview (Note: At the author’s request, there have been some grammatical changes made to conform with Canadian English.),

  • What is it that interests you about the ‘hype’ that some technologies receive and how did you come to focus on graphene in particular?

My research belongs to a field called the Sociology of Expectations, which deals with the role of promises, visions, concerns and ideas of the future in the development of technologies, and how these ideas actually affect people’s strategies in technology development. Part of the dynamic found for these expectations are hype-disappointment cycles, much like the ones the Gartner Group uses. And hype has become an expectation itself; people expect that there will be too many promises and some, maybe many of them are not going to be fulfilled, followed by disappointment.

I came to know about graphene because, initially, I was broadly interested in nanoelectronics (my research project is part of NanoNextNL a large Dutch Nano research programme), due to the strong future orientation in the electronics industry. The industry has been organizing, and continues to organize around the promise of Moore’s law for more than 50 years! So I came across graphene as thriving to some extent on the expectations around the end of Moore’s law and because simply everybody was talking about it as the next big thing! Then I thought, this is a great opportunity to investigate hype in real-time

  • Is there something different about the hype for graphene or is this the standard ‘we’ve found a new material and it will change everything’?

I guess with every new technology and new material you find a portion of genuine enthusiasm which might lead to big promises. But that doesn’t necessarily turn into big hype. One thing is that all hype is not the same and you might have technologies that disappeared after the hype such as High Temperature Semiconductors, or technologies that go through a number of hype cycles and disappointment cycles throughout their development (for example, Fuel Cells). Now with graphene what you certainly have is very ‘loud’ hype – the amount of attention it has received in so little time is extraordinary. If that is a characteristic of graphene or a consequence of the current conditions in which the hype has been developed, such as faster ways of communication (social media for example) or different incentives for science and innovation well, this is part of what I am trying to find out.

Quite clearly, the hype in graphene seems to be more ‘reflexive’ than others, that is, people seem to be more conscious about hype now. We have had the experience with carbon nanotubes only recently and scientist, companies and investors are less naïve about what can be expected of the technology, and what needs to be done to move it forward ‘in the right direction’. And they do act in ways that try to soften the slope of the hype-disappointment curve. Having said that, actors [Ed. Note: as in actor-network theory] are also aware of how they can take some advantage of the hype (for funding, investment, or another interest), how to make use of it and hopefully leave safely, before disappointment. In the end, it is rather hard to ask accountability of big promises over the long-term.

  • In the description of your work you mention intentional and implicit modes of building expectations, could explain the difference between the two?

One striking feature of technology development today is that we found more and more activities directed at learning about, assess, and shaping the future, such as forecasts, foresights, Delphi, roadmaps and so on. There are even specialized future actors such as consultancy organisations or foresight experts,  Cientifica among them. And these formalized ways of anticipating  the future are expected to be performative by those who produce them and use them, that is, influence the way the future – and the present- turns out. But this is not a linear story, it’s not like 100% of a roadmap can be turned practice (not even for the ITRS roadmap [Ed. Note: International Technology Roadmap for Semi-conductors] that sustains Moore’s law, some expectations change quite radically between editions of the roadmap). Besides that, there are other forms of building expectations which are embedded in practices around new technologies. Think of the promises made in high profile journals or grant applications; and of expectations incorporated in patents and standards. All these embody particular forms and directions for the future, and exclude others. These are implicit forms of expectation-building, even if not primarily intended as such. These forms are shaped by particular expectations which themselves shape further development. So, in order to understand how these practices, both intentional and implicit, anticipate futures you need to look at the interplay between the various types.

  • Do you see a difference internationally with regard to graphene hype? Is it more prevalent in Europe than in the North America? Is it particularly prevalent in some jurisdiction, e.g. UK?

I think the graphene ‘hype’ has been quite global, but it is moving to different communities, or actors groups, as Tim Harper from Cientifica has mentioned in his recent report about graphene

What is interesting in relation to the different ‘geographical’ responses to graphene is that they exemplify nicely how a big promise (graphene, in this case) is connected to other circulating visions, expectations or concerns. In the case of the UK, the *Nobel prize on Graphene and the following investment was connected to the idea of a perceived crisis of innovation in the country. Thus, the decision to invest in graphene was presented and discussed in reference to global competitiveness, showing a political commitment for science and innovation that was in doubt at that time.

In the European case with its *Graphene flagship, something similar happened. While there is no doubt of the scientific excellence of the flagship project, the reasons why it finally became a winner in the flagship competition might have been related to the attention on graphene. The project itself started quite humbly, and it differed from the other flagship proposals that were much more oriented towards economic or societal challenges. But the attention graphene received after the Nobel Prize, plus the engagement of some large companies, helped to frame the project in terms of its economic profitability.  And. this might have helped to bring attention and make sense of the project in the terms the European Commission was interested in.

In contrast, if you think of the US, the hype has been there (the number of companies engaged in graphene research is only increasing) but it has not had a big echo in policy. One of the reasons might be because this idea of global competition and being left behind is not so present in the US. And in the case of Canada for example, graphene has been taken up by the graphite (mining) community, which is a very local feature.

So answering your questions, the hype has been quite global and fed in a global way (developments in one place resonate in the other) but different geographical areas have reacted in relation to their contingent expectations to what this hype dynamic provided.

  • What do you think of graphene?

I think it’s the new material with more YouTube videos (this one is particularly good in over promising for example)  and the coolest superhero (Mr G from the Flagship). But seriously,  I often get asked that question when I do interviews with actors in the field, since they are curious to learn about the outsider perspective. But to be honest I try to remain as neutral and distant as possible regarding my research object… and not getting caught in the hype!

Thanks so much for a fascinating interview Carla and I very much appreciate the inclusion of Canada in your response to the question about the international response to graphene hype. (Here are three of my postings on graphite and mining in Canada: Canada’s contribution to graphene research: big graphite flakes [Feb. 6, 2012]; A ‘graphite today, graphene tomorrow’ philosophy from Focus Graphite [April 17, 2013[; and Lomiko’s Quatre Milles graphite flakes—pure and ultra pure [April 17, 2013] There are others you can find by searching ‘graphite’ in the blog’s search box.)

* For anyone curious about the Nobel prize and graphene, there’s this Oct.7, 2010 posting. Plus, the Graphene Flagship was one of several projects competing for one of the two 1B Euro research prizes awarded in January 2013 (the win is mentioned in my Jan. 28, 2013 posting).

Merry Christmas, Happy New Year, and Happy Holidays to all!
