Three teams observe graphene butterflies

Thursday, May 16th, 2013

It took me a few minutes to find the butterflies (visual pattern recognition is not one of my strengths) but here they are,

The May 15, 2013 University of Manchester news release (on EurekAlert and on the University of Manchester news site) describes how the ‘butterflies’ are formed,

Writing in Nature, a large international team led Dr Roman Gorbachev from The University of Manchester shows that, when graphene placed on top of insulating boron nitride, or ‘white graphene’, the electronic properties of graphene change dramatically revealing a pattern resembling a butterfly.

The pattern is referred to as the elusive Hofstadter butterfly that has been known in theory for many decades but never before observed in experiments.

More of the science needs to be explained before moving on with the ‘butterflies’ (from the news release),

One of the most remarkable properties of graphene is its high conductivity – thousands of times higher than copper. This is due to a very special pattern created by electrons that carry electricity in graphene. The carriers are called Dirac fermions and mimic massless relativistic particles called neutrinos, studies of which usually require huge facilities such as at CERN. The possibility to address similar physics in a desk-top experiment is one of the most renowned features of graphene.

Now the Manchester scientists have found a way to create multiple clones of Dirac fermions. Graphene is placed on top of boron nitride so that graphene’s electrons can ‘feel’ individual boron and nitrogen atoms. Moving along this atomic ‘washboard’, electrons rearrange themselves once again producing multiple copies of the original Dirac fermions.

Here’s where the butterflies appear (from the news release),

The researchers can create even more clones by applying a magnetic field. The clones produce an intricate pattern; the Hofstadter butterfly. It was first predicted by mathematician Douglas Hofstadter in 1976 and, despite many dedicated experimental efforts, no more than a blurred glimpse was reported before.

In addition to the described fundamental interest, the Manchester study proves that it is possible to modify properties of atomically-thin materials by placing them on top of each other. This can be useful, for example, for graphene applications such as ultra-fast photodetectors and transistors, providing a way to tweak its incredible properties.

Coincidentally, another team has also observed the Hofstadter butterfly on a graphene substrate. From the May 16, 2013 news item on Azonano,

Two research teams at the National High Magnetic Field Laboratory (MagLab) broke through a nearly 40-year barrier recently when they observed a never-before-seen energy pattern.

“The observation of the ‘Hofstadter butterfly’ marks a real landmark in condensed matter physics and high magnetic field research,” said Greg Boebinger, director of the MagLab. “It opens a new experimental direction in materials research.”

This groundbreaking research demanded the ability to measure samples of materials at very low temperatures and very high magnetic fields, up to 35 tesla. Both of those conditions are available at the MagLab, making it an international destination for scientific exploration.

The unique periodic structure used to observe the butterfly pattern was composed of boron nitride (BN) and graphene.

The May 15, 2013 Florida State University news release by Kristin Roberts, which originated the news item, describes the two teams using the MagLab facilities for their ‘butterfly’ observations,

One research team was led by Columbia University’s Philip Kim and included researchers from City University of New York, the University of Central Florida, Tohoku University and the National Institute for Materials Science in Japan. The team’s work will be published today in the Advanced Online Publication of the journal Nature. Similar results were discovered at the MagLab by a group led by Pablo Jarillo-Herrero and Raymond Ashoori at MIT, as well as scientists from Tohoku University and the National Institute for Materials Science in Japan. Their work is expected to be published soon.

For those who just can’t get enough graphene butterflies here are citations for and links to both recently published papers (the Jarillo-Herrero/Ashoori team will be publishing their work soon).

£50,000 graphene enterprise competition at the University of Manchester

Thursday, February 28th, 2013

The Feb. 28, 2013 news item on Azonano about the University of  Manchester’s latest graphene initiative notes, rather unusually (these things are usually announced at press conferences), the announcement about a £50,000 graphene award was made at a staff event,

The University of Manchester launched an £50,000 enterprise competition for students with new graphene ideas at a staff event attended by more than 500 people.

The Eli and Britt Harari Graphene Enterprise Award will help establish further enterprises in graphene at the University. The £50,000 award aims to encourage the development of an entrepreneurial culture across the University’s doctoral and postdoctoral research base.

The competition is co-funded by the North American Foundation for The University of Manchester, through the generous support of one of the University’s former students, Dr Eli Harari, and his wife Britt, and the UK Government’s Higher Education Innovation Fund. The award judging panel will be chaired by Andre Geim, Holder of the Langworthy Chair and Regius Professor.

The University of Manchester Feb. 27, 2013 news release, which originated the news item, lists some of the criteria for entering the competition,

The 2013 competition is open to final year PhD students and Postdoctoral Research Associates at the University. It will be awarded to the candidate who can demonstrate outstanding potential in establishing a new enterprise related to graphene and who now wishes to embark on an entrepreneurial career in innovation and commercialisation.

Applications will be judged on the strength of their business plan to develop a new graphene-related business. The award then becomes seed funding to allow the candidate to take the first steps towards realising this plan.  It recognises the role that high-level, flexible early-stage financial support can play in the successful development of a business targeting the full commercialisation of a product or technology related to research in graphene.

Further details of the award can be found at www.graphene.manchester.ac.uk or by emailing Ivan Buckley at ivan.buckley@manchester.ac.uk

I did check the website but was not able to find any additional information so you might want to email Ivan Buckley first.

The race to commercialize graphene as per the University of Manchester (UK)

Tuesday, February 19th, 2013

The University of Manchester (UK) has a particular interest in graphene as the material was isolated by future Nobel Prize winners, Andre Gheim and Kostya (Konstantin) Novoselov in the university’s laboratories. There’s a Feb. 18, 2013 news item on Nanowerk highlighting the university’s past and future role in the development of graphene on the heels of the recent research bonanza,

The European Commission has announced that it is providing 1bn euros over 10 years for research and development into graphene – the ‘wonder material’ isolated at The University of Manchester by Nobel Prize winners Professors Andre Geim and Kostya Novoselov.

The University is very active in technology transfer and has an excellent track-record of spinning out technology, but some think that the University has taken a different view when it comes to patenting and commercialising graphene. Others have expressed a broader concern about British Industry lagging behind in the graphene ‘race’, based upon international ‘league tables’ of numbers of graphene patents.

A recent interview with Clive Rowland (CEO of the University’s Innovation Group) addresses the assumptions about the University’s approach and reflects more generally about graphene patenting and about industry up-take of graphene. The interview is summarised below.

Question: Has the University set up any commercial graphene activities?

Answer: The University owns a company, called 2-DTech Limited, which makes and supplies two-dimensional materials and has an interest in another, Graphene Industries Limited, which sells graphene made by a different technique to 2-DTech.

Question: Is the University falling behind in graphene?

Answer: The University is the world’s leading university for graphene research and publications. It led the charge for UK investment into the field and has been awarded The National Graphene Institute, which will be a £61m state-of-the art centre. This Institute will act as a focus for all sorts of commercial graphene activity in Manchester, from industrial research and development laboratories locating “alongside” the Institute, developing new processes and products, to start-up companies. The University championed the major flagship research funding programmes that have been initiated in the UK and Europe and has been awarded a number of prestigious grants. Graphene is still a science-driven research field and not yet a commercialised technology.

The rest of the summary can be found either at Nanowerk or in this University of Manchester Feb. 18, 2013 news release.

The University of Manchester Innovation Group (aka UMI3) mentioned in connection with Clive Rowland hosts the complete interview (12 pp), which, read from the beginning, provides an enhanced perspective on the university’s graphene commercialization goals,

Graphene – The University of Manchester and Intellectual Property. Dan Cochlin talks to Clive Rowland – The University’s InnovationGroup CEO –‐ about the launch of a new grapheme company at the University, 2–‐DTech Ltd, And grapheme patents and commercialisation.

What is grapheme and why is there so much interest in it?

Graphene is a revolutionary nano material which was first isolated at The University of Manchester By Professors Andre Geim And Konstantin Novoselov. They received the Nobel Prize in 2010 For their ingenious work on graphene. People are excited about it because it has the potential to transform a vast range of products due to its very superior capabilities compared to existing materials.

So what’s the new company about?

It makes and sells CVD graphene, grapheme platelets, grapheme oxide and other advanced materials with amazing properties, which are being called 2–‐D – two dimensional – due to  their single atomic layer thickness. In other words, they’re so thin it’s as if they only have length and breadth dimensions. It will soon have an e–‐commerce site too, where customers can shop on–‐line. The Company will create and develop intellectual property, especially by engaging in interesting assignments such as collaborating with firms on design projects. It will also provide consulting services ,in the field, either directly or by sub–‐contracting to our relevant academic colleagues here at the University. We’re already an international team – with Antiguan, British and Italian people actively involved in the business and a fast developing business agency network in the Far East and the USA.

What’s CVD?

It’s one of the techniques for making grapheme that 2-DTech uses –‐ chemical vapour deposition –‐ which allows us to grow grapheme on foils and films in quite large area sizes for various potential uses, particularly information technology and communications because of graphene’s high quality and unique electronic transport, flexibility and other astounding attributes.

Well why have you only just set this up when others have been doing so for a while now?

The University’s researchers in physics and materials science have been able to make enough grapheme for their own needs until lately, but not any longer. Besides, there has been an expansion of interest across the University in the potential of the material, including from areas such as health and bio–‐sciences. Hence we want to make sure that the University has a regular supply for those colleagues who cannot continue to make it in sufficient quantities or who aren’t familiar with the material.

In addition many of the companies in contact with the University’s Researchers are in a similarly constrained position. So we feel the need to have a University Facility to handle this which is free of the normal academic duties and interests. At the same time we see an international business opportunity.

There’s a strong market demand for high quality grapheme of a consistent nature and a growing interest in other 2–‐D crystals. A number of researchers, especially our CTO Dr Branson Belle, who had been researching 2–‐D Materials and making grapheme for a long time became interested in the business side. …

Thank you Clive Rowland and the University of Manchester for insight into the graphene commercialization efforts on the part of at least one university.  Meanwhile, the comment about producing enough graphene for research reminds me of the queries I get from entrepreneurs about getting access to nanocrystalline cellulose (NCC) or cellulose nanocrystals (CNC). To my knowledge, no one outside the research community has gotten access to the materials. I wonder if despite the fact there are two manufacturing facilities whether this may be due to an inability to produce enough CNC or NCC.

Another day, another graphene centre in the UK as the Graphene flagship consortium’s countdown begins

Thursday, January 24th, 2013

The University of Cambridge has announced a Cambridge Graphene Centre due to open by the end of 2013 according to a Jan. 24, 2012 news item on Nanowerk,

The Cambridge Graphene Centre will start its activities on February 1st 2013, with a dedicated facility due to open at the end of the year. Its objective is to take graphene to the next level, bridging the gap between academia and industry. It will also be a shared research facility with state-of-the-art equipment, which any scientist researching graphene will have the opportunity to use.

The University of Cambridge Jan. 24, 2013 news release, which originated the news item, describes the plans for graphene research and commercialization,

The first job for those working in the Cambridge Graphene Centre will be to find ways of manufacturing and optimising graphene films, dispersions and inks so that it can be used to good effect.

Professor Andrea Ferrari, who will be the Centre’s Director, said: “We are now in the second phase of graphene research, following the award of the Nobel Prize to Geim and Novoselov. That means we are targeting applications and manufacturing processes, and broadening research to other two-dimensional materials and hybrid systems. The integration of these new materials could bring a new dimension to future technologies, creating faster, thinner, stronger, more flexible broadband devices.”

One such project, led by Dr Stephan Hofmann, a Reader and specialist in nanotechnology, will look specifically at the manufacturability of graphene and other, layered, 2D materials. At the moment, sheets of graphene that are just one atom thick are difficult to grow in a controllable manner, manipulate, or connect with other materials.

Dr Hofmann’s research team will focus on a growth method called chemical vapour deposition (CVD), which has already opened up other materials, such as diamond, carbon nanotubes and gallium nitride, to industrial scale production.

“The process technology will open up new horizons for nanomaterials, built layer by layer, which means that it could lead to an amazing range of future devices and applications,” Dr Hofmann said.

The Government funding for the Centre is complemented by strong industrial support, worth an additional £13 million, from over 20 partners, including Nokia, Dyson, Plastic Logic, Philips and BaE systems. A further £11M of European Research Council funding will support activities with the Graphene Institute in Manchester, and Lancaster University. [emphasis mine]

Its work will focus on taking graphene from a state of raw potential to a point where it can revolutionise flexible, wearable and transparent electronics. The Centre will target the manufacture of graphene on an industrial scale, and applications in the areas of flexible electronics, energy, connectivity and optoelectronics.

Professor Yang Hao, of Queen Mary, University of London, will lead Centre activities targeting connectivity, so that graphene can be integrated into networked devices, with the ultimate vision of creating an “internet of things”.

Professor Clare Grey, from Cambridge’s Department of Chemistry, will lead the activities targeting the use of graphene in super-capacitors and batteries for energy storage. The research could, ultimately, provide a more effective energy storage for electric vehicles, storage on the grid, as well as boosting the energy storage possibilities of personal devices such as MP3 players and mobile phones.

The announcement of a National Graphene Institute in Manchester was mentioned in my Jan. 14, 2013 posting and both the University of Manchester and the Lancaster University are part of the Graphene Flagship consortium along with the University of Cambridge and Sweden’s Chalmers University, which is the lead institution, and others competing against three other Flagship projects for one of two 1B Euro prizes.

These two announcements (Cambridge Graphene Centre and National Graphene Institute come at an interesting time, the decision as to which two projects will receive 1B Euros for research is being announced Jan. 28, 2013 in Brussels, Belgium. The Jan. 15, 2013 article by Frank Jordans on the R&D website provides a few more details,

Teams of scientists from across the continent [Europe] are vying for a funding bonanza that could see two of them receive up to €1 billion ($1.33 billion) over 10 years to keep Europe at the cutting edge of technology.

The contest began with 26 proposals that were whittled down to six last year. Just four have made it to the final round.

They include a plan to develop digital guardian angels that would keep people safe from harm; a massive data-crunching machine to simulate social, economic and technological change on our planet; an effort to craft the most accurate computer model of the human brain to date; and a team working to find better ways to produce and employ graphene—an ultra-thin material that could revolutionize manufacturing of everything from airplanes to computer chips.

Jordans’ article goes on to further explain the reasoning for this extraordinary contest. All four groups must be highly focused on Monday’s (Jan. 28, 2013) announcement from EU (European Union) officials, after all, two prizes and four competitors means that the odds of winning are 50/50. Good luck!

National Graphene Institute at the UK’s University of Manchester

Monday, January 14th, 2013

It will house the UK’s graphene research efforts according to the Jan. 14, 2013 news item Nanowerk,

This is the first glimpse of the new £61m research institute into wonder material graphene, which is to be built at The University of Manchester.

The stunning, glass-fronted National Graphene Institute (NGI) will be the UK’s home of research into the world’s thinnest, strongest and most conductive material, providing the opportunity for researchers and industry to work together on a huge variety of potential applications.

The University of Manchester Jan. 14, 2013 news release, which originated the news item, spells out some of the hopes and dreams along with descriptions of the building plans,

It is hoped the centre will initially create around 100 jobs, with the long-term expectation of many thousands more in the North West and more widely in the UK.

The 7,600 square metre building will house state-of-the-art facilities, including two ‘cleanrooms’ – one which will take up the whole of the lower ground floor – where scientists can carry out experiments and research without contamination.

The Institute will also feature a 1,500 square metre research lab for University of Manchester graphene scientists to collaborate with their colleagues from industry and other UK universities.

Funding for the NGI will come from £38m from the Government, as part of £50m allocated for graphene research, and the University has applied for £23m from the European Research and Development Fund (ERDF). The NGI will operate as a ‘hub and spoke’ model, working with other UK institutions involved in graphene research.

Some of the world’s leading companies are also expected to sign up to work at the NGI, where they will be offered the chance to work on cutting edge projects, across various sectors, with Nobel Laureates and other leading members of the graphene team.

Graphene, isolated for the first time at The University of Manchester by Professor Andre Geim and Professor Kostya Novoselov in 2004, has the potential to revolutionise a huge number of diverse applications; from smartphones and ultrafast broadband to drug delivery and computer chips.


Professor Colin Bailey, Vice-President and Dean of the Faculty of Engineering and Physical Sciences, added: “The National Graphene Institute will be the world’s leading centre of graphene research, combining the expertise of University of Manchester academics with their counterparts at other UK universities and with leading global commercial organisations.

“The potential for its impact on the city and the North West is huge, and will be one of the most exciting centres of cutting edge research in the UK.”

Work is set to start on the five-story NGI, which will have its entrance on Booth Street East, in March, and is expected to be completed in early 2015.

FrogHeart at the 2012 S.NET conference, part 2: Canada, nano, and the mango

Thursday, November 1st, 2012

I was delighted to learn more about the nanotechnology collaboration between Canada, India, and Sri Lanka (mentioned in my India, Sri Lanka, and Canada team up for nanotechnology-enabled food packaging posting of June 21, 2012) at the S.Net 2012 conference.

Rumana Bukht and Sally Randles from the University of Manchester’s Business School titled their presentation, Intervention of the State on Responsible Development of Nanotechnology in Canada.

Before discussing the presentation, here’s a summary of the project from my June 21, 2012 posting,

From the June 20, 2012 University of Guelph news release,

University of Guelph scientists led by Prof. Jayasankar Subramanian will work with South Asian colleagues to develop innovative packaging using state-of-the-art nanotechnology to reduce post-harvest losses in mangoes, a vital fruit crop in South Asia.

The $2.3 million project, announced today by Canada’s International Development Research Centre (IDRC) and the Canadian International Development Agency (CIDA), will improve livelihoods for nearly one-third of the populations of India and Sri Lanka, mostly small-scale farmers.

The Guelph scientists will work with researchers from the Tamil Nadu Agricultural University in India and Sri Lanka’s Industrial Technology Institute.

“Invented in part at U of G, this new packaging system should reduce post-harvest losses in fruits in India and Sri Lanka, where optimal storage conditions are not readily available.”

Mangoes are the second largest fruit crop in India and third in Sri Lanka. Farmers lose 35 to 40 per cent of their crops ─ worth $800 million a year ─ because of poor storage.

The researchers will combine patented technologies to develop special fruit cartons, dividers and wraps lined with nanoparticles from coconut husks and banana plants. Using these farm waste products will help provide income for small-scale entrepreneurs, particularly women.

During her talk, Rumana mentioned hexanal as an important ingredient in this new packaging. While my notes don’t provide much information about this ingredient, I did find this great April 26, 2012 article by Arun P Mathew for the Times of India, which provides more technical detail,

K S Subramanian, head of the department of Nano Science and Technology, who is involved in the project said that the University of Guelph, Canada discovered that hexanal, a chemical extracted from plants could successfully enhance the shelf-life and quality of fruits and vegetables. A researcher at TNAU [Tamil Nadu Agricultural University] has come [up] with a nano-film, he said.

“A combination of these two technologies could help develop a nano film with hexanal, which will improve the longevity of these fruits. Through this technology, around 30 percent of the losses could be avoided. This will improve the export of fruits and vegetables and increase the sales of fruits making farming more economically viable,” he said. Subramanian said that they would first be applied on mangoes and later on other fruits, based on its success.

He said that this will be an eco-friendly product. “Hexanal has been approved by United States based, FDA ( Food and Drug Administration). …

Rumana noted there will be safety testing of this hexanal-based nano-film and the testing will take place in India (not Canada) because India has better safety equipment and personnel with the appropriate skill sets. Canada will contribute the safety protocols. If the mango project is successful, researchers are considering plums and peaches for future projects.

I did want to get more  information about this collaboration and about the Canadian nano scene. As I have noted many times, getting information is difficult and I gather Rumana experienced some of the same difficulties. At least, I’m inferring difficulty from the fact that she refused, due to confidentiality agreements, to tell me which Canadian government officials she’d spoken with although she did identify departments (Health Canada and Industry Canada). Given all the secrecy you’d think something nefarious was happening instead of an attempt to minimize food wastage.

Neuronal dance and garage neuroscience experiments

Monday, March 26th, 2012

I found two items about neuroscience in one day that tickled my fancy. The Watching Dance Project funded by the UK Arts and Humanities Research Council recently announced a study that found experienced dance spectators mirrored the movement they were watching. From the March 21, 2012 news release on EurekAlert,

Experienced ballet spectators with no physical expertise in ballet showed enhanced muscle-specific motor responses when watching live ballet, according to a Mar. 21 report in the open access journal PLoS ONE.

This result when watching such a formal dance as ballet is striking in comparison to the similar enhanced response the authors found in empathic observers when watching an Indian dance rich in hand gestures. This is important because it shows that motor expertise in the movements observed is not required to have enhanced neural motor responses when just watching dance performances.

The authors suggest that spectators covertly simulate the dance movements for styles that they regularly watch, causing the increased corticospinal excitability.

The article ‘Motor Simulation without Motor Expertise: Enhanced Corticospinal Excitability in Visually Experienced Dance Spectators‘ by Jola C, Abedian-Amiri A, Kuppuswamy A, Pollick FE, Grosbras M-H in PLoS ONE 7(3): e33343. doi:10.1371/journal.pone.0033343 is freely available for reading (open access).

I went searching for the Watching Dance Project website and found these images of dancers and a neuron, respectively,

From the Wtachng Dance Project website.

 

From the Watching Dance Project website.

According to the project’s About Us page,

‘Watching Dance: Kinesthetic Empathy’ uses audience research and neuroscience to explore how dance spectators respond to and identify with dance. It is a multidisciplinary project, involving collaboration across four institutions (University of Manchester, University of Glasgow, York St John University and Imperial College London).

The second neuroscience item for this posting is about listening to neurons. From the March 21, 2012 news release on EurekAlert,

Amateurs have a new tool for conducting simple neuroscience experiments in their own garage: the SpikerBox. As reported in the Mar. 21 issue of the open access journal PLoS ONE, the SpikerBox lets users amplify and listen to neurons’ electrical activity – like those in a cockroach leg or cricket torso – and is appropriate for use in middle or high school educational programs, or by amateurs.

The work was a project from Backyard Brains, a start-up company focused on developing neuroscience educational resources. In the paper, the authors, Timothy Marzullo and Gregory Gage, describe a sample experiment using a cockroach leg stuck with two needles and monitoring the electrical signals. They also provide instructions for using the SpikerBox to answer specific experimental questions, like how neurons carry information about touch, how the brain tells muscles to move, and how drugs affect neurons, and an online portal provides further instructional materials. These are just a few examples of the many ways this tool can be used.

“Our mission is to lower the barrier-to-entry for students interested in learning about the brain. We hope our manuscript finds its way into the hands of high school teachers around the world”, says Dr. Marzullo.

The article, The SpikerBox: A Low Cost, Open-Source BioAmplifier for Increasing Public Participation in Neuroscience Inquiry, by Timothy C. Marzullo and Gregory J. Gage can be found in PLoS ONE 7(3): e30837. doi:10.1371/journal.pone.0030837 and is freely available for reading (open access).

Backyard Brains can be found here along with the SpikerBox kit and other kits for sale and for use in your garage and backyard neuroscience experiments.

Care to commercialize graphene in the UK?

Tuesday, February 28th, 2012

The UK’s Engineering and Physical Sciences Research Council (EPSRC) has announced a call for proposals for research that is directly linked to commercializing graphene. From the Feb. 28, 2012 news item on Nanowerk,

The aim of the call, where there will be up to £20 million of funding available, is to focus research on manufacturing processes and technologies linked to graphene in order to accelerate the development and generation of novel devices, applications technologies and systems.

In 2010 the Nobel Prize for Physics was awarded to UK researchers Andre Geim and Kostya Novoselov from the University of Manchester, who demonstrated graphene in 2004. EPSRC has funded their work for over a decade.

The call is divided into two parts: research programmes and equipment bids. EPSRC is committing £10 million to the call, with up to £10 million more available by the Department for Business, Innovation and Skills (BIS) to fund the capital equipment as part of either research programmes or for equipment-only bids.

Proposals for research programmes should range between £1.5 million and £3 million and should seek to understand how to commercialise and enhance the ‘manufacturability’ of graphene as the material of choice. Programmes should have an emphasis on applications, strongly align with industry needs and foster an environment of collaboration across the UK. The programmes of research should also focus on developing people to stimulate the future sustainability of UK graphene engineering research and future commercialisation opportunities across a variety of sectors.

Proposals for equipment are to allow groups with existing capability in graphene research to help researchers advance the commercialisation of graphene and improve the emphasis on applications.

There’s a 10 pp. PDF description for the call, which includes gems like this, as well as, details about the call,

Recognising this opportunity, on 3 October 2011, the Chancellor (George Osborne, UK’s Chancellor of the Exchequer [roughly equivalent to a Minister of Finance]) pledged a £50M investment to establish the UK as a graphene research and technology ‘hub’ with the aim to capture the commercial benefits of graphene (http://www.epsrc.ac.uk/newsevents/news/2012/Pages/graphenehub.aspx). The chancellor stated “We will fund a national research programme that will take this Nobel prize-winning discovery from the British laboratory to the British factory floor…” “We’re going to get Britain making things again.” (p. 2)

There’s a six-page PDF called an Expression of Interest for interested parties to fill out. For anyone who experiences difficulties filling out PDF forms and/or submitting them, there is a set of guidelines.

Frankly, I found the description for eligibility in the EPSRC Funding Guide a little confusing but it seems a fairly safe guess that pretty much everyone involved in the proposed project, investigators, postdoctoral students, and research assistants must be resident in the UK.

It’s fascinating to track this graphene effort, which seems designed to lift the UK from its economic doldrums, from afar. It seems there’s some sort of announcement on this front on a weekly basis, at least (my most recent posting about these efforts is Feb. 21, 2012).

My experience with these kinds of announcements is that they are often recycled. For example, an announcement is made in Oct. 2011 about government funding for graphene research then months later, a research funding agency announces a call for proposals with references to the amount of research money available. Next on the agenda will be an announcement of the recipients for the grants. This practice can make it seem as if the second and third announcement are for new funds when it is money that was promised months before.

British royalty and graphene

Tuesday, February 21st, 2012

The UK’s graphene campaign is relentless (my most recent, previous comment on it was in a Feb. 6, 2012 posting). Now, they’ve brought royalty to the University of Manchester, according to a Feb. 20, 2012 news item by Cameron Chai on Azonano,

His Royal Highness, The Duke of York has made a visit to the University of Manchester to understand more about graphene and its commercializing research.

The original Feb. 17, 2012 news release from the University of Manchester about Prince Andrew’s visit notes,

In the afternoon, the Prince was invited to the Innovation Centre and met UMI3 CEO, Clive Rowland.   His Royal Highness visited UMI3 as part of his desire to see that the UK is recognised as the best place in the world for Science and Engineering.

[Clive said] “He is keen to see the University continue to develop its capabilities in this regard and promote its successes and products internationally. He is extremely enthusiastic about the potential of graphene and interested in the different applications and routes to market for it.

Given that the University of Manchester is part of a consortium competing for a 1 billion Euro funding prize for the GRAPHENE-CA FET (Future and Emerging Technologies) flagship project, this campaign is fascinating to observe. The question that arises: If this is what we can observe, what can they be doing behind closed doors?

More admiration for the UK’s graphene strategy

Monday, February 6th, 2012

Around the same time the UK government was announcing its latest  investment in graphene research (GBP 50 million) for a graphene hub at the University of Manchester (mentioned in my Feb. 2, 2012 posting), a research team at the University of Manchester was making its own graphene announcement. From the Feb. 2, 2012 news item on Nanowerk,

In a paper published this week in Science (“Field-Effect Tunneling Transistor Based on Vertical Graphene Heterostructures”), a Manchester team lead by Nobel laureates Professor Andre Geim and Professor Konstantin Novoselov has literally opened a third dimension in graphene research. Their research shows a transistor that may prove the missing link for graphene to become the next silicon.

Here’s why it’s exciting,

One of many potential applications of graphene is its use as the basic material for computer chips instead of silicon. This potential has alerted the attention of major chip manufactures, including IBM, Samsung, Texas Instruments and Intel. Individual transistors with very high frequencies (up to 300 GHz) have already been demonstrated by several groups worldwide.

The problem up until now has been this,

Unfortunately, those transistors cannot be packed densely in a computer chip because they leak too much current, even in the most insulating state of graphene. This electric current would cause chips to melt within a fraction of a second.

This problem has been around since 2004 when the Manchester researchers reported their Nobel-winning graphene findings and, despite a huge worldwide effort to solve it since then, no real solution has so far been offered.

Now the researchers have more or less solved the problem in the laboratory,

The University of Manchester scientists now suggest using graphene not laterally (in plane) – as all the previous studies did – but in the vertical direction. They used graphene as an electrode from which electrons tunnelled through a dielectric into another metal. This is called a tunnelling diode.

Then they exploited a truly unique feature of graphene – that an external voltage can strongly change the energy of tunnelling electrons. As a result they got a new type of a device – vertical field-effect tunnelling transistor in which graphene is a critical ingredient.

Dr Leonid Ponomarenko, who spearheaded the experimental effort, said: “We have proved a conceptually new approach to graphene electronics. Our transistors already work pretty well. I believe they can be improved much further, scaled down to nanometre sizes and work at sub-THz frequencies.”

I find the timing for the announcements rather interesting. The researchers at the University of Manchester make this exciting breakthrough, which is being published in Science magazine and publicized at roughly the same time that the UK government makes an announcement about funding for a graphene research hub at the University of Manchester. All of this just months prior to a European Union decision about which two flagship research projects (the graphene flagship project is one of six in contention and the UK has three research institutions including the University of Manchester participating in that consortium) will be receiving a 1 billion Euro prize Coincidence or conspiracy? I’m inclined to believe that there’s a just bit of strategy involved as I noted in my Feb. 2, 2012 posting about the ‘hub announcement’, the graphene flagship/consortium, and the strategy.
