Opportunity for companies to take a survey on risk management and nanotechnology

A June 8, 2015 news item on Nanowerk features a European Union (EU) Framework Programme 7 (FP7) nanotechnology risk management project and survey,

The EU FP7 Sustainable Nanotechnologies (SUN) project is based on the idea that the current knowledge on environmental and health risks of nanomaterials – while limited – can nevertheless guide nanomanufacturing to avoid liabilities if an integrated approach addressing the complete product lifecycle is applied. SUN aims to evaluate the risks along the supply chains of engineered nanomaterials and incorporate the results into tools and guidelines for sustainable nanomanufacturing.

A May 26, 2015 SUN press release by Stella Stoycheva, which originated the news item, provides more details,

… A key objective of  Sustainable Nanotechnologies (SUN) is to build the SUN Decision Support System (SUNDS) to facilitate safe and sustainable nanomanufacturing and risk management. It will integrate tools for ecological and human health risk assessment, lifecycle assessment, economic assessment and social impact assessment within a sustainability assessment framework. We are currently developing the Technological Alternatives and Risk Management Measures (TARMM) inventory and are looking for companies to fill in a short survey.

… We would appreciate responses from personnel of companies involved in nanotechnology-related activities who are familiar with the risk management practices.

You can go here to take the survey. The focus is on companies and there don’t seem to be any geographic requirements such as only EU companies can participate.

The use of graphene scanners in art conservation

A May 20, 2015 news item on phys.org describes a new method of examining art work without damaging it,

Museum curators, art restorers, archaeologists and the broader public will soon be able to learn much more about paintings and other historic objects, thanks to an EU project which has become a pioneer in non-invasive art exploration techniques, based on a graphene scanner.

Researchers working on INSIDDE [INtegration of cost-effective Solutions for Imaging, Detection, and Digitisation of hidden Elements in paintings], which received a EUR 2.9 million investment from FP7 ICT Research Programme, have developed a graphene scanner that can explore under the surface of a painting, or through the dirt covering an ancient object unearthed in an archaeological dig, without touching it.

‘As well as showing sketches or previous paintings that have remained hidden beneath a particular artwork, the scanner, together with post-processing techniques, will allow us to identify and distinguish brushstrokes to understand the creative process,’ explained Javier Gutiérrez, of Spanish technology company Treelogic, which is leading the project.

A May 19, 2015 CORDIS press release, which originated the news item, provides more details about the graphene scanner’s cabilities,

The challenge in this field is to develop advanced technologies that avoid damaging the artwork under examination. Solvents and their potential side effects are progressively being replaced by the likes of lasers, to removed dirt and varnish from paintings. Limestone-producing bacteria can be used to fill cracks in sculptures. INSIDDE is taking a step further in this direction by using terahertz, a frequency band lying between microwave and infrared in the electromagnetic spectrum.

Until graphene, considered to be one of the materials of the future, came along it was difficult to generate terahertz frequencies to acquire such detail. Graphene in this application acts as a frequency multiplier, allowing scientists to reveal previously hidden features such as brushstroke textures, pigments and defects, without harming the work.

Although X-ray and infrared reflectography are used elsewhere to carry out this type of study, they heat the object and cannot reach the intermediate layers between the gesso and the varnish in paintings, or other characteristic elements in ceramics. INSIDDE’s device, using terahertz frequency, works in these intermediate layers and does not heat the object.

In conjunction with a commercial scanner mapping the art’s upper layers, it can generate full 3D data from the object in a completely non-intrusive way and processes this data to extract and interpret features invisible to the naked eye, in a way that has never been done before.

INSIDDE is developing this technology to benefit the general public, too. The 2D and 3D digital models it is producing will be uploaded to the Europeana network and the project aims to make the results available through a smartphone and tablet app to be exploited by local and regional museums. The app is currently being trialled at one of the partners, the Asturias Fine Art Museum in Oviedo. It shows the different layers of the painting the visitor is looking at and provides additional information and audio.

The press release notes that the technology offers some new possibilities,

Although the scanner is still in its trial and calibration phase, the project participants have already unveiled some promising results. Marta Flórez, of the Asturias Fine Art Museum, explained: ‘Using the prototype, we have been able to distinguish clearly between different pigments, which in some cases will avoid having to puncture the painting in order to find out what materials the artist used.’

The prototype is also being validated with some recently unearthed 3rd Century pottery from the Stara Zagora regional history museum in Bulgaria. When the project ends in December 2015, one of the options the consortium is assessing is putting this cost-effective solution at the service of smaller local and regional museums without art restoration departments so that they too, like the bigger museums, can make important discoveries about their collections.

Outcomes for US-European Union bridging Nano environment, health, and safety (EHS) research workshop

According to Lynn Bergeson in an April 14, 2015 news item on Nanotechnology Now, a US-European Union (EU) workshop on nanosafety has published a document,

The National Nanotechnology Initiative (NNI) published on March 23, 2015, the outcomes of the March 12-13, 2015, joint workshop held by the U.S. and the European Union (EU), “Bridging NanoEHS Research Efforts.” …

A US National Nanotechnology Initiative (NNI) ??, ??, 2015 notice on the nano.gov site provides more details,

Workshop participants reviewed progress toward COR [communities of research] goals and objectives, shared best practices, and identified areas for cross-COR collaboration.  To address new challenges the CORs were realigned and expanded with the addition of a COR on nanotechnology characterization. The seven CORs now address:

Databases and Computational Modeling
Exposure through Product Life
Human Toxicity
Risk Assessment
Risk Management and Control

The CORs support the shared goal of responsible nanotechnology development as outlined in the U.S. National Nanotechnology Initiative EHS Research Strategy, and the research strategy of the EU NanoSafety Cluster. The CORs directly address several priorities described in the documents above, including the creation of a comprehensive nanoEHS knowledge base and international cooperation on the development of best practices and consensus standards.

The CORs are self-run, with technical support provided by the European Commission and the U.S. National Nanotechnology Coordination Office. Each Community has European and American co-chairs who convene meetings and teleconferences, guide the discussions, and set the group’s agenda. Participation in the CORs is free and open to any interested individuals. More information is available at www.us-eu.org.

The workshop was organized by the European Commission and the U.S. National Nanotechnology Initiative under the auspices of the agreement for scientific and technological cooperation between the European Union and the United States.

Coincidentally, I received an April 13, 2015 notice about the European Commission’s NanoSafety Cluster’s Spring 2015 newsletter concerning their efforts but found no mention of the ‘bridging workshop’. Presumably, information was not available prior to the newsletter’s deadline.

In my April 8, 2014 posting about a US proposed rule for reporting nanomaterials, I included information about the US and its efforts to promote or participate in harmonizing the nano situation internationally. Scroll down about 35% of the way to find information about the Canada-U.S. Regulatory Cooperation Council (RCC) Nanotechnology Initiative, the Organisation for Economic Cooperation and Development (OECD) effort, and the International Organization for Standardization (ISO) effort.

Converting light to electricity at femto speeds

This is a pretty remarkable (to me anyway) piece of research on speeding up the process of converting light to electricity. From an April 14, 2015 Institute of Photonic Science press release (also on EurekAlert but dated April 15, 2015),

The efficient conversion of light into electricity plays a crucial role in many technologies, ranging from cameras to solar cells. It also forms an essential step in data communication applications, since it allows for information carried by light to be converted into electrical information that can be processed in electrical circuits. Graphene is an excellent material for ultrafast conversion of light to electrical signals, but so far it was not known how fast graphene responds to ultrashort flashes of light.

The new device that the researchers developed is capable of converting light into electricity in less than 50 femtoseconds (a twentieth of a millionth of a millionth of a second). To do this, the researchers used a combination of ultrafast pulse-shaped laser excitation and highly sensitive electrical readout. As Klaas-Jan Tielrooij comments, “the experiment uniquely combined the ultrafast pulse shaping expertise obtained from single molecule ultrafast photonics with the expertise in graphene electronics. Facilitated by graphene’s nonlinear photo-thermoelectric response, these elements enabled the observation of femtosecond photodetection response times.”

The ultrafast creation of a photovoltage in graphene is possible due to the extremely fast and efficient interaction between all conduction band carriers in graphene. This interaction leads to a rapid creation of an electron distribution with an elevated electron temperature. Thus, the energy absorbed from light is efficiently and rapidly converted into electron heat. Next, the electron heat is converted into a voltage at the interface of two graphene regions with different doping. This photo-thermoelectric effect turns out to occur almost instantaneously, thus enabling the ultrafast conversion of absorbed light into electrical signals. As Prof. van Hulst states, “it is amazing how graphene allows direct non-linear detecting of ultrafast femtosecond (fs) pulses”.

The results obtained from the findings of this work, which has been partially funded by the EC Graphene Flagship, open a new pathway towards ultra-fast optoelectronic conversion. As Prof. Koppens comments, “Graphene photodetectors keep showing fascinating performances addressing a wide range of applications”.

NANoREG halfway through its project (Environment, Health & Safety) term

A March 18, 2015 news item on Nanowerk announces a third NANoReg newsletter marking the halfway point in the project’s term (Note: Links have been removed),

NANoREG is the first FP7 project to deliver the answers needed by regulators and legislators on EHS [Environment, Health & Safety] by linking them to a scientific evaluation of data and test methods.

Time wise, the NANoREG project is now halfway. After setting the basic conditions for its R&D work, the project now focuses on the generation of reliable and comparable experimental data on the EHS aspects of the selected NANoREG nanomaterials. These data will form the basis for the main “end products” of the NANoREG project: the Regulatory Framework and the NANoREG Toolbox. Highlights of this experimental work and results will be shared with you in this 3rd NANoREG Newsletter (pdf).

The editorial for the 3rd issue of the NANoREG newsletter, which seems to have originated the news item, describes upcoming initiatives,

The Regulatory Framework and the NANoREG Toolbox just mentioned will be developed in close cooperation with organisations involved in standardisation and in the regulatory aspects of nanomaterials like ECHA [European Chemicals Agency], OECD [Organization for Economic Cooperation and Development], CEN [European Committee for Standardization] and ISO [International Standards Organization]. The results of other EU FP7 [Framework Programme 7] and H2020 [Horizon 2020] [research funding] projects will also be taken into account when developing these products. One of these projects is the H2020 project NANoREG II that focuses on Safe by design and that will start in the 2nd or 3rd quarter of 2015.

The coordinated and integrated approach in developing the Framework and the NANoREG Toolbox is one of the main elements of the H2020 funded Coordination and Support Action (CSA) “ProSafe” that recently had its Kick-Off meeting in Aix-en-Provence, France. Just like NANoREG this CSA is coordinated by the Dutch Ministry of Infrastructure and the Environment and as such executed by me. Other elements of this CSA are – among others – the expansions of the involvement of EU and non-EU countries in the NANoREG project in order to broaden the platform of support for the NANoREG results world-wide (“NANoREG+”), the exploitation of synergies between the NANoREG project and other “nanosafety” projects and data management.

The outcome of the CSA will be a White Paper that can be used by policy makers, regulators and industry to establish methods for measuring and assessing the EHS aspects of nanomaterials and that will give guidance to industry how to implement “safe by design“. A forerunner of the White Paper will be subject of a three days scientific conference to be held at the end of 2016. It will include the results of the NANoREG project, the results of the evaluation of EHS data available at the OECD and results from other sources. After consulting Risk assessors and policymakers, the White Paper will be published in the first quarter of 2017.

This project has reached out beyond Europe for partners (from the editorial for the 3rd NANoREG newsletter),

It is quite a challenge we face. Given the expertise and scientific authority of our partners, including the Czech-,Brazilian- and South Korean parties that recently joined the NANoREG project, I am confident however that we will succeed in reaching our goal: creating a solid basis for a balanced combination of nanosafety and innovation that will be beneficial to society.

I hope NANoREG is successful with its goal of “creating a solid basis for a balanced combination of nanosafety and innovation that will be beneficial to society.”

I last wrote about NANoREG in a March 21, 2014 posting.

Nanomedicine living up to its promise?

Michael Berger has written a March 10, 2015 Nanowerk spotlight article reviewing nanomedicine’s  progress or lack thereof (Note: Links have been removed),

In early 2003, the European Science Foundation launched its Scientific Forward Look on Nanomedicine, a foresight study (report here ;pdf) and in 2004, the U.S. National Institute[s] of Health (NIH) published its Roadmap (now Common Fund) of the Nanomedicine Initiative. This program began in 2005 with a national network of eight Nanomedicine Development Centers. Now, in the second half of this 10-year program, the four centers best positioned to effectively apply their findings to translational studies were selected to continue receiving support.

A generally accepted definition of nanomedicine refers to highly specific medical intervention at the molecular scale for curing disease or repairing damaged tissues, such as bone, muscle, or nerve.

Much of Berger’s article is based on Subbu Venkatraman’s, Director of the NTU (Nanyang Technological University)-Northwestern Nanomedicine Institute in Singapore, paper, Has nanomedicine lived up to its promise?, 2014 Nanotechnology 25 372501 doi:10.1088/0957-4484/25/37/372501 (Note: Links have been removed),

… Historically, the approval of Doxil as the very first nanotherapeutic product in 1995 is generally regarded as the dawn of nanomedicine for human use. Since then, research activity in this area has been frenetic, with, for example, 2000 patents being generated in 2003, in addition to 1200 papers [2]. In the same time period, a total of 207 companies were involved in developing nanomedicinal products in diagnostics, imaging, drug delivery and implants. About 38 products loosely classified as nanomedicine products were in fact approved by 2004. Out of these, however, a number of products (five in all) were based on PEG-ylated proteins, which strictly speaking, are not so much nanomedicine products as molecular therapeutics. Nevertheless, the promise of nanomedicine was being translated into funding for small companies, and into clinical success, so that by 2013, the number of approved products had reached 54 in all, with another 150 in various stages of clinical trials [3]. The number of companies and institutions had risen to 241 (including research centres that were working on nanomedicine). A PubMed search on articles relating to nanomedicine shows 7400 hits over 10 years, of which 1874 were published in 2013 alone. Similarly, the US patent office database shows 409 patents (since 1976) that were granted in nanomedicine, with another 679 applications awaiting approval. So judging by research activity and funding the field of nanomedicine has been very fertile; however, when we use the yardstick of clinical success and paradigm shifts in treatment, the results appear more modest.

Both Berger’s spotlight article and Venkatraman’s review provide interesting reading and neither is especially long.

2014 food and nanotechnologies report from the European Food Safety Authority

A Feb. 27, 2015 news item on Nanowerk announced the latest annual report on food and nanotechnologies from the European Food Safety Authority (EFSA),

In accordance with European Food Safety Authority (EFSA)’s strategy for cooperation and networking with Member States, a Network for Risk Assessment of Nanotechnologies in Food and Feed was established in 2010. The overall goals of this Network are to facilitate harmonisation of assessment practices and methodologies; to enhance exchange of information and data between EFSA and MS; and to achieve synergies in risk assessment activities. The Annual reports of the Network inform the public and the EFSA Advisory Forum about its specific activities and achievements.

The summary for the EFSA Scientific Network of Risk Assessment of Nanotechnologies in Food and Feed1 for 2014 Technical Report offers more details (Note: A link has been removed),

The Network is composed of representatives from 21 Member States and Norway. In addition, observers to this Network represent the Former Yugoslav Republic of Macedonia, Turkey and Montenegro. There is also representation from the European Commission (DGSANTE and JRC), from the EFSA Scientific Committee and the relevant Units/Panels.

During 2014, the Network followed-up on its priority areas and contributed to the making of inventory lists of applications of Nanomaterials already present in the food/feed chain.

At its 2014 meeting the Network focussed again on updates of research results from toxicological studies relevant for the oral route of exposure. Member States representatives presented relevant studies. The type of nanomaterials that are now occurring in the food/feed chain are mainly Titanium dioxide (TiO2) and Synthetic Amorphous Silica (SAS). The evidence bases for oral toxicity and for conducting comprehensive risk assessments of these two materials is building up, but more research remains needed. Challenges to draw firm risk assessment conclusions reside in (1) the intake estimation (2) the possible worst-case absorption and the dose-dependence of absorption (3) the potential irrelevance of high dose oral toxicity studies for risk assessment (4) the extrapolation of kinetic data from rat to man (5) the nanoparticle determination in tissues, and (6) the many differences between the types of nanoforms of one nanomaterial (e.g. in kinetics and toxicity). Some differences in behaviour of different nanoforms have been observed, but there is no clear overview. A new issue of concern is that absorption is not linear with dose: high dose studies are often used for tox testing for estimation of safe dose, while the high dose may result in aggregation, agglomeration, gelation and as a consequence dose-dependent absorption.

Challenges also remain to exist regarding the technical aspects for considering a material as a nanomaterial (NM) for the regulatory purpose of food labelling. The NanoDefine project (FP7) is expected to deliver by 2017 an implementable test-scheme for regulatory purposes to distinguish nano from non-nano.

The Network agreed that regardless the current challenges and regardless the % of nanoforms in the bulk material (particle size% or mass%), EFSA should assess the nano-fraction, no matter how small. Food law, as being implemented by the EFSA Panels is covering nanomaterials. Nanomaterials are addressed mainly by cross-referring to the Guidance on the risk assessment of the application of nanoscience and nanotechnologies in the food and feed chain (EFSA Scientific Committee, 2011 http://www.efsa.europa.eu/en/efsajournal/doc/2140.pdf).

Europe’s search for raw materials and hopes for nanotechnology-enabled solutions

A Feb. 27, 2015 news item on Nanowerk highlights the concerns over the availability of raw materials and European efforts to address those concerns,

Critical raw materials’ are crucial to many European industries but they are vulnerable to scarcity and supply disruption. As such, it is vital that Europe develops strategies for meeting the demand for raw materials. One such strategy is finding methods or substances that can replace the raw materials that we currently use. With this in mind, four EU projects working on substitution in catalysis, electronics and photonics presented their work at the Third Innovation Network Workshop on substitution of Critical Raw Materials hosted by the CRM_INNONET project in Brussels earlier this month [February 2015].

A Feb. 26, 2015 CORDIS press release, which originated the news item, goes on to describe four European Union projects working on nanotechnology-enabled solutions,


NOVACAM, a coordinated Japan-EU project, aims to develop catalysts using non-critical elements designed to unlock the potential of biomass into a viable energy and chemical feedstock source.

The project is using a ‘catalyst by design’ approach for the development of next generation catalysts (nanoscale inorganic catalysts), as NOVACAM project coordinator Prof. Emiel Hensen from Eindhoven University of Technology in the Netherlands explained. Launched in September 2013, the project is developing catalysts which incorporate non-critical metals to catalyse the conversion of lignocellulose into industrial chemical feedstocks and bio-fuels. The first part of the project has been to develop the principle chemistry while the second part is to demonstrate proof of process. Prof. Hensen predicts that perhaps only two of three concepts will survive to this phase.

The project has already made significant progress in glucose and ethanol conversion, according to Prof. Hensen, and has produced some important scientific publications. The consortium is working with and industrial advisory board comprising Shell in the EU and Nippon Shokubai in Japan.


The FREECATS project, presented by project coordinator Prof. Magnus Rønning from the Norwegian University of Science and Technology, has been working over the past three years to develop new metal-free catalysts. These would be either in the form of bulk nanomaterials or in hierarchically organised structures – both of which would be capable of replacing traditional noble metal-based catalysts in catalytic transformations of strategic importance.

Prof. Magnus Rønning explained that the application of the new materials could eliminate the need for the use for platinum group metals (PGM) and rare earth metals – in both cases Europe is very reliant on other countries for these materials. Over the course of its research, FREECATS targeted three areas in particular – fuel cells, the production of light olefins and water and wastewater purification.

By working to replace the platinum in fuel cells, the project is supporting the EU’s aim of replacing the internal combustion engine by 2050. However, as Prof. Rønning noted, while platinum has been optimized for use over several decades, the materials FREECATS are using are new and thus come with their new challenges which the project is addressing.


Prof. Atsufumi Hirohata of the University of York in the United Kingdom, project coordinator of HARFIR, described how the project aims to discover an antiferromagnetic alloy that does not contain the rare metal Iridium. Iridium is becoming more and more widely used in numerous spin electronic storage devices, including read heads in hard disk drives. The world supply depends on Platinum ore that comes mainly from South Africa. The situation is much worse than for other rare earth elements as the price has been shooting up over recent years, according to Prof. Hirohata.

The HARFIR team, divided between Europe and Japan, aims to replace Iridium alloys with Heusler alloys. The EU team, led by Prof. Hirohata, has been working on the preparation of polycrystalline and epitaxial thin films of Heusler Alloys, with the material design led by theoretical calculations. The Japanese team, led by Prof. Koki Takanashi at Tohoku University, is meanwhile working on the preparation of epitaxial thin films, measurements of fundamental properties and structural/magnetic characterisation by neutron and synchrotron x-ray beams.

One of the biggest challenges has been that Heusler alloys have a relatively complicated atomic structure. In terms of HARFIR’s work, if any atomic disordering at the edge of nanopillar devices, the magnetic properties that are needed are lost. The team is exploring solutions to this challenge.


Prof. of Esko Kauppinen Aalto University in Finland closed off the first session of the morning with his presentation of the IRENA project. Launched in September 2013, the project will run until mid 2017 working towards the aim of developing high performance materials, specifically metallic and semiconducting single-walled carbon nanotube (SWCNT) thin films to completely eliminate the use of the critical metals in electron devices. The ultimate aim is to replace Indium in transparent conducting films, and Indium and Gallium as a semiconductor in thin film field effect transistors (TFTs).

The IRENA team is developing an alternative that is flexible, transparent and stretchable so that it can meet the demands of the electronics of the future – including the possibility to print electronics.

IRENA involves three partners from Europe and three from Japan. The team has expertise in nanotube synthesis, thin film manufacturing and flexible device manufacturing, modelling of nanotube growth and thin film charge transport processes, and the project has benefitted from exchanges of team members between institutions. One of the key achievements so far is that the project has succeeded in using a nanotube thin film for the first time as the both the electrode and hole blocking layer in an organic solar cell.

You’ll note that Japan is a partner in all of these projects. In all probability, these initiatives have something to do with rare earths which are used in much of today’s electronics technology and Japan is sorely lacking in those materials. China, by comparison, has dominated the rare earths export industry and here’s an excerpt from my Nov. 1, 2013 posting where I outline the situation (which I suspect hasn’t changed much since),

As for the short supply mentioned in the first line of the news item, the world’s largest exporter of rare earth elements at 90% of the market, China, recently announced a cap according to a Sept. 6, 2013 article by David Stanway for Reuters. The Chinese government appears to be curtailing exports as part of an ongoing, multi-year strategy. Here’s how Cientifica‘s (an emerging technologies consultancy, etc.) white paper (Simply No Substitute?) about critical materials published in 2012 (?), described the situation,

Despite their name, REE are not that rare in the Earth’s crust. What has happened in the past decade is that REE exports from China undercut prices elsewhere, leading to the closure of mines such as the Mountain Pass REE mine in California. Once China had acquired a dominant market position, prices began to rise. But this situation will likely ease. The US will probably begin REE production from the Mountain Pass mine later in 2012, and mines in other countries are expected to start operation soon as well.

Nevertheless, owing to their broad range of uses REE will continue to exert pressures on their supply – especially for countries without notable REE deposits. This highlights two aspects of importance for strategic materials: actual rarity and strategic supply issues such as these seen for REE. Although strategic and diplomatic supply issues may have easier solutions, their consideration for manufacturing industries will almost be the same – a shortage of crucial supply lines.

Furthermore, as the example of REE shows, the identification of long-term supply problems can often be difficult, and not every government has the same strategic foresight that the Chinese demonstrated. And as new technologies emerge, new elements may see an unexpected, sudden demand in supply. (pp. 16-17)

Meanwhile, in response to China’s decision to cap its 2013 REE exports, the Russian government announced a $1B investment to 2018 in rare earth production,, according to a Sept. 10, 2013 article by Polina Devitt for Reuters.

I’m not sure you’ll be able to access Tim Harper’s white paper as he is now an independent, serial entrepreneur. I most recently mentioned him in relation to his articles (on Azonano) about the nanotechnology scene in a Feb. 12, 2015 posting where you’ll also find contact details for him.

Nanomaterials, the European Commission, and functionality

A Feb. 17, 2015 news item on Nanowerk features a special thematic issue of Science for Environment Policy, a free news and information service published by the European
Commission’s Directorate-General Environment, which provides the latest environmental policy-relevant research findings (Note: A link has been removed),

Nanomaterials – at a scale of one thousand times smaller than a millimetre – offer the promise of radical technological development. Many of these will improve our quality of life, and develop our economies, but all will be measured against the overarching principle that we do not make some error, and harm ourselves and our environment by exposure to new forms of hazard. This Thematic Issue (“Nanomaterials’ functionality”; free pdf download) explores recent developments in nanomaterials research, and possibilities for safe, practical and resource-efficient applications.

You can find Nanomaterials’ functionality thematic issue here; the issue includes.

Several articles in this Thematic Issue illustrate how nanotechnology is likely to further revolutionise that arena, for example in capturing sunlight and turning it into usable electrical energy. The article ‘Solar cell efficiency boosted with pine tree-like nanotube needle’, describes how light collected from the sun can be bounced around many times inside a nanostructure to improve the chance of it exciting electrons, and ‘Nanotechnology cuts costs and improves efficiency of photovoltaic cells’ shows how electrons that are released can be captured by the large surface area of ‘nano-tree like’ anodes. Together these ensure that more of the sunlight is transformed to captured electrons and electrical power. The article ‘New energy-efficient manufacture of perovskite solar cells’ goes further, and suggests that the existing titanium dioxide that is currently used in solar cells could be replaced by perovskites, yielding quite dramatic improvements in energy conversion, at low device fabrication costs. …

The article ‘New quantum dot process could lead to super-efficient light-producing technology’ describes how anisotropic (elongated, non-spherical) indium-gallenium nitride quantum dots, or proximity to an anisotropic surface, can lead quantum dots to emit polarised light, potentially enabling 3D television screens, optical computers and other applications, at much lower cost. ‘The potential of new building block-like nanomaterials: van der Waals heterostructures’ and ‘Graphene’s health effects summarised in new guide’ touch on the possibility of engineering ‘building block-crystals’ by arranging different 2D nanostructures such as graphene into low dimension crystals, which allows us, for example, to lower the loss of energy in transmitting electricity. There are also quite novel directions underpinning ‘green nanochemistry’ — illustrated by the potential of silk-based electron-beam resists (in the article ‘Making nano-scale manufacturing eco-friendly with silk’) — to be eco-friendly, and have new functionalities.

… [p. 3 PDF]

In addition to highlighting various research areas by mentioning articles included the issue, the editorial makes its case for commercializing nanomaterials and for the European establishment’s precautionary approach to doing so,

European institutions and organisations have been at the forefront of efforts to ensure safe and practical implementation of nanotechnology. Significant efforts have been made to address knowledge gaps through research, the financing of responsible innovation, and the upgrading of the regulatory framework to render it capable of addressing the new challenges. There are solid reasons for institutional attention to the issues. Succinctly put, the passing around and modification of natural nanoparticles and macromolecules (for example, proteins) within our bodies is the foundation of much of life. In doing so we regulate and send signals between cells and organs. It is therefore appropriate that questions should be asked about engineered nanoparticles and how they interact with us, and whether they could lead to unforeseen hazards. Those are substantive issues, and answering them well will support the creative drive towards real innovation for many decades to come, and honour our commitments to future generations. [p. 4 PDF]

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.
