A solar, self-charging supercapacitor for wearable technology

Ravinder Dahiya, Carlos García Núñez, and their colleagues at the University of Glasgow (Scotland) strike again (see my May 10, 2017 posting for their first ‘solar-powered graphene skin’ research announcement). Last time it was all about robots and prosthetics, this time they’ve focused on wearable technology according to a July 18, 2018 news item on phys.org,

A new form of solar-powered supercapacitor could help make future wearable technologies lighter and more energy-efficient, scientists say.

In a paper published in the journal Nano Energy, researchers from the University of Glasgow’s Bendable Electronics and Sensing Technologies (BEST) group describe how they have developed a promising new type of graphene supercapacitor, which could be used in the next generation of wearable health sensors.

A July 18, 2018 University of Glasgow press release, which originated the news item, explains further,

Currently, wearable systems generally rely on relatively heavy, inflexible batteries, which can be uncomfortable for long-term users. The BEST team, led by Professor Ravinder Dahiya, have built on their previous success in developing flexible sensors by developing a supercapacitor which could power health sensors capable of conforming to wearer’s bodies, offering more comfort and a more consistent contact with skin to better collect health data.

Their new supercapacitor uses layers of flexible, three-dimensional porous foam formed from graphene and silver to produce a device capable of storing and releasing around three times more power than any similar flexible supercapacitor. The team demonstrated the durability of the supercapacitor, showing that it provided power consistently across 25,000 charging and discharging cycles.

They have also found a way to charge the system by integrating it with flexible solar powered skin already developed by the BEST group, effectively creating an entirely self-charging system, as well as a pH sensor which uses wearer’s sweat to monitor their health.

Professor Dahiya said: “We’re very pleased by the progress this new form of solar-powered supercapacitor represents. A flexible, wearable health monitoring system which only requires exposure to sunlight to charge has a lot of obvious commercial appeal, but the underlying technology has a great deal of additional potential.

“This research could take the wearable systems for health monitoring to remote parts of the world where solar power is often the most reliable source of energy, and it could also increase the efficiency of hybrid electric vehicles. We’re already looking at further integrating the technology into flexible synthetic skin which we’re developing for use in advanced prosthetics.” [emphasis mine]

In addition to the team’s work on robots, prosthetics, and graphene ‘skin’ mentioned in the May 10, 2017 posting the team is working on a synthetic ‘brainy’ skin for which they have just received £1.5m funding from the Engineering and Physical Science Research Council (EPSRC).

Brainy skin

A July 3, 2018 University of Glasgow press release discusses the proposed work in more detail,

A robotic hand covered in ‘brainy skin’ that mimics the human sense of touch is being developed by scientists.

University of Glasgow’s Professor Ravinder Dahiya has plans to develop ultra-flexible, synthetic Brainy Skin that ‘thinks for itself’.

The super-flexible, hypersensitive skin may one day be used to make more responsive prosthetics for amputees, or to build robots with a sense of touch.

Brainy Skin reacts like human skin, which has its own neurons that respond immediately to touch rather than having to relay the whole message to the brain.

This electronic ‘thinking skin’ is made from silicon based printed neural transistors and graphene – an ultra-thin form of carbon that is only an atom thick, but stronger than steel.

The new version is more powerful, less cumbersome and would work better than earlier prototypes, also developed by Professor Dahiya and his Bendable Electronics and Sensing Technologies (BEST) team at the University’s School of Engineering.

His futuristic research, called neuPRINTSKIN (Neuromorphic Printed Tactile Skin), has just received another £1.5m funding from the Engineering and Physical Science Research Council (EPSRC).

Professor Dahiya said: “Human skin is an incredibly complex system capable of detecting pressure, temperature and texture through an array of neural sensors that carry signals from the skin to the brain.

“Inspired by real skin, this project will harness the technological advances in electronic engineering to mimic some features of human skin, such as softness, bendability and now, also sense of touch. This skin will not just mimic the morphology of the skin but also its functionality.

“Brainy Skin is critical for the autonomy of robots and for a safe human-robot interaction to meet emerging societal needs such as helping the elderly.”

This latest advance means tactile data is gathered over large areas by the synthetic skin’s computing system rather than sent to the brain for interpretation.

With additional EPSRC funding, which extends Professor Dahiya’s fellowship by another three years, he plans to introduce tactile skin with neuron-like processing. This breakthrough in the tactile sensing research will lead to the first neuromorphic tactile skin, or ‘brainy skin.’

To achieve this, Professor Dahiya will add a new neural layer to the e-skin that he has already developed using printing silicon nanowires.

Professor Dahiya added: “By adding a neural layer underneath the current tactile skin, neuPRINTSKIN will add significant new perspective to the e-skin research, and trigger transformations in several areas such as robotics, prosthetics, artificial intelligence, wearable systems, next-generation computing, and flexible and printed electronics.”

The Engineering and Physical Sciences Research Council (EPSRC) is part of UK Research and Innovation, a non-departmental public body funded by a grant-in-aid from the UK government.

EPSRC is the main funding body for engineering and physical sciences research in the UK. By investing in research and postgraduate training, the EPSRC is building the knowledge and skills base needed to address the scientific and technological challenges facing the nation.

Its portfolio covers a vast range of fields from healthcare technologies to structural engineering, manufacturing to mathematics, advanced materials to chemistry. The research funded by EPSRC has impact across all sectors. It provides a platform for future UK prosperity by contributing to a healthy, connected, resilient, productive nation.

It’s fascinating to note how these pieces of research fit together for wearable technology and health monitoring and creating more responsive robot ‘skin’ and, possibly, prosthetic devices that would allow someone to feel again.

The latest research paper

Getting back the solar-charging supercapacitors mentioned in the opening, here’s a link to and a citation for the team’s latest research paper,

Training drugs

This summarizes some of what’s happening in nanomedicine and provides a plug (boost) for the  University of Cambridge’s nanotechnology programmes (from a June 26, 2017 news item on Nanowerk),

Nanotechnology is creating new opportunities for fighting disease – from delivering drugs in smart packaging to nanobots powered by the world’s tiniest engines.

Chemotherapy benefits a great many patients but the side effects can be brutal.
When a patient is injected with an anti-cancer drug, the idea is that the molecules will seek out and destroy rogue tumour cells. However, relatively large amounts need to be administered to reach the target in high enough concentrations to be effective. As a result of this high drug concentration, healthy cells may be killed as well as cancer cells, leaving many patients weak, nauseated and vulnerable to infection.

One way that researchers are attempting to improve the safety and efficacy of drugs is to use a relatively new area of research known as nanothrapeutics to target drug delivery just to the cells that need it.

Professor Sir Mark Welland is Head of the Electrical Engineering Division at Cambridge. In recent years, his research has focused on nanotherapeutics, working in collaboration with clinicians and industry to develop better, safer drugs. He and his colleagues don’t design new drugs; instead, they design and build smart packaging for existing drugs.

The University of Cambridge has produced a video interview (referencing a 1966 movie ‘Fantastic Voyage‘ in its title)  with Sir Mark Welland,

A June 23, 2017 University of Cambridge press release, which originated the news item, delves further into the topic of nanotherapeutics (nanomedicine) and nanomachines,

Nanotherapeutics come in many different configurations, but the easiest way to think about them is as small, benign particles filled with a drug. They can be injected in the same way as a normal drug, and are carried through the bloodstream to the target organ, tissue or cell. At this point, a change in the local environment, such as pH, or the use of light or ultrasound, causes the nanoparticles to release their cargo.

Nano-sized tools are increasingly being looked at for diagnosis, drug delivery and therapy. “There are a huge number of possibilities right now, and probably more to come, which is why there’s been so much interest,” says Welland. Using clever chemistry and engineering at the nanoscale, drugs can be ‘taught’ to behave like a Trojan horse, or to hold their fire until just the right moment, or to recognise the target they’re looking for.

“We always try to use techniques that can be scaled up – we avoid using expensive chemistries or expensive equipment, and we’ve been reasonably successful in that,” he adds. “By keeping costs down and using scalable techniques, we’ve got a far better chance of making a successful treatment for patients.”

In 2014, he and collaborators demonstrated that gold nanoparticles could be used to ‘smuggle’ chemotherapy drugs into cancer cells in glioblastoma multiforme, the most common and aggressive type of brain cancer in adults, which is notoriously difficult to treat. The team engineered nanostructures containing gold and cisplatin, a conventional chemotherapy drug. A coating on the particles made them attracted to tumour cells from glioblastoma patients, so that the nanostructures bound and were absorbed into the cancer cells.

Once inside, these nanostructures were exposed to radiotherapy. This caused the gold to release electrons that damaged the cancer cell’s DNA and its overall structure, enhancing the impact of the chemotherapy drug. The process was so effective that 20 days later, the cell culture showed no evidence of any revival, suggesting that the tumour cells had been destroyed.

While the technique is still several years away from use in humans, tests have begun in mice. Welland’s group is working with MedImmune, the biologics R&D arm of pharmaceutical company AstraZeneca, to study the stability of drugs and to design ways to deliver them more effectively using nanotechnology.

“One of the great advantages of working with MedImmune is they understand precisely what the requirements are for a drug to be approved. We would shut down lines of research where we thought it was never going to get to the point of approval by the regulators,” says Welland. “It’s important to be pragmatic about it so that only the approaches with the best chance of working in patients are taken forward.”

The researchers are also targeting diseases like tuberculosis (TB). With funding from the Rosetrees Trust, Welland and postdoctoral researcher Dr Íris da luz Batalha are working with Professor Andres Floto in the Department of Medicine to improve the efficacy of TB drugs.

Their solution has been to design and develop nontoxic, biodegradable polymers that can be ‘fused’ with TB drug molecules. As polymer molecules have a long, chain-like shape, drugs can be attached along the length of the polymer backbone, meaning that very large amounts of the drug can be loaded onto each polymer molecule. The polymers are stable in the bloodstream and release the drugs they carry when they reach the target cell. Inside the cell, the pH drops, which causes the polymer to release the drug.

In fact, the polymers worked so well for TB drugs that another of Welland’s postdoctoral researchers, Dr Myriam Ouberaï, has formed a start-up company, Spirea, which is raising funding to develop the polymers for use with oncology drugs. Ouberaï is hoping to establish a collaboration with a pharma company in the next two years.

“Designing these particles, loading them with drugs and making them clever so that they release their cargo in a controlled and precise way: it’s quite a technical challenge,” adds Welland. “The main reason I’m interested in the challenge is I want to see something working in the clinic – I want to see something working in patients.”

Could nanotechnology move beyond therapeutics to a time when nanomachines keep us healthy by patrolling, monitoring and repairing the body?

Nanomachines have long been a dream of scientists and public alike. But working out how to make them move has meant they’ve remained in the realm of science fiction.

But last year, Professor Jeremy Baumberg and colleagues in Cambridge and the University of Bath developed the world’s tiniest engine – just a few billionths of a metre [nanometre] in size. It’s biocompatible, cost-effective to manufacture, fast to respond and energy efficient.

The forces exerted by these ‘ANTs’ (for ‘actuating nano-transducers’) are nearly a hundred times larger than those for any known device, motor or muscle. To make them, tiny charged particles of gold, bound together with a temperature-responsive polymer gel, are heated with a laser. As the polymer coatings expel water from the gel and collapse, a large amount of elastic energy is stored in a fraction of a second. On cooling, the particles spring apart and release energy.

The researchers hope to use this ability of ANTs to produce very large forces relative to their weight to develop three-dimensional machines that swim, have pumps that take on fluid to sense the environment and are small enough to move around our bloodstream.

Working with Cambridge Enterprise, the University’s commercialisation arm, the team in Cambridge’s Nanophotonics Centre hopes to commercialise the technology for microfluidics bio-applications. The work is funded by the Engineering and Physical Sciences Research Council and the European Research Council.

“There’s a revolution happening in personalised healthcare, and for that we need sensors not just on the outside but on the inside,” explains Baumberg, who leads an interdisciplinary Strategic Research Network and Doctoral Training Centre focused on nanoscience and nanotechnology.

“Nanoscience is driving this. We are now building technology that allows us to even imagine these futures.”

I have featured Welland and his work here before and noted his penchant for wanting to insert nanodevices into humans as per this excerpt from an April 30, 2010 posting,
Getting back to the Cambridge University video, do go and watch it on the Nanowerk site. It is fun and very informative and approximately 17 mins. I noticed that they reused part of their Nokia morph animation (last mentioned on this blog here) and offered some thoughts from Professor Mark Welland, the team leader on that project. Interestingly, Welland was talking about yet another possibility. (Sometimes I think nano goes too far!) He was suggesting that we could have chips/devices in our brains that would allow us to think about phoning someone and an immediate connection would be made to that person. Bluntly—no. Just think what would happen if the marketers got access and I don’t even want to think what a person who suffers psychotic breaks (i.e., hearing voices) would do with even more input. Welland starts to talk at the 11 minute mark (I think). For an alternative take on the video and more details, visit Dexter Johnson’s blog, Nanoclast, for this posting. Hint, he likes the idea of a phone in the brain much better than I do.

I’m not sure what could have occasioned this latest press release and related video featuring Welland and nanotherapeutics other than guessing that it was a slow news period.

Are there any leaders in the ‘graphene race’?

Tom Eldridge, a director and co-founder of Fullerex, has written a Jan. 5, 2017 essay titled: Is China still leading the graphene race? for Nanotechnology Now. Before getting to the essay, here’s a bit more about Fullerex and Tom Eldridge’s qualifications. From Fullerex’s LinkedIn description,

As a result, Fullerex has the strong management composition that allows the company to support the growth of the nascent and highly promising nanomaterials industry. Fullerex is a flexible company with drive, enthusiasm and experience, committed to aiding the development of this market.

Getting back to the matter at hand, that’s a rather provocative title for Tom Eldridge’s essay,. given that he’s a Brit and (I believe) the Brits viewed themselves as leaders in the ‘graphene race’ but he offers a more nuanced analysis than might be expected from the title. First, the patent landscape (from Eldridge’s Jan. 5, 2017 essay),

As competition to exploit the “wonder material” has intensified around the world, detailed reports have so far been published which set out an in-depth depiction of the global patent landscape for graphene, notably from CambridgeIP and the UK Intellectual Property Office, in 2013 and 2015 respectively. Ostensibly the number of patents and patent applications both indicated that China was leading the innovation in graphene technology. However, on closer inspection it became less clear as to how closely the patent figures themselves reflect actual progress and whether this will translate into real economic impact. Some of the main reasons to be doubtful included:

– 98% of the Chinese patent applications only cover China, so therefore have no worldwide monopoly.
– A large number of the Chinese patents are filed in December, possibly due to demand to meet patent quotas. The implication being that the patent filings follow a politically driven agenda, rather than a purely innovation or commercially driven agenda.
– In general, inventors could be more likely to file for patent protection in some countries rather than others e.g. for tax purposes. Which therefore does not give a truly accurate picture of where all the actual research activity is based.
– Measuring the proportion of graphene related patents to overall patents is more indicative of graphene specialisation, which shows that Singapore has the largest proportion of graphene patents, followed by China, then South Korea.

(Intellectual Property Office, 2015), (Ellis, 2015), (CambridgeIP, 2013)

Then, there’s the question of production,

Following the recent launch of the latest edition of the Bulk Graphene Pricing Report, which is available exclusively through The Graphene Council, Fullerex has updated its comprehensive list of graphene producers worldwide, and below is a summary of the number of graphene producers by country in 2017.

Summary Table Showing the Number of Graphene Producers by Country and Region

The total number of graphene producers identified is 142, across 27 countries. This research expands upon previous surveys of the graphene industry, such as the big data analysis performed by Nesta in 2015 (Shapira, 2015). The study by Nesta [formerly  NESTA, National Endowment for Science, Technology and the Arts) is an independent charity that works to increase the innovation capacity of the UK; see Wikipedia here for more about NESTA] revealed 65 producers throughout 16 countries but was unable to glean accurate data on producers in Asia, particularly China.

As we can now see however from the data collected by Fullerex, China has the largest number of graphene producers, followed by the USA, and then the UK.

In addition to having more companies active in the production and sale of graphene than any other country, China also holds about 2/3rds of the global production capacity, according to Fullerex.

Eldridge goes on to note that the ‘graphene industry’ won’t truly grow and develop until there are substantive applications for the material. He also suggests taking another look at the production figures,

As with the patent landscape, rather than looking at the absolute figures, we can review the numbers in relative terms. For instance, if we normalise to account for the differences in the size of each country, by looking at the number of producers as a proportion of GDP, we see the following: Spain (7.18), UK (4.48), India (3.73), China (3.57), Canada (3.28) [emphasis mine], USA (1.79) (United Nations, 2013).

Unsurprisingly, each leading country has a national strategy for economic development which involves graphene prominently.

For instance, The Spanish Council for Scientific Research has lent 9 of its institutes along with 10 universities and other public R&D labs involved in coordinating graphene projects with industry.

The Natural Sciences and Engineering Research Council of Canada [NSERC] has placed graphene as one of five research topics in its target area of “Advanced Manufacturing” for Strategic Partnership Grants.

The UK government highlights advanced materials as one of its Eight Great Technologies, within which graphene is a major part of, having received investment for the NGI and GEIC buildings, along with EPSRC and Innovate UK projects. I wrote previously about the UK punching above its weight in terms of research, ( http://fullerex.com/index.php/articles/130-the-uk-needs-an-industrial-revolution-can-graphene-deliver/ ) but that R&D spending relative to GDP was too low compared to other developed nations. It is good to see that investment into graphene production in the UK is bucking that trend, and we should anticipate this will provide a positive economic outcome.

Yes, I’m  particularly interested in the fact Canada becomes more important as a producer when the numbers are relative but it is interesting to compare the chart with Eldridge’s text and to note how importance shifts depending on what numbers are being considered.

I recommend reading Eldridge’s piece in its entirety.

A few notes about graphene in Canada

By the way, the information in Eldridge’s essay about NSERC’s placement of graphene as a target area for grants is news to me. (As I have often noted here, I get more information about the Canadian nano scene from international sources than I do from our national sources.)

Happily I do get some home news such as a Jan. 5, 2017 email update from Lomiko Metals, a Canadian junior exploration company focused on graphite and lithium. The email provides the latest information from the company (as I’m not an expert in business or mining this is not an endorsement),

On December 13, 2016 we were excited to announce the completion of our drill program at the La Loutre flake graphite property. We received very positive results from our 1550 meter drilling program in 2015 in the area we are drilling now. In that release I stated, “”The intercepts of multiple zones of mineralization in the Refractory Zone where we have reported high grade intercepts previously is a very promising sign. The samples have been rushed to the ALS Laboratory for full assay testing,” We hope to have the results of those assays shortly.

December 16, 2016 Lomiko announced a 10:1 roll back of our shares. We believe that this roll back is important as we work towards securing long term equity financing for the company. Lomiko began trading on the basis of the roll back on December 19.

We believe that Graphite has a bright future because of the many new products that will rely on the material. I have attached a link to a video on Lomiko, Graphite and Graphene.  

https://youtu.be/Y–Y_Ub6oC4

January 3, 2017 Lomiko announced the extension and modification of its option agreements with Canadian Strategic Metals Inc. for the La Loutre and Lac des Iles properties. The effect of this extension is to give Lomiko additional time to complete the required work under the agreements.

Going forward Lomiko is in a much stronger position as the result of our share roll back. Potential equity funders who are very interested in our forthcoming assay results from La Loutre and the overall prospects of the company, have been reassured by our share consolidation.

Looking forward to 2017, we anticipate the assays of the La Loutre drilling to be delivered in the next 90 days, sooner we hope. We also anticipate additional equity funding will become available for the further exploration and delineation of the La Loutre and Lac des Iles properties and deposits.

More generally, we are confident that the market for large flake graphite will become firmer in 2017. Lomiko’s strategy of identifying near surface, ready to mine, graphite nodes puts us in the position to take advantage of improvements in the graphite price without having to commit large sums to massive mine development. As we identify and analyze the graphite nodes we are finding we increase the potential resources of the company. 2017 should see significantly improved resource estimates for Lomiko’s properties.

As I wasn’t familiar with the term ‘roll back of shares’, I looked it up and found this in an April 18, 2012 posting by Dudley Pierce Baker on kitco.com,

As a general rule, we hate to see an announcement of a share rollback, however, there exceptions which we cover below. Investors should always be aware that if a company has, say over 150 million shares outstanding, in our opinion, it is a potential candidate for a rollback and the announcement should not come as a surprise.

Weak markets, a low share price, a large number of shares outstanding, little or no cash and you have a company which is an idea candidate for a rollback.

The basic concept of a rollback or consolidation in a company’s shares is rather simple.

We are witnessing a few cases of rollbacks not with the purpose of raising more money but rather to facilitate the listing of the company’s shares on the NYSE [New York Stock Exchange] Amex.

I have no idea what situation Lomiko finds itself in but it should be noted that graphere research has been active since 2004 when the first graphene sheets were extracted from graphite. This is a relatively new field of endeavour and Lomiko (along with other companies) is in the position of pioneering the effort here in Canada. That said, there are many competitors to graphene and major international race to commercialize nanotechnology-enabled products.

Are there any leaders in the ‘graphene race?

Getting back to the question in the headline, I don’t think there are any leaders at the moment. No one seems to have what they used to call “a killer app,” that one application/product that everyone wants and which drive demand for graphene.

Revolutionary ‘smart’ windows from the UK

This is the first time I’ve seen self-cleaning and temperature control features mentioned together with regard to a ‘smart’ window, which makes this very exciting news. From a Jan. 20, 2016 UK Engineering and Physical Sciences Research Council (EPSRC) press release (also on EurekAlert),

A revolutionary new type of smart window could cut window-cleaning costs in tall buildings while reducing heating bills and boosting worker productivity. Developed by University College London (UCL) with support from EPSRC, prototype samples confirm that the glass can deliver three key benefits:

Self-cleaning: The window is ultra-resistant to water, so rain hitting the outside forms spherical droplets that roll easily over the surface – picking up dirt, dust and other contaminants and carrying them away. This is due to the pencil-like, conical design of nanostructures engraved onto the glass, trapping air and ensuring only a tiny amount of water comes into contact with the surface. This is different from normal glass, where raindrops cling to the surface, slide down more slowly and leave marks behind.
Energy-saving: The glass is coated with a very thin (5-10nm) film of vanadium dioxide which during cold periods stops thermal radiation escaping and so prevents heat loss; during hot periods it prevents infrared radiation from the sun entering the building. Vanadium dioxide is a cheap and abundant material, combining with the thinness of the coating to offer real cost and sustainability advantages over silver/gold-based and other coatings used by current energy-saving windows.
Anti-glare: The design of the nanostructures also gives the windows the same anti-reflective properties found in the eyes of moths and other creatures that have evolved to hide from predators. It cuts the amount of light reflected internally in a room to less than 5 per cent – compared with the 20-30 per cent achieved by other prototype vanadium dioxide coated, energy-saving windows – with this reduction in ‘glare’ providing a big boost to occupant comfort.

This is the first time that a nanostructure has been combined with a thermochromic coating. The bio-inspired nanostructure amplifies the thermochromics properties of the coating and the net result is a self-cleaning, highly performing smart window, said Dr Ioannis Papakonstantinou of UCL.

The UCL team calculate that the windows could result in a reduction in heating bills of up to 40 per cent, with the precise amount in any particular case depending on the exact latitude of the building where they are incorporated. Windows made of the ground-breaking glass could be especially well-suited to use in high-rise office buildings.

Dr Ioannis Papakonstantinou of UCL, project leader, explains: It’s currently estimated that, because of the obvious difficulties involved, the cost of cleaning a skyscraper’s windows in its first 5 years is the same as the original cost of installing them. Our glass could drastically cut this expenditure, quite apart from the appeal of lower energy bills and improved occupant productivity thanks to less glare. As the trend in architecture continues towards the inclusion of more glass, it’s vital that windows are as low-maintenance as possible.

So, when can I buy these windows? (from the press release; Note: Links have been removed)

Discussions are now under way with UK glass manufacturers with a view to driving this new window concept towards commercialisation. The key is to develop ways of scaling up the nano-manufacturing methods that the UCL team have specially developed to produce the glass, as well as scaling up the vanadium dioxide coating process. Smart windows could begin to reach the market within around 3-5 years [emphasis mine], depending on the team’s success in securing industrial interest.

Dr Papakonstantinou says: We also hope to develop a ‘smart’ film that incorporates our nanostructures and can easily be added to conventional domestic, office, factory and other windows on a DIY [do-it-yourself] basis to deliver the triple benefit of lower energy use, less light reflection and self-cleaning, without significantly affecting aesthetics.

Professor Philip Nelson, Chief Executive of EPSRC said: This project is an example of how investing in excellent research drives innovation to produce tangible benefits. In this case the new technique could deliver both energy savings and cost reductions.

A 5-year European Research Council (ERC) starting grant (IntelGlazing) has been awarded to fabricate smart windows on a large scale and test them under realistic, outdoor environmental conditions.

The UCL team that developed the prototype smart window includes Mr Alaric Taylor, a PhD student in Dr Papakonstantinou’s group, and Professor Ivan Parkin from UCL’s Department of Chemistry.

I wish them good luck.

One last note, these new windows are the outcome of a 2.5 year EPSRC funded project: Biologically Inspired Nanostructures for Smart Windows with Antireflection and Self-Cleaning Properties, which ended in Sept.  2015.

Synthetic Aesthetics: a book and an event (UK’s Victoria & Albert Museum) about synthetic biology and design

Sadly, I found out about the event after it took place (April 25, 2014) but I’m including it here as I think it serves a primer on putting together an imaginative art/science (art/sci) event, as well, synthetic biology is a topic I’ve covered here many times.

First, the book. Happily, it’s not too late to publicize it and, after all, that was at least one of the goals for the event. Here’s more about the book, from the UK’s Engineering and Physical Sciences Research Council April 25, 2014 news release (also on EurekAlert),

The emerging field of synthetic biology crosses the boundary between science and design, in order to design and manufacture biologically based parts, devices and systems that do not exist in the natural world, as well as the redesign of existing, natural biological systems.

This new technology has the potential to create new organisms for a variety of applications from materials to machines. What role can artists and designers play in our biological future?

This Friday [April 25, 2014], the Victoria & Albert Museum’s Friday Late turns the V&A into a living laboratory, bringing science and design together for one night of events, workshops and installations.

It will also feature the official launch of a new EPSRC-funded book ‘Synthetic Aesthetics: Investigating Synthetic Biology’s Designs on Nature’.

The book, by Alexandra Daisy Ginsberg, Jane Calvert, Pablo Schyfter, Alistair Elfick and Drew Endy, emerged from a research project ‘Sandpit: Synthetic aesthetics: connecting synthetic biology and creative design’ which was funded by the UK’s Engineering and Physical Sciences Research Council (EPSRC) and the National Science Foundation in the US.

Kedar Pandya, EPSRC’s Head of Engineering, said: “This event and the Synthetic Aesthetics book will act as a catalyst to spark informed debates and future research into how we develop and apply synthetic biology. Engineers and scientists are not divorced from the rest of society; ethical, moral and artistic questions need to be considered as we explore new science and technologies.”

The EPSRC project aimed to:

  • bring together scientists and engineers working in synthetic biology with artists and designers working in the creative industries, to develop long-lasting relationships which could help to improve their work
  • ensure aesthetic concerns and questions are reflected in the lifecycle of research projects and implementation of products, and enable inclusive and responsive technology development
  • produce new social scientific research that analyses and reflects on these interactions
  • initiate a new and expanded curriculum across both engineering and design disciplines to lead to new forms of engineering and new schools of art
  • improve synthetic biological projects, products and thus the world
  • engage and enable the full diversity of civilization’s creative resources to work with the synthetic biology community as full partners in creating and stewarding a beautifully integrated natural and engineered living world

Weirdly, the news release offered no link to the book.  Here’s the Synthetic Aesthetics: Investigating Synthetic Biology’s Designs on Nature page on the MIT Press website,

In this book, synthetic biologists, artists, designers, and social scientists investigate synthetic biology and design. After chapters that introduce the science and set the terms of the discussion, the book follows six boundary-crossing collaborations between artists and designers and synthetic biologists from around the world, helping us understand what it might mean to ‘design nature.’ These collaborations have resulted in biological computers that calculate form; speculative packaging that builds its own contents; algae that feeds on circuit boards; and a sampling of human cheeses. They raise intriguing questions about the scientific process, the delegation of creativity, our relationship to designed matter, and, the importance of critical engagement. Should these projects be considered art, design, synthetic biology, or something else altogether?

Synthetic biology is driven by its potential; some of these projects are fictions, beyond the current capabilities of the technology. Yet even as fictions, they help illuminate, question, and even shape the future of the field.

Now for the event description from the Victoria and Albert Museum’s Friday Late series, the April 25,2014  event Synthetic Aesthetics webpage,

Synthetic Aesthetics

Friday 25 April, 18.30-22.00

Can we design life itself? The emerging field of synthetic biology crosses the boundary between science and design to manipulate the stuff of life. These new designers use life as a programmable material, creating new organisms with radical applications from materials to machines. Friday Late turns the V&A into a living laboratory, bringing science and design together for one night of events, workshops and installations, each exploring our biological future.

The evening will feature the book launch of Synthetic Aesthetics: Investigating Synthetic Biology’s Designs on Nature (MIT Press). The book marks an important point in the development of the emerging discipline of synthetic biology, sitting at the intersection between design and science. The book is a result of research funded by the UK’s Engineering and Physical Sciences Research Council and the National Science Foundation in the US.

All events are free and places are designated on a first come, first served basis, unless stated otherwise. Filming and photography will be taking place at this event.

Please note, if the Museum reaches capacity we will allow access on a one-in-one-out basis.

Having observed how very deeply concerned scientists still are over the GMO (genetically modified organisms, sometimes also called ‘Frankenfoods’) panic that occurred in the early 2000s (I think), I suspect that efforts like this are meant (at least in part) to allay fears. In any event, the powers-that-be have taken a very engaging approach to their synthetic biology efforts. As for whether or not the event lived up to expectations, I have not been able to find any reviews or commentaries about it.

Competition for funds (feasibility studies about accelerating commercial applications of graphene in the UK)

The UK’s Technology Strategy Board and the Engineering and Physical Sciences Research Council (EPSRC) have given notice of their funding competition for feasibility studies on commercialising graphene  (registration opens April 7, 2014) according to a Feb. 11, 2014 news item on Nanowerk,

The Technology Strategy Board and the Engineering and Physical Sciences Research Council (EPSRC) are investing up to £2.5m in feasibility studies to accelerate commercial applications in the novel material, graphene. It will include related carbon-based, two-dimensional nanotechnologies that have recently emerged from the science base.

This competition will invest in projects that explore the realistic potential of graphene to yield new products that could disrupt markets. We expect them to stimulate development of a robust and competitive supply base to support the nascent graphene-using industry.

Proposals must be collaborative and business-led. We are looking to attract consortia drawn from small and medium- sized enterprises (SMEs) and/or large companies.

Universities and other research organisations can be partners in consortia where their high-end academic knowledge and innovation expertise is needed to deliver the project.

The Technology Strategy Board’s competition (Realising the graphene revolution) webpage contains more information such as this,

We expect to fund feasibility studies (mainly pre-industrial research projects) in which a business partner will generally attract up to 65% public funding for their project costs (75% for SMEs). Research organisations can attract funding of up to 100% of their costs.

We expect projects to last up to 12 months and to range in size up to total costs of £200k.

This competition opens on 7 April 2014 and the deadline for receipt of applications is noon on 4 June 2014. A briefing for potential applicants will be held on 24 April 2014. Consortium building events will be run by the Graphene Special Interest Group between 27 February 2014 and 18 March 2014. We strongly advise potential applicants to attend at least one of these events.

There is a deadline for registration (May 28, 2014 noon UK time) and you must register before submitting your proposal.

The Technology Strategy Board offers a competition brief (PDF) and more details on its Realising the graphene revolution webpage.

Controlling crystal growth for plastic electronics

A July 4, 2013 news item on Nanowerk highlights research into plastic electronics taking place at Imperial College London (ICL), Note: A link has been removed,

Scientists have discovered a way to better exploit a process that could revolutionise the way that electronic products are made.

The scientists from Imperial College London say improving the industrial process, which is called crystallisation, could revolutionise the way we produce electronic products, leading to advances across a whole range of fields; including reducing the cost and improving the design of plastic solar cells.

The process of making many well-known products from plastics involves controlling the way that microscopic crystals are formed within the material. By controlling the way that these crystals are grown engineers can determine the properties they want such as transparency and toughness. Controlling the growth of these crystals involves engineers adding small amounts of chemical additives to plastic formulations. This approach is used in making food boxes and other transparent plastic containers, but up until now it has not been used in the electronics industry.

The team from Imperial have now demonstrated that these additives can also be used to improve how an advanced type of flexible circuitry called plastic electronics is made.

The team found that when the additives were included in the formulation of plastic electronic circuitry they could be printed more reliably and over larger areas, which would reduce fabrication costs in the industry.

The team reported their findings this month in the journal Nature Materials (“Microstructure formation in molecular and polymer semiconductors assisted by nucleation agents”).

The June 7, 2013 Imperial College London news release by Joshua Howgego, which originated the news item, describes the researchers and the process in more detail,

Dr Natalie Stingelin, the leader of the study from the Department of Materials and Centre of Plastic Electronics at Imperial, says:

“Essentially, we have demonstrated a simple way to gain control over how crystals grow in electrically conducting ‘plastic’ semiconductors. Not only will this help industry fabricate plastic electronic devices like solar cells and sensors more efficiently. I believe it will also help scientists experimenting in other areas, such as protein crystallisation, an important part of the drug development process.”

Dr Stingelin and research associate Neil Treat looked at two additives, sold under the names IrgaclearÒ XT 386 and MilladÒ 3988, which are commonly used in industry. These chemicals are, for example, some of the ingredients used to improve the transparency of plastic drinking bottles. The researchers experimented with adding tiny amounts of these chemicals to the formulas of several different electrically conducting plastics, which are used in technologies such as security key cards, solar cells and displays.

The researchers found the additives gave them precise control over where crystals would form, meaning they could also control which parts of the printed material would conduct electricity. In addition, the crystallisations happened faster than normal. Usually plastic electronics are exposed to high temperatures to speed up the crystallisation process, but this can degrade the materials. This heat treatment treatment is no longer necessary if the additives are used.

Another industrially important advantage of using small amounts of the additives was that the crystallisation process happened more uniformly throughout the plastics, giving a consistent distribution of crystals.  The team say this could enable circuits in plastic electronics to be produced quickly and easily with roll-to-roll printing procedures similar to those used in the newspaper industry. This has been very challenging to achieve previously.

Dr Treat says: “Our work clearly shows that these additives are really good at controlling how materials crystallise. We have shown that printed electronics can be fabricated more reliably using this strategy. But what’s particularly exciting about all this is that the additives showed fantastic performance in many different types of conducting plastics. So I’m excited about the possibilities that this strategy could have in a wide range of materials.”

Dr Stingelin and Dr Treat collaborated with scientists from the University of California Santa Barbara (UCSB), and the National Renewable Energy Laboratory in Golden, US, and the Swiss Federal Institute of Technology on this study. The team are planning to continue working together to see if subtle chemical changes to the additives improve their effects – and design new additives.

There are some big plans for this discovery, from the news release,

They [the multinational team from ICL, UCSB, National Renewable Energy Laboratory, and Swiss Federal Institute of Technology]  will be working with the new Engineering and Physical Sciences Research Council (EPSRC)-funded Centre for Innovative Manufacturing in Large Area Electronics in order to drive the industrial exploitation of their process. The £5.6 million of funding for this centre, to be led by researchers from Cambridge University, was announced earlier this year [2013]. They are also exploring collaborations with printing companies with a view to further developing their circuit printing technique.

Latest on UK and graphene

The Brits are at it again with another graphene funding announcement, from the Dec. 28, 2012 news item on Azonano,

The Chancellor of the Exchequer, George Osborne MP, today announced £21.5 million of capital investment to commercialise graphene, one of the thinnest, lightest, strongest and most conductive materials to have been discovered, marked by the 2010 Nobel Prize in Physics as one of the world’s most ground breaking scientific achievements.

Three research projects at Imperial will share the Engineering and Physical Sciences Research Council (EPSRC) funding as part of a new programme with a number of industrial partners, including aeroplane manufacturer Airbus. The scientists receiving the grant hope to develop graphene technologies that will contribute to the UK economy and can be applied by industries around the world.

The Imperial College of London Dec. 27, 2012 news release, which originated the item, describes how the college’s £4.5M award will be used for three of its graphene projects,

In one project worth £1.35 million, led by Professor Tony Kinloch from the Department of Mechanical Engineering with colleagues from the Departments of Chemistry and Chemical Engineering, researchers will explore how combining graphene with current materials can improve the properties of aeroplane parts, such as making them resistant to lightning-strikes. They hope the same technology can also be used to develop coatings for wind-turbine blades, to make them scratch resistant and physically tougher in extreme weather conditions.

Professor Eduardo Saiz, from the Department of Materials, will develop new manufacturing processes using liquids that contain tiny suspended particles of graphene, in order to reduce the cost of currently expensive industrial techniques. This project will receive £1.91 million funding and involves scientists from Imperial’s Departments of Chemistry and Chemical Engineering, and Queen Mary, University of London.

£1.37 million of funding received by Professor Norbert Klein, also from the Department of Materials and shared with Imperial’s Department of Physics, will pay for new equipment to deposit extremely thin sheets of graphene, so scientists can explore its electrical properties. They hope that new medical scanning technology may be developed as a result of how graphene responds to high frequency electromagnetic waves, from microwave to terahertz frequencies and all the way to the wavelengths of visible light.

As noted on numerous occasions here  (most recently in an Oct. 11, 2012 posting), there is a competition for two prizes of 1 billion Euros each to be awarded to two European research projects in the European Union’s Future and Emerging Technologies Initiatives (FET). There are six flagship projects (whittled down from a larger number a few years ago) competing to be one of the two winners. There’s more about the FET Graphene Flagship project here. As you might expect, the Brits are heavily involved in the graphene flagship project.

Phyto-mining and environmental remediation flower in the United Kingdom

Researchers on a £3 million research programme called “Cleaning Land for Wealth” (CL4W) are confident they’ll be able to use flowers and plants to clean soil of poisonous materials (environmental remediation) and to recover platinum (phyto-mining). From the Nov. 21, 2012 news item on Nanowerk,

A consortium of researchers led by WMG (Warwick Manufacturing Group) at the University of Warwick are to embark on a £3 million research programme called “Cleaning Land for Wealth” (CL4W), that will use a common class of flower to restore poisoned soils while at the same time producing perfectly sized and shaped nano sized platinum and arsenic nanoparticles for use in catalytic convertors, cancer treatments and a range of other applications.

The Nov. 20, 2012 University of Warwick news release, which originated the news item, describes both how CL4W came together and how it produced an unintended project benefit,

A “Sandpit” exercise organised by the Engineering and Physical Sciences Research Council (EPSRC) allowed researchers from WMG (Warwick Manufacturing group) at the University of Warwick, Newcastle University, The University of Birmingham, Cranfield University and the University of Edinburgh to come together and share technologies and skills to come up with an innovative multidisciplinary research project that could help solve major technological and environmental challenges.

The researchers pooled their knowledge of how to use plants and bacteria to soak up particular elements and chemicals and how to subsequently harvest, process and collect that material. They have devised an approach to demonstrate the feasibility in which they are confident that they can use common classes of flower and plants (such as Alyssum), to remove poisonous chemicals such as arsenic and platinum from polluted land and water courses potentially allowing that land to be reclaimed and reused.

That in itself would be a significant achievement, but as the sandpit progressed the researchers found that jointly they had the knowledge to achieve much more than just cleaning up the land.

As lead researcher on the project Professor Kerry Kirwan from WMG at the University of Warwick explained:

“The processes we are developing will not only remove poisons such as arsenic and platinum from contaminated land and water courses, we are also confident that we can develop suitable biology and biorefining processes (or biofactories as we are calling them) that can tailor the shapes and sizes of the metallic nanoparticles they will make. This would give manufacturers of catalytic convertors, developers of cancer treatments and other applicable technologies exactly the right shape, size and functionality they need without subsequent refinement. We are also expecting to recover other high value materials such as fine chemicals, pharmaceuticals, anti-oxidants etc. from the crops during the same biorefining process.”

I last mentioned phyto-mining in my Sept. 26, 2012 post with regard to an international project being led by researchers at the University of York (UK).  The biorefining processes (biofactories) mentioned by Kirwan takes the idea of recovering platinum, etc. one step beyond phyto-mining recovery.

Here’s a picture of the flower (Alyssum) mentioned in the news release,

Alyssum montanum photographed by myself in 1988, Unterfranken, Germany [http://en.wikipedia.org/wiki/Alyssum]

From the Wikipedia essay (Note: I have removed links],

Alyssum is a genus of about 100–170 species of flowering plants in the family Brassicaceae, native to Europe, Asia, and northern Africa, with the highest species diversity in the Mediterranean region. The genus comprises annual and perennial herbaceous plants or (rarely) small shrubs, growing to 10–100 cm tall, with oblong-oval leaves and yellow or white flowers (pink to purple in a few species).

University of Liverpool announces work on HIV/AIDS nanomedicines

Given that Vancouver (Canada) is a world centre for HIV/AIDS  research (courtesy of Dr. Julio Montaner‘s work), the Aug. 30, 2012 news item on Nanowerk  about nanomedicines being developed at the University of Liverpool, which are less toxic therapeutic alternatives to current HIV/AIDS medications, caught my eye. From the news item,

Scientists at the University of Liverpool are leading a £1.65 million project to produce and test the first nanomedicines for treating HIV/AIDS.

There aren’t many details about how they are going to produce these nanomedicines other than what’s in these paragraphs in the Aug. 30, 2012 University of Liverpool news release,

The research project, funded by the [UK] Engineering and Physical Sciences Research Council (EPSRC), aims to produce cheaper, more effective medicines which have fewer side effects and are easier to give to newborns and children.

The new therapy options were generated by modifying existing HIV treatments, called antiretrovirals (ARVs). The University has recently produced ARV drug particles at the nanoscale which potentially reduce the toxicity and variability in the response different patients have to therapies. Drug nanoparticles have been shown to allow smaller doses in other disease areas which opens up possibilities to reduce drug side-effects and the risk of drug resistance. Nanoscale objects are less than one micron in size – a human hair is approximately 80 microns in diameter.

If I read the news release for this project rightly, there aren’t any immediate plans for making these nanomedicines widely available for treatment (from the University of Liverpool news release),

The project aims to deliver highly valuable data within three years and provide a platform for continual development and testing during that time

Elsewhere in the news release they do mention clinical trials,

Professor Andrew Owen, from the University’s Department of Molecular and Clinical Pharmacology, added: “We have integrated an assessment of pharmacology and safety early in the research and this has allowed us to rapidly progress lead options for clinical trials. The work has been conducted with the Medical Research Council (MRC) Centre for Drug Safety Science also based at the University.”

“Our data so far looks really exciting, offering the potential to reduce the doses required to control the HIV virus.  This work builds on initiatives by Médecins Sans Frontières and other groups to seek ways to improve ARV therapy and could have real benefits for the safety of ARVs globally. Importantly we also hope to reduce the costs of therapy for resource-limited countries where the burden of disease is highest.”

Interestingly, the other mention of taking this medicine into the field is in a  photo caption for the research team’s other featured member,

Professor Steve Rannard: “This project is the first step towards taking nanomedicine options out of our labs and into the clinic”

Good luck to them all!
