Catalytic Clothing debuts its kilts at Edinburgh International Science Festival

If it’s been your dream to catch a glimpse of hairy male legs in kilts designed (the kilts not the legs) to clean the air free of pollution, you can make it come true at the Edinburgh International Science Festival, March 30 – April 15, 2012.

Eileen Marable’s Feb. 22, 2012 article on DVICE provides details,

The unlikely pairing of a chemist and a fashion designer has led to the creation of air-purifying textiles. The duo will debut a catalyzed denim kilt at the Edinburgh International Science Festival at the end of March.

And by debut, they mean wearing it.

I wrote about Catalytic Clothing, a collaboration between Professor Helen Storey at the London College of Fashion and Professor Tony Ryan, a scientist at the University of Sheffield, in my July 8, 2011 posting. The story was about a nanotechnology-enabled couture dress that Storey had designed from a textile treated by Tony Ryan to remove pollution from the air. Marable’s story provides more technical detail about how this is accomplished. The kilts, by the way, will be cleaning the pollutant, nitric oxide from the air.

The Edinburgh International Science Festival website can be found here. At least one event is already sold out.

European and Asian science get cozy

The Euroscience Open Forum (ESOF) meeting scheduled July 11 – 15, 2012 in Dublin, Ireland features a session on titled ASEAN (Association of Southeast Asian Nations) – EU (European Union) Partnership Symposium: A Year of Science. Few details are available in the programme but I have found more information in a Feb. 23, 2012 news item on Nanowerk about Thailand’s NANOTEC,

NANOTEC researchers participated as speakers during the visit of science journalist from 8 European nations. The visit is organized under the umbrella of the FP7 funded SEA-EU-NET project, in which NSTDA [Thailand’s National Science and Technology Development Agency]  is a partner, and the ASEAN-EU Year of Science, Technology and Innovation 2012.

I guess it makes a certain kind of sense that I found out more about ASEAN in a news item originating from Thailand as it turns out that ASEAN was founded in Thailand in 1967. Meanwhile, the SEA-EU-NET website provides some insight into this ‘alphabet soup’ of international scientific cooperation (from the home page),

We are deepening S&T [science and technology] cooperation between Europe and Southeast Asia in a strategic manner by identifying opportunities for S&T cooperation, creating a policy dialogue between the countries of Europe and Southeast Asia on S&T cooperation, and increasing the participation of researchers from Southeast Asia in the EC’s Seventh Framework programme (FP7). FP7 is the European Commission’s €53 billion programme for funding research and is open to Southeast Asia partners across research institutions, universities, and industry (including SMEs).

Here’s a bit more about the Association of Southeast Asian Nations’ and European Union’s Science and Technology Year 2012,

The EU-ASEAN Year of STI 2012 is a SEA-EU-NET activity which was launched in November 2011 and will be carried out during 2012. Offering a plattform for the bi-regional STI dialogue, this activity coordinates a wide variety of joint scientific and technological events.

I hope I can get to Dublin to hear more about this ASEAN – EU effort.

Modestly viral science communication inspires

Students in the science communication masters programme at the Imperial College of London have created a video (Science Nation Army) that has gone modestly viral. From the Feb. 23, 2012 posting by Anna Perman on the Guardian Science blogs,

This week, a video made by myself and three friends from the science communications masters course at Imperial College went viral. Not “Fenton the dog” viral, but trending on YouTube (316,000 hits and counting), a spot on CBS News blog, in the Sun newspaper and a teeny-tiny snippet in the Guardian’s own G2 (too tiny even for a link). The video shows us recreating Seven Nation Army by the White Stripes, using as our instruments the tools lying around in a lab at Imperial, and some “creative” editing techniques.

We did this to communicate science. And it seems to have worked.

Here’s the video,

It is part of a larger project, a multimedia blog developed by these students, Inside Knowledge: The Student Blog for the Public Library of Science (PLoS) blog network. More from Perman about the project,

A year ago, the four of us [Anna Perman, Ben Good, Lizzie Crouch, and David Robertson] started working with the research group at Imperial’s Blast lab (now part of the Royal British Legion Centre for Blast Injury Studies) to make a multimedia blog for the PLoS blog network about their work. It wasn’t an easy journey. The lab includes military personnel, has links to the ministry of defence and works with human tissue, so getting permission to film and write about their research was no mean feat.

In our film we tried to convey the entire experience of science, from the tedium of sitting with a lab book, to the excitement of their explosive experiments.

We also wanted to get people to think about the lab environment not as somewhere scary and alien, but somewhere accessible, and most importantly, somewhere fun to work.

This particular video was to show the variety of people who must work harmoniously to conduct a piece of scientific research. Just like a band in which a group with different talents create something more than the sum of its parts, a research group like Blast contains a diversity of doctors, mechanical engineers and biophysicists.

There are two groups working on The Student Blog, the group from the UK’s Imperial College of London (Inside Knowledge) and a second group from Stanford University in the US called Science, Upstream (Jamie Hansen and Julia James). I find the project a little confusing as I don’t see any postings after Sept. 2011 for Inside Knowledge and Science, Upstream, which seems to have a separate space on the PLoS website, doesn’t feature any postings after April 2011.

Still, I like the idea of the video and of communicating science in as many ways and in as many venues as possible. Oh, and I really enjoyed the Science Nation Army.

This is a good nanocellulose video? Really!?!

Perhaps I’ve lost my grip but this video seems a little lacking and, frankly, very 1950s/60s in spirit, if not in look when they would have used much brighter colours. I’m talking about the TAPPI ((Technical Association of the Pulp and Paper Industry) video mentioned in a Feb. 23, 2012 news item on Nanowerk,

A new video on potential applications for nanotechnology in the forest products industry has been widely adopted as a teaching and learning tool. [emphasis mine] Dozens of organizations have added it to their website and the video website has been visited 1037 times in the past three months. The video clearly and concisely covers current uses of tree fiber and the tremendous potential of nanotechnology for development of new products.

What would you be teaching and/or learning from this video? For anyone who’s curious, here it is,

Based on the information in this video and assuming the individual had no prior knowledge of nanocellulose , could the average person describe or discuss it after watching this video? At the best, someone might be able to say there’s something really small in a tree called nanocellulose and it can be used for all kinds of things, like cars and food.  Is this really TAPPI’s and its partners’ concept of a “learning and teaching tool?” It looks more like a public relations ‘fluff’ piece to me.

(The Rethinktrees.org website listed at the end of the video does not yet seem to be functional and you will be rerouted to a TAPPI page. So for anyone who wants to see the video in its ‘native habitat’, you can go here.)

Apparently, I am alone in my jaundiced view of this video production. From the news item,

“Congratulations on an outstanding video presentation! The Rethink trees video presents a high quality message of the new directions our industry is taking into innovative fields such as nanotechnology,” states Richard Berry, VP and Chief Technology Officer, CelluForce Inc. “We are very proud to be part of this adventure.”

“The TAPPI Nanotechnology video does a superb job of telling the story of how forests can be managed responsibly to make sustainable products. Not only paper, but new generations of innovative materials as well like liquid biodiesel and nanocellulose that can be used in a multitude of applications. Imagine filling your car with biodiesel made from wood – this will be a reality in the near future. Forests are not only renewable, they have a multitude of other environmental benefits that are essential to our planet and, as the TAPPI video states, they hold the secrets to many future sustainable products,” according to Phil Riebel, President,Two Sides U.S.

There is an interesting point made by Michael Crumpacker (love that last name) about why we might want to include farmed trees in our notion of environmental sustainability (from the news item),

“In our society we love being politically correct and jumping on the band wagon to spread information even if it’s incorrect. A perfect example is the statement: “Please consider the environment before printing this email.” The truth is that if you did consider the environment you would print the email because trees are renewable, recyclable and sustainable and pulp is a cash crop that is grown by farmers and healthy for the environment. For every tree harvested in the United States four are planted. If we keep eliminating the need for paper, fewer companies will be willing or able to afford to manage our forests, ” notes Michael Crumpacker, President, TCC Printing & Imaging. [emphasis mine]

I think he means tree farms as it would be ridiculous to say that forests need to be managed by companies. After all, forests have grown and developed for centuries without any need for management from forest companies.

It’s good to start the day with a laugh. I hope you enjoyed the video as much as I did.

London School of Economics offers a guide to Twitter for researchers

More specifically the guide is being offered by the London School of Economics (LSE) Public Policy Group and it’s called, Using Twitter in university research, teaching and impact activities (pdf). From the Feb. 22, 2012 news item on Nanowerk,

Thousands of academics and researchers at all levels of experience and across all disciplines already use Twitter daily, alongside more than 200 million other users.

Yet how can such a brief medium have any relevance to universities and academia, where journal articles are 3,000 to 8,000 words long, and where books contain 80,000 words? Can anything of academic value ever be said in just 140 characters?

This guide answers these questions, showing you how to get started on Twitter and showing you how Twitter can be used as a resource for research, teaching and impact activities.

Here’s a sample of some of the advice offered in the 12 pp. guide,

A Twitter operation can add extra value to almost any research project in several ways.

Tweet about each new publication, website update or new blog that the project completes. To gauge feedback, you could send a tweet that links to your research blog and ask your followers for their feedback and comments.

For tweeting to work well, always make sure that an open-web full version or summary of every publication, conference presentation or talk at an event is available online. Summarize every article published in closed-web journal on a blog, or lodge an extended summary on your university’s online research depository. In addition, sites like www.scribd.com are useful for depositing open web versions.

Tweet about new developments of interest from the project’s point of view, for instance, relevant government policy changes, think tank reports, or journal articles.

Use hashtags (#) to make your materials more visible – e.g. #phdchat. Don’t be afraid to start your own.

Use your tweets to cover developments at other related research sites, retweeting interesting new material that they produce. This may appear to some as ‘helping the competition’, but in most research areas the key problem is to get more attention for the area as a whole. Building up a Twitter network of reciprocating research projects can help everyone to keep up to date more easily, improve the standard and pace of debate, and so attract more attention (and funding) into the research area.

Twitter provides many opportunities for ‘crowd sourcing’ research activities across the sciences, social sciences, history and literature – by getting people to help with gathering information, making observations, undertaking data analysis, transcribing and editing documents – all done just for the love of it. Some researchers have also used Twitter to help ‘crowdsource’ research funding from interested public bodies. You can read more about crowdsourcing at the LSE Impact blog. (p. 8)

For anyone who doesn’t already have an account, it’s pretty easy to set one up at Twitter.com. Once you’re set up, you can follow Nanowerk by going here: http://twitter.com/nanowerk and/or you can follow me at http://twitter.com/frogheart.

‘Feeling’ the power; thermoelectric device converts body heat to electricity

From time to time I read about these harvesting technologies designed to take advantage of the fact that human beings produce electricity which could be used to power devices such as mobile (cell) phones. I love the idea but I’ve been waiting over four years now for something to get to market.  It appears my wait is going to continue despite this encouraging Feb. 22, 2012 news item on physorg.com,

Never get stranded with a dead cell phone again. A promising new technology called Power Felt, a thermoelectric device that converts body heat into an electrical current, soon could create enough juice to make another call simply by touching it.

Developed by researchers in the Center for Nanotechnology and Molecular Materials at Wake Forest University [located in North Carolina], Power Felt is comprised of tiny carbon nanotubes locked up in flexible plastic fibers and made to feel like fabric. The technology uses temperature differences – room temperature versus body temperature, for instance – to create a charge.

Cost has prevented thermoelectrics from being used more widely in consumer products. Standard thermoelectric devices use a much more efficient compound called bismuth telluride to turn heat into power in products including mobile refrigerators and CPU coolers, but researchers say it can cost $1,000 per kilogram. Like silicon, they liken Power Felt’s affordability to demand in volume and think someday it could cost only $1 to add to a cell phone cover.

Currently, 72 stacked layers in the fabric yield about 140 nanowatts of power. The team is evaluating several ways to add more nanotube layers and make them even thinner to boost the power output.

Although there’s more work to do before Power Felt is ready for market, Hewitt [Corey Hewitt] says, “I imagine being able to make a jacket with a completely thermoelectric inside liner that gathers warmth from body heat, while the exterior remains cold from the outside temperature. If the Power Felt is efficient enough, you could potentially power an iPod, which would be great for distance runners. It’s definitely within reach.”

Wake Forest is in talks with investors to produce Power Felt commercially.

This work is being done under the auspices of David Carroll, director of Wake University’s Center for Nanotechnology and Molecular Materials.  I did find information about the industrial partners involved in the research, from the Carroll Research Group webpage,

The “Power Fabrics” project has several industrial partners:

FiberCell Inc. Winston-Salem NC
NanotechLabs Inc. Yadkinville NC
Sineurop Inc. Stuttgart Germany

I find the mention of industrial partners and investors promising.

Science images too busy/ugly? Call the University of Washington’s Design Help Desk

After several days at the AAAS (American Association for the Advancement of Science) 2012 annual meeting, I can definitely support the design help desk project at the University of Washington (UW). From the Feb. 22, 2012 news item by Hannah Hickey on physorg.com,

A group of University of Washington researchers has launched a unique experiment matching science students with those in design. The new Design Help Desk, similar to a writing help desk, offers scientists a chance to meet with someone who can help them create more effective figures, tables and graphs.

“In modern publications, up to half of the space can be taken up by figures,” said principal investigator Marco Rolandi, a UW assistant professor of materials science and engineering. His group studies materials at the nanometer scale, and much of the data is ultimately contained in microscope images.

“As a new faculty member, I was spending a lot of time teaching my students how to make figures for publications, even though I myself didn’t have any formal training,” Rolandi said.

It was a case of the blind leading the blind, he said. Rolandi sought out collaborators on campus, and eventually funding from the National Science Foundation, to create support that until now didn’t exist – and to study how well it works.

The research project (Design Help Desk) has two principal investigators, Rolandi and Karen Cheng, from Hickey’s Feb. 21, 2012 news release on the University of Washington website,

“We are becoming a more visual culture,” says Karen Cheng, a UW associate professor of design (who also completed a bachelor’s in chemical engineering). Still, most science visuals “could use significant improvement from a visual point of view,” she said. “It’s just not a field where design has been part of the training.”

This hasn’t always been the case. In Galileo’s time, scientists were also trained in art. These days, scientists often produce a graph using Microsoft Excel or PowerPoint’s default settings – which might look fine to them, but may have fundamental design problems. [emphasis mine]

Meanwhile, even journals are focusing on the importance of figures, often asking authors to improve them before publication.

“It’s not just about looking pretty. It’s about conveying complex information in a clear way,” Cheng said.

The point about science and art being more closely intertwined in the past was made Gunalan Nadarajan (Vice Provost at the Maryland Institute College of Art) at the AAAS 2012 annual meeting (my Feb. 20, 2012 posting). Nadarajan mentioned a new project being developed, Network for Science Engineering Art and Design. It’s so new they don’t yet have a website.

This is not being done in the wild. Scientists and designers are not set loose upon each other (from the UW news release),

Clients who arrive for a session at the Design Help Desk are first greeted by postdoctoral researcher Yeechi Chen, who earned her doctorate in physics at the UW and has completed a UW certificate course in natural science illustration. Chen can act as an intermediary between the scientist and the designer, and reassure new clients that scientists are involved in the project.

During the half-hour session, the scientist client and design consultant are alone in the room. The designer first asks the scientist about his or her goals – timeline, stage in the design process, publication venue, and main points to convey. The designers typically use pen and paper to sketch out their ideas.

The session is videotaped for use in the group’s study, if the client agrees. One camera records the face-to-face interaction, while a second camera on the ceiling records the sketching and hand movements.

Interestingly (to me anyway), the Design Help Desk appears on a UW webpage dedicated to Visual Communication in {Nano} Science. The page offers a very minimalist image, a description of the project and the team, and offers links to resources, e.g., A Brief Guide to Designing Effective Figures for the Scientific Paper ((behind a paywall)) which was published  in August 2011 in Advanced Materials.

Nanosurgery in Montréal (Canada)

When I was typing up charts for home nursing care (nurses visiting patients in their home after a hospital procedure), I routinely asked if a patient whose cancer had metastasized would require palliative care even though the answer would be yes. In over 3 years and after hundreds of charts, I only had one ‘No’. So it is with some interest I read about Michel Meunier and his team’s work at the Polytechnique Montréal (Québec, Canada). From the Feb. 16, 2012 news item on Nanowerk,

The unique method developed by Professor Michel Meunier and his team uses a femtosecond laser (a laser with ultra-short pulses) along with gold nanoparticles. Deposited on the cells, these nanoparticles concentrate the laser’s energy and make it possible to perform nanometric-scale surgery in an extremely precise and non-invasive fashion. The technique allows to change the expression of genes in the cancer cells and could be used to slow their migration and prevent the formation of metastases.

The technique perfected by Professor Meunier and his colleagues is a promising alternative to conventional cellular transfection methods, such as lipofection. The experiment, carried out in Montréal laboratories on malignant human melanoma cells, demonstrated 70% optoporation effectiveness, as well as a transfection performance three times higher than lipofection treatment. In addition, unlike conventional treatment, which destroys the physical integrity of the cells, the new method assures cellular viability, with a toxicity of less than 1%.

The Polytechnique’s Feb. 16, 2012 press release is here and you can find out more about Meunier and his lab here (in English and en français). For those eager to read the article, it was published in Biomaterials (vol. 33, no. 7, March 2012, pp. 2345-50) is titled, Off-resonance plasmonic enhanced femtosecond laser optoporation and transfection of cancer cells and is behind a paywall.

Canadian research (and other ‘excellence’) initiatives get some competition from the European Research Council

Canadians have been throwing money at scientists for some years now (my May 20, 2010 posting about the Canada Excellence Research Chairs programme). We’ve attempted to recruit from around the world with our ‘research chairs’ and our ‘excellence research chairs’ and our Network Centres of Excellence (NCE) all serving as enticements.

The European Research Council (ERC) has announced that they will be trying to beat us at our own game at the AAAS 2012 annual meeting in Vancouver (this new ERC programme was launched in Boston, Massachusetts in January 2012). From the Agence France Presse Feb. 20, 2012 news item on physorg.com,

The European Research Council launched an international campaign Sunday to court the world’s top scientists to work in Europe with grants of up to 3.5 million euro (4.6 million dollars) over five years.

The goal of the program is to boost the number of non-European researchers to over 500. Currently, just 100 of its 2,600 grant recipients are from outside Europe, said council secretary general Donald Dingwell.

Dingwell, who after Canada plans to visit South Africa, several Asian countries, Latin America, Russia and Ukraine, the United States and Mexico, said the main condition is that recipients spend half their time in Europe and be affiliated with a European institution.

ERC’s Dec. 2011 newsletter features an article, Going global; Making Europe a prime location for the best brains, where they outline the campaign which actually started in 2007 but this latest initiative (Destination Europe) offers a renewed and more aggressive approach (and similarities to the Canadian efforts) to attracting more scientists to Europe. From the article,

The ERC Secretary General Donald Dingwell has been given a key role in this venture. Originally from Canada and with ample international experience, he will be the ERC’s Ambassador worldwide … The US is undoubtedly a hotspot for talent and thus for the ERC, but also the BRICS countries (Brazil, Russia, India, China, and South Africa) and other top performers in science will be a priority in the years to come.

That’s a nice touch, having an expat Canadian lead your somewhat competitive initiative.

British royalty and graphene

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

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

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

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

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

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