Chad Mirkin, spherical nucleic acids, and a new ‘periodic table’

There was a big splash in July 2012 with the announcement that Chad Mirkin’s team at Northwestern University (Chicago, Illinois) had devised a skin cream that penetrated the skin barrier to deliver medication (my July 4, 2012 posting),

A team led by a physician-scientist and a chemist — from the fields of dermatology and nanotechnology — is the first to demonstrate the use of commercial moisturizers to deliver gene regulation technology that has great potential for life-saving therapies for skin cancers.

The topical delivery of gene regulation technology to cells deep in the skin is extremely difficult because of the formidable defenses skin provides for the body. The Northwestern approach takes advantage of drugs consisting of novel spherical arrangements of nucleic acids. These structures, each about 1,000 times smaller than the diameter of a human hair, have the unique ability to recruit and bind to natural proteins that allow them to traverse the skin and enter cells.

Mirkin has just finished presenting (Feb. 15, 2013 and Feb. 17, 2013) more information about spherical nucleic acids and their implications at the AAAS  (American Association for the Advancement of Science) 2013 meeting in Boston, Massachusetts. From the Feb. 15, 2013 news release on EurekAlert,

Northwestern University’s Chad A. Mirkin, a world-renowned leader in nanotechnology research and its application, has invented and developed a powerful material that could revolutionize biomedicine: spherical nucleic acids (SNAs).

Potential applications include using SNAs to carry nucleic acid-based therapeutics to the brain for the treatment of glioblastoma, the most aggressive form of brain cancer, as well as other neurological disorders such as Alzheimer’s and Parkinson’s diseases. Mirkin is aggressively pursuing treatments for such diseases with Alexander H. Stegh, an assistant professor of neurology at Northwestern’s Feinberg School of Medicine.

“These structures are really quite spectacular and incredibly functional,” Mirkin said. “People don’t typically think about DNA in spherical form, but this novel arrangement of nucleic acids imparts interesting chemical and physical properties that are very different from conventional nucleic acids.”

Spherical nucleic acids consist of densely packed, highly oriented nucleic acids arranged on the surface of a nanoparticle, typically gold or silver.  [emphasis mine] The tiny non-toxic balls, each roughly 15 nanometers in diameter, can do things the familiar but more cumbersome double helix can’t do:

  • SNAs can naturally enter cells and effect gene knockdown, making SNAs a superior tool for treating genetic diseases using gene regulation technology.
  • SNAs can easily cross formidable barriers in the human body, including the blood-brain barrier and the layers that make up skin.
  • SNAs don’t elicit an immune response, and they resist degradation, resulting in longer lifetimes in the body.

“The field of medicine needs new constructs and strategies for treating disease,” Mirkin said. “Many of the ways we treat disease are based on old methods and materials. Nanotechnology offers the ability to rapidly create new structures with properties that are very different from conventional forms of matter.”

“We now can go after a whole new set of diseases,” Mirkin said. “Thanks to the Human Genome Project and all of the genomics research over the last two decades, we have an enormous number of known targets. And we can use the same tool for each, the spherical nucleic acid. We simply change the sequence to match the target gene. That’s the power of gene regulation technology.”

###

A member of President Obama’s Council of Advisors on Science and Technology, Mirkin is known for invention and development of biological and chemical diagnostic systems based upon nanomaterials. He is the inventor and chief developer of Dip-Pen Nanolithography, a groundbreaking nanoscale fabrication and analytical tool, and is the founder of four Chicago-based companies: AuraSense, AuraSense Therapeutics, Nanosphere and NanoInk.

Mirkin, in addition to his work with spherical nucleic acids, has been busy with other nanoparticles and possible dreams of a new ‘periodic table of elements’, from the Feb. 17, 2013 news release on EurekAlert,

Forging a new periodic table using nanostructures

Northwestern University’s Chad A. Mirkin, …, has developed a completely new set of building blocks that is based on nanoparticles and DNA. Using these tools, scientists will be able to build — from the bottom up, just as nature does — new and useful structures.

“We have a new set of building blocks,” Mirkin said. “Instead of taking what nature gives you, we can control every property of the new material we make. We’ve always had this vision of building matter and controlling architecture from the bottom up, and now we’ve shown it can be done.”

Using nanoparticles and DNA, Mirkin has built more than 200 different crystal structures with 17 different particle arrangements. Some of the lattice types can be found in nature, but he also has built new structures that have no naturally occurring mineral counterpart.

Mirkin can make new materials and arrangements of particles by controlling the size, shape, type and location of nanoparticles within a given particle lattice. He has developed a set of design rules that allow him to control almost every property of a material.

New materials developed using his method could help improve the efficiency of optics, electronics and energy storage technologies. “These same nanoparticle building blocks have already found wide-spread commercial utility in biology and medicine as diagnostic probes for markers of disease,” Mirkin added.

With this present advance, Mirkin uses nanoparticles as “atoms” and DNA as “bonds.” He starts with a nanoparticle, which could be gold, silver, platinum or a quantum dot, for example. The core material is selected depending on what physical properties the final structure should have.

He then attaches hundreds of strands of DNA (oligonucleotides) to the particle. The oligonucleotide’s DNA sequence and length determine how bonds form between nanoparticles and guide the formation of specific crystal lattices.

“This constitutes a completely new class of building blocks in materials science that gives you a type of programmability that is extraordinarily versatile and powerful,” Mirkin said. “It provides nanotechnologists for the first time the ability to tailor properties of materials in a highly programmable way from the bottom up.”

If I read these two news releases rightly, the process (nanoparticles as atoms and DNA as bonds), Mirkin uses to create new structures is the same process he has used to create spherical nucleic acids. Given Mirkin’s entrepreneurial inclinations, I am curious as to how many and what kind of patents might be ‘protecting’ this work.

AAAS 2013 meeting in Boston,US and Canadian research excellence

The 2013 annual meeting for the American Association for the Advancement of Science (AAAS) will be held in Boston, Massachusetts from Feb. 14 – 18, 2013 with a much better theme this year, The Beauty and Benefits of Science, than last year’s, Flattening the World. (It didn’t take much to improve the theme, eh?)

Plenary speakers range from AAAS’s president, William N. Press to Nathan Myhrvold, a venture capitalist to astrophysicist, Robert Kirshner to Cynthia Kenyon, a molecular biologist to Sherry Turkle. From the AAAS webpage describing Turkle’s 2013 plenary lecture,

Sherry Turkle

Abby Rockefeller Mauzé Professor of the Social Studies of Science and Technology in the Program in Science, Technology, and Society, MIT

The Robotic Moment: What Do We Forget When We Talk to Machines?

Dr. Turkle is founder and director of the MIT Initiative on Technology and Self. She received a joint doctorate in sociology and personality psychology from Harvard University and is a licensed clinical psychologist. Her research focuses on the psychology of human relationships with technology, especially in the realm of how people relate to computational objects. She is an expert on mobile technology, social networking, and sociable robotics and a regular media commentator on the social and psychological effects of technology. Her most recent book is Alone Together: Why We Expect More from Technology and Less from Each Other.

Given my experience last year in the 2012 meeting media room, I’m surprised to see a social media session is planned, from the session webpage,

Engaging with Social Media
Communicating Science
Thursday, February 14, 2013: 3:00 PM-4:30 PM
Ballroom A (Hynes Convention Center)

In a constantly changing online landscape, what is the best way for scientists and engineers to engage the public through social media? This session will discuss how people are accessing science information via blogs and social networks and the importance of researchers getting involved directly. [emphasis mine]  Speakers will address the ways that researchers can create meaningful interactions with the public through social media.

Organizer: Cornelia Dean, The New York Times
Co-Organizer: Dennis Meredith, Science Communication Consultant
Moderator: Carl Zimmer, Independent Science Journalist

Speakers:
XXXX Scicurious, Neurotic Physiology
Science Blogging for Fun and Profit
Christie Wilcox, University of Hawaii
Science in a Digital Age
Dominique Brossard, University of Wisconsin
Science and the Public in New Information Environments

I’d love to see how the theme of ‘researcher engaging directly’ gets developed. In theory, I have no problems with the concept. Unfortunately, those words are sometimes code for this perspective, ‘only experts (scientists/accredited journalists) should discuss or write about science’. A couple of quick comments, my Jan. 13, 2012 posting featured an interview with Carl Zimmer, this session’s moderator, about his science tattoo book and Dominique Brossard, one of the speakers, was last mentioned here in my Jan. 24, 2013 posting titled, Tweet your nano, in the context of a research study on social media and nanotechnology.

In keeping with the times (as per my Jan. 28, 2013 posting about the colossal research prizes for the Graphene and Human Brain Project initiatives), the 2012 AAAS annual meeting features a Brain Function and Plasticity thread or subtheme. There’s this session amongst others,

The Connectome: From the Synapse to Brain Networks in Health and Disease
Brain Function and Plasticity
Saturday, February 16, 2013: 8:30 AM-11:30 AM
Room 304 (Hynes Convention Center)

A series of innovative studies are being done to map the brain from the molecular to the systems level both structurally and functionally. At the synaptic level, how neurotransmitters, their receptors, and signaling pathways influence neural function and plasticity is becoming much better understood. Integrating neuronal function at the level of single neurons and groups of neurons into larger circuits at the anatomical level in the mammalian brain, while a daunting task, is being studied by advanced imaging techniques requiring vast amounts of information storage and processing. To integrate local circuit function with whole brain function, understanding the structure and processing of brain networks is critical. A major project to accomplish this task, the Human Connectome Project, is in the process of integrating the structure and function of brain networks using the most advanced imaging and analysis techniques in 1,200 people, including twins and their nontwin siblings. This step will allow for major new insights into not only brain structure and function, but also their genetic underpinnings. Comparing this information in both the normal brain and in different brain disorders such as neurodegenerative diseases is providing novel insights into how understanding brain function from the molecular to the systems level will provide insights into normal brain function and disease pathogenesis as well as provide new treatment strategies.

Organizer:

David Holtzman, Washington University

Speakers:

Mark F. Bear, Massachusetts Institute of Technology
Molecules and Mechanisms Involved in Synaptic Plasticity in Health and Disease
Jeff Lichtman, Harvard University

Then, there’s this session featuring graphene,

What’s Hot in Cold
Sunday, February 17, 2013: 8:30 AM-11:30 AM
Room 308 (Hynes Convention Center)

The study of ultracold atoms and molecules is now the frontier of low-temperature science, reaching temperatures of a few hundred picokelvin above absolute zero. This field was made possible by a technique that did not exist 30 years ago: laser cooling of atoms. It is hardly obvious that the laser, which produces the most intense light on Earth and is routinely used in industrial applications for cutting and welding medal, would also provide the most powerful coolant. Such are the surprises of science, where a breakthrough in one area transforms others in unexpected ways. Since 1997, eight Nobel Laureates in physics have been recognized for contributions to ultracold atomic and molecular science, which has become one of the most vibrant fields in physics, cutting across traditional disciplinary boundaries, e.g., atomic, molecular, and optical; condensed matter; statistical physics; and nuclear and particle physics. This field builds on two accomplishments that it was the first to achieve: first, the production of quantum degenerate matter using a wide range of elements and, second, exquisite control of quantum degenerate matter at the atomic level. These have led to record low temperatures, ultraprecise atomic clocks, and new forms of quantum matter that generalize ideas from magnetism superconductivity and graphene physics.

Organizer:

Charles W. Clark, Joint Quantum Institute

Speakers:

Markus Greiner, Harvard University
Quantum Simulation: A Microscopic View of Quantum Matter
Ana Maria Rey, University of Colorado
Atomic Clocks: From Precise Timekeepers to Quantum Simulators

Amongst all these other sessions, there’s a session about Canadian science,

Introduction to Canadian Research Excellence: Evidence & Examples
Friday, February 15, 2013: 11:00 AM-12:00 PM
Room 205 (Hynes Convention Center)

The Canada Pavilion in the Exhibit Hall gives a taste of what lies north of Boston and the 49th parallel. Join us at this workshop to learn about opportunities in Canada for research and study. Canada recently completed a comprehensive analysis of its domestic science and technology strengths. The final report of the expert panel of the Council of Canadian Academies will be presented, including the use of global benchmarks and insights on international collaborations. Two of the drivers for Canadian excellence will be introduced: large-scale science facilities in key fields and a system of targeted fellowships and research chairs that recruit globally.

Coordinator:

Tim Meyer, TRIUMF

Presenters:

Tim Meyer, TRIUMF,
Chad Gaffield, Social Sciences and Humanities Research Council of Canada
Eliot Phillipson, University of Toronto

“Introduced,” really? Large scale science facilities are not new in Canada or anywhere else for that matter and the programmes of targeted fellowships have been around long enough and successful enough that it is being copied.

First, there was the Canada Research Chair programme, which was instituted in 2000. From the About Us page (Note: A link has been removed),

The Canada Research Chairs program stands at the centre of a national strategy to make Canada one of the world’s top countries in research and development. [emphasis mine]

In 2000, the Government of Canada created a permanent program to establish 2000 research professorships—Canada Research Chairs—in eligible degree-granting institutions across the country.

The Canada Research Chairs program invests $300 million per year to attract and retain some of the world’s most accomplished and promising minds.

This was programme was followed up with the Canada Excellence Research Chairs Program in 2008, from the Background page (Note: A link has been removed),

Launched in 2008, the Canada Excellence Research Chairs (CERC) Program supports Canadian universities in their efforts to build on Canada’s growing reputation as a global leader in research and innovation. The program awards world-renowned researchers and their teams up to $10 million over seven years to establish ambitious research programs at Canadian universities. These awards are among the most prestigious and generous available globally.

In May 2010, the first group of Canada Excellence Research Chairs was announced. Selected through a rigorous, multilevel peer review process, these chairholders are helping Canada build a critical mass of expertise in the four priority research areas of the federal government’s science and technology strategy …

Here’s an excerpt from my Feb. 21, 2012 posting,

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).

The Canadian report these folks will be discussing was released in Sept. 2012 and was  featured here in a two-part commentary,

The State of Science and Technology in Canada, 2012 report—examined (part 1: the executive summary)

The State of Science and Technology in Canada, 2012 report—examined (part 2: the rest of the report)

My Sept. 27, 2012 posting features my response to the report’s launch on that day.

As for the AAAS 2013 annual meeting, there’s a lot, lot more of it and it’s worth checking out, if for no other reason than to anticipate the types of science stories you will be seeing in the coming months.

Webinar on television and film productions collaborating with scientists

David Bruggeman in an Aug. 26, 2012 posting on his Pasco Phronesis blog features information about a webinar being co-hosted by the National Academies of Sciences (through their Science and Entertainment Exchange initiative) and the American Association for the Advancement of Science (AAAS),

The Science and Entertainment Exchange, a National Academies program to facilitate connections between entertainment productions and scientists and engineers that could serve as advisers for those productions.  On Wednesday [Aug. 29, 2102], the Exchange is holding a webinar to discuss recent productions and how various films and television programs are trying to maximize entertainment value and the accuracy of scientific and technical information.

Here’s a little more about the webinar from the AAAS event page,

Summer is synonymous with Hollywood blockbusters and the popular genre for these films (more often that not) is science fiction. “The Dark Knight Rises,” “Prometheus,” and “The Amazing Spider-Man” are just three of this summer’s box office heavyweights, each offering over the top special effects meant to wow audiences. But how much of what we are seeing is actually scientifically possible?

… Hollywood’s approach towards science, and scientists, has started to change.

In this hour-long webinar we’ll look at some TV and film collaborations that are bringing scientists and Hollywood professionals together in an effort to create programming that is both entertaining and more scientifically accurate.

Guest Speakers:

Kevin Grazier
Science Advisor/Researcher
NASA

Kevin Grazier is a writer/producer and also currently the science advisor on TNT’s “Falling Skies,” Syfy’s upcoming epic “Defiance,” and next summer’s blockbuster “Gravity.”  He formerly served as science advisor on “Eureka,” the Peabody-award-winning “Battlestar Galactica,” “The Event,” and several other series.  Grazier is a recovering rocket scientist, and spent 15 years on the Cassini/Huygens Mission to Saturn and Titan. Still an active researcher, his research areas are numerical method development and long-term large-scale computer simulations of Solar System dynamics, evolution, and chaos.

Nanotechnology’s economic impacts and full lifecycle assessments

A paper presented at the International Symposium on Assessing the Economic Impact of Nanotechnology, held March 27 – 28, 2012 in Washington, D.C advises that assessments of the economic impacts of nanotechnology need to be more inclusive. From the March 28, 2012 news item on Nanowerk,

“Nanotechnology promises to foster green and sustainable growth in many product and process areas,” said Shapira [Philip Shapira], a professor with Georgia Tech’s [US]  School of Public Policy and the Manchester Institute of Innovation Research at the Manchester Business School in the United Kingdom. “Although nanotechnology commercialization is still in its early phases, we need now to get a better sense of what markets will grow and how new nanotechnology products will impact sustainability. This includes balancing gains in efficiency and performance against the net energy, environmental, carbon and other costs associated with the production, use and end-of-life disposal or recycling of nanotechnology products.”

But because nanotechnology underlies many different industries, assessing and forecasting its impact won’t be easy. “Compared to information technology and biotechnology, for example, nanotechnology has more of the characteristics of a general technology such as the development of electric power,” said Youtie [Jan Youtie], director of policy research services at Georgia Tech’s Enterprise Innovation Institute. “That makes it difficult to analyze the value of products and processes that are enabled by the technology. We hope that our paper will provide background information and help frame the discussion about making those assessments.”

From the March 27, 2012 Georgia Institute of Technology news release,

For their paper, co-authors Shapira and Youtie examined a subset of green nanotechnologies that aim to enable sustainable energy, improve environmental quality, and provide healthy drinking water for areas of the world that now lack it. They argue that the lifecycle of nanotechnology products must be included in the assessment.

I was hoping for a bit more detail about how one would go about including nanotechnology-enabled products in this type of economic impact assessment but this is all I could find (from the news release),

In their paper, Youtie and Shapira cite several examples of green nanotechnology, discuss the potential impacts of the technology, and review forecasts that have been made. Examples of green nanotechnology they cite include:

  • Nano-enabled solar cells that use lower-cost organic materials, as opposed to current photovoltaic technologies that require rare materials such as platinum;
  • Nanogenerators that use piezoelectric materials such as zinc oxide nanowires to convert human movement into energy;
  • Energy storage applications in which nanotechnology materials improve existing batteries and nano-enabled fuel cells;
  • Thermal energy applications, such as nano-enabled insulation;
  • Fuel catalysis in which nanoparticles improve the production and refining of fuels and reduce emissions from automobiles;
  • Technologies used to provide safe drinking water through improved water treatment, desalination and reuse.

I checked both Philip Shapira‘s webpage and Jan Youtie‘s at Georgia Tech to find that neither lists this latest work, which hopefully includes additional detail. I’m hopeful there’ll be a document published in the proceedings for this symposium and access will be possible.

On another note, I did mention this symposium in my Jan. 27, 2012 posting where I speculated about the Canadian participation. I did get a response (March 5, 2012)  from Vanessa Clive, Nanotechnology File, Industry Sector, Industry Canada who kindly cleared up my confusion,

A colleague forwarded the extract from your blog below. Thank you for your interest in the OECD Working Party on Nanotechnology (WPN) work, and giving some additional public profile to its work is welcome. However, some correction is needed, please, to keep the record straight.

“It’s a lot to infer from a list of speakers but I’m going to do it anyway. Given that the only Canadian listed as an invited speaker for a prestigious (OECD/AAAS/NNI as hosts) symposium about nanotechnology’s economic impacts, is someone strongly associated with NCC, it would seem to confirm that Canadians do have an important R&D (research and development) lead in an area of international interest.

One thing about this symposium does surprise and that’s the absence of Vanessa Clive from Industry Canada. She co-authored the OECD’s 2010 report, The Impacts of Nanotechnology on Companies: Policy Insights from Case Studies and would seem a natural choice as one of the speakers on the economic impacts that nanotechnology might have in the future.”

I am a member of the organizing committee, on the OECD WPN side, for the Washington Symposium in March which will focus on the need and, in turn, options for development of metrics for evaluation of the economic impacts of nano. As committee member, I was actively involved in identifying potential Canadian speakers for agenda slots. Apart from the co-sponsors whose generosity made the event possible, countries were limited to one or two speakers in order to bring in experts from as many interested countries as possible. The second Canadian expert which we had invited to participate had to pull out, unfortunately.

Also, the OECD project on nano impacts on business was co-designed and co-led by me, another colleague here at the time, and our Swiss colleague, but the report itself was written by OECD staff.

I did send (March 5, 2012)  a followup email with more questions but I gather time was tight as I’ve not heard back.

In any event, I’m looking forward to hearing more about this symposium, however that occurs, in the coming weeks and months.

Electrochromic windows and censorship/communication deficiencies

It was an unexpected response to a series of follow-up questions about electrochromic windows at the University of British Columbia’s (UBC) Centre for Interactive Research on Sustainability (CIRS) that has* given me the excuse to discuss censorship and science in Canada.

I’ll start with the windows. I participated in a pre-AAAS (American Association for the Advancement of Science) 2012 annual meeting event in February held by the University of British Columbia. The event was a tour of UBC’s relatively new (opened Nov. 2011) CIRS facility. It was very popular and there were at least 40 of us present.Here’s a little more information from the CIRS About page,

CIRS activities have a regional focus and a global reach. Located on the UBC campus in Vancouver, British Columbia, CIRS is a hub of excellence around green design and building operations practices. We bring thought leaders from UBC and our region together to create and test solutions that work at home, and then share our experiences and knowledge with the public and professionals from across our province and around the world. [emphasis mine] A typical day at CIRS generates many interesting conversations and ideas.

Documenting our activities and communicating our lessons and successes are priorities at CIRS.

We use this website as our primary communication vehicle, showcasing the building design and construction process and the exciting research underway at CIRS. Through this website we aim to build a community of professional and interested people who can connect, share ideas and further accelerate sustainability. [emphasis mine]

We also connect with individuals face-to-face as much as possible through symposiums, workshops, building tours and other events held in the interactive spaces at CIRS.

During the course of the tour there was some discussion about community-building, outreach, etc. and we were informed that the facility is testing a couple of electrochromic windows, amongst other things. Later, I did ask for more information about the electrochromic windows at CIRS and was promptly rewarded with this from Ann L. Campbell,

My colleague Brian Lin passed along your question regarding the electrochromic windows at UBC. Here is the response I received from Alberto Cayuela, the Associate Director of CIRS. He kindly answered my question (what are these windows?) as well as your question regarding their use at CIRS:

We have a limited number of electrochromic windows in the building (fourth floor southwest corner). We are planning to do some research on them in partnership with BC Hydro. Essentially this technology enables the glass to darken or light when a low-voltage electric current is applied to the glass. There are energy benefits associated with blocking or letting heat through windows depending on the time of the year and desired outcome.

I invite you to join the community at www.cirs.ubc.ca where we will post research projects and results as they are undertaken.

The answer excited my curiosity since I’ve written about ‘smart’ windows a number of times, most recently in a Sept. 16, 2011 posting about Boris Lamontagne’s work at the Canada National Research Council and in a Sept. 7, 2011 posting about WANDA, the nanocrystal robot and its role in one of the US Dept. of Energy’s projects with electrochromic windows so I sent back more questions.

After waiting two weeks for a reply, I resent the questions and got a response this morning,

Dear Maryse,

I’m sorry that we are not going to be able to help you with your questions right now. There is no other information available beyond what I sent previously and what is in the online CIRS Technical Manual (and I know that is not much).

Good luck with your blog. I’m sorry we are not able to contribute.

Warm regards,

Ann

Ann L. Campbell
Manager of Communications
UBC Sustainability Initiative

They aren’t able to answer these questions, eh? From my Feb. 21 and March 6, 2012 email request:

Perhaps you could direct me to someone who could answer more specific questions about these windows for publication in my blog. It’s a topic I’ve mentioned on a number of occasions and am hugely excited to hear about this research. Here are the questions:

Who is answering these questions? (Perhaps include a brief bio.?)

Are these windows both electrochromic & photochromic?

Where did you get these windows from and what specific technology do they demonstrate? Could you describe that technology in more detail? e.g. Switch Materials, a local company offers electrochromic and photochromic films for windows or Boris Lamontagne at the NRC has a project with glass that includes curling electrodes, etc.

Exactly how big are these electrochromic windows and what percentage of the windows in the CIRS are electrochromic?

What kind of research are you doing with regard to these windows? Are you measuring their effectiveness, their aesthetic impact, the quality of light and its impact on wellbeing, etc.?

How many pilot programmes for electrochromic/photochromic windows are there in BC? (Is the one at CIRS the only one?)

Is BC Hydro hoping to encourage consumer use of these windows? Are they hoping this is the wave of the future?

I’m not sure why they weren’t willing answer at least a few of these questions, which seem relatively unexceptional, or even supply a reason of some kind for the failure to share information. It seems odd given their mandate which emphasizes outreach and communication.

I did look at the technical manual for the building and Campbell quite correctly noted that it doesn’t provide answers to my questions. I checked the information on lighting and searched for the terms ‘windows’ and ‘electrochromic windows’ in the building manual (the search function does not seem to be working).

The response from Campbell is a pretty standard bureaucratic response (I must give her credit for being significantly more polite than many others). The problem starts with the organization’s stated mandate of  ‘sharing’. I am assuming the intentions are good but the execution is a problem as it often is with mandates that include words such as  ‘sharing’, ‘interactivity’, ‘openness’, and/or ‘community building’, etc. in situations where that is not always possible.

There is another issue: a communications manager is acting as an interface or gatekeeper to the scientists. Note:  I’m not familiar with UBC or CIRS policies regarding direct contact with scientists. Campbell may have been acting as an interface or gatekeeper as a consequence of my initial request which was made to Brian Lin of UBC’s Public Affairs group, although the result seems roughly the same whether Campbell’s role as gatekeeper was intentional or accidental. It should be noted that she never explicitly denied access to a scientist and even if I did get access, there is no guarantee I would have received any answers (scientists aren’t always willing to talk). Still, could Campbell’s response be described as censorship? Before I try to answer that question, I’m going to touch on another situation.

Over the last few years the Canadian government has intentionally instituted a new strategy of insisting a communications professional act as an interface to government scientists. This ‘new’ practice has become a sore point for Canadian journalists who have described it as ‘muzzling scientists’. I certainly haven’t been happy about this added hurdle to getting questions answered as I noted most recently in my Jan. 24, 2012 posting but I’m still considering whether the practice could be described as censorship or not.

The AAAS 2012 annual meeting in Vancouver hosted an event about the ‘science muzzle’ and it was SRO (standing room only). I didn’t attend largely because it had a certain fevered quality I associate with mobs but it has stimulated a fair degree of discussion. Here’s a description of the session from the Professional Institute of the Public Service of Canada webpage titled Unmuzzling Government Scientists,

 Across Canada, journalists are being denied access to publicly funded scientists and the research community is frustrated with the way government scientists are being muzzled. Some observe that it is part of a trend that has seen the Canadian government tighten control over how and when federal scientists interact with the media. As a result, media inquiries are delayed, and scientists are less present in coverage of research in Canada.

In 2008, Environment Canada ordered its scientists to refer all media queries to Ottawa, where communications officers and strategists would decide if the scientist could respond and help craft “approved media lines”.

Stories written for the CBC, Postmedia news, the journal Nature and others have then revealed how these communication restrictions had spread to other government departments.

And the situation is somewhat similar in the United States. A recent article in the Columbia Journalism Review details how restrictive practices established by George W. Bush’s administration still hold under the current government.

This panel will be an occasion to better understand the friction between the media and the governments.

Are the tightened communication strategies symptomatic of a worldwide trend in public and private sectors? Are they justified?

How do obstructions in communications with scientists compromise science research progression and undermine democracy? And in the end, what can be done to improve the situation? 

The February 17, 2012 posting on the Scientific Canadian blog provides some insight into these ‘obstructions’ (I have removed some links),

 I’ve had my own experiences with the phenomenon. Last spring, I interviewed Environment Canada scientist David Tarasick about how cold stratospheric temperatures led to more ozone depletion than usual in 2011. Although he was quite willing to talk to me, government policy required my questions to be submitted in advance by e-mail, and his written responses vetted by Environment Canada’s media relations department; I never did speak to him in person, and couldn’t ask any follow-up questions. More importantly, the whole process took about two weeks. If I had been writing for a daily publication instead of a monthly, the delay would have been unacceptably long. By contrast, his co-author on the paper, the University of Toronto’s Kaley Walker, was able to talk to me on the phone within 24 hours. But I was lucky; a few months later Postmedia News was prevented from speaking with Tarasick altogether.

Even though Environment Canada communication professionals eventually refused access to Tarasick, does that action constitute censorship? According to David Bruggeman’s Mar. 3, 2012 posting on his Pasco Phronesis blog, the answer is no,

 I am not trying to defend the Canadian government.  There is plenty to disagree with about their policies of limiting the dissemination of government conducted research results.  But because they allow this research to be published, the problem is one of transparency, and not of censorship. It doesn’t help those seeking to change the policies to call the bad behavior something it isn’t.  Utilize Canadian open records and open government laws (whatever might be the equivalent of the Freedom of Information Act) to fight for the information.

It might be helpful to know this about David Bruggeman, from Pasco Phronesis blog About page,

I have over 12 years experience in U.S. federal science and technology policy, conducting research and analysis in many subjects for the National Academies and other organizations while slogging through grad school. My education is in Politics (B.A.), Science, Technology, and Public Policy (M.A.), and Science and Technology Studies (need to write that Ph.D. dissertation). I currently work and blog for the Association for Computing Machinery as its Senior Public Policy Analyst.  (Disclaimer – opinions expressed here are strictly my own.)

I do agree with David’s call for clarity but I’m inclined to consider the ‘muzzle’ as a type of de facto censorship. While the research is published, as David notes, it is usually written in language that renders it inaccessible to virtually anyone who’s not an expert in that field. Reporters and other science communicators such as bloggers often act as translators of highly specialized and, at times, obscure research for a variety of audiences.

Direct access to the scientist or expert researcher allows the reporter/communicator to clarify and better understand the materials as they translate it for other audiences, particularly non expert audiences. Without direct access, the act of translation becomes highly difficult if not impossible. As a direct consequence, you have de facto censorship from every audience other than expert audiences.

Here’s the definition of censorship I found at Wikipedia,

 Censorship is the suppression of speech or other public communication which may be considered objectionable, harmful, sensitive, or inconvenient to the general body of people as determined by a government, media outlet, or other controlling body.

Given that definition and getting back to Campbell and her response to my electrochromic window questions, then it could be described as censorship if she’s withholding information (again, she did not refuse access to scientists [she contacted Alberto Cayuela for the first response], which differentiates this from the Environment Canada example). It is possible, although not likely, that the CIRS team does not have the information I requested in my follow up questions.

While I don’t like being on the receiving end, I do believe there are some situations where censorship is indicated. I’m not convinced that’s the case with the electrochromic windows at the CIRS but I am willing to entertain the possibility.

ETA March 9, 2012: Here’s a posting by Leigh Bedon (March 8, 2012) on Techdirt about the issue of the government limiting media access to scientists. The title, Canadians To Prime Minister: Don’t Censor Our Scientists, hints at Bedon’s perspective.

Discover Canadian innovation by staring deeply into your own navel and Mike Laziridis discusses manure (really) at the AAAS Fri., Feb. 17, 2012 afternoon events

It was an afternoon event (1:30 – 4:30 pm PST) at the American Association for the Advancement (AAAS) 2012 meeting in Vancouver, “Searching for the Right Space for Innovation.” I realized it was going to be a bunch of academics discussing their research about the Canadian scene; I just didn’t expect it to be so thoroughly self-involved. There was one moment of extreme excitement with everyone madly scribbling or keyboarding. David Wolfe from the University of Toronto mentioned that there is interest is funding risk science research and centres (apparently the Univ. of Toronto is about to open a risk science centre of its own). I’m pretty sure it was the smell of money that occasioned all the activity.

Given that this meeting attracts mainly US scientists and others from outside Canada, I was hoping for a more expansive view of Canadian innovation (the good, the bad, and the ugly). The relentless focus on the minutiae surprised me. I realize that for these academics what I perceive to be minutiae is vitally important. (That’s always true  if you are deeply involved in a topic. I feel much the same way about passive and active voices but the only people who care to discuss this topic at length [I mean 20 or more minutes; occasionally you meet someone who’s prepared to argue you {the writer} into the ground but they usually lose interest as the discussion continues] are other writers.)

Given that the AAAS meeting is attracting academics from many different disciplines and from jurisdictions outside Canada, I found this discussion disappointing in its provincialism.

This session was followed by the big event of the day, the plenary lecture by Mike Lazaridis billed as “The Power of Ideas.” One of the founders of Research in Motion (RIM), the company that produced the Blackberry, Lazaridis is well known as a successful technology innovator. He recently stepped down (or was pushed) from his position (with Jim Balsillie) as co-president and co-CEO of RIM after a very bad year (2011) for that company.

In technology circles, there’s a phenomenon where the people who founded the company can grow it to a certain point but no further. Lazaridis and Balsillie grew their company well past the point where most Canadian entrepreneurs have to quit. RIM is quite an extraordinary accomplishment by any standard internationally and I’m not sure why Lazaridis and/or his handlers feel they have to gild it past levels considered tasteful by baroque standards.

Lazaridis is a good speaker and I wish the material had been better. I’m referring specifically to the part where he posed a thought experiment (his term for it) whereby the Blackberry is sent back in time to some giants in the field electronics, Michael Faraday and James Clerk Maxwell.Is there anyone who doesn’t realize that these 19th century geniuses would be hard put to understand the device?As for sending back some textbooks so they could read about the technology, unlike Lazaridis I’m not convinced that would be helpful. Apparently Lazaridis learned technology by reading the technical manuals first. Laziridis has a different starting point than either of these geniuses not least of which was a cultural context that allowed him to grapple with what was then a ‘new’ technology.

Lazaridis did announce that there will be a new centre opening, the Mike and Ophelia Lazaridis Quantum Nano Centre (QNC) at the University of Waterloo (Ontario, Canada). I gather the new opening date is later this year (2012);  it was supposed to open during summer 2011.

There were some charming bits to the talk (high school experiences) and he’s charismatic. As for the manure, this was mentioned in the context of the first urban planning meeting ever held in the 1890’s in New York City. Lazaridis set this up as a joke asking us what we thought the big problem of the 1890’s urban environment could be. I imagine it was meant as a launch point for something more germane to the ‘big ideas’ theme but I knew the punchline (I happened to see an episode of Nova where this information was featured), was tired, and Lazaridis does not appear to have a gift for delivering a comic line so I left. There you have it: day one.

ArboraNano in Washington, DC for a two-day shindig on nanotechnology and economic impacts

The Organization for Economic Cooperation and Development (OECD), the American Association for the Advancement of Science (AAAS), and the US National Nanotechnology Initiative (NNI) are hosting an  International Symposium on Assessing the Economic Impact of Nanotechnology, March 27 – 28, 2012 in Washington, D.C. Registration for the event opens Feb. 10, 2012 (first come, first served) and it appears to be a free event.

From the NNI’s event page, here’s some information about their objectives and who they’re inviting to attend,

The objective of the symposium is to systematically explore the need for and development of a methodology to assess the economic impact of nanotechnology across whole economies, factoring in many sectors and types of impact, including new and replacement products and materials, markets for raw materials, intermediate and final goods, and employment and other economic impacts.

Attendees are being invited from a broad spectrum of backgrounds and expertise, including technology leaders, key decision makers, economists, investors, policy analysts, scientists and engineers from industry, business, government, academia, and the general public.

They have close to 40 confirmed speakers for this event and, interestingly (for a Canadian and/or someone interested in nanocrystalline cellulose), one of them is Reinhold (Ron) Crotogino of ArboraNano.

Crotogino, network director, president and chief executive officer (CEO) of ArboraNano, the Canadian Forest NanoProducts Network, has extensive experience and education in the forest products industry. From a Feb. 10, 2011 news item in Pulp & Paper Canada,

Crotogino is a graduate of the University of British Columbia (B.A.Sc. 1966) and McGill University (Ph.D. 1971), both in chemical engineering. He worked with Voith for a few years after graduating, but spent much of his career as a researcher and research manager with Paprican (now FPInnovations). [emphasis mine]

For anyone not familiar with the nanocrystalline cellulose (NCC) story in Canada, FPInnovations initiated and has been heavily involved in the development of NCC. (My Dec. 15, 2011 posting features one of my more recent stories about NCC in Canada.)

It’s a lot to infer from a list of speakers but I’m going to do it anyway. Given that the only Canadian listed as an invited speaker for a prestigious (OECD/AAAS/NNI as hosts) symposium about nanotechnology’s economic impacts, is someone strongly associated with NCC, it would seem to confirm that Canadians do have an important R&D (research and development) lead in an area of international interest.

One thing about this symposium does surprise and that’s the absence of Vanessa Clive from Industry Canada. She co-authored the OECD’s 2010 report, The Impacts of Nanotechnology on Companies: Policy Insights from Case Studies and would seem a natural choice as one of the speakers on the economic impacts that nanotechnology might have in the future.

ETA March 29, 2012: Vanessa Clive did contact me to clarify the situation and her response has been included in my March 29, 2012 follow up posting. (scroll down approximately 1/2 way)

For anyone who wants to see the agenda before committing, here’s the link. I did take a look,

Session One: Setting the Scene

This plenary session will introduce the conference themes, objectives and expected outputs. The session will provide an overview of the technologies and challenges that impact the assessment of the economic impact of nanotechnology and some indications of metrics being used

[break]

Session One con’t: Government Panel Discussion

This panel session will consider the issues raised in Session One, with a focus on the particularities of each country in addressing the challenges in assessing the economic impact of nanotechnology [emphasis mine]

I would have appreciated a little more detail such as which speakers will be leading which session and when they say “each country” exactly which countries do they mean? Oddly, no one involved with this event thought about phoning me to ask my opinion.

Mike Lazaridis (Blackberry) at AAAS 2012 in Vancouver next month?

Set to appear on Friday, Feb. 17, 2012 as a plenary speaker at the American Association for the Advancement of Science (AAAS) annual meeting, Mike Lazaridis will be speaking about The Power of Ideas.

Lazaridis’ presence (assuming he shows up) is likely to add a frisson of excitement given today’s announcement that he is stepping down as co-chief executive officer (CEO) of the company he helped found, Research in Motion (RIM) which produces the Blackberry mobile device. (Thorsten Heins, a four-year employee with the company and former Siemens AG executive, will be RIM’s new CEO.)

I was intrigued months ago when I saw Laziridis was scheduled to speak partly because of his company’s importance and current travails, partly due to his connection to the Perimeter Institute for Theoretical Physics (as I recall he provides/ed much of the institute’s funding), and partly his communication strategies.

I’m inferring from the little I’ve been able to observe that Lazaridis does not perform well when criticized or attacked. There was a court case back in 2001 in the US, where Lazaridis seems to have engaged in a ‘pissing contest’ with a company I’ve often seen described as a patent troll, NTP Incorporated. I gather he initially dismissed the litigation as frivolous (did he dare them to sue?). Unfortunately he did that publicly, never a good idea when you’re engaged in a court case where people are likely to read your comments in the press. Five years later, RIM lost the case and had to pay NTP over a complicated legal argument (you can read more about that here). Frankly, it seems wrong that RIM should have had to pay money to a company that files patents for the sole purpose of suing other companies.

I’d dismiss the incident but, more recently, it took Lazaridis too long to apologize for a major service outage. In October 2011, service was lost by customers in Europe and elsewhere for three days before an apology was forthcoming. Interestingly, that was around the time the outage began to affect North American customers. Also, he’s been far less visible publicly over the last few months. (Note: Lazaridis has tended to be the public face/spokesperson for RIM, while Jim Balsillie, his co-CEO) had performed that function less frequently.)

I am looking forward to how Lazaridis performs in Vancouver in February 2012 at the AAAS meeting (Feb. 16-20).

Vancouver’s AAAS (American Association for the Advancement of Science) 2012 meeting preview

This morning (Jan. 19, 2012) Vancouver (or media types and various guests) were treated to what was billed as a ‘preview’ of the AAAS (American Association for the Advancement of Science) 2012 meeting in Vancouver from Feb. 16-20, 2012.

The preview was well organized and proceeded quite smoothly although I’m not sure about its actual purpose. Generally, a press conference of this type is called to generate excitement and interest. The idea being that the now excited and interested media will report on the preview and upcoming event and pass that excitement and interest on to their various audiences. The process doesn’t stop there.

Our now excited and interested audiences are demanding more information about this event which drives the media to report about the event itself, generating excitement and interest in all the parties that keeps growing and developing throughout all of time.

There were a few moments in the preview where excitement and interest threatened to make an appearance. Julio Montaner, Director of the BC Centre for Excellence in HIV/AIDS, and Karen Bakker, a Canada Research Chair in Political Ecology at the University of  British Columbia, spoke with passion and fervour about their areas of expertise and for a few moments the room buzzed quietly. Happily, they will be both speaking at the AAAS 2012 meeting next month.

There was one other frisson of excitement. Richard Lee, MLA (member of the legislative assembly of British Columbia) for Burnaby North and a physicist, talked about the 200 students from schools in British Columbia (BC) who received a free pass for the meeting and a membership to the AAAS courtesy of the BC Innovation Council (BCIC) and the government of BC.

Otherwise, the preview was a bit lacklustre. They kept mentioning that Canada is world leader in some research areas without mentioning anything much other than health, specifically Montaner’s work. I was somewhat perturbed by the lack of specifics. Canada is not a world leader in many areas of science so why not mention them?

I was speaking to someone afterwards and noted that research in nanocellulose (specifically, nanocrystalline cellulose [NCC}) is an area where we shine (for now). His response was something along these lines “Not all the special interests can be mentioned.” Again, Canada doesn’t have that many research areas where it leads so, why not mention them? Of course, he’s a physicist and that area of research, nanocellulose, is more biology/chemistry.

Basically, I’m a little disappointed they didn’t use a little more imagination and creativity to produce this press event. I appreciate that the politicians and other officials need to be given their moment but something as silly as having that professor at the University of British Columbia who dresses up and performs as Charles Darwin make an appearance would have livened the proceedings.

I hope this preview is not a harbinger of the entire 2012 meeting experience. There is one ray of imagination, Meet the Scientists! events (Family Science Days), which will take place over two days. For example, there will be The Real Science of Alien Worlds, Indigenous Mathematics, Biodiversity Game: The Phylo Project, etc. (I got this information from a handout that was made available at the press conference.)

The meeting sessions themselves promise to be quite exciting because the AAAS does provide a broad exposure to all kinds of scientific research. By comparison, most scientific meetings are organized around a specialty, e. g., chemistry. (If you’re curious about the AAAS 2012 sessions, you can go here to browse the programme.)

The Vancouver Aquarium hosted this morning’s event and for that, I thank them. I got to touch a sea jelly (formerly, jelly fish) and talk to a few folks about the Arctic, the animals that live in the sea and/or on the ice, and the politics of the situation. It was, all in all, an unexpected treat.

ETA Jan. 22, 2012: I have added links to webpages for the AAAS 2012 meeting, Julio Montaner, and Karen Bakker. I also included a sentence stating where I received the information about the events for families.

CelluForce (nanocrystalline cellulose) plant opens

Before launching into the news about its manufacturing plant, here’s a little information about the company itself, CelluForce, a joint venture between FPInnovations and Domtar, from the About CelluForce page,

The company is a joint venture of Domtar Corporation and FPInnovations and was created to manufacture NCC in the world’s first plant of its kind, located in Windsor, Québec.

I wrote about CelluForce in my June 6, 2011 posting around the time it was launched and now its raison d’être, the manufacturing plant, is operational. From the Dec. 13, 2011 news item on Nanowerk,

Members of the board, management and employees of CelluForce are pleased to announce the end of the construction phase and the start of operations at the first manufacturing plant for NanoCrystalline Cellulose (NCC) in the world.

For the last eight weeks, CelluForce has been progressively starting up the equipment for the first ever large-scale production of NCC. The nanomaterial will be produced in state-of-the-art facilities located at Domtar’s pulp and paper plant in Windsor, Quebec. Construction extended over a fourteen-month period. It required a total investment of $36M including the financial participation of both the Federal and Québec governments. The company is particularly pleased to have completed construction phase on time.

CelluForce President and CEO Jean Moreau declared, “Wood pulp is being delivered to the plant to test the new equipment and we are making progress on a daily basis. NCC will start to be produced by the end of the year, with production gradually increasing until it reaches a steady rhythm of 1,000 kg per day in 2012”.

For anyone who’s unfamiliar with NanoCrystalline Cellulose (NCC), I posted an interview with Dr. Richard Berry of FPInnovations who kindly answered some very basic questions on NCC in my Aug. 27, 2010 posting.

The opening of the CelluForce manufacturing plant is very exciting news given that Canadians have a worldwide lead in this research area. Being able to produce NCC in amounts that are meaningful at an industrial scale will make research easier not just in Canada but elsewhere too.

From the news item on Nanowerk,

CelluForce will, on a worldwide basis, market NanoCrystalline Cellulose for strength applications under the CelluForce Impact™ brand, and for optical applications of NCC under the CelluForce Allure™ brand.

I don’t think this video adds much information but it is very slick and entertaining,

Here’s a listing of applications that NCC can be used to produce (from the CelluForce Applications page),

NCC’s properties and many potential forms enable many uses, including:

  • Biocomposites for bone replacement and tooth repair
  • Pharmaceuticals and drug delivery
  • Additives for foods and cosmetics
  • Improved paper and building products
  • Advanced or “intelligent” packaging
  • High-strength spun fibres and textiles
  • Additives for coatings, paints, lacquers and adhesives
  • Reinforced polymers and innovative bioplastics
  • Advanced reinforced composite materials
  • Recyclable interior and structural components for the transportation industry
  • Aerospace and transportation structures
  • Iridescent and protective films
  • Films for optical switching
  • Pigments and inks
  • Electronic paper printers
  • Innovative coatings and new fillers for papermaking

One of the most notable attributes of this material is that it can be used to form iridescent coloured films that can be adjusted precisely, making it possible to revolutionize many applications, including, among others;

  • Security papers
  • Iridescent pigments
  • Switchable optical filters and barriers
  • Sunscreens
  • Cosmetics
  • Packaging
  • Coatings

I hope to hear more about CelluForce and its efforts with NCC.

On a somewhat related note, I wonder what’s happening with the NCC efforts in Alberta? I noted in my July 5, 2011 posting that an NCC pilot plant was being opened in that Canadian province but I haven’t heard anything since.

I also noted that there is going to be a session titled NanoCellulose: An Abundant, Sustainable, Versatile Biopolymer at the American Association for the Advancement of Science (AAAS) annual meeting in Vancouver this February 2012 featuring a researcher from Alberta.

Here’s the session description and speakers,

Saturday, February 18, 2012: 3:00 PM-4:30 PM

Room 220 (VCC West Building)

Nanocellulose is a generic name for a new family of novel fibrils derived from plant cell walls or bacteria. Just as cellulose has been an abundant natural resource for millennia with substantial contributions to the development of civilizations, the unique nanocelluloses are sustainable biopolymers poised to have a major role in improving the quality of human life in this century. A rapidly expanding field of nanocellulose science has emerged with pioneering results, leading some to predict that the field could parallel history, where the 1920s studies on cellulose contributed to the discovery of polymers and led to the origin of polymer science. Fibrillated, crystalline, and bacterial nanocelluloses have unsurpassed versatility and strength for composite materials, films, medical implants, drug delivery systems, and a biomaterial rivaling Kevlar, which is made from fossil fuels. With cellulosic biofuels becoming a competitive alternative to fossil fuels, research in enzymology is targeting high-value nanofibrillated cellulose as a biofuel co-product. This symposium will present current findings that bridge multidisciplines, from genomics of tree and plant breeding, plant cell wall structure and function, advanced techniques for characterizing cell walls and nanocellulose, and specialized methods for isolating nanofibrils, to novel biomaterials. The speakers represent three international science and technology centers at the forefront of this new wave of cellulose research.

Organizer:

Barbara Illman, U.S. Forest Service

Moderator:

Barbara Illman, U.S. Forest Service

Speakers:

Theodore Wegner, U.S. Forest Service
A World View of Nanocellulose

Nils Petersen, National Research Council Canada
Nano-Scale Devices for Nanocellulose

Ali Harlin, VTT Technical Research Center of Finland
Nanocellulosic Technologies: A Success Story

It looks interesting but I would have liked to have heard from an FPInnovations researcher and the Brazilian researchers who are working on nanocellulose fibres from pineapples and bananas (my Mar. 28, 2011 and June 16, 2011 postings) and Israeli researchers who are working on NCC foams (my Aug. 2, 2011 posting). These panels are always difficult to organize as you try to get everyone in the same room at the same time although the panel does seem to be focused on wood products as a source for NCC.  (If you search Ali Harlin on LinkedIn, you’ll find paper and wood products are Harlin’s area of expertise.)

I notice Nils Petersen, one of the speakers, who in addition to being a National Research Council (NRC) scientist is also the Director General for Canada’s National Institute of Nanotechnology located in Alberta.
