Nanoscale light confinement without metal (photonic circuits) at the University of Alberta (Canada)

To be more accurate, this is a step forward towards photonic circuits according to an Aug. 20, 2014 news item on Azonano,

The invention of fibre optics revolutionized the way we share information, allowing us to transmit data at volumes and speeds we’d only previously dreamed of. Now, electrical engineering researchers at the University of Alberta are breaking another barrier, designing nano-optical cables small enough to replace the copper wiring on computer chips.

This could result in radical increases in computing speeds and reduced energy use by electronic devices.

“We’re already transmitting data from continent to continent using fibre optics, but the killer application is using this inside chips for interconnects—that is the Holy Grail,” says Zubin Jacob, an electrical engineering professor leading the research. “What we’ve done is come up with a fundamentally new way of confining light to the nano scale.”

At present, the diameter of fibre optic cables is limited to about one thousandth of a millimetre. Cables designed by graduate student Saman Jahani and Jacob are 10 times smaller—small enough to replace copper wiring still used on computer chips. (To put that into perspective, a dime is about one millimetre thick.)

An Aug. 19, 2014 University of Alberta news release by Richard Cairney (also on EurekAlert), which originated the news item, provides more technical detail and information about funding,

 Jahani and Jacob have used metamaterials to redefine the textbook phenomenon of total internal reflection, discovered 400 years ago by German scientist Johannes Kepler while working on telescopes.

Researchers around the world have been stymied in their efforts to develop effective fibre optics at smaller sizes. One popular solution has been reflective metallic claddings that keep light waves inside the cables. But the biggest hurdle is increased temperatures: metal causes problems after a certain point.

“If you use metal, a lot of light gets converted to heat. That has been the major stumbling block. Light gets converted to heat and the information literally burns up—it’s lost.”

Jacob and Jahani have designed a new, non-metallic metamaterial that enables them to “compress” and contain light waves in the smaller cables without creating heat, slowing the signal or losing data. …

The team’s research is funded by the Natural Sciences and Engineering Research Council of Canada and the Helmholtz-Alberta Initiative.

Jacob and Jahani are now building the metamaterials on a silicon chip to outperform current light confining strategies used in industry.

Given that this work is being performed at the nanoscale and these scientists are located within the Canadian university which houses Canada’s National Institute of Nanotechnology (NINT), the absence of any mention of the NINT comes as a surprise (more about this organization after the link to the researchers’ paper).

Here’s a link to and a citation for the paper,

Transparent subdiffraction optics: nanoscale light confinement without metal by Saman Jahani and Zubin Jacob. Optica, Vol. 1, Issue 2, pp. 96-100 (2014) http://dx.doi.org/10.1364/OPTICA.1.000096

This paper is open access.

In a search for the NINT’s website I found this summary at the University of Alberta’s NINT webpage,

The National Institute for Nanotechnology (NINT) was established in 2001 and is operated as a partnership between the National Research Council and the University of Alberta. Many NINT researchers are affiliated with both the National Research Council and University of Alberta.

NINT is a unique, integrated, multidisciplinary institute involving researchers from fields such as physics, chemistry, engineering, biology, informatics, pharmacy, and medicine. The main focus of the research being done at NINT is the integration of nano-scale devices and materials into complex nanosystems that can be put to practical use. Nanotechnology is a relatively new field of research, so people at NINT are working to discover “design rules” for nanotechnology and to develop platforms for building nanosystems and materials that can be constructed and programmed for a particular application. NINT aims to increase knowledge and support innovation in the area of nanotechnology, as well as to create work that will have long-term relevance and value for Alberta and Canada.

The University of Alberta’s NINT webpage also offers a link to the NINT’s latest rebranded website, The failure to mention the NINT gets more curious when looking at a description of NINT’s programmes one of which is hybrid nanoelectronics (Note: A link has been removed),

Hybrid NanoElectronics provide revolutionary electronic functions that may be utilized by industry through creating circuits that operate using mechanisms unique to the nanoscale. This may include functions that are not possible with conventional circuitry to provide smaller, faster and more energy-efficient components, and extend the development of electronics beyond the end of the roadmap.

After looking at a list of the researchers affiliated with the NINT, it’s apparent that neither Jahani or Jacob are part of that team. Perhaps they have preferred to work independently of the NINT ,which is one of the Canada National Research Council’s institutes.

Hemp as a substitute for graphene in supercapacitors

As a member of the Cannabis plant family, hemp has an undeserved reputation due to its cousin’s (marijuana) notoriety and consciousness-altering properties. Hemp is, by contrast, the Puritan in the family, associated by the knowledgeable with virtues of thrift and hard work.

An Aug. 12, 2014 news item on Nanowerk highlights a hemp/supercapacitor presentation at the 248th meeting of the American Chemical Society (ACS),

As hemp makes a comeback in the U.S. after a decades-long ban on its cultivation, scientists are reporting that fibers from the plant can pack as much energy and power as graphene, long-touted as the model material for supercapacitors. They’re presenting their research, which a Canadian start-up company is working on scaling up, at the 248th National Meeting & Exposition of the American Chemical Society (ACS), the world’s largest scientific society.

David Mitlin, Ph.D., explains that supercapacitors are energy storage devices that have huge potential to transform the way future electronics are powered. Unlike today’s rechargeable batteries, which sip up energy over several hours, supercapacitors can charge and discharge within seconds. But they normally can’t store nearly as much energy as batteries, an important property known as energy density. One approach researchers are taking to boost supercapacitors’ energy density is to design better electrodes. Mitlin’s team has figured out how to make them from certain hemp fibers — and they can hold as much energy as the current top contender: graphene.

An Aug. 12, 2014 ACS news release features David Mitlin, formerly of the University of Alberta (Canada) where this research took place,, Mitlin is now with now with Clarkson University in New York,

“Our device’s electrochemical performance is on par with or better than graphene-based devices,” Mitlin says. “The key advantage is that our electrodes are made from biowaste using a simple process, and therefore, are much cheaper than graphene.”

The race toward the ideal supercapacitor has largely focused on graphene — a strong, light material made of atom-thick layers of carbon, which when stacked, can be made into electrodes. Scientists are investigating how they can take advantage of graphene’s unique properties to build better solar cells, water filtration systems, touch-screen technology, as well as batteries and supercapacitors. The problem is it’s expensive.

Mitlin’s group decided to see if they could make graphene-like carbons from hemp bast fibers. The fibers come from the inner bark of the plant and often are discarded from Canada’s fast-growing industries that use hemp for clothing, construction materials and other products. …

His team found that if they heated the fibers for 24 hours at a little over 350 degrees Fahrenheit, and then blasted the resulting material with more intense heat, it would exfoliate into carbon nanosheets.

Mitlin’s team built their supercapacitors using the hemp-derived carbons as electrodes and an ionic liquid as the electrolyte. Fully assembled, the devices performed far better than commercial supercapacitors in both energy density and the range of temperatures over which they can work. The hemp-based devices yielded energy densities as high as 12 Watt-hours per kilogram, two to three times higher than commercial counterparts. They also operate over an impressive temperature range, from freezing to more than 200 degrees Fahrenheit.

“We’re past the proof-of-principle stage for the fully functional supercapacitor,” he says. “Now we’re gearing up for small-scale manufacturing.”

I have not been able to confirm the name for Mitlin’s startup but I think it’s called Alta Supercaps (Alta being an abbreviation for Alberta,, amongst other things, and supercaps for supercapacitors) as per the information about a new startup on the Mitlin Group webspace (scroll down to the July 2, 2013 news item) which can still be found on the University of Alberta website (as of Aug. 12, 2014).

For those who would like more technical details, there is this July 2013 article by Mark Crawford for the ASME (American Society of Mechanical Engineers); Note: A link has been removed.

Activated carbons, templated carbons, carbon nanofibers, carbon nanotubes, and graphene have all been intensively studied as materials for supercapacitor electrodes. High manufacturing costs is one issue—another is that the power characteristics of many of these carbons are limited. This is a result of high microporosity, which increases ion transport limitations.

“It is becoming well understood that the key to achieving high power in porous electrodes is to reduce the ion transport limitations” says Mitlin. “Nanomaterials based on graphene and their hybrids have emerged as a new class of promising high-rate electrode candidates—they are, however, too expensive to manufacture compared to activated carbons derived from pyrolysis of agricultural wastes, or from the coking operations.”

Biomass, which mainly contains cellulose and lignin by-products, is widely utilized as a feedstock for producing activated carbons. Mitlin decided to test hemp bast fiber’s unique cellular structure to see if it could produce graphene-like carbon nanosheets.

Hemp fiber waste was pressure-cooked (hydrothermal synthesis) at 180 °C for 24 hours. The resulting carbonized material was treated with potassium hydroxide and then heated to temperatures as high as 800 °C, resulting in the formation of uniquely structured nanosheets. Testing of this material revealed that it discharged 49 kW of power per kg of material—nearly triple what standard commercial electrodes supply, 17 kW/kg.

Mitlin and his team successfully synthesized two-dimensional, yet interconnected, carbon nanosheets with superior electrochemical storage properties comparable to those of state-of-the-art graphene-based electrodes. “We were able to achieve this by employing a biomass precursor with a unique structure—hemp bast fiber,” says Mitlin. “The resultant graphene-like nanosheets possess fundamentally different properties—such as pore size distribution, physical interconnectedness, and electrical conductivity—as compared to conventional biomass-derived activated carbons.”

It seems to me that over the last few months there have been more than the usual number of supercapacitor stories, which makes the race to create the one that will break through in the marketplace fascinating to observe.

Xerox Research Centre Canada, authentic currency, etc. and a ‘nano’ deal with Authentix

An April 1, 2014 news item on labcanada.com describes a recently signed deal which may turn up the competition in Canada’s currency authentication business sector,

The Xerox Research Centre Canada [XRCC] says it has signed a multi-year materials research services agreement with Dallas-based Authentix, a provider of anti-counterfeiting, brand protection and program integrity solutions for the oil and gas industry; currency, branded products and tax stamp markets.

“Working with companies like Authentix adds to the value our scientists bring to the research world,” said Paul Smith, vice president and director of the Xerox Research Centre Canada. “Not only do we continue to strengthen our scientific role in Canadian innovation, we are now bringing valuable research capabilities to other companies globally.”

Given that Xerox is a US company with a Canadian branch, I’m not sure how signing a deal with another US company aids Canadian innovation. On the plus side, it does give some Canadian scientists a job.

I also noted the reference to “currency authentication”, which suggests that Authentix could be in direct competition with the Canadian company, Nanotech Security Corp. (I have written about Nanotech Security Corp. previously with the two most recent being a Jan. 31, 2014 posting about the company’s presentation at an Optical Document Security Conference and a March 17, 2014 posting about the company’s first commercial client, TED.) Perhaps Xerox plans to spur Canadian innovation by providing more competition for our technology companies.

Here’s more from the March 31, 2014 Xerox news release, which originated the news item about the deal with Authentix,

Scientists at XRCC specialize in the design and development of electronic materials and specialty components; environmentally-friendly processes; coatings, applied nanotechnology; polymer science, engineering and pilot plant scale-up. [emphasis mine]

“Materials science research makes it possible to bring new levels of security, accuracy and efficiency to product authentication,” said Jeff Conroy, chief technology officer of Authentix.  “Leveraging the core competencies of Xerox’s materials lab in Canada expands and accelerates our ability to bring innovative solutions to the authentication market.”

Located near Toronto, XRCC is part of the global Xerox Innovation Group made up of researchers and engineers in five world-renowned research centers. Each center leverages XRCC’s unique, integrated, global materials research and development mandate.

You can find out more about Authentix here.

Getting back to XRCC, they had a longstanding relationship with Canada’s National Institute of Nanotechnology (NINT) having signed a 2007 contract with NINT and the Government of Alberta, from a Xerox Innovation Story,

In Canada’s first major public-private nanotechnology research partnership, the Xerox Research Centre of Canada (XRCC), NRC National Institute for Nanotechnology (NINT) and Government of Alberta will provide approximately $4.5 million for research and development of materials-based nanotechnology over the next three years.

The three partners will invest funds, human resources, and available infrastructures to create a research program and teams focused on developing commercially successful nanotechnology-based discoveries. Personnel from NINT and XRCC will collaborate on research projects at NINT in Edmonton, Alberta, and at XRCC in Mississauga, Ontario.

The funds will contribute to the hiring of eight to 10 scientists who will investigate materials-based nanotechnologies, including document- and display-related technologies. The research program, co-managed by XRCC and NINT, will allow access to Xerox’s experience in successfully commercializing technology to facilitate the market application of resulting inventions.

“This level of public and private sector partnership helps fuel the type of innovation that will keep Alberta, and Canada as a whole, strong and competitive in an increasingly global, knowledge-based economy,” said Doug Horner, minister for Advanced Education and Technology, Government of Alberta. “The investments from the Government of Alberta, Xerox and NINT will build a world-class nanotechnology research program that embraces the spirit of innovation, but also that of commercialization.”

I find the references to Xerox and innovation and commercialization amusing since the company is famous for its innovation missteps. For example, the company owned the photocopying business from the 1960s into the 1970s due to its patent rights but once those rights ran out (there’s usually a time limit on a patent) the company was poorly equipped to compete. My guess is that they didn’t know how in an environment where they no longer held a monopoly. The other famous story concerns the mouse and the graphical user interface both of which were developed at Xerox but the company never pursued those innovations leaving Stephen Jobs and his colleagues to found Apple.

At any rate, Xerox survived those missteps so perhaps they learned something and they really do mean it when they talk about spurring innovation. Although, given the business model for most Canadian technology companies, I expect Nanotech Security Corp. to get purchased by Authentix or one of its competitors with the consequence that Canadian taxpayers have helped to pay, yet again, for innovation that will be purchased by a corporate entity with headquarters in another country and much less interest in maintaining a business presence in Canada. If you think I’m being cynical about another country’s corporate interests in Canada, take a look at this excerpt from Derrick Penner’s March 28, 2014 article for the Vancouver Sun about Vancouver’s recent Globe 2014 conference,

Globe, the biannual conference on sustainable development [March 26 – 28, 2014], is as much about doing business as it is about discussing bright ideas for reducing the impact of industry on the environment.

And a new twist for European delegates, such as Roumeas [Vincent Roumeas, a business development manager for the Paris Region Economic Development Agency], is the prospect of Canada Europe Free Trade.

Prime Minister Stephen Harper and European Commission President José Manuel Barroso, last October, signed an agreement in principal, which commits the two sides to finalizing a full agreement giving each other tariff-free access to each others’ markets.

Roumeas said it is too soon to tell how much of a draw EU free trade will be because he is working on developing immediate prospects within the next 18 months, which would be before any benefits from free trade would kick in, if the deal is concluded.

However, his colleague Jeremy Bernard Orawiec, a trade adviser for UbiFrance, does see the agreement as an attraction for French firms interested the American market.

He added that the U.S. is viewed as a tough market to crack, so Canada is looked at as an easier-accessed entry point to all of North America.

“It’s really positive to see Canada able to make an agreement before the U.S.,” Orawiec said. “It gives us a time frame so (companies) can come here [Canada] and explore the whole American market.” [emphases mine]

It’s not clear from his comments but I suspect Orawiec is unaware that Mexico is part of North America. In any event, Canada as a market place or as an innovation centre is not important in and of itself. One can criticize Orawiec for making those comments but I’d like to thank him as he has expressed an attitude that I believe is widely held.

Responsible innovation at the Center for Nanotechnology in Society’s (Arizona State University) Virtual Institute

The US National Science Foundation (NSF) has a funding program called Science Across Virtual Institutes (SAVI) which facilitates global communication for scientists, engineers, and educators. From the SAVI home page,

Science Across Virtual Institutes (SAVI) is a mechanism to foster and strengthen interaction among scientists, engineers and educators around the globe. It is based on the knowledge that excellence in STEM (science, technology, engineering and mathematics) research and education exists in many parts of the world, and that scientific advances can be accelerated by scientists and engineers working together across international borders.

According to a Sept. 24, 2013 news item on Nanowerk, the NSF’s SAVI program has funded a new virtual institute at Arizona State University’s (ASU)  Center for Nanotechnology in Societ6y (CNS), Note: Links have been removed,

The National Science Foundation recently announced a grant of nearly $500,000 to establish a new Virtual Institute for Responsible Innovation (VIRI) at the Center for Nanotechnology in Society at ASU (CNS-ASU). In a global marketplace that thrives on technological innovation, incorporating ethics, responsibility and sustainability into research and development is a critical priority.

VIRI’s goal is to enable an international community of students and scholars who can help establish a common understanding of responsible innovation in research, training and outreach. By doing so, VIRI aims to contribute to the governance of emerging technologies that are dominated by market uncertainty and difficult questions of how well they reflect societal values.

VIRI founding institutional partners are University of Exeter (UK), Durham University (UK), University of Sussex (UK), Maastricht University (Netherlands), University of Copenhagen (Denmark), Karlsruhe Institute of Technology (Germany), University of Waterloo (Canada), Oslo and Akershus University College of Applied Sciences (Norway), and State University of Campinas (Brazil).

VIRI founding institutional affiliates are the US National Academy of Engineering’s Center for Engineering, Ethics and Society, IEEE Spectrum Online and Fondazione Giannino Bassetti.

Interesting cast of characters.

The Sept. 23, 2013 ASU news release, which originated the news item, offers some insight into the time required to create this new virtual institute,

Led by ASU faculty members David Guston and Erik Fisher, VIRI will bring a social and ethical lens to research and development practices that do not always focus on the broader implications of their research and products. Guston, director of CNS-ASU, co-director of the Consortium of Science, Policy and Outcomes, and professor in the School of Politics and Global Studies, has been pushing for the establishment of academic units that focus on responsible innovation for years.

“We are thrilled that NSF has chosen to advance responsible innovation through this unique, international collaboration,” Guston said. “It will give ASU the opportunity to help focus the field and ensure that people start thinking about the broader implications of knowledge-based innovation.”

Fisher, assistant professor in the School for Politics and Global Studies, has long been involved in integrating social considerations into science research laboratories through his NSF-funded Socio-Technical Integration Research (STIR) project, an affiliated project of CNS-ASU.

“Using the insights we’ve gained in the labs that have participated in the STIR project, we expect to be able to get VIRI off the ground and make progress very quickly,” Fisher said.

The VIRI appears to be an invite-only affair and it’s early days yet so there’s not much information on the website but the VIRI home page looks promising,

“Responsible innovation” (RI) is an emerging term in science and innovation policy fields across the globe. Its precise definition has been at the center of numerous meetings, research council decisions, and other activities in recent years. But today there is neither a clear, unified vision of what responsible innovation is, what it requires in order to be effective, nor what it can accomplish.
The Virtual Institute for Responsible Innovation (VIRI)

The Virtual Institute for Responsible Innovation (VIRI) was created to accelerate the formation of a community of scholars and practitioners who, despite divides in geography and political culture, will create a common concept of responsible innovation for research, training and outreach – and in doing so contribute to the governance of emerging technologies under conditions dominated by high uncertainty, high stakes, and challenging questions of novelty.
Mission

VIRI’s mission in pursuit of this vision is to develop and disseminate a sophisticated conceptual and operational understanding of RI by facilitating collaborative research, training and outreach activities among a broad partnership of academic and non-academic institutions.
Activities

VIRI will:

  • perform interlinked empirical, reflexive and normative research in a collaborative and comparative mode to explore and develop key concepts in RI;
  • develop curricular material and support educational exchanges of graduate students, post-doctoral fellows, and faculty;
  •  create a dynamic online community to represent the breadth of the institute and its multi-lateral activities;
  •  disseminate outputs from across the institute through its own and partner channels and will encourage broad sharing of its research and educational findings.

VIRI will pursue these activities with founding academic partners in the US, the UK, the Netherlands, Germany, Denmark, Norway, Brazil and Canada.

I was a bit surprised to see Canada’s University of Waterloo rather than the University of Alberta (home of Canada’s National Institute of Nanotechnology)  as one of the partners.

Amid controversies, Australian government spends big bucks on Australian Institute for Nanoscience

Kim Carr, Australia’s Minister for Innovation, Industry, Science and Research, delivered  an extraordinary speech, by Canadian standard (ours tend to remarkable blandness), at the sod-turning event for the new Australian Institute for Nanoscience (AIN) due to open in May 2015. Before getting to the speech, here’s a bit more about the event from a July 24, 2013 news item on Global Times,

Australian government will deliver a fund for the new Australian Institute for Nanoscience ( AIN) which will open in May 2015 to boost its research of nanotechnology, Minister for Innovation, Industry, Science and Research Kim Carr confirmed in a statement after breaking the ground for the new facility at the University of Sydney on Wednesday.

The AIN project is a major new building combining research laboratories with teaching facilities to drive cross-disciplinary collaboration to develop nanomaterials and devices.

The July 24, 2013 Australian government media release about the AIN sod-turning provides more details about the government’s investment in the institute and its backing of nanoscience/nanotechnology research,

Senator Kim Carr said the Australian Government’s $40 million contribution, through the Education Investment Fund, to assist in the facility’s construction backs in Labor’s commitment to giving our researchers the tools they need to pursue world-leading work.

“Nanotechnology is a transformative force for manufacturing and is predicted to be worth $US3 trillion globally by 2020. Australia needs to stake a claim to our slice of that pie now, by building well-researched prototypes for the market. AIN will help make that happen and keep Australian research internationally competitive.”

Senator Carr said AIN will increase our national research capability by bringing together world-class nanoscience researchers across three main areas:

  • New medical diagnostics and therapies combining quantum technology with imaging and drug delivery and solutions such as a fully implantable bionic eye;
  • Faster, more secure and more efficient communications based on photonics and quantum science technologies; and
  • Revolutionary optical instrumentation to explore the frontiers of our universe, along with faster data processing technologies for the SKA.

I’m not sure where Carr got the “… worth $US3 trillion globally by 2020” number for nanotechnology’s impact on the global economy. More interesting to me, are these comments from Carr’s speech (you can find the entire speech here),

It is a great pleasure to share in the progress of the Australian Institute for Nanoscience here at Sydney University.

Three years have passed since I announced the funding for this facility:

$40 million from the Federal Government;

backed by $71 million from the university;

and a further $20 million from other sources, including the New South Wales government, the Australian National Fabrication Facility; the ARC’s CUDOS; the Australian Astronomical Observatory and Bandwidth Foundry International.

It was one of the many projects made possible by the Education Investment Fund – which, over three rounds, secured a total of $3.5 billion in new research infrastructure for a federal contribution of $1.5 billion.

This is an impressive return on investment.

At that time, this was the sort of research guaranteed to bring out the anti-science crowd.

There were beat-ups in the press, demonstrations in universities, and scare campaigns run on worksites. [emphasis mine]

It was as if the Enlightenment had never happened. It was as if nanoscience was some kind of global conspiracy to kill us all with sunscreen. [emphasis mine]

But I saw this project differently. And I put my views on the record at the time this investment was announced.

As I said back then:

“I don’t begin by saying “this is too strange” or “this is too hard”. I don’t begin by saying “no”.

I begin by asking, “what’s in it for Australia?” – “what’s in it for the people we serve?” – and “how can we make this work?”

The speech continues with a very optimistic view of all the economic benefits to be derived from an investment in nanoscience/nanotechnology.

Given the extreme lack of interest in Canada and its very odd (or perhaps it’s a harbinger of the future?) almost unknown National Institute of Nanotechnology (NINT), which exists on a NINT University of Alberta website and on a NINT National Research Council website, the “beat-ups in the press, etc.” provide a fascinating and contrasting socio-cultural perspective. The difference is perhaps due to a very active, both in Australia and internationally, Friends of the Earth group.

Friends of the Earth Australia campaigned long (years) and hard against nanosunscreens in a leadup to some rather disturbing survey findings in 2012 (my Feb. 9, 2012 posting) where some 13% of Australians, first reported as 17%,  didn’t use any sunscreens whatsoever, due to their fear of ‘nanosunscreens’.

Kim Carr has been mentioned here before in an Aug. 26, 2011 posting which highlighted a study showing  Australians held positive (?) attitudes towards nanotechnology and those attitudes had gotten more positive over time. My guess, not having looked at the study, is that the study focussed on areas where people usually express positive attitudes (e. g. better health care with less invasive medical procedures) and not on environmental issues (e.g. nanosilver in your clothing washing off and ending up in the water supply).

I do love how elected officials, the world over, pick and choose their ‘facts’.

Pretty decent directory of Cdn. nanotech companies, organizations, and education programmes

The folks at the Nanowerk website have dug into their database of nanotechnology companies, education programmes, and more to create an overview of the Canadian nanotechnology scene, from the Jan. 29, 2013 news item (Note: A link has been removed),

Canada offers world-class R&D infrastructure, a highly skilled and educated workforce, a wide array of government funding programs in support of nanotechnologies, a growing number of companies involved in nanotechnologies, and government commitment to the responsible development and application of nanotechnologies.

In 2001, the National Institute for Nanotechnology (NINT) was established as Canada’s flagship nanotechnology institute; it is operated as a partnership between the National Research Council and the University of Alberta.

Currently, there are 90 companies in Canada involved in nanotechnology-related business activities.

In addition, there are 64 nanotechnology and nanoscience-related research and community organizations in Canada.

There are 15 academic nanotechnology degree programs in Canada.

The item proceeds to list a number of companies according to these classifications,

Nanomaterial Suppliers
Nanobiotechnology and Nanomedicine Companies
Nanotechnology Products, Applications & Instruments Companies
Nanotechnology Services & Intermediaries

Based on my information (and memory), this listing is in pretty good shape given that it’ s not managed, i.e., people submit information voluntarily and may or may not remember to update it. For example, the company now known as Vive Crop is listed as Vive Nano.  In the listing for ‘initiatives and networks in Canada with a nanotechnology focus’, the defunct NanoTech BC is listed but the currently active Nano Ontario is not.  Also, anyone who wants to locate a business or service in their province will have difficulty as the listings are alphabetical and the short description of the organization does not include location information.

All things considered, they’ve done a remarkably good job of gathering and presenting this information. Thank you to the folks at Nanowerk for this resource.

Speaking of resources, the item does mention Canada’s National Institute of Nanotechnology (NINT) which has undergone some big changes in the last few months. Their previous website  as part of the larger National Research Council (NRC) website has been archived and the new NINT website suggests a serious downsizing effort of some sort has occurred.  The ‘lean and mean’ NRC NINT website contrasts strongly with the more informative and alternative NINT website located on the larger University of Alberta website. As both NINTs boast the same executive director, Dr. Marie D’Iorio, it would seem to be the same organization albeit with two different sites that are not linked to each other. Perhaps this is a new version of Canada’s two solitudes, this time starring the University of Alberta and the National Research Council of Canada. On second thought, the situation may more closely echo that old song title, Torn between two lovers.

Changing of the guard at Canada’s National Institute of Nanotechnology

The executive director (Nils Petersen) has passed on (to the University of Alberta’s science faculty), l9ng live the executive director (Marie D’Iorio) of Canada’s National Institute of Nanotechnology (NINT), long may she reign. (I think Queen Elizabeth II’s Diamond Jubilee may be getting to me.) From the May 31, 2012 news release on Market Wire,

An expert in nano-electronics will lead Canada’s National Institute for Nanotechnology (NINT) into its second decade. The NINT governing council has named Dr. Marie D’Iorio as its new Executive Director. Trained as a physicist, Dr. D’Iorio’s expertise is in nano-electronics. She had been acting as NINT’s interim Director General since last year.

NINT is one of the National Research Council Institutes,

During her time as acting Director General of NINT, Dr. D’Iorio led the strategic planning process for NINT’s second decade. The resulting plan aims to increase industrial collaboration and re-organize the Institute’s research and development activities into four application areas, including energy generation storage and hybrid nano-scale electronics.

“Nanotechnology can help Canadian companies be more competitive and NINT is key to them finding the right applications for their sector,” said John R McDougall, President of the National Research Council of Canada. “Marie D’Iorio’s mission is to expand NINT’s engagement with Canadian industry and help them benefit from the potential of small tech.”

McDougall’s comments come on the heels of the recommendations by the panel reviewing  Canada’s R&D (research and development) funding (mentioned in my May 29, 2012 posting),

Recommendation 4: Transform the institutes of the National Research Council (NRC) into a constellation of large-scale, sectoral collaboration R&D centres involving business, the university sector and the provinces while transferring public policy-related research activity to the appropriate federal agencies. (p. E12 print version, p. 26 PDF, Innovation Canada: A Call to Action)

I wonder if the panel was looking at the NINT as a model for the National Research Council’s other institutes (from the May 31, 2012 news release),

The National Institute for Nanotechnology is Canada’s leading research and technology development organization working at the nano-scale. Founded in 2001, it is a joint initiative of the National Research Council of Canada, the University of Alberta, the Government of Alberta and the Government of Canada. Its mission is to transform nanoscience ideas into novel, sustainable nanotechnology solutions with socioeconomic benefits for Canada and Alberta.

Interestingly, the National Research Council’s (NRC) president, John McDougall, is from Alberta, as is Prime Minister Stephen Harper,  (from the NRC’s McDougall biography webpage),

Mr. John R. McDougall, a leader in Canadian science and technology policy and innovation, was appointed as NRC’s President in April 2010.

Born and raised in Edmonton, Alberta and honoured as one of the province’s 50 most influential citizens, Mr. McDougall’s career spans many sectors, with a broad and far reaching range of accomplishments and roles to his credit.

Until recently, Mr. McDougall served as President and Chief Executive Officer of the Alberta Research Council (ARC), a position he has held for the past 12 years.

Edmonton (Alberta, Canada) toots its nanotechnology horn

I’m not sure what, if anything, occasioned the proclamation (from the May 31, 2012 news item on Nanowerk),

On the western edge of the University of Alberta’s main campus lies the National Institute for Nanotechnology (NINT), one of the world’s most advanced research facilities and Canada’s quietest laboratory space.

“NINT is helping us all to better understand the emerging science of nanotechnology. As the only centre of its kind in Canada, it puts us in a leadership position. Being located at the University of Alberta creates great synergies,” says Mike Wo, EEDC [Edmonton Economic Development Corporation] executive director of economic growth and development.

I wish there was a little more information about why Canada’s NINT is considered one of the world’s most advanced research facilities. The NINT website’s most recent news release (as of this morning, May 31, 2012)  is datedJuly 17, 2009.

I don’t receive or come across much information about NINT’s research efforts or facilities. The little information I have found (and it does not fully support the contention) comes from the University of Alberta or the University of Calgary. Is there more and where is it? If anyone knows, please do contact me either via the commenting facility for this blog or at nano@frogheart.ca.

DRUPA and 3-D printing

The world’s biggest trade fair for the printing industry, DRUPA; International Trade Fair for prepress, premedia, printing, book binding, print finishing and paper converting,  is being held May 3 – 16th, 2012 in Düsseldorf, Germany. This year’s presentations include one about paper loudspeakers (from the May 2, 2012 news item on Nanowerk),

At drupa print media fair, … , the Institute for Print and Media Technology of Chemnitz University of Technology (pmTUC) presents new research results, which truly make you prick up your ears: Loudspeakers that have been printed with flexography on standard paper. The R&D group of Prof. Dr. Arved Hübler, head of pmTUC, is co-exhibitor of press manufacturer Windmöller & Hölscher KG (Lengerich) …

I’m always curious as to just how practical these things might be and, oddly, they don’t offer an audio file or video file demonstrating the loudspeaker’s effectiveness although there is this video about pmTUC’s participation in DRUPA 2012,

Here’s what they have to say about the paper loudspeakers (from the news item),

The printed paper loudspeaker is connected to an audio amplifier like a conventional loudspeaker. “Frequency response and hence sound quality are very good and the paper is surprisingly loud. Just the bass of the paper-based loudspeaker is a bit weak”, explains Dr. Georg Schmidt, senior researcher at pmTUC. The thin loudspeakers, which are printed in the laboratories of pmTUC, contain several layers of a conductive organic polymer and a piezoactive layer. According to project assistant Maxi Bellmann the loudspeakers are astonishingly robust and can be produced in a very cheap way as mass printing methods are used. The bottom side of the paper loudspeaker provides unused space on which coloured messages can be printed.

Prof. Hübler expects a broad range of new applications: The paper loudspeakers could, for instance, be integrated into common print products. As such, they offer an enormous potential for the advertising segment. “In addition, sound wallpapers and purely technical applications, e.g., distance sensors, are possible, because the papers are also active in the ultrasound range”, says Hübler and adds: “As printing allows for different formats and forms, there is the possibility to influence the generated sound waves.”

As I understand it, Hübler is predicting that the graphic arts/printing industry is going to change from adding ink to paper to something entirely different, printed electronics. There’s more about that in the May 2, 2012 news item.

This reminded me that in 2008, Xerox announced a major investment in Canada’s National Institute of Nanotechnology (NINT). Details were pretty fuzzy (from the Xerox June [?] 2008  press release),

In Canada’s first major public-private nanotechnology research partnership, the Xerox Research Centre of Canada (XRCC), NRC National Institute for Nanotechnology (NINT) and Government of Alberta will provide approximately $4.5 million for research and development of materials-based nanotechnology over the next three years.

The three partners will invest funds, human resources, and available infrastructures to create a research program and teams focused on developing commercially successful nanotechnology-based discoveries. Personnel from NINT and XRCC will collaborate on research projects at NINT in Edmonton, Alberta, and at XRCC in Mississauga, Ontario.

The funds will contribute to the hiring of eight to 10 scientists who will investigate materials-based nanotechnologies, including document- and display-related technologies. The research program, co-managed by XRCC and NINT, will allow access to Xerox’s experience in successfully commercializing technology to facilitate the market application of resulting inventions.

“This level of public and private sector partnership helps fuel the type of innovation that will keep Alberta, and Canada as a whole, strong and competitive in an increasingly global, knowledge-based economy,” said Doug Horner, minister for Advanced Education and Technology, Government of Alberta. “The investments from the Government of Alberta, Xerox and NINT will build a world-class nanotechnology research program that embraces the spirit of innovation, but also that of commercialization.”

XRCC was established in 1974 to develop the materials used by Xerox Corp. globally, and began nanotechnology-enabled research efforts several years ago. It has already developed successfully commercial materials, including ‘EA Toner’, a unique technology for making more cost-effective and environmentally efficient toner for printers. XRCC will now be able to expand its nanotechnology efforts.

While  a toner is mentioned, it’s not clear what inventions and materials they are trying to create either in the Xerox press release or Canada’s National Research Council (NINT is an NRC institute) June 8, 2018 news release. In any event, I cannot find any other announcements about this Xexox/NINT research project, which has now ended.

Walking on eggshells at the University of Alberta

It’s Friday, April 13, 2012 and I wanted a little fun in my headline so Zhi Li and his colleagues in the Mitlin Group at the University of Alberta are not walking on eggshells. They are, instead, carbonizing them as a means of increasing the amount of electrical energy that can be stored as Michael Berger explains in his April 12, 2012 article, Converting eggshell membranes into a high-performance electrode material for supercapacitors (links have been removed from the following excerpt),

Today’s commercial supercapacitors – which are mostly electric double layer capacitors (EDLC) – store energy in two closely spaced layers with opposing charges and offer fast charge/discharge rates and the ability to sustain millions of cycles. Researchers have come up with various electrode materials to improve the performance of supercapacitors, focussing mostly on porous carbon due to its high surface areas, tunable structures, good conductivities, and low cost. In recent years, this has increasingly included research on various carbon nanomaterials such as carbon nanotubes, carbon nano-onions, or graphene.

“An ideal supercapacitor is one with both high energy density and high power density,” Zhi Li, a post doc researcher in David Mitlin’s group at the University of Alberta, explains to Nanowerk. …

In new work recently published in Advanced Energy Materials (“Carbonized Chicken Eggshell Membranes with 3D Architectures as High-Performance Electrode Materials for Supercapacitors”), first-authored by Li, researchers have demonstrated that a common daily waste – the eggshell membrane – can be converted into a high-performance carbon material for supercapacitors.

“Considering over 1000 billion eggs are consumed per year globally, and that 30–40 mg finished carbon is derivable from one egg, the eggshell membrane is indeed a reliable and sustainable resource for clean energy storage,” says Li.

“The most exciting finding, for me, is that the amazing nature-made architecture of chicken eggshell membrane is critical to its performance as electrode materials after carbonization,” notes Li. “Why? The carbonized eggshell membrane is a real ‘integrated system’ composed of interwoven carbon fibers with diameter from 50 nm to 2 µm where the big fibers and tiny fibers are naturally connected together.”

As a consequence of their architecture,

… carbonized eggshell membrane can work at high current loading. That means capacitors based on it can be charged and discharged faster than capacitor based on traditional carbons.

You can find out more about the Mitlin Group here and you can find the article, “Carbonized Chicken Eggshell Membranes with 3D Architectures as High-Performance Electrode Materials for Supercapacitors,” here but it is behind a paywall. By the way, Dr. David Mitlin, group leader, is also a principal investigator at Canada’s National Institute of Technology.
