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.

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.

At the atto scale

Earlier this week, a team of Canadian scientists announced that they were able to observe a chemical bond as it broke. From the news item on physorg.com,

Scientists at the National Research Council of Canada (NRC) and the University of Ottawa (uOttawa) enjoyed a bird’s eye view of a chemical bond as it breaks.

The making and breaking of chemical bonds underlie the biochemical processes of life itself. A greater understanding of the quantum processes that lead to chemical reactions may lead to new strategies in the design and control of molecules — ultimately leading to scientific breakthroughs in health care and diagnostic medicine, quantum computing, nanotechnology, environmental science and energy.

The NRC-uOttawa team, led by Dr. David Villeneuve, achieved their feat using a technique developed several years ago at NRC in which an image was obtained of a single electron orbiting a molecule. In the current experiment, which is reported in the July 29th edition of Nature, scientists injected bromine gas into a vacuum chamber. There, an ultra brief ultraviolet light pulse caused the bromine molecules to separate into their individual atoms (a bromine molecule is composed of two bromine atoms).

A few femtoseconds later, an intense infrared laser pulse caused the molecule to emit an attosecond-duration X-ray burst that contained a snapshot of the atom’s position as the molecule fell apart and revealed how the electrons rearranged themselves.

The interference of the x-rays emitted by the two quantum states of the molecule was used to find the location of the atoms and to watch over a period of only 200 femtoseconds as it progressed from being a molecule to being two separate atoms. The experiment reached a precision below 500 zeptoseconds in clocking the emitted x-ray bursts. [emphases mine]

I’ve highlighted the units of measurement because they fascinate me in and of themselves. (I hadn’t encountered zeptos before although I have blogged about attoseconds,  May 13, 2009 posting).

Here are official designations starting with the nanoscale and dropping down to the smallest unit to date (from the US National Institute of Standards and Technology, Technology Services, Weights and Measures page),

nano, (n), meaning 10-9
pico, (p), meaning 10-12
femto, (f), meaning 10-15
atto, (a), meaning 10-18
zepto, (z), meaning 10-21
yocto, (y), meaning 10-24

If nano is the science of small, what will the others be?

Memristors and nuances in a classification tug-of-war; NRC of Canada insights; rapping scientists

Interestingly, there’s an item posted with today’s (April 8, 2010) date on the Nanowerk website from HP Labs reiterating the ‘memristor as a fourth circuit element’ concept that Forrest H Bennett has convincingly argued against first in his comments to my original posting (April 5, 2010) and, at greater length, in yesterday’s (April 7, 2010) interview.

Oddly, the item on Nanowerk, which I’m assuming is a news release from HP Labs as no author is listed, mostly regurgitates the HP Labs work on the memristor.

HP Labs researchers have discovered that the “memristor“ – a resistor with memory that represents the fourth basic circuit element in electrical engineering – has more capabilities than was previously thought. In addition to being useful in storage devices, the memristor can perform logic, enabling computation to one day be performed in chips where data is stored, rather than on a specialized central processing unit.

In fact, much of what’s mentioned in the news release and in the accompanying video was discussed in 2008 when they first published their work. The new excitement has been generated by a team at the University of Michigan (see April 5, 2010 posting), led by Dr. Wei Lu, who’ve proved that synapses in biological organisms behave like memristors. This means that the speculations that the HP Lab folks made in 2008 about hardware that learns are more likely.

As for the ‘fourth circuit element’ mentioned in the item, this brings me to classification schemes. These sorts of discussions can seem picayune to people who are not directly involved but classification schemes have a huge impact on how we think about the world around us and the ways in which we interact with it. For example, we think of the tomato and treat it as if it’s a vegetable when in fact, it’s a fruit. When was the last time you had some tomatoes and ice cream?

Whether the memristor is thought of as a ‘fourth circuit element’ (as per HP Labs and Dr. Leon Chua [as of 2003]) or a member of an ‘infinite periodic table of circuit elements’ (as per Forrest H Bennett) will have an impact on how memristors and other as yet unknown elements are investigated and understood.

As someone who doesn’t understand the particulars especially well, I find Forrest’s approach the more flexible one and therefore preferable. Classification schemes or models that are rigid both buckle as new information is added and tend to constrain it. For example, the Dewey decimal classification scheme used in most public libraries has been buckling under the pressure of adding new categories since the 1950s, at least. It’s the reason most academic libraries use the more flexible Library of Congress classification scheme, although that scheme has its problems too.

One final note, it seems that HP Labs is supporting the notion of a ‘fourth circuit element’ being added to the previous three (capacitors, inductors, and resistors) and they have the resources to distribute their preferred notion far and wide and repeatedly. Or as Forrest put it in one of his comments, “This “4th circuit element” business is marketing spin from HP …”

National Research Council of Canada Insights

In the wake of John McDougall’s appointment as the new president of the Canada’s National Research Council (NRC), Rob Annan over at the Don’t Leave Canada Behind blog has written a very important (if Canadian science policy interests you) piece about NRC.  Rob traces the organization from its beginnings.  From the posting,

The NRC was founded more than 90 years ago to advise the government on matters related to science and technology. It evolved into a federal research laboratory with the construction of the Sussex Dr. labs in the 1930s, and was the focus of Canada’s research efforts during WWII. Post-war, the NRC expanded and was a major source of Canadian research success, with notable achievements like the invention of the pacemaker, development of Canola and the crash position indicator.

From the 1950s through the 1970s, NRC’s success, growth, and increasing complexity led to the creation of spin-off organizations. Atomic research went to the Atomic Energy of Canada, defense research went to the Defense Research Board. Medical research funding went to the Medical Research Council, later the CIHR. Lastly, support for academic research was passed to NSERC.

All of these organizations have grown and prospered. The NRC? Not so much.

He goes on to trace developments to the present day,

The NRC has research institutes in every province in the country, from the Herzberg Institute of Astrophysics in BC to the Institute for Ocean Technology in Newfoundland. A total of 26 institutes across the country, covering all aspects of science and technology, and employing more than 4,000 people. It’s a broad effort and employs a lot of great scientists.

But since the 1980s, the NRC has been without a strong sense of self. Is it a basic research organization or an applied research organization? Does it exist to perform independent, government-sponsored research, or does it provide research services in support of the private sector? Does it perform early-stage research and then partner with industry, or is it a fee-for-service research organization? The answer is yes.

I encourage you to read his posting as there’s more to his history and analysis and he goes on to make some suggestions. Please don’t forget to read the comments which offer additional insights.

Dave Bruggeman (at Pasco Phronesis) also mentions Rob’s NRC posting in the context of explaining that the current US National Research Council differs greatly from the Canadian one and warns against assuming that organizations with similar names are the same. You can go read Dave’s description of the US NRC here. This is a timely reminder as the ‘reinventing technology assessment’ webcast that the Project on Emerging Nanotechnologies is hosting later this month features a speaker from the US National Research Council.

Rapping biologists and physicists

While browsing on Dave’s (Pasco Phronesis) blog, I found an item that features two videos of scientists rapping. The first comes from some physicists and the second comes from biologists. I agree with Dave that the biologists have the edge since they rap in front of a live audience although both videos are quite entertaining.

What happened to Canada’s National Insitute of Nanotechnology?

It’s been a while since I’ve visited Canada’s National Institute of Nanotechnology’s (NINT) website and since it’ s pretty slow on the news front these days I figured I’d check out their news releases. It wasn’t there! It’s  been absorbed into the National Research Council’s (NRC) site.

These things usually portend some sort of political shenanigans, which can range from internal NRC politics to federal policy mandates to funding issues, or some combination of them all. In NINT’s case, you can also include the provincial government (Alberta) as they were (and possibly still are) funding a significant portion of the institute’s budget.

The NINT information now available has been ‘branded’ by the NRC. It looks slick and seems a bit better organized than it was in some respects. One exception is in the area of media information. NINT media releases are now grouped with all of the NRC releases making NINT information harder to find. As well, it’s harder to find contact details for the NINT media relations/communications folks.

Taking into account the loss of the NanoBusiness Alliance in Toronto, Nanotech BC’s imperiled future, and NINT’s loss of its ‘brand’, the nanotechnology future is not looking so bright in Canada.

Science funding cuts in the Canadian 2009 budget

Lost in all the excitement over Genome Canada’s disappearance from the budget is the drop in funding allocations for all three national research councils, Natural Sciences and Engineering Research Council (NSERC), National Research Council (NRC), and I think they’re including the Canadian Institutes of Health Research (CIHR) as the third one even though the name isn’t quite right. You can read up on the situation here and notice how the other three institutions are hardly mentioned.

Interestingly there was a recent article (Sat., Jan. 24, 2009) in the Globe and Mail about health research in Canada and how a great many US researchers flocked up because their funding was being limited and cut off in the US. Two researchers interviewed for the article mentioned that they were seeing similar signs of a freeze or even loss of funds, as they’d experienced in the US, on the horizon here as they were having problems with funding requests. (As I recall, the focus was on stem cell research but it might have been something else too.)

I am concerned in a general sense although I’m not a big fan of all this genomic mapping. How does mapping the genome of any organism help? As far as I can tell, all they’ve done is identify characteristics but they don’t understand how any of it works together. (I’m going to see if I can find a quote from Denise Caruso about genes and mapping them. As I recall, it hasn’t really amounted to anything much.)

While I disagree with some of the emphasis, I’m still concerned that all the science funding is being pulled back at this time. The whole thing is in stark contrast to the Obama administration’s interest in revitalizing and strengthening research in the US by pumping additional funds.
