Richard Berry (CelluForce) wins TAPPI’s first technical award in the nanotechnology division

Another day, another award for Dr. Richard Berry, as per this May 22, 2014 news item on Nanowerk (Note: A link has been removed),

Dr. Richard Berry of CelluForce has been named the first recipient of TAPPI’s International Nanotechnology Division’s Technical Award. This award recognizes outstanding accomplishments or contributions which have advanced the responsible and sustainable production and use of renewable nanomaterials. Dr. Berry will be presented with this award at TAPPI’s 2014 International Conference on Nanotechnology for Renewable Materials to be held June 23-26, 2014 in Vancouver, British Columbia.

Currently Vice-President and Chief Technology Officer for CelluForce, Berry has had a storied career (from the news item),

Prior to moving to CelluForce in 2011 he was Principal Scientist and leader of the nanotechnology initiative at FPInnovations. … He’s received many awards including the Nano-industry award from Nano Québec for his exceptional contribution to the development of cellulose nanocrystals, the Purvis Memorial Award and he’s been named one of Canada’s Clean 50 honourees. The initiatives Dr. Berry has spearheaded in recent years have allowed Canada to position itself as a world leader in the development of the new nanotechnology industry. This work was recognised through the 2012 NSERC Synergy award for innovation given to McGill University, FPInnovations, ArboraNano, and CelluForce .. .

I notice that the news item uses the term cellulose nanocrystals (CNC) rather than nanocrystalline cellulose (NCC). Perhaps this means someone will put me out of my misery soon and declare one term or other the winner.

As for the reference to Canada as a “a world leader in the development of the new nanotechnology industry,” that seems a little grandiose and odd. To my knowledge, no one refers to a ‘nanotechnology industry’. I believe the writer is trying say that Canada is a leader in the production of CNC. I wonder if they’ve (CelluForce) dealt with their stockpile first mentioned here in an Oct. 3, 2013 posting and again in an April 10, 2014 posting about the US Dept. of Agriculture’s workshop on commercializing cellulose nanomaterials. Should anyone know of the stockpile’s status at this time, please do let me know.

Here’s a link to the 2014 TAPPI Nanotechnology conference website here. and an interview here (Aug. 27, 2010)  where Dr. Berry very kindly answered my questions about what was then called, indisputably, nanocrystalline cellulose.

SurFunCell project merges nanotechnology and renewable resources (cellulose) to create new materials

Given the current Canadian interest in forest-based cellulose research (ArboraNano; Canadian Forest NanoProducts Network and  CelluForce), this Jan. 11, 2013 news item on Nanowerk seems à propos (Note: A link has been removed),

EU-funded [European Union] scientists are bringing two of the most important fields of research together to develop novel multifunctional materials.

European scientists are merging renewable resources with nanotechnology with EU funding of the ‘Surface functionalisation of cellulose matrices using cellulose embedded nanoparticles’ (Surfuncell) project.

This Jan. 7, 2013 article (on the Cordis website) which originated the news item, provides more details about cellulose and the SurFunCell project,

Cellulose is a polysaccharide, a long-chain sugar that is the main constituent of plant cell walls. Investigators are creating new composite materials (consisting of more than one individual material) composed of nano-scaled polysaccharide layers with embedded nanoparticles. The new class of high-value bio-based materials with tailored functions will be applicable to separation technology, medical devices, sensors and electronic systems.

Surfuncell is focused on modifying the surface of cellulose-based materials with polysaccharide derivatives and nanoparticles. Aside from using renewable materials, the project employs surface modification rather than the conventional practice of using nanoparticles as fillers in a bulk matrix. Scientists are creating demonstrators in the fields of pulp and paper, cellulosic yarns, cellulose films and filter membranes.

Scientists have created numerous nanoparticles and cellulose derivatives that are the source of new materials being produced in pilot tests. Among these are antimicrobial fibres for textiles and separation membranes with reduced clogging behaviour.

The subsequent project phase will focus on implementing pilot plant production of cellophane foils with enhanced barrier properties and of ultraviolet (UV)-protected paper surfaces. Surfuncell is merging nanotechnology and the use of renewable resources to develop novel multifunctional products in a sustainable way.

There was some excitement last year when a CNC (the term cellulose nanocrystals seems to be gaining over nanocrystalline cellulose [NCC]) pilot plant was opened in Wisconsin (July 27, 2012 posting), the official opening of the CelluForce plant in Québec (Jan. 30, 2012 posting), and in 2011, there was the announcement of a pilot plant to be opened in Alberta (July 5, 2011 posting).

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.

Buckypaper and nanocrystalline cellulose; two different paths to the same ends?

Buckypaper interests me largely because of its name (along with Buckyballs and Buckytubes [usually called carbon nanotubes]). I believe the names are derived from Buckminsterfullerenes a form of carbon engineered (it can be found in nature) in the labs at Rice University. From the Wikipedia essay on Buckminsterfullerenes,

Buckminsterfullerene is a spherical fullerene molecule with the formula C60. It was first prepared in 1985 by Harold Kroto, James Heath, Sean O’Brien, Robert Curl and Richard Smalley at Rice University.  Kroto, Curl, and Smalley were awarded the 1996 Nobel Prize in Chemistry for their roles in the discovery of buckminsterfullerene and the related class of molecules, the fullerenes. The name is an homage to Richard Buckminster Fuller, whose geodesic domes it resembles. Buckminsterfullerene was the first fullerene molecule discovered and it is also the most common in terms of natural occurrence, as it can be found in small quantities in soot.

Buckypaper is a main focus at the High Performance Materials Institute at the Florida State University, which has just *released a promotional video (according to the Oct. 3, 2011 news item on Nanowerk). Here’s the video,

It reminds me a little of the video for Nokia’s Morph concept, which was released a few years back. I haven’t heard any substantive news about that project although there are the occasional updates. For example, the Morph was originally described it as a phone and then they changed it to the Morph concept. I’d love to see a prototype one of these days. (There’s more about the Morph and its incarnations in my Sept. 29, 2010 posting.)

The descriptions for applications using Buckypaper reminded me of nanocrystalline cellulose as I’ve seen some of the same claims made for that substance. I’m hoping to hear about the new plant in Windsor, Québec which is supposed to be opening this fall. From the ArboraNano new projects page,

Currently, Canada has an 18- to 24-month global lead in the commercial production of NCC as a 1 ton/day demonstration plant located in Windsor, Quebec enters the final phases of construction. Startup is planned for Fall 2011.

It’s good to see all these different research efforts and to reflect on the innovation being demonstrated.

ArboraNano focuses on NCC

I found this May 10, 2011 news item about AboraNano’s plan to launch nine new research and development (R&D) projects on Nanowerk and noted that seven of these projects are going to be focused on uses for nanocrystalline cellulose (NCC).

(I have covered the topic of NCC several times, most recently in an interview with Mark MacLachlan in an interview about his work at the University of British Columbia in my March 25, 2011 posting and before that in an interview with Dr. Richard Berry of FP Innovations in my August 27, 2010 posting.)

From the news item,

ArboraNano, a member of Canada’s Business-Led Networks of Centres of Excellence program, is pleased to announce the launch of nine new research and development (R&D) projects targeting innovative paper grades, improved foams and nanocomposite developments using forest nanomaterials. Seven of these projects will focus on the use of non-toxic and environmentally-friendly nanocrystalline cellulose (NCC). The projects are to be carried out over the next two years by industrial scientists and engineers from the pulp and paper, automotive, machinery and engineering sectors, as well as researchers from Canadian universities and Canadian research institutes.

ArboraNano’s contribution to these projects totals $3.35 million with matching contributions from industry and provincial organizations.

Here’s a brief overview of the types of projects being supported (from the news item),

Paper and packaging projects

Among the projects recently launched with pulp & paper partners, three will focus on creating “greener” paper grades, paperboards and coatings with performance properties that will compare favorably to existing products. …

Automotive projects

The goal of the two recently launched projects in the automotive industry is to develop performance-enhancing additives used in the manufacture of polyurethane foam and construction products particularly for load building in seat cushion foam. … [NOTE: Researchers in Brazil are working with nanocellulose fibres in pineapples and bananas to reinforce plastics for use in the automotive industry. March 28, 2011 posting]

Nanocomposite and nanofluids projects

The creation of novel nanocomposites is a key area of research for many of ArboraNano’s industrial partners. Two new projects aimed at supporting the development of nanocomposites have been launched. …

You can get a complete list of the new projects along with abstracts and the names of the principal investigators here.

Nanocrystalline cellulose interview with Dr. Richard Berry of FPInnovations

Nanocrystalline cellulose (NCC) is one of the most searched items on this blog so it seemed like a good idea to send some questions about it to a Canadian company, FPInnovations, that has been a leader in  its development.  [Edited for typo, July 7, 2011] Dr. Richard Berry, program manager for FPInnovations very kindly answered. First a little biographical information,

Dr. Richard Berry is the manager of the FPInnovations Chemical Pulping Program and he has been the leader of the nanotechnology initiative at FPInnovations for the last several years. Dr. Berry is a key contributor to ArboraNano. His scientific accomplishments include work on the elimination of chlorinated dioxins and the development of a variety of bleaching technologies. Dr. Berry has overseen the industrial application of his numerous inventions. He is the author of more than eighty peer-reviewed publications and patents. The prestigious 2009 Nano-industry award from NanoQuébec was given to him for his exceptional contribution to the development of Nanocrystalline Cellulose. The initiatives Dr. Berry has spearheaded in recent years have allowed Canada to position itself as a world leader in the development of this new nanotechnology industry.

Now for the  interview:

Q: In light of the new Domtar-FPInnovations plant [mentioned here in my July 16, 2010 posting] which is going to be built in Windsor, Québec, could you tell me a little about nanocrystalline cellulose (NCC). I have looked at your information sheet which notes that cellulose is: milled then hydrolyzed with the NCC separated and concentrated so it can be treated chemically for new uses.  In layperson’s terms, what’s cellulose?

A:         Cellulose is the most abundant polymer on earth and is the major constituent of all plants; cotton is 100% cellulose. Cellulose is made of chains of glucose molecules and these arrange into amorphous (soft) and crystalline (hard) regions. These structures provide flexibility and strength respectively to the fibres that are made of cellulose.

The hard crystalline regions are separated from the soft amorphous regions in the process that we are using which also causes the separation of the crystallites in the crystalline regions. These crystallites are nanocrystalline cellulose and have a needle shape approximately 200nm in length and 10 nm in diameter

Q: What does hydrolyze mean, in simple terms?

A:         Hydrolyze in this process means that we break the bonds between the glucose molecules. This reaction occurs far more rapidly in the soft amorphous regions of the cellulose structure leaving the hard crystalline regions largely intact

Q: After [Edited for grammar, July 7, 2011] all this processing, do you have nanocrystalline cellulose and how would you describe what nanocrystalline cellulose is?

A:         The process is to produce nanocrystalline cellulose but many of the processing steps are to ensure that the process is closed cycle and that the acid used is recovered and that the dissolved glucose can be separated to make energy, ethanol or higher value chemical products.

Nanocrystalline cellulose is the basic physical building block of plants which therefore have used nanotechnology for eons. The crystallites are the reinforcement elements providing strength in wood, paper and fibres.

Q: Does the process use up the entire log or are parts of it left over? What happens to any leftover bits?

A:         We are starting from the bleached chemical pulp which is, to a large extent, cellulose. The left over bits have actually been processed as part of the chemical pulp mill processes. The acid used is recovered and reused and the sugars are converted into other products; in the demonstration plant they will be converted into biogas.

Q: I understand you won’t want to give away any competitive advantages but could you describe at least partially the sort of chemical processing involved for these new applications?

A:         In some applications, there is no processing needed at all. In other applications, the formulation used allows the NCC to be effective. In further applications, surface modification is required to maximize the properties.

Q: Is the new plant (Domtar-FPInnovations) meant to be used for producing nanocrystalline cellulose particles for shipment elsewhere? Or will there be work on applications using the nanoparticles? If so, on which application(s) are you concentrating your efforts?

A:         The plant presently is for producing various grades of nanocrystalline cellulose for shipment elsewhere. The applications are being developed with partners in the new industry sectors that we are targeting. Amongst others, we have partners for applications in coatings, films and textiles.

Q: Is FPInnovations involved with the ArboraNano Centre of Excellence programme and its efforts to encourage NCC use in industries not usually associated with forest products? What might involvement entail?

A:         FPInnovations is one of the founding members and had a significant role in setting up ArboraNano.  Our involvement presently is as a supplier of NCC through our pilot plant in Pointe Claire and as members of both the Scientific Committee and Board of Arboranano.

Q: Assuming FPInnovations is attending the 2010 TAPPI [International Conference on Nanotechnology for the Forest Product Industry] in Finland, can you give me a preview of the company’s proposed presentation(s) at the conference?

A:         Representatives of FPInnovations will be at the conference but our involvement will be limited because much of the material we have developed is proprietary to ourselves and to the partners that we have. Our focus at this stage is commercial development.

Q: What kind of research is being done on possible health, safety and environment issues with regard to NCC?

A:         From the very beginning of our project, 20% of our funding has been spent on these issues. We are glad to say that the research has shown that NCC is in the category of “practically non toxic”, and mammalian studies done to assess inhalation, ingestion and dermal risk have all shown the material to be in the lowest category of risk. These results show that the size of a particle is not a determinant of its risk but as with chemicals it is the specific material that is critical in determining toxicity.

Q: Are there plans, at some point in the future, to list NCC on Charles McGovern’s Integrated Nano-Science Commodities Exchange or will your product be listed on some other commodities exchange?

A:         We do not view NCC at the moment as a commodity; it is a very specialized group of materials. We hope it will take a long time before it becomes a commodity.

Thank you very much Dr. Berry.

On a related matter, I was fortunate enough to receive a copy of the documentation that the Canadian federal government provided in response to Member of Parliament, Peter Julian’s (NDP), question about nanotechnology funding from 2005/6 – 2008/9. The response from Natural Resources Canada highlighted funding provided to FPInnovations in fiscal year 2007/8 of $2,308,000 and in fiscal year 2008/9,  a further, $3,2570,000 for a total of $5,565,000. Natural Resources Canada did not fund any nanotechnology research in 2005/6 or 2006/7.

One final note, former president and chief executive officer of FPInnovations, Ian de la Roche, PhD, will be the keynote speaker at the 10th Pacific Rim Bio-Based Composites Symposium Oct. 5-8, 2010 in Banff, Alberta.
