NanoCelluComp (nanocellulose composites) goes to JEC Composites Show and Conference in Paris (France)

NanoCelluComp (nanocellulose composites), a European Commission-funded project under the European Union’s 7th Framework Programme, which is entering its final stage (2011 – 2014) will make an appearance (Exhibition Stand D83) at the JEC 2014 Composites Show and Conferences in Paris (France), 11-13th March, 2014.

I  profileded NanoCelluComp in a March 7, 2013 posting where I included excerpts from the project’s 4th newsletter. The 5th (August 2013) newsletter is available here. There is also a project flyer (PDF), which provides some additional insight into why the project was developed and what NanoCellulComp was attempting to accomplish,

Food processing of vegetables produces billions of tonnes of fibrous waste. The cellulose fibres contained within this waste have superior structural properties that with ‘green’ chemistry can be put to much better use. Composites containing cellulose extracted from carrot waste have already been incorporated in lightweight products such as fishing rods and steering wheels.

This material – Curran – while exhibiting good structural properties, does not have the strength of glass or carbon fibre reinforced plastics (GFRP and CFRP) and is further disadvantaged due to limited processability.

The NanoCelluComp Process Improving on Curran through:

Liberating microfibrillated cellulose (nanocellulose) from vegetable waste streams utilising an aqueous based process (thus decreasing energy consumption, and avoiding volatile chemicals).
 Improving mechanical properties by the controlled alignment and cross linking of nanocellulose fibrils.
 Combining the resultant fibres with bio-based resins to produce a 100% bio-composite (thus decreasing use of petroleum-based products).
 Ensuring compatibility of the bio-composite with current manufacturing processes (e.g. injection moulding, hand lay-up).
 Investigating the sustainability of the above processes and materials, compared to existing materials, through a full life-cycle assessment (LCA) and identifying promising application fields.

Most of the ‘nanocellulose’ material that I’ve covered has been focused on derivations from forest products however there is one other team (that I know of) led by researcher Alcides Leão of Brazil examining the possible uses of nanocellulose derived from pineapples and bananas. On that note, my June 13, 2011 posting titled: Transcript of nanocellulose fibre podcast interview with Alcides Leão, Ph.D., from São Paulo State University and/or my March 28, 2011 posting titled: Nanocellulose fibres, pineapples, bananas, and cars may be of interest.

Brazil, Canada, and an innovation, science, and technology forum in Vancouver (Canada)

The Brazil-Canada Chamber of Commerce (BCCC) is presenting, in partnership with Simon Fraser University’s (SFU) Beedie School of Business, an all-morning forum on June 17, 2013. From the SFU Vancouver Events: June 14 – 21, 2013 announcement (Note: Links have been removed),

Brazil-Canada Business, Innovation, Science, and Technology Forum

Time: 8-11:30am

Place: Segal Graduate Business School, 500 Granville St.

Cost: $35-70, register online

Join us for a morning focused on Business Innovation and Science & Tecnology opportunities in the Brazilian economy. The opening speakers, Ambassador Sergio Florencio, Consul General and Dr. Jeremy Hall will provide an overview of the landscape in Brazil. The panel discussion includes industry leaders who have piloted extensive business in Brazil specifically in the agriculture, mining and infrastructure fields: Marcelo Sarkis, Heenan Blaikie; Ray Castelli, Weatherhaven and Rogerio Tippe, Javelin Partners. If you are interested in conducting business in Brazil and would like to understand more about the dynamics of the Brazilian economy and how businesses operate, please register now.

If the event is about business, innovation, science, and technology, it seems curious the only mentions of science and/or technology in the event description are confined to a few of the panelists’ interests in agriculture, mining, and whatever they mean by infrastructure.

Brazil is one of the BRICS (Brazil, Russia,India, China, and South Africa) countries and, from what I understand, this very loose coalition is eager to take a leadership position vis à vis science, technology, and innovation supplanting the dominance of the US, Japan, and the European Union.

In the early 1990s, I wrote a paper about science and technology transfer and noted that Brazil was entering a new period of development after years of the country’s science and technology efforts (scientists) being isolated from the rest of the world in a failed  attempt to create a powerhouse international enterprise.

Some 20 years later, the decision to join the rest of the science and technology world seems to have been successful. Brazil is set to host the 2014 World Cup for soccer (or, as most of the world calls it, football) and the summer Olympics in 2016. (Sports are often correlated with science and technology advances.) I don’t believe any other country has ever attempted to host two such large international sports events within two years of each other. That’s a pretty confident attitude.

There are two areas of science and technology research in Brazil that are of particular interest to me, brain research and the work on cellulose nanocrystals (CNC), also known as, nanocrystalline cellulose (NCC).

While the focus was on Miguel Nicolelis and Duke University (US), the recent announcement of brain-to-brain communication via the Internet featured a research facility in Brazil (from my Mar. 4, 2013 posting),

Miguel Nicolelis, a professor at Duke University, has been making international headlines lately with two brain projects. The first one about implanting a brain chip that allows rats to perceive infrared light was mentioned in my Feb. 15, 2013 posting. The latest project is a brain-to-brain (rats) communication project as per a Feb. 28, 2013 news release on *EurekAlert,

Researchers have electronically linked the brains of pairs of rats for the first time, enabling them to communicate directly to solve simple behavioral puzzles. A further test of this work successfully linked the brains of two animals thousands of miles apart—one in Durham, N.C., and one in Natal, Brazil.

The results of these projects suggest the future potential for linking multiple brains to form what the research team is calling an “organic computer,” which could allow sharing of motor and sensory information among groups of animals. The study was published Feb. 28, 2013, in the journal Scientific Reports.

“Our previous studies with brain-machine interfaces had convinced us that the rat brain was much more plastic than we had previously thought,” said Miguel Nicolelis, M.D., PhD, lead author of the publication and professor of neurobiology at Duke University School of Medicine. “In those experiments, the rat brain was able to adapt easily to accept input from devices outside the body and even learn how to process invisible infrared light generated by an artificial sensor. So, the question we asked was, ‘if the brain could assimilate signals from artificial sensors, could it also assimilate information input from sensors from a different body?’”

One of Nicolelis’s other goals is to have someone with quadriplegia kick the opening ball for the Brazil-hosted 2014 World Cup (Walk Again Project). From my Mar. 16, 2012 posting,

It is the exoskeleton described on the Walk Again Project home page that Nicolelis is hoping will enable a young Brazilian quadriplegic to deliver the opening kick for the 2014 World Cup (soccer/football) in Brazil.

Moving on to the other area of interest, CNC research , which in Canada is discussed in terms of the forestry industry (I’ve blogged about this extensively, the search term NCC should fetch most if not all of my postings on the topic), is taking a different tack in Brazil where the focus is on pineapple and banana fibres. My Mar. 28, 20111 posting (Nanocellulose fibres, pineapples, bananas, and cars) focuses on cellulose and plastic,

Brazilian researchers are working on ways to use nanocellulose fibres from various plants to reinforce plastics in the automotive industry. From the March 28, 2011 news item on Nanowerk,

Study leader Alcides Leão, Ph.D., said the fibers used to reinforce the new plastics may come from delicate fruits like bananas and pineapples, but they are super strong. Some of these so-called nano-cellulose fibers are almost as stiff as Kevlar, the renowned super-strong material used in armor and bulletproof vests. Unlike Kevlar and other traditional plastics, which are made from petroleum or natural gas, nano-cellulose fibers are completely renewable.

My second and, to date, only other posting (June 16, 2011) about the work in Brazil features a transcript of an interview with CNC researcher, Alcides Leão.

Finally, I have a few factoids which I will tie together, loosely, and try to show how they relate to this forum. First, São Paulo, Brazil hosts the world’s second oldest and one of its most important biennial visual arts events. (BTW, the next one, Bienal de São Paulo,  is in 2014.) Second, the recent Council of Canadian Academies assessment, State of Science and Technology in Canada, 2012, stated that Canada rates very highly in six areas, one of those areas being the Visual and Performing Arts. Admittedly Canada’s prominence in the visual and performing is fueled largely by efforts in Québec (as per the assessment), still, one would think there might be some value in trying to include that sector in this  forum and encourage the local visual and performing arts technology industry to make connections with the Brazilian industry.

Finally for those of you who have persisted, here’s the link to buy tickets for the June 17, 2012 forum.
