Nanocellulose fibres, pineapples, bananas, and cars

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.

“The properties of these plastics are incredible,” Leão said, “They are light, but very strong — 30 per cent lighter and 3-to-4 times stronger. We believe that a lot of car parts, including dashboards, bumpers, side panels, will be made of nano-sized fruit fibers in the future. For one thing, they will help reduce the weight of cars and that will improve fuel economy.”

Besides weight reduction, nano-cellulose reinforced plastics have mechanical advantages over conventional automotive plastics, Leão added. These include greater resistance to damage from heat, spilled gasoline, water, and oxygen. With automobile manufacturers already testing nano-cellulose-reinforced plastics, with promising results, he predicted they would be used within two years. [emphasis mine]

This sounds very similar to the work being done by FPInnovations with wood cellulose in Québec and in BC. I did post an interview with Dr. Richard Berry, Aug. 27, 2010 (http://www.frogheart.ca/?p=1922) where he described and discussed what FPInnovations calls  nanocrystalline cellulose. Coincidentally, Mark MacLachlan is giving a talk about nanocrystalline cellulose  at the Café Scientifique meeting in Vancouver tomorrow, March 29, 2011. Check my March 25, 2011 posting for more details.

Here’s a description of cellulose and the process by which the Brazilian researchers are extracting nanocellulose fibres (from the news item),

Cellulose is the main material that makes up the wood in trees and other parts of plants. Its ordinary-size fibers have been used for centuries to make paper, extracted from wood that is ground up and processed. In more recent years, scientists have discovered that intensive processing of wood releases ultra-small, or “nano” cellulose fibers, so tiny that 50,000 could fit inside across the width of a single strand of human hair. Like fibers made from glass, carbon, and other materials, nano-cellulose fibers can be added to raw material used to make plastics, producing reinforced plastics that are stronger and more durable.

Leão said that pineapple leaves and stems, rather than wood, may be the most promising source for nano-cellulose. He is with Sao Paulo State University in Sao Paulo, Brazil. Another is curaua, a plant related to pineapple that is cultivated in South America. Other good sources include bananas; coir fibers found in coconut shells; typha, or “cattails;” sisal fibers produced from the agave plant; and fique, another plant related to pineapples.

To prepare the nano-fibers, the scientists insert the leaves and stems of pineapples or other plants into a device similar to a pressure cooker. They then add certain chemicals to the plants and heat the mixture over several cycles, producing a fine material that resembles talcum powder. The process is costly, but it takes just one pound of nano-cellulose to produce 100 pounds of super-strong, lightweight plastic, the scientists said.

Since the Brazilian researchers are claiming that they will be introducing nanocellulose fibres into plastics within two years, I wonder if that has accelerated  the timeframe for applications (coatings, films, and textiles according to Dr. Berry) from FPInnovations and their nanocrystalline cellulose?

Nano magazine; quantum tamers; insight into Intel; science publicity hounds

I found a new magazine, nano: The Magazine for Small Science,  this morning (thanks to Andy Miah). There’s an eclectic range of material some of which you can access  for free here.  I’m particularly interested in the ‘Nano’ versus nano article by Andrew Carruthers as it’s all about marketing and branding and how nanotechnology branding should not be left to marketing communications departments in various businesses. He uses Apple’s iPod Nano and Tata’s Nano Car as two examples of businesses that used the word nano to brand their products. I understand that neither product is considered truly nano-based which makes the examples rather telling since they are branding exercises that could be described as purely ‘fantasy’.

Carruthers does mention ‘Silver Nano’ products (which are nano-based) marketed by Samsung but there is no comparison of the marketing strategies or even a discussion of the difference between ‘fantasy’ and genuine nano products. That said, I have no idea what his constraints were with regard to word count.

Carruthers states the main issue this way,

Like so many areas of research, nanotechnology can be discussed quite easily with people who understand it, but can effortlessly mutate into a perfect nightmare when explaining it to people who do not. At some time or another, many of us will have been placed in a position where it was necessary to explain our professions and areas of research to people who may not understand them. On many occasions, such people seem keen yet are completely dumbfounded by colourful explanations. There is a sense of dismay [emphasis mine] as they and others ‘misinterpret’ descriptions, ask seemingly unrelated questions, and generally find endeavours at explanation incomprehensible and bewildering. In the main, people are quite genuinely either oblivious to nanotechnology, or have a decidedly skewed notion of ‘what it does’. This chasm within public understanding can be quite easily filled by other means, and the real difficulty is when that chasm becomes filled by marketing communications, rather than fact.

I don’t agree with him about having a “… sense of dismay …”  when people misunderstand or misinterpret information as I think those interactions provide useful data for the person who’s doing the explaining. Sometimes a ‘wrong’ question points you in a completely direction because it wasn’t the question that was wrong, it was you.

In my opinion,  marketing communication and pop culture are for most people the top purveyors of science information, like it or not. The challenge is finding a way to get your own messages out there and heard by using some of the same strategies or even incorporating some of the ‘noxious’ marketing communication messages. I’m not sure whether Carruthers would agree with me or not but, given the tone of his article, I think not. You can read the article for yourself here.

Quantum Tamers; Revealing our weird and wired future is a documentary being presented October 17, 2009 at the Quantum to Cosmos (Q2C) festival in Waterloo, Canada. From the Azonano news item,

The documentary brings together a stellar line-up of quantum experts to explore promising future technologies involving super quantum computers, ultra secure quantum codes to safeguard our communications, and even teleportation.

Although quantum principles are not fully understood, quantum technologies are already responsible for many advances in technology we already use including lasers and their many applications, magnetic resonance imaging (MRIs), modern micro circuitry, plus CDs and DVDs.

Since the January 2009 announcement, by Paul Otellini, Intel CEO, that Intel would be investing $7B US to retool three  plants for the manufacture if 32 nanometre chips, I’ve been interested in Intel’s progress. This morning I found an article by Ellen McGirt on Fast Company which details Intel’s latest reinvention. I was intrigued to note that the $7B US investment was mentioned without a single hint that it’s a nanotechnology initiative.  From page 5 of the article,

When he [Otellini] made the unusual decision to travel to Washington, D.C., early this year to announce his $7 billion bet on U.S. manufacturing, “no one knew where the bottom was [in the economy], and there was a lot of uncertainty,” he recalls. The business case for U.S.-based facilities may not have been clear to others, but to Otellini, it’s right out of the Intel playbook: If the company controls manufacturing, it can control quality. “Now, we’re going to be a generation ahead.” He had another motive, too: “I wanted to get the attention of the government and to send a message to other companies that Intel was investing in the United States at a time of great uncertainty, and that we should reinvest together in the infrastructure of the country.” If this was a considered effort to improve Intel’s standing for future infrastructure projects, it’s not one other companies have picked up on. The response from other business leaders, he says, has been mute. “On the other hand, the President called and said that it was the only piece of good economic news since he’d been inaugurated,” Otellini says.

It’s an interesting article not least for how the writer portrays the various personalities.

I had a little wake-up call this morning on reading one of Andrew Maynard’s recent posts (here) where he is excoriating the publicity practices of some peer-reviewed journals. He mentions two articles that I have posted about here (the China deaths and the Canadian nano safety article from yesterday, October 15, 2009) and notes that the articles are being held back from public scrutiny for rather long periods while they are being made available to journalists and science writers with the effect that they are not receiving the scrutiny that they should. I had vaguely noticed that the first article was not available when I went looking and that the access information for the article I mentioned yesterday was vague but I didn’t make much of it. So, thanks Andrew for making me stop and think about it.
