Tiny, electrically conductive 3D-printed chair made from cellulose

Sweden’s Chalmers University of Technology researchers have just announced that they’ve printed a very small 3D chair with electrical properties using cellulose nanomaterials. From a June 17, 2015 news item on Nanowerk,

A group of researchers at Chalmers University of Technology have managed to print and dry three-dimensional objects made entirely by cellulose for the first time with the help of a 3D-bioprinter. They also added carbon nanotubes to create electrically conductive material. The effect is that cellulose and other raw material based on wood will be able to compete with fossil-based plastics and metals in the on-going additive manufacturing revolution, which started with the introduction of the 3D-printer.

Here’s the 3D-printed chair,

A June 17, 2015 Chalmers University of Technology press release (also on EurekAlert*), which originated the news item, describes the problem with printing from cellulose nanomaterials and how it was solved,

The difficulty using cellulose in additive manufacturing is that cellulose does not melt when heated. Therefore, the 3D printers and processes designed for printing plastics and metals cannot be used for materials like cellulose. The Chalmers researchers solved this problem by mixing cellulose nanofibrils in a hydrogel consisting of 95-99 percent water. The gel could then in turn be dispensed with high fidelity into the researchers’ 3D bioprinter, which was earlier used to produce scaffolds for growing cells, where the end application is patient-specific implants.

The next challenge was to dry the printed gel-like objects without them losing their three-dimensional shape.

“The drying process is critical,” Paul Gatenholm explains. “We have developed a process in which we freeze the objects and remove the water by different means as to control the shape of the dry objects. It is also possible to let the structure collapse in one direction, creating thin films.”

Furthermore, the cellulose gel was mixed with carbon nanotubes to create electrically conductive ink after drying. Carbon nanotubes conduct electricity, and another project at Wallenberg Wood Science Center aims at developing carbon nanotubes using wood.

Using the two gels together, one conductive and one non-conductive, and controlling the drying process, the researchers produced three-dimensional circuits, where the resolution increased significantly upon drying.

The two gels together provide a basis for the possible development of a wide range of products made by cellulose with in-built electric currents.

“Potential applications range from sensors integrated with packaging, to textiles that convert body heat to electricity, and wound dressings that can communicate with healthcare workers,” says Paul Gatenholm. “Our research group now moves on with the next challenge, to use all wood biopolymers, besides cellulose.”

The research findings are presented this week at the conference New Materials From Trees that takes place in Stockholm, Sweden, June 15-17 [2015].

The research team members are Ida Henriksson, Cristina de la Pena, Karl Håkansson, Volodymyr Kuzmenko and Paul Gatenholm at Chalmers University of Technology.

This research reminds me of another effort, a computer chip fashioned of cellulose nanofibrils (CNF) from the University of Wisconsin-Madison (mentioned in my May 27, 2015 post).

Nanocellulose markets report released

I don’t usually feature reports about market conditions as this information lies far outside my understanding. In other words, this post is not an endorsement. However, as I often feature information on nanocellulose and, less frequently, on efforts of commercialize it, this June 3, 2015 news item on Azonano is being added here to provide a more complete picture of the ‘nanocellulose scene’,

The report “Nanocellulose Market by Type (Cellulose nanocrystals [aka nanocellulose nanocrystals {NCC} or {CNC}], Cellulose nanofibrils [CNF], cellulose nanocomposites, and others), Application (Composites and Packaging, Paper and Paper Board, Biomedicine, Rheology Modifier, Flexible Electronics and Sensors, and Others), and Geography – Regional Trends & Forecast to 2019” published by MarketsandMarkets, Nanocellulose Market is projected to register a market size in terms of value of $250 Million by 2019, signifying firm annualized CAGR [compound annual growth rate] of 19% between 2014 and 2019.

Here’s more from the MarketsandMarkets undated news release,

Nanocellulose market is projected to register a market size in terms of value of $250 Million by 2019, signifying firm annualized CAGR of 19% between 2014 and 2019.

The report also identifies the driving and restraining factors for nanocellulose market with an analysis of drivers, restraints, opportunities, and strengths. The market is segmented and the value has been forecasted on the basis of important regions, such as Asia-Pacific, North America, Europe, and Rest of the World (RoW). Further, the market is segmented and the demand and value are forecasted on the basis of various key applications of nano cellulose, such as composites and packaging, paper and paper board, biomedicine, and other applications.

Rising demand for technological advancements in end-user industries is driving the nanocellulose market

The application of nano cellulose [sic for all instances] in the end-user industries is witnessing a revolutionary change mainly due to the commercial development of nano cellulose driven by the increasing petroleum prices and the high-energy intensity in the production of chemicals and synthetic polymers. Nano cellulose is being developed for the novel use in applications ranging from scaffolds in tissue engineering, artificial skin and cartilage, wound healing, and vessel substitutes to biodegradable food packaging.

The nano cellulose is considered as a viable alternative to the more expensive high tech materials such as carbon fibers and carbon nanotubes. Since nano cellulose is made from tightly packed array of needle like crystals, it becomes incredibly tough. This makes it perfect for building future body armors that are both strong and light. Nano cellulose is also being used to make ultra-absorbent aerogels, fuel efficient cars, biofuel, and many more. Nano cellulose has also been used as a tablet binder in the pharmaceutical companies, with gradual increasing applications in tampons, advance wound healing, and developing a vital role in existing healthcare products.

North America is projected to drive the highest demand for nano cellulose in its end-user industries by 2020 [sic]

North America is the largest market for nano cellulose currently and the same is expected to continue till 2019. This is because of continuous technological innovations, advancements in healthcare industry, and rising focus on biodegradable food packaging. Europe market is expected to register second highest growth rate after North America. The Asia-Pacific market is expected to show a steady growth rate but the market is currently lower than North America and Europe. The U.S. and European countries are projected to be the hub of nano cellulose manufacturing in the world and are projected to be the major consumers of nano cellulose by 2019.

Wood chip/computer chip, a cellulose nanofibril development

I imagine researchers at the University of Wisconsin-Madison and the US Department of Agriculture Forest Products Laboratory (FPL) are hoping they have managed to create a wood-based computer chip that can be commercialized in the near future. From a May 26, 2015 news item on ScienceDaily,

Portable electronics — typically made of non-renewable, non-biodegradable and potentially toxic materials — are discarded at an alarming rate in consumers’ pursuit of the next best electronic gadget.

In an effort to alleviate the environmental burden of electronic devices, a team of University of Wisconsin-Madison researchers has collaborated with researchers in the Madison-based U.S. Department of Agriculture Forest Products Laboratory (FPL) to develop a surprising solution: a semiconductor chip made almost entirely of wood.

The research team, led by UW-Madison electrical and computer engineering professor Zhenqiang “Jack” Ma, described the new device in a paper published today (May 26, 2015) by the journal Nature Communications. The paper demonstrates the feasibility of replacing the substrate, or support layer, of a computer chip, with cellulose nanofibril (CNF), a flexible, biodegradable material made from wood.

Here’s what the wood computer chip looks like,

A May 25, 2015 University of Wisconsin-Madison news release by John Steeno, which originated the news item, provides more details,

“The majority of material in a chip is support. We only use less than a couple of micrometers for everything else,” Ma says. “Now the chips are so safe you can put them in the forest and fungus will degrade it. They become as safe as fertilizer.”

Zhiyong Cai, project leader for an engineering composite science research group at FPL, has been developing sustainable nanomaterials since 2009.

“If you take a big tree and cut it down to the individual fiber, the most common product is paper. The dimension of the fiber is in the micron stage,” Cai says. “But what if we could break it down further to the nano scale? At that scale you can make this material, very strong and transparent CNF paper.”

Working with Shaoqin “Sarah” Gong, a UW-Madison professor of biomedical engineering, Cai’s group addressed two key barriers to using wood-derived materials in an electronics setting: surface smoothness and thermal expansion.

“You don’t want it to expand or shrink too much. Wood is a natural hydroscopic material and could attract moisture from the air and expand,” Cai says. “With an epoxy coating on the surface of the CNF, we solved both the surface smoothness and the moisture barrier.”

Gong and her students also have been studying bio-based polymers for more than a decade. CNF offers many benefits over current chip substrates, she says.

“The advantage of CNF over other polymers is that it’s a bio-based material and most other polymers are petroleum-based polymers. Bio-based materials are sustainable, bio-compatible and biodegradable,” Gong says. “And, compared to other polymers, CNF actually has a relatively low thermal expansion coefficient.”

The group’s work also demonstrates a more environmentally friendly process that showed performance similar to existing chips. The majority of today’s wireless devices use gallium arsenide-based microwave chips due to their superior high-frequency operation and power handling capabilities. However, gallium arsenide can be environmentally toxic, particularly in the massive quantities of discarded wireless electronics.

Yei Hwan Jung, a graduate student in electrical and computer engineering and a co-author of the paper, says the new process greatly reduces the use of such expensive and potentially toxic material.

“I’ve made 1,500 gallium arsenide transistors in a 5-by-6 millimeter chip. Typically for a microwave chip that size, there are only eight to 40 transistors. The rest of the area is just wasted,” he says. “We take our design and put it on CNF using deterministic assembly technique, then we can put it wherever we want and make a completely functional circuit with performance comparable to existing chips.”

While the biodegradability of these materials will have a positive impact on the environment, Ma says the flexibility of the technology can lead to widespread adoption of these electronic chips.

“Mass-producing current semiconductor chips is so cheap, and it may take time for the industry to adapt to our design,” he says. “But flexible electronics are the future, and we think we’re going to be well ahead of the curve.”

SAPPI to locate cellulose nanofibril facility in the Netherlands

SAPPI (formerly South African Pulp and Paper Industries) has announced it will build a nanocellulose facility in the Netherlands. From a March 11, 2015 news item on Nanowerk,

Sappi Limited, a leading global producer of dissolving wood pulp and graphics, speciality and packaging papers, is pleased to announce that it will build a pilot-scale plant for low-cost Cellulose NanoFibrils (nanocellulose) production at the Brightlands Chemelot Campus in Sittard-Geleen in the Netherlands. The pilot plant is expected to be operational within nine months.

A March 11, 2015 SAPPI media release (also on PR Newswire), which originated the news item, provides more detail about SAPPI’s nanocellulose business plans and the proposed pilot plant,

Commenting on the decision, Andrea Rossi, Group Head Technology, Sappi Limited, explained that the pilot plant will help with Sappi’s move into new adjacent business fields based on renewable raw materials. Sappi’s strategy includes seeking growth opportunities by producing innovative performance materials from renewable resources. The raw material for the pilot plant would be supplied from any of Sappi’s Saiccor, Ngodwana and Cloquet dissolving wood pulp plants. The pilot plant is the precursor for Sappi to consider the construction of a commercial CNF plant.

He goes on to say “the pilot plant will test the manufacturing of dry re-dispersible Cellulose NanoFibrils (CNF) using the proprietary technology developed by Sappi and Edinburgh Napier University. The location of the pilot plant at Brightlands Chemelot Campus provides Sappi with easy access to multiple partners with whom Sappi will seek to co-develop products that will incorporate CNF across a large variety of product applications to optimise performance and to create unique characteristics for these products.

The CNF produced by Sappi will have unique morphology, specifically modified for either hydrophobic or hydrophilic applications. Products produced using Sappi’s CNF will be optimally suitable for conversion in lighter and stronger fibre-reinforced composites and plastics, in food and pharmaceutical applications, and in rheology modifiers as well as in barrier and other paper and coating applications.

Speaking on behalf of Brightlands Chemelot Campus, the CEO Bert Kip said “We’re proud that a globally leading company like Sappi has chosen our campus for their new facility. The initiative perfectly fits with our focus area on bio-based materials and our new pilot plant infrastructure.”

In December 2014, Sappi and Edinburgh Napier University announced the results of their 3 year project to find a low cost energy-saving process that would allow Sappi to produce the nanocellulose on a commercially viable basis – and importantly without producing large volumes of chemical waste water associated with existing techniques. At the time, Professor Rob English, who led the research with his Edinburgh Napier colleague, Dr. Rhodri Williams, said “What is significant about our process is the use of unique chemistry, which has allowed us to very easily break down the wood pulp fibers into nanocellulose. There is no expensive chemistry required and, most significantly, the chemicals used can be easily recycled and reused without generating large quantities of waste water.

Math Jennekens, R&D Director at Sappi Europe who is the project coordinator and will oversee the pilot plant, said “We are very excited to be able to move from a bench top environment into real-world production. Our targeted run-rate will be 8 tons per annum. We will produce a dry powder that can be easily redispersed in water. The nanocellulose is unmodified which makes it easier to combine with other materials. The product will be used to build partnerships to test the application of our nanocellulose across the widest range of uses.”

He went on to thank the Government of the Province of Limburg in the Netherlands for their significant support and financial contribution towards the establishment of the pilot plant.

This business with a pilot production plant reminds me of CelluForce which has a cellulose nanocrystal (CNC) or, as it’s also known, nanocellulose crystal (NCC) production plant located in Windsor, Québec. They too announced a production plant which opened to fanfare in January 2012. in my Oct. 3, 2013 post (scroll down about 60% of the way) I noted that production had stopped in August 2013 due to a growing stockpile. As of March 11, 2015, I was not able to find any updates about the stockpile on the CelluForce website. The most recent CelluForce information I’ve been able to find is in a Feb. 19, 2015 posting (scroll down about 40% of the way).

Doubling paper strength with nanofibrils; a nanocellulose story

A June 3, 2014 Cerealus news release on PR Newswire announces a successful commercial trial for a new nanoscale process making paper stronger,

Cerealus, working with the University of Maine Process Development Center continues to be a leader in innovative technologies for Paper and Forestry research. Utilizing Cerealus’ unique starch encapsulation technology and UMaine’s proprietary developments, the collaborative effort enabled a novel bio-based cellulose nanofibrils (CNF) process to be used in paper and paperboard manufacturing at significantly higher levels than previously possible to develop high strength, lightweight and lower cost paper and paperboard.

The latest commercial trial doubled cellulose Nanofibril utilization in paper with the patent pending starch encapsulation technology, marketed as Cerenano™. This project confirms the promise of nanotechnology to deliver dramatic improvement in sheet density, porosity, surface quality and Z-direction strength (internal bond). Paper mills can expect:

  •     Tighter sheet
  •     More uniform surface
  •     Better printability
  •     Reduced opacity
  •     Reduced energy requirements

The collaborative private/public partnership has significantly improved the economic prospects for deploying nanotechnology in paper, wood and forestry products. A recent report estimates the current addressable market for nano cellulose at $500 million for North America.

Mike Bilodeau, Director of the UMaine Process Development Center underscored the commercial scalability of this project by saying, “This technology represents a significant break-through in the ability to leverage the unique properties of cellulose nanofibrils in paper and paperboard products.”

Tony Jabar, CEO and founder of Cerealus goes on to say, “Cerealus takes great pride in taking a lead role to create cutting edge nanocellulose technology. Successful paper makers appreciate innovation as a key to sustained profitability in the challenging paper making sector of our economy. This new development is our third generation technology and demonstrates the value of our collaboration with the University of Maine Process Development Center.”

Cerenano™ is a high performance additive that enables efficient loading of high levels of starch thus creating strong internal bond strength. The successful commercial trial demonstrated positive economic benefits and commercial scalability. The likely next phase in product development will be size press applications.

The University of Maine is working with several private companies and federal agencies to accelerate the commercialization of cellulose nanofibrils. This effort has significant implications to the health of National Forests and private timberland, as well as strategic and economic impacts to the domestic Forest Products Industry.

You can find Cerealus here and Cerenano™ page here where there’s a link to a 50 pp. presentation on Cerenano. From the presentation,

Cellulose Nanofibrils (CNF)
The Renewable Nanomaterial

• CNF can be made from any plant matter.
# Process uses a series of mechanical refining steps.
# Resulting material is FDA compliant and compatible with any aqueous system. CNF is cellulose.

• Not to be confused with Cellulose NanoCrystals (CNC)
# Produced using more expensive strong acid hydrolysis process.

It’s the first time I’ve stumbled across a comparison of any kind between CNC (also known as NCC, nanocrystalline cellulose) and CNF and I find it quite instructive.

Sounds like fracking to me: research into unconventional hydrocarbon production at Texas A&M University

A July 29, 2013 news item on Nanowerk features a Flotek Industries-sponsored research initiative at Texas A&M University,

Flotek Industries, Inc. announced today sponsorship of applied research at Texas A&M University to investigate the impact of nanotechnology on oil and natural gas production in emerging, unconventional resource plays.

“With the acceleration of activity in oil and gas producing shales, a better understanding of the impact of various completion chemistries on tight formations with low porosity and permeability will be key to developing optimal completion techniques in the future,” said John Chisholm, Flotek’s Chairman, President and Chief Executive Officer. “While we know Flotek’s Complex nano-Fluid chemistries have been successful in enhancing production in tight resource formations, we believe a more complete understanding of the interaction between our chemistries and geologic formations as well as a more precise comprehension of the physical properties and impact of our nanofluids in the completion process will significantly enhance the efficacy of the unconventional hydrocarbon completion process. This research continues our relationship with Texas A&M where we also are conducting research into acidizing applications in Enhanced Oil Recovery.”

The words ‘unconventional’ and ‘shale’ in the context of oil and gas production suggest fracking to me. For anyone who’s unfamiliar with the practice, here’s an excerpt from a good description in a June 27, 2013 news item on the BBC (British Broadcasting Corporation) website,

What is fracking?

Fracking is the process of drilling down into the earth before a high-pressure water mixture is directed at the rock to release the gas inside. Water, sand and chemicals are injected into the rock at high pressure which allows the gas to flow out to the head of the well.

The process is carried out vertically or, more commonly, by drilling horizontally to the rock layer. The process can create new pathways to release gas or can be used to extend existing channels.

Why is it controversial?

The extensive use of fracking in the US, where it has revolutionised the energy industry, has prompted environmental concerns.

The first is that fracking uses huge amounts of water that must be transported to the fracking site, at significant environmental cost. The second is the worry that potentially carcinogenic chemicals used may escape and contaminate groundwater around the fracking site. The industry suggests pollution incidents are the results of bad practice, rather than an inherently risky technique.

The July 29, 2013 Flotek Industries news release (on PRNewswire’s heraldonline.com website) which originated the news item provides more details about the research initiative,

Specifically, the research will focus its investigation on the oil recovery potential of complex nanofluids and select surfactants under subsurface pressure and temperature conditions of liquids-rich shales.

Dr. I. Yucel Akkutlu, Associate Professor of Petroleum Engineering in the Harold Vance Department of Petroleum Engineering at Texas A&M University will serve as the principal investigator for the project. Dr. Akkutlu received his Masters and PhD in Petroleum Engineering from the University of Southern California. He has over a decade of postgraduate theoretical and experimental research experience in unconventional oil and gas recovery, enhanced oil recovery and reactive flow and transport in heterogeneous porous media. He has recently participated in industry-sponsored research on resource shales including analysis of microscopic data to better understand fluid storage and transport properties of organic-rich shales.

“As unconventional resource opportunities continue to grow in importance to hydrocarbon production, understanding ways to maximize recovery will be key to improving the efficacy of these projects,” said Dr. Akkutlu. “The key to enhancing recovery will be to best understand robust, new technologies and their impact on the completion process. Research into complex nanofluid chemistries to understand the physical properties and formation interactions will play an integral role in the future of completion design to optimize recovery from unconventional hydrocarbon resources.”

There was a little surprise (for me) on the website’s Our Company webpage,

Flotek’s vision is to be the premier energy services company focused on best-in class technology, cutting-edge innovation and exceptional customer service all standing in the support of our never-ending commitment to provide superior returns for our stakeholders. Flotek Industries Inc., is a diversified global supplier of drilling-and production-related products and services to the energy and mining industries. Flotek is headquartered in Houston, Texas and its common shares are traded on the New York Stock Exchange market under the stock ticker symbol, “FTK.” FLOTEK was originally incorporated under the laws of the Province of British Columbia on May 17, 1985. [emphasis mine] On October 23, 2001, we approved a change in our corporate domicile to the state of Delaware and a reverse stock split of 120 to 1. On October 31, 2001, we completed a reverse merger with CESI Chemical, Inc. (“CESI”). …

I wasn’t expecting the British Columbia (Canadian province where I live) connection.

Moving on to the nanotechnology connection, there’s this about the nano-fluid technology they use currently on the company’s homepage,

You say nanocrystalline cellulose, I say cellulose nanocrystals; CelluForce at Japan conference and at UK conference

In reading the Oct. 14, 2012 news release from CelluForce about its presence at conferences in Japan and in the UK, I was interested to note the terminology being used,

CelluForce, the world leader in the commercial development of NanoCrystalline Cellulose (NCC), also referred to as Cellulose Nanocrystals (CNC),[emphases mine] is participating in two  upcoming industry conferences:  the ‘Nanocellulose Summit 2012’ in Kyoto, Japan on October 15, 2012, and ‘Investing in Cellulose 2012’, in London, UK, on November 5, 2012.

All of the materials from Canadian companies and not-for-profits have used the term nanocrystalline cellulose (NCC) exclusively, until now. I gather there’ve been some international discussions regarding terminology and that the term cellulose nanocrystals (CNC) is, at the least, a synonym if not the preferred term.

Here’s more about the conference in Japan (from the CelluForce news release),

The 209th Symposium on Sustainable Humanosphere: Nanocellulose Summit 2012’ welcomes the world’s top scientists and large research project leaders involved with nanocellulose to present on each country’s current status and prospects concerning nanocellulose research and industrialization.

What:                  CelluForce – What do we do?

When:                 Monday, October 15, 2012, 4 p.m. JST

Where:                 Kyoto Terrsa Venue, Shinmachi Kujo Minami-ku,
Kyoto, Japan (Kyoto Citizen’s Amenity Plaza)

I found out a little more about the conference Dr. Richard Berry will be attending on the Nanocellulose Summit 2012 webpage on the Kyoto University website,

The world’s top scientists and large research project leaders involved with nanocellulose (cellulose nanofiber (CNF) [sic] and cellulose nanocrystal (CNC or NCC) ) brought together. They will talk about each country’s current status and prospects concerning nanocellulose research and industrialization.

You can find more details, including the agenda, on the conference webpage.

Here’s more about the investment-oriented conference taking place in the UK,

In its second edition, ‘Investing in Cellulose 2012’ is a global conference on specialty cellulose, organized by CelCo. The company focuses primarily on the specialty cellulose business including the organization of cellulose training courses as well as advisory and consultancy to the industry.

What:                  Nanocrystalline technologies: Bringing Innovation to the Market

When:                 Monday, November 5, 2012, 2:30 p.m. BST

Where:                The Royal Horseguards Hotel, 2 Whitehall Court Whitehall, London SW1A 2EJ, United Kingdom

I have found an ‘Investing in Cellulose 2012‘ conference webpage (of sorts) on the CelCo website (Note: I have removed some of the formatting),

Based on the success of 2011 specialty cellulose conference and encouraged by a 92% return intention response we are pleased to announce that Investing in Cellulose -2012 Conference will take place in London on November 5th.

A cocktail will kick off the event the preceding night and close around 18:00 of November 5th.

The most I could find out about the UK conference organizer is that  Celco Cellulose Consulting is a Swiss company founded by two partners.

Paper and Fibre Research Institute holds nanocellulose party/seminar

My ears always prick up when I come across a nanocellulose story and this Sept. 26, 2012 news item on Nanowerk features a nanocellulose seminar hosted by the Paper and Fibre Institute (PFI) in Norway (Note: I have removed a link),

PFI has the pleasure to organize the 4th research seminar about cellulose and their nanomaterials. The seminar will take place at PFI in Norway, on November 14-15, 2012. This will be a follow-up of the successful seminars in Trondheim 2006, 2008, 2010. The seminar offers an excellent scientific program, including topics which reflect the most recent advances from basic research to practical applications.

During the last years it has been considerable interest in cellulose nanofibrils [emphasis mine] due to the wide range of potential areas of application. This includes replacement for plastics, reinforcement of composite materials, boosting paper properties, barrier material in packaging and bio-medical applications.

As per the term I highlighted, cellulose nanofibrils, KarenS very kindly dropped by my Aug. 2, 2012 posting on nanocellulose research to explain some of the terminology that gets tossed around,

From my understanding, nanocrystaline cellulose (NCC), cellulose nanocrystals (CNC), cellulose whiskers (CW) and cellulose nanowhiskers (CNW) are all the same stuff: cylindrical rods of crystalline cellulose (diameter: 5-10 nm; length: 20-1000 nm). Cellulose nanofibers or nanofibrils (CNF), on the contrary, are less crystalline and are in the form of long fibers (diameter: 20-50 nm; length: up to several micrometers).

There is still a lot of confusion on the nomenclature of cellulose nanoparticles, but nice explanations (and pictures!) are given here (and also in other papers from the same [TAPPI 2012 in Montréal] conference):


Thank you KarenS, I really appreciate the clarification and the link to additional information.

Back to the main event, I went to the webpage for the 4th research seminar about cellulose and their nanomaterials and found a listing of the speakers,

Tsuguyuki Saito (University of Tokyo):  “Material Properties of TEMPO-Oxidized Cellulose Nanofibrils: In bulk and Individual Forms”
Lars Berglund (KTH): “Unexplored materials property space – does nanofibrillated cellulose provide new possibilities?”
Michel Schenker (Omya): “Toward Nano-fibrillated Pigmented Cellulose Composites”
Anette Hejnesson-Hulten (Eka):  “Chemically Pretreated  MFC – Process, Manufacturing and Application”
Kriistina Oksman (Luleå Univ.of Techn): “Nanocelluloses extracted from  bio residues and their use in composites”
J.M. Lagaron (CSIC): “Nanocellulose as a reinforcing material in packaging films”
Tomas Larsson (Innventia): “Determining the specific surface area of NFC by CP/MAS 13C-NMR”
Tekla Tammelin, (VTT): “Dense NFC films with several opportunities for additional functionalities”
Kristin Syverud (PFI): “A biocompatibility study of microfibrillated cellulose”
Øyvind Gregersen (NTNU): “The effect of microfibrillated cellulose on the pressability and paper properties of TMP and ground calcium carbonate (GCC) based sheets”
Gary Chinga Carrasco (PFI): “Characterization of the fibrillation degree of various MFC materials and its implication on critical properties”
Marianne Lenes (PFI): “MFC as barrier material – possibilities and challenges”
Laura Alexandrescu (NTNU): “MFC filters for environmental particle filtration”
Per Stenius (NTNU): “Nanofibrils – do they fulfill the promises?”

Dag Høvik (Research Council of Norway): “Strategic research programmes within Nanotechnology and Advanced Materials in Norway, 2002-2021”.

Interestingly given our work in this field, there don’t seem to be any Canadians on the speaker list.  I imagine that this is largely due to the fact that they have healthy and active research community in Norway and this is not really an international affair.

Speakers will include Michal Lipson, professor of electrical and computer engineering, who will talk about manipulating light on a chip; and Jordan Katine, of Hitachi Global Storage Technologies and former Cornell postdoctoral associate, who will describe promising methods for making nanoscale magnetic devices.

The event’s keynote speaker will be William Brinkman, director of the Office of Science in the U.S. Department of Energy, who will address “Whither Nanoscience?”

Over the years, thanks in part to CNF, Cornell has helped “nanotechnology” become a household word: In 1997, a Cornell student used electron beam lithography to etch a red blood cell-sized guitar onto a silicon chip, a feat that garnered worldwide attention.

Cornell and CNF have stayed on the leading edge of nanoscale science. For example, in the last year, a low-pressure chemical vapor deposition machine for making graphene and carbon nanotubes was purchased through a grant, said Donald Tennant, CNF director of operations.

More than 700 researchers use CNF every year, and about half come from outside Cornell. A key goal of CNF is to have a low-overhead, open-access operating model and to level the playing field for researchers with limited resources, Tennant said.

You can find out more about the July 19, 2012 CNF event here. As for an opening address titled, Whither nanoscience? Doesn’t the word ‘whither’ give the address an old-fashioned flavour, something from the 19th century or perhaps from the bible (Whither thou goest, I will go [Ruth to Naomi])?

Meanwhile, on  July 20, 2012 there will be a special media briefing by Cornell and Stanford University (California) nanoscience researchers, from the July 13, 2012 news item on the Nanotechnology Now website,

On Friday, July 20, from 10 to 11 a.m. [EST], a special panel of nantechnology researchers will gather at Cornell University and explore the future of nanoscience during an interactive conversation with members of the media – both on site in Ithaca and online from anywhere in the world via WebEx technology.

Joining journalists for the discussion will be:

  • Juan Hinestroza, an associate professor fiber science, directs the Textiles Nanotechnology Laboratory at Cornell’s College of Human Ecology. His research on understanding fundamental phenomena at the nanoscale that are relevant to fiber and polymer science, has led to breakthrough “multifunctional fibers” that can hold or change color, conduct and sense micro-electrical currents, and selectively filter toxic gasses.
  •  ….

Media members are invited to take part, in person or online. To do so, please RSVP to John Carberry in Cornell’s Press Relations Office at 607-255-5353 or johncarberry@cornell.edu.

I last mentioned Juan Hinestroza in connection with work done by his students at Cornell University with textiles that give protection from malaria in a May 15, 2012 posting.
