US White House establishes new initiatives to commercialize nanotechnology

As I’ve noted several times, there’s a strong push in the US to commercialize nanotechnology and May 20, 2015 was a banner day for the efforts. The US White House announced a series of new initiatives to speed commercialization efforts in a May 20, 2015 posting by Lloyd Whitman, Tom Kalil, and JJ Raynor,

Today, May 20 [2015], the National Economic Council and the Office of Science and Technology Policy held a forum at the White House to discuss opportunities to accelerate the commercialization of nanotechnology.

In recognition of the importance of nanotechnology R&D, representatives from companies, government agencies, colleges and universities, and non-profits are announcing a series of new and expanded public and private initiatives that complement the Administration’s efforts to accelerate the commercialization of nanotechnology and expand the nanotechnology workforce:

  • The Colleges of Nanoscale Science and Engineering at SUNY Polytechnic Institute in Albany, NY and the National Institute for Occupational Safety and Health are launching the Nano Health & Safety Consortium to advance research and guidance for occupational safety and health in the nanoelectronics and other nanomanufacturing industry settings.
  • Raytheon has brought together a group of representatives from the defense industry and the Department of Defense to identify collaborative opportunities to advance nanotechnology product development, manufacturing, and supply-chain support with a goal of helping the U.S. optimize development, foster innovation, and take more rapid advantage of new commercial nanotechnologies.
  • BASF Corporation is taking a new approach to finding solutions to nanomanufacturing challenges. In March, BASF launched a prize-based “NanoChallenge” designed to drive new levels of collaborative innovation in nanotechnology while connecting with potential partners to co-create solutions that address industry challenges.
  • OCSiAl is expanding the eligibility of its “iNanoComm” matching grant program that provides low-cost, single-walled carbon nanotubes to include more exploratory research proposals, especially proposals for projects that could result in the creation of startups and technology transfers.
  • The NanoBusiness Commercialization Association (NanoBCA) is partnering with Venture for America and working with the National Science Foundation (NSF) to promote entrepreneurship in nanotechnology.  Three companies (PEN, NanoMech, and SouthWest NanoTechnologies), are offering to support NSF’s Innovation Corps (I-Corps) program with mentorship for entrepreneurs-in-training and, along with three other companies (NanoViricides, mPhase Technologies, and Eikos), will partner with Venture for America to hire recent graduates into nanotechnology jobs, thereby strengthening new nanotech businesses while providing needed experience for future entrepreneurs.
  • TechConnect is establishing a Nano and Emerging Technologies Student Leaders Conference to bring together the leaders of nanotechnology student groups from across the country. The conference will highlight undergraduate research and connect students with venture capitalists, entrepreneurs, and industry leaders.  Five universities have already committed to participating, led by the University of Virginia Nano and Emerging Technologies Club.
  • Brewer Science, through its Global Intern Program, is providing more than 30 students from high schools, colleges, and graduate schools across the country with hands-on experience in a wide range of functions within the company.  Brewer Science plans to increase the number of its science and engineering interns by 50% next year and has committed to sharing best practices with other nanotechnology businesses interested in how internship programs can contribute to a small company’s success.
  • The National Institute of Standards and Technology’s Center for Nanoscale Science and Technology is expanding its partnership with the National Science Foundation to provide hands-on experience for students in NSF’s Advanced Technology Education program. The partnership will now run year-round and will include opportunities for students at Hudson Valley Community College and the University of the District of Columbia Community College.
  • Federal agencies participating in the NNI [US National Nanotechnology Initiative], supported by the National Nanotechnology Coordination Office [NNCO], are launching multiple new activities aimed at educating students and the public about nanotechnology, including image and video contests highlighting student research, a new webinar series focused on providing nanotechnology information for K-12 teachers, and a searchable web portal on nano.gov of nanoscale science and engineering resources for teachers and professors.

Interestingly, May 20, 2015 is also the day the NNCO held its second webinar for small- and medium-size businesses in the nanotechnology community. You can find out more about that webinar and future ones by following the links in my May 13, 2015 posting.

Since the US White House announcement, OCSiAl has issued a May 26, 2015 news release which provides a brief history and more details about its newly expanded NanoComm program,

OCSiAl launched the iNanoComm, which stands for the Integrated Nanotube Commercialization Award, program in February 2015 to help researchers lower the cost of their most promising R&D projects dedicated to SWCNT [single-walled carbon nanotube] applications. The first round received 33 applications from 28 university groups, including The Smalley-Curl Center for Nanoscale Science and Technology at Rice University and the Concordia Center for Composites at Concordia University [Canada] among others. [emphasis mine] The aim of iNanoComm is to stimulate universities and research organizations to develop innovative market products based on nano-augmented materials, also known as clean materials.

Now the program’s criteria are being broadened to enable greater private sector engagement in potential projects and the creation of partnerships in commercializing nanotechnology. The program will now support early stage commercialization efforts connected to university research in the form of start-ups, technology transfers, new businesses and university spinoffs to support the mass commercialization of SWCNT products and technologies.

The announcement of the program’s expansion took place at the 2015 Roundtable of the US NanoBusiness Commercialization Association (NanoBCA), the world’s first non-profit association focused on the commercialization of nanotechnologies. NanoBCA is dedicated to creating an environment that nurtures research and innovation in nanotechnology, promotes tech-transfer of nanotechnology from academia to industry, encourages private capital investments in nanotechnology companies, and helps its corporate members bring innovative nanotechnology products to market.

“Enhancing iNanoComm as a ‘start-up incubator’ is a concrete step in promoting single-wall carbon nanotube applications in the commercial world,” said Max Atanassov, CEO of OCSiAl USA. “It was the logical thing for us to do, now that high quality carbon nanotubes have become broadly available and are affordably priced to be used on a mass industrial scale.”

Vince Caprio, Executive Director of NanoBCA, added that “iNanoComm will make an important contribution to translating fundamental nanotechnology research into commercial products. By facilitating the formation of more start-ups, it will encourage more scientists to pursue their dreams and develop their ideas into commercially successful businesses.”

For more information on the program expansion and how it can reduce the cost of early stage research connected to university projects, visit the iNanoComm website at www.inanocomm.org or contact info@inanocomm.org.

Cosmetics giant, L’Oréal, to 3D print skin

L’Oréal, according to a May 19, 2015 BBC (British Broadcasting Corporation) online news item, has partnered with Organovo, a 3D bioprinting startup, to begin producing skin,

French cosmetics firm L’Oreal is teaming up with bio-engineering start-up Organovo to 3D-print human skin.

It said the printed skin would be used in product tests.

Organovo has already made headlines with claims that it can 3D-print a human liver but this is its first tie-up with the cosmetics industry.

Experts said the science might be legitimate but questioned why a beauty firm would want to print skin. [emphasis mine]

L’Oreal currently grows skin samples from tissues donated by plastic surgery patients. It produces more than 100,000, 0.5 sq cm skin samples per year and grows nine varieties across all ages and ethnicities.

Its statement explaining the advantage of printing skin, offered little detail: “Our partnership will not only bring about new advanced in vitro methods for evaluating product safety and performance, but the potential for where this new field of technology and research can take us is boundless.”

The beauty and cosmetics industry has a major interest in technology, especially anything to do with the skin. I’m curious as to what kind of an expert wouldn’t realize that cosmetics companies test products on skin and might like to have a ready supply. Still, I have to admit to surprise when I first (2006) started researching nanotechnology;  L’Oréal at one point was the sixth largest nanotechnology patent holder in the US (see my Nanotech Mysteries Wiki page: Marketers put the buy in nano [scroll down to Penetration subhead]). In 2008 L’Oréal company representatives were set for a discussion on their nanotechnology efforts and the precautionary principle, which was to be hosted by the Wilson Center’s Project for Emerging Nanotechnologies (PEN). The company cancelled at a rather interesting time as I had noted in my June 19, 2008 posting. (scroll down about 40% of the way until you see mention of Dr. Andrew Maynard).

Back to 3D printing technology and cosmetics giants, a May 5, 2015 Organovo/L’Oréal press release provides more detail about the deal,

L’Oreal USA, the largest subsidiary of the world’s leading beauty company, has announced a partnership with 3-D bioprinting company Organovo Holdings, Inc. (NYSE MKT: ONVO) (“Organovo”).  Developed between L’Oreal’s U.S.-based global Technology Incubator and Organovo, the collaboration will leverage Organovo’s proprietary NovoGen Bioprinting Platform and L’Oreal’s expertise in skin engineering to develop 3-D printed skin tissue for product evaluation and other areas of advanced research.

This partnership marks the first-ever application of Organovo’s groundbreaking technology within the beauty industry.

“We developed our technology incubator to uncover disruptive innovations across industries that have the potential to transform the beauty business,” said Guive Balooch, Global Vice President of L’Oreal’s Technology Incubator.  “Organovo has broken new ground with 3-D bioprinting, an area that complements L’Oreal’s pioneering work in the research and application of reconstructed skin for the past 30 years. Our partnership will not only bring about new advanced in vitro methods for evaluating product safety and performance, but the potential for where this new field of technology and research can take us is boundless.”

Organovo’s 3D bioprinting enables the reproducible, automated creation of living human tissues that mimic the form and function of native tissues in the body.

“We are excited to be partnering with L’Oreal, whose leadership in the beauty industry is rooted in scientific innovation and a deep commitment to research and development,” said Keith Murphy, Chairman and Chief Executive Officer at Organovo. “This partnership is a great next step to expand the applications of Organovo’s 3-D bioprinting technology and to create value for both L’Oreal and Organovo by building new breakthroughs in skin modeling.”

I don’t have much information about Organovo here, certainly nothing about the supposed liver (how did I miss that?), but there is a Dec. 26, 2012 posting about its deal with software giant, Autodesk.

Ink toner on paper: research into topographies

An April 14, 2015 news item on Nanowerk about pen (in this case, ink toner) and paper,

A team of Finnish scientists has found a new way to examine the ancient art of putting ink to paper in unprecedented 3-D detail. The technique could improve scientists’ understanding of how ink sticks to paper and ultimately lead to higher quality, less expensive and more environmentally-friendly printed products.

Using modern X-ray and laser-based technologies, the researchers created a nano-scale map of the varying thickness of toner ink on paper. They discovered that wood fibers protruding from the paper received relatively thin coatings of ink. In general, they also found the toner thickness was dictated mainly by the local changes in roughness, rather than the chemical variations caused by the paper’s uneven glossy finish.

“We believe that this gives new insight, especially on how the topography of paper impacts the ink setting or consolidation,” said Markko Myllys, an applied physicist at the University of Jyvaskyla in Finland. “This in turn helps us understand how glossy and non-glossy printed surfaces should be made.”

An April 14, 2016 American Institute of Physics (AIP) news release (also on EurekAlert) by Catherine Myers, which originated the news item, describes the research in more detail,

To achieve their detailed picture of ink thickness, the researchers first examined the underlying paper with X-ray microtomography, a smaller cousin of the CT scanning technology used in hospitals to produce images of the inside of the body.

To analyze the cyan ink layers, the researchers used two additional technologies: optical profilometry, which bounced a light beam off the surface of the ink to obtain a surface profile, and laser ablation, which zapped away controlled amounts of ink with a laser to determine the ink depth.

Although none of the imaging techniques are themselves new, the researchers were the first to combine all three to achieve a complete, high-resolution 3-D image of the intricate ink and paper microstructures.

The final images resemble a rugged mountain landscape, with the higher peaks generally showing thinner coatings of ink, and the valleys showing thicker pools.

The researchers found the typical ink layer was approximately 2.5 micrometers deep, about 1/40 the thickness of an average sheet of paper, but with relatively large spatial variations between the thickest and thinnest areas.

Knowing how topographical variations affect ink thickness will help the printing industry create more environmentally-friendly and less energy-demanding ink and optimize the size distribution of ink particles, Myllys said. It could also help the papermaking industry design more sustainable paper and packaging, for example from recycled components, while still maintaining the quality needed to make ink stick well. Additionally, the papermaking industry could use the findings to help decide how best to incorporate smart and novel features into paper, Myllys said.

The team believes the imaging methods they used can also be adapted to effectively analyze the thickness variations in other types of thin films, including those found in microelectronics, wear-resistant coatings and solar panels.

“This result can certainly be generalized, and that makes it actually quite interesting,” Myllys said. “Thickness variations of thin films are crucial in many applications, but the 3-D analysis has been very difficult or impossible until now.”

Crypton and NANO-TEX together at last

A Jan. 6, 2014 news item on Nanowerk notes that Crypton Fabrics has purchased NANO-TEX,

CRYPTON INC. has acquired NANO-TEX®, announced Randy Rubin, Chairman of The Crypton Companies. The privately held, 20-year-old Crypton Fabrics, based in Bloomfield Hills, Michigan, recently purchased NANO-TEX from private equity and venture capital investors; WL Ross and Co. LLC as major stockholders, in addition to Norwest Venture Partners, Masters Capital Nanotechnology Fund, Firelake Capital Management and Masters Capital Management.

NANO-TEX is a textile technology company whose performance finishes have enhanced leading consumer brands such as GAP, TARGET, MAIDENFORM, BASS PRO SHOPS, NORDSTROM, LAND’S END, FISHER-PRICE and many more.

The Jan. 6, 2014 Crypton (there has to be a Superman or inert gas enthusiast in that company) press release, which can be found on this page under this title: Silicon Valley to Motown, Performance Textile Leader Crypton Purchases Nano-Tex, explains why the NANO-TEX acquisition was so attractive and what it means to NANO-TEX’s major stockholders,

NANO‐TEX employs a proprietary nanotechnology approach to enhance textiles at the molecular level that provides permanent performance attributes such as stain and water resistance, moisture wicking, odor control, static elimination and wrinkle free properties. The end result is performance fabrics that maintain the original comfort, look and feel of the fabric and perform for the life of the product.

In 2013, NANO‐TEX technologies were on $280 million in branded finished products at retail worldwide.

Wilbur Ross, Jr., Chairman of WL Ross said, “We are extremely pleased by Crypton’s acquisition. This assures that NANO‐TEX will continue on a strong growth trajectory. Its expanding market reach and prominence will further enhance the competitiveness of WL Ross’s companies in the consumer and industrial fabrics industries, too; the goal that sparked our initial investment interest in NANO‐TEX eight years ago.”

It seems there was a specific product which attracted the Crypton team’s attention,

“This is a strategic acquisition as we extend our market share with apparel throughout the world. The intellectual properties and latest development, Aquapel®, a non‐fluorinated repellency treatment, is very exciting to our research team,” said Rubin.

There’s more about this product on the NANO-TEX Aquapel® page.

On a completely other note, at least one NANO-TEX product has silver in it according to a 2007 entry on the Consumer Products Inventory (Project on Emerging Nanotechnologies),

They Say:

“Nano-Tex™’s revolutionary technology fundamentally transforms fabric at the nano-level to dramatically improve your favorite everyday clothing.”



Potential Exposure Pathways:


How much we know:

Category 4 (Unsupported claim)

Additional Information:

Generic Product

Crypton too has silver in at least one product (from the INCASE Fabric Protection FAQs),

Q:  How does INCASE™ resist bacterial growth?
A: Silver Ion technology is used in INCASE to inhibit the growth of a broad spectrum of medically relevant microorganisms, including bacteria. Silver is one of nature’s original antimicrobials. Used thousands of years ago by Greeks in vessels to preserve water and wine, the natural benefits of silver have now been tapped to keep fabrics odor-free.

Cyrpton’s INCASE product uses sliver ions, which according to some research at Rice University (based in Texas, US), are more toxic than silver nanoparticles, from my July 13, 2012 posting,

He [Pedro Alvarez, George R. Brown Professor and chair of Rice’s Civil and Environmental Engineering Department] said the finding should shift the debate over the size, shape and coating of silver nanoparticles. [emphasis mine] “Of course they matter,” Alvarez said, “but only indirectly, as far as these variables affect the dissolution rate of the ions. The key determinant of toxicity is the silver ions. So the focus should be on mass-transfer processes and controlled-release mechanisms.”

Crypton’s About page strongly suggests an environmentally friendly and health conscious company (Note: Links have been removed),

Innovation. Industry leadership. A deep commitment to product excellence. These core elements are at the heart of the Crypton DNA – a labor of love that began in 1993 when founders Craig and Randy Rubin set out to create a new generation of stylish fabrics that were moisture-resistant and easy-to-clean, yet soft, comfortable and breathable.

From the basement of their Michigan home, a textile revolution was born.

Now based in West Bloomfield Michigan, with a green manufacturing facility in Kings Mountain, North Carolina, Crypton is the only textile solution in the world offering complete stain, moisture, mildew, bacteria and odor-resistant protection thanks to a patented process developed by some of the leading minds in the textile industry.

Early on, by offering a fabric – not a vinyl or plastic – that was capable of resisting stains, moisture, odors and bacteria, Crypton proved to be the perfect solution for the health care market. Following this initial success, Crypton solutions rapidly expanded into some of the finest restaurants, hotels, cruise ships around the world, as well as government complexes, schools and health care facilities.

Now trusted and relied on by over 90% of contract designers, there are more than 20,000 patterns of Crypton fabric available today. Crypton is the only fabric deemed a non-porous surface and can be disinfected when used in conjunction with our U.S. EPA-approved Crypton Disinfectant & Deodorizer.

From fabric, carpet, leather, wall and mattress to pet beds, home accessories, bags and luggage – our mission is to give customers more ways to live healthy, live beautifully and Live Clean®.

While there is no incontrovertible proof that silver nanoparticles and/or silver ions are a serious threat to the environment, it would be nice to see companies acknowledge some of the concerns.

Nanosilver—US Environmental Protection Agency (EPA) gets wrist slapped over nanosilver decision in textiles while Canadian Broadcasting Corporation (CBC) publishes article about nanosilver

I have two pieces about nanosilver today (Nov. 11 ,2013). The first concerns a Nov. 7, 2013 court ruling in favour of the Natural Resources Defense Council (NRDC) stating that the US Environmental Protection Agency (EPA) failed to follow its own rules when it accorded HeiQ Materials (a Swiss textile company) permission to market and sell its nanosilver-based antimicrobial fabric treatment in the US. From the NRDC’s Nov. 7, 2013 press release,

Court Ruling in NRDC’s Favor Should Limit Pesticide Nanosilver in Textiles

In a decision handed down today, the court said the EPA had improperly approved the use of nanosilver by one U.S. textile manufacturer [HeiQ Materials; headquarteed in Switzerland]. The court vacated the approval and sent it back to the agency for reevaluation. The lawsuit has been closely watched as a test case for the growing use of nanotechnology in consumer products.

“The court’s ruling puts us a step closer toward removing nanosilver from textiles,” said Mae Wu, an attorney in NRDC’s Health Program. “EPA shouldn’t have approved nanosilver in the first place. This is just one of a long line of decisions by the agency treating people and our environment as guinea pigs and laboratories for these untested pesticides.”

NRDC sued the U.S. Environmental Protection Agency in early 2012 to limit the use of nanosilver out of a concern for public health. Today the 9th U.S. Circuit Court of Appeals agreed with a key point NRDC raised: that the EPA didn’t follow its own rules for determining whether the pesticide’s use in products would be safe.

Beginning in December 2011, EPA approved the company HeiQ Materials to sell nanosilver used in fabrics for the next four years and required the company to provide data on toxicity for human health and aquatic organisms. In early 2012, NRDC filed a lawsuit against EPA seeking to block nanosilver’s use, contending, among several points, that the agency had ignored its own rules for determining the safety of nanosilver.

The key part of today’s Ninth Circuit ruling addressed EPA’s determination that there is no risk concern for toddlers exposed to nanosilver-treated textiles. The agency’s rules state that if there’s an aggregate exposure to the skin or through ingestion at or below a specific level, there is a risk of health concerns. But the Ninth Circuit found that the EPA had data showing that nanosilver was right at the level that should have triggered a finding of potential risk, but approved the pesticide anyway. That led to the Ninth Circuit vacating EPA’s approval and sending it back down to the agency for reevaluation.

Published in July 2013 (?), Nate Seltenrich’s article, Nanosilver: Weighing the Risks and BenefitsNanosilver: Weighing the Risks and Benefits, for the journal, Environmental Health Perspectives (EHP) [published with support from the National Institute of Environmental Health Sciences, National Institutes of Health, U.S. Department of Health and Human Services]) provides some insight into the court case and the issues,

It takes a special sort of case to spur attorneys into a debate over the drooling habits of toddlers. Yet that’s where lawyers from the Natural Resources Defense Council (NRDC), the U.S. Environmental Protection Agency (EPA), and Swiss chemicals company HeiQ found themselves in January 2013 as they debated in a federal appeals court the extent to which 1-year-olds and 3-year-olds chew, salivate, and swallow.1

At issue in the NRDC’s suit against the EPA, which is still awaiting ruling, was whether the agency was right in granting a conditional registration in December 2011 to a nanosilver-based antimicrobial fabric treatment manufactured by HeiQ.2 The EPA’s risk assessment was based in part on assumptions about exposure of 3-year-olds by sucking or chewing on nanosilver-laced textiles such as clothing, blankets, and pillowcases.

NRDC lawyer Catherine Rahm, however, begged to differ with the agency’s methods. In the January hearing, she argued that the agency record shows infants are more likely than any other subset of children to chew on fabrics that could contain the pesticide, and that if the agency were to recalculate its risk assessment based on the body weight of a 1-year-old, nanosilver concentrations in HeiQ’s product could result in potentially harmful exposures.

It’s an obscure but critical distinction as far as risk assessment goes. And given the implications for HeiQ and other companies looking to follow in its footsteps, the case has landed at the center of a prolonged conflict over the regulation of nanosilver and the growing deployment of this antimicrobial ingredient in a variety of commercial and consumer products.

Yet regardless of which side prevails in the case, the truth about nanosilver is not black and white. Even the loudest voices joining the NRDC’s call for strict regulation of nanosilver concede that context is key.

Seltenrich goes on to recount a little of the history of nanosilver and provide a brief a relatively balanced overview of the research. At the end of the article, he lists 37 reference documents and offers links, should you wish to research further. For anyone interested in HeiQ, here’s the company website.

The second nanosilver news item is from the CBC (Canadian Broadcasting Corporation( online. In an article by Evelyn Boychuk titled, Silver nanoparticle use spurs U.S. consumer database; Database tracks growing number of consumer goods containing nanomaterials, these nanoparticles are discussed within the context of a resuscitated Project on Emerging Nanotechnologies (PEN) Consumer Products Inventory (CPI), which was mentioned in my Oct. 28, 2013 posting titled: Rising from the dead: the inventory of nanotechnology-based consumer products. The articles offers an easy introduction to the topic and refers to a database of silver,nanotechnology in commercial products (complementary to the larger CPI).

Rising from the dead: the inventory of nanotechnology-based consumer products

The inventory of nanotechnology-based consumer products or the Consumer Products Inventory (CPI) is still cited in articles about nanotechnology and its pervasive use in consumer products despite the fact that the inventory was effectively rendered inactive (i.e., dead) in 2009 and that  it was a voluntary system with no oversight, meaning whoever made the submission to the inventory could make any claims they wanted. Now that it’s 2013, things are about to change according to an Oct. 28, 2013 news item on ScienceDaily,

As a resource for consumers, scientists, and policy makers, the Virginia Tech Center for Sustainable Nanotechnology (VTSuN) has joined the Woodrow Wilson International Center for Scholars to renew and expand the Nanotechnology Consumer Product Inventory, an important source of information about products using nanomaterials.

“We want people to appreciate the revolution, such as in electronics and medicine. But we also want them to be informed,” said Nina Quadros, a research scientist at Virginia Tech’s Institute for Critical Technology and Applied Science and associate director of VTSuN, who leads a team of Virginia Tech faculty members and students on this project. Todd Kuiken, senior program associate, and David Rajeski, director of the science and technology innovation program, lead this project at the Wilson Center.

The Oct. 28, 2013 Virginia Tech (Virginia Polytechnic Institute and State University) news release by Susan Trulove (which originated the news item),provides a brief history of the inventory and a description of its revivification,

The Wilson Center and the Project on Emerging Nanotechnology created the inventory in 2005. It grew from 54 to more than 1,000 products, many of which have come and gone. The inventory became the most frequently cited resource, showcasing the widespread applications of nanotechnology. However, in 2009, the project was no longer funded.

“I used it in publications and presentations when talking about all the ways nano is part of people’s lives in consumer products,” said Matthew Hull, who manages the Institute for Critical Technology and Applied Science’s investment portfolio in nanoscale science and engineering, which includes the Center for Sustainable Nanotechnology. “But the inventory was criticized by researchers, regulators, and manufacturers for the lack of scientific information available to support product claims.”

In a meeting with his friend, Andrew Maynard, director of the University of Michigan Risk Science Center, who had initiated the inventory when he was at the Wilson Center, Hull proposed leveraging Institute for Critical Technology and Applied Science and Center for Sustainable Nanotechnology resources to improve the inventory.

“My role was to ask ‘what if’ and [the Virginia Tech Center for Sustainable Nanotechnology] ran with it,” said Hull.

A partnership was formed and, with funding from the Virginia Tech institute, the Center for Sustainable Nanotechnology restructured the inventory to improve the reliability, functionality, and scientific credibility of the database.

“Specifically, we added scientific significance and usefulness by including qualitative and quantitative descriptors for the products and the nanomaterials contained in these products, such as size, concentration, and potential exposure routes,” said Quadros. For example, an intentional exposure route would be the way a medicine is administered. An unintentional exposure would be when a child chews on a toy that has been treated with silver nanoparticles that are used as an antimicrobial. The potential health effect of nanomaterials on children was Quadros doctoral research and she used the inventory to find products designed for children that use nanomaterials, such as plush toys.

“One of the best things about the new version of the inventory is the additional information and the ability to search by product type or the type of nanomaterial,” she said. “When researchers were first attempting to assess the potential environmental impacts of nanotechnology, one main challenge was understanding how these nanomaterials might end up in the environment in the first place. After searching the CPI and seeing the vast applications of nanotechnologies in consumer products it was easier to narrow down scenarios.”

For example, Quadros said many silver nanoparticles are used in clothing for antimicrobial protection, so we can infer that some silver nanoparticles may end up in wastewater treatment plants after clothes washing. This helped justify some of the research on the effects of silver nanoparticle in the biological wastewater treatment processes. Currently, the inventory lists 188 products under the ‘clothing’ category.”

This team also included published scientific data related to those products, where available, and developed a metric to assess the reliability of the data on each inventory entry.

The team interviewed more than 50 nanotechnology experts with more than 350 combined years of experience in nanotechnology, Quadros said. “Their answers provided valuable guidance to help us address diverse stakeholder needs.”

In addition, the site’s users can log in and add information based on their own expertise. “Anyone can suggest edits. The curator and reviewer will approve the edits, and then the new information will go live,” Quadros said.

“We’ve added the horsepower of [the Center for Sustainable Nanotechnology], but opened it by means of crowdsourcing to new information, such as refuting or supporting claims made about products,” Hull said.

“The goal of this work is to create a living, growing inventory for the exchange of accurate information on nano­enabled consumer products,” Quadros said. “Improved information sharing will allow citizens, manufacturers, scientists, policymakers, and others to better understand how nanotechnology is being used in the consumer marketplace,” she said.

As of October 2013,

The inventory currently lists more than 1,600 consumer products that claim to contain nanotechnology or have been found to contain nanomaterials.

Quadros will give a presentation about the inventory at the Sustainable Nanotechnology Organization conference in Santa Barbara on Nov. 3-5 and will present to the U.S. Environmental Protection Agency and the National Science Foundation in the spring.

Key collaborators at Virginia Tech are Sean McGinnis, an associate research professor in the materials science and engineering department; Linsey Marr, professor of civil and environmental engineering; her postdoc, Eric Vejerano, who was instrumental in development of product categories; and Michael Hochella, a university distinguished professor in the geosciences department and Virginia Tech Center for Sustainable Nanotechnology director.

The objective of this conference is to bring together scientific experts from academia, industry, and government agencies from around the world to present and discuss current research findings on the subject of nanotechnology and sustainability.

The conference program will address the critical aspects of sustainable nanotechnology such as life cycle assessment, green synthesis, green energy, industrial partnerships, environmental and biological fate, and the overall sustainability of engineered nanomaterials. In principle, this involves the fundamental/applied research on the chemistry of producing new green nanomaterials; eco-manufacturing processing of nanomaterials and products, using nanotechnology to benefit society, and examining possible harmful effects of nanotechnology.

The conference will also foster new collaborations between academic and industrial participants. This community of users, researchers and developers of engineered nanomaterials will provide a long-term, scientific assessment of where the science is for sustainable nano, where it should be heading, and what steps academics, government agencies and others can take now to reach targeted goals. In addition, the conference will serve as the platform to initiate the formation of the Sustainable Nanotechnology Organization (SNO), a non-profit, international professional society dedicated to advancing sustainable nanotechnology through education, research, and promotion of responsible development of nanotechnology.

Finally because I can resist no longer, especially so near to Hallowe’en, I guess you could call the ‘renewed’ CPI, a zombie CPI as it’s back from the dead and it needs brains,

Safe use of nanotechnology for environmental remediation June 5 – 7, 2013 conference/workshop

The inaugural conference/national workshop on the safe use of nanotechnology for environmental remediation is being held at Southeastern Louisiana University from June 5 – 7, 2013. A Southeastern Louisiana University May 23, 2013 news release provides more detail,

An increasing number of hazardous waste disposal sites are using nanotechnology and nanomaterials in their environmental remediation efforts, leaving open questions about the safety of such techniques.

“While applications and results of nano-enabled strategies for environmental remediation are promising, there is still the challenge of ensuring such applications are both safe and sustainable,” said conference organizer Ephraim Massawe. “The federal government has established different projects coordinated by different agencies, called signature initiatives. We plan on generating information supportive of some of these federal initiatives.”

The event, “Nano-4_Rem_Anseers2013: Applications of Nanotechnolgoy for Safe and Sustainable Environmental Remediations,” [sic] is a cooperative endeavor involving the university and agencies and institutions, such as the U.S. Environmental Protection Agency (EPA), the National Institute of Safety and Health (NIOSH) and the Occupational Safety and Health Administration (OSHA). The Louisiana Board of Regents is providing partial financial support.

The news release (which can also be viewed as a May 24, 2013 news item on Azonano) goes on to provide details about the keynote speakers,

Four keynote speakers are slated to address the three-day conference, which will be held on the Southeastern campus. Speakers and topics include:

— Patrick O’Shaughnessy, professor of occupational and environmental health in the Department of Civil and Environmental Engineering at the University of Iowa, “Nanosafety: Current Issues and Guidance;”
— Dongye Zhao, Huff endowed professor of environmental engineering at Auburn University: “Application of Stabilized Nanoparticles for in situ Remediation of Contaminated Soil and Groundwater;”
— Souhail Al-Abed of the EPA Office of Research and Development, National Risk Management Research Laboratory in Cincinnati: “Nanotechnology and the Environment: an Overview of Sustainable and Safe Applications in Site Remediation.”

In addition, a representative of the National Nanotechnology Coordinating Office will speak at the workshop.

Massawe had this to add about federal initiatives (from the news release),

Massawe said at least 30 EPA Superfund sites across the nation are currently using nanomaterials in remediation operations.

I have written about Nano-4_Rem_aNssERs2013: Applications of Nanotechnology for Safe and Sustainable Environmental Remediations before in a Nov. 7, 2012 posting when it was first announced and where you will find links to some of my other posts on nanotechnology and environmental remediation. Rather than add links to yet a few my other postings on the topic, here’s a link to the Project for Emerging Nanotechnologies Nanoremediation Map. I’m not sure how exhaustive the listings are or how recent but it should give you some idea about the activities occurring in the US and around the world.

Danish nanotechnology-enabled product database

It’s called the Nanodatabase according to the Nov. 30, 2012 news item on Nanowerk (Note: I have removed a link),

The Danish Consumer Council and the Danish Ecological Council has in cooperation with DTU Environment developed a database, which help consumers identify more than 1,200 products that may contain nanomaterials. The Nanodatabase gives consumers a choice. [emphasis mine]

”Most consumers have no idea if there are nanomaterials or not in the goods they’re buying. And they have no way of finding out, so that they can avoid the products if they are worried about the potentially harmful effects” says Claus Jørgensen, Senior Advisor at the Danish Consumer Council.

This is why the Danish Ecological Council and the Danish Consumer Council in cooperation with experts from DTU [Technical University of Denmark] Environment has decided to launch the Nanodatabase. Now consumers can search the database to see if a certain product contains nanomaterials or is marketed as ‘nano’. This way the consumers can choose if they want the nanomaterials or not.

The database contains more than 1,200 products which contain nanomaterials or are marketed using the nano-claim. [emphasis mine]

“Until we know for sure that the use of nanotechnology is safe and the legislation is in place, we need a label that can help consumers make informed choices”, says Lone Mikkelsen [chemical expert from the Danish Ecological Council].

The two organisations hope that the English version of the database will help consumers in other countries. The hope is that consumers will report products that contain ‘nano’ or claim to be a nano product to the database.

This project reminds me of the Project on Emerging Nanotechnologies (PEN) and their consumer products inventory. I don’t believe they’re adding to that inventory any moreas the March 10, 2011 news release announcing over 1300 nanotechnology-enabled products (as claimed by manufacturers) in the inventory appears to have been PEN’s last. I think they, like the Danish Consumer Council and the Danish Ecological Council, were hoping to raise awareness.

Women in Europe for a Common Future advises precautionary principle for manufacture nanomaterials

Another organization advises the precautionary principle when dealing with nanomaterials. This time it’s the Women in Europe for a Common Future (WECF) organization and they’ve just released a position paper. From the March 30, 2012 news item on Nanowerk,

Women in Europe for a Common Future, an international network of over 100 women’s, environmental and health organisations implementing projects in 40 countries and advocating globally for a healthy environment, has released a position paper on nanoparticles and nanotechnology: Nano – The great unknown (pdf).

WECF recognizes that nanotechnologies could bring long-term profits and overall societal benefits. However, in order to make an overall judgment, data is needed regarding the hazards, exposure, risks and ethical consequences for humans, the environment and our society as a whole.

Maybe I’m getting grumpy these days but It seems to me that the time for describing ‘nanotechnology as the latest buzzword’ has passed. Here’s the opening sentence from the position paper,

Nanotechnology, the latest buzzword in the global technology revolution, is the science of ‘small things’: the de­signing, manipulating and engineer­ing of materials at nanoscale. (p. 1)

Also on page 1 is a claim as to the number of nanotechnology-enabled products on the market,

The number of consumer products on the world market claiming to contain nanomaterials exceeded 1300 already by 2010, and there are probably more, as the actual presence of nanomaterials is dif­ficult to identify.

The source for the number of nano products is not cited although WECF does list the Project for Emerging Nanotechnologies (PEN) and its product inventory in the bibliography. PEN’s inventory has no oversight (PEN has always been quite frank about this); anyone can register a product and claim there are nanomaterials in it.

Further in the position paper, Canada and California are mentioned,

Other regulatory entities too are work­ing on developing the first laws that can address the concerns on nanomaterials. Canada and the state of California, for example, took the step of imposing mandated disclosure requirements on nanomaterial use and toxicity assess­ment. Canada’s law of January 2009 targets domestic companies and institu­tions that manufacture or buy more than 1 kilogram of nanomaterial per year. According to these new regulations, these entities must now reveal how much nanomaterial they use, how they use it, and what they know about its toxicity. (p. 3)

I’m not familiar enough with the situation in California to comment on it but I am somewhat puzzled by the description of a Canadian law targeting domestic companies and institutions that manufacture or buy more than 1 kilogram of nanomaterials per year. There was a one time only requirement to report on how much nanomaterial was being imported into Canada but, as far as I’m aware, there is no law or regulation which states that this must be done on an ongoing basis. (You can read more about the reporting scheme in my April 12, 2010 posting.) This statement was not cited and I can’t find anything in the bibliography that might be the source for this information.

My problem with this position paper is that I can’t trust any of the information because the little I am familiar with contradicts their statements and they don’t support those statements with sources that I can research.
