Industry’s Response to EPA Proposed Nano Rule

National Nanomanufacturing Network - June 25, 2015 - 6:46am
EPA held a public meeting on June 11, 2015 on EPA’s Proposed Rule imposing one-time electronic reporting and recordkeeping requirements on manufacturers and processors of certain nanoscale materials under Section 8(a) of the Toxic Substances Control Act (TSCA). EPA began the meeting by clarifying that the Proposed Rule targets nanoscale versions of substances that had previously been exempt from reporting requirements. New nanoscale materials are already subject to TSCA and over 170 premanufacturing notices have been filed for those new materials, including many for carbon nanotubes. EPA’s goal for the rule is to provide missing information on nanoscale versions of existing substances to evaluate whether further regulation is needed. Commenters Five individuals made comments: Steven Gordon of 3M speaking on behalf of the American Chemistry Council; Dan Russell of Pixelligent New Technologies; Jo Anne Shatkin of Vireo Advisors; Martha Marrapese of Keller and Heckman LLP speaking on behalf of the NanoManufacturing Association; and Vincent Caprio of the NanoBusiness Commercialization Association. Issues Raised Definition of Reportable Chemical Substances. The definition of “reportable chemical substances” uses vague terms like “unique,” “novel,” and “trace,” which will make it difficult to determine whether something is a “reportable chemical substance.” The terms should be better defined and justified. Discrete Forms of Nanomaterials. EPA should provide better guidance on how to measure discrete forms of nanoscale materials because the model used will affect the resulting measurements. One commenter objected to certain properties chosen by EPA to determine whether a discrete form exists, such as dispersion stability and surface reactivity, because they are not sufficiently linked to risk to human health and environment. 135-Day Review Period. Most of the commenters objected to the 135-day review period, which is longer than the 90-day review of reports for new substances, including because of the adverse economic effects of the additional delay. Harmonizing U.S. and Canadian Approaches. EPA should reduce the burden on industry by aligning the forthcoming rule with the Canadian process (http://www.ec.gc.ca/lcpe-cepa/default.asp?lang=En n=1D804F45-1) announced earlier this year. Availability of Required Information. Companies will not have certain of the required information readily available, burdening industry and violating TSCA 8(a), which only authorizes EPA to require information that companies already have or can reasonably ascertain. What Next? Public comments are due on July 6, 2015, but EPA did not specify when it will respond to the comments and what that response will be. One commenter suggested that EPA re-propose the rule for additional comments after it has been revised. During Nanotech 2015, a nanotechnology conference and exposition that occurred the week following the public meeting, it was suggested that the Proposed Rule would likely be finalized in late 2016, requiring reporting in 2017. In the meantime, those potentially subject to the rule can review the proposed form companies would be required to submit under the new rule.

Printing with nanomaterials a cost-friendly, eco-friendly alternative

National Nanomanufacturing Network - June 25, 2015 - 3:44am
Researchers at Binghamton University are focusing on printed electronics: using inkjet technology to print electronic nanomaterials onto flexible substrates. When compared to traditional methods used in microelectronics fabrication, the new technology conserves material and is more environmentally friendly. Think of inkjet printing and you’ll likely picture an old printer in an office. Not so if you’re Timothy Singler, director of graduate studies and professor of mechanical engineering at Binghamton University. In the Transport Sciences Core at the Innovative Technologies Complex, Singler is collaborating with Paul Chiarot and Frank Yong, assistant professors of mechanical engineering, to study inkjet printing of functional materials. Functional materials are categorized in terms of the actions they can perform rather than on the basis of their origins. Solution-processed materials may have electrical, optical, chemical, magnetic, thermal or other functionalities. For example, silver is strongly electrically conductive and can be formulated into nanoparticle ink. However, Singler explains that printing with solution-processed nanomaterials instead of traditional inks is significantly more complex. "One really has to study how nanomaterials deposit on a substrate — what structures they form, how you can control them — because you’re dispersing the nanomaterials into a liquid so you can print them, and that liquid volatilizes, leaving only the material on the substrate. But the evaporation process and capillarity cause very complex flows that transport the material you’re trying to deposit in nonintuitive ways," Singler says. "These flows have to be controlled to achieve an optimal functional structure at the end."Source: Binghamton University, State University of New York (http://www.binghamton.edu/mpr//news-releases/news-release.html?id=2309)

NNI Publishes Workshop Report and Launches Web Portal on Nanosensors

National Nanomanufacturing Network - June 25, 2015 - 3:32am
The National Nanotechnology Coordination Office (NNCO) is pleased to announce the launch of a workshop report and a web portal, efforts coordinated through and in support of the Nanotechnology Signature Initiative 'Nanotechnology for Sensors and Sensors for Nanotechnology: Improving and Protecting Health, Safety, and the Environment' (http://www.nano.gov/SensorsNSIPortal) (Sensors NSI). Together, these resources help pave the path forward for the development and commercialization of nanotechnology-enabled sensors and sensors for nanotechnology. The workshop report is a summary of the National Nanotechnology Initiative (NNI)-sponsored event held September 11-12, 2014, entitled 'Sensor Fabrication, Integration, and Commercialization Workshop.' The goal of the workshop was to identify and discuss challenges that are faced by the sensor development community during the fabrication, integration, and commercialization of sensors, particularly those employing or addressing issues of nanoscale materials and technologies. Workshop attendees, including sensor developers and representative from Federal agencies, identified ways to help facilitate the commercialization of nanosensors, which include: Enhancing communication among researchers, developers, manufacturers, customers, and the Federal Government agencies that support and regulate sensor development. Leveraging resources by building testbeds for sensor developers. Improving access of university and private researchers to federally supported facilities. Encouraging sensor developers to consider and prepare for market and regulatory requirements early in the development process. In response to discussions at the workshop, the NNI has also launched an NSI Sensors web portal to share information on the sensors development landscape, including funding agencies and opportunities, federally supported facilities, regulatory guidance, and published standards. Ongoing dialogue and collaboration among various stakeholder groups will be critical to effectively transitioning nanosensors to market and to meeting the U.S. need for a reliable and robust sensor infrastructure. On Thursday June 25, 2015, from noon to 1 pm EDT, NNCO will host a webinar to summarize the highlights from the 2014 'Sensor Fabrication, Integration, and Commercialization Workshop' and to introduce the newly developed Sensors NSI Web Portal. The webinar will also feature a Q A segment with members of the public. Questions for the panel can be submitted to webinar@nnco.nano.gov from June 18 through the end of the webinar at 1 pm EDT on June 25, 2015. To view the workshop report in our library, visit http://eprints.internano.org/2232/ (http://eprints.internano.org/2232/) To visit the NSI Sensors web portal, visit http://www.nano.gov/SensorsNSIPortal (http://www.nano.gov/SensorsNSIPortal) To sign up for the NSI Sensors webinar, visit http://www.nano.gov/SensorsPortalWebinar (http://www.nano.gov/SensorsPortalWebinar) Source: NNI (http://www.nano.gov/node/1427)
