IBM Research Alliance Produces Industry’s First 7nm Node Test Chips

July 9, 2015 - 7:29am
An alliance led by IBM Research (NYSE:IBM) today announced that it has produced the semiconductor industry’s first 7nm (nanometer) node test chips with functioning transistors. The breakthrough, accomplished in partnership with GLOBALFOUNDRIES and Samsung at SUNY Polytechnic Institute’s Colleges of Nanoscale Science and Engineering (SUNY Poly CNSE), could result in the ability to place more than 20 billion tiny switches -- transistors -- on the fingernail-sized chips that power everything from smartphones to spacecraft.To achieve the higher performance, lower power and scaling benefits promised by 7nm technology, researchers had to bypass conventional semiconductor manufacturing approaches. Among the novel processes and techniques pioneered by the IBM Research alliance were a number of industry-first innovations, most notably Silicon Germanium (SiGe) channel transistors and Extreme Ultraviolet (EUV) lithography integration at multiple levels.Industry experts consider 7nm technology crucial to meeting the anticipated demands of future cloud computing and Big Data systems, cognitive computing, mobile products and other emerging technologies. Part of IBM’s $3 billion, five-year investment in chip R D (announced in 2014), this accomplishment was made possible through a unique public-private partnership with New York State and joint development alliance with GLOBALFOUNDRIES, Samsung, and equipment suppliers. The team is based at SUNY Poly’s NanoTech Complex in Albany.“For business and society to get the most out of tomorrow’s computers and devices, scaling to 7nm and beyond is essential,” said Arvind Krishna, senior vice president and director of IBM Research. “That’s why IBM has remained committed to an aggressive basic research agenda that continually pushes the limits of semiconductor technology. Working with our partners, this milestone builds on decades of research that has set the pace for the microelectronics industry, and positions us to advance our leadership for years to come.”Microprocessors utilizing 22nm and 14nm technology power today’s servers, cloud data centers and mobile devices, and 10nm technology is well on the way to becoming a mature technology. The IBM Research-led alliance achieved close to 50 percent area scaling improvements over today’s most advanced technology, introduced SiGe channel material for transistor performance enhancement at 7nm node geometries, process innovations to stack them below 30nm pitch and full integration of EUV lithography at multiple levels. These techniques and scaling could result in at least a 50 percent power/performance improvement for next generation mainframe and POWER systems that will power the Big Data, cloud and mobile era.“Governor Andrew Cuomo’s trailblazing public-private partnership model is catalyzing historic innovation and advancement. Today’s announcement is just one example of our collaboration with IBM, which furthers New York State’s global leadership in developing next generation technologies,” said Dr. Michael Liehr, SUNY Poly Executive Vice President of Innovation and Technology and Vice President of Research. “Enabling the first 7nm node transistors is a significant milestone for the entire semiconductor industry as we continue to push beyond the limitations of our current capabilities.”"Today’s announcement marks the latest achievement in our long history of collaboration to accelerate development of next-generation technology," said Gary Patton, CTO and Head of Worldwide R D at GLOBALFOUNDRIES. "Through this joint collaborative program based at the Albany NanoTech Complex, we are able to maintain our focus on technology leadership for our clients and partners by helping to address the development challenges central to producing a smaller, faster, more cost efficient generation of semiconductors." The 7nm node milestone continues IBM’s legacy of historic contributions to silicon and semiconductor innovation. They include the invention or first implementation of the single cell DRAM, the Dennard Scaling Laws, chemically amplified photoresists, copper interconnect wiring, Silicon on Insulator, strained engineering, multi core microprocessors, immersion lithography, high speed SiGe, High-k gate dielectrics, embedded DRAM, 3D chip stacking and Air gap insulators.IBM and SUNY Poly have built a highly successful, globally recognized partnership at the multi-billion dollar Albany NanoTech Complex, highlighted by the institution's Center for Semiconductor Research (CSR), a $500 million program that also includes the world's leading nanoelectronics companies. The CSR is a long-term, multi-phase, joint R D cooperative program on future computer chip technology. It continues to provide student scholarships and fellowships at the university to help prepare the next generation of nanotechnology scientists, researchers and engineers.For more information about SUNY Polytechnic Institute, visit www.sunycnse.com (http://www.sunycnse.com) and www.sunypoly.edu (http://www.sunypoly.edu) .For more information on IBM Research, visit www.research.ibm.com (http://www.research.ibm.com).Contact(s) informationChristine VuIBM Media Relations1 (914) 945-2755vuch@us.ibm.comSource: https://www-03.ibm.com/press/us/en/pressrelease/47301.wss (https://www-03.ibm.com/press/us/en/pressrelease/47301.wss)

Industry’s Response to EPA Proposed Nano Rule

June 25, 2015 - 11:46am
Katy E. Ward & Jo Anne ShatkinEPA 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 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. Source: National Law Review

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

June 25, 2015 - 8:44am
Binghampton University, Media & Public RelationsResearchers 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. Timothy J. Singler, professor and graduate director of Mechanical Engineering at the Watson School of Engineering and Applied Sciences and graduate student Liang Liu, photographed at his lab in the Engineering and Science Building at the Innovative Technologies 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

Carbon Nanotube-Based Water Desalination and Purification Technology Awarded Patent

June 11, 2015 - 9:24am
Tracey ReganSomenath Mitra, distinguished professor of chemistry and environmental science, was awarded a patent last month for a next-generation water desalination and purification technology that uses uniquely absorbent carbon nanotubes to remove salt and pollutants from brackish water and industrial effluent for reuse by businesses and households. Mitra’s new carbon nanotube immobilized membrane (CNIM) is an energy-efficient device designed to filter higher concentrations of salt than is currently feasible through reverse osmosis, one of the standard industry processes. It is also used to remove pollutants such as volatile organic compounds (VOCs) – chemicals routinely used in solvents – from water. “There is a huge and growing demand for potable water coming from developing nations that are modernizing their infrastructure to improve living conditions. At the same time, droughts caused by climate change are reducing supply in many regions of the world, including parts of the U.S.,” Mitra said. “Our hope is to expand the supply of water in places that really need it, while also reducing costs for industry.” Mitra’s distillation process runs on energy-efficient fuels such as waste heat, an industrial by-product, and solar energy. Membrane distillation is a water desalination process in which heated salt water passes through a tube-like membrane, called a hollow fiber, which allows only pure water vapor to permeate its walls.  Potable water emerges from the net flux of water vapor which moves from the warm to the cool side of the membrane where it condenses. Certain industries such as semiconductor manufacturing and pharmaceutical processing also require ultra-pure water for their operations. Mitra, who has conducted research on carbon nanotubes for the past 15 years, created a novel architecture for the membrane distillation process by immobilizing carbon nanotubes, which are an atom thick and about 10,000 times smaller than a human hair in diameter, in the membrane pores. Ken Gethard, a former doctoral student who helped him develop it, is the co-inventor on the patent. “One of the key characteristics of carbon nanotubes is their capacity to both rapidly absorb water vapor  as well as industrial contaminants, including volatile organic compounds (VOCs), and then easily release them,” he notes. In the case of fracking, the fresh water and chemicals that are pumped into the ground to release natural gas trapped beneath rocks absorb high concentrations of salt from the soil they pass through before returning as polluted water in need of treatment. Reverse osmosis, which relies on power-driven pump pressure to force water through a membrane, is not commonly used to treat this so-called produced water because it typically contains very high concentrations of salt, requiring extremely high pressure. The electric power industry, which uses a vast amount of water to cool its generators, is also eager to come up with more efficient processes to treat its wastewater, including the incorporation of waste heat. “Our hope is to dramatically improve overall water and energy utilization,” Mitra said.

(Image: Jacobs School of Engineering/UC San Diego) Imagine a fabric that will keep your body at a comfortable temperature—regardless of how hot or cold it actually is. That’s the goal of an engineering project at the University of California, San Diego, funded with a $2.6M grant from the U.S. Department of Energy’s Advanced Research Projects Agency – Energy (ARPA-E). Wearing this smart fabric could potentially reduce heating and air conditioning bills for buildings and homes. The project, named ATTACH (Adaptive Textiles Technology with Active Cooling and Heating), is led by Joseph Wang, distinguished professor of nanoengineering at UC San Diego. By regulating the temperature around an individual person, rather than a large room, the smart fabric could potentially cut the energy use of buildings and homes by at least 15 percent, Wang noted. “In cases where there are only one or two people in a large room, it’s not cost-effective to heat or cool the entire room,” said Wang. “If you can do it locally, like you can in a car by heating just the car seat instead of the entire car, then you can save a lot of energy.” The smart fabric will be designed to regulate the temperature of the wearer’s skin—keeping it at 93° F—by adapting to temperature changes in the room. When the room gets cooler, the fabric will become thicker. When the room gets hotter, the fabric will become thinner. To accomplish this feat, the researchers will insert polymers that expand in the cold and shrink in the heat inside the smart fabric. “Regardless if the surrounding temperature increases or decreases, the user will still feel the same without having to adjust the thermostat,” said Wang. “93° F is the average comfortable skin temperature for most people,” added Renkun Chen, assistant professor of mechanical and aerospace engineering at UC San Diego, and one of the collaborators on this project. Chen’s contribution to ATTACH is to develop supplemental heating and cooling devices, called thermoelectrics, that are printable and will be incorporated into specific spots of the smart fabric. The thermoelectrics will regulate the temperature on “hot spots”—such as areas on the back and underneath the feet—that tend to get hotter than other parts of the body when a person is active. “This is like a personalized air-conditioner and heater,” said Chen. Saving energy “With the smart fabric, you won’t need to heat the room as much in the winter, and you won’t need to cool the room down as much in the summer. That means less energy is consumed. Plus, you will still feel comfortable within a wider temperature range,” said Chen. The researchers are also designing the smart fabric to power itself. The fabric will include rechargeable batteries, which will power the thermoelectrics, as well as biofuel cells that can harvest electrical power from human sweat. Plus, all of these parts—batteries, thermoelectrics and biofuel cells—will be printed using the technology developed in Wang’s lab to make printable wearable devices. These parts will also be thin, stretchable and flexible to ensure that the smart fabric is not bulky or heavy. “We are aiming to make the smart clothing look and feel as much like the clothes that people regularly wear. It will be washable, stretchable, bendable and lightweight. We also hope to make it look attractive and fashionable to wear,” said Wang. In terms of price, the team has not yet concluded how much the smart clothing will cost. This will depend on the scale of production, but the printing technology in Wang’s lab will offer a low-cost method to produce the parts. Keeping the costs down is a major goal, the researchers said. The research team Professor Joseph Wang, Department of NanoEngineering Wang, the lead principal investigator of ATTACH, has pioneered the development of wearable printable devices, such as electrochemical sensors and temporary tattoo-based biofuel cells. He is the chair of the nanoengineering department and the director for the Center for Wearable Sensors at UC San Diego. His extensive expertise in printable, stretchable and wearable devices will be used here to make the proposed flexible biofuel cells, batteries and thermoelectrics. Assistant Professor Renkun Chen, Department of Mechanical and Aerospace Engineering Chen specializes in heat transfer and thermoelectrics. His research group works on physics, materials and devices related to thermal energy transport, conversion and management. His specialty in these areas will be used to develop the thermal models and the thermoelectric devices. Associate Professor Shirley Meng, Department of NanoEngineering Meng’s research focuses on energy storage and conversion, particularly on battery cell design and testing. At UC San Diego, she established the Laboratory for Energy Storage and Conversion and is the inaugural director for the Sustainable Power and Energy Center. Meng will develop the rechargeable batteries and will work on power integration throughout the smart fabric system. Professor Sungho Jin, Department of Mechanical and Aerospace Engineering Jin specializes in functional materials for applications in nanotechnology, magnetism, energy and biomedicine. He will design the self-responsive polymers that change in thickness based on changes in the surrounding temperature. Dr. Joshua Windmiller, CEO of Electrozyme LLC Windmiller, former Ph.D. student and postdoc in Wang’s nanoengineering lab, is an expert in printed biosensors, bioelectronics and biofuel cells. He co-founded Electrozyme LLC, a startup devoted to the development of novel biosensors for application in the personal wellness and healthcare domains. Electrozyme will serve as the industrial partner for ATTACH and will lead the efforts to test the smart fabric prototype and bring the technology into the market.

New 'designer carbon' from Stanford boosts battery performance

May 29, 2015 - 1:02pm
Mark Shwartz, Precourt Institute for Energy, Stanford News ServiceA new 'designer carbon' invented by Stanford scientists significantly improved the power delivery rate of this supercapacitor. (Photo credit: John To and Zheng Chen)Stanford University scientists have created a new carbon material that significantly boosts the performance of energy-storage technologies. Their results are featured on the cover of the journal ACS Central Science. "We have developed a 'designer carbon' that is both versatile and controllable," said Zhenan Bao, the senior author of the study and a professor of chemical engineering at Stanford. "Our study shows that this material has exceptional energy-storage capacity, enabling unprecedented performance in lithium-sulfur batteries and supercapacitors." According to Bao, the new designer carbon represents a dramatic improvement over conventional activated carbon, an inexpensive material widely used in products ranging from water filters and air deodorizers to energy-storage devices. "A lot of cheap activated carbon is made from coconut shells," Bao said. "To activate the carbon, manufacturers burn the coconut at high temperatures and then chemically treat it." The activation process creates nanosized holes, or pores, that increase the surface area of the carbon, allowing it to catalyze more chemical reactions and store more electrical charges. But activated carbon has serious drawbacks, Bao said. For example, there is little interconnectivity between the pores, which limits their ability to transport electricity. "With activated carbon, there's no way to control pore connectivity," Bao said. "Also, lots of impurities from the coconut shells and other raw starting materials get carried into the carbon. As a refrigerator deodorant, conventional activated carbon is fine, but it doesn't provide high enough performance for electronic devices and energy-storage applications." 3-D networksInstead of using coconut shells, Bao and her colleagues developed a new way to synthesize high-quality carbon using inexpensive – and uncontaminated – chemicals and polymers. The process begins with conducting hydrogel, a water-based polymer with a spongy texture similar to soft contact lenses. "Hydrogel polymers form an interconnected, three-dimensional framework that's ideal for conducting electricity," Bao said. "This framework also contains organic molecules and functional atoms, such as nitrogen, which allow us to tune the electronic properties of the carbon." For the study, the Stanford team used a mild carbonization and activation process to convert the polymer organic frameworks into nanometer-thick sheets of carbon. "The carbon sheets form a 3-D network that has good pore connectivity and high electronic conductivity," said graduate student John To, a co-lead author of the study. "We also added potassium hydroxide to chemically activate the carbon sheets and increase their surface area." The result: designer carbon that can be fine-tuned for a variety of applications. "We call it designer carbon because we can control its chemical composition, pore size and surface area simply by changing the type of polymers and organic linkers we use, or by adjusting the amount of heat we apply during the fabrication process," To said. For example, raising the processing temperature from 750 degrees Fahrenheit (400 degrees Celsius) to 1,650 F (900 C) resulted in a 10-fold increase in pore volume. Subsequent processing produced carbon material with a record-high surface area of 4,073 square meters per gram – the equivalent of three American football fields packed into an ounce of carbon. The maximum surface area achieved with conventional activated carbon is about 3,000 square meters per gram. "High surface area is essential for many applications, including electrocatalysis, storing energy and capturing carbon dioxide emissions from factories and power plants," Bao said. SupercapacitorsTo see how the new material performed in real-world conditions, the Stanford team fabricated carbon-coated electrodes and installed them in lithium-sulfur batteries and supercapacitors. "Supercapacitors are energy-storage devices widely used in transportation and electronics because of their ultra-fast charging and discharging capability," said postdoctoral scholar Zheng Chen, a co-lead author. "For supercapacitors, the ideal carbon material has a high surface area for storing electrical charges, high conductivity for transporting electrons and a suitable pore architecture that allows for the rapid movement of ions from the electrolyte solution to the carbon surface." In the experiment, a current was applied to supercapacitors equipped with designer-carbon electrodes. The results were dramatic. Electrical conductivity improved threefold compared to supercapacitor electrodes made of conventional activated carbon. "We also found that our designer carbon improved the rate of power delivery and the stability of the electrodes," Bao added. BatteriesTests were also conducted on lithium-sulfur batteries, a promising technology with a serious flaw: When lithium and sulfur react, they produce molecules of lithium polysulfide, which can leak from the electrode into the electrolyte and cause the battery to fail. The Stanford team discovered that electrodes made with designer carbon can trap those pesky polysulfides and improve the battery's performance. "We can easily design electrodes with very small pores that allow lithium ions to diffuse through the carbon but prevent the polysulfides from leaching out," Bao said. "Our designer carbon is simple to make, relatively cheap and meets all of the critical requirements for high-performance electrodes." Other Stanford co-authors of the study are graduate student Jiajun He; postdoctoral scholars Hongbin Yao, Kwanpyo Kim and Ho-Hsiu Chou; visiting scholar Lijia Pan, and professors Jennifer Wilcox and Yi Cui. The study was partially funded by the Global Climate and Energy Project and the Precourt Institute for Energy at Stanford. Additional support was provided by the SLAC National Accelerator Laboratory and the SUNCAT Center for Interface Science and Catalysis at Stanford.

Global Nano-Enabled Packaging Market For Food and Beverages Will Reach $15.0 billion in 2020

May 28, 2015 - 3:37pm
Glen Hare, Persistence Market ResearchAccording to a new market report published by Persistence Market Research “Global Market Study on Nano-Enabled Packaging For Food and Beverages: Intelligent Packaging to Witness Highest Growth by 2020”, the global nano enabled packaging market for food and beverages industry was worth USD 6.5 billion in 2013 and is expected to grow at a CAGR of 12.7% during 2014 to 2020, to reach an estimated value of USD 15.0 billion in 2020. The global progress in technologies is making lives simpler and safer. Nanotechnology is one such field which is dynamically progressing and is contributing to the development of several industries, including food and beverages packaging. Nano-enabled packaging gives longer shelf life to food and beverages as compared to traditional plastic packaging. Food and beverages packaging is done through two different technologies under nano-enabled packaging-active and intelligent packaging. Active packaging has a comparativelylarger market than intelligent packaging. Intelligent packaging is growing at a faster rate as compared to the active packaging. Customers prefer traceable food and beverages packaging, since it offers information such as expiry date and best use period, present state of the consumables. The radio frequency identification (RFID) tags keep customers informed about the state of the food within the packaging. Intelligent packaging is mostly used for fruits and vegetables, meat products, and beverages. Stricter regulations associated with active packaging have been stimulating the use of intelligent packaging in Europe and North America. Intelligent packaging in the U.S. is growing mainly due to the increasing demand for fresh fruits and vegetables. Americans are shifting their breakfast preference from junk foods to fresh alternatives. The U.S. is one of the largest producers and exporters of cherries globally. With the ease in trade regulations, fruit exports of the U.S. have increased. In September 2011, the U.S. Department of Agriculture (USDA) announced that after ten years of negotiations, U.S. cherries can be exported to Western Australia, one of the most important markets for cherries. The increasing demand for intelligent packaging in international trade (especially in fruits) is laying out opportunities for this technology in food packaging. The Food Safety and Modernization Act (FSMA) proposed by FDA in 2011 is another growth indicator for intelligent packaging wherein the fresh produce, including fruits and vegetables, are required to be scientifically grown, harvested, packaged, and stored. The farm products that come in the act’s domain are lettuce, spinach, cantaloupe, tomatoes, sprouts, mushrooms, onions, peppers, cabbage, citrus produce, strawberries, and walnuts. Nano-enabled packaging finds its application in several industries, including bakery, meat, beverages, fruit and vegetables, prepared foods, and others. The increasing demand for meat products, beverages, vegetables, and prepared foods is expected to drive their respective nano-enabled packaging markets, while the market share of bakery products is expected to decline on account of the rapid growth of other application segments. Nanotechnology is at a nascent stage and, therefore, usage of nano-enabled packaging is low in the food and beverages industry. Limited numbers of buyers have more leverage to negotiate with nanotechnology companies. On the other hand, there is a plethora of companies providing nano-enabled packaging solutions to the food and beverages industry. Nano-enabled packaging market for food and beverage is very competitive with a large number of players offering an array of patented products. The major players in this industry include Amcor Limited, Bemis Company, Inc., Chevron Phillips Chemical Company, L.L.C., Klöckner Pentaplast, Sealed Air, and Tetra Pak International S.A.

New Initiatives to Accelerate the Commercialization of Nanotechnology

May 28, 2015 - 3:21pm
Lloyd Whitman, Assistant Director for Nanotechnology, OSTPOn May 20th, 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. Participants in the White House Forum on Small Business Challenges to Commercializing Nanotechnology. (Photo credit: Lloyd Whitman) Over the last fifteen years, the Federal government has invested over $20 billion in nanotechnology R&D as part of the National Nanotechnology Initiative (NNI), working towards breakthroughs such as smart anticancer therapeutics that will destroy tumors while leaving healthy cells untouched, and lighter, thinner body armor that could save the lives of America’s soldiers. A recent review of the NNI by the President’s Council of Advisors on Science and Technology (PCAST) concluded that: “…the nanotechnology field is at a critical transition point and has entered its second era, which we call NNI 2.0.  This next technological generation will see the evolution from nanoscale components to interdisciplinary nano‐systems and the movement from a foundational research‐based initiative to one that also provides the necessary focus to ensure rapid 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, supported by the National Nanotechnology Coordination Office, 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. As the President observed in his most recent State of the Union, “Twenty-first century businesses will rely on American science and technology, research and development.”  We call on all sectors of the nanotechnology community to identify additional ways to work together and make sure more of those businesses are built on nanoscience and nanotechnology.
