(with audio) By making gold nanoparticles with different shapes, researchers have identified how surface atomic structures affect friction and adhesion.
The National Nanotechnology Initiative today published the proceedings of a technical interchange meeting on Realizing the Promise of Carbon Nanotubes: Challenges, Opportunities, and the Pathway to Commercialization" (http://www.nano.gov/node/1339) held at the National Aeronautics and Space Administration (NASA) Headquarters on September 15, 2014. This meeting brought together some of the Nations leading experts in carbon nanotube materials to identify, discuss, and report on technical barriers to the production of carbon nanotube (CNT)-based bulk and composite materials with properties that more closely match those of individual CNTs and to explore ways to overcome these barriers. A number of common themes and potential future research and development priorities emerged: Increased efforts devoted to manufacturing, quality control, and scale-up.Improvements in the mechanical and electrical properties of CNT-based bulk materials to approach the properties of individual CNTs.More effective use of simulation and modeling to provide insight into the fundamentals of the CNT growth process.Improved understanding of the properties of bulk CNT-containing materials at longer length scales.Standard materials and protocols to guide the testing of CNT-based products for commercial applications.Life cycle assessments for gauging commercial readiness.Use of public-private partnerships or other collaboration vehicles to leverage resources and expertise to solve these technical challenges and accelerate commercialization. The outcomes of this meeting, as detailed in this report, will help inform the future directions of theNNI Nanotechnology Signature Initiative Sustainable Nanomanufacturing: Creating the Industries of the Future, (http://nano.gov/NSINanomanufacturing) which was launched in 2010 to accelerate the development of industrial-scale methods for manufacturing functional nanoscale systems.

The Presidents Budget for Fiscal Year 2016 provides $1.5 billion for the National Nanotechnology Initiative (NNI), a continued Federal investment in support of the Presidents priorities and innovation strategy. Cumulatively totaling more than $22 billion since the inception of the NNI in 2001, this funding reflects nanotechnologys potential to significantly improve our fundamental understanding and control of matter at the nanoscale and to translate that knowledge into solutions for critical national needs. Nearly half of the requested budget is dedicated to applications-focused R D and support for the Nanotechnology Signature Initiatives (NSIs), reflecting an increased emphasis within the NNI on accelerating the transition of nanotechnology-based discoveries from lab to market. The NSIs are multiagency initiatives designed to accelerate innovation in areas of national priority through enhanced interagency coordination and collaboration. Furthermore, the NNI has continued to grow its hallmark environmental, health, and safety (EHS) activities, which now account for more than 10% of the NNIs total budget (7% in dedicated EHS investments, as shown in the figure at left, plus approximately 3% in additional EHS-related investments within the NSIs). Right now, the NNI is focused on innovations that support national priorities, while maintaining a strong foundation of fundamental research in nanoscience, says Dr. Michael Meador, Director of the National Nanotechnology Coordination Office. Our goal is to create an environment to foster technology transfer and new applications today, while supporting the basic research that will provide a continuing pipeline of new discoveries to enable future revolutionary applications tomorrow. The Presidents 2016 Budget supports nanoscale science, engineering, and technology R D at 11 agencies; another 9 agencies have nanotechnology-related mission interests or regulatory responsibilities. The NNI Supplement to the Presidents 2016 Budget documents activities of these agencies in addressing the goals and objectives of the NNI.
