The Nanoscale Science, Engineering, and Technology (NSET) Subcommittee of the National Science and Technology Council's Committee on Technology today released a document describing the National Nanotechnology Initiative's (NNI) strategy for addressing priority research on the environment, health and safety (EHS) aspects of nanomaterials.
Researchers in Civil and Environmental Engineering at MIT reveal that the strength of a biological material like spider silk lies in the specific geometric configuration of structural proteins, which have small clusters of weak hydrogen bonds that work cooperatively to resist force and dissipate energy.
Finland's national nanotechnology initiative FinNano is rapidly advancing on the international scene. Its record-sized delegation was highly visible at nano tech 2008, the world's largest nanotechnology exhibition in Tokyo. Several cooperation agreements were established during the event. One of the most important was the extension of cooperation between NOF Corporation, a consortium of Finnish industrial companies, and the University of Oulu.
Microchip processing technology is being updated at faster and faster rates in our age of silicon chip wizardry. By the time you unpack your smart new laptop or digital camera the technology that went into making it is already becoming outdated. But a solution to the problem is now at hand. Researchers working on a project called PICMOS, with EU funding of EUR 2.5 million, have developed new technologies to produce and combine semiconductor microlasers with silicon wave guides for new, efficient and powerful optical connections.
Singapore's focused transformation into a scientific powerhouse in the biomedical sciences and physical sciences and engineering will stage a presence this week in Boston at the annual meetings of the American Association for the Advancement of Sciences (AAAS) and the Fulbright Academy of Science and Technology.
Nanotechnology researchers at the Georgia Institute of Technology are developing a shirt that harvests energy from the wearer's physical motion and converts it into electricity for powering small electronic devices worn by soldiers in the field, hikers and other users.
The National Nanotechnology Coordination Office, Arlington, Va., the Department of Energy's Brookhaven National Laboratory, Upton, N.Y., and the National Science Foundation, Arlington, Va. invites media and members of the public to a roundtable on nanoenergy and nanomedicine on Feb. 15 in Boston.
Researchers at Stanford University are looking closer than ever at how the three-dimensional twists and turns in a riboswitch come together by grabbing it and tugging it straight. By physically pulling on this loopy RNA, they have determined for the first time how a three-dimensional molecular structure folds, step by step.
Stuart Wolf, a professor in both the University of Virginia's Department of Physics and its Department of Materials Science and Engineering, has been named the new director of U.Va.'s Institute for Nanoscale and Quantum Scientific and Technological Advanced Research, or nanoSTAR.
New photovoltaic technologies, such as the recent introduction of thin-film cadmiumÔ??telluride materials, have nearly doubled the efficiency of solar cells within the past few years. But the methods of making the materials used for photovoltaic cells, whether from silicon, metal, or other material, have raised doubts about the environmental friendliness of these passive energy collectors.
Bacteria often get bad press, with those found in water often linked to illness and disease. But researchers at The University of Nottingham are using these tiny organisms alongside the very latest membrane filtration techniques to improve and refine water cleaning technology.
