(PhysOrg.com) -- Rice University scientists today unveiled a method for the industrial-scale processing of pure carbon-nanotube fibers that could lead to revolutionary advances in materials science, power distribution and nanoelectronics. The result of a nine-year program, the method builds upon tried-and-true processes that chemical firms have used for decades to produce plastics. The research is available online in the journal Nature Nanotechnology. http://www.physorg.com/news176396559.html Nanotechnology Mon, 02 Nov 2009 15:04:34 EST news176396559 (PhysOrg.com) -- Researchers from the MESA+ Institute for Nanotechnology at the University of Twente, The Netherlands, working with American researchers, have succeeded in using an electrical signal to control both the elastic and the magnetic properties of a nanomaterial at a very localized level. This opens up new possibilities for data storage with very high data densities. Their findings are to be published in November in the leading scientific journal Nature Nanotechnology. http://www.physorg.com/news175445828.html Nanotechnology Thu, 22 Oct 2009 15:58:37 EST news175445828 (PhysOrg.com) -- Taking nanomaterials to a new level of structural complexity, scientists have determined how to introduce kinks into arrow-straight nanowires, transforming them into zigzagging two- and three-dimensional structures with correspondingly advanced functions. http://www.physorg.com/news175339313.html Nanotechnology Wed, 21 Oct 2009 10:23:16 EST news175339313 The burgeoning research fields of nanoscience and nanotechnology are commonly thought to be highly multidisciplinary because they draw on many areas of science and technology to make important advances. http://www.physorg.com/news171521941.html Nanotechnology Mon, 07 Sep 2009 06:16:39 EST news171521941 Biomolecular computers, made of DNA and other biological molecules, only exist today in a few specialized labs, remote from the regular computer user. Nonetheless, Tom Ran and Shai Kaplan, research students in the lab of Prof. Ehud Shapiro of the Weizmann Institute's Biological Chemistry, and Computer Science and Applied Mathematics Departments have found a way to make these microscopic computing devices 'user friendly,' even while performing complex computations and answering complicated queries. http://www.physorg.com/news168510956.html Nanotechnology Mon, 03 Aug 2009 09:40:51 EST news168510956 (PhysOrg.com) -- McGill researchers have succeeded in finding a new way to manufacture nanotubes, one of the important building blocks of the nanotechnology of the future. Their building material? Biological DNA. http://www.physorg.com/news158858442.html Nanotechnology Mon, 13 Apr 2009 16:21:23 EST news158858442 Chemists at New York University and China's Nanjing University have developed a two-armed nanorobotic device that can manipulate molecules within a device built from DNA. The device is described in the latest issue of the journal Nature Nanotechnology. http://www.physorg.com/news153927342.html Nanotechnology Sun, 15 Feb 2009 13:36:30 EST news153927342 (PhysOrg.com) -- Physicists have set a new world record for the smallest writing, with features of letters as small as 0.3 nanometers, or roughly one third of a billionth of a meter. The accomplishment demonstrates that information can be stored more densely than previously thought. The research was conducted at the Stanford Institute for Materials and Energy Sciences (SIMES), a joint institute of Stanford University and the U.S. Department of Energy's SLAC National Accelerator Laboratory. http://www.physorg.com/news152385929.html Nanotechnology Wed, 28 Jan 2009 17:26:44 EST news152385929 (PhysOrg.com) -- Researchers have found a way to incorporate silicon into the structure of rechargeable lithium-ion batteries, which are used to power a wide variety of portable electronic devices, including digital cameras and cell phones. The group's method, using a nanowire form of silicon, overcomes the roadblocks that have prevented the use of silicon and may help extend the batteries' lifetimes. http://www.physorg.com/news151667477.html Nanotechnology Tue, 20 Jan 2009 09:52:51 EST news151667477 (PhysOrg.com) -- A joint team of researchers at CIC nanoGUNE (San Sebastian, Spain) and the Max Planck Institutes of Biochemistry and Plasma Physics (Munich, Germany) report the non-invasive and nanoscale resolved infrared mapping of strain fields in semiconductors. The method, which is based on near-field microscopy, opens new avenues for analyzing mechanical properties of high-performance materials or for contact-free mapping of local conductivity in strain-engineered electronic devices (Nature Nanotechnology, advanced online publication, 11 Jan. 2009). http://www.physorg.com/news150998994.html Nanotechnology Mon, 12 Jan 2009 16:09:54 EST news150998994
