Researchers from the National Institute of Standards and Technology and the Naval Research Laboratory have developed a new way to introduce magnetic impurities in a semiconductor crystal by prodding it with a scanning tunneling microscope (STM). Detailed in a recent paper, this technique will enable researchers to selectively implant atoms in a crystal one at a time to learn about its electrical and magnetic properties on the atomic scale. http://www.physorg.com/news178978543.html Nanotechnology Wed, 02 Dec 2009 12:16:57 EST news178978543 (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) -- In the 2,000 or so years since the Roman Empire employed a naturally occurring form of cement to build a vast system of concrete aqueducts and other large edifices, researchers have analyzed the molecular structure of natural materials and created entirely new building materials such as steel, which has a well-documented crystalline structure at the atomic scale. http://www.physorg.com/news171725814.html Nanotechnology Wed, 09 Sep 2009 14:37:37 EST news171725814 (PhysOrg.com) -- Scientists at the University of Liverpool have developed a molecular structure that could help create current-generating machines at the nanoscale. http://www.physorg.com/news162640123.html Nanotechnology Wed, 27 May 2009 10:49:13 EST news162640123 (PhysOrg.com) -- Try to picture putting some atoms under a microscope. Even if you could pick them up, put them on a slide and get them to stay still, you still could not see them with even the most powerful optical microscope. http://www.physorg.com/news155235288.html Nanotechnology Mon, 02 Mar 2009 16:55:22 EST news155235288 Nanotubes, the tiny honeycomb cylinders of carbon atoms only a few nanometers wide, are perhaps the signature material of modern engineering research, but actually trying to organize the atomic scale rods is notoriously like herding cats. A new study* from the National Institute of Standards and Technology and Rice University, however, offers an inexpensive process that gets nanotubes to obediently line themselves up -- that is, self-assemble -- in neat rows, more like ducks. http://www.physorg.com/news151090330.html Nanotechnology Tue, 13 Jan 2009 17:32:10 EST news151090330
