Scientists at the U.S. Department of Energy's Argonne National Laboratory are developing a way to control the Casimir force, a quantum mechanical force, which attracts objects when they are only hundred nanometers apart. http://www.physorg.com/news179677332.html Nanotechnology Thu, 10 Dec 2009 14:50:01 EST news179677332 A team of engineers from the University of Pennsylvania has transformed simple nanowires into reconfigurable materials and circuits, demonstrating a novel, self-assembling method for chemically creating nanoscale structures that are not possible to grow or obtain otherwise. http://www.physorg.com/news175513114.html Nanotechnology Fri, 23 Oct 2009 10:39:20 EST news175513114 (PhysOrg.com) -- To power a very small device like a pacemaker or a transistor, you need an even smaller generator. The components that operate the generator are smaller yet, and the efficiency of those foundational components is critical to the performance of the overall device. http://www.physorg.com/news175444804.html Nanotechnology Thu, 22 Oct 2009 15:52:12 EST news175444804 (PhysOrg.com) -- The trail to a new multiferroic started with the theories of a U.S. Department of Energy's Argonne National Laboratory scientist and ended with a multidisciplinary collaboration that created a material with potential impact on next generation electronics. http://www.physorg.com/news175279911.html Physics Tue, 20 Oct 2009 18:08:32 EST news175279911 (PhysOrg.com) -- Scientists from the U.S. Department of Energy's Argonne National Laboratory and the University of Chicago's Brain Tumor Center have developed a way to target brain cancer cells using inorganic titanium dioxide nanoparticles bonded to soft biological material. http://www.physorg.com/news169904314.html Nanotechnology Wed, 19 Aug 2009 12:39:03 EST news169904314 Catalysts do function, despite the fact that not all the chemical reactions (and partial reactions) which occur are fully understood, including those which take place during the treatment of automobile exhaust. If scientists understood these processes better not only would they be able to optimize exhaust gas catalysts but also other phenomena which are observed on surfaces, for instance when molecules orient themselves in either right or left handed fashion (i.e. as an image or mirror image). Knowing this would, not least, open new avenues of development in pharmacology for the manufacturers of medicines. http://www.physorg.com/news162828115.html Nanotechnology Fri, 29 May 2009 15:02:32 EST news162828115 Argonne Center for Nanoscale Materials staff in the Nanofabrication & Devices Group together with collaborative users from the University of Wisconsin-Milwaukee have fabricated a miniaturized gas sensor using hybrid nanostructures consisting of SnO2 nanocrystals supported on multiwalled carbon nanotubes (MWCNTs). http://www.physorg.com/news162656823.html Nanotechnology Wed, 27 May 2009 15:28:08 EST news162656823 (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 (PhysOrg.com) -- Folding paper into shapes such as a crane or a butterfly is challenging enough for most people. Now imagine trying to fold something that's about a hundred times thinner than a human hair and then putting it to use as an electronic device. http://www.physorg.com/news154796282.html Nanotechnology Wed, 25 Feb 2009 14:58:37 EST news154796282 (PhysOrg.com) -- To understand friction on a very small scale, a team of University of Wisconsin-Madison engineers had to think big. http://www.physorg.com/news154790620.html Nanotechnology Wed, 25 Feb 2009 13:24:33 EST news154790620 The ability of the Food and Drug Administration (FDA) to regulate the safety of dietary supplements using nanomaterials is severely limited by lack of information, lack of resources and the agency's lack of statutory authority in certain critical areas, according to a new expert report released by the Project on Emerging Nanotechnologies (PEN). http://www.physorg.com/news151160447.html Nanotechnology Wed, 14 Jan 2009 13:00:47 EST news151160447
