(PhysOrg.com) -- Scientists at the U.S. Department of Energy`s Brookhaven National Laboratory have found a new way to use a synthetic form of DNA to control the assembly of nanoparticles - this time resulting in switchable, three-dimensional and small-cluster structures that might be useful, for example, as biosensors, in solar cells, and as new materials for data storage. The work is described in Nature Nanotechnology, published online December 20, 2009. http://www.physorg.com/news180624054.html Nanotechnology Mon, 21 Dec 2009 13:21:26 EST news180624054 (PhysOrg.com) -- If the promise of nanotechnology is to be fulfilled, nanoparticles will have to be able to make something of themselves. An important advance towards this goal has been achieved by researchers with the U.S. Department of Energy's Lawrence Berkeley National Laboratory who have found a simple and yet powerfully robust way to induce nanoparticles to assemble themselves into complex arrays. http://www.physorg.com/news175450958.html Nanotechnology Thu, 22 Oct 2009 17:23:20 EST news175450958 Cells could be orientated in a controlled way on a micro-patterned surface based upon a delicate material technique, and the orientation could be semi-quantitatively described by some statistical parameters, as suggested by the group of DING from Fudan University, Shanghai, CHINA. The study is reported in Issue 18, Volume 54 (September 2009) of the Chinese Science Bulletin as one of the papers in a special issue about Biomedical Materials in this journal. http://www.physorg.com/news174646818.html Biology Tue, 13 Oct 2009 10:10:04 EST news174646818 (PhysOrg.com) -- Today, scientists at IBM Research and the California Institute of Technology announced a scientific advancement that could be a major breakthrough in enabling the semiconductor industry to pack more power and speed into tiny computer chips, while making them more energy efficient and less expensive to manufacture. http://www.physorg.com/news169796309.html Nanotechnology Tue, 18 Aug 2009 06:39:11 EST news169796309 Scientists at the Technische Universitaet Muenchen (TUM) and Harvard University have thrown the lid off a new toolbox for building nanoscale structures out of DNA, with complex twisting and curving shapes. In the August 7 issue of the journal Science, they report a series of experiments in which they folded DNA, origami-like, into three dimensional objects including a beachball-shaped wireframe capsule just 50 nanometers in diameter. http://www.physorg.com/news168787205.html Nanotechnology Thu, 06 Aug 2009 14:20:42 EST news168787205 (PhysOrg.com) -- Visiting aliens may be the stuff of legend, but if a scientific team working at the National Institute of Standards and Technology is right, we may be able to find extraterrestrial life even before it leaves its home planet -by looking for left- (or right-) handed light. http://www.physorg.com/news159640612.html Physics Wed, 22 Apr 2009 17:37:25 EST news159640612 (PhysOrg.com) -- In order to save money and energy, many people are purchasing hybrid electric cars or installing solar panels on the roofs of their homes. But both have a problem -- the technology to store the electrical power and energy is inadequate. http://www.physorg.com/news156710943.html Nanotechnology Thu, 19 Mar 2009 19:50:01 EST news156710943 (PhysOrg.com) -- Recent research by scientists in Italy and France shows that that single molecules have the ability to store information via their magnetic state. Their work is a first step toward a new generation of ultra-compact data storage technologies based on individual molecules. http://www.physorg.com/news155820171.html Physics Mon, 09 Mar 2009 12:23:28 EST news155820171 HOUSTON -- (Feb. 5, 2009) -- Rice University materials scientists have put a new "twist" on carbon nanotube growth. The researchers found the highly touted nanomaterials grow like tiny molecular tapestries, woven from twisting, single-atom threads. http://www.physorg.com/news153060785.html Nanotechnology Thu, 05 Feb 2009 12:56:27 EST news153060785 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 (PhysOrg.com) -- From the structure of DNA to nautical rope to distant spiral galaxies, helical forms are as abundant as they are useful in nature and manufacturing alike. Researchers at the Harvard School of Engineering and Applied Sciences (SEAS) have discovered a way to synthesize and control the formation of nanobristles, akin to tiny hairs, into helical clusters and have further demonstrated the fabrication of such highly ordered clusters, built from similar coiled building blocks, over multiple scales and areas. http://www.physorg.com/news150646112.html Nanotechnology Thu, 08 Jan 2009 14:08:32 EST news150646112
