(PhysOrg.com) -- A new alternative energy technology relies on the element most associated with climate change: carbon. http://www.physorg.com/news175182633.html Nanotechnology Mon, 19 Oct 2009 14:52:08 EST news175182633 In a development that holds much promise for the future of solar cells made from nanocrystals, and the use of solar energy to produce clean and renewable liquid transportation fuels, researchers with the U.S. Department of Energy's Lawrence Berkeley National Laboratory have reported a technique by which the electrical conductivity of nanorod crystals of the semiconductor cadmium-selenide was increased 100,000 times. http://www.physorg.com/news171796742.html Nanotechnology Thu, 10 Sep 2009 10:19:35 EST news171796742 A team of scientists from Oregon State University has created the first global three-dimensional map of electrical conductivity in the Earth's mantle and their model suggests that that enhanced conductivity in certain areas of the mantle may signal the presence of water. http://www.physorg.com/news169906990.html Space & Earth Wed, 19 Aug 2009 13:23:46 EST news169906990 (PhysOrg.com) -- As organic light-emitting diodes (OLEDs) are poised to go mainstream in the near future, scientists continue to explore new twists on the technology. Recently, researchers have fabricated a "liquid-OLED" - an OLED that uses a liquid organic semiconducting layer to transport charge. http://www.physorg.com/news169466260.html Physics Fri, 14 Aug 2009 10:58:35 EST news169466260 (PhysOrg.com) -- Modelling the fabrication processes for integrated circuits can slash production development time and costs by up to 40%. But as transistors, already at nano-scales, become ever smaller, researchers are modelling new worlds. Over the past seven years, the microprocessors in everyday electronic equipment have delivered astonishing advances in speed while reducing power consumption per transistor. http://www.physorg.com/news169134954.html Technology Mon, 10 Aug 2009 15:10:01 EST news169134954 Customers want fresh food, which is neither unripe nor spoiled. A new system based on metal oxide sensors could check the safety and quality of foods reliably, quickly and economically -- such as how ripe that pineapple really is. http://www.physorg.com/news168525628.html Technology Mon, 03 Aug 2009 13:50:03 EST news168525628 (PhysOrg.com) -- With the whoosh of compressed gas and the whir of unspooling wire, a team of Boulder scientists and engineers tested a new instrument prototype that might be used to detect groundwater deep inside Mars. http://www.physorg.com/news165082774.html Space & Earth Wed, 24 Jun 2009 18:10:01 EST news165082774 Electronic devices of the future could be smaller, faster, more powerful and consume less energy because of a discovery by researchers at the Department of Energy's Oak Ridge National Laboratory. http://www.physorg.com/news164425018.html Nanotechnology Wed, 17 Jun 2009 04:10:01 EST news164425018 (PhysOrg.com) -- Millions of people today carry around pocket-sized music players capable of holding thousands of songs, thanks to the discovery 20 years ago of a phenomenon known as the `giant magnetoresistance effect,` which made it possible to pack more data onto smaller and smaller hard drives. Now scientists are on the trail of another phenomenon, called the `colossal magnetoresistance effect` (CMR) which is up to a thousand times more powerful and could trigger another revolution in computing technology. http://www.physorg.com/news163420444.html Physics Fri, 05 Jun 2009 11:35:06 EST news163420444 Dear EarthTalk: What is "nanotechnology"? I've heard that nanoparticles are already in consumer products, yet we haven't really studied their potential health impacts. (Dan Zeff, San Francisco) http://www.physorg.com/news162480951.html Nanotechnology Mon, 25 May 2009 14:38:25 EST news162480951 Kansas State University engineers think the possibilities are deep for a very thin material. http://www.physorg.com/news158850916.html Nanotechnology Mon, 13 Apr 2009 14:16:07 EST news158850916 A method for creating dispersed and chemically modified graphene sheets in a wide variety of organic solvents has been developed by a University of Texas at Austin engineering team led by Professor Rod Ruoff, opening the door to use graphene in a host of important materials and applications such as conductive films, polymer composites, ultracapacitors, batteries, paints, inks and plastic electronics. http://www.physorg.com/news157717683.html Nanotechnology Tue, 31 Mar 2009 11:28:34 EST news157717683 The Polymer Chemistry Research Group at the University of Helsinki, Finland, has succeeded in producing nano-sized metallic copper particles. When the size of particles is reduced to a nano-scale (one nanometre being one billionth of a metre), the properties of the material undergo substantial changes. Unlike in bulk materials, in nanoparticles the number of surface atoms is considerably greater than the number of atoms inside the material, which, among other things, makes the melting temperature of nanomaterials very low. With suitable heat treatment (sintering), the particles manufactured by the research group can be made to form electricity-conducting layers and patterns on paper. http://www.physorg.com/news156436057.html Nanotechnology Mon, 16 Mar 2009 15:28:21 EST news156436057 Geothermal energy is increasingly contributing to the power supply world wide. Iceland is world-leader in expanding development of geothermal utilization: in recent years the annual power supply here doubled to more than 500 MW alone in the supply of electricity. And also in Germany, a dynamic development is to be seen: over 100 MW of heat are currently being provided through geothermal energy. http://www.physorg.com/news154960844.html Space & Earth Fri, 27 Feb 2009 12:41:47 EST news154960844 Need to store electricity more efficiently? Put it behind bars. That's essentially the finding of a team of Rice University researchers who have created hybrid carbon nanotube metal oxide arrays as electrode material that may improve the performance of lithium-ion batteries. http://www.physorg.com/news153404774.html Nanotechnology Mon, 09 Feb 2009 12:27:24 EST news153404774 With gasoline at high prices, it's disheartening to know that up to three-quarters of the potential energy you are paying for is wasted. A good deal of it goes right out the tailpipe instead of powering your car. http://www.physorg.com/news142774576.html Chemistry Thu, 09 Oct 2008 12:36:16 EST news142774576
