The National Institute of Standards and Technology has developed a free, online collection of data on the properties of gas hydrates, naturally occurring crystalline materials that are a potential energy resource and also may affect the Earth's climate. http://www.physorg.com/news174140874.html Chemistry Wed, 07 Oct 2009 14:00:02 EST news174140874 (PhysOrg.com) -- Cornell researcher Derek Stewart and collaborators have calculated the exact mechanism by which diamond conducts heat, a breakthrough that could lend insight into many fields, including electronics. http://www.physorg.com/news172850785.html Physics Tue, 22 Sep 2009 15:10:43 EST news172850785 (PhysOrg.com) -- Tomorrow's lasers may come with a bit of bling, thanks to a new technology that uses man-made diamonds to enhance the power and capabilities of lasers. Researchers in Australia have now demonstrated the first laser built with diamonds that has comparable efficiency to lasers built with other materials. http://www.physorg.com/news172497349.html Physics Fri, 18 Sep 2009 12:56:20 EST news172497349 (PhysOrg.com) -- Recent research into the properties of graphene nanoribbons provides two new reasons for using the material as interconnects in future computer chips. In widths as narrow as 16 nanometers, graphene has a current carrying capacity approximately a thousand times greater than copper -while providing improved thermal conductivity. http://www.physorg.com/news168103210.html Nanotechnology Wed, 29 Jul 2009 16:21:00 EST news168103210 (PhysOrg.com) -- Open any computer and you're sure to see at least one massive cooling device, complete with metal fins and a noisy fan. Today's high-power processing chips generate lots of heat -- and those chips can fry quickly without some serious cooling. http://www.physorg.com/news166374500.html Chemistry Thu, 09 Jul 2009 16:08:54 EST news166374500 The unique properties of thin layers of graphite - known as graphene - make the material attractive for a wide range of potential electronic devices. Researchers have now experimentally demonstrated the potential for another graphene application: replacing copper for interconnects in future generations of integrated circuits. http://www.physorg.com/news163344686.html Nanotechnology Thu, 04 Jun 2009 14:34:53 EST news163344686 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 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 In the past few years, the design and manufacturing of circuits at nanoscopic scale for integrated devices has become one of the frontier fields in new material science and technology. The significant reduction achieved in these devices often is accompanied by new discoveries in how they behave precisely when the systems are of extremely small dimensions. Understanding this new physics at nanoscopic scale at the same time has enabled researchers to study the possibility of designing new materials with innovative characteristics. http://www.physorg.com/news142677353.html Nanotechnology Wed, 08 Oct 2008 09:35:53 EST news142677353 Thermoelectric materials can be assembled into units, which can transform the thermal difference to electrical energy or vice versa - electrical current to cooling. An effective utilization requires however that the material supplies a high voltage and has good electrical, but low thermal conductivity. http://www.physorg.com/news142609332.html Nanotechnology Tue, 07 Oct 2008 14:42:12 EST news142609332 In a high-temperature blaze, how well does a fireproofing material shield a building`s important steel structures from heat? Answering this question has been surprisingly difficult, but it is important information for builders selecting high-performance fire-resistive materials and for scientists conducting computer simulations that investigate fires. http://www.physorg.com/news142166256.html Technology Thu, 02 Oct 2008 11:37:36 EST news142166256
