Anyone who has seen pictures of the giant, red-hot cauldrons in which steel is made—fed by vast amounts of carbon, and belching flame and smoke—would not be surprised to learn that steelmaking is one of the world's leading industrial sources of greenhouse gases. But remarkably, a new process developed by MIT researchers could change all that. http://phys.org/news287237532.html Chemistry Wed, 08 May 2013 13:12:20 EST news287237532 (Phys.org) —XG Sciences (XGS) this month announced new anode materials for lithium-ion batteries. These will be viewed with interest among those watching the battery marketplace, where any promising news on battery breakthroughs is always welcome. XG Sciences said it has a new battery anode that is four times the capacity of conventional material—that is, anode materials for lithium-ion batteries with four times the capacity of conventional anodes. The anode material uses xGnP graphene nanoplatelets to stabilize silicon particles in a nano-engineered composite structure. XG Sciences makes these nanoplatelets through techniques that allow for control of their size and surface characteristics. Graphene anode material, when combined with xGnP graphene products as conductive additives, provides higher energy storage than do conventional battery materials, according to the company. http://phys.org/news285048447.html Technology Sat, 13 Apr 2013 07:10:01 EST news285048447 An assistant professor at the University of California, Riverside's Bourns College of Engineering has recently received a $360,000 grant to better organize enzymes on electrodes to create nanoscale devices that more efficiently convert the chemical energy of sugars and complex carbohydrates in to electricity. http://phys.org/news281890461.html Chemistry Thu, 07 Mar 2013 14:54:26 EST news281890461 (Phys.org)—Looking toward improved batteries for charging electric cars and storing energy from renewable but intermittent solar and wind, scientists at Oak Ridge National Laboratory have developed the first high-performance, nanostructured solid electrolyte for more energy-dense lithium ion batteries. http://phys.org/news278183615.html Nanotechnology Wed, 23 Jan 2013 17:14:25 EST news278183615 (Phys.org)—When Ovadia Lev, Professor of Environmental Chemistry and Health at The Hebrew University of Jerusalem, and his research team developed a new coating technology a few years ago, they thought it was an interesting outcome of their research in hydrogen peroxide solutions. However, they weren't sure what to do with it until they met a team of researchers looking for a simple way to synthesize new lithium-ion battery anode materials, such as graphene-tin oxide composites. http://phys.org/news272180935.html Nanotechnology Thu, 15 Nov 2012 08:50:01 EST news272180935 (Phys.org) -- Researchers in the United Kingdom have taken another step towards proving that so named lithium-air (Li-O2) batteries might one day become practical. Up to now the problem has been using the technology to build a battery that uses oxygen and that can survive many charge-discharge-recharge cycles. Now Zhangquan Peng, Stefan Freunberger, Yuhui Chen and Peter Bruce of Saint Andrews in Scotland, have developed a way to build a lithium-air battery, using a gold electrode that, as they describe in their paper published in the journal Science, survived a hundred cycles with just 5% loss of power. http://phys.org/news261992988.html Technology Fri, 20 Jul 2012 09:02:29 EST news261992988 (Phys.org) -- Researchers at Rice University and Lockheed Martin reported this month that they've found a way to make multiple high-performance anodes from a single silicon wafer. The process uses simple silicon to replace graphite as an element in rechargeable lithium-ion batteries, laying the groundwork for longer-lasting, more powerful batteries for such applications as commercial electronics and electric vehicles. http://phys.org/news261674060.html Chemistry Mon, 16 Jul 2012 16:14:38 EST news261674060 Researchers from the NIST Center for Nanoscale Science and Technology and Arizona State University have used environmental transmission electron microscopy (ETEM) to explain the role of nickel nanoparticles in lowering the operating temperature of praseodymium doped ceria (PDC) anodes in solid-oxide fuel cells (SOFCs).  http://phys.org/news253349741.html Chemistry Wed, 11 Apr 2012 07:57:20 EST news253349741 (PhysOrg.com) -- By wrapping tiny sulfur particles in graphene sheets, researchers from Stanford University have synthesized a promising cathode material for rechargeable lithium-sulfur batteries that could be used for powering electric vehicles on a large scale. When combined with silicon-based anodes, the new graphene-sulfur cathodes could lead to rechargeable batteries with a significantly higher energy density than is currently possible. http://phys.org/news229748015.html Nanotechnology Wed, 13 Jul 2011 08:20:01 EST news229748015 NEC Corporation announced today the development of a thin and flexible Organic Radical Battery (ORB) that is significantly more reliable and produces 1.4 times more output than existing units. http://phys.org/news208512352.html Technology Tue, 09 Nov 2010 08:06:22 EST news208512352 (PhysOrg.com) -- A barrier coating developed through CSIRO’s Light Metals Flagship offers aluminium smelters significant annual savings in reduced consumption of petroleum coke alone. http://phys.org/news154620422.html Technology Mon, 23 Feb 2009 14:07:44 EST news154620422
