(PhysOrg.com) -- Nanoparticles combining platinum and gold act as superefficient catalysts, but chemists have struggled to create them in an industrially useful form. Rice University chemists have answered the call this week with a polymer-coated version of gold-platinum nanorods, the first catalysts of their kind that can be used in the organic solvents favored by chemical and drug manufacturers. http://www.physorg.com/news170946874.html Nanotechnology Mon, 31 Aug 2009 14:15:04 EST news170946874 In a paper published in the journal Nature Materials, EPFL professor Michael Graetzel, Shaik Zakeeruddin and colleagues from the Changchun Institute of Applied Chemistry at the Chinese Academy of Sciences have achieved a record light conversion efficiency of 8.2% in solvent-free dye-sensitized solar cells. http://www.physorg.com/news133964166.html Technology Sun, 29 Jun 2008 13:16:06 EST news133964166
