Researchers at the University of California, Riverside have created in the laboratory a class of carbenes, highly reactive molecules, used to make catalysts - substances that facilitate chemical reactions. Until now, chemists believed these carbenes, called "abnormal N-heterocyclic carbenes" or aNHCs, were impossible to make. http://www.physorg.com/news175440301.html Chemistry Thu, 22 Oct 2009 14:25:41 EST news175440301 (PhysOrg.com) -- A team of MIT chemists has devised a new way to add fluorine to a variety of compounds used in many drugs and agricultural chemicals, an advance that could offer more flexibility and potential cost-savings in designing new drugs. http://www.physorg.com/news169391963.html Chemistry Thu, 13 Aug 2009 14:50:03 EST news169391963 Nanyang Technological University (NTU)'s Associate Professor Zhong Guofu has made a significant contribution to the field of organic chemistry, in particular the study of using small organic molecules as catalysts, in the synthesis process called organocatalysis. Such synthesis process takes place for example, during the production of chiral drugs. http://www.physorg.com/news166266981.html Chemistry Wed, 08 Jul 2009 10:18:29 EST news166266981 Researchers at the University of Amsterdam (UvA) have succeeded in making the first ever piece of chiral palladium metal. The findings, by a research team led by Gadi Rothenberg, professor of Heterogeneous Catalysis and Sustainable Chemistry at the UvA, are significant because they lead to an entirely new class of materials. These are metallo-organics - they combine the variety of organic molecules with the special properties of metals. The research results are published this week in Nature Chemistry. http://www.physorg.com/news159686508.html Chemistry Thu, 23 Apr 2009 06:22:23 EST news159686508 (PhysOrg.com) -- A University of Toronto research team from the Department of Chemistry has discovered useful "green" catalysts made from iron that might replace the much more expensive and toxic platinum metals typically used in industrial chemical processes to produce drugs, fragrances and flavours. http://www.physorg.com/news158856665.html Chemistry Mon, 13 Apr 2009 15:51:40 EST news158856665 Even small devices need power, and much of that juice comes from fuel cells. As these devices become even smaller, the rush is on to find more efficient ways to power them. http://www.physorg.com/news156681586.html Nanotechnology Thu, 19 Mar 2009 11:40:13 EST news156681586 Hydrogen peroxide is one of the world's most versatile and widely used chemicals. A powerful oxidizing agent, H2O2 is commonly used as a bleach, an antiseptic and a disinfectant. http://www.physorg.com/news154276303.html Nanotechnology Thu, 19 Feb 2009 14:37:52 EST news154276303 The painstaking process of detecting toxic species of platinum and palladium mixed in with the form of platinum essential to certain pharmaceuticals could be reduced to one simple step, University of Pittsburgh researchers report in the Nov. 14 online edition of the Journal of the American Chemical Society (JACS). http://www.physorg.com/news145892668.html Chemistry Fri, 14 Nov 2008 13:44:28 EST news145892668
