This method combines reactions and separation processes, does not produce chemical waste and uses much less energy. http://www.chemlin.net/news/2006/dec2006/chemical-industry.htm Wed, 6 Dec 2006 02:44:53 GMT Tiny formless particles in water solution take on a well-ordered and functional structure as soon as they come into contact with nanoparticles of silica... http://www.chemlin.net/news/2006/dec2006/silica-particle.htm Tue, 5 Dec 2006 13:24:11 GMT Researchers have shown that, under the right circumstances, hydrogen can form multicenter bonds, where one hydrogen atom simultaneously bonds to as many as four or six other atoms... http://www.chemlin.net/news/2006/dec2006/hydrogen.htm Tue, 5 Dec 2006 13:23:04 GMT It may look like mistletoe wrapped around a flexible candy cane. But this molecular model shows how some proteins form loops in DNA when they chemically attach, or bind, at separate sites to the double-helical molecule that carries life’s genetic blueprint. http://www.chemlin.net/news/2006/dec2006/dna-loop.htm Tue, 5 Dec 2006 20:11:44 GMT New structures that reveal another critical piece of the puzzle: how the so-called polymerase II enzyme discriminates among potential RNA building blocks to ensure the characteristic accuracy of the process. http://www.chemlin.net/news/2006/dec2006/dna-transcribing.htm Fri, 1 Dec 2006 14:58:10 GMT Answering a question that has lingered for centuries, a team of scientists has proved that chemicals used to treat the wood used in Stradivarius and Guarneri violins are the reasons for the distinct sound produced by the world-famous instruments ... http://www.chemlin.net/news/2006/dec2006/stradivarius-violins.htm Fri, 1 Dec 2006 14:59:59 GMT
