Caltech-led team creates damage-tolerant metallic glass
— 13 Jan 2011 16:51 | TechnologyGlass is inherently strong, but when it cracks or otherwise fails, it proves brittle, shattering almost immediately. Steel and other metal alloys tend to be tough - they resist shattering…
Chemistry for greenhouse gases
— 30 Nov 2010 21:57 | ChemistryIf fossil fuels burn completely, the end products are carbon dioxide and water. Today the carbon dioxide is a waste product, one that goes into the air - adding to global warming; or…
New highly stable fuel-cell catalyst gets strength from its nano core
— 11 Nov 2010 12:02 | TechnologyStop-and-go driving can wear on your nerves, but it really does a number on the precious platinum that drives reactions in automotive fuel cells. Before large fleets of fuel-cell-powered…
Organic solvent system may improve catalyst recycling and create new nanomedicine uses
— 29 Oct 2010 13:24 | HealthNoble metals such as platinum and palladium are becoming increasingly important because of growth in environmentally friendly applications such as fuel cells and pollution control catalysts.…
Metal-mining bacteria are green chemists
— 2 Sep 2010 14:52 | BiologyMicrobes could soon be used to convert metallic wastes into high-value catalysts for generating clean energy, say scientists writing in the September issue of Microbiology…
MIT chemists find an easier way to synthesise new drug candidates
— 25 Jun 2010 11:17 | HealthSome drugs may be more effective the longer they last inside the body. To prevent such drugs from being broken down too rapidly, pharmaceutical manufacturers often attach a fluorine-containing…
