Oak Ridge National Laboratory researchers have directly written high-purity metallic structures narrower than a cold virus—which could open nanofabrication opportunities in electronics, drug delivery, catalysis and chemical separations.
Material surfaces and interfaces may appear flat and void of texture to the naked eye, but a view from the nanoscale reveals an intricate tapestry of atomic patterns that control the reactions between the material and its environment.
Diesel vehicles today emit far fewer pollutants than older vehicles, thanks to a zeolite (hydrous silicate) catalytic converter that was invented around 10 years ago to reduce pollutants that cause the formation of acid rain and smog.
Five researchers at the Department of Energy’s Oak Ridge National Laboratory have been elected fellows of the American Association for the Advancement of Science (AAAS). AAAS, the world’s largest multidisciplinary scientific society
