Scientists used high-power laser beams at the Department of Energy's SLAC National Accelerator Laboratory to simulate the shock effects of a meteorite impact in silica, one of the most abundant materials in the Earth's crust. They observed, for the first time, its shockingly fast transformation into the mineral stishovite -- a rare, extremely hard and dense form of silica.
8-Sep-2015 Making the most from carbon in plants
Researchers are looking for more effective ways to get at all the carbon in biomass to create more energy and biochemicals. However, a lot of the carbon is in lignin -- support tissues in plants, which makes up about a third of the biomass. International teams of scientists are utilizing EMSL's expertise and capabilities to better understand how lignin can be efficiently deconstructed to release its carbon for a more renewable and sustainable energy future.
3-Sep-2015 Researchers see 'spin current' in motion for the first time
Researchers at the Department of Energy's SLAC National Accelerator Laboratory have for the first time seen a spin current -- an inherent magnetic property common to all electrons -- as it travels across materials. The result, which revealed a surprising loss of current along the way, is an important step toward realizing a next-generation breed of electronics known as 'spintronics.'
