Size Matters as Nanocrystals Go Through Phases
Berkeley CA (SPX) Sep 10, 2013
Understanding what happens to a material as it undergoes phase transformations - changes from a solid to a liquid to a gas or a plasma - is of fundamental scientific interest and critical for optimizing commercial applications. For metal nanocrystals, assumptions about the size-dependence of phase transformations were made that now need to be re-evaluated. A team of researchers at the U.S. Department of Energy (DOE)'s Lawrence Berkeley National Laboratory (Berkeley Lab) has demonstrated that as me ... read more
