A one-pot procedure converts solutions of graphene oxide and precursor ions to crumpled sheets of graphene decorated with nanocrystals, according to a study led by researchers at the University of Wisconsin, Milwaukee (ACS Nano, DOI: 10.1021/nn302818j). The method builds on work reported recently by other scientists that shows graphene sheets can be crumpled into nanosized balls that resist uncrumpling, aggregating, and . . .
