Nanosized and crystalline sp3-bonded carbon materials were prepared over large surface areas up to ~33x51 m2 from the exposure of few-layer graphene (FLG) to H radicals produced by the hot-filament process at low temperature ...

Hot-filament process was recently employed to convert, totally or partially, few-layer graphene (FLG) with Bernal stacking into crystalline sp3–C layers at low pressure. The result reported earlier relies on Raman spectroscopy ...
