We describe a new and highly efficient plasma-assisted electrochemical exfoliation method, involving a plasma-generated graphite cathode and a graphite anode, for the production of graphene sheets from electrodes in a basic electrolyte solution in a short reaction time.

We demonstrate an efficient method for the production of few-layer MoS2 nanosheets through exfoliation of bulk MoS2 compounds that were subject to quenching in liquid N-2 and subsequent ultrasonication. This solution- based method, which involves a "quenching cracks" phenomenon, was performed open to the atmosphere. Subsequent ultrasonication of the exfoliated MoS2 in solution provided us with MoS2 nanosheets comprising two to four layers.
