We have also synthesized reduced graphene oxide and partially rolled graphene by this method. Keywords: electric discharges; microwave synthesis; nanomaterials; transmission electron

• microwaves [12][13][14]. It was found that the sintering of metal powders by microwaves produces products that are denser than and mechanically superior to the ones obtained by conventional heating [14]. Other than reflection and conduction, metal particles usually produce electric discharges (arcs) when
