We report here a rapid, microwave-solvothermal synthesis of graphene nanosheets within few minutes at <300 °C without requiring highly toxic chemicals with strong reducing properties or reducing gas atmospheres at elevated temperatures. The graphene nanosheets produced are decorated with polyaniline nanocomposites and exhibit high charge storage capacity in lithium ion batteries and electrochemical capacitors.

A facile microwave-hydrothermal approach has been used to synthesize single-crystalline Fe(3)O(4) nanowires within 15 min at 150 degrees C. The Fe(3)O(4) nanowires, after decorating with carbon, exhibit excellent cyclability and rate performance when employed as an anode in lithium ion batteries.
