1. A process for production of nano-structures, comprising:

  • providing a graphite flake comprising graphene layers;

    intercalating the graphite flake to form a graphite intercalation compound exhibiting Stage I, II or III intercalation;

    exfoliating the graphite intercalation compound by exposing it to a temperature between about 1600°

    C. and about 2400°

    C., such that a plurality of individual graphene layers are separated from the graphite intercalation compound; and

    passing the plurality of individual graphene layers directly into a liquid,wherein the temperature between 1600°

    C. and 2400°

    C. is provided by a gas plasma.
