Thank you, Sai...

Sanosh Padmanabhan Kunjalukkal

you can make it from Commercially-available expandable graphite ﬂakes (GIC), whic is intercalated with a mixture of sulfuric acid and nitric acid . This mixture has to heated at 700 (EG) flakes. These EG ﬂakes sonicated in acetone and dried in air leading to expanded and sonicated graphene stacks.

Thank you, Sanosh.
