Making graphene powder useful in carbon-based electrical devices involves preparing graphene solution in which graphene particles are dispersed in a solvent; aggregating the particles; separating aggregated particles from solvent and drying.

Perforating graphene which is used as gas filters involves exposing a stream of gas into plasma to generate an activated gas stream; directing the gas stream toward a graphene sheet; and perforating the graphene sheet with the gas stream.

Deionizing solution involves functionalizing graphene sheet apertures to repel first ions in solution that also inhibits transit of second ions and passing solution by flow path to form deionized solution on solution flow path output side.

Deionizing fluid carrying unwanted ions involves applying pressurized fluid to first surface of perforated graphene in cylindrical form, so that fluid flows to second side of the sheet in preference to ions; and collecting the fluid.
