Composition, useful for removing carbonization catalyst to manufacture graphene sheet that is transferred onto substrate during manufacturing of e.g. solar cell, comprises acid and oxidizing agent.

NA D H

Membrane used to separate compound from fluid mixture, comprises graphene monolayer including discrete pores that are chemically perforated, where each pore has uniform pore size with carbon vacancy defects in the monolayer.

DUERKSEN G L, MILLER S A

Membrane used to separate gas from fluid mixture including first gas e.g. neon and second gas, includes graphene layer perforated by nanoscale pores, and gas sorbent to contact surface of layer and direct gas adsorbed at sorbent into pores.

Making graphene layers comprises preparing aqueous suspension of graphite oxide, filtering suspension through polymer filter leading to deposition of graphite oxide nanoparticles on filter surface and forming thin layer of graphite oxide.

BARKAUSKAS J

Graphene/aromatic polyamide hybrid reverse osmosis membrane preparation involves impregnating porous support membrane in aqueous phase medium, and contacting surface of porous support membrane with the oil phase medium.

WANG T, DU C, WU L

Preparation of graphene oxide porous film used for separating molecule or particle by mixing graphene oxide dispersion liquid and copper hydroxide nanowire solution, vacuum filtering, and adding acid solution.

PENG X, HUANG H

Separation membrane used in e.g. sea-water desalination apparatus and gas separation apparatus, comprises polymer support e.g. polysulfone and graphene (containing grains defined by grain boundaries) on the polymer support.
