(color online) Images of different ultrasonically-treated graphene oxide membranes. The Petri dishes on the left-hand side contain the low temperature membranes and the Petri dishes on the right-hand side contain the high temperature membranes. Panel (a) is for the initial state, panel (b) the state after a 5-min ultrasonication treatment, and panel (c) the state after a 10-min ultrasonication treatment.
