In addition graphene membranes could be used to sieve hydrogen gas out of the atmosphere where it is present in minute quantities,
"The flux through the current graphene membranes was at least an order of magnitude higher than that through state-of-the-art reverse osmosis polymeric membranes."
Meni Wanunu, an assistant professor of physics at Northeastern University, says the group work with graphene membranes may significantly improve on commercial membranes used for water purification,
it is only through a fundamental understanding of ion transport that the overall anticipated behaviors of bulk graphene membranes can be drawn.
Graphene membranes are also more efficient, converting over 99 percent of the energy driving the device into sound,
