Carbon Crafted Into Membranes
Water purification, seawater desalination, gas separations, and chemical filtrations could get a boost from two new carbon-based ultrathin membranes with unique properties: One selectively filters water, and the other selectively filters organic solvents, according to two reports in Science.
Rahul R. Nair, Andre K. Geim, and coworkers at the University of Manchester, in England, prepared graphene oxide laminates that are impermeable to liquids, vapors, and gases but allow water to pass . . .
