Graphene’s unique properties make it a potentially ideal membrane for water filtration or desalination. but the process of making it into ultrathin membranes creates leaky defects. So MIT engineers and associates have devised a two-step process to repair these leaks.
As shown in the illustration (top left) graphene is fabricated on a copper surface — a process that can create intrinsic defects in graphene. After lifting the graphene and… read more
