A team of researchers at MIT, Oak Ridge National Laboratory, and in Saudi Arabia succeeded in creating subnanoscale pores in a sheet of graphene, a development that could lead to ultrathin filters for improved desalination or water purification. Their findings are published in the journal Nano Letters.The new work, led by graduate student Sean O’Hern and associate professor of mechanical engineering Rohit Karnik, is the first step toward actual production of such a graphene filter.
