“Pour Cleanser” — The Discovery Files

University of Illinois professor Narayana Aluru led a team that found that tiny pores in thin sheets of the material molybdenum disulfide could be very good at removing salt from seawater to yield drinkable water. The material, a nanometer-thick sheet of molybdenum disulfide (MoS2) riddled with tiny holes called nanopores, is specially designed to let high volumes of water through but keep salt and other contaminates out, a process called desalination.
