NRI Scientist discovers material to make seawater drinkable

INITIAnaluA team of researchers, led by Narayana Aluru, professor at University of Illinois, has discovered a nanometre-thick sheet of molybdenum disulfide, riddled with tiny nanopores that is designed to let high volumes of water through, but keep salt and other contaminants out.The material aka MoS2 showed great efficiency filtering through up to 70% more water than graphene membranes.

Most desalination technologies rely on reverse osmosis to push seawater through a fine plastic membrane to make fresh water but the yield is very small.

In this case using the Blue Waters supercomputer the researchers found that a single layer of MoS2 has the advantages of thinness, requiring much less energy, that dramatically reduces operating costs.
