CANBERRA, Feb. 15 (Xinhua) – Australian researchers have developed a new method of purifying water which they say could save millions of lives.
Scientists from the Commonwealth Scientific and Industrial Research Organisation (CSIRO) have designed their own type of graphene, a form of carbon consisting of a single layer of carbon atoms in a lattice, named "GraphAir."
The new technology has made water purification quicker, more effective and simpler for the 2.1 billion people in the world who do not have access to clean drinking water.
