The Chinese scientist Prof. Gao Chao of Department of Polymer Science and Engineering, Zhejiang University and team invented the world's ever lightest material which might have a good role in pollution control and purification. It has a mass of 0.16 milligram, according to the Scientists which is less denser than air. The previous record holder is an aerographite. The new material is 12 percent lighter than the previous one. It was made up of graphene which is a lightest compound of carbon. Aerogel is a low-density solid-state material derived from gel in which the liquid component of the gel has been replaced with gas. The result is an extremely low density solid with several remarkable properties.
