There’s a new ‘world’s lightest material’ – graphene aerogel

aerogel_grapheneResearchers have managed to make an aerogel-like material using carbon nanotubes and graphene as the underlying support structure, with the result being an incredible light, elastic, sponge-like material.  With a density of only .16mg/cm^3, it’s incredibly elastic and can absorb 68 times its weight in organic compounds per second (important if, for example, this finds a use in containing oil spills).  Apart from that, I’m not really sure what the possible uses are, but it’s cool to see technology being used to make new materials like this.
