Porous, 3-D forms of graphene 10 times as strong as steel but much lighter

Researchers have designed one of the strongest lightweight materials known, by compressing and fusing flakes of graphene, a two-dimensional form of carbon. The new material, a sponge-like configuration with a density of just 5 percent, can have a strength 10 times that of steel.
