The American Chemical Society said in 2012 that graphene was discovered to be 200 times stronger than steel and so thin that a single ounce of it could cover 28 football fields. Chinese scientists have created a graphene aerogel, an ultralight material derived from a gel, that is one-seventh the weight of air. A cubic inch of the material could balance on one blade of grass. "Graphene is one of the few materials in the world that is transparent, conductive and flexible — all at the same time," said Dr Aravind Vijayaraghavan, a lecturer in nanomaterials at the University of Manchester. "All of these properties together are extremely rare to find in one material."
So what do you do with graphene? Physicists and researchers say that we will soon be able to make electronics that are thinner, faster and cheaper than anything based on silicon, with the option of making them clear and flexible. Long-lasting batteries that can be submerged in water are another possibility In 2011, researchers at Northwestern University built a battery that incorporated graphene and silicon, which the university said could lead to a cellphone that "stayed charged for more than a week and recharged in just 15 minutes." In 2012, the American Chemical Society said that advancements in graphene were leading to touch-screen electronics that "could make cellphones as thin as a piece of paper and foldable enough to slip into a pocket."'
