Material 200 times tougher than steel made using cooking oil
Australia-based scientists have used soybean oil to create graphene, a material 200 times stronger than steel. The technology 'GraphAir' involves heating soybean oil to decompose it into carbon building blocks which were cooled into a graphene film, thinner than a human hair. Even leftover cooking oil could be used for this which would drastically reduce its price, said the lead.
