Scientists in Erlangen have managed to produce graphene in large quantities with the help of soap and ultrasound. Graphene is the thinnest material known to us. It's transparent and harder than diamond. The ultra-thin carbon layer is an excellent conductor of electricity and heat.
Its properties have opened up a whole set of new industrial applications - like the mobile phone you can wrap around your arm, or a carbon-based computer. It also offers possibilities for making stable and highly conducting plastics.
