Pencil full of lead

What does the smart phone and the pencil have in common?
Serious question.
Try and guess before scanning down and looking at the answer.















The answer is Graphine.
This atom sized material is part of the construction of graphite, which forms the lead in a pencil.
Graphine, which is probably the strongest material in the world, is used in the touch screen of smart phones etc.
It also allows electricity to flow through it at amazingly fast speeds.
The properties of it was discovered by Andre Geim in 2004. This humorous ex Soviet Union citizen won the Nobel prize for physics for his work with Graphine.

He also won the Ignobel prize for levitating a frog.
