But that wasn't known until 2004, when Geim and Novoselov, both of of the University of Manchester, UK, first used sticky tape to pull tiny sheets of carbon off a piece of graphite.

It was pointed out that the breaking strain was an important index to describe the properties of carbon materials, especially graphite electrodes, because the criterion resisting thermal shock was direct proportion to it.
