A surge in research into the novel material graphene reveals an intensifying global contest to lead a potential industrial revolution.
Graphene is a flat sheet of carbon, one-atom thick and is almost completely transparent as well as being a good conductor of electricity.
Latest figures show a sharp rise in patents filed to claim rights over different aspects of graphene since 2007, with a further spike last year.
The BBC's science editor, David Shukman has a special report.
