Why UK is investing in 'miracle material' graphene
The UK government has pledged £50m towards developing spin-off technologies from the super-strong material graphene.
The announcement comes one year after two Manchester-based scientists were awarded the Nobel-prize for its discovery.
Graphene, the "miracle material" of the 21st Century, is so far the strongest material known to science, and is better at conducting electricity than copper.
