What is graphene?
Graphene – a single layer of carbon atoms – may be the most amazing and versatile substance available to mankind.
(Graphene Flagship, 2013)
Graphene is a 2-dimensional, crystaline allotrope of carbon. [..]
High-quality graphene is strong, light, nearly transparent and an excellent conductor of heat and electricity. [..]
The combination of familiarity, extraordinary properties and surprising ease of isolation enabled a rapid increase in graphene research.
