Graphene Mass Production, Roll to Roll

Graphene, the lightest and thinnest compound known to man at one atom thick, has many amazing and unique properties that make it a very interesting candidate for many futuristic applications. However, its use is presently limited due to a bottleneck in its synthesis and mass production, which are st...
