Great educational stuff Nasa, a revolution is upon us! It is a concern to me though, that as the youtube says, 'a football field sized sheet of graphene weighs less than a gram', where's the profit in that?
Yes, there are many and varied applications for the product and different levels of purity are required for different applications etc etc. This all has me wondering how FGR vein can be totally dominant over other producers of lower purity graphite? where is FGR to be positioned in the supply of graphene. The costs of raising the purity of graphite are not huge v the return of supplying graphene.
