The breakthrough in this article is one of scaling, they can create uniform graphene sheets the size of a computer chip wafer. Other graphene applications often don't need regular graphene flakes, but chips do. They can now create chip sized flakes, exactly the size they need.
when one speaks of scaling, we do not mean in the laboratory. Scaling requires one to be able to repeatedly do the thing (yes at larger size) in a cost effective manner. Many times one can accomplish part of the goal (i.e. doing something repeatedly with proper quality) but not in a cost effective manner. that is why I said it is hopeful. We will see what additional work produces
