As a material scientist, I'm reminded of a joke from college which has changed only a little: What's the only thing graphene (used to be carbon nanotubes) can't do?
A: Leave the lab
Hopefully this news triggers a wave of new investment built on hype with a few companies that actually succeed, enabling another platform for even more new innovations.
``` The capability to control graphene layer properties defines its usefulness for the desired application. Whether this be physical (mechanical strength, porosity, thickness of stacked layers), electrical (conductivity, carrier density, band gap availability) or otherwise (thermal conductivity, transparency, flexibility). ```
