Has the band gap issue been worked out?

I just read through their website, they claim it has, using the heading 'configurable':

``` 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). ```
