After so many years (20?) of talk about graphene, and we haven't really seen any of the predictions come true. As far as I understand, it's because it's turned out to be really difficult to make it at an industrial scale. The article suggests that this new material is even harder to make. Is there any reason to believe this will actually have the impact that it was suggested graphene would, but never succeed at?
