Graphene scroll
WebGraphene is a flat one-atom thick sheet of sp2 carbon atoms densely packed in a honeycomb crystal lattice structure. It is the basic structural element for graphite, carbon nanotubes, and fullerenes.Graphene samples are available as nanoflakes on Si / SiO 2 substrate wafers.Each layer is monoatomically thin with a thickness of ~0.34nm, though … WebThis is because a scroll can be manipulated and rotated more easily than a a sheet of graphene or graphite. However, the team was puzzled that while superlubricity was maintained in dry conditions, in a humid environment this was not the case. Because this behavior was counterintuitive, the team again turned to atomistic calculations.
