New Process can Change Two-Layer Graphene into Diamond-Hard Material on Impact

Visualize a material as lightweight and flexible as foil that turns hard and stiff enough to stop a bullet on impact. In a recently published paper in Nature Nanotechnology, researchers across The City University of New York (CUNY) report a process for making diamene: flexible, layered sheets of graphene that become harder than diamond and impenetrable upon impact on a temporary basis.
