Graphene has been a wonder material ever since it was first isolated in 2004. A graphene sheet, one carbon atom thick, is strong, lightweight and highly conductive, and researchers have been ...

there is no doubt that graphene, a single layer of carbon atoms densely packed into a benzene-ring structure, is an excellent playground for condensed-matter physicists and materials scientists.

one is the preparation of graphene-based nanomaterials with well-defined structures, and the other is the controllable fabrication of these materials into functional devices. Schematic models of ...
