Figure 1: Diagram of our experiments. We have demonstrated that an atomically thin sheet of graphene can be fabricated into a new structure—a trans-electrode membrane—that attracts cations and ...

Graphene, the wonder material that should rejuvenate almost every sphere of science and technology in the next decade or so, can add another application to its already exceedingly long list ...

Graphene, a single sheet of carbon atoms in a hexagonal lattice, has attracted great interest because of its exceptional electrical and optical properties 8,9,10,11,12,13. Graphene couples ...
