(Phys.org) —Although scientists continue to discover the remarkable electronic properties of nanomaterials such as graphene and transition metal dichalcogenides, the way that electric current flows at this scale is not ...
Superconductors are the holy grail of energy efficiency. These mind-boggling materials allow electric current to flow freely without resistance. But that generally only happens at temperatures within a few degrees of absolute ...
