Researchers at the Cavendish Laboratory, University of Cambridge have demonstrated a new way to control radiation in the terahertz range—an often-overlooked part of the electromagnetic spectrum—with ...

Graphene capacitors are both highly flexible and have an energy density far beyond existing electrochemical capacitors, possibly within reach of conventional lithium-ion and nickel metal hydride ...

Materials engineers at Monash University in Australia have devised a method of producing graphene supercapacitors that have the same energy density as the lead-acid battery under your car's hood. Not ...
