Graphene supercapacitors are moving from lab curiosity to serious contender for the next wave of electric vehicle energy storage. By pairing the near-instant charging of capacitors with the high ...

Taking advantage of quantum mechanical effects can be an alternative method for modifying current in high-sensitivity nanoscale devices.

A sheet of graphene sandwiched between electrolytes can host independently tunable proton and electron currents — setting the stage for a device that serves both computer-memory and logic functions.

Identical growth conditions yield uniform monolayer graphene on three different perovskite oxides, suggesting gas-phase ...

Graphene sheets with 5- or 7-membered rings form cone or saddle shapes, affecting curvature and rigidity. A new method helps study their complex mechanics. (Nanowerk News) Graphene sheets (GS) are two ...

Researchers have created the first functional semiconductor made from graphene, a single sheet of carbon atoms held together by the strongest bonds known. The breakthrough throws open the door to a ...

Carbon capture is becoming essential for industries that still depend on fossil fuels, including the cement and steel ...

The number of graphene layers determines specific properties. Both single-layer and bi-layer graphenes are zero band gap semiconductors because of the association between conduction and the valance ...

By using mechanical force and a common amino acid, researchers have demonstrated a way to make graphene both electrically ...
