More than a century before graphene was isolated in a modern lab, Thomas Edison may have been unknowingly making the wonder ...

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.

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 ...

Transparent electrodes transmit light while conducting electricity and are increasingly important in bioelectronic and ...

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 ...

When Thomas Alva Edison was painstakingly testing carbonized filaments for his early light bulbs in 1879, he was chasing a ...

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 ...

Vertical graphene microstructures break the thickness-performance tradeoff in thermoacoustic speakers, enabling flexible ...

Graphene is often regarded as one of the strongest known materials. It is about 200 times stronger than steel while remaining exceptionally lightweight and flexible. 1 Despite these advantages, ...

The ever-shrinking features of transistors etched in silicon have always required pushing the cutting edge of manufacturing technology. The discovery of atomically thin materials like graphene and ...

Originating as a theoretical prediction in the 1940s, with experimental isolation from graphite in 2004, graphene has quickly become a desirable quantum material used in various application areas, ...
