graphene
graphene,
virtually transparent, highly conductive carbon material in which the atoms are organized into a honeycomblike arrangement and form a thin sheet that is one atom thick.

He was a professor at the Univ. of Nijmegen in the Netherlands from 1994 to 2001, when he joined the faculty at the Univ. of Manchester, England.

The structure and properties of graphene make it suitable for a broad range of applications, and it is being investigated for possible use in such products as smart displays, ultrafast transistors, tough composites, and quantum-dot computers. Some of the material's unique properties—electrons move through graphene like massless waves—also have allowed physicists to use simple benchtop laboratory equipment, rather than expensive telescopes and particle accelerators, to test quantum mechanical predictions, and it has been used to contain liquids for for study with electron microscopes.

Extraordinary Properties
Graphene's mechanical, electrical, optical, thermal and chemical properties are outstanding, and it has been touted as a "miracle material." The 2D sheets can be layered together, fabricated into wires (nanoribbons), flakes, disk-shaped platelets or quantum dots for many applications. In addition, graphene can be added to metals, ceramics, plastics and rubber to make products stronger, lighter, more heat resistant or more flexible.
As the most conductive material on the planet, in time, graphene is expected to supplant silicon in electronics fabrication; however, hurdles must be overcome. For example, graphene has no bandgap; the most essential semiconductor attribute. See bandgap.
Graphene is expected to be a foundation nanotechnology component that revolutionizes industries and future products. See nanotube and nanotechnology.
