Single-layer graphene was first unambiguously produced and identified in 2004, by the group of Andre Geim and Konstantin Novoselov, though they credit Hanns-Peter Boehm and his co-workers for the experimental discovery of graphene in 1962; while it had been explored theoretically by P. R. Wallace in 1947.
In 2015, a coiled form of graphene was discovered in graphitic carbon (coal). The spiraling effect is produced by defects in the material's hexagonal grid that causes it to spiral along its edge, mimicking a Riemann surface, with the graphene surface approximately perpendicular to the axis. When voltage is applied to such a coil, current flows ...
The duo’s unique bond made world headlines and was ... TIL that Graphene is the thinnest two-dimensional material in existence and is 200 times stronger than steel. ... This discovery in 1972 ...
Graphene is an atomic-scale honeycomb lattice made of carbon atoms. Geim's achievements include the discovery of a simple method for isolating single atomic layers of graphite, known as graphene, in collaboration with researchers at the University of Manchester [36] and IMT. The team published their findings in October 2004 in Science.

Huang created the glass by accident whilst making graphene, when she found that her graphene was actually composed from silicon and oxygen, the elements that constitute glass. [4] [7] This accidental discovery made it possible to identify the arrangement of atoms in glass for first time, and was included in the Guinness World Records.
