Researchers `stretch` the ability of 2-D materials to change technology
(PHYSorg.com Nanotechnology)

Two-dimensional (2-D) materials-as thin as a single layer of atoms-have intrigued scientists with their flexibility, elasticity, and unique electronic properties, as first discovered in materials such as graphene in 2004. Some of these materials can be especially susceptible to changes in their material properties as they are stretched and pulled. Under applied strain, they have been predicted to undergo phase transitions as disparate as superconducting in one moment to nonconducting the next, or optically opaque in one moment to transparent in the next.
