Columbia researchers find graphene can't cope with stress

Graphene, a one-atom-thick layer of carbon, is considered the strongest material known to mankind. It has found countless applications in the field of nanotechnology, including the manufacturing of stronger-than-steel-by-a-hundredfold nanotubes. However, Assistant Professor Chris Marianetti at Columbia University has exposed a fundamental structural weakness of graphene that leads to its possible mechanical failure under strain, and could change the way we use this and other materials to build nanotech devices.
