Caption: A pre-cracked sheet of graphene was suspended and pulled apart on a spring-loaded stage to measure how much strength a defective piece of graphene shows. Scientists at Rice University and Georgia Tech found graphene is only as strong as its weakest point. Because most graphene has defects, its real strength is likely to be significantly lower than the intrinsic strength of a perfect sheet of the atom-thick carbon material.
