Graphene Illustration

Caption: New work by theorists at Rice and Tsinghua universities shows defects in polycrystalline forms of graphene will sap its strength. The illustration from a simulation at left shows a junction of grain boundaries where three domains of graphene meet with a strained bond in the center. At right is the calculated stress buildup at the tip of a finite-length grain boundary.
