Strength of Graphene

Caption

Engineers had thought that sheet of graphene that are joined together would have weakneses at the point of attachment. In some cases, however, the area where two sheets of graphene are joined can be as strong as pure graphene. Vivek Shenoy, with graduate student Rassin Grantab, illustrates the carbon heptagons that mark these “grain boundaries.”
