  • Perfect Imperfections Graphene is composed of six-atom rings, but will include a number of five- and seven-atom rings as defects. Using simulations, Grantab et al. (p. 946) show that more defects do not necessarily lead to greater deterioration of mechanical properties. Mismatches caused by differences in the orientation of neighboring crystals are divided into low- and high-angle grain boundaries, and typically it is the lower-angle boundaries that are stronger. In graphene, by contrast, the… CONTINUE READING
