Engineering researchers demonstrate that graphene, even if stitched together from many small crystalline grains, is almost as strong as graphene in its perfect crystalline form. This resolves a contradiction between theoretical simulations, which predicted grain boundaries can be strong, and earlier experiments, which indicated they were much weaker than the perfect lattice.
