© 2008 Science
Scientists have long suspected that graphene—chicken wire-like, two-
dimensional sheets of carbon—is the strongest material ever examined. Now,
that's been verified by mechanical engineering professor James Hone of
Columbia University and colleagues (Science 2008, 321, 385). The task has
been difficult because the slightest impurity or defect greatly affects a
material's intrinsic strength. Scientists have in the past attempted to
