Graphene, the honeycomb-structured darling of materials, is now the world’s thinnest anticorrosion coating (ACS Nano, DOI: 10.1021/nn203507y). Researchers led by Vanderbilt University’s Kirill I. Bolotin report that with a coating of graphene just a few atoms thick, certain metals possess up to 20 times the corrosion resistance than they would have if they were bare. Graphene’s gossamer thinness makes it superior to polymeric coatings, which are relatively . . .
