(PhysOrg.com) -- Similar to the way pavement, softened by a hot sun, will slow down a car, graphenea one-atom-thick sheet of carbon with wondrous propertiesslows down an object sliding across its surface. But stack the sheets and graphene gets more slippery, say theorists at the National Institute of Standards and Technology, who developed new software to quantify the material's friction.
