Research shows mechanism behind wear and tear, atom by atom

from University of Pennsylvania via Futurity

Scientists now have a clearer picture of how materials wear out at the nanoscale, which could help them design better parts for very tiny machines. Researchers at the University of Pennsylvania's School of Engineering and Applied Science have experimentally demonstrated one of the mechanisms behind wear at the smallest scale: the transfer of material, atom by atom, from one surface to another. more
