Jewelers, geologists, and microscopists agree: diamonds are forever. Researchers at the University of Illinois Urbana-Champaign are using microscopic nanodiamonds to calibrate and assess the performance of high-powered microscopes. Their longevity and durability make the tiny “first-aid kits” more than up to the task.
