Let's drop the little one?While reading "Gripping Tale: Metal oozes in nanotubes' grasp" (SN: 5/27/06, p. 326), I pondered what would happen if fissionable fis·sion·a·ble adj. Capable of undergoing fission: fissionable nuclear material. fis elements were the core crystals of the nanosqueeze. Would nanoreactors or nanobombs be possible? VICTOR LAWNICKI, LOUISVILLE, KY.

Accidentally discovered by a Japanese researcher at NEC in 1990 while making Buckyballs, they have potential use in many applications. . |
