Nanotube Applications Grow And Grow

These apps include non-volatile RAM, flat screen displays, high strength fabrics, and smart skin for structures in aerospace and elsewhere. Perhaps if The Graduate was being made today, the one word for Benjamin Braddock's future would not be "plastics" but "nanotubes"."
