Pumping Carbon: Researchers watch nanofibers grow

Carbon nanotubes only a few atoms in diameter could become the basis of important new technologies ranging from molecular-scale transistors to elevators capable of ascending to space. Yet longstanding uncertainties about how nanotubes and other ultrathin carbon fibers grow are slowing efforts to realize such visions (SN: 10/5/02, p. 218: Ribbon to the Stars). That knowledge gap has also stymied engineers trying to prevent the unwanted formation of nanoscale carbon whiskers in various industrial chemical processes where the fibers inactivate catalysts.
