For example, a new form of carbon, the nanotube, was discovered by S S S S S uuuu mmmm iiii oooo I I I I iiii jjjj iiii mmmm aaaa in In 1995, it was recognized that carbon nanotubes were excellent sources of field-emitted electrons. By 2000, the jumbotron lamp, was comercially used in atheletic stadiums. Buckyballs. The discovery of another nanoscale carbon form, C60, the fullerene (also called the buckyball) brought the N N N N N oooo bbbb eeee llll P P P P rrrr iiii zzzz eeee i i i i nnnn C C C C hhhh eeee mmmm iiii ssss tttt rrrr yyyy in 1996 to Robert F. Curl Jr., Sir Harold W. Kroto, and Richard E. Smalley. It also started an avalanche of research into not only the novel characteristics of C60, but also other nanoscale materials.
