NSF Expert Panel
“The effect of nanotechnology on the health, wealth and standard of living for people in this century could be at least as significant as the combined influences of microelectronics, medical imaging, computer aided engineering and man-made polymers developed in the past century”.

Combining Carbon Nanotubes with Nanocrystalline Cellulose? Carbon nanotubes (CNTs)
are used in baseball bats, tennis racquets, and some car parts because of their greater mechanical strength at less weight per unit volume than that of conventional materials. Electronic properties of CNTs have made them a candidate for flat panel displays in TVs, batteries, and other electronics. Nanotubes for various uses can be made of materials other than carbon.
