Scientists find way of sorting nanotubes



HOUSTON, June 23 (UPI) -- Scientists at Rice University in Houston have developed a method for sorting semiconducting carbon nanotubes according to their size.

This long-awaited development is reportedly the first of its kind.

Nanotubes are tiny cylinders of carbon about the size as a strand of DNA. They come in many varieties, some with properties that are known to be coveted by material scientists.

Nanotubes are stronger than steel, but weigh only a sixth as much. Some varieties can conduct electricity while others make for good semiconductors.

This most recent discovery of sorting nanotubes could form the basis of a purification system capable of creating next-generation energy, researchers said.

The research on nanotubes is due to appear in the upcoming issue of the Journal of the American Chemical Society.£¨×ª×Ôsciencedaily.com£©
