Breakthrough in industrial-scale nanotube ...(capable of producing high-quality nanotu...)

capable of producing high-quality nanotubes in bulk. HiPco, short for high-pressure carbon monoxide process, broke the logjam on nanotube production and cleared the way for more scientific study and for industry to begin using them in some materials. Industrial nanotube reactors today generate several tons of low-quality carbon nanotubes per year, and the worldwide market for nanotubes is expected to top $2 billion annually within the next decade.

But a final breakthrough remains before the true potential of high-quality carbon nanotubes can be realized. That's because HiPco and all other methods of making high-end, "single-walled" nanotubes generate a hodgepodge of nanotubes with different diameters, lengths and molecular structures. Scientists worldwide are scrambling to find a process that will generate just one kind of nanotube in bulk, like the best-conducting metallic varieties, for instance.

"One good thing about the process that we have right now is that if anybody could give us one gram of pure metallic nanotubes, we could give them one gram of fiber within a few days," Pasquali said.
