Laser-based Process Purifies Carbon Nanotubes

Abstract:
Conventional ways of purifying carbon nanotubes -- necessary if they are to be used in the future as ultrastrong fibers, electrical wires in molecular devices or hydrogen fuel cell components -- are expensive processes that often result in some tubes being damaged or destroyed. Now a simpler method has been discovered that safely cleans the tubes by zapping them with carefully calibrated laser pulses.
