Abstract
A method for annealing multi-walled carbon nanotubes includes applying a high-frequency electromagnetic field to the carbon nanotubes and causing the carbon nanotubes to self-heat to a temperature and for a time effective to reduce defects and reduce a number of walls in some of the carbon nanotubes.
