Description:  The top image shows a diagram of a multiwall nanotube with its outer layers selectively broken via jolts of electricity. The bottom image depicts a clump, or rope, of nanotubes stuck together. Researchers can destroy the metallic nanotubes with electricity, leaving a rope containing only semi-conducting nanotubes. The background of each diagram is a microscope image of the actual nanotubes and electrodes.
