          | 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. |
