Breathing Nanotubes Pop Out Buckyballs Like Peas in a Pod, Seoul National University Study

Researchers have previously created molecules capable of automatically forming into tiny tubes, but these are just inert pipes. Now Myongsoo Lee of the Seoul National University in South Korea and colleagues have designed nanotubes that can expand and contract.
