Advancing Energy Technologies with Ultralong Carbon Nanotubes

Carbon nanotubes are a unique family of molecules that look like tiny carbon tunnels with honeycomb walls. They are typically around 1 nanometre in diameter and several nanometres long. In principle, carbon nanotubes are much more efficient at conducting electricity than metals, especially since they are so lightweight and have high-temperature stability compared to metals. So far, however, their full potential has been limited by the techniques used to manufacture them.
