Scientists scale terahertz peaks in nanotubes

Carbon nanotubes carry plasmonic signals in the terahertz range of the electromagnetic spectrum, but only if they’re metallic by nature or doped. In new research, the Rice University laboratory of physicist Junichiro Kono disproved previous theories that dominant terahertz response comes from narrow-gap semiconducting nanotubes.

Nanotube scale can weigh a proton

Even the most obsessive dieter might find this a bit much - a set of scales so accurate that it can weigh a single proton.
