Scientists Build the Smallest Cable Containing a Spin Switch

A research work published in Nature Communications, involving researchers from the Madrid Institute for Advanced Studies in Nanoscience (IMDEA) and the University of Sevilla, has measured for the first time the electrical conductivity of a single carbon nanotube with spin-crosslinked molecules inside it.

Researchers Create Artificial Muscles by Twisting and Coiling Carbon Nanotubes

For more than 15 years, researchers at The University of Texas at Dallas and their collaborators in the U.S., Australia, South Korea and China have fabricated artificial muscles by twisting and coiling carbon nanotube or polymer yarns. When thermally powered, these muscles actuate by contracting their length when heated and returning to their initial length when cooled. Such thermally driven artificial muscles, however, have limitations.
