Buckytubes may be high-temp superconductors

from the intriguing-possibilities dept.
According to a press release, researchers at the University of Houston in Texas have found subtle signs of superconductivity in multi-walled carbon nanotubes (MNTs). The researchers did not see zero resistance in their bundles. They think this is because the connections between the tiny tubes never become superconducting. But they did see more subtle signs of superconductivity within the tubes themselves. The work is preliminary, and other possible explanations need to be eliminated.
