Nanotubes harden up under pressure

Researchers at Los Alamos National Laboratory, the University of Arizona and Cornell University, all in the US, have made a superhard phase of carbon by applying pressure to carbon nanotubes. The material was at least as hard as cubic diamond and retained its properties at room temperature even when the pressure was removed.
