The thermal conductance of nanotubes is examined over a wide temperature range and as a function of mechanical manipulation. It is found that carbon nanotubes maintain impressive thermal conductance up to their decomposition temperature of ∼3200 K. For both carbon and boron nitride multiwalled nanotubes the thermal conductance is relatively independent of tube bending angle, but it can be substantially tuned by “telescoping” the tubes.
