Isotope Effect on the Thermal Conductivity of Boron Nitride Nanotubes [link]Paper  abstract   bibtex   
We have measured the temperature-dependent thermal conductivity κ(T) of individual multiwall boron nitride nanotubes using a microfabricated test fixture that allows direct transmission electron microscopy characterization of the tube being measured. κ(T) is exceptionally sensitive to isotopic substitution, with a 50% enhancement in κ(T) resulting for boron nitride nanotubes with 99.5% B11. For isotopically pure boron nitride nanotubes, κ rivals that of carbon nanotubes of similar diameter.
