"thermally conducting Boron nitride nanotubes (BNNTs) stronger and more resistant to high temperatures than carbon nanotubes... conduct heat, insulate electrical current and block radiation... stable at up to 1800°C in inert environment in which manufactured.... can withstand temperatures at 2200°C for short periods... Anything that gets hot, like a turbine or engine, might use them to function in high-temperature environment... medicine delivery systems, high-performance electronics, space travel"
