Abstract:
Researchers have already made pure boron nanowires, and theoretical studies indicate that hollow boron nanotubes should be stable; they might even be better conductors of electricity than carbon nanotubes. Dragos Ciuparu et al. now claim to have made the first pure boron nanotubes, by reacting boron trichloride with hydrogen gas at 870°C. The tubes are single-walled and measure about 3 nanometres in diameter.
