Purification of Boron Nitride Multiwalled Nanotubes
Journal of Nanoscience and Nanotechnology, 2007Purification of arc-discharge grown multiwalled boron nitride nanotubes (BN MWNTs) was possible using a simple solubilization and filtration method. Using the common method of arc-discharge with h-BN/Ni/B packed molybdenum tube and a water cooled copper cathode, results in a mixture of hexagonal boron nitride, metal catalyst and boron nitride nanotubes.

Purification of Single-Walled Boron Nitride Nanotubes and Boron Nitride Cages
Journal of Nanoscience and Nanotechnology, 2007Continuous laser vaporization of a BN target under N2 atmosphere is up to now the unique route to single-walled boron nitride nanotubes (BN-SWNTs). Although grams of product can be obtained by this technique, the raw material contains in addition to the BN-SWNTs, different by-products made of boron and nitrogen.

Boron Nitride Nanotube Composites and Applications
2019Boron nitride nanotubes (BNNTs), like carbon nanotubes (CNTs), possess an impressive collection of properties that motivate their use in composite materials, particularly in areas where CNTs are limited (e.g., high-temperature processing and applications) or unsuitable (e.g., electric insulation).

Mechanosynthesis of Boron Nitride Nanotubes
Chinese Journal of Chemical Engineering, 2006Abstract Boron nitride nanotubes (BN-NTs) with pure hexagonal BN phase have been synthesized by heating ball-milled boron powders in flowing ammonia gas at a temperature of 1200°C. The as-synthesized products were characterized by X-ray powder diffraction, transmission electron microscopy, high-resolution transmission electron microscopy, and ...

Engineering Boron Vacancy Defects in Boron Nitride Nanotubes
ACS Applied Materials & InterfacesSpin defects in hexagonal boron nitride (hBN) are emerging as promising platforms for quantum sensing applications. In particular, the negatively charged boron vacancy (VB-) centers have been engineered in bulk hBN and few-layer hBN flakes, and employed for sensing.

Properties of Boron Nitride Nanotubes
AIP Conference Proceedings, 2003We examine properties of boron nitride nanotubes and contrast them to those of carbon nanotubes. Boron nitride nanotubes are expected to be as desirable for application as carbon nanotubes. Although boron nitride nanotubes are wide band gap semiconductors and electrically nearly insulating, scanning tunneling microscopy can be used to image and ...
