Purification of Boron Nitride Multiwalled Nanotubes

Journal of Nanoscience and Nanotechnology, 2007
Purification 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.

Junctions between a boron nitride nanotube and a boron nitride sheet

Nanotechnology, 2008
For future nanoelectromechanical signalling devices, it is vital to understand how to connect various nanostructures. Since boron nitride nanostructures are believed to be good electronic materials, in this paper we elucidate the classification of defect geometries for combining boron nitride structures.

Boron Nitride Nanotube Peapods

AIP Conference Proceedings, 2002
We demonstrate that boron nitride (BN) nanotubes can be filled “peapod” fashion with C60 molecules. Filling small‐diameter BN nanotubes results in a linear chain of C60 molecules in the interior, while filling large diameter BN nanotubes leads to nanorods of crystalline C60 in the interior.

Purification of Single-Walled Boron Nitride Nanotubes and Boron Nitride Cages

Journal of Nanoscience and Nanotechnology, 2007
Continuous 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

2019
Boron 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).

Boron nitride nanotubes/polystyrene composites

Journal of Materials Research, 2006
Boron nitride nanotube (BNNT)/polystyrene (PS) composite films were fabricated for the first time using high-quality BNNTs synthesized via a chemical-vapor-deposition method. The composite films exhibited good transparency. Tensile tests indicated that the elastic modulus of the films was increased by ∼21% when a ∼1 wt% soluble BNNT fraction was in use.

Structure of boron nitride nanotubes

Crystallography Reports, 2015
The crystallographic structure of boron nitride nanotubes has been investigated. Various defects that may arise during nanotube synthesis are revealed by electron microscopy. Nanotubes with different numbers of walls and different diameters are modeled by molecular dynamics methods. Structural features of single-wall nanotubes are demonstrated.

Amine-functionalized boron nitride nanotubes

Solid State Communications, 2007
The surface of boron nitride nanotubes (BNNTs) has been functionalized with amine groups via ammonia plasma irradiation. The functionalized tubes were characterized by Fourier transform infrared spectroscopy and electron energy loss spectroscopy. Amine-functionalized BNNTs were found to be highly dispersible in chloroform, and are predicted to form the

Boron nitride nanotube branched nanojunctions

Nanotechnology, 2007
One-dimensional boron nitride (BN) nanotube nanojunctions are of great interest for both fundamental and applied research because of their stable and excellent mechanical and physical properties. Large quantities of highly pure BN nanotube multiple Y- and/or T-junctions were synthesized by annealing pure boron nanowire precursors in N-2 atmosphere at ...

Mechanosynthesis of Boron Nitride Nanotubes

Chinese Journal of Chemical Engineering, 2006
Abstract 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 ...
