Symmetry Breaking in Boron Nitride Nanotubes

Physical Review Letters, 2006
We have imaged boron nitride nanotubes with atomic scale resolution using scanning tunneling microscopy. While some nanotubes show the expected triangular lattice pattern, the majority of the nanotubes show unusual stripe patterns which break the underlying symmetry of the boron nitride lattice.

Continuum modeling of boron nitride nanotubes

Nanotechnology, 2008
Boron nitride nanotubes display unique properties and have many potential applications. A finite-deformation shell theory is developed for boron nitride nanotubes directly from the interatomic potential to account for the effect of bending and curvature.

Apatite formability of boron nitride nanotubes

Nanotechnology, 2011
This study investigates the ability of boron nitride nanotubes (BNNTs) to induce apatite formation in a simulated body fluid environment for a period of 7, 14 and 28 days. BNNTs, when soaked in the simulated body fluid, are found to induce hydroxyapatite (HA) precipitation on their surface. The precipitation process has an initial incubation period of ∼

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.
