Stiffness and Thickness of Boron-Nitride Nanotubes

Journal of Nanoscience and Nanotechnology, 2008
We establish an analytic approach to determine the tensile and bending stiffness of a hexagonal boron-nitride (h-BN) monolayer and singleand multi-wall boron-nitride nanotubes (BNNTs) directly from the interatomic potential. Such an approach enables one to bypass atomistic simulations and to give the tensile and bending stiffness in terms of the ...

Immobilization of Proteins on Boron Nitride Nanotubes

Journal of the American Chemical Society, 2005
We report for the first time that proteins are immobilized on boron nitride nanotubes. It is found that there is a natural affinity of a protein to BNNT; this means that it can be immobilized on BNNT directly, without usage of an additional coupling reagent. For the most effective immobilization, noncovalently functionalized BNNTs should be used.

Antigenotoxic potential of boron nitride nanotubes

Nanotoxicology, 2018
Boron and boron nitride nanotubes (BNNTs) are increasingly used in different industrial fields and, potentially, in some biomedical areas. As occurs with other nanomaterials (NMs), to increase our knowledge on their potential health hazards is a priority.

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.

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 ∼

Samarium doped boron nitride nanotubes

Applied Radiation and Isotopes, 2018
Boron nitride nanotubes doped in situ with samarium (Sm-doped BNNTs) were synthesized at 1150°C under atmosphere of NH3/N2 gas mixture by thermal chemical vapor deposition (TCVD) using samarium oxide that is a product of the process separation of thorium and uranium tailings.

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.

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).

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.
