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.

Boron Nitride Nanotubes and Nanosheets

ACS Nano, 2010
Hexagonal boron nitride (h-BN) is a layered material with a graphite-like structure in which planar networks of BN hexagons are regularly stacked. As the structural analogue of a carbon nanotube (CNT), a BN nanotube (BNNT) was first predicted in 1994; since then, it has become one of the most intriguing non-carbon nanotubes.

“White Graphenes”: Boron Nitride Nanoribbons via Boron Nitride Nanotube Unwrapping

Nano Letters, 2010
Inspired by rich physics and functionalities of graphenes, scientists have taken an intensive interest in two-dimensional (2D) crystals of h-BN (analogue of graphite, so-called "white" graphite). Recent calculations have predicted the exciting potentials of BN nanoribbons in spintronics due to tunable magnetic and electrical properties; however no ...

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.

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 ∼
