Boron Nitride Nanotubes

Science, 1995
The successful synthesis of pure boron nitride (BN) nanotubes is reported here. Multi-walled tubes with inner diameters on the order of 1 to 3 nanometers and with lengths up to 200 nanometers were produced in a carbon-free plasma discharge between a BN-packed tungsten rod and a cooled copper electrode.

Boron nitride nanotubes

Carbon, 1998
Abstract Pure boron nitride (BN) nanotubes have been synthesised by arc discharge between HfB2 electrodes in a nitrogen atmosphere. The high resolution electron microscopy (HREM) observations reveal that this route leads to the formation of highly crystalline tubes with reduced numbers of layers, including tubes with only one or two layers.

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.

Solubilization of boron nitride nanotubes

Chemical Communications, 2005
A successful attempt in the functionalization and solubilization of boron nitride nanotubes is reported, and a functionalization mechanism based on interactions of amino functional groups with nanotube surface borons is proposed.

“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.
