Irradiation-induced vacancy defects in multiwalled (MW) boron nitride nanotubes (BNNTs) are investigated via in situ high-resolution transmission electron microscope operated at 80 kV, with a homogeneous distribution of electron beam intensity. During the irradiation triangle-shaped vacancy defects are gradually generated in MW BNNTs under a mediate electron current density (30 A cm(-2)), by kn...

High electron mobility of graphene has enabled their application in high-frequency analogue devices but their gapless nature has hindered their use in digital switches. In contrast, the structural analogous, h-BN sheets and BN nanotubes (BNNTs) are wide band gap insulators. Here we show that the growth of electrically insulating BNNTs on graphene can enable the use of graphene as effective digi...

The aim of this research is studying the effects of Ge-doped on CO adsorption on the outer and inner surfaces of (6, 0) zigzag model of boron nitride nanotube (BNNTs) by using DFT theory. For this purpose, eight models of CO adsorption on the surfaces of BNNTs are considered. At first step, all structures were optimized at B3LYP and 6-31G (d) standard base set and then the electronic structure,...

Lithium storage and capture are of particular importance for the development new technology in electric vehicles portable electronics. Nanotubes (NTs) among many porous nanomaterials offered as potential candidates lithium storage. In this paper, we adopt a continuum approach together with Lennard–Jones function to determine minimum interaction energies atoms boron nitride nanotubes (BNNTs) car...

This paper reports the influence of surfactant Triton X-100 on boron nitride nanotubes (BNNTs) nanofluid in non-optimized and optimized microchannel heat sink (MCHS) at 30 °C 50 °C. The MCHS performance was evaluated terms thermal resistance pressure drop, utilizing experimental thermophysical properties distilled water, a mixture water as base fluid, BNNTs weight concentration 0.001% into mode...

the monitoring and controlling of environmental pollutions are very important in biological and industrial processes, and a great interest is growing with the development of suitable gas–sensitive materials and hazardous chemical removal devices. in this work, the highly parameterized, empirical exchange–correlation functional m06–2x were employed to investigate the electronic sensitivity of pe...

an efficient method for purification of yard-glass shaped boron nitride nanotubes (yg-bnnts) fabricated via a chemical vapour reaction (cvr) route has been developed. impurities including carbon, boron nitride (bn), and fe species in the pristine yg-bnnt sample are removed by a combined physical and chemical procedure which involves ultrasonication, high temperature oxidation, hot-water washing...
