There is a compelling reason to design cost-effective sensors detect and measure harmful molecules such as dichlorosilane (H 2 SiCl ) in the air. In this work, density functional theory (DFT) has been used study nature of intermolecular interactions between H gas molecule with single-walled pristine, Al-doped, Ga-doped boron nitride nanotubes (BNNT, BNAlNT, BNGaNT, respectively) investigate the...

The high water flow rates observed in carbon nanotubes (CNTs) have previously been attributed to the unfavorable energetic interaction between the liquid and the graphitic walls of the CNTs. This paper reports molecular dynamics simulations of water flow in carbon, boron nitride, and silicon carbide nanotubes that show the effect of the solid-liquid interactions on the fluid flow. Alongside an ...

A variable pressure (up to 10 atm) powder/gas/liquid injection inductively coupled plasma system has been developed and used to produce high-quality boron nitride nanotubes (BNNTs) at continuous production rates of 35 g/h. Under suitable conditions, collapsed BN nanotubes (i.e., nanoribbons), and closed shell BN capsules (i.e., nanococoons) are also obtained. The process is adaptable to a large...

We provide insight into the interaction of boron nitride nanotubes (BNNTs) with cell membranes to better understand their improved biocompatibility compared to carbon nanotubes (CNTs). Contrary to CNTs, no computational studies exist investigating the insertion mechanism and stability of BNNTs in membranes. Our molecular dynamics simulations demonstrate that BNNTs are spontaneously attracted to...

Single-wall boron nitride nanotubes samples synthesized by laser vaporization of a hexagonal BN target under a nitrogen atmosphere are studied by UV and visible Raman spectroscopy. We show that resonant conditions are necessary for investigating phonon modes of BNNTs. Raman excitation in the UV (229 nm) provides preresonant conditions, allowing the identification of the A1 tangential mode at 13...

Double-walled TiO2 nanotubes with porous wall morphologies are fabricated by anodization under ultraviolet (UV) irradiation. TiO2 formed by anodization of Ti is activated to generate electrons and holes by UV and the anodization process is influenced by the photo-generated charges. As a consequence, morphologies of the fabricated TiO2 nanotubes can be adjusted by controlling the UV illumination...

Selective growth of boron nitride nanotubes (BNNTs) was demonstrated by plasma-enhanced pulsed laser deposition (PE-PLD). Although PLD is a physical vapor deposition technique for the growth of boron nitride (BN) thin films, ion sputtering induced by the plasma can eliminate the formation of BN thin films and lead to the so-called total resputtering region, in which, a pure phase of BNNTs can b...

Direct measurement of local phonon dispersion in individual nanostructures can greatly advance our understanding their electrical, thermal, and mechanical properties. However, such experimental measurements require extremely high detection sensitivity combined spatial, energy momentum resolutions, thus has been elusive. Here, we develop a four-dimensional electron loss spectroscopy (4D-EELS) te...
