The adsorption of chlorofluoromethane on pristine, and Al- and Ga-doped boron nitride nanosheets: a DFT, NBO, and QTAIM study

TL;DR: It was revealed that the sensitivity of the adsorption will be increased when the gas molecule interacts with decorated nanosheets and decrease the HOMO-LUMO band gap; therefore, the change of electronic properties can be used to design suitable nanosensors to detect CFM gas.
Journal ArticleDOI

Vinyl chloride adsorption onto the surface of pristine, Al-, and Ga-doped boron nitride nanotube: A DFT study

TL;DR: In this paper, density functional techniques (DFT) were put into practice to study the nature of the intermolecular interactions between Vinyl chloride (VCM) gas molecule with single-walled pristine, Al and Ga-doped boron nitride nanotubes (BNNT, BNAlNT, and BNGaNT, respectively).
Journal ArticleDOI

2D boron nitride material as a sensor for H2SiCl2

TL;DR: In this paper , the use of boron nitride nanosheets (BNNS) and its aluminum and gallium doped derivatives as sensors for dichlorosilane (C 3 H 7 NO 3 ) gas molecule was studied by employing the B3LYP-D3 model with the 6-311G(d) basis set as well as the PBE0, ωB97XD, and M06-2X functionals.
Journal ArticleDOI

Vibration analysis of cross-ply laminated truncated conical shells using a spline method

TL;DR: In this paper, the free vibration of symmetric and antisymmetric cross-ply composite laminated truncated conical shells using the spline function technique is studied, including first-order shear deformation theory.
