Journal ArticleDOI
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
Thermal Properties and Magnetic Susceptibility of Hellmann Potential in Aharonov–Bohm (AB) Flux and Magnetic Fields at Zero and Finite Temperatures
C. O. Edet,P. O. Amadi,Michael C. Onyeaju,Uduakobong S. Okorie,Uduakobong S. Okorie,Ramazan Sever,Gaotsiwe Joel Rampho,Hewa Y. Abdullah,Idris H. Salih,Akpan N. Ikot,Akpan N. Ikot +10 more
TL;DR: In this article, the effect of external magnetic and AB flux fields on the energy spectra of the system is examined in detail, and it is found that the AB field performs better than the magnetic field in its ability to remove degeneracy.
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

Kodakkal Kannan Viswanathan,Jang-Hyun Lee,Zainal Abdul Aziz,Imam Hossain,Wang Rong-qiao,Hewa Y. Abdullah +5 more
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.
