hno detection by nanosized b12n12 cage: a dft/tddft study
Authors
abstract
the interaction of a nitrosyl hydride (hno) molecule with b12n12 nanocage was explored by means of density functional calculations. it was found that hno prefers to be adsorbing on a boron atom of the cage with adsorption energy of -0.65 ev. this adsorption process significantly shifts the homo-lumo gap (eg) of the cage to lower energies, thereby reducing eg of the cage from 6.84 to 2.45 ev. time-dependent density functional theory (tddft) calculations show a high intensity peak in 381.38 nm in the most stable complexes of hno with b12n12. the change in electronic properties of the b12n12 nanocage on hno adsorption is significant enough to consider it a potential sensor for hno detection.

HNO Detection by Nanosized B12N12 Cage: A DFT/TDDFT Study
The interaction of a nitrosyl hydride (HNO) molecule with B12N12 nanocage was explored by means of density functional calculations. It was found that HNO prefers to be adsorbing on a boron atom of the cage with adsorption energy of -0.65 eV. This adsorption process significantly shifts the HOMO-LUMO gap (Eg) of the cage to lower energies, thereby reducing Eg of the cage from 6.84 to 2.45 eV. Ti...

Abstract: The opteoelectronical properties of B12N12 nano-cage was investigated in thepresent of some metals by density functional theory (DFT). After the adsorption of atoxic molecule with all complexes, the electronic properties in B11GeN12 nano-cagewere significantly increased. The UV-Vis adsorption and Infrared spectroscopy ofcyanogen chloride over the B11GeN12 have ...

In this study, the performance of fullerene (C20) and boron nitride cage (B12N12) as a sensing material for detection of proline was evaluated by density functional theory. For this purpose, the structures of proline, C20, B12N12 and the derived products from the proline adsorption on the surface of nanostructures were optimized geometrically. Then, IR and Frontier molecular orbital calculation...
full textDetection of nitroxyl (HNO) by membrane inlet mass spectrometry.
Membrane inlet (or introduction) mass spectrometry (MIMS) was used to detect nitroxyl (HNO) in aqueous solution for the first time. The common HNO donors Angeli's salt (AS) and Piloty's acid (PA), along with a newly developed donor, 2-bromo-N-hydroxybenzenesulfonamide (2-bromo-Piloty's acid, 2BrPA), were examined by this technique. MIMS experiments revealed that under physiological conditions 2...
full texta study on insurer solvency by panel data model: the case of iranian insurance market
the aim of this thesis is an approach for assessing insurer’s solvency for iranian insurance companies. we use of economic data with both time series and cross-sectional variation, thus by using the panel data model will survey the insurer solvency.
Comparative biomechanical study of cervical spine stabilisation by cage alone, cage with plate, or plate-cage: a porcine model.
PURPOSE To compare stability and subsidence associated with 3 types of cervical spine stabilisation. METHODS The C3 to C4 vertebrae of 28 Polish pigs were used. Pigs with intact vertebrae (group 1) underwent standard anterior cervical discectomy (group 2), followed by stabilisation using a cage alone (group 3), a cage with plate (group 4), or a plate-cage (group 5). Cervical spine stability a...
