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...
we have performed a density functional theory investigation on the structural and electronic properties of pristine and nitrogen-doped tio2 anatase nanoparticles as the adsorbents for removal and degradation of hydrazine molecules in the environment. we have presented the most stable adsorption configurations and examined the interaction of hydrazine molecule with these doped and undoped nanopa...
Adsorption of NO2 molecule on pristine and N-doped TiO2 anatase nanoparticles have been studied using the density functional theory (DFT) technique. The structural properties (such as bond lengths and bond angles) and the electronic properties (such as density of states, band structures and atomic partial charges) have been computed for considered nanoparticles. The result...
electrical sensitivity of a boron nitride nanotube (bnnt) was examined toward aniline (c6h5nh2) molecule by using density functional theory (dft) calculations at the b3lyp/6-31g (d) level, and it was found that the adsorption energy (ead) of aniline on the pristine nanotubes is a bout -19.03kcal/mol. but when nanotube has been doped with si and al atomes, the adsorption energy of aniline molecu...

electrical sensitivity of a boron nitride nanotube (bnnt) was examined toward hydroquinone (c6h4(oh)2) molecule by using density functional theory (dft) calculations at the b3lyp/6-31g(d) level, and it was found that the adsorption energy (ead) of hydroquinone on the pristine nanotube is a bout -7.77kcal/mol. but when nanotubes have been doped with si and al atomes, the adsorption energy of hy...
abstract: electrical sensitivity of a boron nitride nanotube (bnnt) was examined toward ethyl acetylene (c4h6) molecule by using density functional theory (dft) calculations at the b3lyp/6-31g (d) level, and it was found that the adsorption energy (ead) of ethyl acetylene the pristine nanotubes is about -1.60kcal/mol. but when nanotube has been doped with si and al atoms, the adsorption energy ...
The interactions between N-hydroxyurea (NHU) as anticancer drug and SWCNTs (pure and Fe-doped) were investigated with density functional theory. In this study, large long-range corrected CAM-B3LYP and B3LYP were employed to investigate the stability of the different NHU-CNT and NHU/Fe-CNT complexes in the gas phase and solution (water). The presence of an iron atom would create suitable space o...
