dft calculations were used to investigate adsorptionof  f-, cl-, li+ and na+ ions on the exterior surface of mg12o12 nanocage in the gas phase and water media. the most favorite position for adsorption of the studied anions and cations are atop of mg and o atoms of mg12o12, respectively. the strongest interaction is obtained when fluoride is located atop of mg atom with the adsorption energy of...

the absorption of the h2s on the small boron nitride fullerene (b12n12) and its al-inserted analog was theoretically analyzed by density functional theory. the structural stability was based on the minimum energy and non-complex vibrational frequencies. different sites and orientations of h2s, using the monomer unit, were considered. compared with the weak physisorption on the pristine b12n12, ...

ABSTRACT The main objective of this work is to investigate the adsorption of Pyrrole 2-carboxylic acid (PCA) from O, N and C sites on the surface of pristine and Ni doped B12N12 nano cage by using density functional theory (DFT). The results of adsorption energy indicate that the adsorption of PCA on the surface of B12N12 and NiB11N12 is exoth...

In this study, B12N12 Nano ring has been selected because it consist of four 6-side rings and polar bonds B-N which in comparison with non-polar bonds C-C, is more suitable for the study of the absorption of other compounds. So reactivity and stability of Benzene alone and in the presence B12N12 nano ring field checked. To determine the non-bonded interaction energies between Benzene and B12N12...

The electronic sensitivity and adsorption behavior toward cyanogen halides (X-CN; X = F, Cl, and Br) of a B12N12 nanocluster were investigated by means of density functional theory calculations. The X-head of these molecules was predicted to interact weakly with the BN cluster because of the positive σ-hole on the electronic potential surface of halogens. The X-CN molecules interact somewhat st...

Effective vaccines are urgently needed to combat gonorrhea, a common sexually transmitted bacterial infection, for which treatment options are diminishing due to rapid emergence of antibiotic resistance. We have used a rational approach to the development of gonorrhea vaccines, and genetically engineered nanoparticles to present antigenic peptides of Neisseria gonorrhoeae, the causative agent o...

To determine the non-bonded interaction energies between Naphthalene and B12N12 Nano ring in different orientations and distances, geometry of molecules with B3LYP method and 6-31g* basis set optimized. Also reactivity and stability of Naphthalene alone and in the presence B12N12 Nano ring checked. Then calculated the NBO, NMR, FREQ, NICS and muliken charge of Naphthalene atoms alone and in the...

A new structure, consisting of a shell cross-linked, 2 nm size siloxane nanocage containing propylamine groups tethered to the interior face of the shell was synthesized, starting with micelles of the surfactant molecule, (triethoxysilyl)propylcetylcarbamate. After hydrolysis of the ethoxysilyl groups and condensation and capping of the silanols to form a cross-linked, one-atom-layer-thick silo...
