the effect of vanillin on the corrosion behavior of aa6061 al alloy in 3.5% nacl solution wasinvestigated using potentiodynamic polarization and electrochemical noise (en) techniques. vanillinoffers interesting possibilities for corrosion inhibition due to its nontoxicity and high solubility inaqueous media. the best inhibition effect at 200 ppm vanillin was a marked characteristic of theinhibi...

having conducted fundamental projects, scientists have expressed their hope to develop the use of carbon nanotubes to release drugs. it is important to release drugs in cell without damaging healthy cells of tissues under study. researchers have shown the fact that nanotubes can perform this function perfectly. to this objective, in the present study the interactions between four anti-cancer dr...

The Density of State and the Natural Bond Orbital calculations were carried out to study theoxidation of CO on Au14 nano cluster through two different mechanisms and determining the bestmechanism for the reaction. Chemisorption of O2 and CO on the nano cluster led to change in energy,density of state and its thermodynamic properties. We calculated the energy band gap between thehighest occupied...

In this article, the optimized geometry, IR and UV spectra, frontier orbital analysis, natural bond orbital (NBO) analyses, and thermodynamic parameters of pomalidomide were investigated. The calculated structural parameters and stretching frequencies values are compared with experimentalvalues of the investigated compound. Also, the relations of the thermodynamic functions vs.temperatures were...

In the present work, the structural and electronic properties, and conductivity of (5,5) and (6,6) Single Walled Carbon Nanotubes in the ground state have done by using the Hartree-Fock and density functional theory DFT-B3LYP/6-31G* level.

A new condensed form of the Fukui function, the natural orbital Fukui function (NOFF), is proposed and derived from natural bond orbital occupancy. It is defined as the change in natural bond orbital occupancy upon electronic perturbation (electron addition to, or depletion from, a molecular system). Applying NOFF to a series of cycloaddition reactions (e.g., [4 + 2] and [2 + 1] cycloadditions)...
