Quantum chemistry calculations have been performed to investigate the kinetic and mechanism of cysteine oxidation using the hydrogen peroxide. For this reaction, four major possible mechanisms have been proposed including ...
NBO Analysis for the Encapsulation of H2O2 in Functionalized B -Cyclodextrin by Density Functional Theory
NBO analysis reveals that the inclusion of H2O2 with beta-CD is stabilized by Van Der Waals
interactions. In addition, NBO analysis gives that mutual interactions between donor and
acceptor orbital of each ...
Quantum Chemistry Description of Some Ionic Liquids: Theoretical Approach
According to the theoretical studies on the ionic liquids, chemical potential of [emim][TCM] is more negative than other ILs and its electrophilicity index is more positive. Considering the results it can be concluded that ...
Glucose Derivatives Substitution and Cyclic peptide Diameter Effects on the Stability of the Self-Assembled Cyclic Peptide Nanotubes; a Joint QM/MD Study
functional theory (DFT) and DFT-D3 methods were performed. Based on the
DFT-D3 calculations, it was revealed that the dispersion interactions play a key
role in the dimerization process. The ring size increment, elevates the dispersion
interaction...
The effects of temperature, alkyl chain length, and anion type on thermophysical properties of the imidazolium based amino acid ionic liquids
and Guggenheim equations. It was shown that the critical temperature decreases with alkyl chain length and
its change depends on the ion pair interaction energy density and density of electronic chemical potential. The results of prediction critical...
The correlation of interaction energy with critical point temperature of ionic liquids obtained from surface tension
Ionic liquids with BF4 anion have small surface entropies and show high critical point temperatures, which decreases with the alkyl chain length. The cation-anion interaction energy, calculated by quantum chemical method, has been correlated...
Critical Point Temperature of Ionic Liquids from Surface Tension at Liquid-Vapor Equilibrium and the Correlation with Interaction Energy
of the ionic liquid, the anion-cation interaction energy (Einter) was calculated by quantum mechanical density functional theory and the correlation with the predicted critical temperature was studied. The predicted critical temperature has a direct correlation...
