Density functional theory (DFT) calculations were carried out on the studied molecules in water using the Amsterdam Density Functional (ADF) program [63] developed by Baerends and co-workers [64,65,66,67,68]. All molecular structures were optimized at the hybrid-type B3LYP functional (Becke’s...
Molecular mechanics Poisson–Boltzmann surface area calculation Molecular Mechanics Poisson–Boltzmann Surface Area (MM-PBSA) is a computational approach utilized to predict the binding free energy of protein-ligand complexes. In this study, we employed g_mmpbsa—a GROMACS Tool for High-Throughput MM-...

Fig. 9.7. Calculation of wear volume (ΔV). V=π6(h2)2(3d−2h2) The wear volume was plotted versus the sliding distance, L, which was derived from the rotational frequency, f, the ball diameter, d, and the test duration, t, according to L=(π2) After a running-in phase, ...
Therefore, NBO calculation was used at the B3LYP/6-31G(d,p) level to determine stabilization energy (E(2))72,73, and to specify partial charge on the selected atoms, as well. Then the highest values of E(2), namely the strongest interactions, were selected to examine interactions in ...
The relative energies show that in all tautomers and complexes, ketone and thione forms are more stable than enol and thienol forms, and also Z isomers are more stable than E isomers. Moreover, the NBO calculation is carried out for tautomers and complexes to obtain atomic charges and ...
