In this study, we theoretically investigated Methyl hydrazinecarbodithioate by quantum chemical calculations for geometry optimization, vibration frequencies, and electronic structure parameters. The geometry optimization by DFT, ab initio MP2 method and the frequency calculation by DFT method was performed at the highest available Pople style 6-311G++(3df,3pd) basis set level. The semi-emp...

In this paper, the director distribution is calculated for a nematic liquid crystal, in the cell with different surface anchoring conditions and external fields. The effects of finite and infinite surface anchoring on molecular orientations for one dimensional geometry are discussed. In these situations, the planar alignment is considered. Then, in a two dimensional geometry the planar and homo...

Mixed-ligand Cu(II) complex was prepared by reaction of salicylaldehyde S-benzylisothiosemicarbazone hydrogenchloride ligand (H2L), Cu(ACo)2.H2O and 1,10-phenanthroline with general formulas [Cu(Phen)2Cl].H2L,Cl,H2O. Its structure was fully characterized by elemental analysis and IR method and single crystal diffraction was also used to better understanding of the molecular structure of the Cu(...

Interactions of 3,3',4,4'-tetrahydroxybiphenyl (BPT) and three isomeric 3,3",4,4"-tetrahydroxyterphenyls (OTT, MTT, PTT) with Alzheimer’s amyloid-β peptide (Aβ) were studied by molecular dynamics simulation and molecular docking. Structural parameters such as Root-mean-square derivations (RMSD), radial distribution function (RDF), helix percentage and other physical parameters were obtained. Th...
