The aim of the present study is to synthesize the oxovanadium complex of the V3+ ion with isatin sciff bases. Spectroscopic methods have been used to confirm these models of complexation and to understand the structures of the species formed in methanolic solution. We also have isolated a complex of Vanadium (III) with isatin schiff bases in the solid phase.

We study the solvation and the association properties of ion pairs in aqueous dimethyl sulfoxide (DMSO) solution by atomistic molecular dynamics (MD) simulations. The ion pair is composed of two lithium and a single sulfonated diphenyl sulfone ion whose properties are studied under the influence of different DMSO concentrations. For increasing mole fractions of DMSO, we observe a non-ideal beha...

The solubility of CdF2 in the mixed solvent (water(1)+ethanol(2)) with mass fraction, W1 = 0.9,was determined by using solvent evaporating method in the presence of various concentrations(0.100, 0.200, 0.300, 0.400, 0.500, 0.600, 0.800 and 1.500 mo1.1)) of NaCI at 25°C. The values ofsolubility and solubility product constant of CdF2 in the mixed solvent were evaluated at zero ionicstrength upon...

the ip3r calcium release channel has been simulated using a stochastic simulation algorithm (ssa;gillespie algorithm) and de young-keiser model. a set of different concentration for cat' and ip3 havebeen used. considering the number of molecules in each state, a non linear behavior of the system can beseen clearly. the inhibiting role of the ca+2 on the open state (x110) has been studied. the d...

in this paper, we used quantum chemical approach to shed light on the catalytic mechanism of γ-carbonic anhydrase (γ-ca) to convert carbon dioxide to bicarbonate ion. density functional theory (dft) using b3lyp and ub3lyp functional and three split-valance including 6-31g*, 6-311g** and 6-311++g** basis sets were used to calculate the details of electronic structure and electronic energy of act...

Siilver tetrafluoroborate complex of 5.11.17.23-tetra-tert-butyl-25-26,27,28-tetrakis (diphenylphosphinoylmethoxy)calyx[4]arene (L) has been synthesized by reaction of silver tetrafluoroborate and L in dichloromethane at room temperature. The complex formed has a 1:1 metall/ligand ratio. 1H and 31P NMR data support an encapsulated structure of the complex in which silv...
