Abstract: The electrochemical properties of -diketonate complexes, such as [Co(tta)2(H2O)2], [Ni(tta)2(H2O)2], [Cu(tta)2] and [Zn(tta)2(H2O)2] (tta = deprotonated of 1-thenoyl-4,4,4-trifluoroacetone) have been studied using cyclic voltammetry (CV). Their redox behaviors including oxidation and/ or reduction process for both central atom and tta ligand have... Show More

Abstract: The values of free energies, the heats of combustion and formation in condensed and gaseous phases over 30 amino acids of different structure were analyzed. Entropies and heat capacities in standard conditions were considered too. Twenty one equations of such type as Yо = i ± f (N – g) +Σ(hc)j, in which Yо is thermodynamic function or heat capaci...

Abstract: Four sulfated fatty acid diethanolamine complexes (DC) were synthesized based on four different types of vegetables oils and tested as corrosion inhibitors of mild steel in CO2-saturated 1% NaCl solution at 50 °C. Results ob-tained show that the surfactants studied are efficient corrosion inhibitors for mild steel even at low concentrations. It is ... Show More
