Isothermal titration calorimetry (ITC) is a popular chemical analysis technique that can be used to measure macromolecular interactions and physical processes. ITC involves the measurement of heat flow from cell after each injection during experiment. has been useful thermodynamics such as protein-ligand or protein-protein binding affinity also processes enzyme catalyzed reactions. The use in b...

Interaction of Schiff base complexes of Iron and Manganese: Iron [N, N’ Bis (5(triphenyl phosphonium methyl) salicylidene) -1, 2 ethanediamine) chloride, [Fe Salen]Cl; Manganese [N, N’ Bis (5(triphenyl phosphonium methyl) salicylidene) -1, 2 ethanediamine) acetate, were investigated by spectroscopic and isothermal titration calorimetry techniques (ITC). The absorbance spectra of complexes have ...

In this study, the high-resolution ultrasonic spectroscopy (HR-US) technique was applied to examine interpolyelectrolyte neutralization. The mentioned method tested on example of complexation between poly(allylammonium) cations and poly(acrylate) anions in aqueous solutions at pH = 7. It confirmed by HR-US that type titration (stepwise or abrupt), direction titration, background salt affect out...
