This book presents and discusses research in the study of chemical and biochemical kinetics -- the science which deals with the changes over time. Topics discussed include the mechanism of catalysis with nickel (II) complexes in toluene and cumene oxidations by dioxygen; the effect of two oxazoles on membrane lipid structure of liver microsomes calculations of bond energy and the structure and properties of polymer adsorption layers on inorganic pigments surface in aqueous dispersion formed under ultrasonic treatment.
