Kinetic studies of the reactions between dichlorido(1,2-diaminoethane)zinc(II) and biologically relevant nucleophiles in the presence of chloride

Posted on 16. April, 2018.

The mole-ratio method was used for determining metal–ligand stoichiometry for the reaction between [ZnCl2(en)] (where en = 1,2-diaminoethane or ethylenediamine) and chloride ion at pH 7.2. The results have shown step-wise formation of 1:1 and 1:2 complexes and indicate additional coordination of chloride ions in the first coordination sphere.

A Kinetic model of proton transport in a multi-redox centre protein: cytochrome c oxidase

Posted on 21. February, 2014.

Cytochrome c Oxidase (CcO) is the final complex of the respiratory chain. Its purpose is to use the energy gained by the reduction of oxygen to water to pump protons against a difference of electrochemical potentials across the mitochondrial inner membrane.

First Principles Kinetics Of n-Octyl Radicals

Posted on 18. February, 2014.

Being the initial product from radical attack on alkanes, alkyl radicals are important intermediates in the decomposition of organic fuels. It has long been known that alkyl radicals reactions play an important role in the combustion and atmospheric degradation pathways of traditional fuels as well as a wide variety of other chemical processes.

Novel approach to the ultrasonic degradation of polymers: development of a general kinetic equation

Posted on 14. January, 2014.

The general applicability of the common kinetic equations is discussed to develop a general kinetic equation for the ultrasonic degradation of polymers. The common ultrasonic-kinetic equations for polymers are used to fit original data collected from the literature. The fitting accuracy is evaluated by the residual standard deviation. The results indicate that the first-order equation and second-order equations are the most accurate and can replace other kinetic equations.

Theoretical study of N2O formation from NO and H2 over Au nanoparticles

Posted on 20. December, 2013.

One of the exciting discoveries in the field of heterogeneous catalysis in the last decade has been the surprisingly high activity of gold-based catalysts towards several reactions of industrial and environmental importance. Gold, formerly considered as an uninteresting material for catalysis because of its unreactive character, was found in the form of nanoparticles, to be an extremely efficient catalyst for a number of important reactions such as CO oxidation, methanol decomposition, and the hydrogenation of unsaturated hydrocarbons.

Transformation of levofloxacin during water chlorination

Posted on 20. December, 2012.

Information on chlorine reaction with pharmaceutical compounds is scarce. An investigation reported in Progress in Reaction Kinetics and Mechanism quantifies the kinetics for reactions of levofloxacin with free available chlorine and also identifies associated transformation, mechanisms, degradation products, and evaluates thermodynamic activation parameters relevant to chlorine based municipal waste water and drinking water disinfection processes.

Free Energies of Electron Transfer Reactions

Posted on 20. September, 2012.

Determination of the reaction and reorganization free energies that control the rate of electron transfer are considered in Progress in Reaction Kinetics and Mechanism. The main difficulty is the lack of knowledge of the properties in the interfacial region where the reaction occurs. This review deals with procedures for obtaining these two free energies from experimental data corresponding to electron transfer reactions under restricted geometry conditions in which one or both reactants are bound to some receptor such as micelles, cyclodextrins, and polymers.

Radiation effects on zeolite nanomaterials - some potential implications for cleaning liquid nuclear waste and for enhanced radioactive decontamination

Posted on 22. May, 2012.

Zeolites are used to help clean liquid wastes from nuclear power plants or to enhance radioactive decontamination. Progress in Reaction Kinetics and Mechanism presents results from the implantation of high energy positive muons in samples of cation-exchanged zeolite X  which give an insight into the long-term effects on zeolites of their exposure to ionising radiation.
