Solution Dynamics and Equilibria
Our research is concerned with the kinetics and mechanisms of the reactions of metal ions in solution. We use a range of experimental techniques, many of which we have developed or adapted to study these processes under special conditions.
High pressure is an extremely useful technique to probe the details of kinetic and equilibrium behavior. The kilobar pressures we use are typical of hydrothermal conditions or deep ocean waters. High pressure measurements allow us to determine the molecular and solvent related volume changes that occur during reaction and give us insight into the intimate reaction mechanism.
Systems studied recently include reactions of macrocyclic and polycarboxylate complexes, using high pressure NMR and pectrophotometric techniques, and redox reactions of metal complexes studied using high pressure electrochemical techniques. [1, 2, 5]
The chemistry of dissolution and precipitation of minerals under hydrothermal conditions are important aspects of the refining of bauxite to alumina. We have collaborative research programs to probe the kinetic characteristics of these reactions at high temperature and pressure.
The use of online and new technologies is now an integral aspect of the way we support the teaching and learning of chemistry. The development of these resources has been a parallel line of interest and we are involved in a range of projects in this area. [3,4]
