Welcome to the Molecular Geochemistry Laboratory

If chemistry is the central science, then geochemistry is the central science as applied to understanding the natural world around us.

Geochemists seek to answer questions relating to the evolution of life on Earth and how metalloenzymes may have evolved, the chemistry of the oceans and how they are affected by global warming, the interplay between flora, fauna and the environment in chemical terms, how pollutants interact with soils and minerals, and how radioactive waste can be securely stored for millennia. We do this by connecting the very big — mountains — with the very small — atoms and molecules, and the very fast — fundamental reactions — with the often very slow — weathering

Abstract: Density functional theory is used to explore the locus and consequences of protonation in [Zn4(H2O)2(PW9O34)2]10− . The results are used to explain recent observations regarding the contrasting pH effects on the water-ligand exchange in [Mn4(H2O)2(P2W15O56)2]16− and [Co4(H2O)2(P2W15O56)2]16− , and the general effect of protonation on solvent exchange in metal oxides is discussed.
