Pathways, Kinetics, Mechanisms

The Tratnyek/Johnson Research Group's scope includes a wide range of oxidation-reduction reactions that occur in the environment, and the contribution of these reactions to the fate of pollutants. In most of our work, the focus is on pathways, kinetics, mechanisms, and other fundamental, molecular aspects of environmental chemistry. The goal is to understand these redox processes at a process level, and to use this knowledge to develop deterministic models of environmental systems and remediation technologies.

Cover slide from several recent talks. A version of of this talk is available on you YouTube channel (See Resources / Current Resources). The background is a view of Mount Hood, looking east from the OHSU main campus on Marquam Hill. It is not quite the view from our lab, but close.

Pitting of an iron surface due to carbonate stimulated corrosion in water. It was taken with an environmental scanning electron microscope by Abinash Agrawal (and used here with his permission). We have never published this image, but it is related to work we described in Agrawal et al. 2002. For details, see Publications, Journal Article #XX.
