ChE SEMINAR:ELECTROCHEMICAL ENGINEERING IN SERVICE TO SOCIETY

Details

Abstract: Electrochemical engineering represents the extension of chemical engineering to species and processes influenced by electrical potential. Just as chemical engineering researchers have migrated from optimizing chemical plants to studying applied chemical engineering science, electrochemical engineering researchers have moved from supporting electrochemical production of commodity chemicals to applying electrochemical engineering science to devices and concepts of modern interest.

The objective of this presentation is to explore some of the areas in which our group has applied electrochemical engineering principles to systems of interest to society. The topics include development of electrokinetic methods to reduce the environmental impact of phosphate mining in Florida, the development of mathematical models for the cathodic protection of pipelines and pipeline networks, and models to interpret impedance spectroscopy data to extract properties of oxides on metals.

Bio: Mark Orazem is a Distinguished Professor of Chemical Engineering at the University of Florida. Prof. Orazem is a Fellow of both the Electrochemical Society and the International Society of Electrochemistry, and he served as President of the International Society of Electrochemistry in 2011-2013. He is a specialist of electrochemical engineering, and his work has encompassed models for cathodic protection of pipeline networks, mechanistic models for corrosion, characterization of electrodes used to stimulate neurons, characterization of enzymatic glucose sensors, electrokinetic separation of clay from effluent produced by the phosphate mining industry, and electrochemical impedance spectroscopy. He co-authored, with Bernard Tribollet, a textbook entitled Electrochemical Impedance Spectroscopy, now in its second edition. Both editions were translated into Chinese and published by Chemical Industry Press. His edited book on Underground Pipeline Corrosion was published by Woodhead Publishing in 2014. In 2012, Prof. Orazem received the Henry B. Linford Award of the Electrochemical Society. With his co-author Bernard Tribollet, Prof. Orazem is a recipient of the inaugural 2019 Claude Gabrielli Award for contributions to electrochemical impedance spectroscopy. Prof. Orazem also received the 2022 Electrochemical Society Corrosion Division H. H. Uhlig Award.
