Gamble, Donald S. - St. Mary's University

个人简介

Donald Gamble is a native of Amherst Nova Scotia, and began studying high school chemistry there. He is married and has a son and two daughters. He has studied and worked in four Canadian Provinces and one American State, but is now back in Nova Scotia. He has worked in all three sectors of industry, government and university, publishing an integrated mix of theory and experiment. His publications have produced a number of original solutions to environmental chemistry problems at the basic science level. Supervision has also been provided for a number of graduate students who have gone on to successful careers. He continues a lifetime membership in the Chemical Institute of Canada, having held offices at the local section level and national level, including chairmanship of the Environment Division. He continues to identify environmental problems in need of basic and applied chemical research.

研究领域

Research interests focus on predictive chemical calculations for hydrophobic molecules and metal ions in complicated irregular mixtures. The reason is that this is the area of pure science that is required for making possible, some solutions to practical environmental problems. Solutions to some industrial or biological problems might also be opened up. Some particular research issues in irregular mixtures are of interest because they are necessary support for the focus. These include chemical stoichiometry, sorption and reactions at solution - solid interfaces, intraparticle diffusion, and the resulting kinetics of approach to equilibrium and irreversible final states. Practical examples include pesticides, hydrocarbons, and heavy metals in soils and sediments.
