Dr. Bruce C. Gibb from the Department of Chemistry, Tulane University will present "Studying and Utilizing the Supramolecular Interactions behind the Hofmeister and Reverse Hofmeister Effects."
Abstract: A better understanding of how molecules interact in aqueous solutions has ramifications across all the major areas of science. For example, aqueous solutions of dissolved organic molecules and salts are central to biochemistry, and on a larger scale, biology. Water interacts very differently with the charged groups and the non-polar moieties of organic molecules, and between these two extremes are a plethora of non-covalent interactions that control hydration, solubility, and the hydrophobic effect. In Nature however, things are never that “simple”. The cation and anionic components of omnipresent salts each have specific ways of interacting with water, and likewise specific ways of interacting with an organic molecule (or macromolecule) also present in solution. This presentation will center around our latest findings from studies into how model systems involving simple hosts, salts and water interact to engender phenomena such as the Hofmeister effect and the reverse Hofmeister effect, and how these non-covalent interactions can be harnessed to bring about control of chemical processes.
