In one project, with Professor Nien Hwa Linda Wang, on "Experimental Probing and Molecular Simulations of Key Sorbent-Solute-Solvent Interactions in Chiral Separations," we study how ultrathin films of some polysaccharide-based polymers at solid interfaces can "recognize" and separate in chromatographic columns racemic mixtures of enantiomers, which otherwise they have identical physical and chemical properties.
In a second project, in collaboration with Professor David S. Corti, we study the "Aqueous Dispersion Stability of Inks and Ink-Like Model Colloidal Dispersions." The main goal of the detailed experimental and theoretical studies is to improve understanding of the inter-particle forces which cause the dispersions of colloidal particles or nanoparticles to agglomerate, or to remain stable. The project aims in developing innovative theories, models, and simulations, and industrial guidelines on how to control dispersion stability, and ultimately to new ways of making improved inks.
In a related project, in collaboration with Professor David S. Corti, we study the colloidal stability of dispersions of hydrate particles formed by complexes of hydrocarbons and water. Such hydrates may lead to plugging of pipelines containing hydrocarbons during the production stages, and should be avoided. This project is aimed at the “flow assurance,” or safety and environmental aspects of oil and natural gas production.
