Donald M Zebolsky, PhD

Emeritus Associate Professor, Physical Chemistry

Don Zebolsky is interested in calculating volumes, enthalpies and solubilities for supercritical fluid mixtures. Calculations are with van der Waals type equations of state that replace the excluded volume term with hard sphere expressions, and add temperature-dependent attractive terms with molecular meaning. Computer programs are written to test these features and used to compare experimental data in the literature with predicitons and curve fits. Don Zebolsky is also trying to observe interactions in solution with differential scanning calorimetry and osmometry.
