Research Interests
Professor Eckert's research is focused at the interface between chemistry
and chemical engineering, where our interdisciplinary investigators
have unique capabilities to solve a variety of important technical and
societal problems, such as environmental control, solvent-free processing,
energy conservation, innovative separations (including bioseparations),
and novel materials.
The investigations encompass molecular thermodynamics, solution chemistry,
phase equilibria, chemical kinetics, homogeneous catalysis, supercritical
fluid processing, and separations. The group has developed new experimental
methods, including novel applications of modern instrumentation. Examples
of applications include wastewater purification, environmentally benign
solvents, supercritical fluid fractionation of polymers, purification
of monomers, separation of chiral compounds, composite materials manufacture,
hazardous waste detoxification, reactions in supercritical fluids, polymer
modification, polymer processing, and many others.
The group draws heavily on molecular chemistry, organic, inorganic,
analytical, and physical, for an understanding of intermolecular interactions
in solutions. We use these results, along with our data, to develop
methods for tailoring separation and reaction processes for specific
applications. Often these methods are applied also for process design
and economic feasibility evaluation.
