Chemistry Department Research AreasDr. Alan Bandy Analytical chemistry of industrial gases. Determination of true impurities in reagent gases used in the semiconductor industry. Emphasis on high tech methods such as Atmospheric Pressure Ionization Mass Spectrometry. Dr. Joe Foley Separation science, especially the fundamentals and biomedical/pharmaceutical applications of the following voltage- or pressure-driven separation techniques: capillary electrophoresis, electrokinetic chromatography, capillary electrochromatography, and micellar liquid chromatography. Within these techniques, we explore novel separation modes and surfactant aggregate pseudophases (micelles, vesicles, microemulsions); chiral separations; and physicochemical measurements. Dr. Kevin Owens Mass spectrometry research, including the development of matrix-assisted laser desorption/ionization (MALDI) time-of-flight mass spectrometry (TOFMS) techniques for use with biological and synthetic polymer systems, and the development of chemometric techniques for improved data analysis.
Dr. Alan Bandy Chemistry of sulfur in the atmosphere and its implications for global environment and climate.
Dr. Anthony Addison Design and synthesis of novel biomimetic and oligonuclear chelates of copper, nickel, iron and vanadium. Their interpretation by magnetochemical, electrochemical and spectroscopic methods, including electron spin resonance. CD and ESR spectroscopy and kinetics for elucidation of molecular architecture of derivatives (including NO) of oxygen-binding and electron-transfer heme- and non-heme iron metalloproteins of vertebrate and invertebrate origins.
Dr. Daniel King Development of inquiry-based labs for general and physical chemistry and incorporation of environmental data into lecture modules for general, physical and environmental chemistry. Dr. Jean-Claude Bradley The use of electric fields to toposelectively (site-selectively) modify isolated structures and colloidal materials, with a special interest in nanotechnological applications. Knowledge management of systems with an inherently dynamic relationship architecture, with a special interest in discovery-driven scientific research. Dr. Lynn S. Penn Construction of complex and controlled polymer brushes for functional surfaces; experimental study of diffusion into polymer brushes and comparison with theoretical predictions; surface and interface chemistry, including wetting and adhesion; real-time monitoring and quantitative analysis of chemical reactions and adsorption on surfaces. Dr. Robert Hutchins Development of new, selective synthetic methodologies including asymmetric synthesis (diastereoselective and enantioselective), especially directed toward amine derivatives; use of phosphorus chemistry in synthetic protocols; stereochemistry and conformational analysis of heterocyclic systems. Dr. Peter Wade Our work focuses on three main areas: 1) exploration of a newly discovered [3,3]-sigmatropic rearrangement in which O-allyl nitronic esters are thermally converted to g,d-unsaturated nitro compounds; 2) development and exploitation of a carbon-based hemiacetal mimic; and 3) exploration of cycloaddition reactions involving nitroethylene derivatives and novel nitrile oxides. Dr. Reinhard Schweitzer-Stenner Vibrational Spectroscopy, with an emphasis on Raman and resonance Raman spectroscopy; structure analysis of peptides in solution; understanding the coil state of peptides and proteins; protein folding of Heme proteins (cytochrome c, myoglobin, horseradish peroxidase), particularly the relationship between heme-protein interactions and function; theoretical modeling of ligand-receptor interactions and transmembrane signaling in mast cells. Theoretical & Computational Chemistry Dr. Carey Rosenthal Dr. Karl Sohlberg Theoretical and Computational Physical and Materials Chemistry, including first principles studies of: catalytic materials, kinetics and thermodynamics of hydrogen in catalytic materials, and surfaces of heterogeneous catalysts. Development of theoretical models for both electrical and mechanical molecular devices.
