Academic InterestsGreen Chemistry Education
We have created a set of metrics to compare the green attributes of analytical methods and are applying this to analytical experiments. Educational materials for both the secondary and post-secondary level are being developed and we are investigating student attitudes toward social responsibility following exposure to green chemistry in the classroom.

Area(s) of ResearchGreen Chemistry
Applications of ResearchGreen Chemistry is defined as "the use of a set of principles that reduces or eliminates the use or generation of hazardous substances in the design, manufacture and application of chemical products."1 It's kind of Hippocratic Oath for chemists, a thought process for practicing chemists and a link to the goals of sustainability.
Green Chemistry and our expertise with supercritical fluid technology provide the basis for our research program. At elevated temperatures and pressures (i.e., above the critical point) compounds become supercritical fluids and possess properties intermediate between gases and liquids. These fluids dissolve solutes, yet have gas-like diffusivity and surface tension. Importantly, these properties can be varied as a function of temperature and pressure. Resulting chemical processes in supercritical fluids can have advantages of being faster and more selective, with minimal use of hazardous organic solvents.
Specifically, our research falls into three major areas: analytical separations, bioprocessing and green chemistry education.Analytical Separations. Virtually all laboratory samples require some type of separation prior to analysis. We are interested in analytical sample preparation (i.e., extraction) and high resolution chromatography methods. In the extraction area, we use supercritical fluid extraction (SFE) and a related technique, accelerated solvent extraction, for the isolation of selected organic compounds from a variety of sample types. Areas of active interest include studies on the role of diffusion in the extraction of solid samples, the isolation of additives (antimicrobials and growth hormone) from animal feeds and tissues and the determination of chemical contaminants that may migrate into foods during cooking. Another project is exploring the use of green solvents and chelating agents in separation processes. Our interests in high-resolution chromatography are in the use of supercritical fluid chromatography and high-temperature liquid chromatography for the characterization of complex samples. Bioprocessing. The next generation of biofuels includes cellulosic ethanol, but first the lignin sheath that surrounds the cellulose fibers must be isolated from the carbohydrate components. We are exploring the use of supercritical fluids, microwave irradiation and ionic liquids for the fractionation and hydrolysis of native grasses, distillers dried grain with solubles (DDGS) and soybeans. A major effort has just been initiated to use ionic liquids in the pyrolysis of prairie cordgrass into military jet fuel. We have used SFE to isolate a biodegradable polymer from the fermentation of DDGC. Finally, supercritical carbon dioxide is being utilized in refining beeswax and tanning leather.
