Accomplishments

2. Fourier transform infrared spectroscopy coupled via a flow cell to gel permeation, normal phase and reversed phase chromatography employing microbore columns.

3. Application of packed microbore columns to supercritical fluid chromatography of organic acids and bases employing highly deactivated stationary phases.

4. Sample preparation utilizing supercritical fluids for trace analysis of organic analytes in solid, semi-solid, and liquid matrices.

5. Development of Fourier transform infrared, mass spectroscopy, electron capture and sulfur chemiluminescence detection for quantitative supercritical fluid chromatography.

6. Supercritical fluid fractionation and identification of oligomers and additives in polymeric materials found in fibers, pharmaceuticals, explosives, etc.

7. In situ generation of metal and ceramic domains in polyimides. These microcomposite materials have desirable magnetic, electrical, and reflective properties.

8. Mechanism of metal-polymer adhesion in titanium sputter-coated polyester and aluminum vapor deposited polyester.

9. Synthetic inorganic models for vitamin B₁₂ and the manganese site in chlorophyl. Factors leading to small molecule (O₂, NO) activation were established.

10. Liquid metal alloy substitute for mercury discovered which has low solidification temperature, is nontoxic, and exhibits good electrical conductivity.
