The development and characterization of miniature spectrometers for measuring the redox status of environmental samples

Creator:: Cantrell, Kevin
Abstract:: A spectrometer, here denoted a Simple, Low-power, Inexpensive. Microcontroller-based or SLIM spectrometer. was developed that exploits the small size and low cost of solid-state electronic devices. This approach results in customizable spectrometers that are considerably less expensive and smaller than traditional instrumentation. The performance of the SLIM spectrometer was evaluated...

Reactions and stereochemistry of thiolato and sulfenato cobalt (III) complexes

Creator:: Herting, Daniel L.
Abstract:: This thesis describes a study of the synthesis, stereochemistry, and reactivity of cobalt(III) cysteinato (CyS) and related thiolato complexes. The preparation of [Co(en)₂CyS]⁺ resulted in a product solution containing a mixture of diastereomers in the ratio 2.3:1 (Δ:A). The isomers were separated by ion exchange chromatography, and their absolute configurations...

Atropisomeric 8,8'-biquinolyl derivatives : synthesis, properties and applications

Creator:: Milicevic, Selena D.
Abstract:: 7,7'-Dihydroxy-8,8'-biquinolyl (azaBINOL) was prepared from 7-hydroxyquinoline via N,N-dimethyl O-quinol-7-yl carbamate by directed ortho-metallation followed by FeCl₃-mediated oxidative coupling of the 8-lithioquinoline intermediate. Saponification of the resulting dicarbamate provided crystalline (±)-azaBINOL in 56% overall yield. 6,6'-Bis(dimethylaminocarbonyl)-7,7'-dihydroxy-8,8´-biquinolyl was prepared from the same dicarbamate by a double anionic-Fries rearrangement in 43% yield. 7,7'-Bis(diethylamino-carbonyloxy)-6,6'-diiodo-8,8´-biquinolyl...

Synthesis of novel ambifunctional atropisomeric 2,2',6,6'-tetrasubstituted biphenyls and investigation of their properties and organocatalytic activity

Creator:: Sephton, Mark Alan
Abstract:: Ambifunctional axially chiral 2,2',6,6'-tetrasubstituted biphenyls containing nucleophilic (or basic) functional groups juxtaposed with hydrogen-bond donors were synthesized and their properties studied. Applications for the prepared biaryls as potential organocatalysts for enantioselective carbon-carbon bond forming reactions were examined. Processes investigated included: aldol, Michael, nitroaldol (Henry), and Baylis-Hillman reactions. The novel amidoamine...

Polylcaprolactone-Based Microfluidic Devices : Fabrication Methods and Applications in Low-Cost Analytical Devices

Creator:: Heist, Christopher A.
Abstract:: The overall concept of reducing laboratory operations to a scale that fits on a single microfluidic chip has been an attractive area of research over the last several decades. Despite a surge in research, few commercial success stories have been written. Lab-on-a-chip technologies have the capability to be cost effective...

Investigating Low-Frequency Vibrations in Condensed Matter Using Time-Resolved Third-Harmonic Generation Spectroscopy

Creator:: Wang, Liang
Abstract:: In this thesis, I present a new method we developed to study low frequency (< 700 cm⁻¹) vibrational dynamics: Time-resolved third-harmonic generation (TRTHG) spectroscopy. Among a variety of vibrational spectroscopy techniques, TRTHG differentiates itself with robustness, versatility, and simplicity. In TRTHG experiment, that involves only two ultrashort laser pulses, the...
