Development of automated flow injection apparatus and a novel flow cell for chemi- and bioluminescence determinations

Creator:: Gander, Stuart C.
Abstract:: A practical and versatile instrument has been developed both to optimize the chemistry of bio- and chemiluminescence reactions and to measure ultra-trace quantities of associated analytes. The instrument consists of a pneumatic flow injection system linked to a detection cell and a signal processing and readout system. The disk-like cell...

Fluorinated and deuterated surrogates for quantifying microbial transformation of chlorinated ethenes and ethanes in anaerobic groundwater

Creator:: Ennis, Elliot G.
Abstract:: Chlorinated aliphatic hydrocarbons (CAHs) such as vinyl chloride (VC) and 1,-2 dichioroethane (DCA), are wide-spread groundwater pollutants found at many contaminated field sites around the world. Quantitative tools are needed to determine the in situ rates of VC and DCA transformation to ethene in contaminated groundwater. The objective of this...

The synthesis and spectral properties of 2,4-dioxabicyclo [3.3.1] nonanes

Creator:: Provant, Stephen Glenn
Abstract:: 3-Methyl-2,4-dioxabicyclo [3.3.1] nonane and 7-hydroxy-3-methyl-2, 4-dioxabicyclo [3.3.1] nonane were synthesized by the method of Croxall, Glavis and Neher, although in low yields. The structure of both compounds was proven by analytical methods and analysis of their spectral properties. Tentative configuration of C-3 in both compounds was assigned on the assumption...

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...

The effect of oxide impurity on the conductivity of potassium chloride

Creator:: Kouts, Daberath
Abstract:: Direct current conductivity measurements on KC1:O[superscript]= crystals were used to determine an enthalpy of 0.42 ev for the dissociation for anion-vacancy-oxide ion complex. The entropy of dissociation was found to be approximately -4x 10⁻⁴ev deg⁻¹. The intrinsic "activation" energy was found to be 1.91 ev as compared to 1.95 ev,...

Heats of immersion and swelling of quaternary ammonium complexes of montmorillonites

Creator:: St. Clair, Akos Dominic
Abstract:: Heats of immersion were obtained for four different organophilic clay complexes in a series of normal alcohol-heptane mixtures with alcohols of increasing chain length. The immersion calorimeter employed was the Dewar type with a sensitivity of approximately 5 x 10⁻⁵°C. Gel volumes were determined for two of the clay complexes...

Employing capillary electrophoresis as a separation method for pharmaceutical analysis

Creator:: Lessard, Laura L.
Abstract:: Capillary electrophoresis as a technique has many applications in a broad range of fields including forensics, environmental analysis, and biological analysis and as a separation method for samples such as oligonucleotides, peptides, proteins, and pharmaceuticals. The research conducted herein is for the antibiotic pharmaceutical ciprofloxacin HCl and three impurities. Sample...

The reaction between O-ions and F centers

Creator:: Staible, Thomas Fredrick
Abstract:: The photochemical reaction between O⁻ ions and F centers was investigated. The activation energy was determined by the Arrhenius law to be 0.10 + 0.04 eV for temperature below 180°K. The diffusion of alpha centers towards the oxide ion was eliminated as the rate limiting step and the low trapping...

A continuous amperometric monitor for aqueous sulfite solutions using bipolar current readout

Creator:: Porter, Miles John
Abstract:: A continuous amperometric monitor for aqueous sulfite solutions has been developed employing the electro-oxidation of sulfur (IV) in 0. 1 M sulfuric acid at a glassy carbon test electrode. The monitor employs a hydrodynamic flow cell, in which the solution stream enters the cell through an orifice impinging on the...
