Active site studies and design of ligands for affinity column separation of 2,5-dihydroxyacetanilide epoxidase (DHAE) I and II

Creator:: Allen, Scott E.
Abstract:: A series of compounds, 7-8 and 20-25, were tested as competitive inhibitors of 2,5-dihydroxyacetanilide epoxidase I (DHAE I) and DHAE II. A Hammett plot was constructed for each enzyme to determine the effect of electron density on inhibition. DHAE I gave a linear, highly correlated plot (r²=0.91) that signifies the...

Human exposure to polycyclic aromatic hydrocarbons : global cancer risk and metabolism

Creator:: Motorykin, Oleksii
Abstract:: In recent decades, there has been increased attention on human exposure to, and subsequently toxicity of, Polycyclic Aromatic Hydrocarbons (PAHs). PAHs are widespread organic pollutants and some have been shown to be toxic, carcinogenic and mutagenic. This research was focused on understanding the link between global PAH emissions and lung...

Design, construction, and characterization of a six-electrode, direct current, variable length plasma source for atomic emmission spectroscopy

Creator:: Shields, James Phillip
Abstract:: The variable length, six-electrode plasma source for atomic emission spectroscopy described here is operated from three compact, simple, and inexpensive direct current power supplies. The vertical arcs formed between the three electrode pairs completely entrain the sample and are typically operated at 40 V and 20 A. Three concentric quartz...

Stereoselective synthesis & application of enantioenriched main group α-haloalkyl organometal reagents

Creator:: Emerson, Christopher R.
Abstract:: Sulfoxide-ligand exchange (SLE) and asymmetric halogen-metal exchange (AHME) processes were separately examined for the enantioselective synthesis of functionalized alpha-haloalkylmetal (carbenoid) reagents. Carbenoids derived from SLE were used to effect stereospecific reagent-controlled homologation (StReCH) of boronic esters and those generated via AHME were engaged in Darzens-type chemistry with aldehydes. Abstract for...

Functional transition metal oxides : structure-property relationships

Creator:: Smith, Andrew E.
Abstract:: Transition metal oxides are an important class of materials for the wide variety optical, electrical, dielectric, magnetic, and thermal properties observed. Their unique structure-property relationships allow for property tuning and often provide insight into the fundamentals of chemistry. The work in this thesis was focused on the design, synthesis and...

Local scale spatial and temporal variation in wet deposition of persistent organic pollutants by snow

Creator:: Walsh, Christopher D.
Abstract:: The objective of this research was to assess the variability of POP deposition by snow on a 10 km spatial scale by measuring the POP concentrations in fresh-fallen snow from remote alpine sites. Samples of pre-metamorphic snow were concurrently collected from three remote alpine sites, of matched altitude and exposure,...

Slow processes in gas-solid chromatography

Creator:: Burns, Walter Frederick
Abstract:: Gas-solid chromatography often has asymmetrical elution peaks. This is attributed to nonlinear isotherms, multi-energy adsorption sites, and slow processes. This study utilized a stopflow gas chromatograph with various NaOH and NaCl modified aluminas as adsorbents and methane as adsorbate to determine the influence of surface area and pore volume distribution...
