Analysis of Organochlorine Pesticides (OCPs) in Gray Whale Scat as an Alternative Method of Toxicant Quantification in Cetaceans

Creator:: Kutnerian, Amy M.
Abstract:: A method was developed to quantify organochlorine pesticides in whale scat. This method would ideally replace analysis of pesticides in blood and tissue samples, which are difficult to acquire. Scat samples were collected from one stranded gray whale and three live whales. The samples were extracted with pressurized liquid extraction,...

Quantification of Lithium via Redox Titration and pH Titration – A Method Comparison

Creator:: Hebert, Joseph J.
Abstract:: Lithium serves an unparalleled role for high energy-density storage applications and is vital for the continued advancement of the world economy. However, global supply is heavily reliant on lithium deposits situated in select locations, creating unpredictability in the price and concerns for the sustained production of the resource. Additionally, future...

Synthesis and SERS : Reproducible Nanostar Plasmons and a Study of Optical Enhancement

Creator:: Ramsey, Jacob D.
Abstract:: Gold nanostars are a relative newcomer to the nanoparticle scene, and their unique properties make them very desirable for spectroscopic applications. These nanoparticles, with their sharp tips, create electric field enhancements that interact with light in an advantageous way. This Thesis outlines our in-depth study of gold nanostar synthesis, the...

New Inorganic Pigments from Mineral Structures

Creator:: Schettini Mejia, Carlo A.
Abstract:: The discovery of new blue pigments is a field of great interest, as commercially available pigments present properties that make them undesirable such as poor sustainability, cost, and stability. By researching solid solutions with the melilite structure, we discovered a new solid solution Sr2Zn1-xNixGe2O7, with 0.1 ≤ x ≤ 0.6,...

Isolation and Identification of Indole Metabolites from Pseudomonas fluorescens NZI7

Creator:: Vergis, John M.
Abstract:: Pseudomonas fluorescens NZI7 was first isolated from a New Zealand mushroom farm in 2001. This Gram-negative bacteria can cause brown blotch disease in the basidiomycete mushroom Agaricus bisporus. P. fluorescens NZI7 can also repel grazing by the nematode Caenorhabditis elegans, a natural predator of P. fluorescens NZI7. Potentially implicated in...

High Resolution Spectroscopy of Bicyclo[1.1.1]pentane

Creator:: Martin, Matthew A.
Abstract:: The strained carbon ring, bicyclo[1.1.1]pentane, was synthesized by a reaction between 1-(phenylsulfanyl)bicyclo[1.1.1]pentane, prepared from propellane, and Raney nickel. Infrared spectra were recorded at a resolution of 0.0015 cm-1, a resolution significantly better than previous measurements, 0.06 cm-1. A single fundamental band was analyzed to determine the ground state and excited...

Effects of Estrogen Receptor Blockade on Skeletal Response to Alcohol in Ovariectomized Rats

Creator:: Wagner, Lindsay A.
Abstract:: Heavy alcohol consumption reduces peak bone mass in growing rodents and can lead to bone loss in both adult rats and humans. In contrast, moderate alcohol consumption appears to have a bone sparing effect in post-menopausal women. Alcohol has been reported to increase aromatase activity and influence estrogen receptor (ER)...

Adapting the Methylene Blue Sulfide Detection Method for Use in a Microfluidic in-situ Monitoring Device

Creator:: Monares, Shane W.
Abstract:: Sulfide is an important species to measure in environmental water samples. The spectrophotometric detection method for reduced sulfur species (sulfide) based on generation of methylene blue was adapted to work in an apparatus utilizing microfluidic PDMS mixing and observation cells with flow channels in the 100 μm range. The benefits...
