Dilute Permanganate Preferentially Oxidizes Polyphenols Rather than Microbial Food: A Reinterpretation of a Common “Active Carbon” Measurement

Creator:: Christy, Isabel
Abstract:: “Active carbon” is a rapidly cycling soil organic carbon (SOC) fraction that acts as an energy and nutrient source for the microbial community. Dilute permanganate oxidation has been used to measure an “active carbon” fraction with the assumption that permanganate oxidation mimics enzymatic decomposition. Permanganate oxidizable carbon (PoxC) has become...

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,...

Relative influence of trans-Pacific and regional atmospheric transport of polycyclic aromatic hydrocarbons (PAHs) in the Pacific Northwest (PNW), USA

Creator:: Lafontaine, Scott
Abstract:: The relative influences of trans-Pacific and regional atmospheric transport on measured concentrations of polycyclic aromatic hydrocarbons (PAHs), PAH derivatives [Nitro- (NPAH) and Oxy-(OPAH)], organic carbon (OC), and Particulate Matter (PM) less than 2.5 μm in diameter (PM₂.₅) were investigated in the Pacific Northwest, USA in 2010-2011. Ambient high volume PM₂.₅...

Improvements in synthesis and response techniques of ion-selective sensors

Creator:: Pylypiuk, Nataliia
Abstract:: Two improvements to the established procedures for synthesis and response detection of ion-selective optical sensors (optodes) were introduced. The first improvement addresses the drawback of organic dye (optode-localized chromoionophore) photobleaching. This positively impacts fluorescence response and allows for (1) direct measurement of hydrogen ion activity upon binding with the dye,...

A Pyrone Diels–Alder Approach to Substituted Indoles and Carbazoles and the Synthesis of New Ropinirole Analogues

Creator:: Points, Gary L., III
Abstract:: Aromatic heterocycles are core structural motifs in natural products, pharmaceuticals and biological polymers. Indoles, in particular, represent a significant subclass of aromatic heterocycles, both in terms of sheer numbers, but also in biological and pharmaceutical relevance. As such, new methodologies for the synthesis of indoles represent an important and continually...

Expanding the Use of 19F NMR Spectroscopy in Per- and Polyfluoroalkyl Substance Analysis: Determination of Total Fluorine and Isomeric Distribution in Aqueous Film-Forming Foams

Creator:: Schaum, Andre F.
Abstract:: Aqueous film-forming foams (AFFFs) are significant sources of per- and polyfluoroalkyl substances (PFAS) in the environment. Current analytical methods that provide quantitative measures of individual PFAS in AFFFs, such as liquid chromatography – tandem mass spectrometry (LC-MS/MS), are often complicated, time-consuming, and expensive. Methods for total fluorine analysis, though quantitative,...

Detrital Influences on Soil Carbon Stabilization in Wet Temperate Forest Soils

Creator:: Pierson, Derek N.
Abstract:: Soils, with their potential to store and stabilize carbon (C), are an essential resource for sustaining forest productivity, as well as for efforts to reduce atmospheric C concentrations. Protecting existing soil C and harnessing the sequestration potential of our soils require an improved understanding of the processes through which soil...

The Local Structure of Functional Electroceramics

Creator:: Culbertson, Charles M.
Abstract:: This work investigates the relationship between the local structure and physical properties of a set of classical (MgTiO3, CaTiO3, SrTiO3, and BaTiO3) and complex ((1-x)Ba(Zr0.2Ti0.8)O3-x(Ba0.7Ca0.3)TiO3[BZT-BCT], Na0.5Bi0.5TiO3 [NBT]) perovskite electroceramics. The materials in this work were synthesized via standard solid state ceramic synthesis, the structure was investigated through a number of...

Development and Application of Mass Spectrometry-driven Methods for the Detection and Characterization of Biomolecular Signatures of Diseases

Creator:: Zandkarimi, Fereshteh
Abstract:: State-of-the-art, high-resolution mass spectrometry techniques for acquisition of metabolomic and lipidomic data coupled with advanced computational methods provide new opportunities for interpreting large and complex datasets and comprehending the underlying biological processes of diseases. Both metabolomics and lipidomics strive to obtain comprehensive analyses of small molecules, i.e., metabolites and lipids,...

Defining PAH and Oxygen-substituted PAH-dependent Developmental and Adult Toxicity in Zebrafish

Creator:: Knecht, Andrea L.
Abstract:: Polycyclic aromatic hydrocarbons (PAHs) and oxygen-substituted PAHs (OPAHs) are environmental contaminants present in urban air, dust, soil and water resulting from incomplete combustion of organic materials or fossil fuels; found in crude oil and coal; and formed through photoxidation or biotransformation of microbial. It is widely recognized that PAHs pose...
