  • Stable activable tracers for environmentally significant organic molecules

    Creator:
    Ghannam, Lina M.
    Abstract:
    The need for field and laboratory studies of the physical and chemical behavior of environmentally significant organic molecules often poses problems because of the toxicity of the chemical and the difficulty of detecting it at environmentally significant concentrations. Two dysprosium tracers, dysprosium (III) trisacetylacetonate trihydrate and dysprosium(III) trisdibenzoylmethane monohydrate, were...

  • Semi-volatile organic compounds as molecular markers for atmospheric and ecosystem transport

    Creator:
    Genualdi, Susan A.
    Abstract:
    The use of semi-volatile organic compounds (SOCs) as molecular markers to identify the contributions of regional and long-range atmospheric transport, as well as current and historic sources, and contaminant deposition in remote ecosystems of the Western U.S. was investigated. Trans-Pacific air masses influenced by Siberian biomass burning events had elevated...

  • The role of iron-oxides in U(VI) adsorption and the kinetics of contaminant organic reduction

    Creator:
    Logue, Brian A.
    Abstract:
    Contaminant transport in ground water is an important environmental process that affects a host of natural systems. Transport of contaminants is affected by many processes, including aqueous complexation, adsorption, and redox reactions. One of the most important components of an aquifer that controls transport is iron-oxide. In this study, the...

  • Organic/Inorganic Hybrid Materials of Uranyl Peroxide Clusters and Uranium Minerals

    Creator:
    Neal, Harrison A.
    Abstract:
    Frontier research of non-aqueous actinide clusters is discussed. Since the inception of the uranyl peroxide clusters over the last decade, they have only been synthesized and characterized as solid crystals and in aqueous solution. This thesis provides thorough characterization of aqueous uranyl clusters and the first demonstration of uranyl cluster...

  • Polycyclic Aromatic Hydrocarbons in Atmospheric Fine Particulate Matter: Beyond the Priority Pollutant List

    Creator:
    Kramer, Amber L.
    Abstract:
    Atmospheric fine particulate matter (PM2.5) has been linked to the death of 7 million people per year around the planet. The organic portion of PM2.5 is responsible for increases in oxidative stress, inflammation, mutation and carcinogenesis. Anthropogenic activity releases more organic material into the atmosphere, and has increased the amount...

  • Synthesis and Characterization of Novel Metal-Oxo Clusters as the Building Blocks in Nature and Synthesis

    Creator:
    Amiri, Mehran
    Abstract:
    Metal-oxo clusters can be described as soluble pieces of metal-oxide frameworks. Metal-oxo clusters are also the building blocks for the Metal-Organic Frameworks (MOFs) and coordination polymers. A better knowledge of metal-oxo clusters helps fundamentally understand geosciences, molecular engineering, catalysis, single-molecule magnetism, and MOFs for synthesis, design, and modification of these...

  • Measuring in situ biotransformation in BTEX-contaminated groundwater

    Creator:
    Alumbaugh, Robert E.
    Abstract:
    Benzylsuccinate (BSA), methylbenzylsuccinate (methylBSA), and ethylbenzylsuccinate (ethylBSA) are unambiguous anaerobic biotransformation products from toluene, xylenes, and ethylbenzene decay, respectively, and may be used to indicate intrinsic bioremediation is occurring at hydrocarbon-contaminated sites. In order to improve upon current methods that detect and quantify anaerobic hydrocarbon metabolites in field samples, solid-phase-extraction...

  • Measuring in situ reductive dechlorination rates in trichloroethene-contaminated groundwater

    Creator:
    Hageman, Kimberly J.
    Abstract:
    Trichloroethene (TCE) is the most frequently detected organic contaminant in groundwater, is classified as a probable human carcinogen, and exhibits toxicological effects on the human endocrine, immune, developmental, and reproductive systems. While significant research efforts have been devoted to the development of strategies for remediating TCE-contaminated groundwater, their advancement is...

  • Studies of Structurally Complex Thin Film Oxides for Electronic Materials

    Creator:
    Fast, Dylan Braucht
    Abstract:
    In this dissertation, the structure and electronic properties of multiple metal oxide thin films are characterized and presented. Prompt inorganic condensation (PIC) of metal-oxo and –hydroxo clusters was evaluated as a technique for making metal oxide clusters in two separate studies. The first focuses on the synthesis of lithium niobate...

  • 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...
