  • Quantitative determination of emerging contaminants, solvent stabilizers and fullerene nanomaterials, in biological and environmental systems

    Creator:
    Isaacson, Carl W.
    Abstract:
    To determine the impact of emerging environmental contaminants on human and environmental health, quantitative analytical methods are required. Analysis of emerging contaminants is hampered by their widely varying physical-chemical properties. Therefore quantitative analytical methods must be developed to determine the behavior of emerging contaminants in environmental systems. A quantitative analytical...

  • Determination of fluorochemicals in waste-dominated aqueous systems

    Creator:
    Huset, Carin A.
    Abstract:
    While fluorochemicals have been detected all over the world and in wastewater treatment plants, the effect of wastewater effluent on the receiving waters has not been evaluated. In the first study, the mass flow of fluorochemicals emanating from wastewater treatment plants along the Glatt River in Switzerland was evaluated. The...

  • Polarization spectroscopy and photodissociation studies of nitroaromatic compounds in the gas phase

    Creator:
    Abbott, James E.
    Abstract:
    The central purpose of this dissertation was to explore and expand the use of an uniform electric field for orientation and for subsequent spectroscopic investigation of asymmetric polar molecules in the gas phase. The systems of study were nitrobenzene (NB) and the nitrotoluene (NT) isomers. We were able to quantitatively...

  • Graphite intercalation compounds containing fluoroanions

    Creator:
    Katinonkul, Watcharee
    Abstract:
    New chemical synthesis strategies have been investigated for the preparation of acceptor-type graphite intercalation compounds (GIC's) with fluoroanions in order to obtain new materials and to develop a better understanding of the synthetic approaches and properties of the products. New GIC's containing borate chelate anion such as bis(oxalato)borate, CxB[OC(O)C(O)O]₂•δF, are...

  • Semi-volatile fluorinated organic compounds in Asian and Pacific Northwestern U.S. air masses

    Creator:
    Piekarz, Arkadiusz M.
    Abstract:
    Current studies suggest that perfluorinated organic compounds, such as fluorotelomer alcohols (FtOHs) in the troposphere, may be precursors of perfluorocarboxylic acids and perfluorosulfonates in remote regions. Fluorinated organic compounds were investigated in archived extracts collected from remote locations in Okinawa, Japan (HSO) and Mount Bachelor, Oregon (MBO) during the springs...

  • Studying fusion reactions for effect of PCN on heavy nucleus formation and for nuclear structure effects

    Creator:
    Naik, Radhika
    Abstract:
    The fusion reaction ²⁰⁸Pb (⁵⁰Ti, xn) ²⁵⁸⁻x Rf (x = 1-3) was studied to determine PCN (probability that the mononucleus system evolves to form a compound nucleus inside the fission saddle point) and to establish the value of Wsur (survival probability) for the given reaction experimentally. The fission excitation function...

  • The chemical nature of the extractives from the bark of red alder, alnus rubra, Bong

    Creator:
    Becker, Edward Samuel
    Abstract:
    The purpose of this investigation was to determine the nature of the extractives from red alder bark in an effort to discover the materials which cause the red stain in red alder wood. Samples of bark and wood were obtained and successively extracted with hexane, benzene, ether, ethanol, and hot...

  • Analysis of semi-volatile organic contaminants and their accumulation in remote aquatic ecosystems of the western US

    Creator:
    Ackerman, Luke K.
    Abstract:
    Many pesticides, polychlorinated biphenyls (PCBs), polybrominated diphenyl ethers (PBDEs), and polycyclic aromatic hydrocarbons are persistent, bio-accumulative, and toxic. These semi-volatile organic compounds (SOCs) can undergo atmospheric transport and deposition in cold, remote ecosystems. A better understanding of their accumulation in the fish of these ecosystems is important to better predict...

  • Development, validation and the application of a congener specific photodegradation model for PBDEs

    Creator:
    Zeng, Xia
    Abstract:
    The thermodynamic properties of 39 PBDEs have been calculated using Gaussian 03 on the B3LYP/6-31G(d)//B3LYP/6-31G(d) level. The PBDE congeners' enthalpies of formation increase with increasing number of bromines and show a strong dependence on the bromine substitution pattern. The effects of bromine substitution pattern have been quantitatively studied by GAM...

    Smits, Helmars
    Abstract:
    Studies towards the total synthesis of (−)-kendomycin (1), a bacterial metabolite with a unique molecular architecture and pronounced biological activity, are described. These studies resulted in the synthesis of advanced intermediate 208, containing all of the carbon atoms of 1. A Dötz annulation between alkyne 122 and novel chromium carbenoid...
