  • The development of aminal radicals for the synthesis of nitrogen-rich natural products

    Creator:
    Schiedler, David A.
    Abstract:
    Organic compounds which contain one or more nitrogen atoms are especially important as they are disproportionately represented among biologically active molecules. As a result, significant effort has been focused on the development of methods for the synthesis of nitrogenous molecules. We identified the aminal as an under-explored functional group. Despite...

  • Studies on copper metabolism in the cotton rat Sigmondon hispidus texianus

    Creator:
    Milne, David Bayard
    Abstract:
    The effects of different levels of copper in the diet on growth rates, blood and liver copper concentrations, hemoglobin levels, and cytochrome c oxidase activities were determined in the cotton rat. The response of the cotton rat to different levels of copper was analagous to that of the common laboratory...

  • 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...

  • Substitutional Effects on the Electromechanical Properties of Lead-free, Piezoelectric (Na₀.₅Bi₀.₅)TiO₃-BaTiO₃ (NBT-BT)

    Creator:
    McQuade, Ryan R.
    Abstract:
    This work investigates the effect of cation substitution on the properties of the lead-free, solid solution (Na₀.₅Bi₀.₅)TiO₃-BaTiO₃ (NBT-BT). Substitution into NBT-BT increases disorder and increases the relaxor ferroelectric properties. These relaxor ferroelectric materials show large piezoelectric strains that can be utilized in actuator applications. Ceramic samples were prepared using standard...

  • A reinvestigation of the molecular structure of cyclohexane-1,4-dione by electron diffraction

    Creator:
    Johnson, Robert David
    Abstract:
    We have investigated the gaseous structure of cyclohexane- 1,4-dione via electron diffraction. The large amplitude motion, as suggested from spectroscopic, dipole moment and earlier electron diffraction data was studied. The structure was refined in two types of models: a single "distorted boat" conformer, and a model comprised of a superposition...

  • Preparation and characterization of polymer-SiO₂ hybrids

    Creator:
    Ferguson, Morgan L.
    Abstract:
    In a search for designed materials that mimic those found in biological systems, combining polymers with inorganic materials in sol-gel chemistry processes has gained momentum in the research world since the 1990's. This work methodically investigated the properties of several related polymer-SiO₂ hybrids prepared by a simple methodology that could...

  • Galvanostatic control of ion selective electrodes with the solvent polymeric membrane

    Creator:
    Perera, Hasini R.
    Abstract:
    Detection technique that proposed utilizing electrochemically controlled, reversible ion extraction into polymeric membrane in an alternating galvanostatic/ potentiostatic mode was introduced. This method is studied in detail to comprehend the advantages of the novel sensor (pulstrode) compared to the potentiometric ion selective electrode (ISE), studies included possible applications and limitations....

  • Approaches to the total synthesis of verrucarol

    Creator:
    Hill, David E. (David Edwin) 1954-
    Abstract:
    Verrucarol is the sesquiterpene portion of a number of macrocyclic di- and triesters of potential medicinal importance. In this study, a novel approach to the synthesis of this fungal metabolite is presented. An A-B-C route was investigated in which C-3 and C-4 of the C-ring were emplaced using a [2+2]...

  • Organic Crystalline Solids : Investigating their Capability, Storage Mechanism and Structural Evolution in Dual-Ion Batteries

    Creator:
    Rodríguez Pérez, Ismael A.
    Abstract:
    Widespread installation of renewable energy sources, such as wind and solar, has been delayed by the lack of suitable stationary energy storage solutions. Current large-scale technologies, such as pumped hydro and compressed air, are geographically restricted. This is where electrochemical energy storage - batteries or hybrid capacitors can play a...

    Creator:
    Leonard, Daniel P.
    Abstract:
    Water is an absolute necessity for life as we know it. It provides a useful medium in which chemical reactions take place that allowed for the development of single cellular organisms. When combined with the evolutionary accident that was pho- tosynthesis, water became not only a useful medium chemical reactions,...
