  • Luminescent sulfides and solution-deposited oxide thin films

    Creator:
    Anderson, Jeremy T.
    Abstract:
    Solid state luminescent sulfides are prepared as powders in order to elucidate the relationship between structure and light emission. While the sulfides studied in this dissertation are known phosphors, materials are investigated in a variety of new ways. Elementary properties and structures of MgS are reviewed, and preparation of MgS...

  • Precursor Chemistry and Film Structure and Properties via Solution Deposition

    Creator:
    Huang, Yu
    Abstract:
    Chemistry of preparing dense film from solution deposition is explored with several cases in this thesis. Surface dense structure, conversion at melting point, and ion exchange in aqueous solution are the main topics covered here for the thin films of aluminum oxide phosphate and tin dioxide. Thin film density, optical...

  • A seasonal study of sediment reworking by Neotrypaea californiensis in Yaquina Bay, Oregon

    Creator:
    Fritz, Cara E.
    Abstract:
    A year-long field study was undertaken to investigate the influence of a number of physical and biological factors, specifically temperature, organic carbon content, and shrimp population dynamics on sediment reworking rates by the ghost shrimp Neotrypaea calforniensis. Because of its role as a structuring agent in estuaries along the West...

  • Subwavelength light confinement and quantum chaos in micro- and nano-structured metamaterials

    Creator:
    Govyadinov, Alexander A.
    Abstract:
    This dissertation concerns a broad range of unique phenomena related to the light propagation at nano- and micro-scales. To access the nano-domain, we introduce anisotropy-based waveguides with positive- and negative-index modes. These novel structures allow energy propagation in subwavelength regions and, in contrast to surface waves, have the mode structure...

  • Amorphous multi-component metals as electrode materials

    Creator:
    Cowell, E. William
    Abstract:
    The objective of this thesis is to provide an initial demonstration of two-terminal and three-terminal electronic devices employing amorphous multi-component metallic film (AMMF) electrodes. Such a demonstration is successfully achieved in the fabrication of metal-insulator-metal (MIM) diode and hot electron transistor (HETs) structures employing ZrCuAlNi AMMF electrodes. The ultra-smooth surface...

  • The synthesis, optical, and transport properties of SnZrS₃

    Creator:
    Harada, Daniel Ryan
    Abstract:
    Semiconducting materials which can be ambipolarly doped are highly desirable in many electronics applications, including use as solar cell materials. SnZrS₃ is being investigated for the possibility of ambipolar doping, with potential applications as a solar cell absorber layer. This dissertation covers the synthesis of SnZrS₃ and the related compound...

  • Killing spinors and affine symmetry tensors in Gödel's Universe

    Creator:
    Cook, Samuel A.
    Abstract:
    The existence of generalized symmetries of Maxwell's equations in Gödel's Universe is investigated. It is shown that their existence is in turn tied to the existence of certain spinorial objects called Killing spinors. The conformal algebra, corresponding to valence (1; 1) Killing spinors, for Gödel's Universe is discussed in detail....

  • Direct atom transfer vs. ring expansion in reaction of rhenium oxo complexes with cyclooctene epoxides and episulfides

    Creator:
    Khownium, Kriangsak
    Abstract:
    The rhenium (V) complex Tp'ReO₂ (Tp' = hydrido-tris-(3,5- dimethylpyrazolyl)borate), generated in situ from PPh₃ reduction of Tp'Re0₃, reacts with small ring heterocycles such as epoxides and episulf ides. The strained trans-cyclooctene ring provides an unusual thermodynamic bias against direct atom transfer, but trans-cyclooctene oxide still produces substantial amounts of trans-cyclooctene....

  • Advances in solid phase synthesis of neutral oligonucleotide analogues

    Creator:
    Wang, Haiyan, 1963-
    Abstract:
    A novel acyl protecting group for cytosine and adenine has been prepared from 4-( chloromethyl) benzoic acid. Reaction of the acid with morpholine produces 4-( 4-morpholinyl )methyl benzoic acid which is converted to it's acid chloride with thionyl chloride. This may be used to acylate cytidine and adenosine under standard...
