  • Examination of low-lying rovibrational states of D₃[subscript h] oblate top molecules using high resolution FTIR and coherent anti-Stokes Raman spectroscopies

    Creator:
    Kirkpatrick, Robynne
    Abstract:
    Interesting rovibrational characteristics of two D_(3h) oblate symmetric top molecules were studied. Hamiltonian models for the fine rovibrational level structure of [1.1.1]propellane (propellane) were obtained for many low-lying modes. Ground state parameters (GSP) that are not exclusively K^(2n) dependent were obtained. Initially, the GSP were used in conjunction with density...

  • Synthesis and Solution Behavior of Tetravalent Metal Clusters with Ammonium Counterions

    Creator:
    Brown, Jessica C.
    Abstract:
    Global interest in reducing carbon emissions by use of alternative energy sources makes nuclear energy production and the impacts of the nuclear energy cycle relevant. Studying the aqueous speciation of tetravalent metals commonly used for nuclear energy (uranium, thorium, plutonium) can inform us of general metal properties and their behavior...

  • Detection techniques for biomolecules using semi-conductor nanocrystals and magnetic beads as labels

    Creator:
    Chatterjee, Esha
    Abstract:
    Continued interest in the development of miniaturized and portable analytical platforms necessitates the exploration of sensitive methods for the detection of trace analytes. Nanomaterials, on account of their unique physical and chemical properties, are not only able to overcome many limitations of traditional detection reagents but also enable the exploration...

  • Structure-property relationships of YbFe₂O₄-type layered transition metal oxides

    Creator:
    Grajczyk, Rosa
    Abstract:
    The structure–property relationships of solid solutions within the YbFe₂O₄ family of compounds have been studied in relation to their optical, dielectric and magnetic properties. This family of compounds is of recent interest because of the trigonal bipyramid coordination that is rarely observed in transition metal oxides. The systematic study of...

  • Cation Substitution Effects in Complex Transition Metal Oxides

    Creator:
    Duell, Brett A.
    Abstract:
    Understanding structural evolution in solids as composition changes is essential to materials properties prediction. Such structure-properties relationships are the theme of solid state chemistry. Materials scientists and chemists have utilized an abundance of simple crystal structures to enhance understanding of chemical and structural origins of properties in materials for decades....

  • 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...

  • Structure-property Relationships of Transition Metal Oxides Containing Precious Metals

    Creator:
    Hapuraja Pathirannehelage, Vidhara H. P.
    Abstract:
    This dissertation presents a study of structure-property relationships within 3d/4d metal oxides containing precious metals through detailed structure refinements using high-resolution neutron and X-ray diffraction data along with exploration of the resultant properties. Oxides of 4d or 5d transition metals tend to show new topological phases due to significant spin-orbit...

  • Studies toward the total synthesis of azaspiracid-1

    Creator:
    Kuiper, Damien L.
    Abstract:
    Azaspiracid has generated an enormous amount of scientific interest in the fourteen years since its initial discovery. The structure contains a 6,5,6 bis-spiroketal, a [3.3.1] bicyclic ketal and a 6,5-spiroaminal linkage as key moieties. With 9 rings, 20 stereocenters and three alkenes, the azaspiracid immediately attracted the interest of the...

    Abstract:
    The variegated aqueous chemistries of metal cations are applied to the design and synthesis of non-toxic solution precursors suitable for additive printing of large-area oxide electronics. Polycondensation behaviors of aqueous Al+3 and PO4 +3 are manipulated in the deposition of atomically smooth amorphous aluminum oxide phosphate (AlPO) dielectric films. AlPO...

  • Metal-oxo Clusters as Novel Photolithographic Materials: How Understanding the Chemistry of HafSOx Informs Next-Generation Patterning Systems

    Creator:
    Amador, Jenn M.
    Abstract:
    The solution chemistry and kinetic behavior of hafnium peroxy sulfate solutions ("HafSOx") is described in terms of peroxide content and solution speciation. Additionally, thin film behavior, including thermal behavior and solubility, is characterized, and a mechanism of patterning is presented, as well as parameters that should be considered when looking...
