  • Femtosecond Stimulated Raman Studies of Excited State Structural Events

    Creator:
    Tang, Longteng
    Abstract:
    Femtosecond stimulated Raman spectroscopy (FSRS) is an ultrafast vibrational technique which allows rapid collection of Raman spectra with simultaneously high temporal and spectral resolution. With the recent development of FSRS methodology, three FSRS techniques (conventional, tunable, and anti-Stokes) have been implemented in our laboratory to dissect the excited state structural...

  • 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...

  • Structure-property relationships of layered oxypnictides

    Creator:
    Muir, Sean W.
    Abstract:
    Investigating the structure-property relationships of solid state materials can help improve many of the materials we use each day in life. It can also lead to the discovery of materials with interesting and unforeseen properties. In this work the structure property relationships of newly discovered layered oxypnictide phases are presented...

  • 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...

  • 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...

  • Aqueous complexation of citric acid and DTPA with selected trivalent and tetravalent f-elements

    Creator:
    Brown, M. Alex
    Abstract:
    Carboxylic acids have played an important role in the field of actinide (An) and lanthanide (Ln) separations and the reprocessing of irradiated nuclear fuel. Recent bench-scale experiments have demonstrated that 3-carboxy-3-hydroxypentanedioic acid (citric acid) is a promising aqueous complexant that can effectively aid in the separation of transition metals from...

  • The chemistry and device applications of amorphous thin-film interfaces

    Creator:
    Knutson, Christopher C.
    Abstract:
    Solid-state amorphous materials show amazing promise in thin-film electronics. The interface-to-bulk ratio of thin films makes interfacial chemistries of these systems of utmost importance. Thin films of amorphous metals, dielectrics and semiconductors have novel chemistries that are not only based upon their elemental constituent makeup, but also based upon the...

  • Direct patterning of solution deposited metal oxides

    Creator:
    Stowers, Jason K.
    Abstract:
    Patterning of metal oxides typically involves a multi step process, involving depositing a resist, patterning that resist with some form of lithography, etching the oxide through the resist, and finally removing. This process can be simplified if the resist is removed and replaced with a metal oxide that can be...

  • Structure-property relationships of oxides with hexagonal AMO₃ and brownmillerite related structures

    Creator:
    Jiang, Peng
    Abstract:
    Transition metal oxides exhibit potential in various application fields due to the special d-electrons. Solid state chemistry focuses on discovering the structure-property relationships. The work in this thesis mainly discusses compounds with hexagonal or brownmillerite-type structure and their practical properties. Hexagonal YIn[subscript 1-x]Fe[subscript x]O₃ (x = 0-0.3, 0.7-1.0) phases have...

  • 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...
