  • 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...

  • 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...

  • Unlocking Water's Potential for Energy Storage: Abundant Materials for a Ubiquitous Problem

    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,...

  • 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...

  • 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....

  • 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...

  • Functional transition metal oxides : structure-property relationships

    Creator:
    Smith, Andrew E.
    Abstract:
    Transition metal oxides are an important class of materials for the wide variety optical, electrical, dielectric, magnetic, and thermal properties observed. Their unique structure-property relationships allow for property tuning and often provide insight into the fundamentals of chemistry. The work in this thesis was focused on the design, synthesis and...

  • 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...

    Creator:
    Xu, Yunkai
    Abstract:
    The grand plan of carbon neutralization and COP26 in Glasgow require a quick shift of energy sources from conventional fossil fuel to a more renewable substitute such as wind, or solar energy. However, the intermittency of those renewable energy sources does not meet the demand of the energy, which requires...

  • Tracking Photoinduced Primary Events with Femtosecond Stimulated Raman Spectroscopy and Calculations

    Creator:
    Wang, Yanli
    Abstract:
    Femtosecond stimulated Raman spectroscopy (FSRS) is a powerful ultrafast technique which can track photoinduced excited state structural events on femtosecond (fs) to picosecond (ps) timescales. In addition to high temporal and spectral resolutions, FSRS provides a broad spectral window from ca. 100—2000 cm-1 for detection, enabling the direct mapping of...
