  • Removal of Radioactive Strontium, Iodine, and Uranium from Contaminated Groundwater : Sorption Processes and Properties

    Creator:
    Leonard, Mary E.
    Abstract:
    Iodine-129 is a key risk driver at sites where nuclear materials have been fabricated or processed, and it is a predominant isotope of concern in long-term waste storage strategies. I-129 exists primarily as iodate in the subsurface at the Hanford Site in south-central Washington State. Between 15 and 40% of...

  • 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...

  • Prediction and Measurement of Polycyclic Aromatic Hydrocarbons (PAHs) Transformation Products in the Environment.

    Creator:
    Titaley, Ivan A.
    Abstract:
    Polycyclic aromatic hydrocarbons (PAHs) are a group of environmental contaminants consisting of fused benzene rings. Parent-PAHs, methylated-PAHs (MPAHs), and PAHs with molecular weight of 302 a.m.u (MW302-PAHs) are considered as unsubstituted-PAHs. These unsubstituted-PAHs undergo transformation reactions resulting in the formation of PAH-transformation products (PAH-TPs), or substituted-PAHs, including nitrated-, oxygenated-, and...

  • New multi-functional chalcogenides for photovoltaic and thermoelectric materials

    Creator:
    Heo, Jaeseok
    Abstract:
    The subject of this PhD thesis is part of a research domain of great present interest in new semiconductor materials for photovoltaic and thermoelectric applications. This domain contains the elaboration and the study of both Cu-based chalcogenides bulk and thin-film samples, driven by materials design principles. One of the most...

  • The kinetic and radiolytic aspects of control of the redox speciation of neptunium in solutions of nitric acid

    Creator:
    Precek, Martin
    Abstract:
    Neptunium, with its rich redox chemistry, has a special position in the chemistry of actinides. With a decades-long history of development of aqueous separation methods for used nuclear fuel (UNF), management of neptunium remains an unresolved issue because of its not clearly defined redox speciation. Neptunium is present in two,...

  • Use of Targeted and Non-Targeted Analysis to Study Complex PAH Environmental Mixtures

    Creator:
    Chibwe, Leah
    Abstract:
    Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous contaminants formed from the incomplete combustion of organic material. These contaminants are of concern because of their widespread presence in the environment and toxic properties. In addition, PAHs encompass a class of diverse compounds with varying physicochemical properties and exist in the environment as...

  • 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...

  • Solvent Extraction Behavior of Mixed N, O-Donor Ligands for Separation of Trivalent f-Elements

    Creator:
    Karslyan, Yana
    Abstract:
    Nowadays selective separation processes are sought after more than ever before. They are indispensable to meet the growing demand for individual rare earth elements, minor actinides partitioned from fission-produced lanthanides, as well as, overall, more concentrated and high-purity products. This research focuses on such separation techniques as solvent extraction which...
