  • 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...

  • Tuning Functional Properties of Pyrochlore and Related Oxides via Cation and Anion Substitutions

    Creator:
    Giampaoli, Gabriella C. S.
    Abstract:
    Inorganic structures play an important role in materials due to their versatility and diversity. A complete understanding of the structure of a material is vital to enhance the creation of new materials that fill voids in research. The rational design of these compounds is driven by the exploitation of structure-property...

  • Thin-Film Dielectric Structure of Spin-Coated ZrO2 from Aqueous Inorganic Solution

    Creator:
    Moreno Luna, Hidekel A.
    Abstract:
    An inorganic aqueous precursor for the deposition of ZrO2 thin films via spincoating was developed. Hydrolysis and condensation chemistries of ZrOCl₂·8H₂O were used as the principal reactions to guide the synthesis. Refractive index, n, for a film annealed at 300 °C at 550 nm was measured to be n=1.97 by...

  • Modeling Arctic melt ponds using a resolved ice model with GCM forcing

    Creator:
    Collins, Lee E.
    Abstract:
    The albedo of Arctic sea ice depends greatly on the formation of melt ponds. These ponds form in depressions on the ice as surface snow melts during the summer months, and their location is determined mainly by the initial snow topography. Using a high resolution sea ice model forced with...

  • 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...

  • Synthesis and characterization of aluminum oxide based materials - from molecule to device

    Creator:
    Wang, Wei
    Abstract:
    A scalable synthesis of the "flat" tridecameric inorganic cluster [Al₁₃(μ₃-OH)₆(μ-OH)₁₈(H₂O)₂₄]¹⁵⁺ has been realized by treating an aqueous aluminum nitrate solution with zinc-metal powder at room temperature. Single crystals and polycrystalline samples are readily obtained in yields exceeding 55% relative to the starting reagent Al(NO₃)₃. Products have been characterized by X-ray...

  • Hydrogen production via a sulfur-sulfur thermochemical water-splitting cycle

    Creator:
    AuYeung, Nicholas J.
    Abstract:
    Thermochemical water splitting cycles have been conceptualized and researched for over half a century, yet to this day none are commercially viable. The heavily studied Sulfur-Iodine cycle has been stalled in the early development stage due to a difficult HI-H₂O separation step and material compatibility issues. In an effort to...

  • 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...

  • 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...

    Bistrika, Alexander A.
    Abstract:
    As the world's power needs grow, the demand for power from renewable resources, such as wind or solar is increasing. One major drawback associated with these renewable resources is that the power output is dependent on environmental factors, such as cloud cover and wind speeds. This allows the possibility of...
