  • Electrochemical Reactions in Aqueous Batteries with Anionic Charge Carriers

    Creator:
    Gallagher, Trenton C.
    Abstract:
    In this dissertation, the primary objective is to discover more sustainable electrode materials and study new reaction mechanisms using aqueous electrolytes. The first study conducted reveals a reversible conversion reaction from copper to Cu2CO3(OH)2. The reaction mechanism uses OH- and CO32- as charge carriers at the cathode. The results open...

  • Synthesis and Characterization of Novel Metal-Oxo Clusters as the Building Blocks in Nature and Synthesis

    Creator:
    Amiri, Mehran
    Abstract:
    Metal-oxo clusters can be described as soluble pieces of metal-oxide frameworks. Metal-oxo clusters are also the building blocks for the Metal-Organic Frameworks (MOFs) and coordination polymers. A better knowledge of metal-oxo clusters helps fundamentally understand geosciences, molecular engineering, catalysis, single-molecule magnetism, and MOFs for synthesis, design, and modification of these...

  • New Inorganic Pigments from Mineral Structures

    Creator:
    Schettini Mejia, Carlo A.
    Abstract:
    The discovery of new blue pigments is a field of great interest, as commercially available pigments present properties that make them undesirable such as poor sustainability, cost, and stability. By researching solid solutions with the melilite structure, we discovered a new solid solution Sr2Zn1-xNixGe2O7, with 0.1 ≤ x ≤ 0.6,...

  • Electrolyte Design: Improving Capacity and Structural Stability of Electrodes

    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...

  • 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...

  • Designing Dielectric Materials through Complex Metal Oxides

    Creator:
    Nikkel, Jason W.
    Abstract:
    This dissertation demonstrated that the electrical properties of complex oxide-based perovskite materials could be controlled through the careful modification of both material composition and structure. This was first shown through the modification of lead zirconate titanate (Pb(Zr0.52Ti0.48)O3, PZT) solid solutions with bismuth indate (BiInO3, BI) where the relative stability of...

  • Properties of Large Superfluid Helium Droplets

    Creator:
    Alghamdi, Maha
    Abstract:
    In this dissertation, I describe the experimental investigation of large superfluid helium droplets. The goal and direction of this thesis is to facilitate the use of these droplets as part of our project ss-EDI. The overall scheme of ss-EDI is to dope proteins inside helium droplets and collect a diffraction...

  • Advanced Mass Spectrometry Techniques for Characterizations of Proteome and Lipidome Profiles of Osteosarcoma Cells

    Creator:
    Song, Zifeng
    Abstract:
    Mass Spectrometry has emerged as an analytical core technique in omics sciences, in particularly mass spectrometry has advanced the fields of proteomics, metabolomics and lipidomics in recent years. Mass spectrometric techniques have enabled the characterization and determination of abundance levels of a wide range of biomolecules at molecular and system-wide...

  • 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...

  • 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...
