  • Dogs, Death, and Dietary Breadth: Insights into the Macroecology and Macroevolution of Canidae

    Creator:
    Tanis, Brian P.
    Abstract:
    The size, shape, and stability of a species’ dietary niche can both influence and reflect a variety of biological patterns, including species interactions, extinction risk, and ecosystem function. This is particularly apparent when dietary changes manifest at ecosystem and clade scales to profoundly affect macroecological and macroevolutionary trajectories. However, many...

  • Synthesis and Characterization of Alkylammonium Salts of Butyltin-Polyoxotungstates for Thin Film Functionalization

    Creator:
    Olsen, Morgan R.
    Abstract:
    Metal-oxo clusters are discrete, soluble pieces of bulk metal oxide. Cluster size, monodispersity, and chemical properties allow for potential use as solution-based precursors for functional metal oxide films. Classical monoalkyltin-oxo clusters are either charge neutral or stabilized by anions. The structure of Cs₄.₅H₂.₅[(BuSn)₃(α-SiW₉O₃₇)]*2H₂O enables its use in established ion exchange...

  • Synthesis and Solution Characterization of Metal-Oxo Photoresist Precursors

    Creator:
    Hutchison, Danielle C.
    Abstract:
    Metal-oxo clusters can be described as soluble pieces of metal-oxide frameworks. Currently, metal-oxo clusters are being considered as solution-based precursors for extreme ultraviolet (EUV, 13.5 nm) photoresist materials, which are a crucial component in the fabrication of microelectronic devices. Two different photoresist precursor systems have been investigated – alkyltin clusters...

  • Formation of hybrid supramolecular assemblies using biological molecules and transition metals

    Creator:
    Smith, Rachelle M. S.
    Abstract:
    Naturally occurring assemblies, such as DNA and proteins, utilize intermolecular forces (i.e H-bonding and van der Waals) to assemble. Utilizing these electrostatic interactions has only just started in the past five decades to be a tool used in synthetic chemistry in what is known as supramolecular chemistry. Supramolecular chemistry has...

  • Exploring the Iron Keggin Ion as a Prenucleation Cluster for Iron Oxide Nanoparticles Formation

    Creator:
    Sadeghihosseinabadi, Omid
    Abstract:
    Iron oxide materials including ferrihydrite and magnetite play essential roles in contaminant transport, pH control of surface and groundwater, and microbial activity. They have various applications ranging from data storage to cancer therapy. Recent studies showed that the NPs growth does not involve atom by atom nucleation but starts by...

  • Organic/Inorganic Hybrid Materials of Uranyl Peroxide Clusters and Uranium Minerals

    Creator:
    Neal, Harrison A.
    Abstract:
    Frontier research of non-aqueous actinide clusters is discussed. Since the inception of the uranyl peroxide clusters over the last decade, they have only been synthesized and characterized as solid crystals and in aqueous solution. This thesis provides thorough characterization of aqueous uranyl clusters and the first demonstration of uranyl cluster...

  • Exploring the Distinct Solution Behavior of Isostructural Polycoltanates

    Creator:
    Fullmer, Lauren
    Abstract:
    Polyoxometalates are a rapidly growing class of discrete metal oxide clusters with a wide range of applications including functional materials. These anionic clusters of the group V and VI transition metals are inexpensive and non-toxic. Within group V polyoxometalates, niobium and tantalum chemistry has been underdeveloped owing to their unique...

  • 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...

  • Polyoxoniobates: fundamental solubility trend and their application in solution and on the surface of thin films

    Creator:
    Rahman, Tasnim
    Abstract:
    Polyoxometalates (POMs) are anions consisting of three or more early transition metals ™ (Gr V and VI) oxoanions (in their highest oxidation state) linked together by a shared oxygen bond to form a 3D framework. Polyoxometalates (POMs) are a rapidly growing class of metal oxo clusters with a wide range...

  • Using Metal-Oxo Clusters to Expand Actinide Chemistry

    Creator:
    Colliard, Ian
    Abstract:
    A molecular approach to metal oxides allows to the study to fundamental bonding and formation behavior for such metals. Moreover, the molecular nature of such oxides or metal-oxo clusters allows the possibility of exploitation of the properties of the parent oxides. The tetravalent metals, in specific, (M=Zr, Hf, Ce, Th,...
