  • Purification of cyclotron-produced 89Zr for its use in diagnostic radiopharmaceutical labeling

    Creator:
    Knaus, Clinton W.
    Abstract:
    Production of 89Zr serves as a crucial preliminary step for exploring Zr-chelates, determining their stability constants, and advancing radiolabeling methodologies for monoclonal antibody based theranostics. 89Zr is typically produced by the irradiation of natural yttrium targets, a process extensively documented in scientific literature. Two primary methods are employed: the 89Y(p,n)89Zr...

  • 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...

  • 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...

  • 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...

  • Capturing Molecular Movies of Organic and Organometallic Systems in Solution by Ultrafast Spectroscopy

    Creator:
    Boulanger, Sean A.
    Abstract:
    Ultrafast spectroscopy can exploit the structure-function relationship of chemical- and biological-based systems. More specifically, femtosecond stimulated Raman spectroscopy (FSRS) provides ground- and excited-state vibrational information with simultaneously high spectral (spatial) and temporal resolutions. The electronic counterpart, femtosecond transient absorption (fs-TA), complements FSRS data analysis as part of a comprehensive approach...

  • Using Computational and Statistical Methods as an Aid to Study Environmentally Relevant Organic Molecules

    Creator:
    Dorn, Shelby E.
    Abstract:
    In this report, three studies are presented that utilize computations to predict transformations, identities, and properties of environmental organic molecules. Each study shows how computations can lead to models of chemical behavior. The importance of this research is rooted in the need for understanding how human behavior and health intersect...

  • Unique Structural Properties and Motifs of Metal-Oxides from Solids to Clusters

    Creator:
    Malmberg, Christopher E.
    Abstract:
    In this dissertation, the structural properties, thermodynamics and defect behavior of amorphous metal oxides and polyoxometalates are studied. Amorphous metal oxides have many applications, most notably as a semiconducting material used as the active matrix of thin film transistors. Alas, the amorphous nature of these materials makes studying them rather...

  • Chemistry of High-Resolution Organotin Patterning Materials

    Creator:
    Kenane, Nizan
    Abstract:
    Organotin clusters have attracted notable attention for use as inorganic photoresists. This dissertation discerns dimeric and dodecameric organotin clusters, [(n-C₄H₉Sn)(OH)(H₂O)Cl₂]₂ (Sn₂) and [(n-C₄H₉Sn)₁₂O₁₄ (OH)₆ ]+ (Sn₁₂), both of which are stable hydrolysis and condensation products of n-C₄H₉SnCl₃. This work identifies Sn₂ as a superior precursor choice for solution deposition of...

  • Precursor-directed Biosynthesis and Total Synthesis of Aniline-containing Natural Products from the Endophytic Fungus Chalara sp. 6661

    Creator:
    Khoshbakht, Mahsa
    Abstract:
    Chalaniline A, an unusual xanthone-like aminofulvene with modest cytotoxicity, and chalaniline B [1-anilino-2,8-dihydroxy-3-(hydroxymethyl)xanthone], an antibacterial aminoxanthone, were previously isolated by Loesgen and coworkers from vorinostat-treated Chalara sp. 6661. Of note, the anilino moiety found within both chalaniline structures originates from biotransformation of the HDAC inhibitor vorinostat (SAHA, suberanilohydroxamic acid) by...
