  • Aryl acetylene substituent effects : the synthesis and application of biaryls

    Creator:
    Naffziger, Michael R.
    Abstract:
    The work described herein details the synthesis and application of biphenyls that probe the effects of hydrogen, Cl / Br, and methyl substituents on the aryl ring of the terminal acetylenic carbon. From this work, we successfully developed the rapid synthesis of phenyl acetylenes in 3-4 steps from inexpensive commercially...

  • Structure-Property Relationships of Disordered Electronic Materials : From Crystalline to Amorphous

    Creator:
    Surta, Todd Wesley, Jr.
    Abstract:
    Two perovskite materials (Bi0.5(A)0.5)(Sc0.5Nb0.5)O3, where A = K+ and Na+ were synthesized phase pure for the first time. Their structures were determined by indexing synchrotron X-ray diffraction data and subsequent combined Rietveld refinement on neutron and synchrotron X-ray diffraction data revealing significant disorder on the A-sites of these materials. A...

  • Aqueous niobium chemistry at low pH : new precursors for oxide thin films

    Creator:
    Park, Deok-Hie
    Abstract:
    Phosphate and peroxide stabilize new oxo-hydroxo niobium clusters in water at low pH. The clusters open a new chapter in aqueous niobium chemistry under acidic conditions. The clusters also produce atomically smooth, amorphous niobium oxide phosphate (NbPOx) thin films. Reaction pathways from cluster solutions to amorphous niobium oxide phosphate solids...

  • Synthesis and investigation of layered oxides with honeycomb ordering

    Creator:
    Schmidt, Whitney L.
    Abstract:
    Synthesis and discovery lies at the core of every field in chemistry. The investigation of the structure-property relationships in compounds known or new is the fundamental purpose of solid state chemistry. Mixing related solid state compounds to form solid solutions can lead to exciting new and/or unexpected properties. Layered compounds...

  • Gene Activation Strategies in Filamentous Fungi for Natural Products Discovery

    Creator:
    Adpressa, Donovon A.
    Abstract:
    Fungi have long been a prolific source of clinically approved drugs. The antibiotic penicillin, the cholesterol lowering statins, and the immunosuppressant cyclosporine have changed the treatment of human diseases in the last century. Recently, genome analysis of filamentous fungi has revealed that the biosynthetic potential for natural product expression is...

  • Pactamycin Inspired Drug Discovery: A Synthetic and Chemoenzymatic Approach

    Creator:
    Brumsted, Corey J.
    Abstract:
    Pactamycin, first reported in 1962, is a potent antitumor antibiotic produced by the soil bacterium Streptomyces pactum. Structurally, it contains a cyclopentitol core unit, a 3-aminoacetophenone (3AAP), a 6-methylsalicylic acid (6-MSA), and a N,N-dimethyl urea. The aminocyclopentitol ring is derived from glucose, possibly via N-acetyl glucosamine (GlcNAc), the 3-aminoacetophenone (3AAP)...

  • Refractory Amorphous Metal Thin Films

    Creator:
    Olsen, Kristopher R.
    Abstract:
    Amorphous metal thin films lack the grain boundaries and dislocations present in crystalline metal films. As a result, amorphous metal films can be more mechanically robust, atomically smooth, and more resistant to chemical attack than crystalline metals. However, amorphous metals are meta-stable and subject to crystallization upon heating, thus limiting...

    Abstract:
    Crystals of an incongruent-melting compound, Ba₃MgSi₂O₈, were grown by the flux method and its structure was determined by single crystal X-ray diffraction methods. Ba₃MgSi₂O₈ crystallizes in trigonal space group P-3[bar]m1 with a = 5.6123(3) Å, c = 7.2667(9) Å and Z = 1. Eu²⁺ ions prefer one crystallographic Ba site...
