  • CO₂ capture from wet flue gas using a water-stable and cost-effective metal-organic framework

    Creator:
    Loughran, Ryan P.
    Abstract:
    We report the use of MIL-120 as a water-stable and cost-effective metal-organic framework (MOF) for selectively capturing CO₂ from wet flue gas. Synthesized using inexpensive and environmentally benign reagents in water, MIL-120 possesses one-dimensional pores decorated with hydroxyl-bridged Al(III) ions and benzene rings with an interstitial spacing of 4.78 Å....

  • Development of Carbenoid Eliminative Cross-coupling for the Stereocontrolled Synthesis of Trisubstituted Alkenyl Moieties Within Styrenes and 1,3-Dienes

    Creator:
    Tanpure, Subhash D.
    Abstract:
    Traditional approaches for the direct preparation of alkenes are unable to fully control either the stereochemical configuration of the carbon-carbon double bond or else the regiochemistry of the substituents surrounding it. The recently introduced concept of carbenoid eliminative cross-coupling (CEXC) offers a remedy to these deficiencies by providing for a...

  • The Local Structure of Functional Electroceramics

    Creator:
    Culbertson, Charles M.
    Abstract:
    This work investigates the relationship between the local structure and physical properties of a set of classical (MgTiO3, CaTiO3, SrTiO3, and BaTiO3) and complex ((1-x)Ba(Zr0.2Ti0.8)O3-x(Ba0.7Ca0.3)TiO3[BZT-BCT], Na0.5Bi0.5TiO3 [NBT]) perovskite electroceramics. The materials in this work were synthesized via standard solid state ceramic synthesis, the structure was investigated through a number of...

  • 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,...

  • Total Synthesis of Aspidosperma Alkaloids Leuconoxine, Melodinine E and Mersicarpine and Synthetic Studies directed toward the Iboga Alkaloid Ibogaine: Progress directed toward the dimeric Cephalotaxus Alkaloid Cephalancetine C

    Creator:
    Kim, GilSoo
    Abstract:
    The first part of this manuscript is about the total synthesis of the aspidosperma alkaloids leuconoxine, melodinine E and mersicarpine. Our synthetic strategy used a radical translocation-conjugate addition cascade to construct the core of the natural product. Specifically, a vinyl radical was generated from the homolysis of the C–I bond...

  • Gene Expression, Structure Elucidation, and Bioactivity of Aspergillus Natural Products

    Creator:
    Neuhaus, George F.
    Abstract:
    The study of natural products (NPs) and their application has shaped humanity. Starting with the idea of using plants as medicine, it has now grown into the science of purifying and identifying organic molecules from nature to study their inherent biological activities. Understanding the molecular structures of NPs is the...

  • 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...

  • Insights and Patterns from Quantitative and Statistical Analyses of Chemical Systems

    Creator:
    Grove, Markas Albert
    Abstract:
    The work presented here is the culmination of efforts in describing complex chemical systems with statistical methods, thereby providing relatively simple quantitative models and easily comprehensible qualitative insights. The following investigations have various goals, such as development of new methods, fundamental understanding, molecular control of chemical species, and advancement of...

    Bahro, Christopher
    Abstract:
    The general theme of this dissertation is the development of new analytical sensors to quantitatively study biological and environmental samples in aqueous and non-aqueous environments. A platinum ultramicroelectrode (UME) and a unique carbon-based pH microprobe were used to design a new SECM-based electrochemical bioassay. The Pt UME was used to...

  • Stereocontrolled Synthesis of Allenes by Eliminative Cross-Coupling of Carbenoids

    Creator:
    Cao, Yang
    Abstract:
    The bimolecular reaction of two carbenoid species resulting in the formation of a carbon-carbon double bond (pi-system), referred to herein as carbenoid eliminative cross-coupling (CEXC), involves a series of three fundamental steps: (i) ate-complex formation (transmetalation), (ii) 1,2-metalate rearrangement, and (iii) beta-elimination. All three steps are stereospecific and so the...
