  • Total synthesis of sparteine alkaloids from a common tetraoxobispidine intermediate

    Creator:
    Melbardis, John
    Abstract:
    In previous work (Blakemore et al. Org. Lett. 2005, 7, 4721; Heterocycles 2006, 70, 609), successful elaborations of the lupine alkaloids (±)-α-isosparteine (dl-2) and (±)-β-isosparteine (dl-3) were realized from a common tetraoxobispidine precursor, 3,7-diallyl -2,4,6,8-tetraoxo-3,7-diazabicyclo[3.3.1]nonane (93). Herein, the tetraoxobispidine approach to lupine alkaloids was extended to a total synthesis of...

  • Expediting the Generation and Analysis of Amorphous Oxide Computational Models: Modeling Complex Systems Swiftly

    Creator:
    Buchanan, Jacob C.
    Abstract:
    In this dissertation, the process of computational modeling of amorphous oxide materials is studied. Amorphous oxides have random atomic arrangements with no long-range structural order which makes it difficult to study structure-property relationships. Despite the difficulties, amorphous oxides have great uses as semiconductors and dielectrics in thin-film transistors. The ability...

  • DC/AC Stability of In-Ga-Zn-O Thin-Film Transistors

    Creator:
    Zhou, Fan
    Abstract:
    The electrical stability of amorphous indium-gallium-zinc oxide (a-IGZO) thinfilmtransistors (TFTs) is investigated for flat-panel display applications. Althoughproducts incorporating a-IGZO TFT backplanes are already commercially available,e.g., iMac with 5K retina display, technical challenges need to be addressed for nextgenerationapplications, e.g., active-matrix organic light-emitting diode displays.Device stability is one crucial issue. The...

  • Development of Cu-based Thin Films for Optoelectronic Applications

    Creator:
    Angelos, Gregory S.
    Abstract:
    CIGS and CdTe based commercial thin-film solar cells (TFSCs) require an absorber thickness greater than 2 µm and 4 µm, respectively, to adequately absorb the solar spectrum. To efficiently extract photoexcited electrons, these TFSCs require relatively defect-free absorbers with high-minority carrier mobility (> 100 cm2V−1s−1) and long lifetime (> 10...

  • Terahertz transmission & spectroscopy of vertically grown multi-walled carbon nanotube forests

    Creator:
    Maizy, Louis
    Abstract:
    In this thesis, I present studies in the field of terahertz [THz] spectroscopy. It covers both the generation and detection of ultra-fast broadband THz pulses, as well as the transmission properties of vertically grown multi-walled carbon nanotube forests [MWCNTs]. We have found that these vertically grown MWCNTs respond strongly to...

  • Generating and using terahertz radiation to explore carrier dynamics of semiconductor and metal nanostructures

    Creator:
    Jameson, Andrew D.
    Abstract:
    In this thesis, I present studies in the field of terahertz (THz) spectroscopy. These studies are divided into three areas: Development of a narrowband THz source, the study of carrier transport in metal thin films, and the exploration of coherent dynamics of quasi-particles in semiconductor nanostructures with both broadband and...

  • Scanning photocurrent microscopy study of photovoltaic and thermoelectric effects in individual single-walled carbon nanotubes

    Creator:
    DeBorde, Tristan
    Abstract:
    Carbon Nanotubes are a unique family of nanostructures that have shown remarkable promise for mechanical, electrical, and optical applications. Fundamentally similar to the earlier discovered Buckminsterfullerene (C₆₀), carbon nanotubes are hollow cylinders formed from a single sheet of carbon atoms. The research presented in this dissertation investigates several carbon nanotube...

  • Cis-2,5-diaminobicyclo[2.2.2]octane : a novel C₂-symmetric scaffold for asymmetric catalysis

    Creator:
    Shaw, Subrata
    Abstract:
    This thesis describes the development of a new enantioselective synthetic method employing chiral cis-2,5-diaminobicyclo[2.2.2]octane-based organometallic catalysts. The significance of this new method to organic synthesis is illustrated with preparation of enantioenriched products that are transformed to important pharmaceutical agents. Chapter 1 provides a brief historical overview of asymmetric catalysis, especially...

  • Label free biosensing with carbon nanotube transistors

    Creator:
    Leyden, Matthew R.
    Abstract:
    As electronics reach nanometer size scales, new avenues of integrating biology and electronics become available. For example, nanoscale field-effect transistors have been integrated with single neurons to detect neural activity. Researchers have also used nanoscale materials to build electronic ears and noses. Another exciting development is the use of nanoscale...

  • Conformational Consequences: Calcium Regulates the Association Between Dysferlin C2A & PI(4,5)P2

    Creator:
    Otto, Shauna C.
    Abstract:
    Dysferlin is a ∼230 kDa terminally anchored membrane protein that is ubiquitously expressed, but is particularly enriched in skeletal and cardiac muscle tissue. Mutations covering the length of the protein have been linked to muscle wasting diseases including limb-girdle muscular dystrophy and Myoshi myopathy. Dysferlin has been shown to play...
