  • Mode patterns in quadrupole resonator with anisotropic core

    Creator:
    Thongrattanasiri, Sukosin
    Abstract:
    This thesis deals with applications of uniaxial anisotropic crystals for microcavity resonators with partially chaotic underlying ray dynamics. We develop an implementation of the scattering matrix formalism, and relate the eigenvalues and eigenvectors of the scattering matrix to the field distribution of inside the system. Using the developed technique, we...

  • 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...

  • 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...

    Creator:
    Alghamdi, Maha D.
    Abstract:
    Ab initio calculations using the B3LYP and CCSD(T) methods were employed in this work to explore the most stable structure of the intriguing compound Be(BH₄)₂, for which as many as seven different structures have been proposed in the literature. Use of the B3LYP density functional method with several large basis...

  • Optical trapping and acoustical probing of ultrasound contrast agent microbubbles confined in capillaries

    Creator:
    Almaqwashi, Ali
    Abstract:
    In an effort to develop an optical-acoustical understanding of ultrasound contrast agent microbubble dynamics in a micro-environment that resembles blood vessels, this thesis presents experimental work on optical trapping and acoustical probing of ultrasound contrast agent microbubbles confined in regenerated cellulose capillaries. First, we showed by acoustical means that the...

  • Study of creeping, inertial and turbulent flow regimes in porous media using particle image velocimetry

    Creator:
    Patil, Vishal A.
    Abstract:
    Porous media flows are encountered in many natural and man-made systems such as gas adsorption, filtration, heat exchangers, combustion, catalytic reactors and groundwater hydrology. This study experimentally investigates these flows as function of pore Reynolds number, Re[subscript pore]. The pore Reynolds number is based on the porous bed hydraulic diameter,...

  • Ground tap placement and sizing to minimize substrate noise coupling in RF LNAs

    Creator:
    Sundaresan, Arathi
    Abstract:
    The substrate noise injected by a stepped buffer circuit into two single-ended 1.5GHz low noise amplifiers is examined for a heavily doped 0.25µm CMOS process. The difference in the LNA noise rejection is characterized as a function of the size and placement of substrate contacts. The use of a resistive...

  • 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...

  • Broadband modeling of on-chip transformers for silicon RFICs

    Creator:
    Rapolu, Kavitha
    Abstract:
    Magnetically coupled passive transformers are increasingly integrated on-chip for various analog and radio frequency (RF) applications including direct current (DC) isolation, impedance transformation/matching, and conversion between single-ended and differential signals. A primary motivation for the on-chip integration of transformers is the overall size reduction and reduced cost. However, the performance...
