  • Digital Fourier Holographic Microscopy and Potential Applications Towards the Design of Photodynamic Therapy of Osteosarcoma

    Creator:
    Rossi, Vincent Michele
    Abstract:
    This work entails both imaging and therapeutic applications of biomedical optics. In both contexts, an understanding of light transport in tissues is necessary. An overview of optical transport in tissues is given, including scattering theory. Digital Fourier holographic microscopy is introduced and applied as a means of metrology via optical...

  • Evaluation of Stress Corrosion Cracking of 316L Stainless Steel in FLiNaK Using the Slow Strain Rate Technique

    Creator:
    Quintana, Xavier A.
    Abstract:
    Molten salts have been targeted as a promising coolant for next generation reactors due to their high boiling point, heat capacity, and thermal conductivity. Despite these benefits, molten salt systems present unique materials compatibility issues, highlighted by the aggressive corrosion attack and dealloying typically seen on materials in these environments....

  • The particle on a ring in polymer quantum mechanics : a quantum cosmology analogue on a compact space

    Creator:
    Siebersma, Maxwell R.
    Abstract:
    Loop quantum gravity is a framework for quantizing general relativity which imposes a discrete structure on space. In exploring the structure of loop quantum gravity, researchers have investigated loop quantum cosmology, a toy model with reduced degrees of freedom while maintaining a discrete space. Polymer quantum mechanics is a framework...

  • Evaluating the response of bees to visual attractants in resource-poor environments

    Creator:
    Parvin, Lucas
    Abstract:
    Bee populations are declining around the globe, while the need for their pollination services is increasing with growing food demands by an expanding population. There is a need for innovative practices to increase pollination in agricultural environments without harming wild bee populations. However, the use of artificial visual attractants has...

  • Fabrication and optical measurement of flip-chips for noninvasive electrostatic gating of nanomaterials

    Creator:
    Nichols, Dublin MacCray
    Abstract:
    Electrostatic gating of nanomaterials allows researchers to control carrier density and shape potential barriers that confine carriers. Lithographic patterning followed by metal deposition is the standard technique to define electrostatic gates; however, the methods of fabricating these devices often involve harsh processing. For example, taking a material to high temperatures...

  • Theoretical study of beryllium borohydride Be(BH₄)₂

    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...

  • 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...

  • 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...

  • Much Ado About Weak Measurement

    Creator:
    Bauml, Benjamin Noë
    Abstract:
    I had to write again. My research lay in science, and it was a science of three parts. The first part made a careful, introductory chapter, begged for by things that were lacking. It summarizes the von Neumann measurement model, derived from the Stern-Gerlach experiment, and it explains how weak...

    Creator:
    Mousavian, Ali
    Abstract:
    This dissertation covers my work relating to the application of strong terahertz (THz) radiation to study the nonlinear properties of nano-scale material. It presents experimental and numerical studies on the optical and electronic properties of various material system including single-layer graphene, multi-walled carbon nanotubes (MWCNTs), nanoantenna-patterned gallium arsenide (GaAs) and...
