  • Designing Dielectric Materials through Complex Metal Oxides

    Creator:
    Nikkel, Jason W.
    Abstract:
    This dissertation demonstrated that the electrical properties of complex oxide-based perovskite materials could be controlled through the careful modification of both material composition and structure. This was first shown through the modification of lead zirconate titanate (Pb(Zr0.52Ti0.48)O3, PZT) solid solutions with bismuth indate (BiInO3, BI) where the relative stability of...

  • Nutrient Addition Strategies for the Marine Diatom Cyclotella sp to Control Cell, Lipid, and Chitin Formation.

    Creator:
    Chiriboga Novillo, Omar Guillermo
    Abstract:
    Marine diatoms are unicellular photosynthetic organisms that produce unique nanomaterials, energy dense lipid-molecules, and specialty carbohydrate molecules that can be all extracted from a single microorganism. The centric marine diatom Cyclotella sp. was used as a model organism for cultivation in a biorefinery system, where multiple co-products can be harvested...

  • Probing Aqueous Ion-Pairing and Speciation of Group V Polyoxometalates

    Creator:
    Sures, Dylan J.
    Abstract:
    Polyoxometalates are discrete anionic oxo clusters of the Group V and VI transition metals that can be conceptualized as molecular metal oxides. Because they are pairable with any alkali cation, a great deal of fundamental chemistry can be gleaned from their study, including solubility trends and insight into cation binding...

  • Electron diffraction of molecules in superfluid helium droplets

    Creator:
    He, Yunteng
    Abstract:
    In this dissertation, I describe the experimental investigation in electron diffraction of molecules in superfluid helium droplets. The project is part of an overall scheme called ‘single molecule serial electron diffraction imaging’ (SS-EDI), with the ultimate goal of building an apparatus to determine atomic structures from oriented macromolecules. In SS-EDI,...

  • Power-Efficient Design Techniques and Architectures for Scalable Submicron Analog Circuits

    Creator:
    Xu, Yang
    Abstract:
    As the CMOS process scales down to submicron, digital circuit performance improves, while reduced supply voltage and lower transistor intrinsic gain make it difficult to implement analog circuits in a power efficient manner. Therefore, it has become advantageous to shift more analog signal processing functions conventionally realized in voltage (analog)...

  • Compressive Sensing for Low Power Sensor Design

    Creator:
    Behravan, Vahid
    Abstract:
    Recent sensor System-on-Chips (SoC) have enabled significant advances in energy-efficiency by incorporating various micro-powered building blocks. Unfortunately, most of these sensor systems do not address the high power cost associated with data storage and transmission, which in some cases vastly exceeds the power consumed by the rest of the SoC....

  • Exploring the Distinct Solution Behavior of Isostructural Polycoltanates

    Creator:
    Fullmer, Lauren
    Abstract:
    Polyoxometalates are a rapidly growing class of discrete metal oxide clusters with a wide range of applications including functional materials. These anionic clusters of the group V and VI transition metals are inexpensive and non-toxic. Within group V polyoxometalates, niobium and tantalum chemistry has been underdeveloped owing to their unique...

  • Defect Mechanisms in Bismuth-based Perovskites

    Creator:
    Kumar, Nitish
    Abstract:
    The aim of this research is to develop a fundamental understanding of the dominant defect species and the relevant defect equilibrium conditions for bismuth-containing perovskites to help guide the development of these materials for emerging applications. This is of paramount importance for many demanding applications, because ultimately the defect equilibria...

  • Examining Discrimination, HIV/AIDS Conspiracy Beliefs, and Condom Use Among a Diverse Sample of Young Adults

    Creator:
    Dowhower, Daniel P.
    Abstract:
    Racial/ethnic discrimination and HIV/AIDS conspiracy beliefs may contribute to disparities in use and satisfaction with healthcare services and engaging in safer sex practices. Previous studies that examined racial/ethnic discrimination and HIV/AIDS conspiracy beliefs focused primarily on African Americans with few studies focusing on Latinos. This study used longitudinal data from...

  • New Tools for Managing Erysiphe necator: Rapid Sampling Approaches and an Exploration of Grower Opinions and Perspectives towards Collective Action and Information Transfer

    Creator:
    Lowder, Sarah R.
    Abstract:
    The scale of pest and disease dispersal is often larger than the scale of individual farms. Therefore, an individual grower’s response to pests and diseases can affect and is affected by their surrounding growing region. Individual growers are also not isolated, and engage in various forms of information gathering, sharing,...
