  • Micro total analysis system for in-situ and autonomous spectrophotometric monitoring of iron in groundwater

    Creator:
    Koch, Corey R.
    Abstract:
    We have developed a compact micro total analysis system (μTAS) to serve as a platform for in-situ spectrophotometric water quality monitoring. Individual fluidic, optical, and electrical components were designed, developed, and characterized. These components were combined in both an integrated (single lithographic “chip-based” platform) and a modular manner. The microfluidic...

  • Design Principles of Transition Metal X-ide Catalysts for Electrochemical Oxygen Reduction and Evolution Reactions: In-Situ X-ray Spectroscopy Studies

    Creator:
    Wang, Maoyu
    Abstract:
    Hydrogen is the green fuel that can be produced from water through electrolysis and used via hydrogen fuel cells to generate electricity with zero carbon dioxide emission. The commercialization of electrolyzers and fuel cells is the critical step to achieving global carbon neutrality. However, it is severely hampered by the...

  • Characterization of CoGe Thin Films and Powders

    Creator:
    Pfau, Andrew James
    Abstract:
    Cobalt germanides have been widely studied as semiconductor contact materials, but recent theoretical studies suggest that they may also be excellent catalysts for methane steam reforming with stabilities and activities comparable to noble metal catalysts. In order to study the catalytic activity of cobalt germanides, it is critical to first...

  • Analyzing the Kinetics and Thermodynamics of Surface Reactions using Density Functional Theory

    Creator:
    Sprowl, Lynza H.
    Abstract:
    The interactions of chemical species with a solid surface play a role in many everyday applications such as heterogeneous catalysis, corrosion, and degradation reactions. Understanding the reaction kinetics and thermodynamics via rate constants and equilibrium constants, which require knowledge of the adsorbed species’ entropy, is essential for tuning these surface...

  • 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...

  • Developing rapid in vivo assays to investigate structure response relationships

    Creator:
    Truong, Lisa
    Abstract:
    Incorporation of nanoparticles (NPs) into consumer products is on the rise and human exposure to NPs is unavoidable. Currently, there is insufficient data to assess the safety of nanoparticles. I conducted a series of five studies using the zebrafish model to determine which NP components (i.e., core material or surface...

  • Zero kinetic energy photoelectron spectroscopy of polycyclic aromatic hydrocarbons

    Creator:
    Zhang, Jie
    Abstract:
    In this dissertation, I present electronic spectra of a few polycyclic aromatic hydrocarbons (PAHs): tetracene, pentacene, pyrene, benzo[g,h,i]perylene and benzo[a]pyrene using resonantly enhanced multiphoton ionization (REMPI) and zero kinetic energy (ZEKE) photoelectron spectroscopy. The work of tetracene and pentacene also combine a laser desorption source with a ZEKE spectrometer, demonstrating...

    Abstract:
    Further enhancement of energy generation is desired for practical application of anaerobic microbial systems such as microbial fuel cells (MFC) and anaerobic digesters (AD). A possible approach is to enhance the ability of microbial communities to transfer electron extracellularly in the form of electrical current. Critical to perform direct extracellular...
