  • The mobilization of heavy metals from contaminated soil using low molecular weight organic acids

    Creator:
    Kang, Sun Ki
    Abstract:
    More than 30,000 potential Superfund sites have been identified. Heavy metals are contaminants at many of these Superfund sites. The average cost of cleanup a single-typical Superfund site currently stands at $20 million, and it is expected that the cost may escalate to $50 million within the next decade. Problems...

  • Iron oxidation by Thiobacillus ferrooxidans

    Creator:
    Kang, Sun Ki
    Abstract:
    The bacterium most frequently used in microbial leaching processes and studies is Thiobacillus ferrooxidans. Applications of this bacterium include the treatment of coal, low-grade ores and industrial solid wastes for the solubilization of pyrite and other trace metals associated with sulfides. The goal of this study was the development of...

  • Human platelet adhesion to heparinized silica surfaces

    Creator:
    Bolsinger, Travis Samuel Sebastian
    Abstract:
    Heparin was modified and immobilized to surface-activated silica surfaces using two different reaction schemes. End-aminated heparin was reacted with 2-iminothiolane to produce free thiol groups at the terminal ends of the heparin chains. The end-thiolated heparin was immobilized by reaction with a pyridyl disulfide activated poly[ethylene oxide]-poly[propylene oxide]-poly[ethylene oxide] triblock...

  • Removing Chemical Oxygen Demand (COD) Assay Interference from Landfill Leachate Samples Treated with Fenton's Reagents

    Creator:
    Palmer, Matthew
    Abstract:
    Incompatibility between Fenton’s Reagents and a potassium dichromate COD test provides interference that prevent accurate measurements of the concentration of organics from oxidized samples. Several treatment options were tested to remove this interference. Oxidation of reagents was eliminated as a potential method for removal of interference due to sample contamination....

  • A (3-Aminopropyl)triethoxysilane (APTES) and Glutaraldehyde Functionalized Cellulose Surface for Immunoassays

    Creator:
    Harley, William
    Abstract:
    The detection of biomolecules is critical for clinical diagnostics but requires specialty labor and high cost. The use of microfluidic paper-based analytical devices (µPADs) for bioassays is simpler and cheaper but has low sensitivity. Improved immobilization of antibodies onto cellulose is demonstrated through surface functionalization with APTES and glutaraldehyde. The...

  • Application of Self-Assembled Monolayers to InGaZnO Thin Film Transistors

    Creator:
    Motley, Joshua R.
    Abstract:
    Investigations on the application of self-assembled monolayers (SAM) to indium gallium zinc oxide (IGZO) thin film transistors (TFT) for fabrication and channel modification are presented. The back channel of IGZO thin film transistors can be modified by the absorption of self-assembled monolayers. The electrical properties of the IGZO exposed back...

  • Down-Shifting Nanoparticles and Anti-reflective Nanoparticles Co-Coating Applied on Top Glass Cover of Silicon-Based Solar Panels

    Creator:
    Jing, Qun
    Abstract:
    Photoluminescence (PL) materials have attracted a lot of attention in last several decades. Recently PL materials, which can convert low-efficiency Ultraviolet (UV) or Infrared (IR) light to high-efficiency visible light, have been widely applied in the research of improving conversion efficiency of solar cell. As one of the most common...

  • Study of Garnet Type Electrolyte Li₇La₃Zr₂O₁₂ Structure and Electrochemical Performance

    Creator:
    Wang, Yan
    Abstract:
    Cubic phase Li₇La₃Zr₂O₁₂ (LLZO) is a promising solid electrolyte for all solid-state lithium-ion battery, due to its reasonable ionic conductivity, stable against metallic Li, wide chemical window, and thermal and chemical stability. The main aim of this thesis is to investigate the influences of different synthesis methods on the structure...

    Raman, Ramya
    Abstract:
    Sepsis is an inflammatory reaction occurring throughout the human body to infections caused by bacteria, fungi, and or other forms of pathogens. It is essential to find an alternative treatment method for sepsis, to lessen the dependence on antibiotics. Hemoperfusion is an absorbent device that removes select targets from blood,...
