  • Characterization and Investigations of Thin-Film Materials with X-ray Photoelectron Spectroscopy

    Creator:
    Diulus, J. Trey
    Abstract:
    Surface characterization of materials is widely utilized over a range of disciplines and essential to the development of new materials, technology, or processes. Metal oxide nanoclusters have shown promise as potential new generation photoresist materials for extreme ultraviolet (EUV) nanolithography. Organotin clusters have been proposed as potential candidates for resist...

  • Deposition and characterization of thin films

    Creator:
    He, Shidong
    Abstract:
    Recent studies have indicated that nickel gallium alloys can be effective for the catalytic hydrogenation of CO2 to methanol. To simplify the characterization of NiGa catalysts, we are developing model systems using NiGa thin films. We prepared NiGa thin films by RF magnetron sputtering using an equiatomic alloy target, followed...

  • Understanding Charge and Mass Transfer Phenomena in Functional Oxide Heterostructures

    Creator:
    Samarakoon, Widitha
    Abstract:
    Oxides are a versatile class of materials with a wide range of electronic, optical, and magnetic properties. This makes them ideal for use in a multitude of functional devices for oxide electronics, electrochemical conversion, and storage. The overall performance of these devices is governed by atomic scale charge and mass...

  • Metal Oxide Cluster Chemistries for Next Generation Nanomanufacturing

    Creator:
    Frederick, Ryan T.
    Abstract:
    Metal oxide clusters are promising inorganic photoresists in next generation nanomanufacturing because of their potential for high-resolution and low line-edge roughness patterning, and exceptional sensitivity to extreme ultraviolet (EUV) radiation. In EUV patterning, absorption of EUV radiation leads to electron emission that serve as a primary species for driving radiation...

  • The effects of engineered coatings and natural organic matter on nanoparticle aggregation

    Creator:
    McDowell, Shannon A.
    Abstract:
    In order to better predict the aggregation state of nanomaterials, the factors that influence aggregation must be understood. The combined effects of natural and engineered coatings have been shown to factor into nanoparticle aggregation behavior in preliminary research. In this study, aggregation behaviors of gold nanoparticles with two different engineered...

  • Towards a Selectively Bioactive Surface for the Removal of Circulating Endotoxin in Blood

    Creator:
    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,...

  • Nonthermal Plasma Microreaction Engineering for Gas and Liquid Processing

    Creator:
    Pommerenck, Justin
    Abstract:
    Atmospheric pressure plasma is non-thermal at millimeter to micrometer separations. It represents an alternative low exergy initiator of many chemical reactions. In many instances heat, light or sound are not efficient providers of the necessary energy to overcome chemical activation barriers. The focus of this research is applying dc nonthermal...

  • Oxidation of hydrocarbon in a carbon nanotube supported corona discharge in micoreactor : oxidation of ethylene

    Creator:
    Alanazi, Yousef M.
    Abstract:
    Population growth driven sustainability issues, including the food resource issue, are pressing problems in need of attention. The goal of the present thesis is to examine the ability of an electric non-thermal plasma based microreactor to destroy ethylene, a known plant hormone responsible for losses in the range of 20%...

  • Functional polymers and proteins at interfaces

    Creator:
    Schilke, Karl F.
    Abstract:
    Functional polymers and proteins at interfaces and surfaces are of fundamental importance for biomaterials, biocatalysis and microreactor applications. Candida antarctica lipase B immobilized on poly-DL-tryptophan tethers showed 30x higher specific activity in aqueous and non-aqueous media than the same enzyme adsorbed or covalently bound directly to the surface. An excess...
