  • Monolithic sorbents for microscale separations

    Creator:
    Doneanu, Angela
    Abstract:
    Over the last decade, the miniaturization of analytical systems has become an increasingly important and interesting research area. Miniaturized systems offer many advantages, including reduced reagent and sample consumption, shorter analysis times, portability and disposability. This dissertation describes novel approaches in this direction, focusing on two areas: the miniaturization of...

  • Aging and performance evaluation of marine antifouling coatings

    Creator:
    Bunn, Malachi D.
    Abstract:
    Marine biofouling is a major problem in many industries. Shipping has been afflicted with reduced vessel speed and hindered maneuverability due to organisms attaching since the dawn of sailing. To date, the primary method developed to prevent fouling is the application of biocide laden coatings with various release mechanisms. Mass...

  • Transient electric birefringence for the characterization of cellulose nanocrystals and tobacco mosaic virus

    Creator:
    Taylor, Melissa J.
    Abstract:
    The development of a transient electric birefringence (TEB) apparatus for macroparticle characterization is herein discussed. The experimental difficulties encountered were related largely to poor data resolution. Misalignment and strain birefringence in optical components further complicated results. Improved data digitization methods were developed, and precise mathematical models were derived in order...

  • Degradation of graphite electrodes in acidic bromine electrolytes

    Creator:
    Bistrika, Alexander A.
    Abstract:
    As the world's power needs grow, the demand for power from renewable resources, such as wind or solar is increasing. One major drawback associated with these renewable resources is that the power output is dependent on environmental factors, such as cloud cover and wind speeds. This allows the possibility of...

  • Cation Substitution Effects in Complex Transition Metal Oxides

    Creator:
    Duell, Brett A.
    Abstract:
    Understanding structural evolution in solids as composition changes is essential to materials properties prediction. Such structure-properties relationships are the theme of solid state chemistry. Materials scientists and chemists have utilized an abundance of simple crystal structures to enhance understanding of chemical and structural origins of properties in materials for decades....

  • Direct patterning of solution deposited metal oxides

    Creator:
    Stowers, Jason K.
    Abstract:
    Patterning of metal oxides typically involves a multi step process, involving depositing a resist, patterning that resist with some form of lithography, etching the oxide through the resist, and finally removing. This process can be simplified if the resist is removed and replaced with a metal oxide that can be...

  • Investigations of two chemical systems relevant to pyroprocessing used nuclear fuel

    Creator:
    Hames, Amber
    Abstract:
    Pyroprocessing is an advanced technology for recycling used nuclear fuel. Pyrochemical processes encompass a wide range of chemical, physical, and electrochemical methods to partition fission products and other components from used nuclear fuel, which allows for the reuse of the actinides in nuclear fuel. This dissertation investigates two chemical systems...

    Creator:
    Rodríguez Pérez, Ismael A.
    Abstract:
    Widespread installation of renewable energy sources, such as wind and solar, has been delayed by the lack of suitable stationary energy storage solutions. Current large-scale technologies, such as pumped hydro and compressed air, are geographically restricted. This is where electrochemical energy storage - batteries or hybrid capacitors can play a...

    Abstract:
    Solid state inorganic oxides play an important role in next generation electronics based on their stability, versatility, and enhanced properties over other materials. However, in order to design or tune these materials for a desired functionality it is necessary to fully understand the structure behind the properties exhibited. This dissertation...
