  • 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...

  • Hydrogen production via a sulfur-sulfur thermochemical water-splitting cycle

    Creator:
    AuYeung, Nicholas J.
    Abstract:
    Thermochemical water splitting cycles have been conceptualized and researched for over half a century, yet to this day none are commercially viable. The heavily studied Sulfur-Iodine cycle has been stalled in the early development stage due to a difficult HI-H₂O separation step and material compatibility issues. In an effort to...

  • Modeling and development of fabrication method for embedding membrane based microvalve in bulk microfluidic device

    Creator:
    Abhinkar, Bindiya S.
    Abstract:
    PDMS membrane-based microvalves are becoming increasingly more important for the control of fluid flow within MECS applications such as microreactors used to synthesize nanoparticles and biological macromolecules. The motivation for pursuing PDMS membrane-based microvalves is for implementing a plug flow microreactor to simulate slug flow yielding a narrower residence time...

  • Detailed analysis of the hydrogen sulfide production step in a sulfur-sulfur thermochemical water splitting cycle

    Creator:
    Caple, Kevin R.
    Abstract:
    The production of hydrogen has been one of the most heavily studied, energy related fields over the past half century, yet few methods are commercially or economically viable and none are currently sustainable. Of those aiming at the sustainable production of hydrogen using renewable resources, perhaps the most widely studied...

  • Continuous Flow Microwave-Assisted Synthesis as a Potentially Scalable Nanomanufacturing Approach

    Creator:
    Albuquerque, Gustavo Henrique T. C. de
    Abstract:
    The development of nanomaterials and the potential enhancement of their chemical, mechanical, electrical, and optical properties have led to the investigation of methods for their synthesis at lower cost with enhanced performance for next generation devices. Along with the pursuit of new materials that exhibit properties of interest, industry requires...

  • Functional materials for advanced energy and electronic devices

    Creator:
    Flynn, Brendan T.
    Abstract:
    Advances in energy technologies and electronics have typically occurred through either heightened performance or cost reduction. This dissertation explores both routes through a series of fundamental material studies that may contribute to the enabling of next generation devices. Solution based syntheses and deposition of chemical products offer a low cost...

  • Controlling the Co-Precipitation of Colloidal PbSe Quantum Dots and Their Device Performance in a Diode Architecture

    Creator:
    McCrea, Tyler D.
    Abstract:
    In this work, colloidal PbSe quantum dots (QDs) are shown to be synthesized in a controlled manner by changing the growth time and reaction temperature in a microwave synthesis method. It is explained why quantum dots make such a unique material to create electronic devices and the specific benefits that...

  • Quantum dot plasmon coupling : Fundamental study and applications

    Creator:
    Kannegulla, Akash
    Abstract:
    The dissertation focuses on the engineering of light-matter interaction using plasmonic nanoparticles and metamaterials to achieve enhanced luminescence and based on which to improve the performance of biosensing and light-emitting technologies. We designed and fabricated a spectrum of nanostructures to exhibit particular dispersion relations capable of controlling the spontaneous emission...

  • 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...

    Abstract:
    In the second chapter, a foam-core meniscus coating process was developed for retrofitting 100 nm-scale sol-gel anti-reflective coatings onto in-field solar panels through the deposition, evaporation, and curing of wet films.Advantages of this technique include the means to control fluid flow relative to substrate motion and the ability to conform...
