  • Utilization of Renewable Energy via Thermochemistry

    Creator:
    Lei, Fuqiong
    Abstract:
    Utilization of solar energy or wind energy for electricity production is inherently challenging due to the diurnal and seasonal variations and normal intermittency. Effective, high efficiency storage methods need to be developed for further advancing renewable energy utilization. Endothermic chemical processing and thermochemical energy storage can be both employed as...

  • Inkjet-Printed Metal Halide Semiconductors for Wearable Electronics

    Creator:
    Li, Shujie
    Abstract:
    There is an emerging interest in developing wearable electronics as a platform, which provides the flexibility of a wearable while maintaining its promising functionality as smart textiles. Metal-halide semiconductors are attractive materials with tunable optical and electrical properties. Researchers have widely studied and applied it for advanced photonics and optoelectronic...

  • Process Intensification toward Reduced Exergy Destruction in Methane Upgrading

    Creator:
    Freiberg, Lucas J.
    Abstract:
    Exergy relates to thermodynamic value or usefulness in the universe. In this dissertation, three methods in the realm of "process intensification" are explored to reduce exergy destruction by equipment and processes that are used to convert and upgrade methane. Thermodynamic efficiency of a virtual heat exchanger is improved with a...

  • Engineering an Ex-Vivo System to Study Transport Phenomena in the Human Intervertebral Disc

    Creator:
    Shalash, Ward
    Abstract:
    Back pain is the leading cause of disability worldwide, entailing a significant socioeconomic impact. A primary source of back pain can be attributed to intervertebral disc (IVD) degeneration allowing nerve ingrowth, facet joint arthritis, disc bulging, and osteophyte formations that press on nearby nerve roots or the spinal cord. While...

  • Solar-driven Dry Reforming Reaction in a Milli-scale Reactor

    Creator:
    Wang, Yige
    Abstract:
    Dry reforming of methane to syngas using CO2 was performed in a solar-driven milli-scale reactor, which converts solar energy to chemical energy. The process aims to upgrade the energy content of the feed stream using sustainable energy. The effect of mean residence time, temperature and CO2:CH4 ratio on conversion and...

  • 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...

  • Fundamental Investigations of Electrocatalysis: Mechanistic Implications of Catalyst Electronic Structure

    Creator:
    Carvalho, O. Quinn
    Abstract:
    Heterogeneous catalysis modulates the rate and selectivity of reaction processes by stabilizing a series of intermediate states on solid surfaces, facilitating the production of many commodity chemicals modern society relies upon. Conventional, thermal catalytic processes—conducted at elevated temperatures and pressures—source thermal, mechanical, and chemical potential energy from carbon-hydrogen bonds— combustion...

  • Growth, Characterizations, and Applications of Patterned Nanostructured Thin Film

    Creator:
    Gao, Zhongwei
    Abstract:
    A unique microreactor-assisted nanomaterial synthesis and printing process was studied for the fabrication of patterned metal oxide nanostructured thin films. The process uses a continuous flow microreactor to control and generate a reactive chemical flux that was transported to a patterned microfluidic channel. The microreactor-assisted nanomaterial synthesis process can generate...

  • 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...

  • Antibiotic Resistance in Septic Sludge and Receiving Environments of Ho Chi Minh City, Vietnam

    Creator:
    Schutzius, Genevieve Conyers
    Abstract:
    Approximately ninety percent of urban Vietnamese households are connected to septic tanks, from which up to three-quarters of the sludge is reported to be dumped into waterways in residential areas. Vietnam has a considerable prevalence of antibiotic misuse and resultant antibiotic-resistant bacteria (ARB) in the human microbiome. Due to the...
