  • Pressure sensitive adhesives based on oleic acid

    Creator:
    Wu, Yili
    Abstract:
    Existing pressure sensitive adhesives (PSAs) are mostly based on petrochemicals. In this study, a novel PSA based on a renewable material, methyl oleate, was prepared and characterized. Methyl oleate was first epoxidized to form epoxidized methyl oleate that was subsequently hydrolyzed and acidified to form epoxidized oleic acid (EOA) which...

  • Investigation of Styrene-Free Unsaturated Polyester Resins for Fiber-Reinforced Composites

    Creator:
    Wu, Yili
    Abstract:
    Most of existing commercial unsaturated polyester (UPE) resins are typically composed of a UPE and a high amount of highly volatile, flammable, and toxic styrene. The emission of hazardous styrene in the handling of the UPE resins and the preparation and use of fiber-reinforced UPE composites poses severe hazards to...

  • Classifying the toxicity of pesticides to honey bees via support vector machines with random walk graph kernels

    Creator:
    Yang, Ping
    Abstract:
    Pesticides benefit agriculture by increasing crop yield, quality, and security. However, pesticides may inadvertently harm bees, which are valuable as pollinators. Thus, candidate pesticides in development pipelines must be assessed for toxicity to bees. Leveraging a data set of 382 molecules with toxicity labels from honey bee exposure experiments, we...

  • Investigation of MoS2 with Ambient Pressure X-ray Photoelectron Spectroscopy

    Creator:
    Dardzinski, Derek P.
    Abstract:
    Molybdenum disulfide (MoS2) has potential applications as a low-cost catalyst for the hydrogen evolution reaction (HER). Defects on MoS2, such as edge sites and sulfur vacancies, are known to be the major active sites for HER. Controlling the formation of these defects allows for the enhancement in reactivity of MoS2...

  • Surface Modifications for Greater Cycle Life and Energy Density in Lithium-Ion Batteries

    Creator:
    Holstun, Tucker M.
    Abstract:
    Significant challenges remain before lithium-ion batteries can support the decarbonization of the transportation and power sectors required to avert catastrophic climate change. The energy density of these batteries must be increased, while decreasing the price, and maintaining or increasing their lifespan. To improve the practical energy density of existing materials,...

  • Synthesis, surface treatment, and characterization of copper indium sulfide quantum dots

    Creator:
    Alemu, Yagenetfere A.
    Abstract:
    The need for less toxic quantum dots (QDs) has led to a significant number of investigations related to copper indium sulfide (CIS) QDs. Lower toxicity and broad band absorbance width makes CIS QDs appealing for light emitting diodes (LEDs), lasers, sensors, bio-imaging, solar cells, and computing. The optical and electronic...

  • 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...

  • 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...

  • Synthesis and evaluation of PEO-coated materials for microchannel-based hemodialysis

    Creator:
    Heintz, Keely
    Abstract:
    The marked increase in surface-to-volume ratio associated with microscale devices for hemodialysis leads to problems with hemocompatibility and blood flow distribution that are more challenging to manage than those encountered at the conventional scale. In this work, stable surface modifications with pendant polyethylene oxide (PEO) chains were produced on polycarbonate...
