Development Of Highly Active And Stable Hybrid Cathode Catalyst For Pemfcs, Won Suk Jung

Theses and Dissertations

Polymer electrolyte membrane fuel cells (PEMFCs) are attractive power sources of the future for a variety of applications including portable electronics, stationary power, and automobile application. However, sluggish cathode kinetics, high Pt cost, and durability issues inhibit the commercialization of PEMFCs. To overcome these drawbacks, research has been focused on alloying Pt with transition metals since alloy catalysts show significantly improved catalytic properties like high activity, selectivity, and durability. However, Pt-alloy catalysts synthesized using the conventional impregnation method exhibit uneven particle size and poor particle distribution resulting in poor performance and/or durability in PEMFCs. In this dissertation, a novel catalyst …

Framing Death: Politics, Meaning, And The Strategic Communication Of Organ Donation Messages In South Carolina, Jeremy T. Vanderknyff

Comparing The Geography Of Environmental Justice Guidelines, Fish Consumption Waterbodies, And Land Use/Land Cover In South Carolina, Matthew James Neet

Theses and Dissertations

Environmental justice (EJ) grew out of the Civil Rights movement of the 1960s, as well as grass roots organizations during the 1980s and early 1990s. However, it was not until President William J. Clinton signed Executive Order (EO) 12898 in 1994 that EJ became an official governmental policy. With this directive, federal agencies made EJ part of their daily operations. EO 12898 had two overriding goals, the fair treatment and meaningful involvement of all populations. As part of these goals, minority, low-income, and native populations would be analyzed for any disproportionate and adverse impacts on human or environmental health. Despite …

Services Received And Parental Perception Of Quality Of Life For Children With Autism Spectrum Disorder, Judith Marie Cholewicki

Theses and Dissertations

With the rapid increase in the rate of children diagnosed with Autism Spectrum Disorder (ASD), there has been a surge in treatment interventions and outcome measures. Treatment interventions consist of evidence-based practices and programs that lack scientific validation. Parents’ selection of a treatment or multiple treatments is often based on the desire to maximize their child’s personal well-being (Pituch et al., 2011; Rodger, Braithwaite, & Keen, 2004). Current outcome measures provide valuable information and may demonstrate a change in a standard score. For example, a change in intelligence quotient, is not evidence that this change contributes to the child’s personal …

Beyond Ideals: Proslavery Reforms On A Nineteenth-Century Cotton Plantation, Kevin R. Fogle

Theses and Dissertations

The last four decades of the antebellum period witnessed the rise of a proslavery plantation reform movement aimed at preserving slavery in the face of increasing abolitionist pressure.

Spectroscopy And Chemometrics For Cultural Heritage And Forensics: Conservation Of Magnetic Tape By Identifying Degraded Polymer Signatures; And Characterizing The Chemiluminescent Reaction Of Luminol With Blood, Brianna Marie Cassidy

Theses and Dissertations

The first half of this manuscript focuses on the identification of degraded magnetic tape using attenuated total reflectance Fourier transform infrared spectroscopy (ATR-FTIR) and multivariate statistics. For several decades before the digital era, magnetic tape was the dominant audio and visual recording medium. A majority of magnetic tapes contain polyester urethane (PEU) binders, which are known to degrade via hydrolysis, making the retrieval of recorded data difficult and at times impossible. Degraded tapes are currently identified through visual inspection followed by playback on vintage equipment. However, if degraded tapes are played, they are likely to stick and shed onto player …

Development Of Ultra-Low Loading Of Compressive Pt Lattice Cathode Catalyst On Highly Stable Support For Pemfc Automotive Applications, Tianyuan Xie

Theses and Dissertations

The major barriers in the commercialization of the fuel cell technology for automotive applications are the cost and durability of the Pt catalyst and the support stability at high potentials.

Do Discipline Style And Parenting Self-Efficacy Interact To Predict Observed Child Behavior? Outcomes From A Representative Sample Of Mothers With Young Chilren, Emily Noel Neger

Theses and Dissertations

Both parenting style and parents’ sense of their own parenting self-efficacy (PSE) have been found to predict child behavior outcomes in young children. Parents who engage in lax or overreactive parenting practices or who lack confidence in their parenting abilities are more likely to have children who display disruptive and noncompliant behavior. Until now, very little research has examined whether an interaction exits between these two constructs in predicting child behavior outcomes. The current study looked to fill this gap and assess whether a significant moderation relationship exists between parents’ parenting style and PSE in predicting observed child behavior. A …
