Hollow Nickel-Iron Nanoshells As Electrocatalysts For The Oxygen Evolution Reaction, Jonathan Batey

Chemistry & Biochemistry Undergraduate Honors Theses

The development of highly active and affordable catalysts for the oxygen evolution reaction is crucial to achieve a future where hydrogen is generated cleanly using renewable methods. Ni-Fe nanocatalysts show great promise in this area, as they are affordable and highly active. However, to overcome the industrial dominance of steam methane reforming, their activity needs improvement. This work aims to increase the activity of Ni-Fe nanocatalysts by making hollow nanostructures. Hollow Ni-Fe nanostructures were synthesized by coating a Cu template with Ni and Fe, followed by the etching of the Cu template. This left hollow Ni-Fe nanoshells, which were used …

That Song Sounds Familiar: An Analysis Of U.S. Copyright Considerations In Popular Music, Jessica Johnson

Honors Theses

Much of popular music has started to bear resemblance to songs of the past as artists rely on techniques, including sampling and interpolations, to ensure their song is a guaranteed hit. But what are the legal implications behind that, and is the line between inspiration and copying getting blurred? This thesis aims to consider the precedent of copyright law as applied to modern musical works and how the landscape of popular music has evolved over time to raise more copyright concerns. It also looks at two modern case studies of musical inspiration that have resulted in legal claims: the song …

Two Genres, One Narrative? A Critical Discourse Analysis Of Gendered Relationships In Top Hip-Hop/R&B And Country Songs (2015-2025), Alyssa A. Yarbro

Honors Theses

For this research, I examined how gendered relationships are depicted in the lyrics of 55 top-charting Hip-Hop/R&B and Country songs from the past decade (2015-2025). I employed Norman Fairclough’s Critical Discourse Analysis to examine how song lyrics use language to reproduce or challenge dominant ideas of gendered relationships. My analysis identified three prominent themes within the lyrics: Respect, Commodification, and Regret. Songs within the Respect category were characterized by these of romance, affection, and non-sexual intimacy. The commodification category included songs that had dominant themes of objectification, sexualization, and depicting individuals as disposable or interchangeable goods. The songs in the …

Cationic Polymer-Grafted Magnetic Nanoparticles For Enhanced Removal Of Anionic Dyes From Wastewater, Joia A. Traver

Chemical Engineering Undergraduate Honors Theses

Water scarcity and pollution are escalating global challenges, with textile industry wastewater often enriched with toxic dyes posing significant risks to environmental and human health. These contaminants increase turbidity, reduce dissolved oxygen levels, and ultimately impair aquatic ecosystems. This thesis focuses on the remediation of dye-contaminated water using nanoscale polymeric adsorbents. Methyl orange, a common anionic dye widely used in textile and leather industries, was selected as the model contaminant due to its terminal sulfonate group, which enables strong electrostatic and hydrogen-bonding interactions with cationic functional materials.

In this work, magnetic nanoparticles grafted with cationic polymers were synthesized and evaluated …

Demonstration Of The Relationship Between Irwin Spire Quantity And Boundary Layer Depth In The Chemical Hazards Research Center Wind Tunnel, Jace D. Beckwith

Chemical Engineering Undergraduate Honors Theses

Atmospheric Dispersion Models (ADMs) are computer-based simulations used to model gas releases for enforcing regulatory compliance, designing facilities, and responding to emergencies. Because ADMs rely on complex mathematical models, they require experimental validation to ensure accuracy. Wind tunnels offer a controlled, repeatable method for gathering validation data. The Chemical Hazards Research Center (CHRC) at the University of Arkansas operates an ultra-low speed wind tunnel for this purpose. A key feature of this tunnel is its simulated Atmospheric Boundary Layer (ABL). The simulated ABL is a turbulent layer in which wind speed increases logarithmically with height from near zero at the …

Sumset Lower Bounds In Abelian Groups, Van T. Huynh

Honors Theses

This thesis investigates sumset lower bounds across discrete and continuous settings. We begin with general inequalities in torsion-free abelian groups and then specialize to the integers modulo prime p, where we present the Cauchy–Davenport Theorem, which establishes the bound ∣A+B∣≥min(p,∣A∣+∣B∣−1). The equality case is further examined via Vosper's Theorem, which characterizes subsets attaining this bound as arithmetic progressions under suitable conditions. The continuous analogue in Euclidean spaces is then considered, where cardinality is replaced by Lebesgue measure. In this setting, the Brunn–Minkowski Inequality provides a sharp lower bound for the Lebesgue measure of A+B and serves as a geometric counterpart …

Spatial And Temporal Patterns Of Bike-Share Use In A Small City: A Case Study Of Fort Smith, Arkansas, Brianna L. Buenger

Civil Engineering Undergraduate Honors Theses

Many small and mid-sized cities in the United States face ongoing transportation challenges due to limited public transit options. This can prevent residents from being able to reach essential destinations. While bikeshare systems have been widely studied in large metropolitan areas, there is limited understanding of how usage patterns vary across space, time, and trip characteristics in small-city contexts. This study addresses this gap by examining spatial and temporal patterns of bikeshare use in a small U.S. city through a case study of the Fort Smith, Arkansas, SMILIES bikeshare program. Using approximately 10,000 trips over three years, the analysis examines …

Of The Land And Sea: A Critical Ecocultural Analysis Of Disney's Frozen And Moana, Maggie A. Andress

Communication Undergraduate Honors Theses

Within the modern era of performative inclusivity and widespread greenwashing, it is critical to examine popular media through an ecocultural lens to determine if said media is being handled responsibly as a social practice and if a discursive atmosphere is being created. This paper takes an ecocultural critical analysis of Disney’s worlds of Frozen and Moana, inspecting their treatment of the human, treatment of the more-than-human, and human/more-than-human relationships. This study finds that although both franchises have been broadly praised for cultural representation of Indigenous people groups, Disney’s failure to effectively acknowledge the intrinsic relationship between humankind and the …

This study investigates the ability of numerical simulations to predict vessel motion responses under asymmetrical loading conditions. A raked barge model was designed, constructed, and tested in a towing tank to evaluate the response amplitude operators (RAOs) for heave, roll, and pitch under various wave conditions. The model included six internal compartments that allowed different flooding scenarios to be simulated in order to create asymmetric loading conditions. Experimental testing was conducted under head seas (0 degrees) and beam seas (90 degrees) with multiple wave periods.

A numerical model of the vessel was developed using GHS to generate predicted RAOs for …

Experimentation To Study Ship Motions Under Asymmetrical Conditions, Elise Simon

Senior Honors Theses

The pioneers of ship motion analysis often used the symmetry assumption to reduce computation time and complexity. For the symmetry assumption to be valid, a ship must be upright with no heel angle, which is rarely the case. An increased interest in damaged ships has motivated further analysis of ship motions in the asymmetric condition; however, only a limited number of physical experiments have been conducted in towing tanks. This paper presents an experiment carried out to analyze vessel motions in the asymmetric condition for a box barge model. The method includes model construction, experiment setup, the test matrix, and …

Temporality Waters: Connecting People To The Brays Bayou Through Memory, Culture, And Identity Experiences In Houston, Texas, Khulda Aamir Obaid

Landscape Architecture Theses

Communities across Texas face increasing hydrological pressures from natural climate variability, changing precipitation patterns, and rapid urban growth. Although directly attributing extreme precipitation events to anthropogenic climate change is complicated by internal variability and observational limitations (de Vries et al., 2023; Griffin et al., 2024; IPCC, 2021; National Academies, 2016), cities such as Houston are preparing for more frequent and intense storms. Historical floods—including Tropical Storm Allison, the Memorial Day and Tax Day floods, and Hurricane Harvey—have exposed the limits of Houston’s predominantly hard-infrastructure flood management. The Brays Bayou watershed, particularly the Meyerland neighborhood, shows heightened vulnerability, where impervious surfaces, …

Grit, Nikita Nenashev

All Graduate Reports and Creative Projects, Fall 2023 to Present

Grit is the pursuit of intuition and sustained attention in the search for expression. My work aims to create a sense of both familiarity and mystery by operating between the framework of utility and abstraction. I investigate the liminal space between what is known and unknown, creating surfaces and forms that challenge our perceptions of beauty.

Working gesturally and swiftly invites the clay to reveal indicators of its character, leaving evidence of the forces involved in the creation of each form. Textured and scorched surfaces, produced through the firing process, reflect the transformation of malleable material into a state of …

Application Of Path Analysis To Determine The Impact Of Age And Sex On The Neural Circuits That Promote Nicotine Withdrawal Severity, Veronika Espinoza

Open Access Theses & Dissertations

The rising prevalence of electronic cigarette (e-cigarette) use presents a major public health concern, particularly in adolescent females who are most susceptible to nicotine use and its long-term negative health consequences. The goal of this dissertation was to utilize preclinical rodent models to understand how group differences in age and sex influence neural activation patterns in brain circuits believed to promote nicotine withdrawal. Prior pre-clinical work, conducted largely in male rodents, has established that there are two major brain pathways that modulate the behavioral effects of nicotine withdrawal. These include the mesolimbic and medial habenula-interpeduncular nucleus (MHb-IPN) pathways. To assess …

Provenance Analysis Of Advanced Persistent Threats In Operational Technology Environments, Laura Aminta Guevara

Open Access Theses & Dissertations

Live vulnerability testing and penetration assessments of critical infrastructure are costly, complex operationally and, in many cases, unsafe to conduct directly against live systems, whether these are commissioned in-house and through third-party providers. For Operational Technology environments specifically, these constraints are further aggravated by the limited vendor support and inconsistent security patching available that characterize many industrial communication protocols. This significantly restricts the scope and feasibility of conventional penetration testing. At the same time, the increasing overlapping of OT systems with enterprise networks and the internet has expanded the attack surface of ICS infrastructure, making more pressing the need for …
