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 …

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 …

Reimagining The Cadenza: Bluegrass And Mozart, Linna Zheng

Honors Theses

The bluegrass-inspired cadenza for the first movement of Mozart’s Violin Concerto No. 5 is a parallel with the “Turkish” episode of Mozart’s composition. While introducing the bluegrass idiom into a Classical concerto may not be idiosyncratic, it can be understood and seen as an extension of Mozart’s own practice and approach to stylistic disruption. This approach can be understood through the concepts of Sonata Theory, revealing the cadenza as a site of productive deformation within a normative formal framework. Along with this, Robert S. Hatten’s concept of troping further supports the idea that the interaction between Classical and bluegrass idioms …

The Artificial Artist: Considering Ai’S Impact On Image Copyright, Alyse Mandelblatt

Communication Undergraduate Honors Theses

Between The One And The Many: Considering Community And Individualism - Opening Essay, John Schmalzbauer

eJournal of Public Affairs

This issue had its genesis thirty years ago at a campus lecture, a lecture that helped launch Missouri State University’s public affairs mission. Speaking on the “moral crisis in American public life,” sociologist Robert Bellah criticized the toxic individualism of the global elite, calling for a renewed commitment to the common good. Addressing an audience of 1,700 students, faculty, and local residents, Bellah ignited a community-wide discussion that reverberated across university classrooms, Ozarks congregations, and in the pages of the Springfield News-Leader.

Bellah’s questions remain no less relevant today: How can we balance individualism with our shared commitments? How …

Changes In Opioid Prescribing Patterns In Opioid Naive Patients Can Translate To Improved Outcomes In The Opioid Non-Naive Patients With Anterior Cervical Surgery: A Michigan Spine Surgery Improvement Collaborative (Mssic) Study, Anisse Chaker, Geoff Kahn, Michael Melhem, Jian-Hui Hu, Kari Jarabek, Heegook Yeo, Bhargav Ayloo, Trevor Ruesch, Adam Junn, Jad Khalil, Kenneth Easton, Richard Easton, Doris Tang, Miguelangelo Perez-Cruet, Noojan Kazemi, Ilyas Aleem, Muwaffak Abulhak, David Nerenz, Victor Chang

Conference Presentation Abstracts

Introduction: Though often necessary for adequate analgesia after spine surgery, continued opioid use can lead to chronic dependency. The Michigan Spine Surgery Improvement Collaborative (MSSIC) has demonstrated in prior work the promise of utilizing a multi-institutional morphine milliequivalent (MME) cutoff for elective anterior cervical surgery in the opioid naıve population. However, the effect of this cutoff in patients who were already on opioids pre-operatively have not previously been studied. The goal of this study was to evaluate whether changes in prescribing patterns in the opioid naıve population would also translate to the non-naıve populations, and whether the non-naıve population would …

Effective Prediction Of Martensite Start Temperature By Hybrid Machine Learning And Ethical A.I. In Materials Science, Agniprava Banerjee

Open Access Theses & Dissertations

The martensite start temperature Ms governs heat treatment design and mechanical property development in martensitic steel alloys. Accurate prediction of Ms from chemical composition alone would accelerate alloy development, yet existing empirical equations lack accuracy for multi-component steels and purely data-driven models provide no physically principled behavior outside their training domain. This dissertation develops a hybrid machine learning-physics framework for predicting Ms in steel alloys from composition. The MAP Cambridge dataset (1,020 cleaned records, 15 alloying elements) is processed through a five-stage cleaning pipeline and a 21-feature physics augmented representation, including the Ghosh-Olson Ms thermodynamic prediction as an explicit feature. …

The Impact Of Life Coaching On Self-Efficacy In Personal Goal Setting Among Black Educators In Arkansas, Veronica Cousette Jackson

Graduate Theses and Dissertations

This quantitative study examines the relationship between life coaching and self-efficacy in personal goal setting among Black educators in Arkansas, with gender explored as a moderating variable. Self-efficacy, grounded in Bandura’s (1997) social cognitive theory, is a central determinant of motivation and goal-directed behavior, influencing persistence, effort, and adaptive strategies. Although life coaching has gained recognition as a professional developmental practice, empirical research remains limited regarding its psychological effects within educator populations and its differential impact across demographic groups (Grant, 2014; Theeboom et al., 2014). This gap is particularly significant for Black educators, who experience disproportionate workforce stress and retention …
