Acoustic Response Of The Cnt-Reinforced Multilayered Acoustic Foam Composites (Mafc), Trey Brauch

Electronic Theses and Dissertations 2020 - Present

Acoustic metamaterials are engineered materials designed to control and manipulate sound propagation. Many such systems incorporate acoustic foams due to their porous structure, low density, and high specific surface area, which promotes efficient sound absorption. However, a major limitation of conventional acoustic foams -particularly open-cell varieties- is their lack of waterproofing, rendering them unsuitable for underwater or moisture-prone environments. To address this limitation, a multilayered acoustic foam composite (MAFC) was developed as a lightweight, waterproof structure with enhanced sound absorption performance. The MAFC consists of five layers: the first and fifth layers are aluminum foam, providing structural integrity; the second …

Evaluating The Impact Of K135t Mutation On Malate Dehydrogenase Kinetic Activity, Emily Frost, Kaitlyn Mello

Undergraduate Research Symposium (2026- )

Malate Dehydrogenase (MDH) is a key protein in the citric acid cycle; its dysregulation can have catastrophic impacts, such as neurological and metabolic disorders, and various cancers. MDH catalyzes the reversible oxidation-reduction reaction between malate and oxaloacetate, also reducing NAD+ to NADH in the process. The citric acid cycle is one of the central metabolic pathways, connecting to other essential pathways, such as amino acid and fatty acid biosynthesis, highlighting the importance of understanding how MDH works. A key site in MDH is the flexible loop region (amino acids 119-137), responsible for substrate binding, catalysis, and orientation. The flexibility of …

Czts Nanoparticles As Cost Efficient Catalysts For Producing Green Hydrogen, Aidan Hau

Undergraduate Research Symposium (2026- )

Hydrogen gas is produced to be used as feedstock, fertilizer, and fuel. Traditional hydrogen production produces “gray hydrogen” in a process that uses and releases fossil fuels into the atmosphere. One way to produce “green” hydrogen is with renewable energy technologies that produce hydrogen gas using electrolysis without emitting fossil fuels. In electrolysis, the hydrogen atoms bonded to oxygen in a water molecule are split to produce hydrogen. A typical catalyst for this process would be a precious metal like palladium, which can be costly. In order to make green hydrogen production more affordable, an alternative catalyst composed of CZTS …

Land Epistemic Ethic: Exploring The Complex Intersection Of Human Bodies, Land, And Identity In Middle Belt Nigeria Cosmologies, Fwangmun Oscar Danladi

International Journal on Responsibility

The Indigenous cosmologies of Nigeria’s Middle Belt emphasize the relationship between human bodies and the land, transcending Western epistemological binaries and revealing profound socio-religious insights into environmental responsibility. Practices such as the burial of newborns’ umbilical cords, often dismissed as animistic or fetishistic, embody a sacred connection to the land that emphasizes belonging rather than ownership. Using an autoethnographic approach, this study critically examines these cosmologies and identifies how the sacredness of land can serve as a repository of communal memory and potential. By reframing land not as a possession but as a relational entity, this research challenges dominant narratives …

A Black Feminist Perspective On The Role Of Community Engaged Pedagogy In Communication Education, Katrina Marie Overby, Nickesia S. Gordon

Feminist Pedagogy

As two Black feminist communication scholars, we reflect on the importance of intersectional and culturally responsive community engaged pedagogical practices in communication education. In this paper, we articulate the ways in which integrating community engaged pedagogical practices more intentionally in our curriculum, positions communication educators to participate in and contribute to advocacy based teaching that centralizes reflexivity, dialogue, critical literacy, and alliance building. Rooted in bell hooks’ theory of engaged pedagogy, our approach advocates for educators to articulate a pedagogy of Conscientizacao and to create curricula that teach us all to transgress.
