Acoustic Response Of The Cnt-Reinforced Multilayered Acoustic Foam Composites (Mafc), Trey Brauch Apr 2026

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 …

Brain Delivery Of Antibody-Derived Biologicals For Alzheimer’S Disease: An Updated Narrative Review, Rachita K. Sumbria, Ruben J. Boado Apr 2026

Brain Delivery Of Antibody-Derived Biologicals For Alzheimer’S Disease: An Updated Narrative Review, Rachita K. Sumbria, Ruben J. Boado

Pharmacy Faculty Articles and Research

Antibodies directed against β-amyloid (Aβ) have been developed for the treatment of Alzheimer’s disease (AD). However, the in vivo central efficacy is reduced by the poor penetration of antibodies across the blood–brain barrier (BBB). In addition, these antibodies have been associated with adverse effects like amyloid-related imaging abnormalities. Thus, the development of new antibody-based therapies for AD with improved transport across the BBB may improve efficacy and reduce adverse effects. Antibodies targeting the BBB transferrin receptor (TfR) are able to cross the BBB through receptor-mediated transcytosis, producing a global distribution throughout the brain. Along the same line, bispecific antibodies directed …

Neural Responses To Acute Hypoxia And Hyperoxia, Daniel Graham, Jonathan Marsden, Alastair D. Smith, Gary Smerdon, Stephen D. Hall

School of Psychology

The brain's high metabolic demands make it highly sensitive to oxygen level changes, with both hypoxia and hyperoxia affecting cognitive and neural function. However, the underlying neural mechanisms remain unclear. This study aimed to characterise the effects of acute normobaric hypoxia and hyperoxia on neural function and perceptual thresholds using EEG, visual evoked potentials (VEPs), and critical flicker fusion (CFF) thresholds. In a single-blind, randomised, crossover design, thirty participants inhaled 10.5%, 21%, or 100% oxygen while resting-state EEG, VEPs, and CFF thresholds were recorded. Hypoxia reduced CFF thresholds in an exposure-dependent manner, while hyperoxia produced a smaller, transient reduction. Resting-state …

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 Apr 2026

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 …


An Analysis Of Katsinam Figurines In The University's Gendler Collection, Sam Rekstad Apr 2026

An Analysis Of Katsinam Figurines In The University's Gendler Collection, Sam Rekstad

Undergraduate Research Symposium (2026- )

After a cultural shift in the late nineteenth and early twentieth centuries, Euro-American collectors and ethnologists took a significant interest in sacred indigenous objects such as the Hopi Katsinam figurines, which spurred transformations in the ways the figurines tended to be stylized, as well as in how they were circulated. Such figures were initially created solely for ritual and communal purposes, but in modern and contemporary times, they are often created by makers who identify themselves as artists. In this project, I study the history surrounding the creation and distribution of Katsina figurines and also examine selected Katsina figurines in …

Proline To Serine Mutation In Flexible Loop Region Of Malate Dehydrogenase, Anna Molstad, Hannah Robertson Apr 2026

Proline To Serine Mutation In Flexible Loop Region Of Malate Dehydrogenase, Anna Molstad, Hannah Robertson

Undergraduate Research Symposium (2026- )

Malate Dehydrogenase (MDH) is an essential enzyme that converts malate to oxaloacetate using the reduction of NAD+ to NADH. In humans, MDH plays a role in energy metabolism by catalyzing a key step of the citric acid cycle, important for energy production. Other indirect roles for MDH include gluconeogenesis and reoxidizing NADH from fatty-acid β-oxidation. An important feature of MDH is a flexible loop region that can alter substrate binding and enzyme activity, but its role is not well understood. Our study investigated how Pro123 to Ser (P123S) mutation in the flexible loop region affects MDH function. We hypothesized that …
