Weeds To Wealth: Upcycling Emilia Sonchifolia To Biobased Batteries, Arielle E. Myerson, Lauren Whetstone

High Impact Practices Student Showcase Spring 2024

Lithium ion (Li-ion) battery technology typically requires graphite as the conductive material for the anodes. Graphite is an unsustainable material which is either synthetically manufactured from fossil fuels or mined and imported. To replace graphite anodes, silicon-based materials such as silicon oxycarbide (SiOC) can be used along with bio-based carbon sources to make even more energy-dense anodes than traditional graphite. The lignins that comprise plant cell walls are an excellent biological source of carbon. Therefore, invasive weeds, such as Emilia Sonchifolia (lilac tassel flower) are a good candidate for building sustainable Li-ion batteries. In this research, the weeds were collected, …

In Vitro Metabolite Identification Of Indole 3-Ylcycloalkyl Ketones, Inez M. Jacobs-Hinton

Graduate Thesis and Dissertation post-2024

Synthetic cannabinoids (SCs) have emerged as a complex and evolving class of compounds designed to mimic the effects of natural cannabinoids, targeting the endocannabinoid system. Despite their widespread recreational use and therapeutic potential, the safety and pharmacokinetic properties of synthetic cannabinoids remain inadequately understood. This study examines the in vitro drug metabolism of a prominent class of SCs—indole-3-ylcycloalkyl ketones—by identifying and characterizing their metabolites. Human liver microsomes were used to investigate the metabolism of several SCs, including (2,2,3,3-tetramethylcyclopropyl)[1-(4,4,4-trifluorobutyl)-1H-indol-3-yl]-methanone (XLR-12), 1-[2-(4-morpholinyl)ethyl]-1H-indol-3-yl-methanone (A-796260), 1-[(1-methyl-2-piperidinyl)methyl]-1H-indol-3-yl-methanone (AB-005), 1-(5-fluoropentyl)-1H-indazol-3-yl-methanone (FAB-144), and 1-[(tetrahydro-2H-pyran-4-yl)methyl]-1H-indol-3-yl-methanone (A-834735).

Non-Catalytic Regulators Of The Secretory Pathway, Peyton Vanwinkle

All ETDs from UAB

This thesis focuses on two key questions: 1) how are bone development and regeneration regulated by the CREB3L1 transcription factor; and 2) what is the mechanism of action of the endoplasmic reticulum resident protein JAGN1, which when dysregulated, causes severe congenital neutropenia (SCN)? CREB3L1 regulates bone development and regeneration in mammalian models by facilitating the expression of COL1A1 and components of the secretory pathway required for collagen secretion. We generated two zebrafish models of Creb3l1 dysfunction (creb3l1ΔbZIP/ΔbZIP and creb3l1TA+/TA+). Both models showed that Creb3l1 functions in regulating col1a1a transcription and overall regenerate size are conserved in zebrafish. However, we also …

Knocking At The Door: The Life And Legacy Of Dr. James Montgomery, Haley Eloise Wells

All ETDs from UAB

The life and work of Black Birmingham cardiologist, Dr. James T. Montgomery, demonstrates the importance of viewing the history of health activism and Birmingham civil rights history as two interconnected histories that influenced each other. Traditionally, secondary scholarship on the Birmingham civil rights movement and scholarship on the history of healthcare have been treated as two separate areas of study. Scholars such as Glenn Eskew and Diane McWhorter have written extensively on the civil rights movement in Birmingham, but their scholarship excludes any comprehensive discussion of the fight for racial justice within Birmingham’s medical field.

Unmasking Molecular Mechanisms Of Multiple Maladies Through Multiomic Methodologies, Luke Potter

All ETDs from UAB

Much modern biomedical research is invested in determining causative molecular mechanisms and identifying potential therapeutics within human disease or injury. Traditional experiments such as over-expressing or “knocking out” the level of a gene’s abundance can determine the specific contribution of a single gene to a pathology and are a vital component of scientific research. However, taking a big picture approach through the application of ‘omics technologies can lead to a broader overall understanding of a pathology and can potentially generate numerous specific hypotheses to be tested using the more traditional molecular approaches. In this dissertation, transcriptomic and epigenomic technologies, measuring …

Mathematical Developments For Bubble Dynamics, Kacie Kulenguski

Graduate Thesis and Dissertation post-2024

This thesis explores bubble dynamics described by the Rayleigh-Plesset equation. The primary focus is on bubble growth. A theoretical discussion of bubble growth is given using the Rayleigh-Plesset equation. This work considers bubble growth in four different cases: a polytropic case without the consideration of surface tension, an isothermal case without surface tension, a polytropic case with surface tension, and an isothermal case with surface tension. Based on these cases, this work develops asymptotic solutions for the evolution of radial bubble growth over time. This thesis provides numerical solutions to these cases through the use of the Runge-Kutta method. These …

Development And Validation Of The Nicotine Vaping Expectancy Questionnaire: Item Generation, Scale Construction, Reliability And Validity, Gabrielle Lynch

Graduate Thesis and Dissertation 2023-2024

Over the past two decades, cigarette smoking has decreased among teenagers and young adults, but nicotine vaping has increased dramatically. Liquid vape products contain harmful chemicals ingested when vapor is inhaled, and vaping is associated with lung damage and chronic obstructive pulmonary disease. There has been relatively little research on nicotine vaping and effective prevention and intervention methods have yet to be developed. Changing expectancy processes has been successful in preventing early alcohol use and cigarette smoking, but little is known about nicotine vaping expectancies. An appropriately developed nicotine vaping expectancy measure is necessary to better understand vaping behavior and …
