Development And Utility Of Single Sperm Genetic Analysis Methods To Aid In Sexual Assault Investigations, Morgan S. Grim

Graduate Thesis and Dissertation post-2024

Following a sexual assault, the ability to obtain an autosomal short tandem repeat (aSTR) profile of a semen contributor diminishes rapidly and is often not possible for intervals exceeding 48-72 hours. This partially stems from limitations with DNA extraction and typing systems used. Routine analysis typically uses differential extraction (i.e. separating sperm and non-sperm cells). This can make fragile sperm prematurely lyse, causing the sperm DNA to become overwhelmed by the amount of victim epithelial DNA. While Y-chromosome STRs (Y-STRs) target male DNA despite abundant female DNA, Y-STR haplotypes are less discriminatory than aSTR profiles. To address these issues, this …

Catalytic Interfaces Of Earth-Abundant Metals Copper And Nickel Chalcogenides For Hydrogen Evolution Catalyst, Manuel Alejandro Ramirez Ubillus

Graduate Thesis and Dissertation post-2024

This dissertation establishes design principles for earth-abundant catalysts used in the hydrogen evolution reaction (HER), showing that electroactivity is primarily controlled by structural features such as surface facet exposure, dopant content, and dynamic phase transformations. These factors influence conductivity, active site density, and stability, as demonstrated through three model systems: Cu₂O, NiSe₂, and Cu₂S. Cu₂O particles with controlled shapes were synthesized to explore the relationship between facet exposure and catalytic activity. Octahedra dominated by the facet 111 performed better than cubes rich in the facet 100. Combining Cu₂O with reduced graphene oxide further improved conductivity, dispersion, and stability, leading to …

A Greener Way To Synthesize Biodiesel: Mechanochemistry With No Added Catalyst, Amanda S. Tanner

Among these, the lead degrader induced up to 92% degradation of SOS1 in CRC cell lines and patient‑derived organoids (PDOs), with excellent specificity. In parallel, an AICAR‑derived PROTAC targeting the transmembrane oncoprotein MUC1‑CT in EGFR‑mutant lung cancer achieved time‑dependent and partial target degradation, establishing complementary chemical tools to probe intracellular signaling and …

A Substitutional Solid Solution Approach To Exploring Dipoles And Chirality In Mofs., Kyle R. Langlois

Graduate Thesis and Dissertation post-2024

In this work substitutional solid solutions of dipolar and chiral MOFs were made with predetermined structure, composition, and function. Through encoding the dipoles and chirality into the organic linkers and varying their incorporation into cubic porous interpenetrated zirconium MOF system the bulk dipolar and chiral properties were assessed. Specifically, the real and imaginary components of the polarization properties in respect to the dipoles and the optical properties in respects to chirality. It was found the bulk properties are dependent on the crystal structure and the inherent porosity of the MOFs themselves.
