Effect Of Inclusion Complexes Of Ferrocene On Catalytic Activity Of Fenton’S Reaction, Lakshmi Priyanka Gudipati
Effect Of Inclusion Complexes Of Ferrocene On Catalytic Activity Of Fenton’S Reaction, Lakshmi Priyanka Gudipati
Electronic Theses and Dissertations
Ferrocene is an orange solid with a camphor-like odor and is soluble in almost all organic solvents. It is known for its remarkable stability, as it is unaffected by air, water, and strong bases. Ferrocene derivatives also have great potential as anticancer and antimalarial agents, but their practical insolubility in water can limit their utility as a pharmaceutical active ingredient. In this study, the main aim is to form inclusion complexes between different ferrocene derivatives and hydroxypropyl-β-cyclodextrin (HP-β-CD) to enhance their water solubility and use the resulting complexes to test for cleavage of methylene blue ethanolamine (MB-EA) through Fenton's reaction …

"Sealed With A Kiss On Your Artery": An Archive Of Southern Lesbian Desire, Sarah Margaret Heying
Electronic Theses and Dissertations
This dissertation examines southern lesbian feminist print culture of the 1970s-2000s, which produced some of the most intersectional work to come out of second-wave feminism— especially in terms of creative and critical challenges to anti-Blackness, classism, metrocentrism, and regional exceptionalism. A central contribution of “Sealed with a Kiss on Your Artery” is its reimagination of archival reading practices from a queer-feminist literary studies perspective. Each chapter examines the archive of a particular lesbian feminist figure and demonstrates a corresponding interpretive practice; I seek to encounter these historical figures in a manner befitting not only the facts of their contributions to …

Exploring Structure-Activity Relationships In Molecular Catalysts For C-H Bond Oxidation And Co2 Reduction, Zane Turner
Exploring Structure-Activity Relationships In Molecular Catalysts For C-H Bond Oxidation And Co2 Reduction, Zane Turner
Electronic Theses and Dissertations
Value-added chemicals can be generated by the functionalization of hydrocarbon substrates by C-H bond oxidation and by the reduction of carbon dioxide (CO2), where each of these processes require long-lived catalysts that are selective and efficient. Chemical feedstocks such as petroleum-derived hydrocarbons and carbon dioxide are inexpensive and readily accessible but are challenging to transform into more valuable compounds. The oxidative functionalization of unactivated C-H bonds is a difficult task because they are, in general, thermodynamically stable and kinetically inert. Bioinspired iron-oxo catalysts have shown great promise in this area, but often have limited activity, selectivity, and/or stability. In this …

Exploring Disparities In Prenatal Smoking And The Role Of Adverse Childhood Experiences, Patricia Da Rosa
Electronic Theses and Dissertations
Cigarette smoking is the most common cause of premature death, killing half of its users. During pregnancy, smoking continues to be the leading cause of premature death for both mothers and newborns. Research has consistently demonstrated smoking is not randomly distributed across populations; it is, instead, socially patterned. Women from lower socioeconomic backgrounds, those experiencing mental health issues, and rural area residents are disproportionately affected. The life course framework emphasizes the impact of exposures in early life on shaping health inequities. Eliminating health inequities, including risky behaviors such as smoking, requires an understanding of the pathways that generate these inequities. …

Electronic Theses and Dissertations
Regenerative agriculture is a pressing matter for the dairy industry to address cropland sustainability and carbon sequestration. One regenerative management practice that has been identified to help with row crop sustainability for key metrics like soil organic carbon (SOC) is complex covers. When producers use complex covers one of the main challenges is that it takes time to detect a change in SOC. However, simulation models are a tool that can be used to help determine if a regenerative practice is a strategy that gives the best results (i.e., increased SOC) while aligning with long-term production goals. Therefore, our objectives …

Walleye Feeding, Movements, And Energetics Reveal The Importance Of Connected Wetlands In Glacial Lakes, Logan M. Cutler
Walleye Feeding, Movements, And Energetics Reveal The Importance Of Connected Wetlands In Glacial Lakes, Logan M. Cutler
Electronic Theses and Dissertations
Fish require a variety of resources including prey, thermal refugia, and different physical habitat characteristics to grow and reproduce. All necessary resources are rarely provided by a single habitat, resulting in tradeoffs between occupying different habitats; therefore, the ability to move among heterogenous habitats is critical. These tradeoffs may occur in lakes with connected wetlands where the main lake habitats tend to be more thermally stable, but wetlands often provide more diverse and abundant prey. For my second chapter, I compared prey diversity and abundance as well as Walleye (Sander vitreus) diets and condition in a large glacial lake (Lake …
