Bioluminesence-Induced Photoredox Catalysis And Its Mechanisms, 2024 Rowan University
Bioluminesence-Induced Photoredox Catalysis And Its Mechanisms, Dominic Jeffrey Bates
Theses and Dissertations
The bioluminescence-induced photoredox reaction (BIPR) is a novel methodology developed to overcome the limitations of photo-induced chemistry by initiating chemical work using bioluminescent Escherichia coli as a photon source. In industry, photochemistry is superseded by thermochemical reaction processes. Despite its massive potential, there are very few applications in industry for photochemistry. Unlike thermochemistry, reaction scale-ups are not as easy as simple dimensional increases in a reaction vessel due to the nature of light. This deficiency is seemingly overcome through the development of flow technologies; however, the overall yield of such methods remains incomparable with those utilizing thermochemistry. This thesis focuses …

Solubility Characterization Of Organic Molecules For Aqueous Organic Redox Flow Batteries, Anthony W. Ferrell, Harkeerith K. Vij, Seamus D. Jones
College of Engineering Summer Undergraduate Research Program
The major obstacle to renewable energy sources is a lack of long-term energy storage capabilities. Energy produced during the day dissipates, leaving insufficient electricity for at night. The goal of the project is to design an Aqueous Organic Redox Flow Battery (AORFB) to act as long-term energy storage. Work has been done using machine learning to identify suitable compounds for the batteries. In this work there was no indication as to the aqueous solubility of the molecules; this controls the device’s energy storage capabilities. We used a machine learning model to determine the aqueous solubility of slightly more than 3000 …

Economic Impacts Of Establishing A Neutron Source Facility In Windsor, 2024 University of Windsor
Economic Impacts Of Establishing A Neutron Source Facility In Windsor, Abdur Rahman
Major Papers
Cancer poses a significant health challenge in Canada, with two in five individuals likely to develop the disease. This paper explores the economic impacts of establishing a prototype compact accelerator-based neutron source (PC-CANS) facility in Windsor that will produce medical isotopes locally in Windsor, Ontario, rather than relying on centralized production and transportation from London, Ontario. Fluorine-18 medical isotopes, crucial for positron emission tomography (PET) scans, experience significant decay losses during transportation due to their short half-life of 109.8 minutes, increasing costs and restricting availability. Using a differential analysis approach, the study quantifies economic benefits, focusing on three main impacts: …

A Preliminary Fuzzy Inference System For Predicting Atmospheric Ozone In An Intermountain Basin, 2024 Utah State University
A Preliminary Fuzzy Inference System For Predicting Atmospheric Ozone In An Intermountain Basin, John R. Lawson, Seth N. Lyman
Mathematics and Statistics Faculty Publications
High concentrations of ozone in the Uinta Basin, Utah, can occur after sufficient snowfall and a strong atmospheric anticyclone creates a persistent cold pool that traps emissions from oil and gas operations, where sustained photolysis of the precursors builds ozone to unhealthy concentrations. The basin's winter-ozone system is well understood by domain experts and supported by archives of atmospheric observations. Rules of the system can be formulated in natural language ("sufficient snowfall and high pressure leads to high ozone"), lending itself to analysis with a fuzzy-logic inference system. This method encodes human expertise as machine intelligence in a more prescribed …

Journal of the South Carolina Academy of Science
Parkinson’s disease (PD) is a progressive neurodegenerative disorder characterized by motor impairments and non-motor symptoms, significantly impacting patients' quality of life. Currently, cerebrospinal fluid (CSF) is the primary biofluid used for PD biomarker studies, notably α-synuclein, despite the invasive nature of lumbar puncture procedures. Recent work has shown that some of these PD biomarkers have been measured in saliva. As an alternative to CSF, saliva can be non-invasively self-collected by patients repeatedly over time to monitor biomarker levels. However, the stability of these biomarkers in saliva needs to be evaluated before saliva can be considered for patient self-collection studies. Therefore, …

Michigan Tech Publications, Part 2
Mixed-phase clouds affect precipitation and radiation differently from liquid and ice clouds, posing greater challenges to their representation in numerical simulations. Recent laboratory experiments using the Pi Cloud Chamber explored cloud glaciation conditions based on increased injection of ice-nucleating particles. In this study, we use two approaches to reproduce the results of the laboratory experiments: a bulk scalar mixing model and large-eddy simulation (LES) with bin microphysics. The first approach assumes a well-mixed domain to provide an efficient assessment of the mean cloud properties for a wide range of conditions. The second approach resolves the energy-carrying turbulence, the particle size …

Enhancing Cardiomyocyte Resilience To Ischemia-Reperfusion Injury: The Therapeutic Potential Of An Indole-Peptide-Tempo Conjugate (Iptc), Shanshan Hou, Xin Yan, Xiang Gao, Steffen Jockusch, K. Michael Gibson, Zhiying Shan, Lanrong Bi
Michigan Tech Publications, Part 2
Ischemia/reperfusion (I/R) injury leads to apoptosis and extensive cellular and mitochondrial damage, triggered by the early generation and subsequent accumulation of mitochondrial reactive oxygen species (mtROS). This condition not only contributes to the pathology of I/R injury itself but is also implicated in a variety of other diseases, especially within the cardiovascular domain. Addressing mitochondrial oxidative stress thus emerges as a critical therapeutic target. In this context, our study introduces an indole-peptide-tempo conjugate (IPTC), a compound designed with dual functionalities: antioxidative properties and the ability to modulate autophagy. Our findings reveal that IPTC effectively shields H9C2 cardiomyocytes against hypoxia/reoxygenation (H/R) …

Application Of High-Resolution Nano-Scale Liquid Chromatography Tandem Mass Spectrometry To The Study Of S. Endobioticum-Induced Infection In Cultivated Potatoes, Daria Baskova
Electronic Thesis and Dissertation Repository
Potato wart is an infection of cultivated potato plants caused by the soil-borne biotrophic fungus Synchitrium endobioticum. The main symptoms of infection are formation of warts on the tuber tissue and the production of biflagellated mobile spores that undergo long-lasting dormancy periods. Genomic studies have significantly contributed to an overall understanding of the fungal life cycle, including the discovery of the first S. endobioticum avirulence genes, and the identification of multiple pathotypes. However, the molecular pathways involved in host-pathogen interactions during potato wart infection and the factors contributing to resistance in plants remain unknown. In this work, a combination …
