Interfacial Engineering Of Electrodes And Solid-State Electrolytes For High-Performance Lithium-Ion And Sodium-Ion Batteries, Ahmad Helaley

McKelvey School of Engineering Graduate Student Theses & Dissertations

The rapid expansion of electrified transportation and renewable energy integration demands advanced lithium-ion (Li-ion) and sodium-ion (Na-ion) batteries with enhanced safety, long-term reliability, and high energy efficiency. However, conventional systems employing liquid electrolytes continue to exhibit persistent failure modes, including thermal instability, parasitic interfacial reactions, transition-metal dissolution, and electrode degradation under high-voltage or fast-charging conditions. These limitations become even more critical in solid-state configurations, where insufficient ion mobility and interfacial incompatibility can severely restrict electrochemical performance. The first part of this dissertation develops an atomic-layer-scale interfacial stabilization strategy using atomic layer deposition (ALD) coatings. ZnO-modified graphite anodes in Li-ion cells …

An International Human Rights-Based Approach To Reducing Maternal Mortality And Enhancing Safe Motherhood In Africa, John Mukum Mbaku

San Diego International Law Journal

In 2015, the U.N. General Assembly (UNGA) noted that almost fifteen years after the global community had agreed to the Millennium Development Goals (MDGs), which provided an important framework for economic and human development, significant progress has been made in several areas. However, the UNGA explained that many developing countries have not been able to achieve the MDGs, especially those goals related to maternal and reproductive health. Although the global maternal mortality rate has declined significantly, only 50% of pregnant women in developing countries receive the recommended minimum of four antenatal care visits. Additionally, complications suffered during pregnancy and childbirth …

Seamless Security: Reforming Export Controls For A Stronger Allied Defense Industrial Base, Justin Belcher

San Diego International Law Journal

Russia’s invasion of Ukraine and China’s accelerating military modernization underscore the need for the United States and its allies to reinforce their defense industrial bases to deter and prevail in future conflicts. This paper examines the historical and strategic foundations driving the need for export control reform, identifies key U.S. export control laws governing defense coproduction and co-development, and analyzes how current regulations constrain allied industrial integration. It concludes by proposing solutions to streamline export control regulations to improve the strength and resilience of the modern defense industrial base.

Exonuclease/endonuclease/phosphatase (EEP)-fold hydrolases are canonically monomeric phosphodiesterases exemplified by APE1, DNase I, and TDP2 nucleases. While EEP family domain containing protein 1 (EEPD1) acts in DNA stress responses, its proposed nuclease activities are enigmatic. Here, we integrate hybrid structural methods, evolution, biochemistry, cancer genomics, plus molecular and cell biology to define EEPD1 structure, assembly, and function at stalled DNA replication forks. Results imply EEPD1 surprisingly requires both unique EEP domain dimer and distinctive tandem Helix-hairpin-Helix [(HhH)2] domains to clamp double-stranded (ds) DNA at reversed DNA replication forks for fork protection. Small-angle X-ray Scattering (SAXS), crystal, and cryo-EM structures unveil an …

Accurate monitoring of Chlorophyll-a (Chla) is critical for assessing aquatic ecosystem health, yet ecological complexity often leads to ambiguous spectral signatures in satellite data. Traditional deterministic models assume a one-to-one mapping between spectra and pigments, often failing to capture these high-dimensional analytical challenges. In this study, we propose a novel deep learning architecture, the Channel Attention-Mixture Density Network (CA-MDN), to retrieve Chla from the National Aeronautics and Space Administration (NASA) Earth Surface Mineral Dust Source Investigation (EMIT) hyperspectral mission. The CA-MDN integrates an attention mechanism to dynamically select ecologically relevant spectral bands and employs a probabilistic output layer to quantify …

Human Bone Marrow-Mesenchymal Stem Cells Differentiation Into Brain-Like Endothelial Cells, Yomna Soliman, Güli̇n Baran, Nur Mustafaoğlu

Turkish Journal of Biology

Background/aim: Brain microvascular endothelial cells (BMECs), which constitute the blood–brain barrier (BBB), are essential for maintaining central nervous system homeostasis. Like BMECs, multipotent mesenchymal stem cells (MSCs) originate from the mesodermal lineage. Thus, MSCs may serve as a direct and efficient cellular source for BMEC-like differentiation. Notably, differentiation of human induced pluripotent stem cells (hiPSCs) into BMECs typically involves a 2-step protocol: inducing mesodermal commitment followed by endothelial specification. In contrast, direct differentiation from MSCs could bypass the initial mesodermal induction step, offering a streamlined alternative. This study tested a novel strategy for differentiating MSCs into brain-like endothelial cells (BLECs), …

Pharmacy Faculty Scholarship

Pancreatic ductal adenocarcinoma (PDAC) is the most lethal form of pancreatic cancer, with poor prognosis driven by late diagnosis, therapeutic resistance, and an immunosuppressive tumor microenvironment. Interactions between tumor cells and immune cells promote immune evasion and tumor progression, limiting the efficacy of immune checkpoint blockade and other immunotherapies. Given the high expression of trophoblast cell surface antigen 2 (TROP2) in PDAC, we developed a TROP2-targeted Toll-like receptor 7 (TLR7) agonist (E104) designed for selective accumulation within the tumor microenvironment to activate antitumor immunity. Although antibody bioactivity is traditionally linked to Fcγ receptor (FcγR) engagement and recruitment of effector cells, …

BACKGROUND. The SARS-CoV-2 pandemic provided a rare opportunity to study how human immune responses develop to a novel viral antigen delivered through different vaccine platforms. However, to date, no study has directly compared immune responses to all 3 FDA-approved COVID-19 vaccines at single-cell multiomic resolution.

METHODS. We longitudinally profiled SARS-CoV-2–naive adults (n = 31) vaccinated with BNT162b2, mRNA-1273, or Ad26.COV2.S, integrating plasma cytokines, antibody titers, and single-cell multiomic data (DOGMA-Seq).

RESULTS. We discovered a distinct, transient IFN program termed ISG-dim, which emerged specifically 1–2 days after the first mRNA dose in approximately 10% of myeloid cells. This state was …

Structure–Activity Modeling And Hybrid Machine Learning-Based Prediction Of Bioactivity In Pyrazole Derivatives For Drug Discovery Applications, Kader Şahi̇n, Serhat Kiliçarslan, Serdar Durdaği, Emi̇n Saripinar

Turkish Journal of Biology

Background/aim: Pyrazole derivatives are of growing interest due to their diverse pharmacological activities. However, their biological activity is often highly sensitive to subtle structural modifications. Existing quantitative structure–activity relationships (QSAR) approaches frequently fail to capture the conformational flexibility and nonlinear structure–activity relationships (SAR) of such heterocyclic scaffolds, creating a gap in the accurate prediction of their biological profiles. Therefore, there is a strong need for more robust and predictive computational frameworks. This study addresses this gap by integrating four-dimensional (4D)-QSAR descriptors with hybrid machine learning (ML) techniques to improve predictive accuracy and provide a more reliable tool for structure-based drug …
