Scaling The Polymerization Of Polyaldehydes Through Continuous Flow Synthesis, Jared M. Schwartz, Paul A. Kohl, Anthony Engler

Faculty Publications

A plug flow reactor was constructed to scale the synthesis of metastable, phthalaldehyde-based polymers to achieve production rates of 1–2 kg per day. The flow-induced mixing and in-line polymerization quench and precipitation sequences resulted in improved polymer purity and long-term stability compared to the same materials made from a conventional batch process. Cryogenic rheology was used to probe the complex fluid dynamics encountered during the polymerization of PPA homopolymers. It is envisioned that this continuous flow manufacturing approach could be extended to other low ceiling temperature or aldehyde monomer systems to help implement and support a plastic circular economy. Graphical …

Machine Learning For Automated Classification Of Lung Collagen In A Urethane-Induced Lung Injury Mouse Model, Khalid Hamad Alnafisah, Amit Ranjan, Sushant P. Sahu, Jianhua Chen, Sarah Mohammad Alhejji, Alexandra Noël, Manas Ranjan Gartia, Supratik Mukhopadhyay

Faculty Publications

Dysregulation of lung tissue collagen level plays a vital role in understanding how lung diseases progress. However, traditional scoring methods rely on manual histopathological examination introducing subjectivity and inconsistency into the assessment process. These methods are further hampered by inter-observer variability, lack of quantification, and their time-consuming nature. To mitigate these drawbacks, we propose a machine learning-driven framework for automated scoring of lung collagen content. Our study begins with the collection of a lung slide image dataset from adult female mice using second harmonic generation (SHG) microscopy. In our proposed approach, first, we manually extracted features based on the 46 …

Fishnet Of Connection: The Cultural And Ecological Resilience Of Samoan Fishers, Megan Wong

Samoa: Social and Environmental Change in Oceania

Samoan fishers have created extensive knowledge systems both historically (as traditional knowledge) and contemporarily (local knowledge), and individually and collectively through close interaction with the marine environment. Such knowledge has yet to be recorded in literature, and thus cannot be brought into discussions of cultural and ecological resilience in the face of a changing environment. To remedy this, talanoas were used in this research to holistically understand how subsistence, commercial, and game fishers in Samoa perceive and interact with their communities and the environment. Fishers were found to undertake the task of fishing for nutrition, income, leisure, community, and tradition. …

Rate Convenants In Municipal Bonds: Selling Away Civil Rights And Fair Housing Goals, Jade A. Craig

Denver Law Review

State and local governments across the United States issue municipal bonds to raise capital to cover infrastructure projects. Jurisdictions issue revenue bonds to fund projects ranging from improvements to public utilities and toll roads to convention centers and retirement communities. These revenue bonds often include a rate covenant, a provision in which the local government issuer assures bondholders that the user fees the project raises will adequately service the debt. These covenants generally do not reserve state and local governments the right to lower rates in the public interest, nor do they impose a restriction on how high the rates …

Intoxicated Scootering: Rethinking Electric Scooter Liability In Washington, David Goodwin

Washington Law Review

The widespread acceptance of electric scooters has transformed the landscape of urban transportation. Yet, the emerging phenomenon of intoxicated scootering poses unanswered questions of liability and accountability. New research indicates that a third of traumatic electric scooter injuries are associated with intoxicated scootering. This statistic is particularly alarming given that there are over fifty million scooter trips per year in the United States.

In Washington State, the State Legislature has not enacted a state-wide policy against intoxicated scootering. Instead, the Legislature delegates the authority to regulate the operation of electric scooters to local governments. Due to the ambiguity of whether …

Field-Ready Voltammetric Detection Of Aqueous Cadmium (Ii) Ions On Aptamer-Modified Inkjet-Printed Gold Electrode, Glenn D. Ongayo, Jiena Lynne R. Pauco, Erwin P. Enriquez

Chemistry Faculty Publications

In this work, a simple and cost-effective integrated electrode system consisting of aptamer-modified inkjet-printed (IJP) gold working electrode and unmodified IJP gold as counter electrode (both printed on polyethylene naphthalate substrate) has been developed for low-cost detection of cadmium (II) ion in water. The technique uses a Cd2+ (Cd-4) aptamer, a single-stranded DNA with 31 nucleotides trapped on the working electrode using the self-assembly monolayer (SAM) technique. The electrochemical detection of Cd2+ is based on the change in redox peaks of [Fe(CN)6]3-/4- as a redox probe in cyclic voltammetry. The change in peak current is caused by a difference in …

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 …

White Monsters: Understanding Whiteness As Social And Legal Monstrosity, Steven Sacco

Cardozo Journal of Equal Rights & Social Justice

The article argues that whiteness operates as a socially and legally constructed monstrosity, perpetuating systemic inequality and destructive power through both intentional and nonintentional mechanisms. By employing monster theory, the analysis reveals how whiteness adapts and evolves to maintain its dominance, often through legal frameworks that obscure its harmful effects. The Supreme Court's decision in Plyler v. Doe, while advancing justice in some aspects, also exemplifies how the law can perpetuate inequality by overlooking historical and social contexts.

Employing Multi-Omics Analyses To Understand Changes During Kidney Development In Perinatal Interleukin-6 Animal Model, Ganesh Panzade, Tarak Srivastava, Daniel P. Heruth, Mohammad H. Rezaiekhaligh, Jianping Zhou, Zhen Lyu, Mukut Sharma, Trupti Joshi

Biomedical Sciences

Chronic kidney disease (CKD) is a leading cause of morbidity and mortality globally. Maternal obesity during pregnancy is linked to systemic inflammation and elevated levels of the proinflammatory cytokine interleukin-6 (IL-6). In our previous work, we demonstrated that increased maternal IL-6 during gestation impacts intrauterine development in mice. We hypothesized that IL-6-induced inflammation alters gene expression in the developing fetus. To test this, pregnant mice were administered IL-6 or saline during mid-gestation. Newborn mouse kidneys were analyzed using mRNA-seq, miRNA-seq and whole-genome bisulfite-seq (WGBS). A multi-omics approach was employed to quantify mRNA gene expression, miRNA expression and DNA methylation, using …

Substrate Interference And Strain In The Second-Harmonic Generation From Mose2 Monolayers, Sudeep Puri, Sneha Patel, Jose Luis Cabellos, Luis Enrique Rosas-Hernandez, Kaitlin Reynolds, Hugh O.H. Churchill, Salvador Barraza-Lopez, Bernardo S. Mendoza, Hiroyuki Nakamura

Physics Faculty Publications and Presentations

Nonlinear optical materials of atomic thickness, such as non-centrosymmetric 2H transition metal dichalcogenide monolayers, have a second-order nonlinear susceptibility (χ⁽²⁾) whose intensity can be tuned by strain. However, whether χ⁽²⁾ is enhanced or reduced by tensile strain is a subject of conflicting reports. Here, we grow high-quality MoSe₂ monolayers under controlled biaxial strain created by two different substrates and study their linear and nonlinear optical responses with a combination of experimental and theoretical approaches. Up to a 15-fold overall enhancement in second-harmonic generation (SHG) intensity is observed from MoSe₂ monolayers grown on SiO₂ when …
