Mesoporous Re0.5ce0.5o2-X Fluorite Electrocatalysts For The Oxygen Evolution Reaction, Sreya Paladugu, Ibrahim Munkaila Abdullahi, Harish Singh, Sam Spinuzzi, Manashi Nath, Katharine Page

Chemistry Faculty Research & Creative Works

Developing highly active and stable electrocatalysts for the oxygen evolution reaction (OER) is key to improving the efficiency and practical application of various sustainable energy technologies including water electrolysis, CO₂ reduction, and metal air batteries. Here, we use evaporation-induced self-assembly (EISA) to synthesize highly porous fluorite nanocatalysts with a high surface area. In this study, we demonstrate that a 50% rare-earth cation substitution for Ce in the CeO₂ fluorite lattice improves the OER activity and stability by introducing oxygen vacancies into the host lattice, which results in a decrease in the adsorption energy of the OH* intermediate in …

Energy And Angular Distributions In 250 Ev Electron And Positron Collisions With Argon Atom, K. Tőkési, Robert D. Dubois

Physics Faculty Research & Creative Works

We present energy and angular differential cross sections for single ionization in collisions between electrons and positrons with argon atoms at 250 eV. We treat the collision classically using the three-body approximation where the target atoms are described within the single active electron approximation using a Garvey model potential and only the outermost electron is involved in the collision dynamics. Our present classical trajectory Monte Carlo model is shown to describe the ionization cross sections reasonably well and agree with existing experimental data. We show that the energy distributions, both for electron and positron impact, have the same shape and …

Pinpointing Dream Settings Onto Place Cookies

The International Journal of Ecopsychology (IJE)

Dream reports are short pieces of text, where a dreamer summarizes the remembered experience of nightly dreams. Dream cartography addresses especially the spatial information contained in dream reports. In this context, the current formalization of space in GIScience such as points, lines, polygons, or labels, including place names or addresses, is not sufficient for mapping dream settings. In the best case, dream reports mention place names or streets. However, usually, the perception of space in dreams is designated in terms of whether this is familiar or not, inside or outside, safe or threatening. Moreover, basic comparisons between dream settings are …

Resolving The Topology Of Encircling Multiple Exceptional Points, Chitres Guria, Qi Zhong, Sahin Kaya Ozdemir, Yogesh S.S. Patil, Ramy El-Ganainy, Jack Gwynne Emmet Harris

Michigan Tech Publications, Part 2

Non-Hermiticity has emerged as a new paradigm for controlling coupled-mode systems in ways that cannot be achieved with conventional techniques. One aspect of this control that has received considerable attention recently is the encircling of exceptional points (EPs). To date, most work has focused on systems consisting of two modes that are tuned by two control parameters and have isolated EPs. While these systems exhibit exotic features related to EP encircling, it has been shown that richer behavior occurs in systems with more than two modes. Such systems can be tuned by more than two control parameters, and contain EPs …

Educational Intervention For Delirium Assessment In Intensive Care Units Using The Confusion Assessment Method, Nathan Nguyen, Kaylee Putney, Alana Whittaker

Annual Research Symposium

Delirium frequently occurs in severely ill adults, leading to worse outcomes and increased duration of intensive care unit (ICU) and hospital stays, along with higher associated expenses. The 2018 clinical practice guidelines for Pain, Agitation, Delirium, Immobility, and Sleep Disruption (PADIS) recommend that all adult ICU patients be regularly assessed for delirium. At Valley Hospital Medical Center, the utilization of Confusion Assessment Method for the ICU (CAM-ICU) for monitoring delirium is infrequent, typically taking place either after the adjustment of sedatives or in response to nursing reports of positive neurologic assessments indicating signs of delirium.

Pharmacognosy And Trichomoniasis: A Scoping Review Protocol, Claire Hartwell, Melanie Arslanian, Brad Haubrich

Annual Research Symposium

Trichomoniasis, also called “trich”, is the most common non-viral sexually transmitted infection (STI). Its etiological agent is the protozoan parasite Trichomonas vaginalis, against which first-line antiparasitics usually work. However, resistance is on the rise. Trich has traditionally been considered a nuisance infection, with many (particularly AMAB patients) being asymptomatic. But research in recent years has begun to unravel correlations of trichomonal infections with a myriad of comorbitidies, including infertility, cancers, the pathogenesis of AIDS, and pelvic inflammatory disease (PID). Between the rise of drug resistance and the incidence of these comorbidities, new treatments are needed. In this work, we are …

Evaluating Pi Angle Efficacy Against Established Cephalometric Angular Parameters, Sumit Bohra

Annual Research Symposium

Cephalometrics is a cornerstone of orthodontic diagnosis. Numerous angularmeasurements are used to assess the anteroposterior jaw relation include the ANB angle, Betaangle, Yen angle, and W angle. However, these have limitations, leading to the development of thePi angle. Our study aimed to evaluate the predictability of the Pi angle in a South Indian populationand compare it with other established antero-posterior dysplasia indicators such as the ANB angle,W angle, Yen angle, and Beta angle. This comparison is crucial for determining the most accuratemethod for assessing sagittal skeletal discrepancies.

Chemistry Faculty Research & Creative Works

The rapid rise of carbon dioxide in the atmosphere contributes to global warming and ocean acidification. Carbon capture is considered essential for keeping the atmospheric CO₂ levels from rising further. This work addresses the question of whether nitrogen or oxygen lining of the surfaces of carbon-based CO₂ absorbers is more efficient for CO₂ capture. Polybenzodiazine (PBDAZ) aerogels are carbon-aerogel precursors that were prepared recently (2023) as all-nitrogen structural analogues to well-known polybenzoxazine (PBO) aerogels. However, owing to the fact that the carbonization chemistries of both PBO and PBDAZ aerogels require a prior oxidative aromatization step in air …

Bone marrow lesions (BMLs), occurs from fluid build up in the soft tissues inside your bone. This can be seen on magnetic resonance imaging (MRI) scans and is characterized by excess water signals in the bone marrow space. This disease is commonly caused by osteoarthritis (OA), a degenerative join disease where tissues within the joint breakdown over time [1]. These BMLs are an emerging target for OA, as they are commonly related to pain and worsening of the diseased area until surgical intervention is required [2]–[4]. In order to assess the BMLs, MRIs were utilized as input into a regression …

Physiological Impact Of Ergot Alkaloid Consumption In Ruminant Livestock, J. L. Klotz, S. K. Duckett, D. L. Harmon

IGC Proceedings (1997-2023)

Ergot alkaloids in feeds and forages are a worldwide concern. Consumption of ergot alkaloids by ruminant livestock can range from extreme cases that threaten the life of the animal to more frequent and chronic outcomes where livestock productivity is decreased. Consumption of ergot alkaloids alters ruminant physiology such that it outwardly manifests in lower animal intake and gain, decreased reproductive efficiency, and a compromised circulatory system. This talk will cover current research that is improving our understanding of how ergot alkaloids alter cell and tissue physiology that results in the compromised growth and reproduction observed at the whole animal level.
