Investigating the Catalytic Applications of Trisox when Bound to Metals: Cobalt (II), Nickel (II), Copper (II)
No full textRecord ID: 5
Award(s): Excellence in Research Communication
Program Affiliation: Capstone
Presentation Type: Poster
Abstract: Trisox is a versatile ligand that could be utilized as catalysts in chemical reactions to help further the knowledge of coordination chemistry. Studying coordination chemistry can assist in showing how different molecules interact with each other to form metal complexes. Trisox ligands, as the name suggests, contain three oxygen atoms which includes monomeric, six-coordinate, pseudo-octahedral geometries. In this study, novel metal complexes of Trisox ligands with Cobalt (II), Nickel (II), and Copper (II) were synthesized and characterized to analyze oxidation reactions that use air as an oxidant. The synthesis involved the coordination of the Trisox ligand with the respective metal salts, followed by recrystallization to obtain pure crystalline products. Nuclear Magnetic Resonance (NMR) spectroscopy was utilized to confirm the structures and interpret the coordination environments of the metal complexes. Further characterization through mass spectrometry provided additional insights into the molecular composition and fragmentation patterns of these metal complexes. Further studies will involve the use of UV-Vis spectroscopy to analyze the electronic transitions within the metal complexes which could offer insight into the electronic structures and potential optical properties. Overall, this study contributes to the expanding field of coordination inorganic chemistry by introducing new Trisox metal complexes to explore further catalytic, chemical, and optical properties.

Award(s): Excellence in Undergraduate Research Mentorship
Program Affiliation: UPRISE Summer Research Program
Presentation Type: Poster
Abstract: Diploptera punctata, the pacific beetle mimic cockroach, are one instance of over 65 convergent evolutions of live birth in insects alone. Of interest are the common pressures which lead to shared features of live birth, such as urogenital and circulatory system remodeling, placental structures, and changes to the endocrine system. Investigated during this study were factors related to pregnancy and circadian rhythm; one arm focused on studying changes in behavior and sleep during pregnancy, and the other on the effects of chronic sleep deprivation on pregnancy, such as gestational period and milk protein transcript levels. Study of these factors has revealed that chronic disturbance of sleep during pregnancy negatively impacts embryo development, increasing gestational duration and decreasing the transcription of milk proteins. In addition, scavenging and risk taking behavior are significantly altered during pregnancy. These findings indicate that sleep is key to embryo development and that pregnancy has a significant impact on behavior and daily rhythms in Diploptera Punctata.

No full textRecord ID: 163
Program Affiliation: Capstone
Presentation Type: Poster
Abstract: How do you know when a scoping review is a good fit for your literature review? As an undergraduate student, I participated in a project where our goal was to analyze commonly employed methodologies used to assess gender perception in speech, demographic characteristics of listeners that have been recorded, and the types of speech samples being utilized to investigate gender perception for speech pathology. However, there are many literature review styles to choose from before moving forward with a project or idea. We found that a scoping review would be the most appropriate tool to meet our goals because it highlights literature in emerging areas of science that have not been reviewed. A scoping review assesses the potential scope of research done about a certain topic in hopes of retrieving evidence on the team\u27s research topics. To conduct our scoping review, we used the software, Covidence, which allows reviewers to complete article screening and data extraction quickly and flexibly. Articles went through multiple stages, abstract and title screening, full-text screening, and data extraction, to be filtered and eventually included in our findings. Through this experience in reviewing literature, I have gained knowledge on the benefits and disadvantages of scoping reviews, how to navigate through research article sections, and how to create a thought pattern that seeks out information for future research questions related to health disparities.

Program Affiliation: NA
Presentation Type: Poster
Abstract: The ancient city of Calakmul, once a leading polity of the Classic Maya world, has drawn the attention of scholarly investigation for nearly a century. Despite the long history of academic research, the intricate relationship of the densely populated center with its surrounding tropical forest environment has only recently come into clear focus. How did they provide adequate supplies of food and forest products to expanding populations during an occupation that lasted well over a millennium? These and other questions have been the focus of a recent study conducted by a multidisciplinary team of biologists, geographers and archaeologists. In this poster we will address these questions using the identification of wood remains using a combination of light and Scanning Electron Microscopy

Abstract: Climate change is affecting the yield, quality, and resiliency of our crops. With The City of Cincinnati already addressing food insecurity through the Green Cincinnati Plan, this Research aims to specifically address the impact, and possible mitigation, of climate change on our agricultural industry. Topics researched include, most at risk crops, responses from other areas within the United States, and possible opportunities for new crops. The outcome of this research will further the strategic response to climate change in our urban agricultural industry, allowing for the possibility of decreased food insecurity, and increased food resiliency in our city. The next steps would be to partner with our local growers to implement these strategies and help improve the resilience of our urban agricultural industry. 
Green Cincinnati Plan: Addressing Environmental Issues through Support of Business Owners and Start-ups

Award(s): Excellence in Research Communication
Program Affiliation: Capstone
Presentation Type: Poster
Abstract: The business market is one of the largest contributors to environmental problems, but many organizations are unsure of how to change their practices to become a "green" business. The city of Cincinnati has adopted the quinquennial Green Cincinnati Plan (GCP) in order to address the various environmental problems plaguing our city, including market issues. This raises the questions of: How can the Green Cincinnati Plan and its partners aid in supporting local businesses, specifically minority and woman owned, in enacting green practices to address environmental issues? Is this even a feasible goal in the city of Cincinnati? Through research of the current state of this GCP goal, it has been found out that there are attempts at supporting small businesses in becoming a green business through organizations such as 513 Green and 2030 District. There is little to no attempt yet in the city of Cincinnati to offer incentives for sustainable businesses practices, nor any solutions targeted specifically at minority or woman owned businesses. It is evidenced that there is a demand for green businesses from consumers, but what is the benefit for business owners? Have other cities adopted incentive programs for small businesses to enact sustainability plans, and would they be a model for Cincinnati? The outcome of the work will further help Cincinnati and other cities to adopt solutions to aid business owners in implementing sustainable practices. Supporting businesses in adopting sustainable practices is beneficial for addressing pressing environmental concerns that threaten the preservation of our natural environment.

Award(s): Excellence in Research Communication
Program Affiliation: NA
Presentation Type: Poster
Abstract: This project aims to investigate the clinical outcomes and feasibility of 3D printed anatomical models and digital surgical planning that assist in the preoperative surgical planning of endoscopic mitral valve repair and replacement in 5 patients. Due to the complex nature of the minimally invasive procedure, the choice of the entry point in the chest for the surgery has a critical bearing on the outcome. Using advanced computer-aided design and 3D printing, the working port placement was pre-planned before the surgery. Additionally, angular measurements of the valve planes and skin measurement of the entry point were provided to the cardiothoracic surgeon as part of the digital surgical plan. The electronic medical record of the 5 patients will be reviewed to assess the clinical outcomes including any intraoperative, short term, and long-term complications. The project will add new knowledge to the literature on the clinical utility of endoscopic mitral valve repair and replacement using 3D printing and digital surgical planning. Furthermore, in terms of the development of my own discipline and personal growth, through performing this project, I will gain an improved understanding of the possible integrations of engineering with medicine as well as the steps involved in analyzing patient medical records which will assist in my aspirations of becoming a future physician.

Program Affiliation: Capstone
Presentation Type: Video
Abstract: Biodiversity is one of the most important aspects when working to maintain ecosystem health. We can gather a lot of information based on the species that live in an area such as: pollution via pollution intolerant species, ecosystem relationships, ecosystem stability, and resistance to forces such as climate change. In order to improve the biodiversity of an ecosystem, an area needs to first assess what biodiversity they currently have. Analyzing the number and types of species that exist in an area can be a highly tedious task, and seem almost impossible in large city areas.The goal of this study is to answer the following questions presented by the Green Cincinnati plan, what biodiversity assessments exist already? What are the major gaps? What do experts view as being needed most? What tools, such as apps, exist to support citizen science in this area? In this study, we aim to analyze the viability of a biodiversity assessment specifically in the city of Cincinnati. First, we analyze what current biodiversity data is available for the city. Then we compare this information to similar reports that have been completed in other larger cities. We also aim to expand on what current citizen science exists in this area, to maximize public involvement in the environment.

Program Affiliation: NA
Presentation Type: Podium
Abstract: Climate change is a growing problem worldwide, with around 42% of global CO2 emissions coming from the built environment (cite). Education facilities like our public schools can serve as a model for environmental best practices by adopting sustainably vehicles like buses, reducing fossil fuel use in heating and cooling, constructing more light-reflective buildings, and reducing food waste. In this project, I investigated which schools in the United States are successfully adopting these techniques and which would be most easily adopted by Cincinnati. This project is ongoing, but my research found that the Department of Education has a Green Ribbon School program designed specifically for sustainability in schools. This program has been, and will continue to be, vital for helping the City of Cincinnati in their emissions reductions goals, as well as influencing future generations to explore green infrastructure
The Impact of Rising Temperatures on Wolf Spider Phenology

Award(s): Excellence in Undergraduate Research Mentorship
Program Affiliation: Capstone
Presentation Type: Poster
Abstract: Climate change is one of the defining challenges of our time, and accelerating global warming is a destabilizing factor for ecosystems in every corner of the world. As ectotherms, invertebrates are expected to be affected by our changing climate, with warmer temperatures causing faster growth rates. The goal of this research is to understand what impact rising temperatures due to climate change have had on the phenology, or annual life cycle of the wolf spider, Schizocosa ocreata. In order to quantify this relationship, molt records of spiders collected from the Cincinnati Nature Center as part of ongoing research from 2001 to 2023 were evaluated. From each year, four dates were obtained: the dates when the first male and first female matured, and the dates when half of the male and half of the female populations had matured. Growing degree days (GDD), a measure of heat accumulation, were calculated for each year prior to the start of maturation to determine the relationship between temperature and maturation rate. The results show a strong correlation between cumulative GDD and advanced maturation dates, with both male and female wolf spiders maturing 25 to 30 days earlier today than in 2001. These findings are clear evidence that rising temperatures are having a significant effect on the phenology of wolf spiders and underscore the importance of further investigation into the impacts of climate change on invertebrate populations around the world
