This study aims to educate participants about the formation and significance of grain structures in metals, focusing on the processes by which grains form and how these structures influence material properties. Using 1018 steel (low-carbon), 1045 steel (medium-carbon), 1080 steel (medium-carbon), ductile and grey cast iron, and PbSn (lead-tin) samples, 18 teams explored the random formation of grain structures through a series of preparatory steps, including mounting, grinding, polishing, etching, and hardness testing. Each team examined their samples at four magnifications to identify microstructural features and measure grain size using two different methods. In addition to the technical analysis, the teams focused on uncovering the artistic patterns that emerge from the randomness of grain formation. The study will highlight the art found in these naturally occurring structures, demonstrating how materials science and art intersect. By the end, participants gain an understanding of grain theory and microstructural analysis while also developing an appreciation for the unexpected artistic forms created by these random processes in materials like steel, cast iron, and lead-tin alloys.

Microclimates, which refer to the localized atmospheric conditions within small-scale environments, can be influenced by a variety of factors such as vegetation, topography, and human activity. One of the key elements that affect microclimates is the type of canopy cover present in an area. Open areas, where there is little vegetation and more exposure to the elements, often experience different conditions compared to areas with dense canopy cover, where the vegetation provides more shelter and shade. Understanding the differences in microclimatic conditions between these two types of environments helps us understand how these environmental conditions affect people, plants, and animals. The purpose of this study is to explore how microclimates vary between open areas and areas with closed canopy cover, focusing on factors such as temperature, humidity, and NDVI to better understand how canopy cover influences environmental conditions.

Examining the Relationship Between Tree Canopy Cover and Walkability in Austin, Texas

Type: Undergraduate
Author(s): Zoey Suasnovar Environmental Sciences
Advisor(s): Brendan Lavy Environmental Sciences

Cities are increasingly adopting and promoting actions in support of their sustainability goals to enhance community well being and improve environmental quality. These large, sprawling cities actions include providing more sustainable transportation choices, like bike lanes, micro-mobility options (e.g., scooters or e-bikes), and walkability. Yet, as municipalities offer these alternatives, increasing urban heat may deter residents and visitors from using them. Cities, such as Austin, Texas, have become hotter over the last decade due to increasing impervious cover and tree loss associated with urban (re)development. Urban trees provide cooling effects to the surrounding area through evapotranspiration and shade. Thus, tree shade is important to promote more walkable neighborhoods, especially in the summer months. This study looks at the relationship between canopy cover and urban walkability in Austin. Using a Geographic Information System, we examined the interactions between canopy cover, walkability, socioeconomic data (i.e., race, gender, income, and home-owner status), and sidewalks. In doing so, we found a total of 2,552.47 km of shaded sidewalks, equaling, about a third of all sidewalks in Austin. We also found that canopy cover and walkability vary by location. Some areas have high canopy cover and low walkability, whereas other areas have low canopy cover and high walkability. Preliminary results also indicate that some areas have less shaded sidewalks than others and vary based on an area’s socioeconomic characteristics. The results of this research may be used to promote sustainable cities and urban forestry along sidewalks to help mitigate the urban heat island effect.

Increases in city size and frequency have correspondingly led to increases in Urban Heat Island (UHI) strength and frequency. These urban heat islands have had serious implications for both children’s health and education. One widely accepted UHI mitigation strategy is green spaces. However, these have mainly been studied in the context of parks. This study aims to fill in a necessary gap of knowledge by studying the effect of green spaces at elementary schools. This was done by looking at the percentage of tree coverage at 273 public elementary schools in Tarrant County and comparing them to the Land Surface Temperatures (LSTs) of those schools. Google Earth Engine, ArcGIS Pro, and Google Spreadsheets were the three main software systems used to accomplish this. This study found that the percentage canopy cover and LST were inversely proportional at elementary schools in Tarrant County. It also found that other factors apart from trees effect LST.

With only four species of fish collected in the Dallas Fort Worth Metroplex as recently as the 1970’s, it is no surprise that the Trinity River was once referred to as the “mythological river of death”. Since then, coordinated improvements in water quality have led to the recovery of fish assemblages within the Trinity, becoming a well-documented environmental success story. To monitor that recovery, the Trinity River Authority has conducted Aquatic Life Monitoring surveys on one or more Trinity Basin waterbodies biannually since 2013. These surveys have targeted waterbodies with documented concerns or impairments for one or more water quality parameters, capturing conditions in both the Index (March 15-Oct 15) and Critical (July 1-Sept 30) periods. At each site, whole community fish data was collected via backpack electroshocking and seine netting, alongside benthic macroinvertebrate and habitat data. As of 2025, 30 surveys have been conducted on 13 waterbodies throughout the Upper Trinity basin. Although these surveys have targeted streams with water quality concerns, 90% of sites have scored as either High or Exceptional on the State of Texas Regionalized Nekton Index of Biotic Integrity. Here we will characterize the collected fish communities with over 12,500 individuals from 41 unique species collected during these surveys, while also describing the vision of the program over the next decade.

Location: SecondFloor, Table 3, Position 2, 1:45-3:45

Prior to 2019, Texas used red-light traffic cameras to deter drivers from driving recklessly and running red lights. However, due to legislation signed by Governor Greg Abbott, red-light cameras are no longer used in Texas. This decision was made to ‘protect drivers' constitutional rights.’ Additionally, it was argued that these cameras increased the rate of rear-end collisions.

This study investigates the effect of removing red-light cameras in Fort Worth before and after the ban by examining the rate of different types of collisions. The location data of crash sites and police reports will be mapped using ArcGIS Pro to determine the frequency and density of these crashes.

Amazon Deforestation: A Spatial Analysis of Its Impact on Carbon Sequestration and Global CO2 Emissions

Location: FirstFloor, Table 2, Position 1, 11:30-1:30

The Amazon rainforest is one of the largest carbon sinks in the world, playing a critical role in regulating global carbon dioxide levels. However, deforestation has significantly reduced its ability to sequester carbon, contributing to rising CO2 emissions. We will analyze deforestation trends in the amazon over the last three decades by integrating satellite imagery, historical land cover data, and carbon flux models. Using remote sensing data from Nasa and Brazil’s National Institute for Space Research (INPE), we will generate temporal GIS layers to map forest loss and quantify the impact on carbon sequestration. Through identifying key deforestation hotspots, this project aims to provide important insights into the relationship between land-use changes and atmospheric carbon levels, supporting future conservation strategies and policy recommendations.

Tri-colored bats are on track to be listed as an endangered species, however insufficient information is available on their roost sites. The aim of this project is to determine which culverts in Texas, more specifically Tarrant County, are likely to be used as winter roosts for the Tri-colored bat species. The project will utilize available culvert data from TxDOT and data on the potential ranges of Tri-colored bats. Analysis will begin by categorizing the culverts into individual layers by features such as height, length, and material.

Exploring Levee Systems of the DeGrey River: Geomorphological and Reservoir Potential

The ephemeral DeGrey River of northwestern Australia’s Pilbara region presents unusual very high relief double levees of up to 5.8 m that are still poorly understood. This study aims to take advantage of excellent exposures of these double levees to assess their likely origin. Accessing and studying these features in a modern setting constitute a unique opportunity to better understand their geomorphology and evaluate their reservoir potential as an analogue for the subsurface.
We investigated these levees using shallow augering, percussion coring, digging of shallow pits, and ground-penetrating radar (GPR), calibrated using dGPS surveys. Remote sensing data, such as LIDAR and photogrammetric drone surveys, were also used to identify and visualize fluvial geomorphologic features, which were then ground truth by pedestrian surveys and general field observations. Core and auger samples were described according to grain texture using the USDA classification and a Munsell color atlas. to distinguish the similarities or differences from sediments by depth. Grain size was further assessed in sand and gravel using a Brunton Grain Size Card.
These levees were primarily developed by water during multiple large flooding events which exceeded their height limit, as opposed to the alternative hypothesis that these were large eolian features coincidental with levee positions at the channel margin. This is evidenced by the common layers of gravelly and poorly sorted coarse sand dispersed within the levee strata. Similarly, sedimentary structures of lower and upper flow regimes typical of water flood are observed for these strata. Locally, the outer part of the two levees was found to include an eolian cap, which provided additional height to the levee locally. These strata were fine-grained and well-sorted by contrast, typical of aeolian origins.
Cyclone-driven floods control the activation of the DeGrey River and associated sedimentation. These double levees form through rapid sediment deposition in unusually energetic overbank flows. The high permeability and sandy stratification of these levees provide opportunistic reservoir potential. This contrasts with silty levee deposits observed in perennial rivers with lower discharge variation. The high double levees of the DeGrey River appear to be a hydrologic and geomorphic feature characteristic of ephemeral river systems.

Location: Third Floor, Table 7, Position 1, 1:45-3:45

This study aims to use chemodynamics to engage the interplay between societal actions and environmental response. The project will build upon data from thermogravimetric and isotopic analysis capturing macroscopic soil chemodynamics in response to suburbanization in the Dallas-Fort Worth Metroplex (DFW). The DFW is one of the fastest growing metro areas in the US. Our early data suggests that a minimum of 30-yrs is the required period of lawn care before key chemodynamic indicators of soil health/resilience, such as R50 and isotope 13C (quantity and quality, is needed for lawns to return to their pre-suburbanization environmental status.

The objective is to examine implications at the microphysical and molecular-level via: Assessing how differences in the molecular composition of soil organic matter from a suburban lawn changes over time.

The purpose of this project is to determine if California's raging wildfires are having a detrimental effect on the state’s tree populations/health. Two main components of this project would be, a model of California's tree density/canopy cover in 1990, and a model of California’s tree density/canopy cover in 2020. The goal of this project is to determine if an increase in wildfires is a key factor in the decrease of California tree density, and if so, make recommendations for further research on how to protect trees from this natural disaster.

A Study of Fossilized Root Colonies as Indicators of Past Water Table Levels in the Coll De Montllobar

Type: Undergraduate
Author(s): Daphne Varmah Geological Sciences
Advisor(s): John Holbrook Geological Sciences
Location: Basement, Table 2, Position 1, 1:45-3:45

The Coll de Montllobar cliffs in the Pyrenees Mountains contain plant fossils known as root models, which show signs of oxidation and reduction along a depositional dip, indicating varying environmental conditions Since plant roots do not grow below standing water levels, these fossilized roots and their distribution can serve as markers for past water table positions. This study examines whether root density decreases toward the bottom of the channels, indicating that roots stopped growing once they reached below the water table. If the roots disappear at a certain depth, it suggests that the bar was saturated at that level, stopping root growth. By analyzing the presence and absence of these roots, we aim to determine if they mark a clear boundary indicating historical water table levels. Our findings contribute to understanding past depositional environments and hydrological conditions in this region

The Barnett Shale formation in the Fort Worth Basin has been a substantial producer of oil and gas energy resources. The Barnett Shale serves as an ideal testing ground for innovative approaches to subsurface analysis, offering both abundant production history and a wealth of existing data. This study integrates innovative thermal analysis techniques with AI-driven workflows to rapidly process and interpret large volumes of geochemical data. We aim to identify and evaluate geochemical variability and the distribution, content, and quality of geogenic carbon with depth across key stratigraphic intervals. Expanding subsurface applications of AI and machine learning enhances the scalability of resource assessments and underscores the broader potential of these emerging analytical tools in energy exploration.

Predicting Pesticide Degradation: A Molecular Scaffolding Approach to Environmental Hazards

Type: Undergraduate
Author(s): Christopher Zamora Geological Sciences
Advisor(s): Omar Harvey Geological Sciences
Location: Basement, Table 5, Position 3, 1:45-3:45

Pesticide degradation in the environment is an important element when it comes to understanding long-term soil and water contamination. There are many key molecular factors like molecular weight and octanol-water partitioning (logP) that influence how pesticide degradation works. By taking a computational approach, we derived daughter molecules of ferulic acid, 1,2,4-Trihydroxybenzene, and vanillic acid which share similarities with pesticide byproducts. We specifically computed molecular weight and logP for each derivative to assess their potential to contaminate the environment. By comparing these values to oxidative pesticide breakdown products from glyphosate (Roundup), atrazine, and chlorpyrifos, we identified solubility trends that may influence the transport of these molecules into soils and water systems. These findings provide insight into the environmental risks associated with pesticide use and degradation, potentially aiding in the design of more sustainable agricultural chemicals.

Artificial intelligence’s integration into healthcare promises more effective and higher-quality patient care. However, its impact on the human aspects of care, such as trust and bias, remains not fully understood. Through a literature review and analysis, this poster provides an up-to-date overview of how the implementation of AI affects patient-provider interactions. This research seeks to answer the question: “How does AI-driven diagnosis and treatment influence patient-provider interactions, and what role does AI bias play in shaping trust and healthcare disparities?” Our findings show a consensus that AI improves productivity, but there is concern that the public’s growing trust in AI over human providers may reshape relationships and perpetuate healthcare disparities. Understanding these dynamics is crucial for developing AI systems that enhance care while maintaining equity and trust in healthcare settings.

Location: FirstFloor, Table 3, Position 1, 1:45-3:45

At the heart of the Texas Christian University chemistry department, there are two main factors contributing to chemical education: professors and students. Our students are vitally important to the chemistry department as they not only receive education but are educators themselves. TCU chemistry club members serve as sources of experience, knowledge, and study skills, including those outside the context of chemistry. The challenge of chemical education is the “translation” of material to a diverse student body. What is special about these “student educators” however, is their ability to do so to individuals of all ages and all skill levels. The TCU chemistry department has many different teaching opportunities in both general and organic chemistry labs and lectures such as Teaching Assistants (TAs) and peer tutors. Of these positions, many are filled by the TCU chemistry club student body. Our Chemistry Club students go beyond the education of fellow undergraduates, as they educate students in the local elementary schools about science. Our Chemistry Club members have become well-rounded and effective educators through the variety of services provided to them such as, peer guides, university classes, and supportive professors. The Chemistry Club students provide knowledge of chemistry but they also encourage confidence, and serve as a source of mentorship in the Fort Worth community. At TCU we strive to not only learn but also share the wealth of wisdom gained during our time in the chemistry department at TCU.

Historically, students have envisioned scientists as white males in lab coats, reinforcing exclusionary stereotypes that can discourage diverse participation in STEM. Mentorship has the potential to broaden perspectives, enhance self-esteem, and support identity development, yet research on its specific impact in middle school remains limited. This study examines how a structured mentorship program influences middle school students’ perceptions of scientists and their own scientific identity, particularly in STEM and healthcare professions, asking: How does mentees’ identity in science and healthcare professions develop through interactions with mentors and peers? This qualitative study follows seven 7th- and 8th-grade students (ages 13–14) in a year-long mentorship program led by junior college undergraduates. The research employs a pre- and post-intervention assessment using the Draw-a-Scientist Test (DAST) alongside open discussions and interviews to evaluate shifts in students’ identity perceptions. DAST drawings are analyzed with a rubric evaluating gender, activity, location, and skin tone to identify shifts toward more inclusive representations. The study anticipates that students will depict more diverse scientists over time, moving beyond traditional stereotypes. Findings are expected to reveal more diverse depictions of scientists, offering insights into how mentorship fosters inclusivity and belonging in STEM for underrepresented middle schoolers.

Crafts and Conversations collaborates with Trinity Terrace and Brookdale assisted living facilities to foster a connection between TCU students and the residents living there. Through monthly meet ups with crafts and music, inter-generational relationships are built between students and residents. Crafts such as painting with mini easels or making yarn octopi provide a base talking point that expands into other natural parts of conversation, such as telling stories. Students that volunteer at crafts gain friendships, valuable interactions that combat stereotypes against the elderly, and improved communication skills. Additionally, students have the opportunity to perform music, enabling them to further expand their creativity. Residents at assisted living facilities also gain valuable friendships and interactions that combat the potential loneliness of at a retirement center. Crafts and Conversations strives to enrich the lives of all those involved through engaging activities that bring people closer together.

Health Screening Day: Improving Healthcare Access for Fort Worth Patients Experiencing Homelessness

Beautiful Feet Clinic, founded by Dr. David Capper, provides free medical, dental, and holistic care for individuals experiencing homelessness in Southside Fort Worth. One of the critical challenges faced by individuals experiencing homelessness is the lack of access to preventive screenings, flu vaccinations, and health education, leading to the late detection of chronic illnesses such as diabetes, hypertension, and cancer. Many patients at Beautiful Feet Clinic do not routinely engage in preventive care, as their immediate survival needs—such as securing food and shelter—often take precedence over long-term health maintenance. Without timely interventions, undiagnosed and unmanaged chronic illnesses contribute to higher emergency department utilization, increased morbidity, and worsening overall health outcomes.

To address this gap, we partnered with Lauren, a medical student at TCOM, to offer flu vaccinations and organize a Community Health Screening Day on March 29th, 2025, offering essential health screenings and practical nutrition education aimed at empowering individuals experiencing homelessness to improve chronic disease management and overall well-being. Patients will learn simple meal modifications to make healthier choices within their available food options through educational pamphlets with a focus on nutritional education to reduce chronic illnesses. The event also enhances medical student training, with efforts to secure an OB-GYN physician to guide manual breast exams and oversee preventive education regarding breast and skin cancer screenings. The initiative also administered 22 flu vaccinations to address gaps in preventive care, reducing the risk of seasonal influenza among unhoused individuals who face significant healthcare barriers. Additionally, in collaboration with Moncrief Cancer Institute, a mobile cancer screening clinic, we will provide free cancer screenings in summer 2025, to promote early detection for at-risk individuals.

Beyond medical care, Beautiful Feet Clinic also faces communication barriers with Spanish-speaking patients, limiting access to critical health services. Many patients and healthcare providers recognize the need for language accessibility and the importance of qualified interpreters in delivering effective care. To address this, we translated the clinic’s intake forms into Spanish and established a list of medical students proficient in Spanish who can assist with interpretation over the phone. This initiative enhances provider-patient communication, ensuring that Spanish-speaking individuals receive accurate medical information and compassionate care.

By integrating screenings, outreach, language accessibility, and hands-on clinical training, this initiative fosters health empowerment and long-term community-based healthcare solutions. It emphasizes collaboration between healthcare institutions, students, and local clinics to bridge gaps in care for vulnerable populations.

Geodesic Nets - Construction and Existence

Type: Undergraduate

Advisor(s): Ken Richardson Mathematics
Location: Basement, Table 10, Position 2, 1:45-3:45

Geodesic nets are types of graphs in Riemannian manifolds where each edge is a geodesic segment. One important object used in the construction of geodesic nets is a balanced vertex, where the sum of unit tangent vectors along adjacent edges is zero. We prove the existence of a balanced vertex of a triangle (with three unbalanced vertices) on a general two-dimensional Riemannian surface when all angles measure less than $2\pi/3$, if the length of the sides of the triangle is not too large. This property is a generalization for the existence of the Fermat point of a planar triangle.
