Recovery Of Degraded Lithium Ion Cathode Particles, James Kirtley

Undergraduate Research Conference at Missouri S&T

This project focuses on recovering the cathode materials of lithium ion batteries through atomic layer deposition (ALD) thin film coating. In industry, when a cathode material for a lithium ion battery are stored, it reacts with CO2 and moisture in the air creating Li2CO3 and LiOH on the particle surface. The harmful substances on the surfaces have a negative impact on battery performance and battery life. In this study, we found that when Li2Ni0.8Mn0.1Co0.1 (Ni-Rich NMC) is exposed to a high amount of moisture it degrades and the performance is reduced. For example, the discharge capacity of Degraded Ni-Rich NMC …

Co-Designing Ai Tools To Reduce Kidney Discard, Casey Hines

Undergraduate Research Conference at Missouri S&T

Currently, there are about 94,000 people on the kidney transplant waiting list. Less than one-third will receive a new kidney this year. Unfortunately, some kidneys that could have been transplanted into a new recipient, end up being discarded. The largest group of discarded kidneys are ones that are high-risk. At present, an organ procurement organization will send out offers for an available kidney to transplant centers. These offers go out in chronological order following the kidney transplant waiting list. A single high-risk kidney could potentially go through hundreds of offers before being accepted by a transplant center. The longer the …

Credibility And Divination In The Age Of Reason, Jessi Schoolcraft

Undergraduate Research Conference at Missouri S&T

Credibility is vital for comprehending the world around us. This is as true today as it was in the 18th century when Diderot and d'Alembert were producing France's first Encyclopédie. Translating articles from this body of knowledge provides insight into public perceptions of credibility. Designed to collect and share knowledge, the Encyclopédie required extensive collaboration among experts and editors. Article topics ranged from philosophy to the arts to physical science. What made these articles credible? Was it the oversight of well-known editors, the use of already verified sources, or the seal of approval from the State? Or was it a …

Fear To Cooperation: A Brief History Of The Space Race, Dylan Clay

Undergraduate Research Conference at Missouri S&T

In 1957, the United States and the Soviet Union engaged in a space race that, ironically, resulted in joint United States-Soviet Union missions with the 1975 Apollo-Soyuz program. Starting in the 1950s, the Cold War between the two nations led to a feeling of unease from the world populace, especially with uncertainty surrounding the superpowers' capabilities. In the late 1950s, the United States feared that they would lose the race to space because of Sputnik's success, but American efforts led to far greater success with American Astronauts landing on the moon, effectively ending the race to space. With both nations …

Mapping Renewal: How An Unexpected Interdisciplinary Collaboration Transformed A Digital Humanities Project, Elise Tanner, Geoffrey Joseph

Digital Initiatives Symposium

Funded by a National Endowment for Humanities (NEH) Humanities Collections and Reference Resources Foundations Grant, the UA Little Rock Center for Arkansas History and Culture’s “Mapping Renewal” pilot project focused on creating access to and providing spatial context to archival materials related to racial segregation and urban renewal in the city of Little Rock, Arkansas, from 1954-1989. An unplanned interdisciplinary collaboration with the UA Little Rock Arkansas Economic Development Institute (AEDI) has proven to be an invaluable partnership. One team member from each department will demonstrate the Mapping Renewal website and discuss how the collaborative process has changed and shaped …

Effects Of Sleep Deprivation On Learning In Fruit Flies, Natalie Gardner

Undergraduate Research Conference at Missouri S&T

The fruit fly Drosophila Melanogaster is an optimal research specimen when observing the effects of sleep deprivation on spatial learning. A fly's sleep can be tracked using locomotion while it is undisturbed and while it undergoes sleep deprivation. To measure a fly's visuospatial awareness, a region at a comfortable 24 degrees Celsius, among the rest of the arena yielding an uncomfortable temperature ranging from 36-37 degrees Celsius, is fit with a specific visual cue that the fly is able to identify. This region, along with it's visual cue, is rotated around the arena every 3 minutes, and the amount of …

Twitter Sentiment Analysis Of Major Us Topics, Arpan Das

Undergraduate Research Conference at Missouri S&T

The user base for social media platforms have seen sharp increases in nearly every year since their inception, to the point where it is a part of a daily routine in today’s society. Social media provides a powerful public platform for people to express their opinions and intentions regarding almost any topic. The objective of this study was to determine how the opinions of topics related to United States politics shift over the course of the election cycle and through the inauguration of the next president. These topics included the opinions of major events such as the major presidential candidates …

Realtime Sensor For Detecting Gallium Infiltration Attack, Peter Holtmann

Undergraduate Research Conference at Missouri S&T

The proposed research is to create a real-time sensor for detecting aluminum degradation due to gallium infiltration attacks, specifically in military vehicles and structures. Gallium acts as a poison to aluminum, leading to catastrophic failures of structural integrity. The proliferation of educational material on this subject raises security concerns for the United States Military, where nearly all structures utilize aluminum due to its high-strength, light-weight profile. Utilizing Fiber-Bragg Grating (FBG) sensors and machine learning techniques, this research aims to develop a real-time sensor to detect these attacks.

Behavioral Science Can Increase Zipper Merge Usage, Maria Galbraith

Undergraduate Research Conference at Missouri S&T

Research demonstrates that zipper merges (or late merges), under heavy traffic conditions, are safer and faster than a traditional early merge. In implementation, zipper merges can be less efficient due to a lack of compliance on the part of drivers, often more accustomed to early merging. Behavioral science has been applied to a many transportation-related challenges, such as increasing seat belt usage and decreasing drinking and driving but has not yet been applied to the zipper merge. We have identified six relevant behavioral science strategies including (1) social norms, (2) appeals to reason, (3) emotional appeals, (4) humor, (5) memory …

Thermal Modeling Of Li-Ion Batteries Using Sp+3d Model, Derrick Barger

Undergraduate Research Conference at Missouri S&T

An ideal battery model must gather sufficient electrochemical data about the system while remaining being computationally efficient. To prevent failure from thermal runaway, understanding the thermal characteristics of a battery is essential.

To achieve this, we have developed a single particle (SP) model, a simplified but accurate approach to battery modeling, and compared this to a previously designed 3D model. After validating the battery electrochemistry, equations were introduced to calculate the heat generation with a coupled 3D heat transfer component to provide data on the cell temperature. This same model was used to simulate a multi-cell pack.

The results indicate …

Simulation Of Optical Properties Of Dielectric Layers From Visible To Near Infrared Spectral Range, Andrew Cochran, Cory Conkel

ONU Student Research Colloquium

Optical properties of dielectrics play a critical role in various applications including the design and manufacture of optical components & devices such as detectors, filters, imagers, lenses, optical coatings, photonic crystals, sensors and waveguides, and solar cells. Radiative properties of varying thicknesses of different dielectrics such as Aluminum Oxide (Al2O3), Silicon Dioxide (SiO2), Indium Tin Oxide (ITO), Magnesium Fluoride (MgF2) and Silicon Nitride (Si3N4) have been simulated and compared in the range of visible to near infrared by mathematical modelling using MATLAB simulations. The results of the evolution of the radiative properties, as a function of dielectric material thickness, on …
