An Exploration Of Simple Methods For The Purification And Separation Of Natural Curcuminoids, Eion S. Hinkle Apr 2025

An Exploration Of Simple Methods For The Purification And Separation Of Natural Curcuminoids, Eion S. Hinkle

Research & Creative Achievement Day

The separation of curcumin from other naturally occurring curcuminoids, such as demethoxycurcumin and bisdemethoxycurcumin, presents significant challenges due to their similar chemical structures. Conventional methods like column chromatography are energetically and environmentally costly, requiring large amounts of solvents and extended processing times. Alternatively, preparatory scale high-performance liquid chromatography (HPLC) offers high precision but necessitates expensive equipment, making it less accessible for routine laboratory use. This research explores simpler and more sustainable approaches to purify curcumin, aiming to reduce both the environmental impact and the financial burden associated with traditional separation techniques.

A Novel Fixture Development To Characterize Compression After Impact Damage Of Unidirectional Thermoplastic Composite Laminates, Matt K. Ficker, Dominic L. Perez, Noah Misukanis, Luke E. Poglayen, Jacob Kosmoski Apr 2025

A Novel Fixture Development To Characterize Compression After Impact Damage Of Unidirectional Thermoplastic Composite Laminates, Matt K. Ficker, Dominic L. Perez, Noah Misukanis, Luke E. Poglayen, Jacob Kosmoski

Research & Creative Achievement Day

Impact testing of unidirectional thermoplastic composite materials is a challenge due to the Mode I shear of the primary tows on the impact side. Thermoplastic composite products manufactured using laminate stacking are bonded together with films of polymer on both sides of oriented fiber in typically a cross-ply or quasi-isotropic stack. The resulting failure from the distortion field imposed by a hemispherical tup is debonding along the interface between layer 1 and layer 2 oriented in the layer 1 direction from impact site to edge of panel. This failure mode results when the sample is too small relative to the …

Relaxed Or Energized: The Impact Of Virtual Tourism On Emotions, Natalia C. Miller, Grace M. Baden, Samanth R. Dischinger Apr 2025

Relaxed Or Energized: The Impact Of Virtual Tourism On Emotions, Natalia C. Miller, Grace M. Baden, Samanth R. Dischinger

Research & Creative Achievement Day

With the growing accessibility of virtual reality (VR) and digital tourism, understanding its impact on emotional well-being is essential. This study explores the psychological effects of virtual tourism by examining whether participants feel more relaxed or energized after experiencing a virtual tour. The research involves participants engaging in a guided virtual tour of a destination, either with a VR headset or a tablet PC, followed by self-reported assessments measuring their emotions. There will also be a follow-up survey with open-ended questions asking participants to explain their responses to the previous survey. Data collection has been ongoing since March 2025. Any …

Impact Of Containerization On The Performance Web Applications With Docker, Amin Elkhalifa Apr 2025

Impact Of Containerization On The Performance Web Applications With Docker, Amin Elkhalifa

Research & Creative Achievement Day

This study aims to evaluate the performance impact of running a web application as a Docker container compared to running it natively. As Docker gains popularity in industry, it becomes increasingly important to understand the performance impact of containerization. This study aims to provide data that contributes to the decision-making process of building performance-sensitive applications. Gathering data consisted of building a web application, exposing an API endpoint, running tests and measuring the relevant performance metrics – CPU utilization and network response time – both in a native environment and within a Docker container. These findings confirm the introduction of overhead …

Using Multilayer Perceptron (Mlp) To Predict Crop Yields, Thomas M. Donnelly Apr 2025

Using Multilayer Perceptron (Mlp) To Predict Crop Yields, Thomas M. Donnelly

Research & Creative Achievement Day

This study aimed to develop a Multilayer Perceptron (MLP) that accurately predicts crop yields within 10% of ground truth in 80% of cases using weather data, region, soil type, temperature, fertilizer, irrigation, days taken to harvest, and rail fall. The dataset has 1 million unique data points and 10 columns. In order to process the data, all Boolean data had to be converted to integers, Numerical data standardized, while Categorical data was checked for non-null values. The model will be trained using a random selection of 90% of the data for training and 10% for testing. The effectiveness of the …

Using Fluorimetry And Colorimetry For Quantitative Analysis For Biomaterial-Derived Carbon Dots, Kahun N. Vue Apr 2025

Using Fluorimetry And Colorimetry For Quantitative Analysis For Biomaterial-Derived Carbon Dots, Kahun N. Vue

Research & Creative Achievement Day

The pursuit of sustainability in nanomaterial synthesis has led to the exploration of biomaterial-derived carbon dots (CDs) as an eco-friendly alternative to conventional methods. This study investigates the synthesis, characterization, and application of CDs derived from various biomaterials, including shrimp shells, food waste, cellulose, keratin, and saccharides. By employing hydrothermal, microwave, and ultrasound-assisted synthesis techniques, this research aims to develop a green, cost-effective approach to producing CDs while reducing environmental impact.

Previous work used shrimp shells as a starting material for a green CD. This work starts with shrimp shells to ensure reproducibility. In the future, novel materials like food …
