Pivot Irrigation Misalignment (PIMA) System Project

Pivot irrigation systems are typically a quarter mile long and rotate about a field to irrigate crops. Approximately every fifty meters, there are towers that help move the system. When a tower misaligns, either due to a flat tire or mechanical malfunction, the system’s safety procedure is enabled and shuts the entire system down. When

Development of MOF/Graphene Aerogel Composite for Ammonia Adsorption and Sensing

Metal-organic frameworks (MOFs) are a class of crystalline materials which have properties useful for gas separation, purification, and storage. While these MOFs can be extremely selective with the molecules they adsorb, the desorption processes can be slow and inconvenient. The objective of this project is to create and study a MOF/graphene aerogel composite which is

Benchmarking Dehumidifiers as Atmospheric Water Generators in Tempe, AZ

The goal was to benchmark the performance and quality of water collected from the air using common household dehumidifiers as atmospheric water generators. It is found that for between $13 and $20 a day, 12 to 19 gallons of clean water can be produced in a device that fits within a single square meter. Envisioned

Designing A Control System to Adjust Surface Roughness of an Airfoil

This research focused on investigating flow control using surface roughness along the leading edge of an airfoil. The current design will entail a system that can accurately predict flow separation on the upper surface. This is done by measuring the angle of attack and static pressure to determine flow separation. For future research this can

Removal of Hydrocarbons in Solar Drying System

The focus of this research is to provide a sustainable system to manage food production by developing a food preservation system. Drying removes moisture from food so unwanted contaminants can’t permeate into the food, causing it to spoil. Additionally, drying makes food smaller and lighter, making storage easier. Biogenic hydrocarbons are released in the drying

Nanoscale Material Characterization of Polymer Matrix Composites Under Hygrothermal Conditions

This experiment analyzed the structural capabilities of polymer matrix composite (PMC) samples after many years of exposure to hygrothermal conditioning. This strong, form-adaptive, lightweight material is suitable for use on critical structures including powerplants and spacecrafts, however, the degradation impacts from long-term exposure to heat and humidity is yet unverified. To study that phenomena, aged

Developing Poly-catechols using Engineered Strains of Ecoli

This project aims to develop a microbial approach to produce a variety of poly-catechols or bio-plastics using E.coli generated CotA laccase enzyme and to analyze the properties of these bio-plastics. The aromatic substrates will be processed through specific E.coli laccase enzymes and the polymer product will be analyzed with Gel permeation chromatography. Producing these alternate
