The Trials And Tribulations Of Building An Ebike From Recycled Parts, Olivia Conrady

Senior Honors Projects

The United States is far from being “walkable” in most suburban areas. Though public transportation has grown in its infrastructure in some large cities, it is far from sufficient. As a result of this, millions of people drive their cars every single day -- a practice that is unsustainable and becoming an increasingly evident issue. One possible solution that has become popular is the use of electric bicycles, since they are less physically taxing than a normal bike and allow for quicker transport. Though electric bicycles have been on the rise, they are still well outside of many people’s budget, …

Development And Characterization Of Quercetin-Loaded Microparticles Via Spray Drying For Pulmonary Drug Delivery Applications, Daniel Jose Perez Torres, Samantha Ann Meenach

Understanding The Role Of Sabp2-Interacting Proteins Sip432: A Premnaspirodiene Oxygenase Enzyme In Stress Signaling, Cristiana F. Martinez

Undergraduate Honors Theses

This study focuses on the characterization of a SABP2-interacting protein (SIP)-432. SIP432 is a putative premnaspirodiene oxygenase-like P450 enzyme. Premnaspirodiene is a 15-carbon compound that can be converted into antimicrobial compounds by a hydroxylation reaction. The interaction of SIP432 with SABP2, a critical component of salicylic acid-mediated plant immunity, implies a role for SIP432 in plant stress signaling. This study uses the T-DNA knockout mutant of Arabidopsis thaliana SIP432 (homolog of NtSIP432) to help understand its role in abiotic and biotic stress responses. Plants were subjected to abiotic and biotic stress to understand their role in stress response pathways. Gene …

Dewatering Of Chlorella Algae Using Co2 Gas Hydrate Formation For The Biofuel Production, Sumeet Oak

Master's Theses

When microalgae are processed for producing biofuel, dewatering the algae is an important step, particularly when combined with extracting valuable byproducts like algal oil. Conventional methods like centrifugation and filtration can be harsh on the algae and usually need high-energy inputs. In this work, the new application of CO2 gas hydrates as an algae dewatering agent was investigated. A CO₂ hydrate, CO2-nH2O, where n (n>5.75), is a nonstoichiometric compound where water molecules with hydrogen bonds are structured in an ice-like fashion to form polyhedral cavities. CO₂ gas hydrates are crystalline because gas molecules are trapped in a lattice of …

A Simplified Thermal And Battery Model For Off-Grid Solar Air Conditioning In Florida’S Hurricane Context, Steven A. Sanford

Honors Theses

Florida’s hurricane-prone climate often leaves residents without power and at risk of dangerous indoor heat conditions. This thesis examines whether an off-grid, solar-powered air conditioning system can feasibly maintain safe indoor temperatures over a one-week outage period during peak hurricane season. A simplified, lumped-capacitance thermal model and an energy-based (Coulomb-counting) battery state of charge (SoC) approach were developed in MATLAB to simulate a DC-powered air conditioner (the DC48 unit) in a single-zone space. Historical weather and solar irradiance data from Vero Beach, Florida, represent the hot and humid conditions typical of post-hurricane scenarios. The model uses an on/off plus deadband …

Biomimetic Design Of Mechanochromic Single-Chain Nanoparticle Polymer Networks, Samuel Robinson

Honors Theses

Hydrogels are a class of polymer networks that show promise in many biomedical applications but are typically limited in use due to their brittle nature. Synthesizing hydrogel networks that are comparable to biological materials has long been an area of interest. In this study, we are working to create a polymer network inspired by the muscular protein, titin. Titin can unfold under mechanical tension, releasing stored length, making the muscle material extensible and durable. To mimic this behavior, we propose creating a polymer network with similar stored length using single chain nanoparticles (SCNPs) cross-linked with phenolphthalein (PP) and β-cyclodextrin (β-CD). …

Particle Deflection In A Macroscale Ultrasonic Angled Wave Device, Nicholas Rivet, Bart Lipkens, Walter Presz

Student Work - College of Engineering

Macroscale bulk ultrasonic standing waves oriented at an angle relative to a fluid velocity field offer a method for sensitive particle separation. We have previously reported on the theoretical development of such a system (Proceedings of Meetings on Acoustics Vol. 30, 045004 (2017), https:// doi.org/10.1121/2.0000652). Particle deflection is uniquely defined by two parameters, i.e., the non- dimensional ratio of the acoustic radiation force to the fluid drag force exerted on the particle and the angle of the standing wave with respect to the fluid velocity. Here, we highlight the development and testing of a thirty-degree acoustofluidic angled wave device with …
