As the development, processing, and manufacturing of plastic has improved over the years, so has our amount of plastic waste. Currently, only approximately 9% of post-consumer plastics get recycled. The other 91% is buried in landfills, burned, ends up in the ocean, or is accumulating in communities without access to...
Menstrual health and hygiene insecurity is a global health issue people across the world face, particularly in developing countries. According to the World Bank, an estimated 500 million lack access to adequate menstrual products, and “to effectively manage their menstruation, women and girls require access to water, sanitation, and hygiene...
This thesis explores the mechanical properties of hemp fiber reinforced polylactic acid (PLA) composites. Fused filament fabrication (FFF) was used to compare the performance of three different weight percentages of hemp fiber reinforced PLA against PLA and acrylonitrile butadiene styrene (ABS). It was found that as the weight percentage of...
Post-Consumer Recycled (PCR) resin grades have been successfully incorporated into plastic ink supply cartridges, with 80% of cartridge products containing 45% to 70% recycled polyethylene terephthalate (rPET). With this tremendously successful experience, incorporation of recycled polypropylene (rPP) into Injection Stretch Blow Molding (ISBM) bottles has been attempted to increase sustainability...
Climate change is a pertinent issue causing an increase in the quantity and severity of wildfires. Current market solutions to protect homes from wildfires are expensive and do not always guarantee the safety of the home. Superabsorbent polymer (SAP) is a cross-linked polymer that can absorb over 100x its weight...

Tyrosine kinases mediate response of blood cells to stimuli and small molecule tyrosine kinase inhibitors (TKIs) serve important roles as drugs in managing hematological diseases. In healthy B cells, the B cell receptor (BCR) activates a tyrosine kinase known as Syk, which then activates BTK, PI3K, PLC2 and protein kinase...
The advent of 3D Printing has invigorated research into metamaterials, synthetic composite material that produce properties generally not found in natural materials, requiring further studies into understanding the fundamental properties of these materials. This dissertation proposes a novel imaging technique to investigate the surface interactions occurring in an unsaturated packed...
Silicon wafer cleaning is a ubiquitous unit operation in the semiconductor industry to remove excess material or nanoparticle impurities to obtain perfectly smooth and clean wafer surfaces. Extensive research has already been completed to understand the physics behind hydraulic jumps observed due to balance of forces when a coherent Newtonian...

Due to their viscoelastic properties, polymers and hydrogels are widely used in many applications. In this study, the viscoelastic properties of elastomer polymers were investigated for a series of hydrogel, hydrogel composites and silicon materials. A primary application for hydrogels and hydrogel composites is as a replacement for the degenerated...
The measurement of extensional viscosity is important in many chemical, biomedical, agricultural, and engineering applications. The determination of extensional viscosity is generally difficult, expensive, and inaccessible outside of research labs. The development of a smartphone application (app) that could use a phone’s high-speed camera to measure this parameter could open...
