Spring 2014
Energy harvesting is an important developing field in Microelectromechanical Systems (MEMS) research. In this thesis, a fixed-fixed folded spring-based harvester is presented as an alternative mechanical element for beam-based piezoelectric harvesters to reduce its natural frequency for low...

High pressure carbon dioxide adsorption processes are employed in applications such as carbon dioxide capture and supercritical fluid chromatography (SFC). Carbon dioxide capture using adsorption has gained wide attention because of the promising materials that are developed for this application....

An Investigation of Using n-Si Piezoresistive Behavior to Develop a Three-Dimensional Stress Sensing Rosette
DownloadFall 2013
This work involves the design, microfabrication, calibration, and testing of a new silicon-based piezoresistive rosette capable of extracting the three-dimensional (3D) stresses in the silicon upon deformation. A new 10-element piezoresistive rosette was devised to extract all stress components...

Antimicrobial applications of treatments using light pulses emitted from light emitting diodes (LED)
DownloadSpring 2022
Low water activity (aw) foods have been associated with several foodborne outbreaks and recalls. Eradication of foodborne microorganisms like Salmonella and Escherichia coli from low aw foods is challenging, as they are resistant to conventional decontamination practices. High intensity light...

Beyond Viscosity—How Density, Vibration and Interfacial Tension Affect Solvent Aided Bitumen Production
DownloadFall 2016
Bitumen and heavy oil comprise a significant percentage of proven oil reserves globally. The environmental impacts of producing these resources with current technologies is a concern for environmentalists, oil producing companies, resource rich jurisdictions and society at large. Dilution of the...

Pseudomonas aeruginosa is an opportunistic pathogen that forms chronic biofilm infections in the lungs of cystic fibrosis patients. A major component of the biofilm during these infections is the exopolysaccharide alginate, which is synthesized at the inner membrane as a homopolymer of 1–4-linked...

We study the evolution of chaotic mixing in an initially stratified circular vessel. The bottom and top halves of the vessel are filled with viscoplastic and Newtonian fluids. A circular stirrer in the vessel promotes the mixing. We considered three different viscosity ratios to understand the...
