Carbohydrate-Modified Microgels as a System for Extracting Naphthenic Acids from Tailings Pond Water
DownloadFall 2015
Northern Alberta houses massive tailings ponds, that store aqueous waste as a result of the processes employed to recover bitumen from the oil sand deposits. The aqueous waste, or tailings pond water (TPW), houses numerous toxic chemicals including naphthenic acids (NAs) - a complex group of...

Functionalized Thermo-responsive Polymer Core-shell Materials for use in Controlled Dye Release, Thin-film Composite Membranes, and Water Desalination
DownloadSpring 2024
This thesis focuses on the varied applications of core-shell structured stimuli- responsive polymer materials and their applications in water treatment. The relevant background and introduction to stimuli-responsive polymers, core-shell particles and morphologies, and membrane separations systems...

Stimuli-Responsive Microgel-Based Materials and Their Assembly for Controlled Drug Delivery and Sensing Systems
DownloadFall 2020
Conventional drug delivery methods result in a burst of drug concentration in plasma, followed by a decline, which leads to issues with maintaining drug concentrations in the therapeutic range. Furthermore, this high plasma concentration can lead to undesirable (and dangerous) side effects that...

Stimuli-Responsive Polymer-Based Materials and Devices for Controlled and Triggered Release of Small Molecules
DownloadSpring 2020
This thesis covers the general scope of stimuli-responsive polymers and the concept of controlled drug delivery, with special focus on controlled/triggered release applications of temperature-responsive poly (N-isopropylacrylamide) (pNIPAm)-based hydrogels, microgels, their assemblies, and...

Towards a Better Understanding of Poly(N-isopropylacrylamide) Microgel-Based Etalons and their Continued Development in Diagnostics
DownloadFall 2013
Poly(N-isopropylacrylamide) (pNIPAm) microgel-based etalons are photonic materials that exhibit color based on temperature or other environmental stimuli. These materials provide a new and unique method for biosensing and other applications. Therefore it is important to understand these materials...
