Fall 2019
Interfacial activity of SAGD PW endogenous surfactants, humic acids (HAs), and their interaction dynamics with naphtha-diluted Alberta oil sand bitumen (AOSB) present in model SAGD produced water has been addressed in the first part of this PhD thesis. Dynamic interfacial tension σ(t) between oil...

Metal-Insulator Transition and IR Detection of Thin Films Fabricated by Pulsed Laser Deposition
DownloadFall 2018
Current thin film technologies and devices require high quality deposits in order to fully extract the potential of the material. Pulsed laser deposition (PLD) is one physical vapour deposition method used to synthesize these high quality complex films. PLD offers the distinct advantage of being...

Spring 2018
Developing miniature instrumentation for biosensing has attracted an extensive interest due to the demand for selective and sensitive detection of multiple targets at extremely low concentrations with exceedingly small sample volumes. Micro/nano mechanical sensors, such as microcantilevers (MCL),...

The Role of Sulfur Species in Establishing the Corrosion Reactions in Refinery Metallurgies
DownloadSpring 2016
This thesis is focused on the studying the role that model sulfur-containing molecules have in corrosion reactions on relevant metallurgies. This was done by using a design of experiments where a number of sulfur-based compounds were reacted with various metallurgies. The 8 model sulfur compounds...

Accelerated Dewatering and Drying Treatment of Oil Sands Tailings by Electrical Resonant Auto-Transformer
DownloadFall 2014
Canada has world’s third largest oil reserves in the form of oil sands and 20% of those are easily accessible by surface mining. The hot water bitumen extraction process has been used since 1967 and the process produces vast amount of tailings which are stored in ponds. Tailings ponds pose a...

Toward Direct Thermal-to-Electric Conversion: On-chip Microreactors for Catalytic Combustion of Methanol-Air Mixture
DownloadFall 2014
In this thesis, on-chip microreactors for catalytic combustion of methanol-air mixture were designed, fabricated and characterized. Using standard optical lithography, deep reactive-ion etching (DRIE) and other fabrication techniques, microreactors with integrated micropillars having four...
