Development of an Electronic Nose for Detection of Volatile Organic Compounds Based on Nanoporous Microcantilevers by Using Photothermal Spectroscopy
DownloadSpring 2015
An electronic nose for identification and quantification of volatile organic compounds (VOCs) mixtures was developed using a nanopore-enhanced photothermal cantilever deflection spectroscopy (PCDS). PCDS provides highly selective detection of vapor mixtures of VOCs from specific molecular...

Crude oils contain a distribution of molecules with diverse chemical structures and molecular weights. Asphaltenes are considered the most problematic of these structures. We have investigated the adsorption and aggregation of asphaltenes on surfaces using scanning probe microscopy. Modifying the...

Spring 2017
One of the central puzzles concerning the interaction of low Reynolds number (Re<<1) fluid transport with bacterial biomass is the formation of filamentous structures called bacterial streamer. Bacterial streamers can be tethered at one or both ends to solid surfaces, while the rest of the...

Novel Plasma Based Technology for Treatment of Emerging Contaminants in Water: Understanding Physiochemical Processes and Applications
DownloadSpring 2017
Indiscriminate and widespread disposal of pharmaceutical compounds, dye molecules, and pesticides in to water resources pose a serious threat to the quality of drinking water. A critical need exists for developing novel practical, efficient, and cost effective water treatments for remediation of...

Conduction and Dielectric Relaxation Mechanisms in Oil Sands Influencing Electrical Heating
DownloadFall 2016
Electrical heating has been proposed in the past as an alternative to conventional water based thermal methods for reducing viscosity of bitumen in oil sands reservoirs. This could reduce or even eliminate water use and associated problems like inefficient heat transfer in the reservoir, poor...

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...
