Spring 2010
Molecular dynamics simulation and density functional theory were applied to calculate heats of immersion (ΔHimm) of n-heptane, toluene, pyridine and water on two model sand surfaces and two model clay surfaces. Our results indicated that water showed the highest ΔHimm for the model clay surfaces...

Tungsten carbide-based metal matrix composite coatings are deposited by PTAW (Plasma Transferred Arc Welding) on production critical components in oil sands mining. Homogeneous distribution of the reinforcement particles is desirable for optimal wear resistance in order to reduce unplanned...

Fall 2011
Various pressures of compressed air were introduced into the flame spraying torch and the protective coatings of nanostructured and conventional titania (TiO2) were deposited on low carbon steel substrates. Performance of the coatings was studied using scanning electron microscopy (SEM), hardness...

Productivity and carbon accumulation potential of transferred biofilms in reclaimed oil sands-affected wetlands
DownloadSpring 2011
Biofilms are significant contributors to primary production, nutrient cycling, bio-stabilization and the food web of wetland ecosystems. Photoautotrophic biomass (PB) and primary production (PP) were determined for biofilms exposed to various treatments and materials in wetlands near Fort...

Fall 2011
One of the major issues in the current oil sands waste management techniques is a lack of a direct linkage between the long-term mine plans and the quantity of the tailings produced downstream. This research is focused on developing a linkage between oil sands long-term mine plans and the final...

Spring 2011
Flotation process is mineral processing technique used for separating valuable minerals from the gangue. The research presented in this thesis deals with assessing features that can help in measuring the performance (observing) bitumen flotation process and modeling damage in flotation units. A...

Tarring the Oil Sands: The Evolution and Emergence of ENGO Opposition in Alberta’s Oil Sands and Social Movement Theory
DownloadFall 2012
ABSTRACT: The Alberta oil sands represent tremendous economic growth and prosperity for Alberta and Canada but their development does not come without cost. Environmental Non-Governmental Organizations (ENGOs), specifically the Pembina Institute and Greenpeace, have brought significant attention...

Studies on the improvement in wear resistance of WC-Co composites by adding a pseudo-elastic TiNi phase and relevant issues
DownloadSpring 2012
In this study, pseudo-elastic TiNi alloy was added as a second phase to the Co matrix of WC-Co composite, which has found many applications in forms of coating, hardfacing overlay and bulk against wear. It was demonstrated that the added TiNi phase markedly enhanced the wear resistance of...

Fall 2013
This thesis is a multi-modal exploration of the photographer-researcher as a methodological opportunity to gain multiple, collaborative and collective perspectives on living in relation to the Alberta oil sands zone of North America. Using participatory-photography with youth, this thesis is one...

Removal of Organic and Inorganic Contaminants from Oil Sands Tailings using Carbon Based Adsorbents and Native Sediment
DownloadFall 2013
The extraction and refinement of oil sands bitumen produces substantial quantities of liquid tailings and solid coke. Tailings contain metals and naphthenic acids, which require remediation before mine closure. Adsorption is a potential remediation technique which may reuse stockpiled petroleum...
