In 1932, coal miners inside of Alberta's Crowsnest Pass struck for 195 days over working conditions. I use a multi-perspective approach and found my analysis on the basis of community to increase our understanding on industrial disputes. I explore the strike from the viewpoint of coal operators,...

A major challenge to any “solvent-based” bitumen extraction technology is the removal of suspended fine solids from the hydrocarbon medium (i.e. diluted bitumen). To address this problem, we examined how colloidal solids could be made to aggregate in a hydrocarbon medium and thus be separated by...

Poor settling of solids increases land requirement for tailings containment and imposes severe constraints on the water balance. Consequent to these considerations, the alternating current electrocoagulation (AC/EC) technique emerged as a candidate for enhancing the settling behaviour of...

In the development of a numerical model for the water cycle on Mars, adsorption of water vapour in the Martian regolith acts as a significant sink and retards the transport of mass. Adsorption on Mars cannot be studied directly, so a numerical model was created, and a diffusion sorption...

Atomistic Approach towards Sodium Citrate Role on Surface Properties of Silica and Clay Minerals
DownloadFall 2022
The use of sodium citrate as a secondary processing aid in combination with caustic significantly improved bitumen recovery, specifically in poor oil sands ores. The role of sodium citrate on wettability alteration of solid surfaces, benefiting bitumen liberation as well as improving bitumen...

Interactions of finely dispersed abrasive particles in chemical mechanical planarization (CMP) slurries play a vital role in determining the polishing performance. In this study, coupled influence of hydrodynamic and colloidal interactions on the attachment of nanosized ceria (CeO2) particles to...

The removal of solid particulates from crude oils and hydrocarbon streams is a common challenge in refining. Finding a method for efficient removal of the suspended solids in the oil streams is the main objective of this work. Paraffinic and aqueous treatment and the combination of these two...

Nonlinear optical techniques are widely used for surface analysis, as they are surface specific and can be used to probe interfaces of insulators such as silica. Silica is commonly found in nature such as reservoirs of natural water and oils. Nonetheless, it is not clear how silica interacts with...

Studying the Molecular Structure of Aqueous/Mineral Oxide Interfaces by Vibrational Sum Frequency Generation Spectroscopy and Zeta Potential Measurements
DownloadFall 2021
Water/mineral oxide interfaces are ubiquitous in various atmospheric, geological, biological, and industrial systems. Hence, studying such abundant interfaces is essential for understanding the macroscopic interfacial reactions, such as adsorption/desorption, dissolution, flocculation,...
