Investigation of the Adsorption of Model and Oil Sands Process-Affected Water Naphthenic Acids on Graphite
DownloadSpring 2015
Naphthenic acids (NAs) are constituents of bitumen in the oil sands deposits in northern Alberta, Canada. The extraction process of bitumen creates an enormous amount of wastewater called oil sands process affected waters (OSPW). This OSPW contains elevated concentrations of NAs, and other...

Spring 2013
Coagulation/Flocculation/Sedimentation (CFS), petroleum coke (PC) adsorption, and zero valent iron (ZVI) oxidation-enhanced by PC were applied for the remediation of oil sands process-affected water (OPSW), generated from oil sands operations in northern Alberta, Canada. OSPW is a complex mixture...

Probing Surface Heterogeneity, Electrochemical Properties and Bubble-Solid Interaction Mechanisms of Sulfide Minerals in Flotation
DownloadSpring 2017
The colloidal stability governed by various surface interactions including van der Waals (VDW) interaction, electrical double layer (EDL) interaction, hydrophobic interaction, and some other interactions, plays an important role in a wide range of natural phenomena and engineering applications....

Graphite-forming events occurred throughout Earth history and extend up to solar and pre-solar contexts. However, a comprehensive understanding of the timeline of these events has been hindered by a lack of chronological information for graphite. Here we explore the geochronological potential of...

Protein folding involves a stochastic search through the configurational energy landscape towards the native structure. Although most proteins have evolved to fold efficiently into a unique native structure, misfolding (the formation of non-native structures) occurs frequently in vivo causing a...

Surface Interaction Mechanisms between Deformable Bubbles and Hydrophobic Surfaces in Aqueous Solutions
DownloadSpring 2018
Deformable bubbles in complex fluidic systems are crucial components in a variety of traditional and emerging industrial processes, where their surface interactions with hydrophobic surfaces play an important role in realizing the targeted functionalities. In this project, a bubble probe atomic...

The treatment of oil sands process-affected water by submerged ceramic membrane microfiltration system
DownloadFall 2014
With the rapid expansion of the oil sands exploitation in Northern Alberta over the past decade, oil sands process-affected water (OSPW) management has become a significant issue. In this study, the use of a submerged microfiltration was proposed as a potential process for pretreating OSPW....

Toxic effects induced in mammalian immune cells after in vitro exposure to oil sands process-affected water and its fractions
DownloadFall 2019
Oil sands process-affected water (OSPW) is produced by the surface mining industry in Alberta as a byproduct of the Clark hot water process, the currently used extraction method of crude oil from bitumen/tar sands. Under a provincial zero release policy all produced OSPW must be stored on site....
