Regenerable Composites for Removal of Organic Dye in Aqueous Media and Water in Heavy Oil and the Associated Interaction Mechanism
DownloadSpring 2018
Water plays an indispensable role in all aspects of life, including farming, domestic and industrial uses. In industries, water has been extensively applied in mining, production and surface treatment, producing a large quantity of contaminated water that threatens human health, endangers...

Spring 2016
In this study, a two-step flocculation method by combining anionic and cationic polymeric flocculants on the treatment of oil sands tailings was investigated. Compared to conventional flocculation by using a single anionic or cationic polymer, which has been a widely exploited procedure for...

Reclamation of Unconventional Oil Processed Water through the Adsorption of Naphthenic Acids by Carbon Xerogel
DownloadFall 2017
This study examines the use of carbon xerogel (CX) material for the adsorption of naphthenic acids (NAs). The adsorption of NAs is crucial for the reclamation of unconventional oil processed water, more specifically Alberta’s oil sands process-affected water (OSPW). CX material is synthesized at...

Localization Model description of interfacial dynamics of free-standing nanoparticles and thin films, and nanoparticle on supporting interacting substrate
DownloadFall 2022
Localization model (LM) relates, without any free parameter, slow dynamics of α-relaxation time (τα) to fast dynamics of Debye-Waller Factor (DWF) or ⟨u2⟩, which is the mean square displacement of particles at a caging time on the order of picoseconds. Moreover, localization model can also...

Stimuli-Responsive and Self-Healing Nanocomposite Hydrogels Based on Reversible and Dynamic Crosslinks
DownloadFall 2022
Hydrogels, due to their soft and water abundant natures, highly resemble human skins and tissues and thereby have attracted extensive attention in recent years. Functional hydrogels showing responsiveness to various stimuli such as pH, temperature, strain and pressure are promising for a wide...

Dynamic Interfacial Tensions and Dilatational Viscoelastic Properties of Asphaltenes at Oil/Water Interface at High Pressure and High Temperature Conditions
DownloadFall 2021
The dynamic interfacial tension and dilatational viscoelasticity behaviors of asphaltenes at oil/water interfaces were investigated by means of an oscillating droplet tensiometer. This oscillating droplet tensiometer was modified to handle temperature of 120 °C and pressure up to 700 kPa. For...

Functional materials for destabilizing and stabilizing emulsions and underlying interfacial interaction mechanisms
DownloadFall 2021
Oil related issues such as oil/water emulsions are critical challenging issues in a wide range of engineering processes and have caused negative effects to economy, environment, and ecology. Despite much effort devoted to this area, the developed materials remain many limitations. For example,...
