Fundamental Understanding of the Interactions between Elemental Selenium and Hydrophilic/Hydrophobic Particles in Wastewater
DownloadFall 2015
In this study, interactions between elemental selenium particles and different surfaces (i.e. Fe(OH)3, silica, octadecyltrichlorosilane (OTS) modified silica and selenium film coated gold) are investigated to understand the behavior of elemental selenium particles in wastewater treatment process....

Fall 2015
In this study, the flotation behaviors of chalcopyrite and pyrite single and mixed minerals in Milli-Q water, NaCl solution, and sea water were investigated. The performance of different collectors was evaluated. Collectorless flotation was also studied under potentiostatic control to explore the...

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...

Asphaltenes are the heaviest component in crude oil and bitumen. The molecular interactions and interfacial behaviours of asphaltenes are closely related to many challenging issues in oil production, which are believed to play an important role in stabilizing water-in-oil (W/O) and oil-in-water...

Molecular Dynamics Study of Clay-Polymer Interactions in the Treatment of Mature Fine Tailings
DownloadFall 2021
In this dissertation, all-atom molecular dynamics (MD) simulations were performed to study the mechanisms of clay-polymer interactions and the effects of solution chemistry in the treatment of mature fine tailings (MFT). The fine solids in MFT were mainly clay particles such as montmorillonite...

Mussels can obtain strong underwater attachment to virtually all kinds of surfaces including rocks, metals, wood structures, polymers and concretes by secreting mussel foot proteins to form byssus. Great efforts have been dedicated to understanding this behavior and it is found that an catecholic...

Prebiotic-Chemistry Inspired Polymeric Coatings for the Surface Modification of Hydrophobic Polyethersulfone membranes for the Enhancement of their Antifouling and Antibacterial Properties
DownloadFall 2020
Polyethersulfone (PES) membranes are very commonly used for wastewater treatment because of their excellent mechanical, chemical and thermal properties. However, the major concern associated with these membranes is their susceptibility to fouling due to their intrinsic hydrophobicity. Therefore,...
