Probing the Interaction Mechanisms among Asphaltenes, Fine Solids, Water-Oil Emulsions and Pipeline Surfaces in Oil Sands Production
DownloadSpring 2020
Fouling problem has been one of the most challenging problems in oil industries. Asphaltenes, fine solids, and water-oil emulsions have been regarded as the major components in the fouling phenomena during oil production. Investigating the interactions between foulants (e.g., asphaltenes, fine...

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...
