Fall 2011
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...

Fall 2011
This research was undertaken to study the performance of paraffinic solvents at higher temperatures for heavy oil/bitumen recovery. Heavy oil or bitumen saturated glass bead packs, Berea sandstone and carbonate cores were used in the experiments to represent different types of pore structures,...

Fall 2011
Molecular dynamics simulations were performed to investigate hydrogen interaction with edge dislocations during deformation in α-Fe. In particular, uniaxial tensile tests at different hydrogen concentration were conducted in a single crystal iron with high density of edge dislocations introduced...

Asphaltenes are the heaviest components in crude oil. It is generally believed that asphaltenes adsorbed at oil/water interface can form a protective layer to stabilize the water-in-oil emulsions. Therefore, it is of both fundamental and practical importance to understand the adsorption kinetics...

Crude oils contain a distribution of molecules with diverse chemical structures and molecular weights. Asphaltenes are considered the most problematic of these structures. We have investigated the adsorption and aggregation of asphaltenes on surfaces using scanning probe microscopy. Modifying the...

Fall 2016
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 Investigation on the Aggregation of Polyaromatic Compounds in Water and Organic Solvents
DownloadFall 2015
Aggregation of polyaromatic (PA) compounds has drawn great interest due to their wide impacts in areas such as petroleum processing. Despite the extensive studies on PA compounds, fundamental knowledge of their aggregation behaviors is still missing at atomistic level. For instance, it’s still...

Molecular Dynamics Simulations of Polyethylenimine Mediated Nucleic Acid Complexation with Implications for Non-viral Gene Delivery
DownloadSpring 2013
Gene therapy is a promising therapeutic technique that involves delivering nucleic acids into cells. Polycations have evolved into a major category of gene carriers. Polyethylenimine (PEI) is one of the most effective polycationic carriers. Furthermore, modifying PEI with certain lipophilic...

Spring 2016
Hybrids formed by biological entities and human-made nano-structures have been intensively studied in recent years due to their very interesting properties and applications. DNA-carbon nanotube (CNT) hybrid is one such material and the motivation of this PhD study. The interaction of DNA building...
