Spring 2014
Introduction of a binding or reacting liquid into a gas-solid fluidized bed is common in industrial processes (e.g. fluid coking, catalytic cracking, granulation). Ability of the liquid to spread and the attractive effect on particles due to liquid bridge formation alter the fluidization behavior...

Spring 2021
At different stages during the extraction of bitumen from the Athabasca oil sands, the removal of unwanted fine solids whether suspended in aqueous or non-aqueous liquids continues to present serious challenges to the oil sands industry. These fine solids are unique in that their colloidal...

Tau seeding in a HEK cell model is influenced by aggregation inducers and cellular chaperones
DownloadFall 2022
The tau protein is a microtubule associated protein whose misfolding and subsequent aggregation have been associated with a group of neurodegenerative diseases known as tauopathies. Studying tau in a lab setting has been crucial for the advancement of knowledge and technology used to treat people...

Studying Structure-Nanoaggregation Relations of Polyaromatic Molecules in the Bulk Oil Phase and at the Oil-Water Interface Using Molecular Dynamics Simulation
DownloadSpring 2014
The detection, identification and characterization of early stage molecular association of polyaromatic molecules into nanoaggregates, where these nanoaggregates represent the first level of molecular clusters or building blocks are critical in areas such as design and fabrication of advanced 3-D...

Rheology of Bitumen at the Onset of Asphaltene Aggregation and its Effects on the Stability of Water-in-Oil Emulsion
DownloadFall 2015
Asphaltenes are the heaviest fraction of bitumen. Asphaltenes not only play an important role in the high viscosity of bitumen but also in the water-in-oil (W/O) emulsion stability. Nevertheless, their exact function in the stability mechanism of W/O emulsion still remains unresolved. It is...

Spring 2015
Colloidal-collector interactions are of fundamental importance in separation and filtration technologies. Here, the effect of collector grains on the behavior of colloidal particles was studied in two different experimental systems, i.e., column studies with stationary collectors and batch mixing...

Fall 2012
This thesis explored the properties of asphaltene nano-aggregates in crude oil and toluene based solutions and fouling at process furnace temperatures, and the links between these two phenomena. The link between stability of asphaltenes at ambient conditions and fouling at the conditions of a...

Spring 2010
Most crude oils contain traces of vanadyl porphyrins within their asphaltene fraction. Although these metals are only present in trace quantities, they have a significant detrimental impact on crude oil processing units; therefore, their selective removal is highly desirable. The current work...

Spring 2015
In many applications, it is desired to separate unwanted fine particulates from a liquid by gravity settling. An efficient separation, however, will be feasible only if a combination of aggregation and sedimentation occurs. To understand the kinetics of such a process, a mathematical model that...
