A fundamental study of bubble-particle interactions through zeta-potential distribution analysis
DownloadSpring 2011
Understanding the mechanism of bubble-particle interactions plays a critical role in advancing flotation technology. In this study, submicron size bubbles with an average diameter less than 1 μm and a life time of at least several hours were generated using a novel hydrodynamic cavitation method....

A Molecular Dynamics Study of the Dissolution of Asphaltene Model Compounds in Supercritical Fluids
DownloadSpring 2011
The demand for a new solvent to treat oilsands was behind the purpose of this project; molecular dynamics simulation was used in this study. Supercritical water, supercritical carbon dioxide and other selected organic solvents in their supercritical state were studied. Meso-tetraphenyl porphyrin...

Fall 2011
A cationic thermal sensitive polymer, polyN-isopropylacrylamide-co-N-[3-(Dimethylamino)propyl]methacrylamide (CP) of different molar ratios, known as CP05 and CP10 was synthesized in-house. By doping aluminum hydroxide (Al(OH)3) colloids into CP during the polymerization process, a novel hybrid...

Spring 2011
A Surface Forces Apparatus (SFA) was used in this study to investigate the fundamental surface forces in oil sand processing research. Asphaltene coated surfaces were chosen as the research topic due to the critical role of asphaltenes in oil sands processing, from bitumen extraction, froth...

A study of passivity and stress corrosion cracking (SCC) of alloy 800 in simulated steam generator crevice solution containing thiosulfate and sulphide species
DownloadFall 2011
The passivity and stress corrosion cracking (SCC) behavior of Alloy 800 was studied in test solution containing thiosulfate and sulphide species. Cyclic polarization experiments in thiosulfate containing solutions indicated that with an increase in the concentration of thiosulfate, both the...

A study of the colloidal stability of mixed abrasive slurries of silica and ceria nanoparticles for chemical mechanical polishing
DownloadFall 2011
Slurry stability is an important factor in Chemical Mechanical Polishing (CMP) efficiency. However, few studies have been done in this respect. In settling tests at pH 4, adding various amounts of ceria to colloidal silica slurries was shown to change the stability of the resulted mixed abrasive...

Fall 2011
Air Separation is the largest industrial separation process in the world in which air is separated to its primary constituents including, nitrogen, oxygen, and argon. Technical gases are applied in many important industries such as steel industry, chemical processes, oil and gas production,...

Spring 2011
A major challenge to any “solvent-based” bitumen extraction technology is the removal of suspended fine solids from the hydrocarbon medium (i.e. diluted bitumen). To address this problem, we examined how colloidal solids could be made to aggregate in a hydrocarbon medium and thus be separated by...

Fall 2011
Oil sands industry, with the collaboration of its research partners, has been striving to come up with cost effective and environmentally friendly technology for de-watering of mature fine tailings (MFT). Overall objective of present study was to determine the optimum dosage of suitable polymer...

Annihilation of cardiac alternans by electric and mechano-electric feedback (MEF) in a cardiac tissue
DownloadFall 2011
Alternans occur prior to ventricular fibrillation and is a medical condition of heart that leads to sudden cardiac death (SCD). The presence of the electrical alternans induces, through the mechanism of the excitation-contraction coupling, an alternation in the heart muscle contractile activity....
