Two-Stage Hydrophobic and Hydrophilic Aggregation for the Flotation Separation of Fine and Ultrafine Minerals
DownloadSpring 2023
In mineral processing froth flotation is the most important technique to recover and separate different minerals. However, the flotation process deteriorates significantly with low efficiency and selectivity when mineral particles are smaller than 20 µm. Low flotation kinetics of fine hydrophobic...

Transition Metal Oxides Anchored onto Heteroatom Doped Carbon Nanotubes as Efficient Bifunctional Catalysts for Rechargeable Zinc-Air Batteries
DownloadFall 2021
It is well known that renewable energy, e.g., wind and solar power, are intermittent energy sources. This means that energy storage devices are needed to store the energy for when it is needed. Currently Li-ion batteries are used as these energy storage devices, not only for alternative energy...

Toward Direct Thermal-to-Electric Conversion: On-chip Microreactors for Catalytic Combustion of Methanol-Air Mixture
DownloadFall 2014
In this thesis, on-chip microreactors for catalytic combustion of methanol-air mixture were designed, fabricated and characterized. Using standard optical lithography, deep reactive-ion etching (DRIE) and other fabrication techniques, microreactors with integrated micropillars having four...

Total Internal Reflection Fluorescence Microscopy to Study Bitumen and Clay Interaction in Oil Sands Tailings
DownloadFall 2016
Oil sands tailings management remains to be a major challenge for oil industry in Canada. Promoting quick settling of fines in tailings ponds is the key to its treatment. Bitumen lost to tailings during oil sands extraction is also believed to hinder settling and consolidation of clays in...
