A Facile Synthesis and Application of Protein-Shelled Microbubbles as Temperature-Responsive Drug Carriers with the Aid of a Poly(N-isopropylacrylamide)-block-(acrylic acid) Shell
DownloadSpring 2017
In this study, a novel synthesis of proteinaceous microbubbles (MBs) was introduced in an effort to substantially lengthen the short lifetime of the sonochemically-synthesized microbubbles using surface-treated proteins. Bovine serum albumin (BSA) as a representative protein, was treated with...

Depression of Lead-activated Sphalerite by Sodium Hydrogen Phosphate for Red Dog Mine Operation
DownloadSpring 2019
The inadvertent activation of sphalerite by lead ions have been noticed and studied for decades. In this study, flotation behavior of sphalerite upon lead activation was studied. Sodium hydrogen phosphate was applied as a main depressant to test its effect on improving Pb-Zn selectivity. Surface...

Electrocoalescence of Water Droplets in Oil Emulsions: Effect of Electric Fields, Surfactants, and Chemical Demulsifiers
DownloadSpring 2019
Stabilization of water-in-oil droplets during bitumen extraction and refining process poses a major challenge in the oil sands industry. These crude oil emulsions are stabilized by rigid films at water droplet-oil interfaces. The salty water remaining in oil causes equipment corrosion, catalyst...

Abundance of low rank coal and increasing demand for energy provide an incentive for upgrading the low rank coal due to their high moisture and oxygen content. Various analyses were done to study the effect of the hydrothermal treatment on the physical and chemical structure of coal. Treatment of...

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...

The Mechanism of Floc Formation by Hydrodynamic Cavitation and Its Application on Fine Particle Flotation
DownloadFall 2018
In recent decades, hydrodynamic cavitation has been used to enhance fine particle flotation recovery in mineral engineering. Such an increase was mainly attributed to the generation of flocs/aggregates of fine particles during the hydrodynamic cavitation process. However, the mechanism of floc...
