Polymers are widely used as coatings, adhesives, biomaterials and many other applications. These successful applications rely on the physical and chemical properties of the polymer molecules and surfaces. One type of important molecular and surface interaction is hydrophobic interaction which is...

The fluid coking process is an example of upgrading processes that use hot solids to heat and crack bitumen into more valuable products. When liquid is sprayed into a fluid bed of hot solids, the solids tend to agglomerate. The reactions in these agglomerates are subject to complex heating,...

Biodegradation of poorly water soluble hydrocarbons, such as n-alkanes and polycyclic aromatic hydrocarbons (PAHs) is often limited by the low availability of the pollutant to microbes. Adhesion of microorganisms to the oil-water interface can influence this availability. Our approach was to...

Non-aqueous extraction technologies are currently being investigated as an alternative to the conventional water based process for extracting bitumen from oil sands. The reduced dependence on fresh water and land for creation of tailing ponds makes non-aqueous technologies a greener alternative....
