Polymer Nanofibers for Rapid Dewatering of Fine Tailings

Description
The main objective of tailings ponds remediation is to remove water so that a trafficable load-bearing surface can be produced within a reasonable time frame to allow subsequent reclamation. A tailings pond includes water, sand, clay and residual oil that remain after oil sands processing. Once in the pond, the sand quickly sinks to the bottom […]

Meta-material Thermal Emitter for Thermo-Photovoltaics

Description
Heat is considered as a byproduct of industrial processes. For example, average oil and coal based energy conversion processes account for thermal losses roughly within 50% to 60% of the total produced power. For small internal combustion engines, this number may climb as high as 75%. Thermal losses are also significant for renewable energy systems, […]

Non-Radiating In-Situ Heating for Oil Sands

Description
Viscosity is a major obstacle in the recovery of low gravity oil resources from heavy oil and bitumen reservoirs. Traditional oil recovery and well stimulation techniques using hot steam or fluid are not efficient due to prohibitive heat losses from injection wells and reservoirs. More importantly, commonly used thermal recovery methods cause greenhouse effects, adversely […]

Hyperspectral Imaging for Ore Froth Processing

Description
Closed loop assessment of mineral froth is typically not possible using conventional ore processing technology, because the assessment of product quality and prediction of product recovery require laboratory analysis. However, researchers at the University of Alberta have developed a novel technique for assessing ore froth quality in closed-loop mineral flotation systems using features of the […]

Electrical Energization and Wireless Power Transmission

 
Description
The proliferation of electronic devices in our digital age has necessitated more convenient methods of power transmission. With varieties of devices such as cell phones, tablets, laptops and digital media players, each requiring a different power plug, users have to cope with an annoying tangle of cables. The most prevalent wireless power transfer technology currently […]

Adhesives from Agricultural By-Products and Waste

Description
As a result of increased concerns over safety, environment and sustainability, protein-based adhesives have re-gained industry interest as an alternative to petroleum-based adhesives. A greater need now exists for modified protein adhesives that offer results comparable to their petroleum-based counterparts, and that can be produced at a reduced cost. It is currently estimated that up […]

Method to Enhance Oil Recovery from Fractured Carbonate Reservoirs

Description
As conventional sources of crude oil diminish, there is a need to exploit other fuel sources in a cost-effective, environmentally-friendly way. One relatively-untapped source is heavy oil/bitumen from fractured carbonates, which contain more than 60% of the world’s oil reserves. The estimated recovery of carbonate reservoirs to date is only ~10% due to the challenges […]

A New Experimental Technique in Measuring Contributions of Individual Components to Wear-Corrosion Synergism

Description
The damage to materials caused by corrosive wear is a complicated surface failure process that involves both the wear-accelerated corrosion and corrosion-accelerated mechanical failure. This synergistic attack that plagues many industrial facilities can cause severe material loss (e.g. erosion-corrosion of tailing pipes for slurry transfer). Although efforts have been made to resist corrosive wear, the […]
