Biodegradable Protein Based Tailings Flocculant

Description
A by-product of bitumen extraction, mature fine tailings (MFT) are a mixture of fine solid clay, mineral particles and suspended hydrocarbons. MFT stable dispersion can last for decades and it is estimated that 800 million m3 are formed per year in Alberta. As of July 2012, the Energy Resource Conservation Board Directive 74 mandates that […]

Method to Create High-Quality Bio-Based Resins and Composites Using Renewable Oils

Description
Resins and composites are used in various industries including plastics, paints and varnishes, rust and wood protection, and floor tiling. Toxic, petroleum-based resins and composites have been used in the manufacturing industry for years. The use of petroleum-derived materials are becoming less and less attractive due to the uncertainty of future supplies, environmental concerns, and […]

Method to Improve Abrasion and Scratch Resistance in Polyurethane or Other Polymer Nanocomposites

Description
Polyurethane coatings are protecting many different structures today, such as storage tanks, oil and gas pipeline, water and wastewater, bridges, ships, and other facilities. The products have been effective because of their outstanding life expectancy and performance such as resistance to aggressively corrosive environments, high abrasion resistance, fast application, low and cold temperature curing capability […]

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┬ábe 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, […]

Silicon Nanocrystal Optical Resonator

Description
Silicon is the principal material used in microelectronics, due in part to its low cost and high abundance. However, there are problems inherent in the miniaturization of conventional microelectronics, such as cross-talk (interference) and increased heat dissipation. To overcome these challenges and to increase the speed of computing, there is a push towards photonics, particularly […]

Polymer-Based Muscles and Actuators

Description
Materials that spontaneously undergo a change in structure, for example, from a two dimensional (2D) to three dimensional (3D) structure in response to external stimuli have been of great interest as artificial muscles, and for fabricating novel actuators, switches, valves and in robotics. Hydrogels are of particular interest owing to their mechanical properties, chemical diversity, […]

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 […]

New Methods of Phosvitin Extraction from Egg Yolk

Description
Phosivitin is a principal phosphoprotein in egg yolk, representing about 11% of egg yolk proteins and about 4% of yolk dry matter. It exhibits many advantageous properties that would be useful to various industries, including, notably, a greater metal chelating ability than casein phosphopeptides, which are currently used in calcium supplementing agents. Phosvitin also exhibits […]

Optical Measurement System for Measuring Liquid Properties

Description
The researchers at the University of Alberta have developed a new apparatus and method for measuring the quality and optical properties of liquid in a commercial test cell using the principle of low coherence interferometry. This technique is highly suited for testing and observing phase transitions and condensation of hydrocarbon samples at high pressure and […]
