Allyl Monomers And Polymers From Glycerol

Description

In recent years, with the rapid expansion in biodiesel production, the biodiesel industry is facing the dilemma, on the one hand, of how to meet an ever-growing biofuel demand, and on the other, manage excessive crude glycerol so that it does not pose a threat to the environment. About 10-11% (w/w) glycerol is generated as […]

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 […]

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 […]

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, […]

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 […]

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 […]

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 […]
