The objective of this project is to design and fabricate electrically rechargeable zinc-air batteries. These batteries are highly promising due to their ability to store up to double the amount of energy as current commercialized lithium-ion batteries, based on both energy-per-mass and energy-per-volume measurements.
Gold is the most economically important mined mineral in Canada, with a production value of $8.7 billion in 2017. Quebec and Ontario together accounted for more than 75% of the mined gold production in Canada in 2017. Economic, efficient, yet safe and environmentally responsible gold extraction is vital to Canada's dynamic economy and environment, as well as the global competitiveness of Canada's gold mining industries.
Copper-based antimicrobial coatings could play a significant role in reducing infections in hospitals and care facilities, reducing spoilage in consumer appliances, and reducing fouling on the hulls of ships. In this project, the development of copper-based coatings will be pursued for a wide variety of surfaces using paints and other advanced coating technologies. The chemical and physical properties of the coatings will be characterized and improved to minimize costs while maintaining effective killing of bacteria and fungi.
Carbon nanofiber is a material with extraordinary mechanical, thermal, electrical, and chemical properties. It has applications in a wide variety of industries including transportation vehicles, concrete, electronic devices, textiles, ink, coatings, lubricants, tires, and agriculture. Yet, the production of carbon nanofibers is an expensive and energy-intensive process. This project targets to develop Carbonova cycle, a catalytic chemical process that enables producing premium quality carbon nanofibers from utilizing greenhouse gases and waste heat.
Global population growth, urbanization and changing climate patterns have increased the demand for potable water, wastewater reuse and value recovery from wastewater, and for remediation of industrial process water. Population growth also results in increased demand for the shipping of goods by ocean freight, with the associated risk of the transport of unwanted marine life from one location to another by the discharge of ballast water.
The proposed project would seek to develop a technology and identify adsorbents that are better able to remove impurities such as carbon dioxide (CO2), nitrogen (N2), and oxygen (O2) from biogas (mostly CH4, also referred to as natural gas) produced from landfills, using adsorption technology. Interns will be carrying out adsorbent screening, by determining kinetics and binary and multi-component adsorption behaviour. Promising adsorbents will then be selected and tested under cyclic conditions to determine their life cycle.
Currently, around the world municipal solid wastes creating a serious risk to human health and the environment; the cheapest and commonly used management technologies for these wastes are landfilling or combustion. However, landfill releases methane and other greenhouse gases, also it has potential to pollute surrounding soil and groundwater. On the other hand, municipal solid wastes can be processed via hydrothermal liquefaction technology to convert agricultural, kitchen and other organic waste streams into bio-crude oil that is environmentally green and carbon neutral.
Biomass is a key feedstock for the production of renewable fuels and chemicals with potential zero carbon emissions and at low cost. State of the art conversion of biomass to bio-fuels focuses on the pyrolysis of the feedstock at high temperature in conventional reactors. However, current technologies face many challenges to achieve lower costs than fossil fuels, higher yields, improved energy efficiency and product quality. This project aims to evaluate the production of renewable fuels from biomass using a dual spinning-disc reactor.
Most of the heavy oil and bitumen produced in Western Canada is transported through pipelines to refineries in North America. Prior to transportation, the high viscosity of those fluids must be reduced by either dilution with a light solvent or upgrading. The high costs associated with handling diluents has increased the interest in upgrading; that is, the thermal conversion of high viscosity heavy oil or bitumen into a less viscous product.
This project will be with Vena Medical that focused on creating a forward viewing imaging microcatheter to provide a real-time navigational perspective for interventional physicians. The Vena Microcatheter will make interventional procedures faster, easier, and safer for both patients and physicians. This project will investigate the novel polymer optical fiber with high flexibility and high-quality image transmittance for medical microcatheter.
