The development of CO2-switchable polymers as draw solutes for forward osmosis

Current methods for concentrating (removing water from) food and drinks for their transportation and/or storage rely on thermal or ultraviolet processing that is ultimately detrimental to the food product. This research proposes a novel method to remove the water that is based on forward osmosis, which solely depends on the ability of the draw solution to “draw” the water from the food across a membrane without the need to use pressure or heat.

Accelerate development of new technologies and applications for advanced water treatment - Year two

Global population growth, urbanization and changing climate patterns have increased the demand for potable water, wastewater reuse and value recovery from wastewater, and treatment 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.

Valorization of surface enhanced pulp fibers into value-added products

Domtar Inc. is investigating potential value-added applications for an advanced fiber they produce, which is referred to as SEPF (surface enhanced pulp fiber). SEPF is a key platform material for the development of new value-added, bio-based products from existing pulp and paper manufacturing sites and their forest based supply chains. The main objective of this work is to use SEPF for the preparation of said value-added products, such as, for example, paper, paperboard, or fiber-reinforced plastics, among others.

Advanced Data Science Research for Social Good II

Municipal governments and urban centres across Canada are being inundated with data—data that have potential to improve public service. Despite this, local governments do not have enough data expertise to extract insight from these overwhelming datasets. Simultaneously, high-quality personnel (HQP) in the domains of data science and urban analytics lack opportunities to work closely with local government to address this gap.

Vanadium oxide coated with conductive polymers for zinc-ion battery cathode

Rechargeable aqueous zinc ion batteries (RAZBs) have been used extensively because of their safety and low-cost. As an available cathode material for ZIBs, layered vanadium oxide (V2O5) has been considered due to its high specific discharge capacity. Because V2O5 is slightly soluble in water, it is suitable for modifying V2O5 with conductive polymers to stabilize its crystalline structure and decrease the solubility of V2O5 in aqueous electrolyte systems. In-situ polymerization will be used to coat polymers on the V2O5 surface.

Gelatin modified separator for dendrite free metal anode

In commercial batteries, metal anode-based batteries, mainly using zinc or lithium as the anode, provide higher battery capacity than traditional metal ion batteries. Lithium metal anodes have a theoretical specific capacity 10 times higher than commercial lithium ion batteries with graphite as the anode. Zinc anodes are excellent anodes for use in aqueous batteries, because they offer the highest energy density of all aqueous battery systems and low cost.

Peptide-Based Environment Sensitive siRNA Delivery System for Cancer Treatment

In this project, the main objective is developing a peptide-based environment sensitive siRNA delivery system for cancer treatment. If this deliver system can be proved efficient both in vitro and in vivo, it could have potential feasibility to be further characterized and become a pharmaceutical drug eventually.

Systematic Risk Mitigation Methodology Applied to the Bioénergie La Tuque (BELT) Biofuels Biorefinery - Year two

Bioénergie La Tuque (BELT) is promoting the development of a 200 million liter per year biofuels plant to be built by 2023 in La Tuque. The plant will use residues from forest harvesting as feedstock, which will be a first at that scale for a second-generation biomass biorefinery in Canada. It is critical for a project of that magnitude to achieve success, that risk associated with the biorefinery implementation are thoroughly identified and mitigated. In this project, technology and market risk factors are specifically targeted.

Investigation on processes for removal of chloramines from saturated sodium chloride brine solution

ERCO Worldwide, A division of Superior Plus LP, Saskatoon facility ("ERCO Worldwide-Saskatoon") is a manufacturer of caustic soda, chlorine, hydrochloric acid and sodium chlorate. This facility has four fully developed underground brine wells. The brine solution as produced from the brine wells contains 26% sodium chloride in it. This saturated brine is purified and supplied to the electrolyzer system to produce caustic soda, chlorine, hydrochloric acid, and sodium chlorate.

Evaluating the effectiveness of novel chemically modified chars, in conjunction with other organic and inorganic residuals from the forestry and pulp & paper industries, for enhanced passive treatment of mine-influenced water

This research will test the efficacy of sulphate and metals removal from mine-influenced water using passive or semi-passive technologies. Critical to successful application of these technologies is creating conditions that support microorganisms that mediate precipitation of metal sulphide minerals.
