A phase change material (PCM) can store and release a large amount of heat through a solid/liquid transition when it is available for the later heating and cooling applications. However, PCMs have a very low thermal conductivity that leads to a higher charge and discharge time. To increase their thermal conductivity, I added nanoparticles to […]

Large quantities of data are constantly acquired during underwater acoustic surveys for environmental monitoring and resources management. The data, visualized as 2D images, are typically analyzed manually or semi-automatically by experts (marine biologists, acousticians, oceanographers), which is time-consuming and prone to errors and inter-expert disagreements. The goal of the proposed research project is to develop […]

This project will explore the interaction between sediment and oil that has been stranded on a shoreline as a result of an oil spill. More specifically, this project will investigate how stranded oil can entrain or adsorb oil and, as a result, sink and contaminate the marine environment. The two proposed oils to be tested […]

CHORE aims at the design of a biohybrid synapse between biological neuronal cells and organic neuromorphic devices made of CHORE aims at the design of a biohybrid synapse between biological neuronal cells and organic neuromorphic devices made of a conjugated polymer-based hydrogel which is sentitive to ions released by ther biologtical counterpart. The project icludes […]

Renewable hydrogen (H2) carriers such as methanol (MeOH) can be reformed back into H2 and is a fundamental chemical conversion for the long-term viability of the H2 economy due to its high density and ease of transportability compared to H2. MeOH is an especially important carrier as it is a simple C1 chemical that can […]

Mining-induced stress in the area around tunnel openings represents a major design consideration in potash mines. In the past, induced stress has been monitored using an array of techniques derived from the hard rock mining industry, one of the key assumptions being linear-elastic deformation behaviour of the rock. When using these methods in a soft […]

Clean electrochemical energy conversion is critically needed to build energy security that reduces Canada’s reliance on fossil fuels. The polymer electrolyte membrane (PEM) fuel cell is a particularly important part of a clean energy future as an attractive alternative to the internal combustion engine for transportation applications. PEM fuel cells offer zero local emissions, fast-start […]

Metal additive manufacturing (AM) technologies are now frequently used in the aerospace, automotive, medical, and energy sectors for fabricating end-use components. The digital nature of the supply chain involved for metal AM production becomes increasingly susceptible to numerous types of cyber- and cyber-physical threats. There is a need for developing security and traceability markers embedded […]

From an energy production perspective, the mobile component of the turbine, the runner, plays a key role in the operation of a water turbine. In the present competitive situation of deregulated energy markets, there is a great demand for more efficient runners which can withstand severe operating conditions. Traditional trial-and-error runner design methods largely depend […]

Naphthenic acids (NAs) represent the primary source of acute toxicity in oil sands process affected water. Due to the seepage potential of NAs from oil sands tailings ponds into the surrounding surface water and groundwater, environmental monitoring of NAs in water samples from tailing ponds, surrounding groundwater and surface water, and groundwater wells became a […]

With the rapid development of the economy, the demand for electrical energy storage is also increasing. However, the lack of high-efficiency, economical and reliable energy storage technologies makes it difficult for current electrochemical systems to utilize renewable energy and enable the circular economy fully. As an efficient and green energy storage device, the supercapacitor has […]

Avec la nouvelle ère numérique, quelques activités de gestion des actifs des infrastructures urbaines sont réorganisées au niveau des villes avec la mise en œuvre d’une panoplie de technologies. Ceci touche aléatoirement quelques activités, il manque une vision systémique et une compréhension holistique des besoins. Il existe un manque de bases théoriques soutenant le déploiement […]
