Mines wastes include tailings and waste rock. Tailings are crushed rock produced by mineral extraction and waste rock is coarse material excavated to create mine openings. These wastes are commonly disposed on the surface in tailings or waste rock piles, which could pose serious environmental and geotechnical issues. Backfilling the openings of underground mines with […]

Today, the development of complex products such as aircraft systems is still mainly based on a paper-based requirements and development process which leads to delays, cost overrun and sometimes failure to respond to customer needs. A structured, model-based design approach is considered promising to bring innovation and optimization in systems architectures. The project aims to […]

Le contrôle de qualité de produits pharmaceutiques s’effectue par différentes méthodes de laboratoire telles que les tests de dissolution et les analyses de chromatographie en phase liquide à haute performance (HPLC). Ces méthodes sont souvent lentes et dispendieuses. L’industrie se tourne présentement vers l’utilisation de sondes spectrales (e.g. infrarouge, Raman) pour le contrôle qualité. Ces […]

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. However, this initiative will […]

Solar energy is one of the best sources of environmentally friendly reliable energy. Metamaterials is one of the subjects of nanotechnology, which applies scientific and engineering principles to make and utilize very small things— things at the nanometer scale, where unique phenomena enable novel applications. How to improve the efficiency and reduce the cost of […]

Dans les résidences, le bruit de ventilation est considéré comme une source majeure d’inconfort. La connaissance et l’identification des sources de bruit de ventilateurs sont primordiales pour la conception d’un ventilateur silencieux et énergétiquement plus efficace. Dans le cas des ventilateurs fabriqués par la compagnie Venmar Ventilation ULC. le bruit large bande domine d’une manière […]

Cu and Ni minerals that have great economic value mostly exist in the form of sulfides, making them difficult to extract using hydrometallurgical processes. Currently, heap leaching is the most economical way to extract these metals from low grade ores. Copper recoveries of many chalcocite heap leaches report around 70% copper recovery. However, the chalcocite […]

Enhancing the current and power density in polymer electrolyte membrane fuel cells (PEMFCs) is one of the main challenges to their large-scale commercialization and hence in tune with the pending needs of the PEMFC industry. The volumetric power density in PEMFC stacks is strongly affected by the flow field plates due to their critical impact […]
