Amélioration de capteurs à effet Hall pour la mesure précise du courant et du facteur de puissance

Les méthodes commerciales actuelles de supervision de l’énergie ne répondent pas aux besoins de l’industrie, car elles sont trop volumineuses, trop couteuses et elles demandent un temps d’installation important. Une approche prometteuse consiste à utiliser des capteurs à effet Hall afin de mesurer l'intensité du courant électrique d'un circuit à partir du champ magnétique produit par ce dernier. Bien qu'il permette la mesure du courant à faible coût, ce type de capteur présente une précision limitée en comparaison à d'autres technologies.

Étude sur l'efficacité énergétique et la stabilisation biologique et chimique de la technologie ATAD optimisée. Applications aux résidus domestiques et aux résidus verts

Devant l'augmentation des problèmes environnementaux dus aux changements climatiques causés par l'homme. Et face aux diverses solutions de protection de l’environnement, en terme de nouvelles technologies et/ou amélioration d'un procédé, les scientifiques cherchent constamment des solutions réalistes et raisonnables, voire de nouvelles technologies émergentes.

Swiss-Roll Mixed Reactant Fuel Cell Chemistries

The project proposes to explore a series of alkaline chemistries in a novel Swiss-roll mixed reactant fuel cell (MRFC).The Swiss-roll MRFC is a recently developed fuel cell architecture which promises to significantly reduce the complexity and cost of scaling up fuel cell systems to commercially viable power supplies. The Swiss-roll MRFC concept has been proved with borohydride fuel, but as the borohydride system is limited in terms of commercial application, it is necessary to explore other fuels.

Uncovering Sources of Plastics Waste in the Maritimes to Support Innovative Recycling Technologies

The project aims to collect and synthesize information pertaining to low-grade plastics waste streams in Atlantic Canada. The project will focus on type, quantity, quality, location, and current management practices of the plastics waste streams identified. Information will be gathered primarily from farmers, waste management groups, and key government informants in Nova Scotia. The intern will provide research support in all aspects of plastics waste streams as needed by Nova ReNew.

Abrasive Waterjet Polishing of Large Hydraulic Turbine Blades

The objective of this project is to improve the quality of the hard-to-reach areas of the hydraulic turbine blades using abrasive waterjet polishing method. By this way, the energy lost caused by parietal friction between the turbine blades and the flow will be decreased and consequently the efficiency of the turbine will be improved. Previously, the polishing process of some parts of the turbines was performed manually which caused uneven finished surface and poor quality in some areas. With this method, through a uniform polishing strategy, the desired surface quality can be achieved.

Modeling and simulation for predictive building control using high-resolution climateforecasting

The state-of-the-art of building energy management systems uses model predictive control to compare alternative control strategies prior to implementation. Climate conditions dramatically influence the control strategy selection. These rely on conventional climate forecasting that provides coarse resolution with respect to both time and space (e.g. 1 hour, 50 km). The industrial partner Green Power Labs Inc. (GPLI) and Dalhousie University propose to use high-resolution climate forecasting at the sub-hourly and building level resolution (e.g.

Development and characterization of catalyst electrodes for electrochemical reduction of CO2

Electrochemical reduction of carbon dioxide (ERC) is a process by which carbon dioxide (CO2) is converted into valuable chemical products via chemical reactions driven by electricity. The goal of this project is to fabricate and test catalytic metal electrodes to increase the efficiency of ERC reactors converting carbon dioxide from industrial exhaust gas streams into formic acid.

Low-Cost Ultra-Thin Flexible Silicon Photovoltaics

Performance optimization and prototype demonstration of the low-cost high-efficiency Localized Inherently Thin (LIT) solar cell technology platform will be carried out during the two year Mitacs Elevate Post Doctoral Fellowship program. The candidate will also design and optimize the fabrication process, working alongside industry staff, for technology transfer and commercialization. A business study will also be carried out as part of the program in order to establish the framework for large scale manufacturing.

Combined Harvesting and Storage of Solar Power

This project aims to develop a low cost, biologically inspired solar energy harvesting and storage device. This unique combination addresses the intermittent availability of sunlight during different times of the day by smoothing out variations in the output using stored energy. Solar energy will be captured by very efficient bacterial proteins that normally drive photosynthesis. The captured energy is harvested from the proteins and stored in a liquid salt solution that forms the bulk of the device.
