Transition metal dichalcogenides, such as molybdenum disulfide, can be thinned down from bulk crystals into few or single atomic layers that exhibit unique optoelectronic properties due to quantum confinement. The proposed work aims to exfoliate these materials into single to few layers using a new electrochemical exfoliation technique and to study their optoelectronic properties when […]

L’hydroxyurée est un médicament utilisé pour prévenir les complications de l’anémie falciforme ainsi qu’en chimiothérapie d’appoint pour certaines leucémies. En pédiatrie, l’hydroxyurée doit toutefois être ajustée selon le poids de l’enfant, ses prises de sang et la toxicité perçue. Or, au Canada, seule la formulation de 500 milligrammes est disponible. Ainsi, nos hôpitaux et nos […]

Le lithium et le tantale fait partie des minéraux critiques (MC) identifiés par le Canada. De nombreux gîtes à Li-Ta ont été répertoriés au Québec et afin de promouvoir l’exploitation responsable de ceux-ci, il est impératif de réaliser une caractérisation détaillée qui déterminera le modèle d’exploration, la ressource exploitable ainsi que les risques environnementaux. L’identification […]

Supercapacitors are energy storage devices that can be charged and discharged much faster than batteries while also being more reliable and exhibiting nearly indefinite cycle-life. Graphene-based materials which are a single layer of carbon atoms, exhibit the highest surface area of any material and have the potential to form the ideal supercapacitor electrodes, if we […]

Currently, the growing demand for electrical energy is driving the integration of renewable energy sources into modern power systems. However, integrating renewable systems has increased uncertainty in the operating conditions of the electric system. To address these challenges, the development of algorithms to optimize energy management in power systems, satisfying electricity demand while respecting physical […]

La bactérie Clostridioides difficile (Cd) est la cause principale de diarrhée infectieuse post-antibiotique dans les pays industrialisés (ICD). Bien que l’antibiothérapie soit le traitement standard contre les ICD, elle s’avère souvent inefficace pour empêcher la récurrence de l’infection. La phagothérapie est une alternative thérapeutique prometteuse, qui consiste à utiliser des bactériophages (phages), i.e. des virus […]

Ce stage s’inscrit dans un projet qui a pour objectif d’optimiser les contraintes mécaniques dans les lasers. Afin d’optimiser les résistances dans les lasers, l’optimisation des contacts ohmiques est primordiale. Ainsi, l’objectif de ce stage est d’optimiser les contacts ohmiques pour la fabrication de lasers, visant une faible résistivité. Différents empilements métalliques et d’autres moyens […]

The world’s rising environmental temperatures due to climate change have a severe impact on poultry, which is highly sensitive to heat due to lacking sweat glands and being covered with feathers. Researchers are focused on developing strategies to relieve heat stress in poultry, with dietary interventions being extensively studied. Heat stress affects appetite and animal […]

Big data analytics has emerged, in the past few years, as a subject of great fascination and intrigue. It has become a vital factor in the decision making process for leaders of various sectors, from government bodies to corporate executives to scientists and researchers. It has gained considerable attention recently due to the exponential growth […]

Metal additive manufacturing (AM), or metal 3D printing, enables “unique structures printed for unique functions” and “the right materials printed in the right place”. Therefore, it is the preferred fabrication method for creating functionally graded materials (FGMs), whose material properties varies over its volume to meet industrial needs. In this project, I leverage external magnetic […]

Graphene and related materials remain the most promising electrode materials and additives for use in energy storage devices such as batteries and supercapacitors due to the potentially high surface area, high aspect ratio and electrical conductivity. Unfortunately, it remains challenging to achieve single layers of graphene using scalable methods of production. The proposed work aims […]

Zircon, the oldest mineral found on Earth, provides a unique record of geological processes through time. Its extreme chemical and mechanical stability helps preserving these records upon the mineral transfer to the Earth’s surface and weathering. Zircon is a ubiquitous accessory mineral in silica-rich continental rocks, which has long been used as a tracer of […]
