Enzymes are macromolecules that speed up the rate of chemical reactions by many orders of magnitude. Different classes of enzymes are present in a cell at different copy numbers to control and fine-tune its metabolism. The kinetics of enzymes differs depending on the physical properties of the local surroundings. Due to the high complexity of […]

With the increase of CO2 emissions, pollutants and waste production from developed/developing countries, there has been an urgent need for the scientific community to come up with effective and reliable solutions to these environmental concerns. The demand for renewable and clean energy alternatives has never been so urgent. While there have been developments in various […]

Due to increasing rates of childhood obesity, it is important to investigate the relationship between motor skill development, physical activity, body composition and sleep patterns. Previous research in this area has focused on school-aged children and adults, when daily habits have already formed and are difficult to modify. The purpose of this project is to […]

Dans ce projet, diverses approches de synthèse du LFP seront utilisées soit par plasma thermique à couplage inductif, par méthode sol-gel et par méthode co-précipitation. Ces matériaux seront caractérisés par spectroscopie d’impédance électrochimique pour déterminer les valeurs de coefficients de diffusion des ions lithium dans les particules. Afin de déterminer ceux-ci, nous proposons un modèle […]

Memristor, as the name suggests is a contraction of “memory resistor”, a novel device that was proposed almost fifty years but only realized recently for the first time. Memristor, the missing link in the manifold of circuit elements, is expected to usher a wave of innovative integrations in electronics and yield novel functionalities. Memristors would […]

Les huiles essentielles sont remplies de produits naturels qui peuvent avoir des utilités variées. Malgré tout, les recherches portant sur la composition moléculaire d’huiles essentielles demeure limitées. Les plantes du nord sont exposées à des stress environnementaux particuliers, qui enrichissent et rendent leur composition moléculaire intéressante. Elles peuvent renfermer des produits naturels inédits, retrouvés nulle […]

Inhalation exposure to mercury continues to be a concern in a number of workplaces. Examples are facilities handling mercury-containing electronic waste or so-called “gold-shops” processing the amalgams from artisanal and small-scale gold mining operations. We are exploring the feasibility of using a passive air sampler recently developed for recording long term average mercury concentrations in […]

When a light source is focused onto a metallic nanoparticle, a phenomenon called localized surface plasmon resonance occurs and can be utilized to guide light, perform highly sensitive spectroscopy measurements and induce efficient surface chemistry reactions. The “hot-electrons” generated by the light excitation are triggering the chemical reactions that could not be initiated otherwise. This […]

Au Québec, environ 360 000 travailleurs sont exposés quotidiennement à des niveaux de bruit susceptibles d’engendrer des problèmes d’audition. Les bouchons d’oreilles individuels sont souvent utilisés pour pallier ce problème. Cependant, l’inconfort lié à l’utilisation de ces protecteurs limite leur durée d’utilisation et donc leur efficacité. L’objectif de ce projet est de concevoir des outils […]

La tomographie d’émission par positrons (TEP) est une modalité d’imagerie médicale permettant le diagnostic et le suivi de cancers, maladies neurodégénératives et maladies cardiométaboliques. La prochaine percée majeure en imagerie TEP repose sur la mesure de temps-de-vol (TdV) ultra-rapide, nécessitant une excellente résolution temporelle des détecteurs du scanner. Les détecteurs conventionnels ne possèdent malheureusement pas […]

The Deer Cove gold mine is located approximately 4.2 km north of Ming’s Bight near Baie Verte, north-central Newfoundland. Free gold has also known to occur in the surrounding till. While preliminary studies have been done it is still unknown if the gold in the till can be economically and more importantly environmentally recovered using […]

Production of rutin, a high value of nutraceutical, from buckwheat hay in Manitoba has the potential to be much less labour-intensive and inexpensive compared to that produced offshore from other crops. However, the optimum drying condition of buckwheat hay and the relationship among drying conditions, harvest times and the amount of rutin in the dried […]
