This proposal aims to investigate vocal production by users of Med-El cochlear implants (CI), in response to feedback alteration of their voice pitch. The originality of this proposal is to shift the usual focus of CI research from perception to production. We feel that the history of Med-El research on pitch coding would strongly benefit […]

Due to the limited sources of fossil fuel and growing demand of world-wide energy, research on inexpensive alternative energy sources has significantly increased past few years. While the conventional silicon solar cells are expensive, they are also unable to provide enough energy density for current and future societal needs. Semiconductor polymers are excellent candidates as […]

The main intended research activity of this international collaboration is to fabricate protective composite layered coatings for hydraulic turbine systems. The use of self-lubricating polymer bearings has become popular in order to reduce maintenance costs caused by the manual application of oil or grease lubrication. However, such materials are not suitable for larger loads, and […]

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 […]
