Chemicals manufactured and used in society degrade through physical and biological processes (e.g., photolysis, biotransformation) into break-down products (e.g., metabolites). Most “parent” chemicals can breakdown relatively quickly so that they are not persistent or bioaccumulative; however, some metabolites formed during the degradation processes can persist in the environment thus requiring consideration for ecological and human […]

The study of high-intensity laser-matter interaction is very promising in terms of extracting rich fundamental physics involved behind various phenomenon happening at the atomic level. Such studies have been made possible only due to the development of very sophisticated laser systems capable of delivering optical powers comparable to the strong inter-nuclear attractions holding together the […]

Increased awareness of the issues associated with using opioids such as morphine that target the mu-opioid receptor – namely, that these drugs tend to lead to dependency and significant, often life-threatening, side effects – have led researchers to identify the delta opioid receptor as an alternative, and potentially safer, target for the management of chronic […]

Le stage propose dans Ie cadre dc cette demande s’inscrit dans un projet plus vaste mene par Dominique Gravel, Christian Messier, Yves Bergeron et moi:meme, subventionnc par Ie FQRNT pour la periode allant de Janvier 2011 a Janvier 2015. L’objectifprincipal de ce projet est d’avoir une meilleure comprehension des phenomenes sous-jacents is la migration des […]

Enzyme immobilisation is crucial for preserving the enzyme activity while enabling the enzymes to be recovered and reused for multiple applications in biocatalysis. However, immobilisation can change the structure and functionality of enzymes. Therefore, immobilisation of enzymes needs to be carefully investigated and controlled at fundamental levels. The emerging two-dimensional (2D) materials, such as graphene […]

nEXO is a planned rare nuclear decay search in xenon-136. The experiment will tell us whether the neutrino, somewhat like a charge-less and extremely light electron, and its antiparticle are identical. However, nEXO has extremely low backgrounds and thus is sensitive to a lot more than just decays in xenon-136. Core-collapse supernovae are stellar explosions […]

Ce projet vise à développer des applications pour les filaments de celluloses (FC) de Kruger Biomatériaux (KBI) comme fibres de renforcement au sein de polymères thermoplastiques (PTP), thermodurcissables (PTD) et polyuréthane (PU. Leurs bonnes propriétés mécaniques, faible densité, faible abrasivité et biodégradabilité en font une alternative verte de choix pour remplacer les fibres synthétiques comme, […]

Les objectifs et finalités du stage : On propose ici à l’étudiant l’analyse d’un système modèle de l’effet Casimir se manifestant par l’attraction de deux miroirs se faisant face dans le vide. Ici, les fluctuations de point zéro seront apportées par l’intermédiaire d’un champ acoustique ad-hoc qui excitera le système des deux miroirs acoustiques. L’étudiant […]

The aim of this is to produce a comprehensive database of Cherenkov emission/absorption spectra in ordered liquids (ionic liquids and solutions of nanomaterials) under differing thermodynamic conditions. This database will be valuable in creating a quantitative model and theoretical models able to predict the spectra of a given material under given conditions with an ultimate […]

Le sujet proposé porte sur la dualité onde-particule. On propose ici à l’étudiant l’étude expérimentale d’un système modèle qui vise à tenter une représentation mécanique du système quantique onde-particule. L’étudiant aura en charge un banc expérimental composé d’une masselotte pouvant coulisser sur une corde vibrante, le tout étant instrumenté notamment par un système d’imagerie rapide. […]
