Charaterizing Effects of Dye on Microbubble Shells

In photoacoustic (PA) imaging, pulsed light irradiates a sample. Light-absorbing molecules experience a pressure rise and generate an ultrasound wave, from which, an image of the sample is obtained. If the image contrast is insufficient, contrast enhancement is applied by locally introducing stronger light absorbers. In ultrasound imaging (US), shelled gas bubbles are used to […]

Développement d’un système de dosimétrie à scintillation multipoints

En 2019, environ 200 000 Canadiens seront diagnostiqués d’un cancer. La moitié de ces patients seront traités par radiothérapie. Si l’objectif est de maximiser l’irradiation de la tumeur et minimiser l’impact sur les organes sains environnants, des erreurs pouvant avoir des conséquences désastreuses se produisent. Actuellement, aucune vérification en temps réel de la dose radioactive […]

Contrôle des interactions non linéaires dans les fibres optiques

Lorsqu’une impulsion lumineuse intense se propage dans une fibre optique, des interaction non linéaires surviennent et modifient le contenu spectral de l’impulsion. De façon imagée, l’impulsion lumineuse change de “couleur” à mesure qu’elle se propage dans la fibre. Ces interactions non linéaires sont étudiées exhaustivement depuis l’avènement du laser en 1960. Cependant, l’étude de la […]

Stereoretentive-Enantioconvergent Catalysis: A New Concept in Asymmetric Synthesis

This project will experimentally establish a completely new method for accessing enantiopure materials starting from racemic substrates: stereoretentive-enantioconvergent catalysis. The ability to synthesize chiral molecules in enantiopure form is vitally important, most recognizably for the pharmaceutical industry. This is because the molecules of life are chiral (e.g., D-sugars and L-amino acids) and enantiomers often interact […]

Preparation of Mesoporous Oxides for Electrochemical Applications

Electrochemical technologies, such as fuel cells and electrolysers, could play an important role in the attempt to diversify the energy market. These devices can be used to produce clean, renewable energy and fuels. However, the technology cost is still far too high, preventing their large-scale implementation. A significant portion of the production cost comes from […]

The physics of Boltzmann machines

Artificial Neural Networks are powerful tools used in the field of artificial intelligence. Inspired by the human brain, they have shown very good results in certain tasks, such as image classification and even in the generation of new images. The problem with neural networks is that we do not understand why they are working so […]

Protoporphyrin IX a novel crosslinker for dielectric elastomers

Dielectric elastomers or “artificial muscles” are a class of electroactive polymers that undergo expansion when subjected to an applied electric field. Polysiloxanes commonly referred to as silicones are often the material of choice for dielectric elastomers due to their excellent mechanical properties. However, they suffer from minimal expansion when subjected to an electrical field. This […]

Interactive Molecular Modelling in Virtual Reality

The work that the Glowacki lab has addressed concerns two main issues of VR: a lack of multi-user interaction and heavy processing requirements. Using remote cloud supercomputing facilities, his lab can access the processing power to model in real time incredibly complex mathematically systems, with the computational physics simulations performed off-site, thereby enabling multi-user interactions. […]

Contribution à l’optimisation géotechnique et économique des fosses minières

L’objectif principal du présent projet est d’améliorer et de valider une approche globale et intégrée de l’analyse de la stabilité des pentes minières. Il permettra également d’améliorer la flexibilité et l’adaptabilité de l’approche permettant de considérer rapidement un nouveau design de fosse et/ou de nouvelles données géomécaniques. Ceci est un atout majeur étant donné la […]

Modeling the viscosity of binary and ternary mixtures of ionic liquids

Ionic liquids are organic-cation salts that feature the property of being liquid at lower temperatures than their inorganic counterparts. This peculiar characteristic added to their versatility and recoverability make those compounds excellent candidates for many applications such as a replacement for conventional toxic and hardly recyclable organic solvents, among others. However, their high viscosity is […]

Green Chemistry for Green Solvents

This project focuses on the development of new solvents, to replace those that are currently used in industrial processes. Currently, the majority of solvents used in industry are harmful to both people and the environment. These solvents are full of volatile organic compounds, which are released to the atmosphere and contribute to smog formation. Globally, […]
