L’acide citrique est un acide produit par les microorganismes, plantes et animaux. Il joue un rôle central dans le métabolisme de pratiquement tous les organismes vivants mais il est aussi utilisé comme additif alimentaire pour la diversité de ses propriétés fonctionnelles (régulateur d’acidité, chélatant, acidulant, et antioxydant). Yarrowia lipolytica est une levure oléagineuse GRAS (Generally […]

Les milieux riverains naturels sont reconnus pour leur grande biodiversité qui s’avère disproportionnellement élevée par rapport à leur étendue. Paradoxalement, l’expertise actuelle en stabilisation de berges s’est développée sans grand égard à leur importante biodiversité. Pour comprendre et expliquer la biodiversité des communautés végétales riveraines, il est indispensable de prendre en compte les régimes de […]

Creping is a part of tissue paper production process in which a very thin layer of paper is adhered on a hot, big(6-8 m dia) rotating(~2000 m/min surface speed) metal cylinder and scraped off later using a sharp blade. This process permanently changes the mechanical properties of the paper layer making it very soft, stretchy, […]

La recherche de procédés chimiques permettant de dégrader la lignine, visant à faciliter la production de biofuel à partir de la biomasse, est devenu un sujet scientifique important ces dernières années. Dans cette optique, ce projet s’intéresse à la synthèse et la caractérisation de complexes métalliques à ligands radicalaires, basés sur le modèle de la […]

This project concerns a technological solution for the home support of elderly people. The objectives of this device are the detection and prediction of falls of the elderly. For this, a solution based on thermal cameras is envisaged. This technological choice is motivated by the fact that it is a totally passive solution, that thermal […]

My doctoral research focuses on developing scientific literacy in young children. Currently, in the field of science education, there are different interpretations of a scientific literate person and this includes being knowledgeable about scientific content and developing an ability to apply this knowledge in meaningful way. Despite the importance of teaching science to young children, […]

The project aims to validate the effectiveness of “phase contrast” synchrotron (x-ray) imaging techniques in detecting very small-scale features (particularly amyloid plaques) commonly associated with the onset of Alzheimer’s disease. This will be done though comparison of synchrotron-generated images of Alzheimer-afflicted brain tissue, against their optical microscopy image counterparts. The experimental process will involve five […]

The great interest of shifting towards biodiesel from vegetable oils or was fats is leading to a tremendous increase of glycerol production as an inevitable by-product. This waste sparked the need for glycerol valorization to justify biodiesel as alternative for diesel from petroleum. Our research efforts are to partially electro-oxidize glycerol into value-added chemicals in […]

The current picture of structure formation in cosmology suggests that initially over-dense regions of dark matter collapse to form halos. These halos also host most of the luminous matter like galaxies. However, we cannot trace the dark matter directly since it does not interact with light. Therefore, the relationship between the underlying cosmic density and […]

Lignin, a carbon neutral and an underutilized feedstock, can be used to produce a variety of products, such as oils, syngas, benzene, toluene, xylene as well as high molecular weight products such as wood adhesives (binders), carbon fibers and polyurethane foams using thermal, chemical, biological and electro-biochemical processes. Globally, approximately 64 million tonnes of lignin […]

Oligonucleotides will be structurally integrated within complementary architectures in order to synthesize hybrid nanomaterials featuring biomolecular-driven behavior. We plan to synthesize nanoparticles featuring nucleic acid conjugates embedded in the structural network, so that their dynamics could be programmed for cancer therapy. We intend to make use of the biodegradable organosilica technology developed in De Cola’s […]

Septic shock is an acute pathology that is the leading cause of admission to ICUs across Canada, and the developed world. Unfortunately, no treatment to date has yet to be proven beneficial. Cardiac failure is a major factor in the mortality induced by septic shock. A major player to be targeted in treating this dysfunction […]
