Over 90% new drugs cannot be used in market or perform inefficiently because of their poor water-solubility. Delivery of non-water soluble medicine by using biodegradable carriers can solve the problem. This research work aims to develop N-trimethyl chitosan chloride (TMC)-based nanoparticles used as a drug carrier for delivering non-water soluble medicine to enhance the therapeutic […]

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 […]

The ultimate goal of this project is to develop a fundamental understanding of inclusion evolution during a particular refining process in secondary steelmaking unit. The particular focus is firstly on developing a detailed characterization of the inclusions formed during refining in the Stelco Ladle Metallurgy Facility, and secondly on adapting the existing McMaster ladle metallurgy/inclusion […]

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 […]

Fibre reinforced polymers (FRP) have become an attractive solution to make infrastructure corrosion- and disaster-resistant. Cities like Toronto have numerous structures and bridges already retrofitted with FRP and many more underway. However, FRPs effectiveness and and durability is sensitive to extreme thermal conditions, which can cause significant mechanical and durability issues. Climate change, one of […]

We aim to develop human bone extracts mixed with commercially available bone putty and prepare customized 3D print materials, both of which are infused with anti-cancer drugs. These bone substitutes could be used to fill and stabilize the large empty spaces and to locally deliver anti-cancer drugs that kills any remaining tumor cells and promote […]

Sound pressure level in aircraft cabin are similar to a noisy work place. One of the most disturbing noise for passengers is related to the engine fan noise during take-off and approach. This noise is mainly tonal (i.e., at specific frequencies) and in the low frequency range (below 500 Hz) – see figure below. Reducing […]

There has been an extensive growth in additive manufacturing, 3D printing, over the past couple of years. At the moment, pure polymers are mainly used for manufacturing parts and they yield low strength and stiffness, not suitable for load-bearing products. The use of carbon fiber composites in 3D printing can significantly improve structural properties. Currently, […]

To maximize usage of residuals and underutilized product streams at Port Hawkesbury Paper (PHP), this investigation is conducted with eco-industrial parks in mind, and a goal of increasing industrial sustainability. The streams investigated could act as a supplement to PHP’s current processes or an external feedstock for a collaborative relationship through waste as a form […]

Smart wearable biomedical technology has a wide range of application in health monitoring during life activities or in traumatic situations. This technology can provide a practical and convenient solution for continuous health monitoring of elderlies, and patients suffering from different types of dementia like Alzheimer’s Disease. Additionally, the technology can facilitate trauma medicine by providing […]
