Ce projet portant sur le développement de fibres optiques moyen-infrarouge pour l’amplification laser s’appuie sur des compositions de verres à base d’oxydes lourds dopées avec des ions luminescents tels que des terre-rares. En effet grâce à l’emploi d’oxydes lourds, l’énergie de phonons du verre est abaissé permettant une exaltation des phénomènes de luminescence rendant intrinsèquement […]

This research aims to generate and optimize optimal tool-path(process path of robot) by learning data on kinematics and dynamics properties required for the machining process using multi-axis robots with Artificial Intelligence(AI). Based on the end-effector of the robot, a new approach is proposed to optimize tool path in drilling or milling processes and to develop […]

Bio-materials can reduce our dependence on fossil fuels, greenhouse gas emissions and facilitate a rapid transition to a bio-based leconomy. Thus, developing novel and innovative technologies and products related to bio-materials sectors is crucial. This has !resulted in extensive research into the development of biomaterials. Most research efforts have focused on materials selection, ‘fabrication, and […]

This is a partnership between ABB, an international leader in water quality monitoring, and McGill University, where the objective is to test the reliability of an emerging technology in ion concentration measurement. The technology combines state-of-the-art electronics, composed of the atomically thin material graphene, and ionsensitive polymers, developed in the research group of Prof. Szkopek […]

The biggest challenge faced by structural engineers in the design of high-rise structures is to control the dynamic responses of these structures due to wind and earthquake vibrations. While the traditional techniques of stiffening and adding vibration absorbers can mitigate the vibrational response to a degree, they also increase the construction cost and result in […]

Gallium nitride (GaN) high-electron-mobility transistors (HEMTs) are good candidates to replace the traditional silicon-based transistors. Although these devices show superior performances compared to Si and SiC-based devices, they suffer from some reliability issues. The aim of this research project is to improve the performance of the GaN HEMTs and enhance their reliability by performing a […]

The milling process is an industrial manufacturing method commonly used for shaping custom parts with precise tolerances using rotary cutters. Rough Milling processes affect the part quality of machined components due to high temperature, large strain, and high strain rate. It is important to identify and improve the milling-induced residual stresses of surface and subsurface […]

As Lowe’s Companies Incorporated expands their organization across Canada they face tough decisions about where to locate new retail stores. These decisions take place at different scales and require choices to be made about what towns or cities would benefit from a new home improvement center and where within these towns or cities the center […]

The Canadian Light Source produces a very bright light which can be used to study DNA, viruses, cells, proteins, and other small-scale structures. To generate this light, the CLS needs a beam of electrons which are generated by an electron gun. In 2018, this electron gun failed, and the facility was unable to function for […]

Most rubber products require curing that involves either sulfur or peroxide curing and other ingredients such as accelerators, antioxidants, antiozonants, and heavy metal oxides. Some of these ingredients, either individually or in combination, generate environmental pollutant and hazardous gases and fumes during rubber processing or storage. Thus, there is a continuous need by the rubber […]

The requirement for online communication continues to grow exponentially, primarily a result of the increased demand for information sharing bandwidth. This demand is driven by video-over-internet applications used for both entertainment, and conferencing (felt most recently in the need for remote working during the COVID-19 pandemic). Integrated optical components fabricated in silicon are receiving particular […]

Newly developed additive manufacturing (AM) techniques, also known as 3D-printing, are able to fabricate complex geometry components at a relatively high deposition rate, the lowest possible number of production cycles, and minimum materials waste in contrast with the conventional subtractive fabrication techniques. By drastic reduction in the fabrication time and production steps, minimizing the on-hold […]
