This project aims to develop new high-performance materials that can operate reliably in extreme environments, such as jet engines, nuclear reactors, and the automotive industry. Many modern technologies rely on piezoelectric and ferroelectric materials, which convert mechanical energy into electrical energy and vice versa. However, most of today’s materials lose performance at high temperatures, limiting […]

There is a significant global effort to develop fault-tolerant quantum computers, with a leading strategy being the creation of modular, distributed quantum networks. This approach requires high-fidelity “quantum interconnects” to link individual quantum processors. This project proposes to fabricate and optimize the fundamental component for these interconnects: ultra-low-loss, high-finesse nanofiber optical resonators. This will be […]

The proposed project will explore how our new low-noise microwave oscillator technology can meet real needs in radar and communication systems. We will interview industry experts to understand what performance, environmental reliability, and cost requirements are most important for practical use. At the same time, we will work with manufacturers to see whether our design […]

Monitoring water quality is essential for protecting public health and the environment, yet many harmful pollutants remain difficult and expensive to detect. Among them, phenolic compounds commonly released from industrial activities are persistent, toxic, and often found in Canadian water systems at levels that require advanced laboratory testing. Unfortunately, current sample-preparation methods used to extract […]

L’objectif du projet est de préparer et caractériser des échantillons de P(VDF-TrFE) (80-20) afin d’étudier l’influence des conditions de dépôt sur leurs propriétés fonctionnelles. Les films seront réalisés par spin-coating à partir de solutions polymériques homogènes préparées dans la méthyléthylcétone, filtrées puis déposées sur des substrats de silicium conducteurs. Les paramètres de dépôt (vitesse, concentration) […]

Most technology engages our eyes and ears, rarely our sense of touch. When a phone vibrates or a steering wheel buzzes, the goal is to alert us, not to guide us. Yet in daily life, touch guides our actions. Turning off an alarm in the dark, for example, relies on tactile feedback to find the […]

Ce projet vise à approfondir la compréhension des mécanismes fondamentaux lors du dopage métallique de films de DLC (Diamond-Like Carbon) déposés par PECVD couplé à l’injection d’aérosol, procédé plasma permettant la synthèse de couches minces. Ces films, composés d’un réseau de liaisons carbonées sp² et sp³, présentent une grande dureté, une inertie chimique élevée et […]

This project focuses on the combined quantum computational and experimental investigation of molecular transformation routes in antioxidant systems, specifically BHT-quinone, para-benzoquinone, PAN, and PAN2. These compounds are critical intermediates in the degradation of antioxidants commonly used in lubricants, polymers, and other organic systems exposed to oxidative stress. The study integrates quantum-chemical modeling, including density functional […]

This project develops automated pipelines for processing Raman and UV-Vis spectral data collected during studies of molecular degradation. The focus is on improving reproducibility, accuracy, and efficiency in monitoring antioxidants such as BHT and PAN derivatives. The workflows will perform spectral baseline correction, peak fitting, smoothing, and feature extraction, enabling rapid interpretation of large experimental […]

Considerable scientific research is oriented towards providing answers to the disturbing effects of the impacts of global change. There is a growing need to introduce new methodologies to explore the often very complex and interconnected chemistry of the atmosphere. This research program aims to advance our current mass spectrometry-based studies on halogenated atmospheric pollutants with […]

This project aims to improve how we monitor the condition of lubricating oils used in engines, turbines, and other critical industrial systems. These oils rely on antioxidants to prevent chemical breakdown. When the antioxidants degrade, it can cause equipment damage, costly downtime, and environmental harm. To address this challenge, researchers at Carleton University, in collaboration […]

??Submerged Aquatic Vegetation (SAV) are important in aquatic ecosystems as they represent hotspots of biodiversity and ecosystem functioning. Earth observation technologies (EOT) constitute a cost-effective monitoring tool for environmental variables at large scales but their use in freshwater environmental monitoring remains limited because of the optical complexity of inland waters. This research develops and builds […]
