Efforts to sequester atmospheric carbon in soil require effective monitoring methods. Soil water content confounds the conventional application of infrared absorption. Raman spectroscopy contends well with water, but suffers from the overwhelming fluorescence typically encountered in the analysis of soil samples. Here we propose to combine an modulated two-colour illumination scheme with antiphase lock-in detection […]

Ammonia is a toxic metabolic waste product of marine organisms grown or held in aquaculture tanks. Typically, ammonia is degraded using bacteria grown on filter media, but these bacterial colonies can take weeks to become established, which requires significant planning before seasonal fisheries begin. An alternate electrochemical method for eliminating ammonia could be turned on […]

Sugar alcohols such as Xylitol and Sorbitol are an abundant and renewable carbon resource obtained from plant-generated sugars and starches or – preferably – the breakdown of (hemi-)cellulose into the soluble sugars Xylose and Glucose. Already established industrial processes currently running at > 2 million tons/year allow the facile conversion of these sugar to the […]

Le projet de maîtrise consiste à faire l’essai d’un certain type de lentilles électroniques spécialisées, appelées lentilles à focalisation forte, que sont les lentilles quadripolaires électrostatiques. Ces lentilles sont généralement utilisées dans des appareils analytiques comme les microscopes électroniques, les spectromètres de masses, les accélérateurs de particules qui fonctionnent tous à de très basses pressions. […]

Galaxy clusters are the largest gravitationally bound structures in the Universe, making them perfect laboratories to study galaxy formation and evolution. This evolution is closely influenced by the environment of a galaxy and sometimes, when two galaxies are so close to one another, a merging event unfolds. Such an event leaves long lived fossil records […]

In our proposed research we will be performing numerical simulations of cavitation occurring around mantis shrimp appendages. The simulation results will serve to answer how evolutionary diversification in the species has enabled appendages to selectively cavitate only upon impact, and not during forward rotation, despite the appendage-acceleration being comparable with that of a bullet. Moreover, […]

In a world where animal health and welfare are receiving increasing attention, it is crucial that we understand and support livestock farmers who are under an incredible amount of stress. This research is designed to start a supportive discussion and to collect information on the topic of farmer mental health in the beef and dairy […]

This project aims to develop a method for accurately assessing the enzymatic activity of large libraries of compounds. To do this we will employ computational modeling of small molecules in an ensemble of protein crystal structures. The results of this work will lead to a better understanding of the relationship between docked poses and crystal […]

The Loony is a symbol, recognized by all Canadians. While it looks golden, the Royal Canadian Mint is producing its yellow color with an alloy coating on the coin surface. Yellow bronze is a hard and esthetically pleasing material that can be used as a coating for such coins. Internationally, yellow bronze coatings are predominantly […]

Ce projet consiste à préparer et à caractériser des mélanges polymères capables à la fois d’un transport de charge ionique (polyélectrolyte) et d’un transport de charge électronique (polymère semi-conducteur). Ces mélanges, dont le système modèle sera à base de poly(oxyde d’éthylène) (PEO) et de polythiophène (P3HT), seront imprimés en 3D : l’hypothèse de travail est […]

La biomasse est considérée comme une source disponible et une alternative viable au pétrole. La lignine est actuellement une des formes de biomasse la plus ciblée car elle possède une structure polymérique unique contenant des unités aromatiques. Pour accéder aux motifs aromatiques a faible masse moléculaire, les chimistes ont ciblé la liaison ?-O-4 de la […]

Well-known Canadian montane national parks have undergone a length period of fire suppression activities, which started in the early 20th century. This has resulted in old growth forest stands that are relatively homogeneous in nature, often containing forests that have the same species, age, and structure. In recent years, mountain pine beetle outbreaks have occurred, […]
