Development of a Process for Manufacturing Synthetic Hydrocarbon Fuel from Captured Carbon Dioxide

This project would seek to develop an integrated system incorporating a reverse water gas shift (RWGS) reactor to convert carbon dioxide and hydrogen into carbon monoxide and water, aiming for maximum production of carbon monoxide. RWGS is an endothermic, catalytic, equilibrium-limited reaction, so the project team will seek to develop efficient, novel catalysts and supports, an optimal reactor design, and an efficient separation/recycling system so as to minimize wastage of unreacted raw materials. The work would build on and incorporate results from previous and ongoing funded projects in this area. High quality carbon monoxide is a very valuable industrial chemical, and can be used to manufacture products including liquid transportation fuel that is fungible to users of current conventional petroleum based fuels. The use of carbon dioxide, which is currently regarded as a problematic waste product of major industries like power generation, as a raw material for RWGS could represent a novel economic opportunity for large emitters.

Modélisation géospatiale du Port de Montréal: vers un jumeau numérique

Le fleuve Saint-Laurent est essentiel pour le développement économique du Québec, car il sert de route principale pour le transport de marchandises et d’entrée en Amérique du Nord. Compte tenu de son intense activité, le Saint-Laurent a été choisi comme site pilote pour tester une nouvelle norme internationale, la norme S-100 de l’Organisation Hydrographique Internationale (OHI). Cette norme vise à uniformiser les produits et services maritimes en intégrant différentes données nautiques numériques.
L’objectif du projet est de créer une modélisation en 3D du Port de Montréal, le plus grand port du Québec en termes de tonnage. Cette modélisation s’inscrit dans un effort plus large de création d’un modèle servant d’inspiration pour un futur « jumeau numérique » du port, c’est-à-dire une maquette numérique qui respecte la norme S-100. Cependant, la réalisation de cette modélisation 3D pose des défis importants. Il s’agit de rassembler et d’intégrer des données géospatiales et hydrospatiales de haute qualité pour garantir une modélisation détaillée du port. Ces données sont souvent géoréférencées dans différents systèmes de coordonnées avec une grande hétérogénéité de résolution spatial et qualité.

AI-driven XRD spectra interpretation and classification

This project aims to develop an advanced system for interpreting X-ray diffraction (XRD) data and classifying it based on insights provided by Subject Matter Experts (SMEs). XRD is a critical analytical technique used across various industries, including materials science, geology, and geophysics, to determine the crystallographic structure of materials. However, the raw spectra generated from XRD analysis are often complex and require expert interpretation to derive meaningful conclusions.

Materials Formulation Generation Using A Novel Informatics Platform

Materia is addressing this challenge with an AI/ML-driven materials informatics platform with an integrated marketplace, empowering companies to develop and launch eco-friendly products 65% faster and cheaper. This project will help Materia to expand its capabilities through the development of a data driven algorithm that can specifically assist customers from material selection to formulation, the first steps in product development.

Impact of environmental stimuli on electrical responses in plants

Research in our group has begun to show that plants generate and use electrical signals to control functions within their
structure. When external stimuli are applied to a plant, different electrical signals are generated. These electrical signals contain
information both about the stimuli but also how the plant reacts to this stimuli. This research project’s goal is to measure these
electrical signals under different stimuli, and attempt to interpret and understand how these signals are generated and how the
plant uses these signals. Our earlier research has developed equipment and computer monitoring systems for these plant
electrical signals. These signals are recorded with custom built electrodes and the signals are decoded to predict the type of
stimuli that was presented to the plant. Our research will assess the electrical signal with two different plant species and
compare the results under different environmental stimuli. This research will allow us to begin to understand how these
electrical signals can be used by researchers to understand the inner workings of plants.

Development of rapid and accurate genomic techniques for ballast water UV treatment

The United States Coast Guard (USCG) recently introduced stringent regulations for the treatment of ballast water. Ultra-violet (UV) light is a useful technology in a ballast water treatment system (BWTS), for inactivating phytoplankton which could be invasive and harmful to humans and the environment. UV damages DNA and prevents replication, but the vital stain methods mandated in the USCG protocol do not detect UV damage. Alternative culture-based measures of reproductive capacity are yet to be approved, time consuming, and have limitations (not all species may grow). Rapid and accurate assays to identify cells that are UV damaged beyond recovery are critical for the acceptance of UV-based BWTSs. We will use DNA damage and repair gene activity assays to develop a rapid, reliable and cost effective quantification method for UV algal elimination in ship ballast discharge. TROJAN Technologies will use this technology to validate UV sterilization for global ballast water treatment.

Ex Vivo Live Imaging of Hematopoietic Stem Cells in D. melanogaster

This project aims to investigate asymmetric cell division (ACD) in blood cell development using live imaging and Drosophila melanogaster (fruit fly) as a model system. Hematopoiesis, the process of blood cell formation, relies on tightly regulated mechanisms to balance stem cell self-renewal and differentiation. Disruptions in this balance can cause blood disorders such as leukemia. ACD, where a stem cell divides to produce one self-renewing and one differentiating daughter cell, is a key mechanism for maintaining this balance, but its role in mammalian hematopoiesis remains poorly understood due to technical challenges in live imaging. This project will combine advanced live imaging techniques with genetic tools for tracking ACD-associated proteins in the Drosophila lymph gland, a hematopoietic organ. By visualizing how cell polarity proteins like Par-6 dynamically influence ACD and blood cell fate in real-time, the study aims to provide insights into how environmental signals regulate blood cell development and identify potential therapeutic targets for blood disorders.

Study to increase production efficiency in a lumber recycling process

This project promotes the use of recycled material by diverting it from current waste streams, thus reducing the pressures on local landfills and positively contributing to a reduction in greenhouse gas emissions. However, processing lumber waste generated in construction and demolition projects remains challenging due to the variability in dimensions and wood species as well as the presence of contaminants (e.g., coatings and preservatives) and impurities (e.g., nails and screws). As such, the goal of the project is to collect extensive data on the manufacturing process to study material flow and quantify the efficiency of each processing step in order to identify areas of improvements. The intern will then design novel solutions to significantly increase process efficiency. These solutions will be tested at a small-scale before selecting the best ones that will be implemented. The partner organization will benefit from the knowledge gained from the thorough data analysis and the implementation of novel solutions that will improve its efficiency and support its mission.

Full Scale Biological Filters: assessing backwash performance on microbial and organic carbon outcomes

The City of Ottawa operates two water treatment plants, Britannia and Lemieux Island Water Purification Plants. Their treatment consists of coagulation with alum, filtration and post-filter disinfection. The City operates its filters within a “biofiltration” framework intended to allow for the beneficial growth of friendly bacteria on the filter media surface. Biofiltration enhances removal of organics in the water system that may otherwise contribute to disinfection by-product formation. To allow filters to operate properly, filters are cleaned via a backwash step at regular time periods to clean and maintain the proper function of filters. This research aims to assess various methodologies to evaluate the health of filtration systems coupled with backwash operation. Due to plant maintenance, the Lemieux filter backwashing was supplemented with a chlorine wash. This project aims to evaluate whether a chlorinated backwash affects the organic removal performance at Lemieux WTP, investigate the presence and changes in the microbial population within the biofilter systems, and assess recovery times after transitioning from a chlorinated backwash to a standard water wash. This full-scale research study aims to provide valuable insights for the optimization of filtration systems and map out changes to microbial populations with chlorinated and un-chlorinated backwashes.

Numerical modeling of lean, premixed, pressurised hydrogen flames using large eddy simulation

Blending methane with hydrogen for power generation is well-known to significantly lower carbon-based emissions. However, studies have shown that implementing hydrogen is not trivial. In gas turbine combustion systems, major modifications may be required to facilitate the safe combustion of hydrogen and these modifications depend on numerical modeling.

Turbulent combustion modeling can strongly accelerate the time to implement decarbonised technology but industrial practices are typically validated and optimised for natural gas burning, These require thorough checks to ensure they can be used to model hydrogen-specific phenomena. For example, Hydrogen’s mass diffusion occurs at a higher rate relative to thermal (heat) diffusion, leading to flame instabilities at lean conditions. Pressure exacerbates these but research is scarce at gas turbine-relevant conditions.

This project will explore the usage of industrial models to investigate H2 flame dynamics under pressure. By comparing with publicly-available experimental data, modifications will be introduced to these models. The main objective of this project is to identify the limits of modeling hydrogen by current industrial methods, and then assess newer strategies that incorporate hydrogen physics more explicitly. This will result in clear recommendations for changes to industrial practices and enable the development of future injector technology.

Formalisation d’arguments de sécurité

S’inscrivant dans la continuité du premier stage, ce projet vise à unifier les langages de description de structures argumentatives GSN et TCL et à adapter la théorie de Dempster-Shafer au langage unifié. Cette théorie est la plus adéquate pour intégrer à une structure argumentative les évaluations de ses noeuds. Notre objectif est d’arriver à déterminer de bonnes règles servant à propager avec précision les évaluations des noeuds enfants vers le noeud racine. Le résultat des modèles d’inférence est très important pour l’entreprise partenaire, car l’interprétation de ces modèles en termes d’analyse de risques donne lieu à d’importantes prises de décisions. Ce travail aboutira à une meilleure définition des méthodes d’interprétation de structures argumentatives.
