Air pollutant emissions from the oil sands and impact on the local First Nations community: Fort McKay
Faculty advisor: Professor Jeffrey Brook
The Canada-Alberta Oil Sands Monitoring Program (OSM) operates a heavily instrumented atmospheric monitoring site in Fort McKay, a First Nations community surrounded by the oil sands development. Many pollutants are being measured with high time resolution, including some measures in the vertical and space-based measurements from satellites. Hydrocarbons, nitrogen oxides, fine particulate matter, dust and odours are notably critical air quality issues. A large, publicly-available dataset is available which represents an important opportunity to improve understanding of how the oil sands is impacting the community, its people and its environment, and to apply a range of data analysis techniques.
Research projects of interest will harness novel data mining techniques to learn more about what aspects of the oil sands activities are responsible, when and why they occur (e.g., meteorology) and potentially which industries are responsible.

Analysis of liquid and solid samples from a pulp and paper mill
Looking for an MEng student to analyze liquid and solid samples from a pulp and paper mill, specifically focusing on wood extractives and sulfur compounds. The aim of this project is to uncover the underlying processes behind the formation of organic deposits within the black liquor evaporation system at a collaborating pulp and paper mill in New Brunswick. These deposits have consistently posed a challenge across multiple mills, leading to significant equipment downtime and revenue loss.
The chosen student will have the opportunity to visit the mill and gain insight into the operational procedures and machinery. Cutting-edge analysis techniques, such as Pyrolysis-GC/MS, LC/MS, ICP, and/or MALDI-TOF-MS, will be employed for the investigation. Analyses will be implemented by the student within our labs, or by other UofT labs. Furthermore, the student will be tasked with integrating the outcomes from all analyses into a cohesive understanding.
Knowledge about organic chemistry and experience with any of the aforementioned techniques is an asset but not a requirement. The ideal MEng candidate is meticulous and committed to producing repeatable and publishable data.
The project duration is flexible, but an immediate start date is preferred.

Biochar as a tool for alleviating climate change
Trees are crucial to humankind's survival, releasing the oxygen we breathe, growing the fruits we eat, and supplying wood to build and warm our shelters. Heating wood at high temperatures with little or no oxygen creates wood biochar, a carbonaceous product. Wood biochar monoliths have a continuous carbon matrix and morphological features that resemble anatomical elements in a tree, including xylem and phloem, which transport water from the root and deliver sugars from leaves to individual cells. Structurally and chemically, monolithic wood biochar belongs to nanoporous carbons (NPCs) consisting of carbon nanotubes arrays and integrated graphene sheets. Researchers have extensively explored NPCs as functional materials for applications essential to sustainability, including electrical energy storage, water purification, and CO2 capture. However, the lack of scalable manufacturing technology continues to hinder the large-scale utilization of NPCs despite their demonstrated superiority in enhancing materials performance. Derived from abundant woody biomass with simple processes, wood biochar offers a new opportunity for overcoming this limitation. Focusing on electrical energy storage and water purification, the Green Technology Lab at the University of Toronto explores wood biochar’s potential in areas critical to sustainability and develops wood biochar into a greener, more cost-effective, and scalable nanoporous functional material.

The “Leaky Pipeline” Effect in Higher Education: Attrition in Underrepresented Graduate Students in the STEM field
The term “leaky pipeline” refers to a phenomenon where there is a disproportionate attrition, of women (including minority women) as they progress in their careers in fields such as Science, Technology, Engineering and Mathematics (STEM). Historically, women are under-represented in doctoral programs and faculty positions, and the disparity becomes even more obvious at higher-level faculty positions. Reportedly, this trend is more pronounced in STEM fields. The Canadian Science Policy Centre (CSPC) reported in May 2022 that women only represent 12% of full-time STEM professorships in Canada and an even smaller percentage are found at higher-level faculty positions. Blacks and other minority races are also disproportionately underrepresented in higher-level positions in STEM academia. In a previous study by Figueiredo (2023) in which the intersectionality of being female and belonging to the Black or other minority races was considered, an even greater disparity was observed as progress was made along the academic pipeline.
This study aims to identify the key stressors that might contribute to the “leaky pipeline” effect for first-generation female immigrant doctoral students who self-identify as black or other ethnic minority groups as they progress in their academic careers. The effect of different stressors on the willingness to continue in academia will be evaluated using a mixed-method research, mata-analysis approach, interviews and surveys. The project will also deploy data analytics approaches to process the large dataset and find unique patterns in this study.

Extraction of Rare Earth Elements from Ionic Clays
Faculty advisor: Professor Vladimiros Papangelakis
Aqueous Process Engineering and Chemistry Group
Department of Chemical Engineering and Applied Chemistry
Rare earth elements (REE) are critical commodities with high accessibility risk due to monopolistic practices of suppliers and increased demand. The development of green and hi-tech applications such as clean energy and advanced catalysis created ongoing requirements for REE in the international markets, with an emphasis on identifying new resources to ensure adequate supply and access.
The present project investigates the use of ionic clay ores as an economical source for REE. Rare earth ions are physically adsorbed on clay minerals, with concentrations ranging from 0.05 to 0.5 wt.%, and can be easily recovered under mild, ambient conditions via ion-exchange leaching with monovalent salt solutions (such as ammonium sulphate or sodium chloride). This project is of high interest for the mining industry, as it addresses the recovery aspect of REE from ores, as well as the processing industry, as it provides an additional REE supply alternative.
A standardized desorption procedure will be established to systematically investigate the influence of leaching conditions such as lixiviant type, concentration and pH on desorption kinetics and REE extraction levels, aiming to identify the optimum conditions that achieve maximum REE recovery.
The MEng student will be tasked with performing the leaching experiments under various conditions and have the opportunity to be trained in Inductively-Coupled Plasma Optical Emission Spectroscopy (ICP-OES) analytical technique. Furthermore, the student will be tasked with integrating the outcomes from all analyses into a cohesive understanding, by processing and plotting data, discussing/comparing trends and findings, and preparing presentations. The prospective student will work closely with Dr. Georgiana Moldoveanu, who will provide training and ongoing support.
Knowledge about aqueous chemistry and previous laboratory experience are an asset but not a requirement. The ideal MEng candidate is meticulous and committed to producing repeatable and publishable data. The project is going, so the student is welcomed to join at the moment

Green and solvent free polymeric membrane fabrication for harsh chemical separation settings
Faculty advisor: Professor Ramin Farnood
Ultrafiltration techniques (UF) play a crucial role in various industries such as water and wastewater treatment, dairy, and food processing. However, the conventional approach to manufacturing ultrafiltration membranes through phase inversion techniques has proven unsustainable due to the use of toxic solvents like DMF and NMP, leading to the generation of organic wastewater.
In response to these challenges, membrane research is now trending towards the development of solvent-free membranes fabrication. These innovative membranes utilize aqueous soluble polymers that solidify upon a chemical trigger, significantly reducing the environmental impact by eliminating the need for toxic organic solvents.
The primary objective of this research project is to create a green phase inversion fluoropolymer membrane with outstanding flux rates and selectivity. Through subsequent post-modification processes, the aim is to produce a polymeric membrane that is not only chemically and thermally stable but also capable of withstanding severe chemical separation environments.
Students participating in this project will acquire expertise in various areas, including membrane fabrication, surface and material characterization using techniques such as SEM and EDS, tensile testing, and standard separation testing. These skills are essential for contributing to advancements in membrane technology while aligning with sustainable and environmentally friendly practices.

Multifunctional sensors array for smart skin applications
Human skin is the largest sensory organ in our bodies allowing us to safely maneuver within our surrounding environment. This physical barrier which enables us to interact with our physical world comprises several sense receptors through which information from a physical contact transduces into electrical signals. An artificial skin, also referred to as smart skin or electronic skin (e-skin), with human-like sensory capabilities can make a significant impact on the autonomous artificial intelligence as well as smart wearables. This can be achieved by providing a sensory perception even better than their tradional counterparts. In addition to force sensing as the primary function of human skin, other functionalities such as mechanical/electrical/thermal along with flexibility/stretchability are of great importance to be considered in an e-skin. The project will investigate the design and fabrication of a pressure sensor mimicking the main characteristics of natural skin, potential of using conducting and nanomaterials as piezoresistive sensors for electronic skin applications.

Plastic waste and biowaste pyrolysis
Faculty advisors: Professor Donald Kirk
The world is facing a number of challenges in the sustainable energy field. Managing GHG emissions as well as wastes are often at odds. A belated realization that plastics do not degrade easily has added to the waste challenges. It is clear that some form of permanent sequestration of carbon is needed to rebalance CO2 emissions with CO2 bioabsorption. The research is focused on conversion of wastes containing sufficient carbon content to produce sequestrable char as a valuable soil amendment and eliminate the production of CO2 and CH4. Biowastes such as sewage sludge, have a limited lifespan in soil or landfills and hence returns to the carbon cycle. Non-recyclable plastics have a longer degradation time but it is clear that degradation producing micro and nano particulates causes global contamination with uncertain consequences. Therefore the conversion of these wastes to char which can be used to enhance crop growth, prevent fertilizer runoff, retain moisture and provide micronutrients for restoring degraded lands is desperately needed.
The research on conversion of some biowastes to char has been completed and demonstrated on a commercial scale in Ontario. More biowastes still need to be studied. Research on conversion of plastic wastes has just been started.

Projects in Food Engineering
Faculty advisors: Professor Levente Diosady and Dr. Juveria Siddiqui
The Food Engineering Research Group at the Department of Chemical Engineering and Applied Chemistry performs research on food fortification technologies. Double Fortified Salt (DFS) technology of adding iron and iodine to salt was developed at the Food Engineering Lab, UofT. This Double Fortified Salt aims to reduce anemia which is a major contributing factor to the 200,000 annual maternal deaths and more than one million annual infant and neonatal deaths globally. DFS technology is now pilot tested in India and is reaching more than 60 million people.
The following opportunities are for MEng students:
Iron Fortification: Approximately 2 billion people are iron deficient worldwide. This is best addressed through food fortification, which is transparent to the consumer. Fortification requires a carrier that is universally and uniformly consumed by the target population. For poor rural consumers in South Asia salt and tea are the most promising carriers. Unfortunately, both salt and iron salts are reactive, and the technical challenge is to maintain the bioactivity of the added micronutrients.
This project seeks to develop appropriate technology for adding iron and other micronutrients to either tea or salt.
Mustard Protein Processing: Mustard is a drought tolerant Canadian crop now used for condiments. Its protein content is well balanced and could be a useful food ingredient replacing soy proteins in manufactured food products. The oil is not allowed in food in Canada, but is a potential fuel feedstock.

Soy Stearin replacement
Soy stearin replacement in micronutrient premix coatings. Although soy stearin is a stable coating, it can be broken down under certain conditions, releasing the iron core of added premix particles, resulting in the loss of other micronutrients, as well as resulting in unsightly dark spots in the food

Stability of Added Vitamins During Food Preparation
To combat birth defects and maternal mortality, iron and B vitamins can be added to salt. However, it is unknown, whether the added vitamins survive during traditional cooking. We will test the effect of cooking, frying and baking on the retention of B vitamins added through quadruple fortified salt. Analytical techniques including HPLC, ICP and wet chemical methods will be used. The candidate will work directly with a post doctoral fellow and/or senior doctorate students.

TiO2 replacement as colour masking agent
Titanium dioxide replacement as colour masking agent in micronutrient premixes for salt. Titanium dioxide is used as a whitening agent in many foods and drugs. The EU banned titanium dioxide nanoparticles, and it is prudent to look for an alternative before TiO2 is banned widely. We will test a number of coatings for colour and stability.

Wastewater-based surveillance for emerging or seasonal pathogens
This research is part of the wastewater surveillance program initiated by Ontario Ministry of Environment, Conservation and Parks (MECP) to monitor SARS-COV-2, RSV, and influenza in wastewater samples collected in Ontario treatment plants.
Wastewater samples are transported to the U of Toronto lab where they are processed to extract RNA and detect respiratory viruses in the samples using PCR. The data are reported as virus gene copies per mL of wastewater.
Objectives for M.Eng Student:
- Collate and organize large data sets containing wastewater concentrations of respiratory viruses collected over time from three treatment plants in the Toronto area.
- Review quality of data and metadata; correct as necessary.
- Perform statistical and visualization analyses to determine if wastewater monitoring can be an effective early warning system.
- Establish fundamental workflow for data analysis for other wastewater pathogens monitored in the future.
- Understanding the importance of standardized materials in cross-lab comparisons of virus loads in wastewater
- Learn the workflow (wet lab and data analysis) for wastewater surveillance; participate as needed in sample analysis (wet lab work ~2 hours per week)
Requirements and Interests:
- Fluent usage of Excel data analysis and graphical tools.
- Experience coding in R, Python or other data analysis pipelines is an asset (or willingness to self-teach).
- Good communication skills and comfortable working in a team.
- Interested in participating in weekly wet lab work (~2 hours per week).
- Interested in learning various biomolecular platforms: robotic extraction, robotic plate loader, qPCR, as well as the state-of-the-art gene quantification system: the 5-channel digital PCR machine.
- Interested in learning about public health data that is closely related to our daily lives.
