Preparing Asphaltene-based Carbon Fibres by Electrospinning for Optoelectronic Applications

Currently, most electrodes used for optoelectronic application are coated with metal oxides as a conductive substrate, but are expensive to produce. There have been many studies on finding a cheaper and flexible alternatives such as graphene. Asphaltenes are polyaromatic hydrocarbons defines by their solubility class that has a similar structure to graphene. Asphaltenes are found in crude oil, tar sands and coal, but create several problems in the oil industry and are considered a waste due to its tendency to aggregate.

Electroplated Phosphonate Quaternary Ammonium Antimicrobials for Corrosion, Wear and Antimicrobial Resistant Metal Surfaces

We are proposing to use a rapid, safe and green electroplating process to adhere antimicrobial phosphonate quaternary ammonium materials onto receptive metal surfaces. Pathogenic infections are responsible for approximately 60% of all hospital acquired infections. In order to help stop the spread, high contact surfaces such as bed rails in hospitals, door knobs etc. require surface treatments that provide both corrosion and antimicrobial resistance. Alternatively, these materials may also be helpful in providing these properties to metal implants such as prosthetic hips.

Optimal Design and Performance Analysis of Building Level Microgrids with Battery Energy Storage

In order to accelerate the transition of our electricity system to renewable sources, it is important that buildings participate effectively as distributed generators. However, traditional integration methods for solar energy often add complexity to our electricity system. With the rapidly declining costs of battery systems, building-level microgrids are becoming a viable alternative allowing buildings to generate and use renewable energy locally rather than exporting to the grid, enhancing the resilience of energy supply and improving demand profiles.

Non-Invasive Real-time Glucose-Monitoring Smart Textiles

You may have heard of monitoring heart rate in a smartphone using lasers for measurement. Now think of having the wristband or some other wearable gadget and your health status is monitored in your smartphone or your doctors' cloud. Glucose is one of these parameters that can be measured by this wearable device but the challenge is measuring the concentration of glucose in sweat which is almost 1000 times lower than the glucose in the blood. Our group could measure these ultra-low levels of glucose in synthetized sweat.

Developing fluorescent viability stain compounds and uses for anti-cancer drug screening

Breast cancer is the fourth most frequent cancer in Canada, and affects one in X women during their lifetimes. A variety of different treatments have been tried, some of which damage cellular DNA of the quickly growing cancer cells. High-level DNA damage causes cells to die, and can shrink the tumour and arrest cancer growth. The Sabatinos lab studies how cells deal with DNA damage caused by drugs, and how this impacts their ability to grow and divide. A long-time drug used in cancer chemotherapy is a drug called cis-platinum. Our collaborator, Dr. R.

To the root of the problem: preventing excess copper waste and remediation, by targeted treatment of downy mildew in grape crops

Grapes are an important Canadian crop. Canadian winemaking industries rely on grape growers. However, grape crops are threatened by a mould that causes downy mildew. This disease spreads onto grape leaves and if left untreated can kill much of the plant. The grape fruit becomes covered in a dense carpet of mould tissue, and the crop is spoiled and lost. Not just a Canadian problem, downy mildew has become an agricultural concern for vineyards world-wide. Global warming is expected to make the incidence and impact of downy mildew worse.

Structural and thermal performance of optimum 3D printed parts from continuous carbon fiber-Poly Ether Ether Ketone composites

Additive manufacturing, also called 3D printing, of composites can manufacture final parts with high strength and stiffness. In this project, carbon fiber composites with a high temperature polymer are used for 3D printing. A custom 3D printing head installed on a robotic arm is used for manufacturing. Specimens are 3D printed to evaluate structural and thermal properties of final parts. Automated manufacturing of composites using robotic 3D printing is efficient for fabricating small-scale parts with low volume and can open new opportunities for composites.

Plausible Futures: What economic and labour market trends might the City see over the next 3-5 years?

The project aims to identify the plausible scenarios or outcomes of the Covid-19 pandemic associated with the City of Toronto. It will provide insights into how the pandemic is to impact the labour market and organizational operations in various industrial sectors. These insights will support ongoing efforts to revive the local economy and in developing and planning efforts to deal with what the future impact on the City operations.

Biodegradable Polyurethane Elastomers Comprised of Bio-based Plasticizers

Polyurethane elastomers for consumer applications, are developed with primarily bio-based polyester-polyols, isocyanates and bio-based plasticizers which are specifically tailored to result with the required mechanical, flexibility, and biodegradability characteristics useful for consumer applications, especially for footwear and foam products for furniture and automotive industry.

Collaborative Robot for Vertebral Fusion with a Quality of Fusion Estimation Model

Spinal fixation, the process by which a broken spine is mended, or a deformed spine corrected, can involve the placement of tens of pedicle screws during lengthy surgical operations. With an ageing population the overall demand for these procedures is increasing. Surgeon fatigue is an issue in these procedures and has demonstrated decreased performance. Our focus will be on the researching and developing an automatic surgical system for the purposes of spine screw insertion.
