Lithium-ion batteries are increasingly being used to reduce fossil fuel use and emissions. Cold weather performance of Lithium-ion batteries is a limiting factor in outdoor applications. Mavio Technologies Inc. aspires to construct durable Canadian made Lithium-ion batteries packs that perform well in the adverse Canadian climate. This project plans to research the effect of using insulation to increase cold weather performance.
SARS-CoV-2, the virus responsible for the current COVID-19 pandemic, displays a coronashaped layer of spikes which play fundamental role in the infection process. Recent structural data suggest that the spikes possess orientational freedom and the ribonucleoproteins segregate into basketlike structures. How these structural features regulate the dynamic and mechanical behavior of the native virion, however, remain unknown.
Structural integrity assessments play a key role in ensuring the safe service of oil/gas pipelines. In recent years, significant developments in pipeline strain-based design have taken place to account for the large plasticity involved in the installation and operation of pipelines. However, current methodologies cannot properly address the effects of anisotropic material properties and weldments on the behaviours of defects in pipelines. It is proposed here to develop fracture mechanics methodologies that quantify these effects. Both global and local approaches will be used in the study.
Commercial MagnetoRheological (MR) dampers are still bulky and consume relatively high power. Thus new designs to improve their energy consumption and total mass are required so that they can be used in applications such as prosthetics and small electric vehicles that are restricted by energy consumption and mass. To address the above issues, in this research we focus on the design of a MagnetoRheological damper to achieve small mass with low energy consumption for commercial use.
Theft or loss of sensitive data is a growing concern for companies who may suffer losses of consumer confidence, market valuation and intellectual property when large amounts of data are stolen. In this research project we will use an enhanced “screen and review” approach to combating exfiltration in a large data set of activity logs within a large corporate network.
Catalyst layers (CLs) determine the performance, durability, and cost of PEM fuel cells. The proposed research will focus on developing durable ultra-low-Pt-loading CLs with high performance and durability. The novel CLs will be fabricated by sputtering Pt onto a thin layer of carbon particles, pre-deposited on the membrane. The CL structure will be investigated by SEM, TEM, and the method of standard porosimetry. Electrochemical and mass transport properties will be characterized by cyclic voltammetry, electrochemical impedance spectroscopy, and Loschmidt Cell.
Lubricant is the substance used to decrease the friction generated between the two surfaces undergo relative motion. There are many applications for naturally occurring lubricants in medical field to improve a patient’s quality of life. Fucoidan is one of the naturally occurring lubricants that has the potential of reducing adhesion after an abdominal surgery. ARC Medical devices have developed an advanced manufacturing process to produce ultra-pure fucoidan that’s more suitable for clinical application.
Light and heat have been used to manufacture objects layer by layer in additive manufacturing technologies. In this project, sound is used to create object by interacting with build material. Wide range of material such polymer, composites, glass, ceramic and metal can be manufactured and the produced part has functional properties. The project introduces an alternative route for creating objects and opens new doors for future research. The outcome of the project is used to create a new class of manufacturing machines that can create jobs and intellectual property to Canada.
Reducing fossil fuel use in transportation and utility scale electricity sectors is required to meaningfully reduce anthropogenic carbon emissions and to improve air quality in urban and industrial centres. Lithium ion batteries are beginning replace combustion engines for transportation applications, and show promise as tools that allow power utilities to seamlessly integrate intermittent carbon-free energy sources (i.e. windmills and solar panels) into the electricity grid.
The liquid accelerated cold spray (LACS) technology is an innovative process that uses a high-pressure liquid flow to accelerate metal and composite powders to very high velocities (above 500 m/s) so that, upon the impact on the substrate, they form a coating. Using a liquid instead of a gas as used in a traditional cold spray, makes it possible to spray particles with a larger size distribution owing to the high density of the liquid.
