Current Heavy Rare Earth Element (HREE) processing techniques are expensive, environmentally-challenging, and slow. Kinetic models predict that the rate of acid permeation of a mineral is the rate controlling step. Therefore, permeation rate controls the acid quantity and residency time of the mineral in the acid bath; impacting costs. Kinetic models are based on structural assumptions including the uniform distribution of elements within a mineral. This study proposes to employ atom probe tomography on the HREE-mineral gadolinite: an ore mineral in the resource at Strange Lake, Quebec.
Cellulose is a commercially important biopolymer. Due to its abundance, biocompatibility and renewability it has shown important commercial applications in food, pharmaceuticals, biomedical. Depending on the origin and the processing methods used, the resulting fiber dimensions, structure, crystallinity and molecular weight (MW) can vary over a broad range. MW is one of the most important parameters in polymer characterization as many of its properties depend on it. Gel permeation chromatography (GPC) has been the technique of choice for determining these properties.
This proposed project focuses on American ginseng (AmG), a natural herb native to Canada that has been used as a traditional medicine for many generations. Southern Ontario has become the Worlds largest producer of AmG with annual sales of over $400M at the farm gate. Polysaccharides (PS) are a major active component of AmG showing various biological activities including anti-carcinogenic, anti-aging, immunostimulatory and antioxidant effects.
This research project will focus on analytical techniques related to determining the gold geochemistry of the La Victoria property in the western Peruvian Andes. The La Victoria property is found along a major gold belt that is host to some world class deposits such as Yanacocha, Lagunas Norte, La Arena and Shahuindo. Based on initial exploration techniques, two major mineralized areas (San Markito and Rufina) have been identified as important for gold exploration.
Global population growth, urbanization and changing climate patterns have increased the demand for potable water, wastewater reuse and value recovery from wastewater, and treatment of industrial process water. Population growth also results in increased demand for the shipping of goods by ocean freight, with the associated risk of the transport of unwanted marine life from one location to another by the discharge of ballast water.
PACICC role is to compensate policyholders in scenarios where a P&C insurer can no longer provide compensation while overseeing the health of the P&C industry in Canada. The proposed project aims to improve PACICC’s ability to identity companies at risk of insolvency and improve strategies to minimize dead weight loss when insolvency is imminent.
Electronic exchanges are venues that provide immediacy for those who need to find a counterparty to their trades. Orders of various types arrive in the market at ever increasing speeds, and in this era of high-frequency trading (HFT), institutional investors are often disadvantaged because of their high-latency relative to faster traders.
Risk aggregation is omnipresent in insurance applications. A recent example, borrowed from the modern regulatory accords, is the determination of the aggregate economic capital and its consequent allocation to risk drivers. A more traditional illustration of the importance of risk aggregation in insurance is the celebrated collective risk theory that dates back to the early years of the 20th century. This project will assist Sun Life Financial to build and implement an efficient quantitative framework to approximate the aggregate risk of its portfolio.
The main objective of the project is to develop hybrid distributed energy resource (HDER) systems to supply energy to net-zero energy commercial and residential buildings. This is expected to result in lower energy costs to consumers and utilities and in greater reliability of the grid. The HDERs will consist of solar panels, generators, and batteries. They will supply buildings with energy whenever possible and feed any excess energy to the grid. The grid will supply energy to the buildings whenever energy from the HDERs is insufficient.
Advanced batteries are critical for achieving high-performance electric vehicles (EVs) and supporting goals to reduce greenhouse gas emissions. The prevailing rechargeable Lithium-ion batteries (LIBs) using liquid electrolytes, are the major choice for current EVs. However, these LIBs still suffer from safety, lifespan, and energy density issues.
