Natural Canadian zeolite is an attractive mineral for the restoration of lands disturbed by the extraction of natural resources such as metals, oil and gas. Dr. Wonjae Chang’s Environmental Engineering Lab developed a dualmineral prototype, using Canadian zeolites, for the desalination of potash brine-impacted water. Dr. Chang also demonstrated the significant accumulation of residual potassium […]

Modern electric power systems are rapidly adopting renewable energy resources. This positive movement, however, does bring with it major challenges to the way we operate power systems. In particular we may face drastic frequency changes and far-reaching transient phenomena. One way to remedy these is to deploy energy storage systems, such a s batteries, to […]

This project aims to design new highly compact and highly effective filters for a multi-level power converter based on wide-bandgap (WBG) transistors that integrates an Active Front Ends on the grid-side. Leveraging the high switching speed of WBG, new light weight multi-stage filters suppressing all switching frequency are designed for both the utility and motor […]

The proposed project mainly focuses on developing an innovative gas/liquid contacting technology that is of critical importance to a wide range of process industries and environmental-management operations. Successful development and implementation of this project are expected to: ? Reduce the environmental impact of a variety of operations that are needed to meet human needs and […]

The emerging 360-degree video applications provide the user with an immersive experience. This comes at the price of high computational complexity to process the high-resolution content (e.g. 4K or 8K) and of high data rate to deliver it in real time to the user. The user’s experience can be made more realistic using stereoscopic 360-degree […]

Constructed wetland is a critical water infrastructure in major Canadian cities like the city of Edmonton, which treats wastewater including storm water by reducing the suspended solids and the related contaminants before entering into receiving waterbody. The design and evaluating the performance of a constructed wetland requires accurate prediction of flow fields and particle pollutants […]

The Samson Cree Nation, near Hobbema, Alberta, relies on groundwater aquifers for its water. In the Samson Nation faced worsening water quality that has resulted in the issue of more than 65 boil-water advisories to residences, affecting almost ten percent of the wells on the The source of the problem is unclear, and residents are […]

The treatment of chronic conditions accounted for 58% of the annual healthcare spend in Canada in 2012, primarily through the use of pharmaceuticals. However, these are generally best suited to treat acute diseases, as with chronic use, side effects can accumulate over time while therapeutic effects diminish. Neuromodulation of the Peripheral Nervous System (PNS) represents […]

The Windsor Lake drinking water treatment plant (WLWTP) in St. John’s Newfoundland is a microfiltration (MF) membrane plant. One shortcoming of membrane filtration is a phenomena called fouling; fouling refers to the build up of rejected particles on the surface or into the membrane’s pores that can negatively affect the membrane’s performance. Since it’s installment, […]

MicroLED displays are of growing interest and are seen as a next generation display technology for leading-edge displays of all sizes, from head-mounted displays for virtual reality through portables (watches and cell phones) to televisions and wall-size displays. Red, green and blue light emission from blue-emitting Light Emitting Diodes (LEDs) would replace the use of […]

As transportation to space becomes more accessible, space debris pose increasing risk to operational satellites. Objects orbiting the earth can have a detrimental effect on space travel and threaten the spacecraft and its personnel. These objects can be anything from active and passive satellites, orbital debris, space junk, asteroids and fragments from their disintegration and […]

Liver cancer is the fifth most common cancer and has the third highest death rate world-wide. Patients are usually diagnosed once the disease has progressed to a point where a cure is not possible. An emerging treatment to help manage this type of cancer uses small particles to block blood from reaching the cancer while […]
