Identifying the sources of aerosol ammonium is essential because ammonium can impact the Earth’s radiative balance, as well as human health and biological diversity. The sources of ambient ammonia concentrations can be quantified based on the stable isotopic composition of ammonia for various endmembers. However, isotopic source apportionment of aerosol ammonium is challenging in the urban atmosphere, where there is excess ammonia and nitrogen isotopic fractionation commonly occurs.

Providing education and access to services for remote communities is a daunting task. Not all communities have the same opportunities, but the University of Saskatchewan has faculty and alumni who work on a daily basis to reduce the inequity between the north and the south.

University of Waterloo chemists have found a much faster and more efficient way to store and process information by expanding the limitations of how the flow of electricity can be used and managed.
