A new study shows that smoke from wildfires destroys the ozone layer. Researchers caution that if major fires become more frequent with a changing climate, more damaging ultraviolet radiation from the sun will reach the ground.

Atmospheric chemists from the University of Waterloo found that smoke from the Australian wildfires of 2019 and 2020 destroyed atmospheric ozone in the Southern Hemisphere for months. The ozone shield is a part of the stratosphere layer of the Earth’s atmosphere that absorbs UV rays from the sun. 

Atoms and molecules are the building blocks of chemistry and are important to our understanding of the world. By cooling atoms and molecules to ultracold temperatures it opens up a new understanding of quantum chemistry. Working with nanokelvin temperatures, one billion times colder than Antarctica during winter, researchers can observe and control particles in ways not possible at room temperature. When really cold, particles behave in strange and exciting ways. Researchers are discovering unexpected results by looking at particles from a quantum perspective.

Professor Sherry Schiff from the Department of Earth and Environmental Sciences has been awarded the 2022 Frank Rigler Award, the highest honour given by the Society of Canadian Limnologists.

A study of more than 2,000 streams around North America found that those altered by human activity are at greater risk of flooding.

The study from the University of Waterloo analyzed the seasonal flow patterns of 2,272 streams in Canada and the U.S. and found that human-managed streams – those impacted by developments like dams, canals, or heavy urbanization – had significantly different flow patterns compared to streams in natural watersheds.

Congratulations to Professor Linda Nazar , who was awarded the 2022 E.W.R. Steacie Award by the Chemical Institute of Canada. The award is presented to “a scientist who has made a distinguished contribution to chemistry while working in Canada."

Professor Scott Hopkins has been named the winner of the 2022 Keith Laidler Award for his outstanding early-career contributions to physical chemistry in Canada.

Decisions about COVID-19 vaccinations often come down to trust.

Trust in peer networks, in the information available to a person and in the health-care system as a whole.

Congratulations to Professor Jozef Nissimov from the Department of Biology who has been awarded John R. Evans Leaders research infrastructure funding from the Government of Canada through the Canada Foundation for Innovation (CFI).

In the quest for the perfect battery, scientists have two primary goals: create a device that can store a great deal of energy and do it safely. Many batteries contain liquid electrolytes, which are potentially flammable.

As a result, solid-state lithium-ion batteries, which consist of entirely solid components, have become increasingly attractive to scientists because they offer an enticing combination of higher safety and increased energy density — which is how much energy the battery can store for a given volume.

Eugenia Dadzie, a master’s student from the Department of Biology, won first place in Graduate Studies and Postdoctoral Affairs (GSPA)’s GRADflix showcase for her video Microbes and enzymes: sustainable plastic degradation, describing her research into finding microbes that can break down plastics in the environment.
