New research is showing that some tiny catalysts being considered for industrial-scaled environmental remediation efforts may be unstable during operation.

Chemists from the University of Waterloo studied the structures of complex catalysts known as “nanoscale electrocatalysts” and found that they are not as stable as scientists once thought. When electricity flows through them during use, the atoms may rearrange. In some cases, the researchers found, electrocatalysts degrade completely.

As we continue to navigate the COVID-19 pandemic, virtual learning has necessarily become an integral part of the day-to-day life of students, faculty, and staff at the University of Waterloo. One of the challenges often associated with online learning is creating active engagements between students and instructors, especially with hands on learning opportunities such as with labs.
