Scientists uncover new clues about the climate and health effects of atmospheric particles (November 1, 2022): An international team of researchers led by chemists in the Bertram Research Group has found that particles with two phases can form when different types of SOA mix. This finding could help improve current models that predict SOA climate and health effects (From UBC Science). The original paper was published in Atmospheric Chemistry and Physics.

Wildfire smoke may warm the Earth for longer than we thought (October 20, 2022): Professor Bertram and Ph.D. student Nealan Gerrebos explain their latest research on how wildfire smoke may warm the Earth for longer than previously thought in The Conversation. Their research paper has been read more than 3,400 times within the past 10 days. You can find the original paper published in Proceedings of the National Academy of Sciences of the United States of America.

Global distribution of the phase state and mixing times within secondary organic aerosol particles in the troposphere based on room-temperature viscosity measurements (November 30, 2021) has been selected for a Virtual Issue entitled Atmospheric Aerosol Research jointly published by The Journal of Physical Chemistry A and ACS Earth and Space Chemistry.

Scientists discover three liquid phases in aerosol particles (April 12, 2021): Researchers in the Bertram Research Group, in collaboration with researchers at McGill University and the University of California, Irvine, have discovered three liquid phases in individual aerosol particles, changing our understanding of air pollutants in the Earth’s atmosphere (From ScienceDaily). The original paper was published in Proceedings of the National Academy of Sciences of the United States of America.

Probing Aerosols One By One (March 31, 2014): Methods reveal the chemistry of individual sea spray and mineral dust aerosol particles (From Chemical & Engineering News). This article featured our research on how changes in relative humidity can lead to phase transitions within individual aerosol particles.

Tiny airborne pollutants lead a double life (July 30, 2012): Researchers have provided visual evidence that atmospheric particles separate into distinct chemical compositions during their life cycle. Observations could have important implications for modeling global climate change and predicting air quality conditions (From ScienceDaily). The original paper was published in Proceedings of the National Academy of Sciences of the United States of America.
