We are very pleased to welcome Annesha Devi, who is joining the group this summer to research phase separation in organic aerosols
through a cross funded project with the WLIURA program.
(May 2021)


Yuanzhou Huang, et al., in collaboration with scientists at McGill University and the University of California, Irvine, have discovered the coexistence of three liquid phases in aerosol particles, changing our understanding of air pollutants in the Earth’s atmosphere. While aerosol particles were known to contain up to two liquid phases, the discovery of an additional liquid phase will assist in providing more accurate atmospheric models and climate predictions. The study was published in PNAS.

“Aerosol particles are ubiquitous in the atmosphere and play an important role in air quality and the climate system. These particles can contain mixtures of primary organic aerosol, secondary organic aerosol, and secondary inorganic aerosol. We show that such internally mixed particles can contain three liquid phases. We also demonstrate that the presence of three liquid phases impacts the time needed for the particles to reach equilibrium with the surrounding gas phase and likely impacts the ability of the particles to activate into cloud droplets. A framework is presented for predicting conditions needed for the formation of three liquid phases in the atmosphere. These results will lead to improved representations of aerosols in models for air quality and climate predictions.”
