AAAR 38th Annual Conference

The 38th American Association for Aerosol Research (AAAR) on October 5th-9th is being held virtually for the first time in its history. Like the previous years, researchers form IndoorChem community will be presenting results from the Chemistry of Indoor Environments program funded projects. The conference program can be accessed here. We have compiled a list of the relevant talks, both platform and poster, as outlined below:


All times are in Eastern Daylight Time (EDT).
