Aerosol physicochemical properties and phase transitions - including their pH, phase, viscosity, surface tension, and hygroscopicity - are critical to understanding particle dynamics and chemical transformations. Submissions are welcome in the novel areas of aerosol science and technology in which phase is a controlling factor in microphysics and reactivity. The scope of this symposium includes aerosol studies of:
This symposium seeks to stimulate interdisciplinary discussion around, and highlight recent advances in, fundamental aerosol physical chemistry and microphysical phenomena that are essential to addressing a range of questions and applications. Studies bridging scales and using computational, experimental, and observational techniques are encouraged.

Indoor and outdoor air contain many thousands of aerosol constituents. Traditionally, ambient aerosol has been classified into broad components such as sulfate, nitrate, ammonium, organic carbon, elemental carbon, and other inorganic constituents. However, within these categories are extremely diverse chemical compounds including per- and polyfluoroalkyl substances (PFAS), highly-functionalized transformation products, biological components such as those from harmful algal blooms (HABs), microplastics, and secondary organic aerosol (SOA) from volatile chemical products (VCPs) or other understudied precursors. For many of these novel or less-studied constituents, their airborne concentrations, dynamics, chemical/physical properties, and health impacts are not well understood, and may necessitate the use of advanced experimental techniques and computational methods. This special symposia invites presentations spanning laboratory, field, and modeling work that focuses on aerosol sources of increasing importance and novel constituents of emerging concern across indoor, urban, regional, or global scales.

Biomass burning and incomplete combustion are an important source of organic aerosol particles, soot, semi-volatile organic compounds, and oxidants. In many cases, these combustion products can be transported indoors impacting the air quality of indoor environments. Recent advances in instrumentation have allowed for identification and investigation of these compounds and the aging of their products. Many of the chemicals associated with the emissions are carcinogenic or have other negative health implications. Additionally, the overall impacts can change (increase or decrease) as the smoke ages in the atmosphere or after it is transported indoors. In addition to wildland fires, indoor combustion of fuels for heating or cooking can also impact indoor air quality significantly. This session will provide an opportunity for presentations and discussions that target the role wildfires and indoor combustion play on the air we breathe.
The goal for this special symposium is to bring together researchers with cross-cutting interests focusing on all forms of biomass and fuel combustion and impacts on human health.
Submission topics considered for this special symposium can range from characterization of combustion/wildfire aerosol particles, chemical transformations, transport and deposition of particles, impacts on air quality (outdoor and indoor), human health, and mitigation/air cleaning strategies.

The COVID-19 pandemic has instigated considerable research and public discussion about the role of aerosols in infectious respiratory disease transmission. The AAAR community has been at the forefront of this process, leading scientific studies of how SARS-CoV-2 and other respiratory pathogens, such as influenza and tuberculosis, are transmitted and can be mitigated to protect public health. As the pandemic continues, this special symposium provides an opportunity to share and discuss what we now know, and don’t yet know, about infectious respiratory disease transmission and prevention. Topics focusing on any aspects of multidisciplinary research or discussions regarding the science of aerosols relating to infectious diseases will be considered. In particular, abstracts covering the following topics are encouraged:
It is anticipated that additional components of the special symposium will be organized outside the hours of the technical session (evening or immediately post-conference) to allow more time for discussion related to the intersections between these complex topics, including lessons that have recently been learned and areas that still require focused discussion and work.
(Through July 31)
Registration via the website portal will close on Sunday Sept. 25th, but you will still have the chance to Register in-person at the AAAR Registration Desk in the Raleigh Convention Center starting on Sunday October 2nd.
