Our paper led by Swarup China and Susannah Burrows (both from PNNL) is published in Nature CommunicationsContrary to common assumption that sodium-containing atmospheric particles originate primarily from marine sources, our research shows that particles with very similar 'sea spray-like' composition and sizes are also abundantly emitted by tropical forests.

An ACS eBook "Multiphase Environmental Chemistry in the Atmosphere" edited by Sherri W. HuntAlexander LaskinSergey A. Nizkorodov is published. The book content is based on presentations given at the symposium with the same title held at the 2017 ACS Fall meeting. This book highlights new cross-disciplinary advances in aerosol chemistry critical for more accurate modeling of the atmospheric environment.


We are a multi-disciplinary experimental group with research interests in the areas of Analytical and Physical Chemistry of airborne particles and environmental interfaces, driven by the overarching goals of understanding their impact on the atmospheric chemistry, the air pollution and the Earth’s climate. Our research efforts include three inter-related areas: Development and applications of new analytical methods for chemical characterization of aerosols; Chemical imaging and molecular-level studies of field collected particles; Laboratory studies of multi-phase chemistry of particles and interfaces.
