This Project Grant award, funded by the National Science Foundation's (NSF) Mathematical and Physical Sciences Program (CFDA 47.049), supports a research project led by Professor James Smith of the University of California, Irvine. The $450,000 award, effective June 1, 2025 through May 31, 2028, will investigate the growth mechanisms of atmospheric aerosol nanoparticles, focusing on the interactions between organic compounds, inorganic acids, and bases. The project aims to identify the major...
The National Science Foundation (NSF) awarded a $797,203 Project Grant under its Geosciences program (CFDA 47.050) to the University of California Irvine (UC Irvine). The goal of this 3-year project, with an end date of January 2027, is to better understand how photochemical reactions in the solid or liquid phase of organic compounds affect the key properties of organic aerosol in the atmosphere. The research will focus on secondary organic aerosol (SOA) and/or biomass burning organic aerosol...
This three-year $570,934 National Science Foundation project grant supports research at the University of California, Irvine to study the effects of phase state on secondary organic aerosol partitioning and its impacts on atmospheric processes at regional and global scales. Specifically, the university will implement methods in the GEOS-Chem model to predict glass transition temperatures and viscosity of secondary organic aerosol. Researchers will derive equilibration timescales of...
This Project Grant award from the National Science Foundation (NSF) Division of Chemistry, under the Mathematical and Physical Sciences (CFDA 47.049) Federal Grant Program, provides $184,839 to Christopher Newport University (CNU) and California State University Monterey Bay (CSUMB) to conduct collaborative research on the interactions of ions at interfaces. The research aims to elucidate the properties that govern the distribution and identities of ions in atmospheric aerosols, which is crucial...
This National Science Foundation (NSF) Project Grant award under the Geosciences program (CFDA 47.050) will fund a collaborative research project to quantitatively assess the influence of salt on the aqueous partitioning of water-soluble organic gases in the atmosphere. The $709,720 award, effective December 15, 2024 through November 30, 2027, will support field and laboratory measurements, reanalysis of prior atmospheric chemistry data, and the development of parameterizations for...
This federal Project Grant award of $750,000 from the National Science Foundation's (NSF) Mathematical and Physical Sciences (CFDA 47.049) program will fund experimental and computational studies of the aqueous chemistry of organic peroxy (RO2) radicals. The research team, led by Professors Jesse Kroll and William Green from the Massachusetts Institute of Technology (MIT), will investigate the chemical reactions these highly reactive radicals undergo within cloud droplets and fine particles in...
This $419,614 Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) supports collaborative research led by the University of Maryland Baltimore County (UMBC) to quantitatively assess the influence of salt on the aqueous partitioning of water-soluble organic gases in the atmosphere. The research objectives include: 1) measuring the effects of atmospherically relevant inorganic salt mixtures on partitioning of ambient water-soluble organic gases; 2)...
This three-year project grant from the National Science Foundation Division of Atmospheric and Geospace Sciences provides $195,299 to the University of North Carolina at Chapel Hill for research characterizing the cloud formation properties of secondary organic aerosol formed from aqueous multiphase chemical processes. The research will be conducted from October 2021 through September 2024 under the Geosciences program (CFDA 47.050), which supports basic research into the integrated Earth system...
This Project Grant award of $499,590 from the National Science Foundation's (NSF) Mathematical and Physical Sciences program (CFDA 47.049) supports a computational study by Professor George Shields and 12 undergraduate students at Furman University to better understand the energetics of molecular clusters in the atmosphere that can form atmospheric aerosols and influence cloud formation. The research aims to optimize processes for calculating Gibbs free energy changes for the formation of...
The National Science Foundation (NSF) awarded a $599,648 Project Grant under the Mathematical and Physical Sciences (CFDA 47.049) program to the University of California, San Diego (UCSD) to investigate the chemistry of biological macromolecules, such as proteins and environmental DNA, in aqueous aerosols. The 2-year project, led by Professors Vicki Grassian and Rommie Amaro, will integrate laboratory experiments and computational simulations to study the behavior of these macromolecules at...
