Project Grant 2046164

This three-year, $749,453 National Science Foundation project grant funds research at the California Institute of Technology into the atmospheric oxidation of volatile chemical products and their impact on air quality. Led by Drs. Paul Wennberg, Brian Stoltz, and John Crounse, the research team will study the chemical reactions of oxygenated hydrocarbons as they degrade in the atmosphere. A major focus is whether radical autoxidation pathways produce highly oxygenated compounds that contribute...

The National Science Foundation Division of Chemical, Bioengineering, Environmental, and Transport Systems awarded a 3-year, $250,000 Project Grant to the University of Illinois Urbana-Champaign to characterize the sources and sinks of the oxidative potential (OP) of indoor fine particulate matter (PM2.5). The objectives are to 1) investigate the evolution and dynamics of the OP and reactivity of indoor PM2.5 from indoor and ambient sources, 2) establish an inventory of the OP of PM2.5 emitted...

This Project Grant award, in the amount of $274,143, was provided by the National Science Foundation (NSF) under the Mathematical and Physical Sciences program (CFDA 47.049). The award supports Professor Haofei Zhang at the University of California, Riverside in investigating the roles of gas-phase OH and HO2 radicals in the multiphase oxidation of organic aerosols (OA) under atmospherically relevant conditions. The research aims to provide critical knowledge for understanding aerosol aging...

This $1,882,550 National Science Foundation project grant supports research into the evolution of secondary organic aerosol (SOA) formation processes in urban atmospheres. Funded under the Geosciences program (CFDA 47.050), the three-year award to the University of Colorado will investigate the key gas-phase precursors and sources contributing to SOA, and evolution of associated chemistry over the past decade. A six-week field campaign in the Los Angeles area in summer 2022 aims to compare...

This three-year Project Grant from the National Science Foundation's Division of Chemistry, totaling $413,144, supports collaborative research between Columbia University and Utah State University on surface-specific aerosol chemistry. The researchers will apply unique laboratory methods—surface-specific sum frequency generation and highly-sensitive hyperRaman scattering—together with gas-particle chemical kinetics studies, to characterize processes unique to aerosol surfaces. They will...

This $454,308 CAREER Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) will support Carnegie Mellon University's research to assess the role of atmospheric new particle formation (NPF) in influencing pre-industrial climate. The project will develop a new parameterization of NPF that accounts for temperature and atmospheric ions, and evaluate its effectiveness through climate modeling. The research aims to improve understanding of aerosol-cloud...

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, awarded by the National Science Foundation (NSF) Division of Atmospheric and Geospace Sciences under the Geosciences program (CFDA 47.050), supports experimental and theoretical research to improve understanding of the dry deposition velocity of particles in the atmosphere. The $432,369.00 award to North Carolina State University will fund the following key activities over a 3-year period from August 1, 2023 to July 31, 2026: Conduct chamber measurements to assess the effects...

Dr. Emily Franklin was awarded a $300,000 National Science Foundation Mathematical and Physical Sciences Ascending Postdoctoral Research Fellowship (NSF MPS-ASCEND) project grant to conduct research from September 1, 2022 to August 31, 2025. The grant supports Dr. Franklin's research project titled "MPS ASCEND: Characterizing Contributions of Volatile Chemical Products to Aerosol Chemistry and Composition in the Modern Megacity." Under this award, Dr. Franklin will (1) establish...

This Project Grant award from the National Science Foundation's (NSF) Engineering program (CFDA 47.041) provides $420,000 in funding to the Regents of the University of Michigan to study the chemical reactions and fates of quaternary ammonium compounds (QACs) in indoor environments. The key objectives are to measure the oxidation kinetics and reaction products formed when QACs, commonly used as antimicrobial agents in cleaning products, undergo atmospheric aging processes indoors. This will...
