This $400,000 federal Project Grant award from the National Science Foundation's (NSF) Division of Chemistry, CFDA 47.049 - Mathematical and Physical Sciences program, supports research by Professor Alison Bain of Oregon State University to investigate the effects of complex organic mixtures on the surface tension of aerosol droplets and their role in cloud droplet activation. The key objectives are to: 1) determine how different ratios of strong, moderate, and weak surface-active molecules...
This Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) provides $100,000 over 2 years to investigate the oxidation chemistry of organic aerosols in the atmosphere and its impact on their optical properties. The research will utilize innovative triple oxygen isotope measurements to elucidate the specific oxidation pathways that contribute to changes in aerosol composition, with the goal of understanding how these compositional changes affect...
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...
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...
This Project Grant from the National Science Foundation Division of Atmospheric and Geospace Sciences provides $217,400 to The Regents of the University of Colorado for collaborative research titled "Photochemical Silicon Aerosols: Establishing Atmospheric Sources and Significance."
