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 species and processes that lead to nanoparticle formation and growth, which could improve understanding of the role of new particle formation on clouds and climate. The research will involve experiments generating low-volatility gas phase precursors and clusters, and measuring their physical and chemical properties as they grow. Two modeling frameworks will be employed to determine the chemical mechanisms responsible for growth. The project will also provide educational and outreach opportunities for undergraduate and graduate students, as well as the general public. No sub-awards are planned under this grant.
