Short summary
This study examines how organic films on soot particles influence how alcohol vapors are taken up and released. Laboratory measurements and computer simulations show that very thin organic coatings unexpectedly trap alcohols by forming stable surface layers, while thicker coatings favor faster release. The results reveal that particle surface structure strongly controls pollutant aging in the atmosphere, with important implications for air quality, cloud formation, and climate.
