  • The complex equilibria of sulfur compounds at the liquid-vapor interface play key roles in atmospheric processes. Here, using X-ray photoelectron spectroscopy, Raman spectroscopy, and molecular dynamics simulations the authors determining pKa values and tautomer ratios at the air-vapor interface in a liquid microjet.

  • Aerosol droplets have significant effects on atmospheric photochemistry, however measuring absorption from single droplets is a challenge. Here, the authors report a method to measure absorption of nanodroplets with attolitre sensitivity, showing rate enhancements for light focusing in photolysis reactions.

  • The applicability of high-resolution mass measurements of optically trapped particles is currently limited by experimental constraints, with no access the lower picogram range. Here, the authors propose a broadly applicable optical balance to accurately weigh submicron aerosol droplets down to the picogram level.

  • Obtaining dynamic information on atmospheric aerosol particle size and morphology is typically challenging. Here, the authors introduce holographic imaging of unsupported aerosol particles in air that are spatially confined by optical traps, allowing contact free observation over multiple timescales.
