Influence of Nonpolar Amino Acids on Phase Transitions of Atmospheric Aerosol Particles

Abstract The fate of aerosol particles in the atmosphere depends, in part, on their composition, morphology, and phase transitions. Studies of aerosol phase transitions have focused on aerosol particles with organic compounds consisting of C, H, and O atoms, although a substantia...

Single-Particle Visualization of Water Uptake of Organic–Inorganic Aerosols with In Situ Transmission Electron Microscopy

Abstract Atmospheric aerosol water uptake properties influence cloud formation and precipitation, atmospheric chemistry, and global climate. Atmospheric aerosols often contain organic acids and inorganic hygroscopic salts, and their internal mixing influences water uptake propert...

Significance of Size‐Dependent Hygroscopicity Parameterization for Aerosol‐Cloud Interactions

Abstract Aerosol‐cloud interactions (aerosol indirect effects) are the most significant source of uncertainties in the effective radiative forcing (ERF) due to aerosols which can act as cloud condensation nuclei (CCN). Uncertainties in the indirect effect can result from systemat...
