The origins of the size dependent morphology organic aerosol are explored by probing poly(ethylene glycol)-400/ammonium sulfate mixtures using cryogenic-transmission electron microscopy. Surprisingly, we observe a dependence at some compositions, but not others. Our results suggest that occurs due to an activated process.
