Outline of Final Research Achievements

Organic aerosol, which is tiny particles with several hundred nanometers, has chemical and physical reactions on its surface and inside and influences the global climate. This study aims to investigate these properties using electron microscopy. The technique developed in this study reveals viscosity, volatility, and compositions of organic aerosols collected from various environments. Especially, I found that some organic aerosols are solid and have less volatility than that in previous estimation.
