Dynamics of Liquid–Liquid Phase Separation in Submicrometer Aerosol

Nanoscale materials, when compared to their bulk components, possess unique properties. In particular, shifts in phase transitions can occur for submicrometer particles. For instance, small particles do not undergo the process of liquid–liquid separation (LLPS). LLPS has applications emulsions such as Janus particles, controllable morphology create drug-rich phases during drug delivery, and is often observed atmospheric aqueous aerosol tracked a function particle water activity, which equivalent relative humidity (RH) at equilibrium. We probed three organic/inorganic systems range RH over occurs (SRH). Our findings indicate that SRH lower than micrometer-sized droplets. These show it may be necessary update representation climate models. The vast majority have diameters, decrease indicates current estimation phase-separated aerosols overestimated. Furthermore, understanding properties nanoscale provide key parameters describe these lead better control
