Aerosol equilibrium thermodynamics and hygroscopicity

The focus of this project is on understanding the thermodynamics and hygroscopic properties of water-soluble and insoluble organic components found in atmospheric aerosol. Hygroscopic properties regulate particle phase and size and, thus, influence the impact of aerosols and clouds on climate. Further, we are studying the phase segregation of hydrophilic and hydrophobic phases in aerosol , focussing particularly on the formation of immiscible liquid phases and the change in mixing state with environmental conditions and gas composition.
