PhD thesis: The influence of physical state on hygroscopicity and vapor pressure of single, levitated aerosol particles containing organics

Research interest

• Hygroscopicity, deliquescence and efflorescence, of mixed aqueous surfactant/salt aerosol particles in the presence of micelle forming.
• The vapor pressure of some lower chain length dicarboxylic acids for both, liquid aqueous aerosol particles and solid, crystalline particles.
• The water uptake impedance for particles in a glassy state.

The laboratory experiments were performed with single aerosol particles in an electrodynamic balance (EDB).
