Abstract
Cluster formation in supersaturated aqueous solutions was investigated . In this study, single microparticles of aqueous sodium chloride and glycine solutions were suspended electrodynamically without a containe r in a spherical void electrodynamic levitator trap (SVELT) in a water vapor reservoir environment. Measurements of water activities were ma de far into the metastable zone. The dependence of the critical cluste r size on concentration in the metastable region was investigated empl oying nucleation theory. In addition, the number average cluster size was estimated from a relationship between the diffusion coefficient an d cluster size.
