Hygroscopicity of Sub-6 nm Sodium Chloride Particles

摘要

We measured the hygroscopic growth of Sodium Chloride particles in a size range from 2.5 nm to 6 nm in a relative humidities ranging from 10% to 95% with a nano hygroscopicity tandem differential mobility analyzer The aim of this study was to investigate how accurately the K?hler theory describes the hygroscopic growth of particles with a diameter of few nanometers.
