Measurement of the Surface Energy of Unsupported Nanocrystals

Abstract

A novel method to study the evaporation kinetics of nanocrystals (NC) is developed. Direct in situ measurement of mass change using a tandem ion-mobility size and mass spectrometers is used to determine the size dependent evaporation rate. A kinetic model is used to relate the evaporation rate to the temperature dependent surface energy. We report… (More)
