Ultrafast crystallization hollow nanocrystals of the resorcinarene hexamer in microfluidic via standing surface acoustic waves (SSAWs)

Abstract We demonstrate for the first time that standing surface acoustic waves (SSAWs)-based technique is a useful tool to fabricate hollow nano crystals in a microfluidics device. Hollow crystals with diameter from 200 nm to 30 μm are obtained in microdroplets by changing the input power and the time of sonication.
