Fig.5 Schematics of the formation of rubidium sol (a) ultrasonic cavitation effect (b) schematic of the formation of rubidium NPs in toluene (I: cavitation bubble collapse induced mutual sputtering of rubidium and toluene at their interface, which produces relatively large liquid rubidium particles; II: smaller rubidium droplets produced via repeated cavitation bubble collapse; III: rubidium droplets reach critical size to form sol)
