Bubbling of Ferrofluid Droplets via Coupled Magnetic and Sound Fields (Adv. Mater. Interfaces 7/2023)

Ferrofluid Bubble Formation In article number 2201724 by Kangqi Liu, Yuan Gao, Duyang Zang, and colleagues, a ferrofluid drop was turned into a bubble in a controlled manner by coupling the effect of magnetic and sound fields. The acoustically levitated bubble can serve as an ideal template for evaporation-induced assembly.
