摘　　要：Bubbles,often seen as metaphors for transience due to their ephemeral nature,have fascinated artists,engineers,and scientists for centuries.Despite centuries of research,new and often surprising bubble physics and applications continue to emerge.In particular,bubble-oriented fluid dynamics has been shown to play an important role in various disciplines such as chemistry,colloidal science,catalysis,electrolysis,medicine,biology,geophysics,and many others.1,2 There has been a strong motivation for researchers to investigate and manipulate the lifetime of bubbles,which could help address important questions related to chemical engineering,food/cosmetics industry,and even geophysics.For instance,the lifetime of bubbles is linked to the stabilization of foams and the size of bubblebursting aerosols.To this end,as the recent discovery of Xiaoliang Ji and coworkers reveals,bubbles suspended in ultrasound could show extraordinary stability without any chemical stabilizers.3 With the bubble lifetime effectively prolonged by approximately two orders of magnitude,their work proposes a new method to produce a longlived bubble.
