由于重力引起的排水和液体蒸发，空气中的气泡是短暂的，这严重限制了它们的应用，特别是作为有趣的生物/化学反应装置。本文提出了一种利用声悬浮和受控液体补偿相结合的方法来稳定气泡的新方法。由于声场的抑制作用和液体补偿对毛细管波的阻挡作用，气泡可以永久保持稳定和完整。研究发现，由于气泡的振荡和内部声流的存在，声悬浮气泡对颗粒的吸附能力显著增强。这一结果为无需消耗任何固体过滤器的新型空气净化技术的发展提供了启示。这项工作报告了一种稳定气泡的新方法，通过使用声悬浮和受控液体补偿相结合，气泡可以永久保持完好。声悬浮气泡对颗粒的吸附能力显着增强，这为发展新型空气净化技术提供了新的思路，而无需任何固体过滤器。
Bubbles in air are ephemeral because of gravity‐induced drainage and liquid evaporation, which severely limits their applications, especially as intriguing bio/chemical reactors. In this work, a new approach using acoustic levitation combined with controlled liquid compensation to stabilize bubbles is proposed. Due to the suppression of drainage by sound field and prevention of capillary waves by liquid compensation, the bubbles can remain stable and intact permanently. It has been found that the acoustically levitated bubble shows a significantly enhanced particle adsorption ability because of the oscillation of the bubble and the presence of internal acoustic streaming. The results shed light on the development of novel air‐purification techniques without consuming any solid filters. This work reports a new approach to stabilize bubbles that by using acoustic levitation combined with controlled liquid compensation the bubbles can remain intact permanently. The acoustically levitated bubble shows a significantly enhanced particle adsorption ability which shed light on the developing of novel air‐purification techniques without consuming of any solid filters.
