Abstract:
Bubbles have had a huge impact on sewage treatment, electrocatalysis, food processing, biomedicine and so on. The broad application fields and diverse manipulation methods make bubble manipulation valuable for research. Inspired by natural organisms, bionic-based material surfaces with different wettability have an important impact on the dynamic control of bubbles. Different dynamic states of bubbles, ranging from bubble collection to self-driven control, external stimulus control and bubble splitting are examined in this review. Notably, the self-driven method is characterized by low energy consumption and automatic control, while the external stimulus method offers rapid response and precise control. Potential application areas include electrochemistry, microrobotics and underwater bubble collection. The dynamic control of bubbles is elucidated, with the hope of inspiring future innovations in the manipulation of bubbles and other fluids.

Capillarity in Fluid
Surface tension is crucial to capillarity. It results from cohesive forces between liquid molecules at the liquid-air boundary, forming a skin that resists external forces. When the capillary tube...
Surface Tension, Capillary Action, and Viscosity
The various IMFs between identical molecules of a substance are examples of cohesive forces. The molecules within a liquid are surrounded by other molecules and are attracted equally in all directions by the cohesive forces within the liquid. However, the molecules on the surface of a liquid are attracted only by about one-half as many molecules. Because of the unbalanced molecular attractions on the surface molecules, liquids contract to form a shape that minimizes the number...
