Role of anisotropic pinning and liquid properties during partial rebound of droplets on unidirectionally structured hydrophobic surfaces

Vartika Parihar et al.

Summary: The study focuses on droplet impact dynamics on super-hydrophobic surfaces and finds that partial rebound phenomena, such as the formation of satellite drops, can occur even on hydrophobic surfaces.

Dynamic spreading characteristics of droplet on the hydrophobic surface with microstructures

Jizu Lyu et al.

Summary: Experimental study on droplet impact on two different microstructures (regular micro-grooved structure and irregular microstructure) with hydrophobic features reveals that the regular micro-grooved structure accelerates droplet spreading more effectively compared to the irregular microstructure. It is observed that droplet tends to break up when bouncing on the irregular microstructure surface, while a beating phenomenon of droplet height during impact is developed on the regular micro-grooved structure surface.

Motion of adhering droplets induced by overlapping of gravitational and periodical acceleration

B. Barwari et al.

Summary: This experimental work investigates the motion behavior of adhering water droplets under the influence of gravity and harmonic surface vibration. Different motion patterns and regimes are observed based on various process parameters, such as droplet volume, plate inclination, frequency, and acceleration. The analysis shows that increasing acceleration leads to chaotic contour deformation of the droplet, while different frequencies may cause the droplet to either start moving or be decomposed into smaller droplets.

Dust mitigation by rolling water droplets from hydrophobic surfaces

Bekir Sami Yilbas et al.

Summary: This study examined the mechanism of cleaning environmental dust from hydrophobic surfaces using rolling water droplets, analyzing the elemental composition and shapes of dust particles, as well as the solubility of some dust compounds in water. Hydrophobic glass surfaces were treated with functionalized nano-size silica particles, and the process of droplet fluid infusion on dust particle surfaces was monitored. The findings showed that alkaline and alkaline earth metal compounds in dust can dissolve in water, potentially damaging dusty surfaces, while the covering of droplet liquid on dust particles is essential for their removal from hydrophobic surfaces by rolling water droplets.

Hierarchical hydrophobic surfaces with controlled dual transition between rose petal effect and lotus effect via structure tailoring or chemical modification

Chunnan Wang et al.

Summary: Divergences in superwettability between lotus leaves and rose petals stem from minute differences in their morphological features. The controllable fabrication of hierarchical surfaces with distinct wetting behaviors can be achieved by regulating the preparation conditions.
