Summary: Researchers have investigated the microscopic wetting phenomena of water on nonwetting nanoporous surfaces, characterizing the nanoscopic morphology and effective stiffness of liquid-air interfaces inside nanopores. They found that the nanomenisci exhibit apparent elastic deformation and size-dependent effective stiffness, and correlated these properties with the wetting behavior of water droplets on structured surfaces.

Summary: This study investigates the electrowetting-induced detachment of droplets from solid surfaces through simulation and experiments. The results show that optimal detachment can be achieved when the application of voltage is synchronized with the spreading time of the droplet. The droplet's ability to detach depends mainly on its contact angle, viscosity, and applied voltage.

Summary: The research investigates the coupling between liquid-liquid phase separation and the spreading motion of three-phase contact lines, finding that the classical Cox-Voinov law is no longer applicable and observing spreading beginning well before any visible nucleation of microdroplets. The study suggests that evaporation-induced enrichment, together with surface forces, causes an earlier nucleation in the wetting precursor film, initiating the observed wetting transition.

Summary: Liquid manipulation is important, and electrowetting on dielectric (EWOD) is a commonly used method. However, EWOD requires complex circuit control. Here, we develop an unexplored triboelectric wetting (TEW) phenomenon that directly uses triboelectric charges for precise water droplet control, eliminating the need for circuit control.

Summary: In this study, the researchers used a customized instrument to investigate the lateral adhesion forces on femtosecond laser-structured surfaces. They found that the droplet motion was significantly influenced by the chemical and topographical surface features. The droplet mobility was classified into static, transfer, and kinetic regimes, which is crucial for designing surfaces with extreme wetting characteristics.

Summary: This study investigates the influence of surface roughness on the capillarity of liquid bridges and the wettability of droplets on solid surfaces. The experimental results show that as the roughness of the surface increases, the wetting angle of the droplets increases while the capillary forces of the liquid bridges decrease.

Summary: This paper presents a method to study the interaction between particles and sessile gas bubbles by utilizing the full information from atomic force microscopy force-distance curves. The method allows the determination of contact angle, the position of the three-phase contact line, and the bubble profile without assuming a constant contact angle or opening angle. The proposed method was demonstrated for hydrophobic SiO2 and Al2O3 colloidal probe particles interacting with sessile gas bubbles.

Summary: Molecular dynamic simulation was used to investigate the wetting and electro-wetting behavior of nanodroplets of ionic liquid on a silicon solid substrate, as well as the influence of solid wettability and temperature on the wetting phenomenon. The results indicate that the equilibrium contact angle decreases with increasing solid wettability and temperature. When the nanodroplet wets a lyophilic surface, the effect of temperature is more pronounced. The droplet exhibits asymmetric electro-wetting on the lyophobic surface under the applied electric field, and this asymmetry diminishes with increasing energy parameter. The redistribution of cationic and anionic particles on the first wetting layer is found to be the main factor influencing the wetting behaviors.

Summary: The study explores the wetting behavior of an elastic filament floating on a fluid surface by another immiscible droplet, finding that tensions in the system obey an elastic version of the Young-Laplace-Dupre relation. While a purely geometric theory provides a good description of mechanical equilibria, curvatures near the contact line are not captured, possibly due to 3D effects. When a highly bendable filament completely wraps a droplet, there is continuity of curvature at the droplet-filament interface, leading to seamless wrapping similar to a 3D droplet.

Summary: This study observes the self-propulsion of aqueous droplets on a chemically homogeneous superhydrophilic surface and provides a theoretical model to explain this phenomenon. The research has important implications for the development of self-powered droplet-based microfluidic devices, and further investigates the effects of droplet volume, surface roughness, relative humidity, and composition on droplet velocity.

Summary: Superhydrophobic coatings with unique properties such as self-cleaning and staying dry have recently emerged in industrial and consumer markets. The stochastic nature of coating components can affect the uniformity of water repellency, and traditional contact angle goniometry may not provide accurate quantification of wetting properties. The study demonstrates that highly sensitive force-based methods can offer advantages in quantifying microscale heterogeneity in superhydrophobic coatings.

Summary: This study investigates the splashing behavior of millimetric droplets on convex and concave surfaces, and finds that the tendency of droplets to splash is proportional to the reciprocal of the substrate's radius of curvature, with it being harder for droplets to splash on small spheres.

Summary: Hydrophobic surfaces modified by pathogens in agricultural production reduce the utilization of pesticides, and surfactants are commonly added to improve wetting and spreading properties. This study found that nonionic surfactants are more effective than cationic surfactants for improving the wetting and spreading of pesticide solutions on cucumber powdery mildew leaves.

Summary: This paper presents a new physical model for wetting of a liquid droplet on a solid substrate, taking into account the minimum mechanical energy achieved by the droplet in equilibrium. The model considers not only the tangential forces on the wetted surface, but also the forces acting perpendicular to it, including dispersed forces acting on the entire interface.
