Summary: The phenomenon of droplet jumping induced by coalescence has potential applications in water collection, self-cleaning, and thermal management of electronic devices. A numerical simulation was conducted to examine the similarities and differences in droplet jumping on superhydrophobic surfaces with uniform and non-uniform micropillars, as well as the effect of micropillar nonuniformity. The results showed that non-uniform distribution of micropillars affected the shrinkage of the liquid bridge, droplet morphology, and high-pressure region distribution, resulting in changes in droplet jumping velocity.

Summary: Two different superhydrophobic surfaces, the sheet-like structure and the cluster-like structure, were fabricated on copper substrates to study their microstructure and droplet jumping behavior, resulting in the formulation of a droplet jumping phase map. The sheet-like structure surface, with lower solid/liquid contact area and interfacial adhesion, showed more favorable droplet jumping behavior. Experimental results demonstrated the superior anti-corrosion performance of the sheet-like structure surface due to droplet jumping-induced wetting transition, offering design guidelines for applications in atmospheric corrosion protection.

Summary: The study systematically investigates the effect of structural parameters of the triangular prism on droplet jumping velocity on superhydrophobic surfaces. Results show that exploiting structure effects can greatly increase droplet jumping velocity, with the optimal length of the triangular prism reaching a plateau. The ratio of translational kinetic energy to released surface energy during droplet jumping is determined by the apex angle and height of the triangular prism, being more effective with a smaller apex angle and a larger height.

Summary: Investigated the dynamics of droplet impact on inclined ridged superhydrophobic surfaces and found the influence of We(n) (the normal Weber number) and alpha (the inclination angle) on the contact time tau. As We(n) increases, tau first decreases rapidly and then reaches a platform. In the middle and high We(n) regions, the contact time is reduced by 30% and 50%, respectively. The analysis demonstrates that tau in the middle and high We(n) regions is independent of We(n) and alpha, while the range of middle and high We(n) regions is related to alpha.

Summary: This study experimentally explores the impact behavior of droplets on superhydrophobic surfaces with single pillars of different sizes. The effects of Weber number and the pillar-to-droplet diameter and height ratios on the contact state between the droplet and solid surface and the maximum width are investigated. The results show that increasing pillar size reduces the maximum width factor of impact droplets, and the critical Weber number for touching the substrate and forming liquid fingers is influenced by the pillar-to-droplet diameter and height ratios. A theoretical model based on energy conservation is developed to calculate the maximum width factor on the single-pillar superhydrophobic surfaces, which agrees well with experimental results within a +/- 10% prediction deviation.

Summary: Superhydrophobic surfaces with different shapes and sizes of ridges were investigated for their maximum axial spreading of impacting droplets. A mathematical formula was proposed to describe the shape of the structures using a shape factor for easy application in structure-related studies. The effects of ridge shape and size on the maximum axial spreading coefficient were clarified. The outward flow of liquid above the ridge tip hindered the axial spreading of droplets, and the maximum axial spreading coefficient decreased as the ridge became sharper, achieved by increasing the shape factor or the ridge height-width ratio. The complex effect of the ridge-droplet size ratio was divided into two regimes based on the shape factor. A prediction correlation for the maximum axial spreading coefficient was established, considering the coupled effects of all parameters, and shown to agree well with experimental and simulation results.

Summary: Despite the extensive research on Leidenfrost droplet motion in its boiling regime, little attention has been paid to the droplet motion across different boiling regimes where bubbles are generated at the solid-liquid interface. In this study, experiments are conducted to investigate the behavior of Leidenfrost droplets on substrates with varying wettabilities and temperature gradients. A novel phenomenon of droplet motion that resembles a jet engine is observed on a hydrophilic substrate, where the droplets repulse themselves backwards as they travel across boiling regimes.

Summary: This study investigates the relationship between the morphology of PMMA monopolymers and PMMA-PHEMA copolymers with the expected nature of surfactant-free microemulsions (SFMEs) before polymerization. It is found that previously mesostructured, surfactant-free mixtures can produce porous polymers of different morphologies, while unstructured, oil-rich regions lead to solid, transparent polymers without nanostructured morphologies. Additionally, a surfactant-based reference system shows similar phase behavior and polymer morphologies as the comparable surfactant-free system, indicating the importance of the hydrotropic behavior of HEMA in this system.
