Summary: This study investigates the formation of surface nanodroplets on nanostructure surfaces, demonstrating that nanostructure patterning can effectively regulate the shape, contact radius, and nucleate site of nanodroplets. Nanodroplets exhibit different wetting properties on different structures, and the physical geometry and chemical heterogeneity of the substrate affect the growth and spreading of nanodroplets.

Summary: The spreading behavior of microdroplets differs from larger droplets due to the influence of size and surface tension. Experiments showed that the initial spreading of smaller droplets is shorter with reduced oscillation damping compared to millimeter-scale droplets. The coupling between spreading velocity and dynamic contact angle may have applications in microscale heat transfer, advanced manufacturing, and aerosol transmission studies.

Summary: This study investigates the effects of liquid surface tension and solid structure on the wetting and non-wetting behavior of droplets on solid substrates. The results show that the wetting behavior and droplet asymmetry are influenced by the liquid composition and structure spacing. A wetting regime map for a wide range of surface tension fluids and solid fractions is proposed.

Summary: This paper introduces an innovative approach to fabricate smart surfaces with strong pH-responsiveness by combining femtosecond laser direct writing (LDW) processing technology with stimulus-responsive polymer grafting. The fabricated smart surfaces exhibit robust and rapid responsiveness to acidic and basic droplets, providing potential applications in microfluidic devices, intelligent sensors, and biomedicine.

Summary: In this study, we achieved superhydrophobicity on stainless steel surfaces by designing micrometric pillars using a femtosecond laser. We investigated the wetting behavior evolution as a function of time and chemical environment, and found that the steady-state contact angles remained above 130 degrees 250 days after laser texturing. Comparing the results with undisturbed surfaces, we observed significant changes in droplet behavior when wetting measurements were conducted on unstable surfaces.

Summary: Based on the Wenzel model and Cassie model, this paper established a new wetting model for irregular rough surfaces and calculated the wetting depth and apparent contact angle. The experimental results showed significant differences in the surface texture parameters of different aggregates. The relative error between the predicted and measured contact angles was less than 15%, indicating excellent prediction effect. The wetting model analysis revealed that the surface tension of the test liquid, lithology of the solid aggregate, surface roughness, and texture structure are important control parameters affecting wetting.

Summary: This study investigates the wetting state and stability of an air layer trapped in micro-structures, plastron, under intense acoustic waves. The results show that the plastron behaves like a water-air interface at low acoustic intensity, and a wetting transition can be triggered by a sufficiently large acoustic radiation pressure at moderate intensity. Cavitation clouds appear under strong excitation, their sizes and positions depending on the surface acoustic boundary condition.

Summary: The study systematically investigated the effect of thermal treatments on mechanical properties in Ni/Mo multilayers. A supermodulus effect and large tensile stress development were observed in the annealed multilayers, along with the evolution of grain-boundary wetting. The results highlight the crucial role of interfacial structures in governing the elastic behavior of metallic multilayers.

Summary: The study prepared carbon microspheres using hydrothermal process, and investigated the compression behavior of wetted carbon-based disks made from carbon microspheres and polytetrafluoroethylene. It was found that the compressive stress exhibited statistical variability and followed a power-law relation with the average maximum strain.

Summary: Methods for fabricating super-liquid-repellent surfaces have traditionally relied on perfluoroalkyl substances, but concerns over their environmental and health effects have sparked interest in fluorine-free alternatives. Polydimethylsiloxane (PDMS) is a promising candidate, although it only exhibits superhydrophobicity instead of liquid repellency. In this study, we demonstrate that a well-designed two-tier structure of silicon dioxide nanoparticles and surface-tethered PDMS chains can achieve super-liquid-repellency towards low surface tension liquids. Our work highlights the feasibility of scalable fabrication methods and environmentally friendly surface functionalization for fluorine-free super-liquid-repellent surfaces.

Summary: This study investigates the anisotropic wetting on textured surfaces. Three stripe-like textures with different heights were created using three different polymers. The contact angle in all directions was measured using a lab-built goniometer. Two different behaviors, correlated to the wetting state, were observed. The Wenzel state showed strong anisotropy, with the contact angle following a Gaussian evolution. The Cassie-Baxter state, on the other hand, exhibited no anisotropy, with the contact angle remaining constant and close to the predicted value. This study deepens our understanding of droplet anisotropy by linking it to surface textures and chemistry.
