Summary: This study reveals that the receding contact angles of droplets decrease with the decrease in the pillar spring constant. Surprisingly, densely packed pillar arrays may result in larger receding contact angles than sparsely packed pillars, which is contrary to the understanding of rigid pillar arrays.

Summary: Surface wetting significantly influences material performance and applications, with superhydrophobic surfaces exhibiting water repellency due to their low surface energy chemistry and micro/nanostructure roughness. The next generation of superhydrophobic surfaces, Multifunctional SHSs, are rapidly evolving with properties including self-healing, anti-bacterial, anti-fouling, and stimuli responsiveness. Designing durable Multifunctional SHSs with self-healing functions can enhance performance and lifespan, with a focus on parameters such as durability, stability, more functions, responsiveness, and environmentally friendly features.

Summary: In recent years, there has been extensive research on synthetic superhydrophobic surfaces, which possess unique anti-wetting properties. Apart from their stay-dry and self-cleaning properties, the evaporation process of water droplets has also attracted significant interest. Studies on surface contamination and droplet evaporation during the Covid-19 pandemic have gained attention. Superhydrophobic surfaces alter the contact between droplets and the substrate/environment, and affect the diffusion of vapor.

Summary: Supercooled droplet freezing on surfaces is a common phenomenon in nature and industry, but little is known about its effect on droplet-substrate interactions and the design of icephobic surfaces. This study investigates freezing of supercooled droplets on textured surfaces and identifies surface properties that promote ice expulsion. The study also explores mechanisms through which repellency falters and provides insights into the phenomenology of ice adhesion throughout freezing. The findings contribute to the design of icephobic surfaces for increased safety and sustainability in engineering applications.

Summary: The bouncing dynamics of water nanodroplets on superhydrophobic Pt surfaces with nanopillar arrays is comprehensively studied using molecular dynamics simulations. It is found that there are critical values of the solid fraction and pillar height to induce pancake bouncing at the moderate Weber number. A theoretical model is developed to quantitatively proclaim the dependence of nanostructure features and the critical Weber number on pancake bouncing.

Summary: Applying an electric field across superhydrophobic surfaces with miniature corrugations can induce transitions between the Cassie and Wenzel states, allowing for reversible cycling between the two states. The response times to changes in the electric field are of nano-second scale, enabling fast cycling frequencies up to GHz.

Summary: The study demonstrates that slow movement of Pseudomonas aeruginosa is vital for its collective migration across surfaces, as it avoids being trapped by topological defects resulting from faster cell movements. In contrast, faster mutant cells are overtaken and outcompeted by slower wild-type cells at high cell densities, leading to faster collective behavior and migration. The physics of liquid crystals helps explain how bacteria can outcompete each other in the race for new territory by generating topological defects that trap fast-moving cells.

Summary: It has been revealed that weakening intercellular contacts is a fundamental process essential for the switch from extensile to contractile tissue behavior. This switch leads to the accumulation of tension at the cell-substrate interface through an increase in actin stress fibers and traction forces. Mechanotransductive changes in vinculin and YAP activation accompany this transition.

Summary: This study numerically investigates the morphology and disclination line dynamics of active nematic droplets in three dimensions, revealing a wide range of complex behaviors. The interaction between active anchoring, active flows, and the dynamics of the motile disclination lines are found to explain the diversity of behavior observed. The findings suggest that some biological systems may share the same underlying mechanisms as active nematic droplets, providing insights into processes such as morphogenesis and collective cancer invasion.

Summary: This study explores the spontaneous flow generation by activity pulses using an active gel model, and demonstrates that the cross-talk between activity-induced deformations and the viscoelastic surroundings can lead to a reversal of active flows. The study emphasizes the importance of relaxation time scales of polymers and active particles in witnessing such spontaneous flow reversals in complex microenvironments, suggesting new experiments to investigate the role of controlled pulses of activity in living systems.
