Summary: In this study, flexible structures resembling micro-nano pillars, setae, and cilia found on natural organism surfaces were created using a novel fabricating strategy to investigate the phenomenon and mechanism of droplet formation. By adjusting the mold pattern, different micro/nano morphologies could be easily obtained on a smooth film surface. The film, with its uniformly distributed hierarchical micro-nano structure arrays, demonstrated superhydrophobicity, low-adhesion, self-cleaning, anti-icing, and deicing characteristics, making it suitable for various engineering applications.

Summary: This review summarizes the developments in preparing wrinkled structures with variable characteristics. It discusses the formation of smart interfaces with reversible wrinkle formation, the construction of wrinkles in non-planar supports, and the development of complex hierarchically structured wrinkled patterns. Smart wrinkled surfaces obtained using light-responsive, pH-responsive, temperature-responsive, and electromagnetic-responsive polymers are thoroughly described. This review also presents examples of the potential of wrinkle formation to create more complex patterns and the modulation of wrinkle characteristics for specific applications.

Summary: In this study, highly stretchable sensors with hierarchical wrinkled structures were fabricated using a two-step process of water-induced swelling and silver nanowire deposition. These sensors show promising applications in fields such as human motion detection and personal healthcare monitoring. The sensors exhibit high sensitivity, good electrical repeatability, and reliable responses to stretching/releasing. The 3D printed sensors have been used for human motion detection, demonstrating their potential in wearable electronics for healthcare monitoring and rehabilitation.

Summary: Superhydrophobic nanofibrous membranes were prepared by combining humidity-induced electrospinning and thermal-pressing treatment. The hierarchical rough structures generated from humidity-induced phase separation endowed the fiber with superhydrophobicity, and the thermal-pressing manipulation ensured strong physical bonding between nanofibers, greatly improving the membrane's mechanical and waterproof performances. The resulted membranes exhibited desirable superhydrophobicity, with a water contact angle of 151 degrees, remarkable water and oil intrusion pressures of 81.8 and 36.2 kPa, a high water vapor transmission rate of 7948 g m- 2 d-1, and satisfactory tensile strength of 8.1 MPa.

Summary: Understanding the functions and origins of proteins requires dissecting them into independent fragments, with structural domains being the typical level of analysis. SWORD2 is a web server that helps to explore protein structures by decomposing them into hierarchical protein units. It provides relevant substructures and can be useful for both biologists and bioinformaticians studying proteins.

Summary: Superhydrophobic surfaces have extreme water-repellence and can improve liquid mobility and reduce thermal resistance for heat-exchanger applications. This study investigates coating-free aluminum micro/nanopatterns fabricated using micromilling or laser-etching techniques and their wetting properties. It is found that line-edge-roughness plays a more important role in the resultant wetting properties than the structure geometry.
