Summary: A Janus wood (JW) with a continuous wettability gradient was created through unidirectional vacuum impregnation of a hydrophobic solvent. The presence of wettability gradient effectively reduced liquid penetration, increased flow rate and transport efficiency. The JW membrane prepared by this method exhibited excellent mechanical properties, stability, durability, and environmental friendliness.

Summary: The traditional methods for preparing Janus membranes are either too complex or lack precise control over surface wettability, layer thickness, and pore structure. This study successfully regulated asymmetric wettability and layer thickness on copper mesh using an interface-confined surface engineering strategy, enabling efficient liquid manipulation. The Janus copper mesh demonstrated superior performance in oil/water separation and fog collection, showing potential for applications in various fields.

Summary: This study investigates how microridges on cactus spines affect the movement of droplets on conical fibers. Microridges were found to reduce the base radius and contact area of droplets, increasing driving force and reducing friction force. Introducing a triple concave cross section to mimic microridges resulted in higher droplet velocity and distance traveled compared to traditional circular fibers.

Summary: In this study, an optimization strategy based on wettability combination and fork-row arrangement is proposed to broaden the effective working range of fog collectors for different concentrations of fog. The results showed that a hydrophilic surface works better in light fog, while a hydrophobic surface has a higher collection rate in heavy fog. The combination of different wettability surfaces performed best in different fog concentrations. Changing the arrangement from smooth-row to fork-row significantly improved the collection rate. The layer spacing also influenced the fog collection performance.

Summary: This paper discusses the efforts of scientists to alleviate the scarcity of fresh water resources, as well as the elegant water-harvesting schemes developed by various biological species for survival. The key factor for reliable water collection materials is the design of robust hierarchical configuration. Future prospects include mechanisms, characterization, design strategies, and fabrication techniques in the development of bionic directional water collection materials.

Summary: Fog water collection can serve as an alternative source of water supply in areas with limited water resources, but the amount collected is affected by season and meteorological conditions. The orientation of collectors and the frequency of foggy days in the area are among the main factors influencing the differences in yield between collectors.

Summary: This study investigates the hydrodynamic performance of double manta rays in group gliding, focusing on the effect of arrangement and attack angle. The results show that double manta rays in tandem and parallel arrangements experience systematic drag reduction, while no systematic drag reduction is observed in vertical cluster gliding. The average lift received by the group system is similar to that of a single body, regardless of the arrangement, and the difference in lift among individuals decreases with increasing arrangement spacing.

Summary: The development of technologies such as big data analytics, cloud services, IoT, personal mobile devices, social networks, and AI has created a strong demand for enterprises to accumulate information. The amount of recorded data is increasing by about 30-40% per year. Magnetic tape, hard disk drives, and solid-state drives are used for data storage. Hard disk drives are projected to control over half of the world's data due to their low cost per TB. This paper discusses new technologies to meet the growing density demands and competitive solid-state drives for data storage.
