Spontaneous and directional water transportation (SDWT) is considered as an ideal method has a great prospect in the aerospace ship fields. Nonetheless, existing SDWT limitation of slow velocity because its geometry structure configuration, which hinders practical application SDWT. To overcome this limitation, we developed new superhydrophilic serial cycloid-shaped pattern (SSCP) was inspired by micro-cavity shape Nepenthes. First, experimentally found that on SSCP faster than wedge-shaped (SSWP) analyzed mechanism. Then, influence parameters investigated single-factor experiment. In addition, enhanced to 289 mm s-1 combining experiment, orthogonal optimization design, streamline junction transition optimization, pre-wet pattern, fastest Moreover, demonstrated superior capability long-distance transportation, gravity resistant heat transfer, fog collection. This finding shows remarkable prospects high-performance fluid system.

Structured surfaces leverage interfacial energy for directional liquid manipulation without external power, showing tremendous potential in microfluidics, green and biomedical applications. While the interplay of between solid liquids is crucial manipulation, a systematic understanding how balance liquid–solid affects behaviors remains lacking. Here, using curvature-ratchet surface as generic example, we reveal complex dynamics inherent subtle regulation energy. We show that curvature tilt features regulate Laplace pressure asymmetry to enable directional, bidirectional reverse manipulation. These processes can be modulated by free tension, define their ratio new dimensionless number ζ characterize relationship. The balanced control happens when ∼ 1, which facilitates versatile behaviors, e.g., fan-shaped spreading, gradient-induced redirection, back-and-forth transport on various array arrangements, all resulting from matching structural designs with proper ζ. Inspired this, showcase an innovative liquid-based information encryption technique, where displays correct preprogrammed only at designated values. This study lays groundwork smart broadens its application domains.
