Summary: Eliminating benzene and formaldehyde pollution is crucial in today's society of colorful home decoration. This study demonstrates the possibility and advantages of using vividly colorful amorphous photonic crystals (APCs) as catalytic pigments. By introducing oxygen vacancies through thermal vacuum de-oxygenation, SiO2@TiO2-x APCs with angle-independent structural colors and enhanced photocatalytic performance were successfully synthesized. The presence of oxygen vacancies in TiO2-x promotes electron activation and synergistically improves the degradation of formaldehyde, effectively protecting the beautiful living environment of human beings.

Summary: This paper investigates the challenge of achieving unidirectional and long-distance oil transport in an aqueous environment and successfully fabricates an underwater superoleophilic two-dimensional surface (USTS) with asymmetric oleophobic barriers to arbitrarily manipulate oil in water. The behavior of oil on USTS is found to have unidirectional spreading capability originated from the anisotropic spreading resistance resulted from the asymmetric oleophobic barriers. Additionally, an underwater oil/water separation device has been developed to achieve continuous and efficient oil/water separation and prevent secondary pollution caused by oil volatilization.

Summary: Directional liquid transport is crucial for practical applications, and various methods have been explored. However, achieving real-time transformation of liquid transport direction on material surfaces remains challenging. In this study, we demonstrate a curvature responsive anisotropic wetting strategy based on V-shaped prism microarray (VPM) microstructure on an elastic film. The arrangement of V-shaped prisms on the elastic film changes with the curvature, leading to a change in liquid wetting trend and even reversal of the liquid moving direction. Additionally, the surface hydrophobicity of the VPM elastic film also affects the liquid wetting trend and can result in the opposite transport direction of the liquid.

Summary: Inspired by glass sponges, researchers have developed a robust superhydrophobic three-dimensional porous skeleton that effectively inhibits hydrate nucleation while maintaining superhydrophobicity. The skeleton's high specific area allows for increased content of inhibitory groups without compromising its superhydrophobic properties, achieving inhibition of fresh hydrates and preventing adhesion to formed hydrates. Molecular dynamics simulations and experimental data demonstrate the effectiveness of the skeleton in prolonging hydrate formation induction time and reducing hydrate adhesive force. This research opens up new possibilities for novel materials in various industries, including oil and gas, carbon capture and storage.

Summary: Robust and reversible wet attachments are crucial for medical engineering and wearable electronics. The discovery of unique hierarchical micro-nano fibrous pillars on Chinese bush crickets shows a wet friction that is approximately 3.8 times higher than that of tree frog's bulk pillar. By introducing a nano-fibrous pillar array covered with thin films, the contact stress at the interface shifts from compressing to stretching, leading to the formation of more stable and larger nano-liquid bridges and a friction enhancement of about 1.9 times.

Summary: Engineering anti-adhesion coatings typically rely on hierarchical structures and surface free energy to passively remove loosely attached foulants through water scouring. However, highly adhesive or covalently attached foulants are difficult to remove. Inspired by the filtering behavior of Daphnia, a universal antifouling strategy with both passive and active adhesion repellency capabilities is proposed. The liquid-like surface repels general foulants under static conditions and actively prevents the adhesion of highly adhesive foulants under thermal stimuli.
