The shortage of freshwater severely constrains economic development and social security worldwide. Bio-inspired functional fog-harvesting devices (FHDs) have been broadly exploited to tackle this global challenge. Despite the great advances achieved in FHDs, efficient and large-scale water harvesting is still hindered by some inherent limitations: (1) a rational structure should be designed to maximize the function of the separated hydrophilic and hydrophobic regions, (2) simple, low-cost and mature manufacturing technology can better realize the large-scale production of FHDs. Here, inspired by the unique wettability of Namib desert beetles and the wedge-shaped structure of leaf veins, we prepared a dual-biomimetic tuck fabric with a manipulable structure and wettability using knitting technology, which greatly enhanced the fog capture velocity and directional water transportation. The influences of different structures and wettability on fog capture and droplet transportation efficiency have been systematically investigated. Moreover, massive theoretical models were proposed to reveal the fog harvesting mechanism. The optimized FHD exhibited rapid and highly efficient fog harvesting capacity (5424 mg h⁻¹ cm⁻²). In addition, the prepared FHD showed excellent mechanical strength and durability, enabling low-cost and large-scale production. Thus, this work reinforces the understanding of the fundamental research and significantly promotes the practical applications of functional fog-harvesting devices.

The emergence of environmental endocrine disruptor chlorobenzene (CB) in surface water and its potential environmental impacts have attracted serious global attention. It is still very difficult to achieve effective degradation of it by catalytic oxidation process under mild conditions. Here, an optimized method for degrading CB in aqueous solution using Trametes versicolor laccase and surfactant-assisted laccase-mediator (SALM) system was investigated. The use of a Tween 80 surfactant enhanced the solubility of CB and promoted its efficient degradation. Under favorable conditions, the SALM system yielded a degradation efficiency of 43.5% and a dechlorination efficiency of 41.55% for CB (25 mg/L) within 24 h. The possible degradation pathway of CB by this system was speculated by detecting the intermediates produced during the reaction. The outcome of the proliferation assays on MCF-7 human breast cancer cells demonstrated a reduction in the estrogenic activity of the CB solution following treatment with the SALM system. Furthermore, the influence of the quantity and positional variation of chlorine substituents on the degradation process was methodically investigated. Moreover, molecular analyses were employed to study the detailed interaction mechanism between laccase and CB, which revealed that the hydrophobic interaction contributed dominantly to binding process. These findings provide an efficient and environmentally friendly degradation system for the development of purification strategies for halogenated pollutants.
