Bioinspired surfaces with superwettability have attracted great interest in both fundamental research and industry applications. Recent progress in superhydrophobic TiO2‐based surfaces with high contrast in solid/liquid adhesion is reviewed on page 2203 by Y. K. Lai, L. F. Chi and co‐workers. In addition, the significant applications related to super‐wetting/antiwetting surfaces with controllable...
Bioinspired surfaces with special wettability and adhesion have attracted great interest in both fundamental research and industry applications. Various kinds of special wetting surfaces have been constructed by adjusting the topographical structure and chemical composition. Here, recent progress of the artificial superhydrophobic surfaces with high contrast in solid/liquid adhesion has been reviewed,...
Designing smart surfaces with tunable wettability has drawn much attention in recent years for academic research and practical applications. Most of the previous methods to achieve such surfaces demand some particular materials that inherently have special features or complicated structures which are usually not easy to obtain. A novel strategy to achieve such smart surfaces is proposed by using the...
Nowadays, the pollution of water has become worse in many parts of the world, which causes a severe shortage of clean water and attracts widespread attention worldwide. Bioinspired from nature, i.e. spider silk, cactus, Namib desert beetle, Nepenthes alata, special wettability surfaces have attracted great interest from fundamental research to water‐harvesting applications. Here, recently published...
Heterostructured microfibers with spindle‐knots and joints are developed using a novel microfluidic technology, which enables integrative microfiber joint spinning, fluid coating, and knot emulsification. The knots emulsification process can be precisely tunable by adjusting the flow rates. In this way, the size and spacing of the spindle‐knots of the microfibers can be achieved with high controllability...
The separation of organic liquid mixtures is achieved by Cu(OH)2 nanoneedle‐covered copper mesh based on the difference of the liquid surface tension. The as‐prepared membrane allows the penetration of organic liquid with smaller surface tension and blocks the higher. Thus, the effective separation of these two organic liquids can be achieved.
With the impacts of climate change and impending crisis of clean drinking water, designing functional materials for water harvesting from fog with large water capacity has received much attention in recent years. Nature has evolved different strategies for surviving dry, arid, and xeric conditions. Nature is a school for human beings. In this contribution, inspired by the Stenocara beetle, superhydrophilic/superhydrophobic...
The high‐performance electrode materials with tuned surface and interface structure and functionalities are highly demanded for advanced supercapacitors. A novel strategy is presented to conFigure high‐stacking‐density, superior‐roughness nickel manganese layered double hydroxide (LDH) bridged by vertically aligned graphene (VG) with nickel foam (NF) as the conductive collector, yielding the LDH‐NF@VG...
In article number 1701288, by Chang Yu, Jieshan Qiu, and co‐workers, high‐stacking‐density, superior‐roughness layered double hydroxide (LDH) bridged with vertically aligned graphene (VG) is rationally designed and successfully configured. The VG nanosheets are capable of promoting mass and electron transfer, and high‐stacking‐density LDH induces a superior hydrophilic behavior, thus leading to a...
To achieve an excellent delivery effect of drug, stimuli‐responsive nano “gate” with physical blockage units is usually constructed on the surface of the mesoporous silica nanocarriers (MSNs). In nature, the aquaporins in cell membrane can control the transport of water molecules by regulating the channel wettability, which is resulted from the conformational change of amino acids in the channel....
Ice accumulation poses a series of severe issues in daily life. Inspired by the nature, superwettability surfaces have attracted great interests from fundamental research to anti‐icing and ice‐phobic applications. Here, recently published literature about the mechanism of ice prevention is reviewed, with a focus on the anti‐icing and ice‐phobic mechanisms, encompassing the behavior of condensate microdrops...
Solution‐processed semiconductor single‐crystal patterns possess unique advantages of large scale and low cost, leading to potential applications toward high‐performance optoelectronic devices. To integrate organic semiconductor micro/nanostructures into devices, various patterning techniques have been developed. However, previous patterning techniques suffer from trade‐offs between precision, scalability,...
Higher order emulsions are used in a variety of different applications in biomedicine, biological studies, cosmetics, and the food industry. Conventional droplet generation platforms for making higher order emulsions use organic solvents as the continuous phase, which is not biocompatible and as a result, further washing steps are required to remove the toxic continuous phase. Recently, droplet generation...
To achieve clean and high‐efficiency utilization of renewable energy, functional surfaces with controllable and patternable wettability are becoming a fast‐growing research focus.

Using the laser raster‐scanning and vector‐scanning modes, two distinct...
Liquid lubricant of low affinity makes slippery coatings widely used in lubricating, anti‐biofouling, anti‐icing, fluid guiding, and drag reduction. Two critical challenges, however, remain in the practical application of slippery coatings consisting of liquid lubricants: (1) universality regardless of roughness and chemical composition of substrates, (2) stability of surface lubricity against evaporation...
Inverted perovskite solar cells (IPSCs) have witnessed an impressive development in recent years. However, their efficiency is still significantly behind theoretical limits, and device instabilities hinder their commercialization. Two main obstacles to further enhancing their performance via one‐step deposition are: 1) the unsatisfactory film quality of perovskite and 2) the poor surface contact....
Droplet friction is common and significant in any field where liquids interact with solid surfaces. This study explores the molecular capping of surface‐tethered, liquid‐like polydimethylsiloxane (PDMS) brushes and its substantial effect on droplet friction and liquid repellency. By exchanging polymer chain terminal silanol groups for methyls using a single‐step vapor phase reaction, the contact line...
Liquid metal batteries (LMBs) are promising candidates for grid‐scale energy storage due to their exceptional kinetics, scalability, and long lifespan derived from the distinctive three‐liquid‐layer structure. However, the positive electrode (such as Bi) suffers from insufficient wettability on the current collector, resulting in excess electrical resistance and uneven current distribution, thus deteriorating...
