By rationally designing superhydrophobic electrodes with different underwater wetting states, it is revealed that only the Wenzel-Cassie coexistent state shows clearly enhanced ability in catalyzing oxygen reduction reaction, a typical gas-consuming reaction at electrode. It proposed maximizing and stabilizing liquid/gas/solid triphase interface, endowed by state, plays rather crucial role. As service to our authors readers, this journal provides supporting information supplied authors. Such...

Conventional biological nutrient removal processes rely on external aeration and produce significant carbon dioxide (CO2) emissions. This study constructed a phototrophic simultaneous nitrification-denitrification phosphorus (P-SNDPR) system to treat low nitrogen (C/N) ratios wastewater investigated the impact of sludge retention time (SRT) performance, conversion pathway, microbial structure. Results showed that P-SNDPR at SRT 15 days had highest capacity, achieving over 85% 98% phosphorus,...

Generally, highly efficient liquid transfer is difficult to achieve in open fibrous systems, as compared with traditional closed because capillary coalescence frequently occurs when fiber arrays interact a liquid. Dandelion pappi, which are flexible radial geometries, exhibit the unique ability capture and hold large amounts of water steadily. Drawing inspirations from this natural system, we developed an artificial glass array geometry that capable holding volumes controllably transferring...

Abstract The Plateau–Rayleigh instability (PRI) is a well‐known phenomenon where liquid column always breaks up into droplets to achieve the minimization of surface energy. It normally leads non‐uniformity film, which, however, unfavorable for fluid coating process. So far, strategies overcome this rely on either surfactants, UV/high‐temp curing treatments, or specific chemical reactions, which suffer from both limited composition and complicated experimental conditions. Natural mulberry...

Animal hairs are typical structured conical fibers ubiquitous in natural system that enable the manipulation of low viscosity liquid a well-controlled manner, which serves as fundamental structure Chinese brush for ink delivery controllable manner. Here, drawing inspiration from these structure, we developed dynamic electrochemical method enables fabricating anisotropic multiscale copper wire (SCCW) with conicity and surface morphology. The as-prepared SCCW exhibits unique ability...

Stimuli‐responsive materials, especially those inspired by natural organism, have been extensively studied because of their versatile applications. Here, this study demonstrates that the unique hydroactuated reversible configuration alternation dandelion pappus, featured responsive spatial closing and opening umbrella‐like pappus depending on environmental humidity, is a determining factor allows to regulate its transport behavior. It proposed anisotropic swelling tracheids, which are...
