The synergistic effect of hollow cavities and multiple hetero‐interfaces displays huge advantages in achieving lightweight and high‐efficient electromagnetic wave absorption, but still confronts huge challenges. Herein, hierarchical Co2P/CoS2@C@MoS2 composites via the self‐sacrificed strategy and a subsequent hydrothermal method have been successfully synthesized. Specifically, ZIF‐67 cores first...
A Zn anode can offset the low energy density of a flow battery for a balanced approach toward electricity storage. Yet, when targeting inexpensive, long‐duration storage, the battery demands a thick Zn deposit in a porous framework, whose heterogeneity triggers frequent dendrite formation and jeopardizes the stability of the battery. Here, Cu foam is transferred into a hierarchical nanoporous electrode...
Strain sensors have been attracting tremendous attention for the promising application of wearable devices in recent years. However, the trade‐off between high resolution, high sensitivity, and broad detection range is a great challenge for the application of strain sensors. Herein, a novel design of hierarchical synergistic structure (HSS) of Au micro cracks and carbon black (CB) nanoparticles is...
Electrochemical Nc reduction has been regarded as one of the most promising approaches to producing ammonia under mild conditions, but there are remaining pressing challenges in improving the reaction rate and efficiency. Herein, an unconventional galvanic replacement reaction is reported to fabricate a unique hierarchical structure composed of Fe3O4‐CeO2 bimetallic nanotubes covered by Fe2O3 ultrathin...
In this study, manganese‐based multiply hierarchical chiral supraparticles (SPs), with an anisotropy factor (g‐factor) of 0.102 and circular dichroism (CD) intensity of 260 mdeg at 530 nm, are successfully synthesized with polar‐solvent‐mediated strategies. Notably, the g‐factor of the SPs is further enhanced to 0.121 by the addition of an external chiral solvent, generating a chiral biased environment,...
Silicon is one of the most promising anode materials for lithium‐ion batteries. However, the huge volume change of silicon during lithiation/delithiation triggers continuous growth of solid‐electrolyte interphase, loss of conductive contacts and structural collapse of the electrode, which causes a rapid deterioration of battery capacities. Inspired by the polyaromatic molecular nature and phase separation...
Microwave Absorption
In article number 2105411, Xiaolong Jia and co‐workers construct a 1D@2D@1D hierarchical structure integrated with multi‐heterointerfaces to boost the microwave absorption efficiency of materials. This design has greatly reduced the threat of electromagnetic pollution caused by the explosive development of communication technology.
Developing microwave absorption (MA) materials with ultrahigh efficiency and facile preparation method remains a challenge. Herein, a superior 1D@2D@1D hierarchical structure integrated with multi‐heterointerfaces via self‐assembly and an autocatalytic pyrolysis is designed to fully unlock the microwave attenuation potential of materials, realizing ultra‐efficient MA performance. By precisely regulating...
Manipulations of carrier and phonon scatterings through hierarchical structures have been proved to be effective in improving thermoelectric performance. Previous efforts in GeTe‐based materials mainly focus on simultaneously optimizing the carrier concentration and band structure. In this work, a synergistic strategy to tailor thermal and electrical transport properties of GeTe by combination with...
A highly stretchable superhydrophobic surface is prepared by Changyu Tang and co‐workers in article number 1602353, through a facile spray‐coating of nano‐carbon black/polybutadiene elastomeric composite on a rubber substrate. The hierarchical roughness of the resulting composite coating exhibits a self‐adaptive deformation behavior and enables the surface to maintain a superhydrophobic property (water...
With the rapid development of stretchable electronics, functional textiles, and flexible sensors, water‐proof protection materials are required to be built on various highly flexible substrates. However, maintaining the antiwetting of superhydrophobic surface under stretching is still a big challenge since the hierarchical structures at hybridized micro‐nanoscales are easily damaged following large...
A simple method to prepare metal‐organic framework (MOF) nanotubes is developed by employing polyoxometalates (POMs) as modulators. The local structure of the MOF nanotubes is investigated combining XANES and EXAFS studies. These nanotubes show both an excellent catalytic performance in the detoxification of sulfur compounds in O2 atmosphere and a remarkable cycling stability as the anode material...
