The demand for high‐performance and cost‐effective energy storage solutions for mobile electronic devices and electric vehicles has been a driving force for technological advancements. Among the various options available, transitional metal oxides (TMOs) have emerged as a promising candidates due to their exceptional energy storage capabilities and affordability. In particular, TMO nanoporous arrays...
Three‐dimensional (3D) structures constructed via coordination‐driven self‐assemblies have recently garnered increasing attention due to the challenges in structural design and potential applications. In particular, developing new strategy for the convenient and precise self‐assemblies of 3D supramolecular structures is of utmost interest. Introducing the concept of self‐coordination ligands, herein...
Acute lung injury (ALI)/acute respiratory distress syndrome (ARDS) is a common respiratory critical syndrome that currently has no effective therapeutic interventions. Pulmonary macrophages play a principal role in the initiation and progression of the overwhelming inflammation in ALI/ARDS. Here, a type of fluorous‐tagged bioactive peptide nanoparticle termed CFF13F is developed, which can be efficiently...
Electrochemical (EC) actuators have garnered significant attention in recent years, yet there are still some critical challenges to limit their application range, such as responsive time, multifunctionality, and actuating direction. Herein, an EC actuator with a back‐to‐back structure is fabricated by stacking two membranes with bilayer V2O5 nanowires/single‐walled carbon nanotubes (V2O5 NWs/SWCNTs)...
Reasonable design of electrode materials with specific morphology and structure can efficiently improve the metal ions storage and transmission properties of metal ion batteries.

Three‐dimensional spirobifluorene‐based carbiyne nanospheres (SBFCY‐NSs) are prepared by Jinchong Xiao, Jianjiang He, Changshui Huang, and co‐workers in article number 2106328. The rationally designed chemical structure contributes to the formation of an ion diffusion pathway protected by a robust solid electrolyte interface film in a lithium ion battery.
Simultaneous boosting electrochemical methanol oxidation reaction (MOR) for direct methanol fuel cells and production of hydrogen is meaningful but challenging. Herein, a sea urchin‐shaped cobalt‐embedded N‐doped carbon nanotubes (Co@NCNT) encapsulated CoPt3@Co2P heterojunction (CoPt3@Co2P/Co@NCNT) is fabricated. Theoretical calculations confirm that electrons at the interfaces transfer from CoPt3...

Metal–organic frameworks (MOFs) have attracted enormous research interest as precursors/templates to prepare catalytic materials. However, the effect of structural isomerism of MOFs on the catalytic performance has rarely been studied. In this contribution, two topologically different Ce‐benzene tricarboxylate (Ce‐BTC) based on the same ligands and metal centers (viz., “MOF isomers”) are prepared...
In article number 1907013, Changshui Huang and co‐workers directly prepare the methyl substituted graphdiyne nanothorn arrays (MGDY NTAs) on a variety of substrates by a one‐step method, which shows superhydrophobic properties, and high durability. The MGDY NTAs can be applied in the fields of metal corrosion protection and oil–water separation.
This study proposes a one‐step method for growing superhydrophobic carbon nanothorn arrays (NTAs) directly on various substrates. The fabricated carbon material (named methyl‐substituted graphdiyne (MGDY)) comprises sp and sp2 carbons in a conjugated‐backbone form, as well as methyl groups introduced into the framework as hydrophobic‐enhanced functional groups. MGDY NTAs exhibit excellent hydrophobicity...
Oxygen evolution reaction (OER) is of great significance for hydrogen production via water electrolysis, which, however, demands development of highly active, durable, and cost‐effective electrocatalysts in order to stride into a renewable energy era. Herein, highly efficient and long‐term durable OER by coupling B and P into an amorphous porous NiFe‐based electrocatalyst is reported, which possesses...
For mechanically protective coatings, the coating material usually requires sufficient stiffness and strength to resist external forces and meanwhile matched mechanical properties with the underneath substrate to maintain the structural integrity. These requirements generate a conflict that limits the coatings from achieving simultaneous surface properties (e.g., high wear‐resistance) and coating/substrate...
In article number 1802717, Zhengzhi Wang, Houbing Huang, Zuoqi Zhang, and co‐workers develop functional gradient nanocomposite coatings with hybrid‐sized nanoreinforcements gradiently and discretely distributed towards the coating surface. The coatings exhibit simultaneously high surface hardness, stiffness, and wear resistance, as well as superb coating/substrate interfacial integrity that applies...
