Main group element‐based materials are emerging catalysts for ammonia (NH3) production via a sustainable electrochemical nitrogen reduction reaction (N2RR) pathway under ambient conditions. However, their N2RR performances are less explored due to the limited active behavior and unclear mechanism. Here, an aluminum‐based defective metal–organic framework (MOF), aluminum‐fumarate (Al‐Fum), is investigated...
Stimulating electron transitions and promoting exciton dissociation are crucial for improving the photocatalytic performance of polymeric carbon nitride (CN) yet still challenging. Herein, a novel CN with C dopant and asymmetric structure (CC‐UCN2) is ingeniously synthesized. The obtained CC‐UCN2 not only reinforces the intrinsic π→π* electron transitions, but also successfully awakens additional...
Sustained oral uncoupler 2,4‐dinitrophenol (DNP) administration exerts prominent anti‐obesity effects, but the adipose tissue off‐target disadvantage leads to systemic adverse effects. A novel non‐cardiotoxicity DNP delivery method using a biocompatible microneedles patch containing the amphiphilic tetradecanoic acid‐DNP ester (TADNP) is described, which is synthesized via esterification on the phenolic...
Increasing the yield of reactive oxygen species (ROS) to enhance oxidative stress in cells is an eternal goal in cancer therapy. In this study, BiVO4 artificial nanozyme is developed with adjustable vanadium vacancy for ultrasound (US) enhanced piezoelectric/sonodynamic therapy. Under US excitation, the vanadium vacancy‐rich BiVO4 nanosheets (abbreviated Vv‐r BiVO4 NSs) facilitate the generation of...
An electrocatalytic methanol oxidation reaction (MOR) is proposed to replace oxygen evolution reaction (OER) in water electrolysis owing to the favorable thermodynamics of MOR than OER. However, there is still a competition between the MOR and the OER when the applied potential is in the conventional OER zone. How to inhibit OER while maintaining efficient MOR is an open and challenging question,...
Lithium‐rich layered oxides (LLOs) are concerned as promising cathode materials for next‐generation lithium‐ion batteries due to their high reversible capacities (larger than 250 mA h g−1). However, LLOs suffer from critical drawbacks, such as irreversible oxygen release, structural degradation, and poor reaction kinetics, which hinder their commercialization. Herein, the local electronic structure...
Nowadays, Fenton chemistry‐based chemodynamic therapy (CDT) is an emerging approach to killing tumor cells by converting endogenous H2O2 into cytotoxic hydroxyl radicals (·OH). However, the elimination of ·OH by intracellular overexpressed glutathione (GSH) results in unsatisfactory antitumor efficiency. In addition, the single mode of consuming GSH and undesirable drug loading efficiency cannot guarantee...
The fluid‐filled cystic cavity sealed by a dense scar developed following traumatic spinal cord injury (SCI) has been a major obstacle to neural regeneration and functional recovery. Here the transected lesion is bridged using a functional self‐assembling peptide (F‐SAP) hydrogel loaded with membrane‐permeable intracellular sigma peptide (ISP) and intracellular LAR peptide (ILP), targeted at perturbing...
Artificial assembly of organic–inorganic heterostructures for electrochemical energy storage at the molecular level is promising, but remains a great challenge. Here, a covalently interlayer‐confined organic (polyaniline [PANI])–inorganic (MoS2) hybrid with a dual charge‐storage mechanism is developed for boosting the reaction kinetics of supercapacitors. Systematic characterizations reveal that PANI...
Thrombotic diseases have a high rate of mortality and disability, and pose a serious threat to global public health. Currently, most thrombolytic drugs especially protein drugs have a short blood‐circulation time, resulting in low thrombolytic efficiency. Therefore, a platelet membrane (Pm) cloaked nanotube (NT‐RGD/Pm) biomimetic delivery system with enhanced thrombolytic efficiency is designed. Nanotubes...
Aqueous Potassium Ion Supercapacitors
A covalently interlayer‐confined polyaniline–MoS2 hybrid with a dual charge storage mechanism is developed for supercapacitors. In the hybrid, confined polyaniline induces a favorable phase transition, facilitates cross‐layer electron transfer, and decreases K+ diffusion barrier, thus enabling high electrochemical performance. More details can be found in article...

In article number 2205260, Fazheng Ren, Yuan Li, and co‐workers developed nature‐inspired platelet membrane‐cloaked nanotubes conjugated with targeting arginine glycine‐aspartic peptide and thrombolytic agent urokinase to achieve clot‐targeting and penetrating. This biomimetic carrier showed a promising effect in improving the thrombolytic efficiency in vitro and...
Due to their marvelous electrical and optical properties, perovskite nanocrystals have reached remarkable landmarks in solar cells, light‐emitting diodes, and photodetectors. However, the intrinsic instability of ionic perovskites, which would undergo an undesirable phase transition and decompose rapidly in ambient humidity, limits their long‐term practical deployment. To address this challenge, halogenated...
The efficiency of reactive oxygen species (ROS)‐mediated cancer therapy is restrained by intrinsic characteristics in the tumor microenvironment (TME), such as overexpressed glutathione (GSH), hypoxia and limited efficiency of H2O2. In this work, intelligent copper‐dropped calcium carbonate loading sonosensitizer Ce6 nanoparticles (Cu/CaCO3@Ce6, CCC NPs) are established to realize TME‐responsive self‐supply...
GaN‐based lateral Schottky barrier diodes (SBDs) have attracted great attention for high‐power applications due to its combined high electron mobility and large critical breakdown field. However, the breakdown voltage (BV) of the SBDs are far from exploiting the material advantages of GaN at present, limiting the desire to use GaN for ultra‐high voltage (UHV) applications. Then, a golden question...

GaN is a promising candidate for next‐generation power electronic devices, but its potential is far from being realized. In article number 2107301, Peng Chen, Rong Zhang, Youdou Zheng, and co‐workers demonstrate a high power figure‐of‐merit, 10.6‐kV AlGaN/GaN lateral Schottky barrier diode with single channel, and sub‐100‐μm anode‐to‐cathode spacing without any other additional...
Phospholipid nanoparticles have been actively employed for numerous biomedical applications. A key factor in ensuring effective and safe applications of these nanomaterials is the regulation of their interactions with target cells, which is significantly dependent on an in‐depth understanding of the nanoparticle‐cell interactions. To date, most studies investigating these nano‐bio interactions have...
To realize excellent selectivity of CH4 in CO2 photoreduction (CO2PR) is highly desirable, yet which is challenging due to the limited active sites for CH4 generation and severe electron‐hole recombination on photocatalysts.

Mild photothermal therapy (PTT, <45 °C) can prevent tumor metastasis and heat damage to normal tissue, compared with traditional PTT (>50 °C). However, its therapeutic efficacy is limited owing to the hypoxic tumor environment and tumor thermoresistance owing to the overproduction of heat shock proteins (HSPs). Herein, a near‐infrared (NIR)‐triggered theranostic nanoplatform (GA‐PB@MONs@LA)...
