The pursuit of high‐performance batteries has propelled the investigation into advanced materials and design methodologies. Herein, the yolk‐shell MnSe/ZnSe heterojunction encapsulated in hollow carbontubes (MnSe/ZnSe@HCTs) is prepared as a prospective electrode material for sodium/potassium batteries. The band structure in the heterojunction is methodically adjusted and regulated by intentionally...
With the rapid development of performance and long‐term stability, bismuth vanadate (BiVO4) has emerged as the preferred photoanode in photoelectrochemical tandem devices. Although state‐of‐the‐art BiVO4 photoanodes realize a saturated photocurrent density approaching the theoretical maximum, the fill factor (FF) is still inferior, pulling down the half‐cell applied bias photon‐to‐current efficiency...
Silicon (Si) is considered a promising commercial material for the next‐generation of high‐energy density lithium‐ion battery (LIB) due to its high theoretical capacity. However, the severe volume changes and the poor conductivity hinder the practical application of Si anode. Herein, a novel core–shell heterostructure, Si as the core and V3O4@C as the shell (Si@V3O4@C), is proposed by a facile solvothermal...
Amorphous alloys have multiple advantages in electrocatalysis, yet the isotropic nature makes their syntheses a great obstacle in application. In this work, it is shown that the Zn2+ can interfere with the crystallization of Pd‐base structures to form amorphous alloy materials. By simply adjusting the Zn2+ content, unique PdZnS amorphous hollow spheres (AHS) with various compositions and degrees of...
Twisting has recently been demonstrated as an effective strategy for tuning the interactions between particles or quasi‐particles in layered materials. Motivated by the recent experimental synthesis of pentagonal NiN2 sheet [ACS Nano 2021, 15, 13539], for the first time, the response of phonon coherence to twisting in bilayer penta‐NiN2, going beyond the particle‐like phonon transport is studied....
Constructing wrinkled structures on the surface of materials to obtain new functions has broad application prospects. Here a generalized method is reported to fabricate multi‐scale and diverse‐dimensional oxide wrinkles on liquid metal surfaces by an electrochemical anodization method. The oxide film on the surface of the liquid metal is successfully thickened to hundreds of nanometers by electrochemical...
Chemodynamic therapy (CDT) utilizes Fenton or Fenton‐like reactions to convert hydrogen peroxide (H2O2) into cytotoxic hydroxyl radicals (•OH) and draws extensive interest in tumor therapy. Nevertheless, high concentrations of glutathione (GSH) and insufficient endogenous H2O2 often cause unsatisfactory therapeutic efficacy. Herein, a GSH‐depleting and H2O2 self‐providing carrier‐free nanomedicine...
High‐performance X‐ray detectors have immense potential in medical and security inspections. However, the current X‐ray detectors are limited in flexible, high‐spatial‐resolution large‐scale detection, and integration for imaging. Here, nuclear track‐etched porous polyethylene terephthalate (PET) is developed as the template for preparing uniform, large‐area (≥105 cm2), and flexible metal halide (MH)‐based...
Poor selectivity and unintended toxicity to normal organs are major challenges in calcium ion (Ca2+) overload tumor therapy. To address this issue, a cell membrane‐anchoring nano‐photosensitizer (CMA‐nPS) is constructed for inducing tumor‐specific Ca2+ overload through multistage endogenous Ca2+ homeostasis disruption under light guidance, i.e., the extracellular Ca2+ influx caused by cell membrane...

In article number 2204689, Xiaoqing Yi, Gengyun Sun, Xiaoyan He, and co‐workers develop a cell membrane‐anchoring nano‐photosensitizer (CMA‐nPS) based on genetically engineered cellular membrane vesicles. The nano‐photosensitizer significantly induces intercellular Ca2+ overload through multistage endogenous homeostasis disruption under laser irradiation. With an obvious synergistic...
Lattice distortions and defects can lead to a strain effect that greatly affects the electronic structure of the noble metal surface and the chemical adsorption of ligands on the surfaces. Introducing defects is an efficient strategy to improve the activity of noble metal catalysts. Herein, a fusion approach is developed to fine‐tune the defects and lattice strain in Au–Pd nanowires. Specifically,...

In article number 2108090, Gang Wang, Hao‐Li Zhang, Zhiwen Jin, and co‐workers propose a C3N quantum dots insertion method to effectively adsorb bulky organic cations, and provide nucleation sites to realize gradient distribution of solute in 2D CsPbI3 film to obtain a bi‐directional crystallization process. Importantly, the optimized 2D CsPbI3 film‐based device delivers a high power conversion...
Two‐dimensional (2D) CsPbI3 is developed to conquer the phase‐stability problem of CsPbI3 by introducing bulky organic cations to produce a steric hindrance effect. However, organic cations also inevitably increase the formation energy and difficulty in crystallization kinetics regulation. Such poor crystallization process modulation of 2D CsPbI3 leads to disordered phase‐arrangement, which impedes...
Tailoring the structure of metal components and interaction with their anchored substrates is essential for improving the catalytic performance of supported metal catalysts; the ideal catalytic configuration, especially down to the range of atomic layers, clusters, and even single atoms, remains a subject under intensive study. Here, an Ir‐on‐MXene (Mo2TiC2Tx) catalyst with controlled morphology changing...
It is extremely important to develop a high energy density power source with rapid charge–discharge rate to meet people's growing needs. Hence, the development of advanced electrode materials is the top priority. Herein, a simple yet elaborate vacuum‐assisted room‐temperature phase transfer method is reported to transform MXene nanosheets from water into organic solution. Subsequently, an in‐situ...
While bimetallic 2D metallic nanomaterials are widely synthesized and used as electrocatalysts with enhanced performance, trimetallic 2D structures are less commonly reported. In this work, a facile wet chemical method for synthesizing Pd nanosheets and PdPtNi trimetallic alloy nanosheets is developed. Without the introduction of gaseous CO and pressurized equipment, Pd nanosheets with a thickness...
Transition‐metal phosphides have flourished as promising candidates for oxygen evolution reaction (OER) electrocatalysts. Herein, it is demonstrated that the electrocatalytic OER performance of CoP can be greatly improved by constructing a hybrid CoP/TiOx heterostructure. The CoP/TiOx heterostructure is fabricated using metal–organic framework nanocrystals as templates, which leads to unique hollow...
A new conceptual injectable and radiopaque liquid metal/calcium alginate (LM/CA) hydrogel is proposed and demonstrated in article number 1903421 by Jing Liu and co‐workers for endovascular embolization and tumor embolotherapy. It is shown that such a hydrogel displays high flexibility and radiopacity due to the introduction of LM droplets. It also owns excellent biocompatibility and hemocompatibility...
Improved endovascular embolization can contribute to assistant treatment for patients. However, many traditional embolic materials, such as metal microcoils or liquid embolic agents, are associated with limitations of coil migration or recanalization. Herein, as the first trial, an injectable and radiopaque liquid metal/calcium alginate (LM/CA) hydrogel is introduced and fabricated as a candidate...
Refractory periapical periodontitis, which is a persistent infection after root canal treatment, still has no effective treatment. Its most common pathogen is Enterococcus faecalis. Here, the precursor of phytosteroids, dioscin, is introduced to fight against the inflammation induced by Enterococcus faecalis. The findings suggest that dioscin inhibits the nuclear transport of NF‐κB and the expression...
