The free radical generation efficiency of nanozymes in cancer therapy is crucial, but current methods fall short. Alloy nanoparticles (ANs) hold promise for improving catalytic performance due to their inherent electronic effect, but there are limited ways to modulate this effect. Here, a self‐driven electric field (E) system utilizing triboelectric nanogenerator (TENG) and AuPd ANs with glucose oxidase...
The patient‐centered healthcare requires timely disease diagnosis and prognostic assessment, calling for individualized physiological monitoring. To assess the postoperative hemodynamic status of patients, implantable blood flow monitoring devices are highly expected to deliver real time, long‐term, sensitive, and reliable hemodynamic signals, which can accurately reflect multiple physiological conditions...
High‐quality photodetectors are always the main way to obtain external information, especially near‐infrared sensors play an important role in remote sensing communication. However, due to the limitation of Silicon (Si) wide bandgap and the incompatibility of most near infrared photoelectric materials with traditional integrated circuits, the development of high performance and wide detection spectrum...
Developing efficient and durable electrocatalysts for the oxygen evolution reaction (OER) in proton exchange membrane (PEM) electrolyzers represents a significant challenge. Herein, the cobalt‐ruthenium oxide nano‐heterostructures are successfully synthesized on carbon cloth (CoOx/RuOx‐CC) for acidic OER through a simple and fast solution combustion strategy. The rapid oxidation process endows CoO...
Stereopsis is of great important functions for humans to perceive and interact with the world. To realize the function of stereoscopic imaging, optoelectronic sensors shall possess good photoresponsive performance, multidirectional sensing, and 3D building capabilities. However, the current imaging sensors are mainly focused on 2D imaging, limiting their practical application scenarios. In this study,...
Sonodynamic therapy (SDT) is regarded as a new‐rising strategy for cancer treatment with low invasiveness and high tissue penetration, but the scarcity of high‐efficiency sonosensitizers has seriously hindered its application. Herein, the iron‐doped and oxygen‐deficient bismuth tungstate nanosheets (BWO‐Fe NSs) with piezotronic effect are synthesized for enhanced SDT. Due to the existence of oxygen...
Since the sluggish kinetic process of oxygen reduction (ORR)/evolution (OER) reactions, the design of highly‐efficient, robust, and cost‐effective catalysts for flexible metal–air batteries is desired but challenging. Herein, bimetallic nanoparticles encapsulated in the N‐doped hollow carbon nanocubes (e.g., FeCo‐NPs/NC, FeNi‐NPs/NC, and CoNi‐NPs/NC) are rationally designed via a general heat‐treatment...
Current photocatalytic semiconductors often have low catalytic performance due to limited light utilization and fast charge carrier recombination. Formation of Schottky junction between semiconductors and plasmonic metals can broaden the light absorption and facilitate the photon‐generated carriers separation. To further amplify the catalytic performance, herein, an asymmetric gold‐zinc oxide (Asy‐Au−ZnO)...
In the scenario of renewable clean energy gradually replacing fossil energy, grid‐scale energy storage systems are urgently necessary, where Na‐ion batteries (SIBs) could supply crucial support, due to abundant Na raw materials and a similar electrochemical mechanism to Li‐ion batteries. The limited energy density is one of the major challenges hindering the commercialization of SIBs. Alloy‐type anodes...

Self‐powered UV photodetectors based on TiO2 nanotree arrays have captured much attention in recent years because of their many advantages. In this work, rutile/anatase TiO2 (R/A‐TiO2) heterostructured nanotree arrays are fabricated by assembling anatase nanowires as branches on rutile nanorods. External quantum efficiencies as high as 90% are reached at 325 nm. These high quantum efficiencies are...
Exploitation of high‐performance anode materials is essential but challenging to the development of sodium‐ion batteries (SIBs). Among all proposed anode materials for SIBs, sulfides have been proved promising candidates due to their unique chemical and physical properties. In this work, a facile solvothermal method to in situ decorate cobalt sulfide (CoS) nanoplates on reduced graphene oxide (rGO)...
