ABSTRACT MXene‐based nanomaterials are showing great potential in the biomedicine field, and particularly, they have already stood out to detect and eradicate the bacterial contamination/infection. This review started with the basic perception of MXene, and systematically described the structure, properties, preparation, and functionalization. Then MXene‐based nanomaterials were explored towards …

ABSTRACT Efficient radiative cooling requires an unobstructed view of the sky. However, the vertical facades of buildings see terrestrial features, which act as broadband infrared emitters of heat in the summer. As a result, for conventional materials, including building windows, terrestrial heat gain in the summer can negate or overwhelm a vertically‐oriented surface's narrowband long‐wave infra…

ABSTRACT Wearable electronics show promise in advancing personalized healthcare, with electronic skins (e‐skins) emerging as ideal candidates due to their intimate skin conformability. However, their widespread adoption is constrained by complex fabrication, insufficient conformability, and suboptimal biocompatibility. Herein, we propose a poly(lipoic acid)‐based sprayable electronic tattoo (LS e…

ABSTRACT Understanding droplet‐liquid pool interactions in immiscible systems is critical for advancing fluidic encapsulation strategies. Here, we uncover a previously unreported ‘endocytosis’ phenomenon in which an aqueous droplet impacts a deep immiscible pool and spontaneously engulfs the pool liquid, forming a stable double‐layered liquid structure. This process origins from the focusing of c…

ABSTRACT Aqueous zinc‐ion batteries (AZIBs) suffer from poor Zn anode stability in aqueous electrolytes, arising from disordered Zn deposition and parasitic reactions. While artificial solid electrolyte interfaces mitigate these issues, their fabrication is complex and time‐consuming. In this study, an ultrafast chemical solution reaction and selective etching are designed to in situ exfoliate a …

ABSTRACT UOR/OER bifunctional catalysts are essential to environmental remediation and hydrogen production from industrial wastewater with varied urea concentrations. Although a few studies attempt on catalysts with adaptive active centers for varying urea concentration, urea decomposition is inhibited when urea is adsorbed on OER‐active phase with UOR‐inertness. It can result in incomplete urea …

ABSTRACT Developing electromagnetic (EM) pyramidal absorbers that maintain stable, efficient, and broadband EM absorption in extreme high temperature environments is a critical yet challenging objective for advanced stealth technologies. Inspired by the anti‐reflection structure of moth eyes, this work proposes complex pyramidal absorbers based on a multicomponent polymer derived ceramic composed…

ABSTRACT Immunotherapy has revolutionized antitumor treatment, but its effectiveness is severely compromised by the immunosuppressive tumor microenvironment (TME) and inadequate induction of antitumor immune responses, with most solid tumors remaining immunologically “cold” and unresponsive to monotherapies. Mitoxantrone (MTO), a first‐line chemotherapeutic agent, is additionally limited by poor …

ABSTRACT Bifunctional electrocatalysts simultaneously applicable for oxygen evolution reaction (OER) and urea oxidation reaction (UOR) remain limited by intrinsic active‐site incompatibility and competitive intermediate adsorption. High‐valence metal centers are required for lattice oxygen activation during OER, whereas low‐valence metallic sites are favorable for urea coordination and C─N bond c…

ABSTRACT The rational design of acid‐stable, iridium‐free electrocatalysts for the oxygen evolution reaction (OER) is critical for advancing proton exchange membrane water electrolysis (PEMWE), yet balancing activity and durability remains a formidable challenge. Herein, we report a RuO 2 /Mn 3 O 4 heterojunction with engineered oxygen vacancies (O v ) as a durable, high‐performance iridium alter…

ABSTRACT Aluminum‐ion capacitors (AICs) attract significant research interest as multivalent energy‐storage devices that aim to increase energy density beyond that of conventional monovalent‐ion supercapacitors. Owing to the trivalent charge of Al 3+ and the abundance, low cost, and relative chemical stability of aluminum, AICs hold strong potential for sustainable and scalable energy storage. Th…

ABSTRACT Antimony selenide (Sb 2 Se 3 ) solar cells have attracted considerable attention owing to their excellent optoelectronic properties. However, their efficiency remains severely limited by non‐radiative recombination. To address this issue, previous studies have mainly focused on crystal orientation, defect passivation, and interfacial energy‐level alignment. Nevertheless, the role of stra…

ABSTRACT Catalyzing polysulfides conversion is essential for mitigating the shuttle effect and sluggish kinetics in lithium‐sulfur (Li‐S) batteries, yet single‐component catalysts struggle to sustain activity throughout the complex sulfur redox process. Herein, a nanoflower‐structured CoS/Co 9 S 8 heterojunction derived from a MOF template is designed as an advanced sulfur host. The built‐in elec…

ABSTRACT Beam‐induced chemistry in liquid‐phase imaging is now recognized as a key factor in interpreting nanoscale redox processes, yet its consequences depend strongly on the irradiation modality, solvent chemistry, and reacting material system. Here, we compare how soft X‐ray and electron irradiation redirect the same galvanic replacement reaction between Cu 2 O nanocubes and gold precursors. …

ABSTRACT Ruthenium oxide (RuO 2 ) is the most promising alternative to iridium oxide (IrO 2 ) catalyst in proton‐exchange‐membrane water electrolysis (PEMWE). However, its practical application has been hindered by poor stability. Here, we developed an interface‐growth‐assisted molten salt synthesis (MSS) strategy for the preparation of stable cobalt (Co)‐embedded RuO 2 (Co‐RuO 2 ) nanorods using…

ABSTRACT Pancreatic ductal adenocarcinoma (PDAC) is among the deadliest malignancies, due to late diagnosis, poor therapeutic response, and high inter‐ and intra‐patient heterogeneity. Metabolic alterations, particularly extracellular acidification, critically impair drug response yet remain underexplored in clinical stratification. We present a sensing‐integrated 3D platform that enables non‐inv…

ABSTRACT Chemically active droplets at fluid interfaces provide versatile building blocks for dynamic matter, yet most systems are limited to behavior encoded within individual droplets or simple pairwise interactions. Here, we report a strategy to generate non‐linear, cascading behavior in droplet swarms by combining photo‐activation with synergistic solvation of surfactants. At an air/water int…

ABSTRACT Lithium metal anodes are pivotal for next‐generation high‐energy batteries, yet practical deployment is severely limited by rampant dendrite growth, fragile solid‐electrolyte interphase (SEI), and drastic volume expansion under high‐areal‐capacity and lean‐electrolyte industrial conditions. Conventional porous carbon hosts suffer from disordered pore geometry and tortuous ion transport, …

ABSTRACT Solving the morphological complexity of nanomaterials such as silver nanoparticles, at the one‐atom level, is a prerequisite to reach a rational design of their properties. To date, structural measurements in ultra‐high vacuum of silver nanoparticles remain uninterpreted. The narrow competition between octahedra and decahedra evolves in morphological statistics in the range 309–923 atoms…

ABSTRACT Nanozymes are engineered nanomaterials possessing intrinsic enzyme‐mimetic catalytic activities that enable regulation of reactive oxygen species (ROS). Initially developed for superoxide dismutase‐, catalase‐, and peroxidase‐like antioxidant functions, nanozymes are increasingly recognized as modulators of immune responses through redox‐dependent mechanisms. Given that ROS participate i…
