ABSTRACT Phototherapy offers a non‐pharmacological modality for wound repair used in routine clinical practice. However, the wavelength‐dependent absorption and scattering within the skin markedly attenuate the penetration depth of visible light at the therapeutic target. Herein, we develop a strain‐programmable luminescent adhesive patch with tartrazine (Tar)‐mediated optical skin clearing for photochemical tissue bonding (PTB). Hyaluronic acid (HA) facilitates the transdermal delivery of Tar to improve optical skin clearing and stabilizes its interaction with a photosensitizer. Optical skin clearing increases the visible‐light penetration into skin tissues and the patch mechanically contracts the wound gap while emitting sustained green luminescence to photoactivate rose bengal (RB) for collagen crosslinking. In a murine incisional wound model, a single treatment accelerates collagen fibrillogenesis, increases interfacial tensile strength, and produces continuous wound‐edge apposition with organized collagen deposition and modulated inflammatory markers. These findings point to a practical application to light‐based wound sealing that complements sutures and would open a big avenue for further biophotonic applications in dermatology and tissue regeneration.

ABSTRACT Ni‐rich layered oxide cathodes, regarded as promising high‐energy‐density cathode materials for lithium‐ion batteries, still suffer from electrochemical performance degradation during cycling, primarily due to structural phase transitions and particle cracking. Although doping and surface coating are widely adopted modification strategies, such treatments are typically performed in air or oxygen‐containing atmospheres, leaving the effects of oxygen‐free environments largely unexplored. In this work, we systematically investigate the relationship between structural evolution and electrochemical performance of Ni‐rich cathodes modified under an oxygen‐free atmosphere. Notably, by precisely controlling the surface oxygen vacancies, an in situ layered‐spinel coherent coating is formed on the particle surface. This hybrid structure effectively increases the energy barrier for further oxygen vacancy formation, suppresses surface Ni─O reactivity, and stabilizes lattice oxygen, thereby significantly enhancing the high‐voltage cycling stability. After calcination at 200°C for 5 h in an argon atmosphere, the modified cathode exhibits a capacity retention of 83.6% after 200 cycles at 4.6 V, markedly improved from 69.1% for the pristine electrode. This study offers an innovative and effective strategy for stabilizing high‐voltage Ni‐rich layered oxide cathodes through atmosphere‐controlled surface engineering.

ABSTRACT Psoriasis is a chronic inflammatory skin disease driven by oxidative stress, necessitating advanced antioxidant nanozymes capable of broad‐spectrum reactive oxygen species (ROS) elimination. Here, we address this challenge through the rational design of a ternary synergistic nanocluster, Ag 14–20 Au 5–11 @FeTP, engineered via “atomic engineering” of an optimal AgAu alloy core and “molecular engineering” via Fe‑porphyrin ligand grafting. This dual‐level engineering creates a metal–ligand synergistic interface that confers excellent multi‐enzyme mimetic activity for scavenging H 2 O 2 , •O 2 − , and •OH. Coupled with enhanced skin penetration, the nanozyme demonstrates both therapeutic and preventive efficacy in a psoriasis mouse model, rivaling the first‐line clinical drug betamethasone/calcipotriol, without observable systemic toxicity. Transcriptomic profiling reveals that its potent effect originates from a dual‐pathway immunomodulation: simultaneous suppression of the pro‐inflammatory IL‑23/Th17/IL‑17 and NF‑κB axes and enhancement of the anti‐inflammatory Treg/Th2 pathways. This work establishes a generalizable “precision synergy” paradigm for designing high‐performance nanocluster‐based therapeutics against oxidative stress‐related inflammatory diseases.

ABSTRACT Photothermal CO 2 conversion into value‐added syngas via dry reforming is pivotal for greenhouse gas utilization, yet its efficiency is constrained by catalyst deactivation. Here, we demonstrate that morphology‐induced crystal phase modulation of ZrO 2 supports enables effective optimization of interfacial sites in Ni/ZrO 2 catalysts. By engineering cubic (Ni/ZrO 2 ‐C) and stellated (Ni/ZrO 2 ‐S) architectures, a metastable mixed‐phase structure (54.8% monoclinic/37.3% tetragonal) is stabilized to achieve precise phase regulation. Systematic characterization reveals that this phase transformation strengthens metal–support interactions, improves Ni dispersion, and generates abundant oxygen vacancies. As a result, Ni/ZrO 2 ‐C achieves 95% ethanol conversion with lower by‐product formation and exhibits exceptional stability, with a 50% lower deactivation rate (0.13% h −1 ) than Ni/ZrO 2 ‐S (0.26% h −1 ). The enhanced performance is attributed to improved surface basicity and more efficient coke gasification facilitated by interfacial oxygen vacancies. ​Theoretical calculations further confirm kinetically favorable pathways with reduced activation barriers, particularly for carbon oxidation, accounting for the observed 3.2‐fold higher activity of Ni/ZrO 2 ‐C. This work establishes morphology‐directed crystal phase engineering as a general strategy for designing efficient photothermal catalysts.

ABSTRACT In several fluid flow, energy‐dumping, and energy‐harvesting applications, a dominant flow direction or dominant resistance direction is desirable. In this study, we propose a simple modular geometry that doubles flow resistance in one direction relative to the opposite direction, while maintaining laminar viscous flow. We analyze planar two‐component Particle Image Velocimetry results to investigate flow characteristics in the two opposing principal flow directions and to evaluate the relationship between the flow patterns and the observed macroscopic flow resistances. It was observed that, in a manner similar to observations in other asymmetric incompressible viscous flows, inertial phenomena contribute to the breaking of reciprocity. Some geometrical variations are also explored, providing an overview of the importance of different flow features in determining flow resistance. Low flow resistance is observed in continuous‐flow streams, whereas high flow resistance is associated with jet production and dissipation. Ideally, these two situations correspond to the favorable and unfavorable flow directions, respectively, resulting in a large pressure drop difference between them, as observed in some of the tested geometries. We have also observed, in the higher‐velocity studies, the emergence of a symmetry‐breaking flow structure that gives rise to a new flow pattern with alternating jet deflections.

ABSTRACT Sn‐Pb mixed perovskite solar cells (PSCs) have attracted broad attention due to their higher theoretical power conversion efficiency (PCE). However, organic materials, including poly (3,4‐ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) are still commonly used as the hole transport layer (HTL) in this field, it leads to poor stability in Sn‐Pb mixed PSCs. In this work, we introduce a p‐type SnO x (0 < x< 2) as hole transport layer, boosting both the efficiency and stability of Sn‐Pb mixed PSCs. The unique successive hemispherical protrusions‐like morphology markedly improves the interfacial contact with the perovskite layer, resulting in enhanced carrier extraction, efficient transport and distinctive modulation of light absorption. Meanwhile, the perovskite crystallinity is greatly enhanced with suppressed oxidation of Sn(II), and the photovoltaic performance is greatly improved. Finally, we achieve a champion PCE of 23.71% for Sn‐Pb mixed PSCs, breaking the record for fully‐inorganic‐HTL‐based Sn‐Pb mixed PSCs. The device retains 90% of its initial efficiency after operating at the maximum power point for 1105 h, indicating a marked improvement in stability among the reports of best stability. This effective inorganic hole transport material provides a new research strategy for Sn‐Pb perovskite optoelectronic devices.

ABSTRACT Donor‐acceptor (D‐A) conjugated materials based on molecular motion have potential advantages in solar‐thermal conversion technology due to their capability to significantly enhance photothermal conversion efficiency. However, resolving the inherent balance between conjugation extension and molecular motion in organic D‐A materials remains a key challenge. Herein, we present an innovative design strategy for constructing high‐performance solar‐thermal materials: a) D‐A conjugated backbone constructed with [1,2,5]thiadiazolo[3,4‐g]quinoxaline‐6,7‐dicarboxylate (BTQ) and various thiophene‐based donor units enable enhanced intramolecular charge transfer; b) long alkyl chains incorporated into D‐A backbone afford more intramolecular rotational space for polymers; c) donor units screened for optimal volume and conjugation degree weigh conjugation extension against group rotation. The objective is to develop materials exhibiting excellent solar spectrum matching while elucidating the mechanism of efficient solar‐thermal conversion. Therefore, three narrow bandgap conjugated polymers PT‐BTQ, PTT‐BTQ, and PIDT‐BTQ are synthesized. Among them, PTT‐BTQ has the widest spectral absorption of 300–2000 nm and the photothermal conversion efficiency of 20.20%. Furthermore, a multifunctional solar‐thermal thermoresponsive hydrogel (STH‐TT) is prepared, which can achieve a remarkable total water collection rate of 9.78 kg m −2 h −1 under one sun irradiation. Moreover, a lightweight and portable sewage purifier is developed to solve the problem of freshwater scarcity in extreme environments.

ABSTRACT Achieving near‐zero thermal expansion (NZTE) in single‐phase materials over broad temperature ranges is crucial yet challenging for precision applications. Here, we report a new family of NZTE materials based on triple tetragonal‐tungsten‐bronze (TTB) oxides, including Ta 8 W 9 O 47 (TWO), (Nb 0.5 Ta 0.5 ) 8 W 9 O 47 (NTWO), and (Nb 0.5 Ta 0.5 ) 8 (Mo 0.5 W 0.5 ) 9 O 47 (NTMWO), synthesized via solid‐state reaction and entropy‐driven cation doping. High‐temperature X‐ray diffraction reveals anisotropic lattice behavior in all compositions: positive expansion along the a ‐ and b ‐axes counterbalanced by negative expansion along the c ‐axis. This compensation yields average linear coefficients of thermal expansion (CTE) near zero ( α l < 1.30 µK −1 ) from 300 to 1673 K. Notably, Nb‐doping in NTWO optimizes this balance, achieving the lowest α l of 0.656(43) µK −1 . Distinct temperature regimes highlight specific advantages: TWO maintains stable NZTE ( α dil = −0.455(1) µK −1 ) from 173–773 K; NTWO exhibits ultralow CTE (−0.079(1) µK −1 ) between 473–773 K; and NTMWO demonstrates exceptional dimensional stability at cryogenic temperatures (93–300 K, α dil = −0.096(1) µK −1 ). The bulk NZTE behavior stems from the synergy between the intrinsic anisotropic lattice expansion and microstructural features, such as rod‐like grains and porosity. These results establish Ta 8 W 9 O 47 ‐type TTB oxides as a robust, non‐ferroelectric platform for designing single‐phase NZTE ceramics for precision and aerospace applications.

ABSTRACT Metal anode batteries, particularly divalent systems including magnesium (Mg) and calcium (Ca), are promising candidates for next‐generation energy storage due to their high natural abundance and superior theoretical energy densities. However, the electrode/electrolyte interphase remains the paramount factor limiting the reversibility and reaction kinetics of Mg and Ca metal deposition/dissolution. Unlike the ionic‐conductive interphase demonstrated in monovalent metal (Li and Na) anode systems, conventional electrolytes often form ion‐insulating layers on the surface of Mg and Ca anodes, putting a significant barrier for reversible stripping and plating. This review provides a systematic analysis of recent advancements in understanding how the passivation layers impact Mg 2+ and Ca 2+ transport and reduction, and how these interphases evolve during electrochemical cycling. We also scrutinize the chemical composition and microstructures of the interphases in relation to electrolyte formulations. By establishing a correlation among electrolyte chemistry, interphase properties, and electrochemical performance for Mg and Ca metal anodes, this work provides a roadmap for the rational design of effective interphases for viable Mg and Ca metal batteries.

ABSTRACT The advancement of intelligent self‐powered systems in rapidly evolving industries operating under challenging environments (COEs), particularly in aerospace, aviation and navigation (AAN), has created a growing demand for real‐time sensing and efficient energy conversion devices. Triboelectric Nanogenerators (TENGs) offer promising solutions and are well‐suited for COE applications. However, existing high‐level studies remain fragmented and lack systematic linkage. A comprehensive review of TENG materials, applications and integration strategies is therefore warranted to guide future research and optimize their impact. In this review, we first summarize the harsh operating conditions commonly encountered in COE applications and analyze how these conditions interfere with TENG performance. Based on this framework, we provide a detailed overview of advanced and innovative materials with tailored properties designed to withstand extreme environmental challenges. We then retrospectively examine TENG applications in energy harvesting, structural health monitoring, and human–machine interaction within AAN‐related COEs. Finally, we outline key future directions, including materials multifunctionality, enhanced human–machine compatibility, performance improvement, and integration with artificial intelligence. With the continued development of AAN technologies, TENGs are poised to play a pivotal role in advancing sustainable energy and self‐powered sensing solutions.
