ABSTRACT High‐performance organic photovoltaic (OPV) materials, characterized by tunable energy levels, broad light absorption, and facile processability, show considerable potential for photocatalytic applications. However, their inherent susceptibility to oxygen and moisture limits their practical use under complex reaction conditions. Here, organic photocatalyst/adsorbent systems based on dono…

ABSTRACT Oscillatory fluid flows underpin transport, mixing, and signal propagation in living systems, yet artificial microfluidic platforms rely almost extensively on external power or chemically driven gradients to reproduce such dynamics. Here, we introduce a fuel‐free strategy based on photo‐mechanical transduction, in which light is directly converted into mechanical deformation of soft matt…

ABSTRACT Metal–organic frameworks (MOFs) and porous coordination polymers (CPs) are promising electrocatalysts for CO 2 reduction, but suffer from poor stability and mass transfer limitations at high current densities. While nonporous CPs show efficient CO 2 ‐to‐C 1 conversion with exceptional stability, their application for C 2 synthesis remains unexplored. Herein, we report the first rational …

ABSTRACT The development of high‐efficiency counter electrodes (CEs) is a pivotal challenge for advancing the performance of quantum dot‐sensitized solar cells (QDSSCs). This study reports the rational synthesis of a CuS/C‐DCN ox heterostructure, featuring copper sulfide nanoparticles (CuS) anchored onto a nitrogen‐vacancy‐rich, mildly oxidized defective carbon nitride matrix (DCN ox ). The contr…

ABSTRACT Carbon quantum dots (CQD) constitute a unique class of materials for biomedical applications due to their inherent optical properties and biocompatibility. However, currently, there is no generalized universal procedure for conjugation of CQD with biopolymers, which significantly reduces their practical value. Here we show an ultrafast “salting out on a surface” (SOS) method for the conj…

ABSTRACT The accurate measurement of ionic displacements in ferroelectrics by transmission electron microscopy (TEM) requires the illumination to be aligned exactly along a low‐index crystal zone axis. Adjacent domains in ferroelastic materials are often inherently inclined, hindering trustworthy structural imaging across domain boundaries at present. In this work, we overcome this limitation by …

ABSTRACT Artificial muscles represent compliant soft actuators capable of replicating biomimetic contraction, which fill the performance gap between rigid electromechanical equipment and biological tissues. This review systematically consolidates cutting‐edge progress across four core dimensions: functional material systems, bioinspired structural architectures, multi‐field actuation mechanisms, …

ABSTRACT Potassium metal batteries (PMBs) are promising candidates for next‐generation large‐scale energy storage owing to their high energy density and cost‐effectiveness. However, their rate capability and cycling stability are severely hindered by sluggish K + transport kinetics, uncontrolled dendrite growth, and fragile solid electrolyte interphase (SEI) at the K anode. Herein, a hierarchical…

ABSTRACT Mastering phase transitions of molecular materials is essential for regulating their optical functionalities, yet realizing glass materials that integrate multidimensional optical properties still poses a major challenge. Herein, we report a molecular π‐extension strategy to modulate phase evolution for constructing all‐in‐one polar hybrid glass‐ceramics featuring integrated multidimensi…

ABSTRACT Ammonium perchlorate (AP), the pivotal oxidizer in composite solid propellants, is often constrained due to its high decomposition temperature and sluggish heat release. Here, we proposed a structural co‐assembly strategy which synergistically assembles energetic moieties and reduction units. Through this approach, two 2D energetic metal–organic frameworks (EMOFs), {Zn 2 (datz) 2 (CBH) 2…

ABSTRACT Conventional photocatalysts pronounced electron‐hole recombination and a limited number of active sites. To address these challenges, Bi‐N bridged bonds were interlinked at the interface of the heterojunction via coating crystalline Bi 2 MoO 6 with amorphous MOF (Bi 2 MoO 6 @ZIF‐Fe). Simultaneously, Bi metal vacancies (V M ) and MoO 3 quantum dots (QDs) were formed to accelerate the tran…

ABSTRACT Ever since the discovery of graphene via mechanical exfoliation of graphite, 2D nanomaterials have garnered wide interest for high‐performance electronics. Mechanical exfoliation of van der Waals (vdW) layered materials produces nearly perfect 2D nanomaterials, yet their application in electronics is impeded by the low yield and random orientation of the resulting flakes. In this work, w…

ABSTRACT Aqueous two‐electron Zn–I 2 (I ‒ /I 0 /I + ) batteries offer high theoretical energy density; however, their practical operation is limited by hydrolysis of iodine monochloride (ICl), which induces cathode irreversibility and Zn‐anode degradation. Here, we introduce an ether‐based complexation strategy that stabilizes interhalogen species and mitigates cross‐talk degradation in aqueous t…

ABSTRACT Mimicking the adaptive light‐energy management of natural photosynthetic systems remains challenging, particularly in aqueous media where efficient multistep energy transfer and environmental responsiveness are rarely integrated within a single nanoscale architecture.

ABSTRACT The anode‐cathode crosstalk, driven by bilateral OH − and polyhalide shuttling, forms an underestimated vicious cycle that critically degrades the capacity of aqueous Zn halogen batteries (AZHBs). In this cycle, anode corrosion produces OH − , whose migration exacerbates cathode decay and polyhalide shuttling, which in turn leads to corrosion and increased OH − production at the anode. T…

ABSTRACT Aqueous Zn–I 2 batteries combine safety, sustainability, and high theoretical capacity, making them a promising energy storage solution. However, their practical employment is impeded by challenges such as uncontrolled dendrite growth on the Zn anode, severe polyiodide shuttling effect, and the dissolution of the I 2 cathode. Herein, we propose di‐ tert ‐butyl(3‐sulfonatopropyl) phosphin…

ABSTRACT Natural load‐bearing tissues derive mechanical performance from sequential self‐assembly, in which collagen fibrils first compact and are then stabilized by enzymatic covalent crosslinking.
