As an emerging thermal management strategy, dynamic radiative cooling (DRC) technology enables dynamic modulation of spectral radiation properties under varying environmental conditions through the directional design of material spectral characteristics. However, a comprehensive review of the basic physical mechanisms of radiative heat transfer in DRC materials and various design principles involved in dynamic radiative thermal regulation is still lacking. This review systematically summarizes recent advances in this field, spanning from fundamental physical principles to intrinsic molecular and electronic mechanisms, and further to representative material systems and multi-band regulation strategies, highlighting the interdisciplinary research achievements and technological innovations. This work outlines the core mechanisms governing the regulation of different spectral bands during radiative heat transfer processes. Then, the main categories of DRC materials are systematically reviewed, including actively responsive structures, passively responsive structures, and multi-stimuli-responsive materials. Furthermore, the challenges faced by current DRC technology and future development trends are summarized and discussed, providing valuable reference and guidance for further research in this field. Although DRC technologies still face significant challenges in material stability, manufacturing processes, and system integration, the continuous advances in related areas and multifunctional materials are expected to broaden the application prospects of DRC in the future.

The development of gradient lubrication materials is critical for numerous biomedical applications, particularly in magnifying mechanical properties and service longevity. Herein, we present an innovative approach to fabricate biomimetic gradient lubrication hydrogel through the synergistic integration of three-dimensional (3D) printed metal-organic frameworks (MOFs) nanoparticle network hydrogel skeletons with bio-inspired lubrication design. Specifically, robust hydrogel skeletons were engineered through single or multi-material 3D printing, followed by the in situ growth of MOFs nanoparticles within this hydrogel network to create a reinforced, load-bearing architecture. Subsequently, biomimetic lubrication capability was enabled by mechanically coupling another lubricating hydrogel within 3D-printed MOFs nanoparticle network hydrogel skeleton. The superficial layer is highly lubricious to ensure low coefficient of friction (~ 0.1141) and wear resistance (40,000 cycles), while the deeper layer is stiffer to afford the obligatory mechanical support (fracture strength ~ 2.50 MPa). Furthermore, the gradient architecture stiffness of the hydrogel can be modulated by manipulating the spatial distribution of MOFs within the 3D-printed hydrogel skeleton. As a proof-of-concept, biomimetic gradient hydrogel meniscus structures with C- and O-shaped configurations were constructed by leveraging multi-material 3D printing, demonstrating exceptional lubrication performance. This innovative biomimetic design opens new avenues for creating implantable biomedical gradient lubricating materials with reinforced mechanical and lubrication performance.

The lack of macro-continuity and mechanical strength of covalent organic frameworks (COFs) has significantly limited their practical applications. Here, we propose an "alcohol-triggered defect cleavage" strategy to precisely regulate the growth and stacking of COF grains through a moderate reversed Schiff base reaction, realizing the direct synthesis of COF nanofibers (CNFs) with high aspect ratio (L/D = 103.05) and long length (> 20 μm). An individual CNF exhibits a biomimetic scale-like architecture, achieving superior flexibility and fatigue resistance under dynamic bending via a multiscale stress dissipation mechanism. Taking advantages of these structural features, we engineer CNF aerogels (CNF-As) with programmable porous structures (e.g., honeycomb, lamellar, isotropic) via directional ice-template methodology. CNF-As demonstrate 100% COF content, high specific surface area (396.15 m2 g-1) and superelasticity (~ 0% elastic deformation after 500 compression cycles at 50% strain), outperforming most COF-based counterparts. Compared with the conventional COF aerogels, the unique structural features of CNF-A enable it to perform outstandingly in uranium extraction, with an 11.72-fold increment in adsorption capacity (920.12 mg g-1) and adsorption rate (89.9%), and a 2.48-fold improvement in selectivity (U/V = 2.31). This study provides a direct strategy for the development of next-generation COF materials with outstanding functionality and structural robustness.

Electrolytic Zn-MnO2 batteries are promising candidates for safe and sustainable energy storage owing to their high voltage, environmental benignity, and cost-effectiveness. However, practical applications are hindered by the poor conductivity and the irreversible dissolution of conventional ε-MnO2 deposits. Herein, we report a scalable semisolid slurry electrode architecture that enables stable MnO2 deposition/dissolution using a three-dimensional percolating network of carbon nanotubes (CNTs) as both conductive matrix and deposition host. The slurry system promotes the formation of highly conductive γ-MnO2 owing to enhanced charge transfer kinetics, enabling overall dissolution rather than the localized separation typically seen in traditional electrodes. The Zn-MnO2 slurry cell exhibits a reversible areal capacity approaching 60 mAh cm-2. Moreover, the flowable nature of the slurry allows electrochemically inactive MnO2 formed during dissolution to be reconnected and reactivated by CNTs in the rheological network, ensuring deep utilization and cycling stability. This work establishes a slurry electrode strategy to improve electrolytic MnO2 reactions and offers a viable pathway toward renewable aqueous batteries for grid-scale applications.

Organic-inorganic metal halides (OIMHs) have emerged as highly promising novel multifunctional optoelectronic materials, owing to their easily adjustable properties from a variety of combinations of different components. But it is still difficult and rare to realize highly tunable multicolor luminescence within the same material. In this work, we successfully incorporated three adjustable emission centers in OIMHs to synthesize a novel OIMH (NEA)2MnBr4, with each emission center capable of emitting one of the primary colors-red, green, and blue. The green and red emissions originate from the tetrahedron and octahedron structures in the Mn-based frame, while the blue can be attributed to the contribution of organic components. Additionally, to achieve comparable emission intensity among the three primary colors, we enhanced the blue emission performance by optimizing the ratio of organic structure components and incorporating chirality in the OIMHs. The resulting high-quality films can be obtained by spin-coating method with a photoluminescence quantum yields of up to 96%. More interestingly, by the dual manipulation of excitation wavelength and temperature, the sample can be emitted at least seven distinct colors including a standard white luminescence at (0.33, 0.33), opening up promising prospects for multicolor luminescence applications such as high-end anti-counterfeiting technology, light-emitting diodes, X-ray imaging, latent fingerprints, humidity detection, and so on. Therefore, based on application scenarios and requirements, our research on this highly tunable luminescent OIMH material lays a solid foundation for further development of various functional properties of related materials.

Conventional treatments for non-small cell lung cancer (NSCLC) suffer from low remission rates, high drug resistance, and severe adverse effects. To leverage the therapeutic potential of reactive oxygen species (ROS), nanocatalytic medicine utilizes nanomaterials to generate ROS specifically within tumor sites, enabling efficient and targeted cancer treatment. In this study, hyaluronic acid (HA)-modified copper-N,N-dimethyl-N-phenylsulfonylbisamine (DMSA)-assembled nanoparticles (Cu-DMSA-HA NPs) are developed with tumor-targeting capability and efficiently catalyze ROS production via coordination chemistry. Targeted delivery is facilitated by HA surface modification through recognition of overexpressed cluster of differentiation 44 receptors on cancer cells, which enhances nanoparticle uptake. Once internalized, intracellular glutathione is depleted by the NPs, followed by a Fenton-like reaction that sustains ROS production. Both in vitro and in vivo studies demonstrate that this catalytic strategy effectively inhibits DNA replication, prevents cell cycle progression, downregulates glutathione peroxidase 4 expression, induces ferroptosis, and ultimately suppresses NSCLC progression. Overall, the readily prepared Cu-DMSA-HA NPs exhibit robust catalytic activity and tumor specificity, highlighting their strong potential for clinical translation in nanocatalytic cancer therapy.

The development of highly efficient and multifunctional nanozymes holds promise for addressing the challenges posed by drug-resistant bacteria. Here, copper single-atom-loaded MoS 2 nanozymes (Cu SAs/MoS 2 ) were developed to effectively combat drug-resistant bacteria by synergistically integrating the triple strategies of oxidative damage, cuproptosis-like death and disruption of cell wall synthesis. Density functional theory revealed that each Cu center coordinated with three sulfur ligands, enhancing the adsorption of H 2 O 2 , which reduced the activation energy of the key step by 17%, thereby improving peroxidase-like (POD-like) activity. The generation of reactive oxygen species in combination with Cu SAs/MoS 2 glutathione peroxidase-like (GSH-Px-like) for glutathione scavenging resulted in an imbalance in redox homeostasis within bacteria. Cu SAs/MoS 2 , which act as nanopioneers, drive oxidative stress to initiate the process of cuproptosis-like death, leading to abnormal aggregation of lipoylated proteins and inactivation of iron‒sulfur cluster proteins. Moreover, Cu SAs/MoS 2 inhibited the biosynthesis of the peptidoglycan synthesis precursors d -glutamate and m-diaminopimelic acid and disrupted the peptidoglycan cross-linking process mediated by penicillin-binding proteins, effectively blocking the compensatory cell wall remodeling pathway of β-lactam-resistant bacteria. Overall, Cu SAs/MoS 2 with multiple functions can not only efficiently kill bacteria but also decelerate the development of bacterial resistance to combat drug-resistant bacterial infections.

Flexible and wearable sensors offer immense potential for rehabilitation medicine, but most rely solely on electrical signals, lacking real-time visual feedback and limiting trainee’s interactivity. Inspired by the structural coloration of Cyanocitta stelleri feathers, we developed a dual-mode sensor by utilizing black conductive polymer hydrogel (CPH)-enhanced structural color strategy. This sensor integrates a hydroxypropyl cellulose (HPC)-based structural color interface with a designed CPH sensing component. Highly visible light-absorbing CPH (absorption rate > 88%) serves as the critical substrate for enhancing structural color performance. By absorbing incoherent scattered light and suppressing background interference, it significantly enhances the saturation of structural color, thereby achieving a high contrast index of 4.92. Unlike the faint and hardly visible structural colors on non-black substrates, the HPC on CPH displays vivid, highly perceptible colors and desirable mechanochromic behavior. Moreover, the CPH acts as a flexible sensing element, fortified by hydrogen and coordination bond networks, and exhibits exceptional electromechanical properties, including 867.1 kPa tensile strength, strain sensitivity (gauge factor of 4.24), and outstanding durability (over 4400 cycles). Compared to traditional single-mode sensors, the integrated sensor provides real-time visual and digital dual feedback, enhancing the accuracy and interactivity of rehabilitation assessments. This technology holds promise for advancing next-generation rehabilitation medicine.
