Inspired by the extracellular matrix (ECM), which integrates a fibrous collagen scaffold with a hydrated polysaccharide matrix, we developed a PVDF-based ternary dielectric energy storage film by introducing hydroxypropyl-β-cyclodextrin (HP-β-CD) within a fluorinated methacrylate crosslinked network. The crosslinked network serves as a compact insulating scaffold analogous to collagen fibers, while HP-β-CD mimics the hydrated polysaccharide components. The abundant hydroxyl groups of HP-β-CD form stable hydrogen bonds with PVDF chains, strengthening interfacial adhesion and tuning local chain conformation. Under an external electric field, the polar hydroxyl and hydroxypropyl groups of HP-β-CD contribute to orientational polarization, increasing the dielectric constant to 9.7. In addition, the hydroxyl-rich exterior and cavity-bearing structure of HP-β-CD may provide charge-trapping sites that help suppress charge accumulation and conduction losses, thereby retarding electrical breakdown. The fluorinated crosslinked network enhances breakdown strength by restricting PVDF segmental motion and improving film compactness and structural stability. Consequently, the leakage current density decreases to 5.25 × 10 –7 A/cm 2 , approximately one order of magnitude lower than that of neat PVDF (2.02 × 10 –6 A/cm 2 ). Benefiting from this ECM-inspired molecular-regulation approach, the optimized composite achieves a discharged energy density of 9.03 J/cm 3 at 560 MV/m, while the residual PVDF-related hysteresis indicates that further efficiency optimization remains necessary for practical high-efficiency capacitor applications.

Broadband microwave absorbing (MA) materials that are lightweight and thin are highly desirable for advanced electromagnetic protection applications. Multilayer absorber architectures offer an effective route to broaden absorption bandwidth via stepwise impedance matching, yet film fabrication processes for incorporating powder absorbers often suffer from limited scalability and thickness controllability. Herein, we report a solvent-free dry-process strategy to fabricate MA films. Polyimide (PI) is employed as the dielectric matrix, carbon nanotubes (CNTs) as the lossy phase, and polytetrafluoroethylene (PTFE) as the binder, which forms a continuous 3D microfibrillar network under mechanical shear. This dry-processed approach affords uniform filler dispersion, precise thickness control, and high mechanical integrity without solvent-induced phase separation. Benefiting from the well-defined thickness and modularity of the dry-processed films, multilayer absorbers are fabricated via alternating stacking of the films with low-density dielectric foam layers. The resulting structure delivers an effective absorption bandwidth of 12.45 GHz at a total thickness of about 6 mm, spanning the X-Ku frequency range. This work demonstrates that dry-processed film fabrication coupled with multilayer impedance engineering offers a scalable preparation pathway toward broadband, lightweight, and customizable microwave absorbers.

Industrial solid wastes, such as fly ash and slag, are generated at an enormous scale but remain insufficiently valorized. This work develops a geopolymer-polyacrylamide (Geo-PAAm) structural electrolyte from these wastes through a viscoelastic-controlled pore-engineering strategy. The resulting electrolyte contains interconnected hierarchical micropores and macropores that improve pore connectivity and provide efficient Zn 2+ transport pathways. As a result, Geo-PAAm delivers high ionic conductivity, stable Zn plating/stripping, and long-cycle performance in zinc-ion full cells. More importantly, its high compressive strength enables brick batteries that continue operating under severe mechanical and thermal abuse, including puncture, burning, and vehicular compression. This study demonstrates a route to convert low-value industrial waste into load-bearing energy-storage materials, offering a scalable platform for sustainable, energy-storage-integrated buildings.

Host-gut microbiota metabolic interactions are implicated in the pathogenesis of ulcerative colitis (UC), but the underlying mechanisms of certain metabolites remain ambiguous. Here, we revealed an impaired bile acid homeostasis in UC with a significant deficiency of hyodeoxycholic acid (HDCA), which was inversely correlated with the severity of UC. Ruminococcus callidus was linked to altered HDCA generation, and colonization of R. callidus increased HDCA concentrations via bile salt hydrolase. Single-cell RNA sequencing (ScRNA-seq) indicated that HDCA reshaped the intestinal macrophage landscape by enriching a metabolically rewired Mrc1 + macrophage subpopulation with immunosuppressive features. Mechanistically, HDCA enhanced PPARγ-mediated fatty acid metabolism reprogramming to alleviate inflammation, which was blunted in myeloid PPARγ-deficient mice. HDCA triggered fatty acid oxidation to promote ATP citrate lyase-dependent histone acetylation, supporting epigenetics-mediated gene regulation and the phenotypic modification of macrophages. These findings uncover a unique mechanism of gut microbiota-derived HDCA regulating metabolism, providing therapeutic potential for UC.

Biomimetic rigid-skeleton/viscous-channel architecture; • Minority HEMA regulates phase separation without backbone compromise; • Wide tensile strength (0.26–5.5 MPa) & high fracture energy (5.2 kJ m −2 ); • Excellent damping with peak tanδ of 1.25; • Motion-artifact-resistant bioelectrodes for reliable ECG/EMG monitoring. Motion-induced artifacts arising from insufficient energy dissipation severely hinder the practical application of eutectic gels in bioelectronics. Feline paw pads possess remarkable damping capability, enabling quiet locomotion through a multiphase architecture that synergistically combines load-bearing collagen frameworks with energy-dissipating adipose compartments. Inspired by this biological design, we report a biomimetic damping eutectic gel synthesized via a comonomer-mediated phase separation regulation strategy. By introducing a fraction of 2-hydroxyethyl methacrylate into an acrylic acid/deep eutectic solvent system, the phase morphology can be finely regulated without compromising the primary load-bearing network. This structural decoupling gives rise to a rigid-skeleton/viscous-channel architecture, endowing the gel with widely tunable tensile strength from 0.26 to 5.5 MPa, high fracture energy of 5.2 kJ m −2 , and extraordinary damping capacity. When used as epidermal bioelectrodes, the gels exploit their intrinsic damping capability to effectively suppress motion artifacts, enabling continuous, high-fidelity physiological signal monitoring.

Development of a droplet-driven self-powered electronic skin for robotic hand disinfection. • Integration of energy harvesting, antibacterial activity, and tactile sensing within a flexible platform. • Synergistic ROS generation and localized electric-field enhancement enable rapid bacterial inactivation. • Achieves >99.999% inactivation of E. coli and S. aureus without external power input. • Provides a multifunctional strategy for biosafe robotics and intelligent human–machine interfaces. Surface contamination on robotic hands and electronic skin poses a growing biosafety concern in medical care, laboratory operation, food processing, and human-machine interaction. Conventional disinfection strategies, such as chemical disinfectants, ultraviolet irradiation, and antibacterial coatings, often require external energy input, cause chemical residues, or show limited compatibility with flexible robotic surfaces. Therefore, developing a self-powered, on-demand, and in situ disinfection strategy for robotic electronic skin is highly desirable. Here, a droplet-driven self-powered antibacterial electronic skin based on an Al-FEP-PPyNW-PM (an Al needle electrode-integrated superhydrophobic FEP-PPy nanowire-PDMS@MXene multilayer film) is proposed. Water droplets naturally impact the multilayer film, converting droplet kinetic energy into electricity and triggering antibacterial reactions on robotic hands. The superhydrophobic FEP layer promotes rapid droplet contact–separation and enhances interfacial charge generation. The Al needle electrode supports charge collection and electron transfer. The PDMS@MXene substrate provides a flexible conductive network and piezoresistive sensing capability. The PPy nanowire tips amplify the localized electric field near bacteria. Droplet-induced electron transfer activates dissolved oxygen and produces reactive antibacterial species, including hydrogen peroxide, hydroxyl radicals, and superoxide radicals. These species synergize with localized electric-field-induced membrane disruption to achieve rapid bacterial inactivation. The system exhibits stable electrical output under repeated droplet impact and shows efficient antibacterial performance against both Gram-negative and Gram-positive bacteria. Meanwhile, the PDMS@MXene@PPy composite demonstrates reliable piezoresistive sensing, enabling the film to function as an integrated electronic skin. Overall, this work integrates droplet energy harvesting, ROS-mediated disinfection, localized electric-field enhancement, and pressure sensing into a multifunctional robotic interface, offering a promising strategy for self-disinfecting robotic hands without external power or chemical disinfectants.

Bottlebrush copolymers exhibit enhanced conformational stability and have potential for antibacterial and antifouling materials. In this work, cationic bottlebrush copolymers composed of poly(ethylene glycol) methyl ether methacrylate (PEGMA) and quaternized 2-(dimethylamino)ethyl methacrylate (QDMAEMA) were synthesized via controllable atom transfer radical polymerization. The as-prepared bottlebrush copolymers were subsequently blended with polyethersulfone to fabricate robust membranes with combined antibacterial and antifouling properties. Compared to their linear analogues, the bottlebrush copolymer-based membranes exhibited enhanced antibacterial efficacy against Escherichia coli and Staphylococcus aureus , along with faster bactericidal kinetics. This improvement is attributed to the increased surface exposure of quaternary ammonium groups in the bottlebrush architectures, which strengthen electrostatic interactions with negatively charged bacteria. Additionally, the densely packed side-chain arrangement stabilized hydration layers, thereby suppressing protein adsorption and bacterial adhesion. Notably, the optimized bottlebrush copolymer-based membranes exhibited excellent durability, retaining over 99% antibacterial activity after five cycles. Hemolysis and cytotoxicity assays confirmed that the bottlebrush copolymer-based membranes were biocompatible with mammalian cells. Our results highlight a topology-based strategy for fabricating functional materials with synergistic antibacterial and antifouling capabilities.

All-inorganic phosphor composites have emerged as vital solutions for high-power solid-state lighting, circumventing the intrinsic thermo-chemical vulnerabilities and spectral instabilities of conventional polymer-encapsulated matrices. Here, we report self-supporting, ultrathin phosphor-glass composites (PGC) utilizing commercial Ca-α-sialon:Eu 2+ amber phosphors as the luminescent component. Leveraging tape-casting and low-temperature sintering, we achieve microscale control over composite thickness (117 µm) and phosphor distribution, while maintaining crystalline integrity and delivering a high internal quantum yield of 95.59%. Systematic tuning of phosphor loading reveals that photon transport—governed by multiple scattering and self-absorption—is the dominant limiter of apparent emission in the ultrathin regime, with an optimal loading identified at 20 wt.%. Furthermore, we engineer a dual-layer laminated architecture that spatially decouples light conversion from mechanical reinforcement and thermal buffering. This configuration effectively suppresses chromatic drift and improves luminous stability and efficiency retention under high-power excitation. Notably, the laminated PGC exhibit superior tensile strength, moisture resistance, and thermal dissipation without compromising luminescence performance. These results establish architecture-enabled ultrathin PGC as a promising photonic packaging platform for next-generation color-stable, high-power solid-state lighting.

An inverted conical micro-array is developed via template-assisted strategy to enhance sensing reliability. • Geometrical confinement of recessed structures effectively shields the sensing interface from shear interference. • The sensor achieves a high SNR of 48.43 dB and high-fidelity capture of subtle physiological features. High sensitivity and a broad linear range are often mutually exclusive in resistive pressure sensors. This work reports a geometrical confinement strategy to resolve this trade-off by developing a CNT/graphene-TPU composite sensor featuring an inverted conical micro-array. Unlike conventional convex or planar architectures, the recessed geometry introduces a controlled inward-deformation mechanism, which significantly enhances localized stress concentration and optimizes the regulation of conductive pathways. Crucially, this inverted structure acts as a mechanical shield that suppresses friction-induced micro-slippage and contact-area fluctuations, effectively isolating the sensing interface from external shear perturbations. Consequently, the sensor achieves an exceptional signal-to-noise ratio (SNR) of 48.43 dB, a high sensitivity of 293 kPa −1 , in the low-pressure range of 0–12 kPa, and a wide linear sensing range. The device’s superior signal fidelity is demonstrated through high-precision physiological monitoring and tactile mapping, where it captures subtle pulse features (e.g., diastolic waves) typically masked by noise. This study provides a novel perspective on leveraging recessed micro-architectures to achieve high-performance, interference-immune wearable electronics.

Magnéli phase Ti 6 O 11 ceramics were prepared by the solid-state reduction of TiO 2 with graphite. By adding zinc oxide during processing, dual energy-filtering systems comprising defect clusters and carbon layers were formed in the ceramics. The power factor showed a significant increase with the addition of zinc oxide during preparation. At 973 K, the sample with x = 0.03 exhibited a power factor of 380 μWm −1 K −2 , representing a 15% enhancement compared to the sample prepared without it. When sintered at 1400°C, the ceramic sample underwent gradual zinc volatilization, promoting the formation of defect cluster structures and carbon layers that filtered out low-energy electrons and consequently increased the absolute value of the Seebeck coefficient. Additionally, the zinc oxide acted as a fluxing agent, increasing the ceramic density by 4.5%, and the carrier mobility at 323 K was improved by 16%. The synergistic effect of the dual energy filtering mechanism and densification played important roles in the overall optimization of electrical transport performance in the materials. Finally, at 973 K, the sample with x = 0.03 achieved a thermoelectric figure of merit of 0.14, which was 12% higher than that of the sample without added zinc oxide.

Lithium‑sulfur batteries (LSBs) suffer from the “shuttle effect” and slow redox kinetics. Although MXenes serve as competitive catalytic platforms owing to their metallic conductivity, their pristine crystalline surfaces suffer from a severe spatial-electronic dichotomy. Geometrically, rigid lattice symmetries restrict the exposed catalytic active centers exclusively to edge sites, leaving the vast basal planes catalytically dormant. Electronically, the dense coverage of highly electronegative terminal groups establishes a localized negative surface potential, inducing severe electrostatic repulsion against electron-rich polar polysulfide anions. To conquer this constraint, we present a surface engineering paradigm to construct a surface-amorphized Mo 2 CT x /a-MoO x Mott-Schottky heterojunction via an in-situ oxidative strategy. This architecture triggers interfacial electronic reconfiguration, driving spontaneous electron migration from the semiconducting a-MoO x overlayer into the metallic Mo 2 CT x core to achieve thermodynamic Fermi level equilibration. The resulting built-in electric field establishes a localized electron-deficient capture layer on the surface, successfully neutralizing the native electronegative electrostatic repulsion barrier of the MXene framework. Synchronously, the amorphous a-MoO x shell disrupts crystalline steric hindrances, awakening a massive density of unsaturated Mo 5+ defect states that initiate a Mo S and Li O dual-anchoring chemisorption mode. Benefiting from this spatial-electronic liberation, the modified separator lowers the thermodynamic activation barriers for bidirectional sulfur conversion. Li S cells integrated with the Mo 2 CT x /a-MoO x -modified separator deliver a high initial specific capacity of 1309.4 mAh g −1 at 0.2C, high-rate capability up to 4C (597.2 mAh g −1 ), and robust cycling stability under a sulfur loading of 6.43 mg cm −2 (747.3 mAh g −1 maintained after 70 cycles). This work establishes a fundamental paradigm for leveraging localized surface amorphization and Mott-Schottky charge dynamics to manipulate surface potentials and conquer interfacial repulsion in advanced energy storage applications.

A photocatalytic self-propelled nanomotor adsorbent was developed for Pd(II) recovery. • Self-propulsion overcomes diffusion-limited adsorption kinetics. • EPR reveals the ROS-mediated mechanism of long-term propulsion. • Selective Pd(II) recovery is achieved in complex acidic wastewater. The recovery of palladium (Pd) from complex acidic industrial wastewater is severely restricted by sluggish interfacial mass transfer and inherent diffusion-limited adsorption kinetics. To address this long-standing bottleneck, asymmetric N/Se-codoped resorcinol-formaldehyde nanomotors (Se-RF@NMs) were rationally fabricated via an emulsion-confined anisotropic growth strategy for photocatalytic self-propulsion-boosted Pd(II) recovey. Under light irradiation, the photoresponsive resin framework enables continuous in-situ H 2 O 2 generation. Meanwhile, the adsorption-induced in-situ reduction of Pd(II) further accelerates catalytic H 2 O 2 decomposition to generate oxygen microbubbles, endowing nanomotors with sustainable autonomous motion and dynamically promoting interfacial ion transport. EPR characterization confirms that photogenerated holes and reactive oxygen species sustain the cyclic H 2 O 2 generation-decomposition system, effectively stabilizing the self-propulsion behavior of Se-RF@NMs. Benefiting from the synergistic coupling of photocatalytic self-propulsion and N/Se-based selective coordination adsorption, the optimized Se-RF@NMs achieve a superior Pd(II) adsorption capacity of 196.75 mg g −1 , as well as excellent selectivity in multi-metal competitive systems and practical industrial wastewater matrices. This work elucidates a photocatalysis-driven active mass transfer enhancement mechanism, establishing a feasible paradigm to break the intrinsic diffusion limitation of conventional adsorption. It provides new insights into the rational design of intelligent self-propelled catalytic adsorbents for high-efficiency precious metal recovery in complex and harsh water environments.
