Soft electronics for biomedical and wearable applications have advanced rapidly in recent years, yet their power delivery relies on rigid battery packs, limiting the development of thin-film electronic devices. In this work, we present the design and fabrication of an intrinsically stretchable thin-film organic rechargeable Na-ion battery via addressing the fundamental materials challenges, enabled by the biocompatible and eco-friendly organic Na-ion electrochemistry, rational design of a solvent-resistant stretchable current collector, a strain-adaptable gel polymer electrolyte based on a dynamic polymer framework, and composite electrodes with tunable modulus, by introducing a dual-network polymerization strategy. Collectively, these advancements yield an elastic battery cell maintaining 85% capacity at 30% strain with a Coulombic efficiency (CE) near 100%, stable cycling with 93.6% capacity retention for 130 cycles, and a high CE above 99.8% at 2C. Overall, it presents a promising platform for next-generation thin-film stretchable power sources for wearable and biomedical electronic devices.

Liquid metal (LM)-based multifunctional composites enable numerous soft electronic applications yet are typically electrically insulating as fabricated due to the native oxide layer and encapsulating polymer matrix. Mechanical sintering is widely used to activate electrical conductivity, but the underlying mechanism remains elusive. Here, we visualize and quantify mechanical sintering in liquid droplet-elastomer composites, showing that electrical activation does not arise from surface tension-driven coalescence, but from mechanically induced matrix cracking that enables network formation. Coupled electro-mechanical measurements, imaging, and quantitative analysis in LM and glycerol systems reveal that stress-induced cracks open transient fluid pathways between droplets, allowing localized coalescence to develop into persistent, globally percolated conductive networks. A fracture-based framework predicts percolation across droplet sizes from millimeters to tens of micrometers and architectures from paired droplets to homogeneous and heterogeneous bulk composites. These findings establish a fracture-mediated electrical activation mechanism and provide design and manufacturing principles for mechanically activated soft electronics.

Per- and polyfluoroalkyl substances (PFAS), or “forever chemicals,” are emerging environmental contaminants with adverse human health effects. PFAS usage stems from their inherent chemical inertness. Inspired by the native structure of plant suberin, we design the fluorine-free superhydrophobic lignin-integrated particle (SLIP) coating as a biodegradable alternative to PFAS use in superhydrophobic applications. SLIP coatings achieve pH stability, superhydrophobicity, ultraviolet stability, anti-fouling behavior, and biodegradability due to linking a chemically inert lignin backbone with long-chain alkyl groups to minimize surface energy. Structure analysis reveals that SLIP coatings mimic suberin-enriched structures found in natural wood, enlightening both in planta mechanisms and proving the bio-inspired principle for superhydrophobic design. Finally, rigorous integrated life cycle assessment and social cost analysis reveal that SLIPs simultaneously optimize functional performance, mitigate the substantial health damages of PFAS, and significantly reduce global social costs. We envisage this study to advance the development of next-generation, environmentally sustainable PFAS alternatives.

α-FAPbI3 (FA is formamidinium) is an ideal candidate for next-generation X-ray detectors; however, synthesizing stable α-FAPbI3 relies on cation or anion alloying, which introduces detrimental cation-anion segregation and thermal decomposition. Here, we present a polymer-coordinated direct-ink writing process that overcomes this challenge, enabling the first alloying-free, ambient-air synthesis of stable α-FAPbI3 thick films. Through in situ characterizations and simulations, we demonstrate that polyvinylpyrrolidone (PVP) coordinates with both FA+ and Pb2+ cations, retarding crystallization kinetics and promoting α-FAPbI3 formation. Furthermore, PVP induces lattice compression during cooling, counteracting FA+-driven lattice expansion and stabilizing α-FAPbI3 at room temperature. Single-pixel detectors fabricated from 307-μm-thick α-FAPbI3 films demonstrate an effective gain-assisted photon-to-charge output (9.47 × 10−4 nC photon−1), ultralow-dose image acquisition (4.1 nGyair), and millisecond-scale response. The 256 × 256 multipixel imager achieves real-time X-ray imaging with a spatial resolution of 5.0 lp mm−1, outperforming previous perovskite-based and many commercial X-ray imagers.

Understanding how corrosion evolves at the nanoscale is essential for designing durable materials, yet its atomistic mechanisms under non-equilibrium conditions remain poorly understood. Here, we combine in situ liquid-phase transmission electron microscopy with kinetic Monte Carlo simulations to directly visualize and quantify temperature-dependent corrosion of individual Pd nanocubes. Increasing temperature accelerates corrosion by over an order of magnitude while driving distinct transitions in corrosion pathways. We identify three regimes: (1) corner-dominated corrosion near equilibrium at 303 K, (2) strain-mediated terrace pitting under intermediate-equilibrium conditions at 318 K, and (3) rapid, spatially homogeneous corrosion far from equilibrium at 333 K. Near equilibrium, locally strained surface sites exhibit preferential corrosion, whereas far from equilibrium, the increased thermodynamic driving force overrides structural heterogeneity, resulting in rapid and uniform corrosion. These findings establish a mechanistic framework linking temperature, thermodynamic driving force, and local structural heterogeneity to corrosion dynamics, offering design principles for corrosion-resistant materials.

Mechanical cues can reshape chromatin organization, yet whether such changes at specific loci can be harnessed to activate gene expression remains unclear. Here, we show that transient nuclear deformation not only drives global remodeling of chromatin accessibility, DNA methylation, and higher-order genome architecture but also reproducibly increases accessibility at promoters of transcription factors, including Ascl1 and Oct4. By coupling CRISPR-based transcriptional activation (CRISPRa) with guide RNAs designed to target these mechanically primed regions, we achieve enhanced activation of endogenous genes and improved fibroblast-to-neuron reprogramming efficiency. In addition, mechanically informed CRISPR activation of endogenous Oct4 induces a transient partial reprogramming state that further boosts reprogramming outcomes. Together, these findings establish a mechano-epigenetic strategy for overcoming chromatin barriers and provide a general framework for improving cell fate conversion.

Conventional imaging modalities often cannot simultaneously capture high-fidelity surface geometry and internal microstructure. Here, we develop a dual-modality three-dimensional imaging framework that integrates structured-light scanning with X-ray computed tomography to establish accurate spatial correspondence between external morphology and internal features. A monolayer photonic-crystal manganese halide gel scintillator, fabricated by sacrificial-layer transfer, retains 85% optical transmittance and >20 lp mm−1 X-ray resolution while delivering ∼58% higher X-ray-induced light output than the pristine gel. Rigorous coupled-wave analysis and electric-field simulations reveal that the photonic-crystal layer efficiently out-couples scintillation photons confined by total internal reflection, thus significantly boosting light-extraction efficiency. High-resolution tomography of a seahorse specimen is registered with external point clouds through iterative boundary extraction and optimization, achieving 89.5% coverage within a 1.0 mm tolerance. This strategy enables integrated three-dimensional visualization of internal and external structures, providing a general route toward high-fidelity multimodal imaging.

Zirconium-based halide electrolytes are promising candidates for all-solid-state lithium batteries (ASSLBs) owing to their low cost and facile processability, but their practical application is constrained by insufficient ionic conductivity. Here, we develop a dual-anion strategy to induce covalency-driven amorphization in O2−/Br−-doped Li2ZrCl6. Covalent Zr-Br interactions promote charge delocalization and weaken electrostatic interactions, while Zr-O-Zr bridges disrupt long-range structural ordering, collectively enhancing lattice flexibility and lowering the Li+ migration barrier. The resulting Li2.25ZrCl4O0.75Br0.75 electrolyte achieves a room temperature ionic conductivity of 1.95 mS cm−1 together with enhanced oxidative and interfacial stability up to 4.5 V. When integrated into LiNi0.8Co0.1Mn0.1O2-based ASSLBs, the full cell delivers superior rate capability and retains 89.0% capacity after 1,000 cycles. This work establishes bond-covalency-mediated anion sublattice regulation as an effective strategy for coupling structural amorphization with fast ion transport, providing a design principle for high-performance halide solid-state electrolytes.

Global freshwater scarcity and rising energy demand call for cogeneration technologies. Here, we report a flower-inspired, shape-programmable 3D solar evaporator built from polyaniline-coated alginate/ramie yarns with an embedded dual-wire thermoelectric core. The conductive core enables a fixed 90° conical geometry that traps light through multiple internal reflections, raising the hot section to ∼62°C and generating 38 mV under 1 sun. The device achieves a dual-sided evaporation rate of 1.77 kg m−2 h−1 and stable thermoelectric response (∼17 mV). In 3.5 wt % NaCl solution, it sustains 1.54 kg m−2 h−1 with self-desalting and no surface crystallization. Even in 21 wt % brine, salt deposits only at the periphery, preserving central optical activity. Outdoor trials yield 10.41 kg m−2 day−1 of WHO-compliant freshwater and a peak thermovoltage of 17.45 mV. By combining geometry-assisted photon management, capillary regulation, and robust yarns, this device offers a promising approach toward off-grid, modular water-electricity cogeneration for coastal and island communities.
全球淡水短缺和不断增长的能源需求呼唤热电联产技术。在这里，我们报告了一种以花为灵感、形状可编程的3D太阳能蒸发器，该蒸发器由聚苯胺涂层的海藻酸盐/苎麻纱线制成，并带有嵌入式双线热电芯线。导电芯实现固定的90°锥形几何形状，通过多次内部反射捕获光，将热部分提高到~ 62°C，在一个太阳下产生38 mV。该装置实现了1.77 kg m−2 h−1的双面蒸发速率和稳定的热电响应（~ 17 mV）。在3.5 wt % NaCl溶液中，它能维持1.54 kg m−2 h−1，自脱盐且无表面结晶。即使在21%的盐水中，盐也只沉积在外围，保留了中心的光学活性。室外试验产生10.41 kg m−2 day−1符合世卫组织标准的淡水，峰值热电压为17.45 mV。通过结合几何辅助光子管理、毛细管调节和坚固的纱线，该设备为沿海和岛屿社区提供了一种有前途的离网、模块化水电热电联产方法。

Here, we report a flower-inspired, shape-programmable 3D solar evaporator built from polyaniline-coated alginate/ramie yarns with an embedded dual-wire thermoelectric core. The conductive core enables a fixed 90° conical geometry that traps light through multiple internal reflections, raising the hot section to ∼62°C and generating 38 mV under 1 sun. The device achieves a dual-sided evaporation rate of 1.77 kg m−2 h−1 and stable thermoelectric response (∼17 mV). In 3.5 wt % NaCl solution, it sustains 1.54 kg m−2 h−1 with self-desalting and no surface crystallization. Even in 21 wt % brine, salt deposits only at the periphery, preserving central optical activity. Outdoor trials yield 10.41 kg m−2 day−1 of WHO-compliant freshwater and a peak thermovoltage of 17.45 mV. By combining geometry-assisted photon management, capillary regulation, and robust yarns, this device offers a promising approach toward off-grid, modular water-electricity cogeneration for coastal and island communities.","PeriodicalId":388,"journal":{"name":"Matter","volume":"33 1","pages":""},"PeriodicalIF":18.9,"publicationDate":"2026-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149218216","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
