Abstract Palladium-mediated bioorthogonal catalysis enables in situ activation of therapeutic and diagnostic agents within living systems, yet developing high-efficacy catalysts remains challenging. Herein, we report a wrinkled Pd metallene catalyst (Pd ML) in which nanoscale wrinkling generates abundant active sites and induces lattice strain, thereby optimizing the electronic and geometric configurations of the catalytic centers for high-performance bioorthogonal catalysis. The Pd MLs exhibit substantially enhanced catalytic activity compared to Pd nanoparticles and their wrinkle-free counterpart, flat Pd metallene. Theoretical calculations reveal that the wrinkle-induced lattice strain shifts the d-band center of Pd downward, thereby facilitating the bioorthogonal reaction. Following functionalization with the AS1411 aptamer, the Pd MLs enable targeted activation of an antitumor prodrug and realize efficient tumor suppression both in vitro and in vivo. This work represents the first example of enhancing bioorthogonal catalysis via synergistic geometric and electronic engineering, establishing a rational paradigm for the development of high-performance bioorthogonal catalysts.

Abstract Polarization-sensitive visual adaptation, the biological capability to autonomously adjust to dynamic polarized light stimuli, is a highly desirable feature for next-generation intelligent vision systems. Integrating polarized light detection and adaptive processing into a single hardware device effectively overcomes the traditional bottlenecks of artificial vision, namely, the reliance on bulky optical components and the latency caused by separated sensing and computing. Here, we report a bioinspired, self-powered, polarization-adaptive visual system based on a PbS quantum-dots (QDs)/oriented ReSe2 heterojunction. Interfacial charge trapping enables adaptive behavior, while oriented etching enhances polarization-dependent photocurrent anisotropy. Under 980 nm illumination in self-powered mode, the device achieves a photocurrent anisotropy ratio of ∼8. It further demonstrates autonomous polarization adjustment, broadband spectral responsivity, and polarization-synergistic functionalities. This work establishes a compact hardware platform for multidimensional perception and adaptive processing in intelligent vision systems.

Abstract Precise phase engineering at the atomic scale is central to advanced catalyst design, yet controlling high-temperature phase transitions remains challenging because of large kinetic barriers. Here, we report a gas-pressure-induced strategy that establishes gas pressure as an independent dimension for nanoscale phase engineering. Mechanistic studies reveal that modulating the gas-phase diffusion coefficient via the gas pressure can control the structural evolution of crystal phases. As a demonstration of this methodology, an optimal pressure effectively overcomes high-temperature constraints and retards the escape of volatile species, enabling the precise construction of phase-pure ordered PdZn intermetallics. This strategy extends to ternary PdZnCu ordered alloys, inducing significant compressive strain while preserving the long-range ordered lattice. The resulting catalyst delivers a high oxygen reduction mass activity of 1.09 A mgPd–1 and long-term durability over 30 000 cycles. This gas-pressure-induced approach circumvents conventional thermodynamic and kinetic constraints, providing a pathway for the design of advanced intermetallic catalysts.

Abstract Multielectron-conversion type and economically friendly iron fluorides are labeled as potential cathode candidates over single electron-redox intercalation oxides for Li-driven batteries. Herein, we propose a molten-perfusion-fluorination strategy to introduce pyrochlore-phase iron hydroxy fluoride into nature graphite layers. The macroscopic coralloid-like morphology, sandwich-packing with Fe–C chemical bonds, and 3D open framework endow FeF3 with abundant (surface/bulk) reactive sites and self-adaption ability against consecutive conversion reactions. The microscopic hydroxy anion replacement against F– framework also reduces the Fe–F coordination strength while partially substituting “tough” LiF by “soft” LiOH in discharge products. Consequently, the optimized cathode delivers a good cycling performance (255 mAh g–1 after 150 cycles) at 100 mA g–1 and outstanding capacity retention from 200 to 1000 mA g–1 (with reversible capacity of 327 mAh g–1). Such structural design method also reveals new perspectives for the expansion and exfoliation of graphite and its confinement effect and hybridization with electrode active species.
多电子转换型和经济友好型氟化铁被标记为锂驱动电池的潜在阴极候选者，而不是单电子氧化还原嵌入氧化物。在此，我们提出了熔融-灌注-氟化策略，将焦绿相铁羟基氟化引入天然石墨层。宏观上的珊瑚状形态、Fe-C化学键夹心填充和三维开放框架赋予FeF3丰富的（表面/体）活性位点和连续转化反应的自适应能力。微观羟基阴离子对F -骨架的取代也降低了Fe-F配位强度，同时放电产物中“软”LiOH部分取代了“硬”LiF。因此，优化后的阴极在100 mA g-1下具有良好的循环性能（150次循环后255 mAh g-1），并且在200至1000 mA g-1（可逆容量为327 mAh g-1）之间具有出色的容量保持能力。这种结构设计方法也为石墨的膨胀和剥落及其约束效应和与电极活性物质的杂交提供了新的视角。

Abstract Plantar temperature and pressure reflect the plantar health status of diabetic patients and serve as critical indicators for evaluating disease progression. However, existing plantar monitoring devices are still limited by single-modal signal acquisition, bulky device configurations, and a strong reliance on external power supplies. Herein, we report a thermogalvanic hydrogel-based smart insole integrating self-powered sensing units for self-decoupled plantar monitoring. The insole integrates 16 self-decoupled thermogalvanic hydrogel sensing units, which convert plantar temperature difference and pressure stimuli into decouplable electrical signals via the thermogalvanic effect and the active iontronic piezoresistive effect, respectively. The incorporation of the backend acquisition circuit into the smart monitoring insole enables remote plantar temperature-difference and pressure mapping. Cloud-based machine learning further empowers the insole to assess plantar status in diabetic patients and distinguish disease-associated gait patterns. This work provides a versatile strategy for developing multimodal intelligent wearable platforms for personalized foot health monitoring and disease management.

Abstract Hyperlipidemia compromises implant integration, but the molecular mechanisms linking dyslipidemic environments to the biomaterial performance remain largely unknown. Here, we identify interfacial charge remodeling as a key regulator of the protein-mediated cell adhesion. Fibronectin (FN) is shown to govern endothelial attachment under hyperlipidemic conditions through charge-dependent interactions with the material surfaces. Molecular dynamics simulations reveal that the local charge distribution governs FN adsorption and conformational stability, while total internal reflection fluorescence (TIRF) single-molecule tracking demonstrates that charged adhesion domains regulate FN residence and adhesion stability in lipoprotein-rich environments. Deletion of negatively charged residues stabilizes FN–surface interactions, attenuates lipid-dependent disruption of adhesion signaling, and enhances endothelial responses. Similar charge-dependent behavior is observed on poly(lactic acid) (PLA), extending this interfacial charge remodeling from inorganic to organic biomaterials. These findings establish interfacial charge as a molecular determinant of implant integration under hyperlipidemic conditions and provide a general strategy for designing metabolism-responsive biomaterials.

Abstract The transport of flexible polyelectrolytes through nanoscale confinements is fundamental to polymer physics and biophysics, yet direct observation remains challenging. Using a nanopipette-based single-molecule nanomanipulation platform, we controllably translocate long single-stranded DNA (ssDNA) through a solid-state nanopore, enabling real-time tracking of chain dynamics with nanoscale precision. We discover that ssDNA generates a characteristic progressive current decrease with terminal oscillations─absent for rigid double-stranded DNA. Evidence indicates this signal arises from inner-tip access-resistance modulation by the ssDNA coil, with a linear relationship between current blockade and relative escape displacement. Systematic variation of voltage and nanopore geometry reveals electric-field-driven stretching of the ssDNA coil and extended interaction with the inner tip region. This provides a framework for interpreting flexible polyelectrolyte transport under nanoconfinement, with implications for polymer physics, nuclear pore transport, and intrinsically disordered proteins.

Abstract Neutral group-IV vacancy (XV, X = Si, Ge, Sn, and Pb) centers in diamond are promising solid-state spin-photon interfaces owing to favorable spin coherence and inversion-symmetry-protected optical transitions. However, stabilizing their neutral charge state typically requires stringent Fermi-level engineering in high-purity boron-doped diamond, which poses significant materials-growth challenges. Here, dimensional confinement in diamane offers an alternative for charge-state stabilization without intentional doping. Our results show that diamane thickness and surface chemical termination cooperatively tune the electronic structures of XV centers, while their neutral-state thermodynamic stability is enhanced. The zero-field splitting and spin–orbit coupling of XV centers could be tuned while largely preserving their optical transition energies. We find hydrogenated diamane offers the best balance between charge-state stability and magneto-optical performance. More broadly, our findings establish dimensional confinement as a general strategy for engineering the charge, optical, and spin properties of solid-state quantum defects.
金刚石中中性族iv空位（XV, X = Si, Ge， Sn和Pb）中心具有良好的自旋相干性和保护反转对称性的光学跃迁，是一种很有前途的固体自旋光子界面。然而，稳定它们的中性电荷状态通常需要在高纯度掺硼金刚石中进行严格的费米级工程，这给材料的生长带来了重大挑战。在这里，金刚石中的尺寸限制提供了一种无需故意掺杂的电荷状态稳定的替代方法。结果表明，金刚石厚度和表面化学终止共同调节了XV中心的电子结构，增强了它们的中性态热力学稳定性。XV中心的零场分裂和自旋轨道耦合可以在很大程度上保持其光学跃迁能的情况下进行调谐。我们发现氢化金刚石在电荷态稳定性和磁光性能之间提供了最好的平衡。更广泛地说，我们的发现建立了维度限制作为设计固态量子缺陷的电荷、光学和自旋特性的一般策略。

Abstract Transparent radiative-cooling windows can reduce cooling demand while preserving daylighting, yet high solar transmission becomes undesirable under strong solar irradiation. Although existing electrochromic windows can regulate solar transmittance, simultaneously achieving strong solar rejection, radiative heat dissipation, and wide-gamut coloration remains challenging. Here, we develop dynamic colorful radiative cooling windows by integrating planar coupled nanocavities with reversible silver electrodeposition. Electrochemically controlled Ag deposition/stripping reconfigures Fabry–Pérot resonances, enabling reversible switching between colored transparent and highly reflective colored opaque states while retaining high mid-infrared emissivity. The devices can achieve >40% modulation in average visible transmittance and cover 99.5% of the sRGB color gamut. Under outdoor conditions, they exhibit temperature drops of ∼7.0 °C compared to conventional glass and ∼8.7 °C relative to commercial electrochromic glass. This work provides a versatile platform for dynamic optical regulation with diverse requirements, paving the way for next-generation multifunctional smart windows, building envelopes, and smart photonic devices.

Abstract Interlayer modulation of layered oxychalcogenide superlattices provides a strategy to decouple electron–phonon transport for high-performance thermoelectric (TE) materials. Herein, an intercalated oxychalcogenide superlattice (La4Bi2Ag2Se2Te2O6) is theoretically designed by inserting a La2O2Te slab into the BiAgSeO framework to synergistically optimize carrier and phonon transport behaviors and systematically uncover an unprecedented synergy of orbital-driven valence band degeneracy and Ag+ liquid-like ionic dynamics. The La4Bi2Ag2Se2Te2O6 superlattice exhibits a highly anisotropic lattice architecture characterized by strong intralayer covalent bonding and weak interlayer interactions, which simultaneously preserves structural stability and promotes pronounced lattice anharmonicity. Meanwhile, stereochemically active Bi 6s2 lone-pair electrons, four-phonon scattering, and phonon–diffuson conversion drastically suppress the lattice thermal conductivity. This work establishes a dual-regulation intercalation paradigm combining band convergence and liquid-cation dynamics, offering a universal route for designing high-efficiency layered TE materials.

The La4Bi2Ag2Se2Te2O6 superlattice exhibits a highly anisotropic lattice architecture characterized by strong intralayer covalent bonding and weak interlayer interactions, which simultaneously preserves structural stability and promotes pronounced lattice anharmonicity. Meanwhile, stereochemically active Bi 6s2 lone-pair electrons, four-phonon scattering, and phonon–diffuson conversion drastically suppress the lattice thermal conductivity. This work establishes a dual-regulation intercalation paradigm combining band convergence and liquid-cation dynamics, offering a universal route for designing high-efficiency layered TE materials.","PeriodicalId":53,"journal":{"name":"Nano Letters","volume":"37 1","pages":""},"PeriodicalIF":10.8,"publicationDate":"2026-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149210021","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}
