Designing composite photocatalytic systems with nanoscale precision is crucial. While conventional facet-selective photo-deposition successfully utilizes spherical co-catalysts, the directed deposition of pre-synthesized two-dimensional (2D) materials onto specific facets remains extremely challenging. This work demonstrates an electrostatic assembly strategy for the precise deposition of 2D transition metal carbides (MXenes) onto anisotropic single-crystal semiconducting metal oxides. By precisely controlling the solution pH, we modulated the surface charge of the MXenes and the distinct crystallographic facets of the metal oxides, enabling selective deposition driven by electrostatic attraction. Negatively charged Mo_4/3C MXenes were selectively deposited on the electron-rich (101) surface of TiO₂ at pH 3, the (100) surface of Cu₂O exposed at pH 11, and the (010) surface of BiVO₄ at pH 1.5. The high facet selectivity was confirmed through a combination of advanced techniques, including electron microscopy, electron spectroscopy, and synchrotron-based spectromicroscopy. This selective interfacial engineering promotes spatially separated charge carrier migration toward distinct facets, while Schottky barriers form at the MXenes/oxides interfaces. The MXenes act as efficient reduction co-catalysts, facilitating the rapid consumption of electrons, thereby enhancing photocatalytic hydrogen evolution. This work establishes a generalizable, non-photolytic method for integrating challenging 2D co-catalysts with facet-engineered semiconductors for designing composite photocatalysts.

Tendon regeneration requires materials that dynamically adapt to the healing stages, offering mechanical support, adhesion prevention, inflammation control, and collagen remodeling. We introduce a novel, dynamically adaptive piezoelectric hydrogel designed to address these requirements. The hydrogel features a bioinspired, anti-adhesive lotus structure to minimize fibroblast and protein adhesion, preventing postoperative complications. Furthermore, it incorporates rationally designed gradients in piezoelectricity, mechanical properties, and degradation rate. These gradients allow the hydrogel to dynamically match the evolving needs of tendon healing, providing adjustable mechanical, electrical stimulation, and controllable degradation. The hydrogel demonstrably reduces inflammation (downregulating TNF-α), promotes M2 macrophage polarization, inhibits bacterial growth, and stimulates endogenous tendon regeneration. This regeneration is characterized by increased collagen I deposition, improved fiber alignment, and enhanced biomechanical properties. Transcriptomic analysis revealed upregulation of genes associated with mechanotransduction, tissue remodeling, and anti-inflammatory responses, alongside downregulation of fibrotic and oxidative stress pathways. This self-powered, multi-gradient scaffold represents a significant advancement in tendon tissue engineering, offering a promising strategy for tendinopathy treatment.

Developing fast, reversible, and recyclable thermal switches is essential to advance adaptive thermal management. Here, we present a strain-tunable thermal switch based on largely amorphous olefin block copolymer (OBC) fibers, achieving a continuous switching ratio above 2 over 1000 cycles, as well as very short response times below 0.22 s. Using Raman spectroscopy, we quantify vibrational delocalization with increasing strain and demonstrate its direct connection to the observed thermal conductivity changes. We show that unlike prior assumptions linking propagating heat carriers primarily to crystalline domains, alignment in amorphous systems can enable phonon-like modes that dominate transport. To our best knowledge, this work is the first to experimentally probe vibrational delocalization using Raman spectroscopy and to demonstrate that alignment alone can govern the dominant carrier in disordered polymers. These findings establish design strategies for fatigue-resistant, high-performance, and recyclable polymer thermal switches for advanced thermal energy transport applications.

Ultrafast and reliable visual perception is essential for obstacle avoidance in autonomous driving, where split-second decisions must be made in complex, high-speed environments, yet remains constrained by the limited temporal resolution and processing latency of conventional devices. Here, inspired by the exceptional temporal resolution of falcon vision systems (>150 Hz), we develop a neuromorphic vision sensor capable of ultrafast, edge-selective perception for dynamic traffic scenarios. The sensor leverages vertically stacked, edge-rich SnS₂/MoS₂ van der Waals heterostructures, in which a high density of atomic-scale interfaces and defective edges enables enhanced light-matter interactions and rapid carrier dynamics. These structural advantages endow the Falcon Vision Sensor (FVS) with synaptic plasticity (PPF = 201%, LTP = 1300s), high refresh rate (250 Hz), and intrinsic erasure behaviors, closely mimicking the temporal precision and motion discrimination features of falcon vision. When the synaptic devices are integrated with computing modules, the system achieves real-time obstacle detection, along with a directional motion recognition accuracy of 98.89%. This work demonstrates a robust biologically inspired visual intelligence, offering a compact, low-latency solution for next-generation autonomous vehicles and edge AI applications requiring rapid environmental responsiveness.

The construction and integration of curvature govern the structure and function of materials based on 2D sheets, yet achieving ultrafast and scalable curvature programming remains a major challenge. We rapidly generate large stress mismatches by combining an ultrafast stress-relaxing diselenide-containing polyurethane with an ultraslow stress-relaxing disulfide-containing polyurethane. Coupled with modular components and compression, this mismatch enables localized, directional loading of high stress with excellent scalability. Using this strategy, 2D polymer sheets achieve 180° bending within 10 s of UV irradiation, yielding a curvature-programming rate 15-fold faster than state-of-the-art methods. Furthermore, origami modules, which display a 37-fold enhancement in compressive performance, can be obtained through mass production and assembled into complex 3D architectures. This rapid, high-curvature programming approach offers efficiency, mechanical robustness, and scalability, advancing the practical deployment of origami-based metamaterials.

The lack of physiologically relevant in vitro models remains a limitation in liver transplantation research. Progress in organ-on-a-chip technologies enables the generation of clinically translatable data in vitro. A vascularized liver tissueoid-on-a-chip (LToC) model is engineered to replicate human liver tissue's structural and functional features for modeling liver regeneration and allograft rejection. The LToC comprises a microfluidic device containing donor-matched human hepatic progenitor cells and intrahepatic portal vein endothelial cells embedded in a fibrin matrix and maintained in dynamic culture for 49 days. The system supports self-assembly into a perfusable microvascular network and liver lobule-like architecture, with >95% cell viability, stable vascular integrity, and active hepatic function (albumin, urea, complement factors, and hepatocyte growth factor secretion). The mature tissueoid includes hepatocytes (CK18⁺, albumin⁺, CYP2D6⁺), cholangiocytes (CK19⁺, EPCAM⁺), Kupffer cells (CD68⁺), stellate cells (PDGFR-β⁺), and endothelial cells (CD31⁺). Perfusion with allogeneic T cells induces cellular rejection, characterized by decreased viability, endothelial disruption, hepatic marker loss, HLA-I upregulation, and a proinflammatory cytokine response (IL-6, TNF-α, IL-1β, IFN-γ, granzyme A and B, and perforin). The LToC provides a physiologically relevant platform for studying immune-mediated liver injury, tissue regeneration, and allograft rejection, with potential applications in immunosuppressive drug testing and personalized transplant medicine.

The practical deployment of lithium sulfide (Li₂S) cathodes in all-solid-state lithium-sulfur batteries (ASSLSBs) is challenged by their poor innate conductivities and high activation barriers. Here, we demonstrate a lattice engineering strategy using Zr⁴⁺ substitution to fundamentally activate Li₂S. The introduced Zr⁴⁺ expands the lattice, creating lithium vacancies that enhance ionic conductivity by two orders of magnitude. Simultaneously, Zr─S orbital hybridization narrows the bandgap for superior electronic conductivity and weakens Li─S bonds to lower the activation energy. This synergistic effect enables a highly reversible solid-state sulfur conversion. As a result, our ASSLSB delivers an ultrahigh energy density of 996.2 Wh kg⁻¹ based on the cathode with a record 65 wt.% electrode-level Li₂S content and maintains stability for over 100 cycles, far exceeding the conventional configuration of ∼40 wt.% loading. This strategy establishes a viable pathway toward practical high-energy-density ASSLSBs by fundamentally activating Li₂S electrochemistry.

With the continuously decreasing levelized cost of renewable electricity, electrocatalytic waste treatment and valorizations have attracted increasing attention as sustainable routes for converting waste molecules into valuable chemicals. Here, we report an energy-efficient strategy that couples nitrate-reduction (NO₃R) with sulfide-oxidation reaction (SOR) to simultaneously remediate pollutants and produce value-added chemicals. By utilizing a dual-catalyst composite in which cobalt polyphthalocyanine (CoPc) and copper polyphthalocyanine (CuPc) are co-anchored on carbon nanotubes, we achieve enhanced cathodic ammonia (NH₃) production that is well matched with efficient anodic thiosulfate formation. This paired NO₃R-SOR system enables the direct synthesis of ammonium thiosulfate, a valuable fertilizer feedstock, via simple mixing of the anolyte and catholyte. Kinetic analysis reveals that the improved NH₃ production originates from a relay of the ^*NO₂ from Cu- to Co-sites, allowing both active-sites to bypass their respective rate-limiting steps. Based on these insights, we demonstrate an integrated NO₃R||SOR system that substantially lowers the required cell voltage compared with conventional NO₃R||OER (oxygen evolution reaction) systems, achieving a 64% reduction in energy consumption at 200 mA cm⁻². Preliminary techno-economic analysis further suggests a substantial increase in energy-normalized product value, highlighting a sustainable approach for coupled waste treatment and chemical production.

Efficient oxygen reduction reaction (ORR) requires coordination of oxygen adsorption, transport, and catalysis at active sites. Yet most studies address only one step, overlooking whole-pathway O₂ regulation and thus limiting performance. Here, we report a bioinspired Co-doped Fe₂P on N-doped carbon featuring a hierarchical eucalyptus-like nanoarchitecture, engineered to regulate oxygen throughout the electrochemical cycle, where Fe–P–Co hetero-coordinated bridges anchored to the carbon substrate through Fe─N bonds induce strong electronic coupling and polarization. The hierarchical structure generated local electric fields that enriched OH⁻ and O₂, while multilevel porosity accelerated oxygen transport. This enabled coordinated optimization of oxygen adsorption, transfer, and active-site electronic configuration. This nanohybrid achieved a half-wave potential of 0.938 V vs. RHE, sustained discharge in Al-air batteries for 373 h, and delivered an energy density of 3487 Wh/kg. Theoretical simulations revealed that Co-doping shortened Fe─P bonds and tuned the Fe electronic environment, lowering the d-band center and weakening Fe 3d-O 2p interactions, which reduced the *OH desorption barrier and accelerated ORR kinetics. In situ Raman spectroscopy revealed that Fe–P–Co bridges served as active centers facilitating *OH release during ORR. These findings indicate that integrating hierarchical architecture, hetero-coordinated Fe–P–Co bridges, and electronic-state modulation enables whole-pathway O₂ management for efficient oxygen electrocatalysis.

Here, we report a bioinspired Co-doped Fe2P on N-doped carbon featuring a hierarchical eucalyptus-like nanoarchitecture, engineered to regulate oxygen throughout the electrochemical cycle, where Fe–P–Co hetero-coordinated bridges anchored to the carbon substrate through Fe─N bonds induce strong electronic coupling and polarization. The hierarchical structure generated local electric fields that enriched OH− and O2, while multilevel porosity accelerated oxygen transport. This enabled coordinated optimization of oxygen adsorption, transfer, and active-site electronic configuration. This nanohybrid achieved a half-wave potential of 0.938 V vs. RHE, sustained discharge in Al-air batteries for 373 h, and delivered an energy density of 3487 Wh/kg. Theoretical simulations revealed that Co-doping shortened Fe─P bonds and tuned the Fe electronic environment, lowering the d-band center and weakening Fe 3d-O 2p interactions, which reduced the *OH desorption barrier and accelerated ORR kinetics. In situ Raman spectroscopy revealed that Fe–P–Co bridges served as active centers facilitating *OH release during ORR. These findings indicate that integrating hierarchical architecture, hetero-coordinated Fe–P–Co bridges, and electronic-state modulation enables whole-pathway O2 management for efficient oxygen electrocatalysis.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":"90 1","pages":""},"PeriodicalIF":29.4,"publicationDate":"2026-02-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146138748","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}

Electromagnetic metasurface integrated microfluidic chips enable a real-time, label-free platform for terahertz trace analysis of volume-limited biomedical samples with suppressed water absorption noise. However, conventional metal-insulator-metal (MIM) metasurface resonators exhibit inherently limited Q-factor and sensitivity due to radiative leakage through open side boundaries. Here, a lattice slot waveguide based on MIM configuration is designed to effectively confine energy within the microfluidic channel and mitigate radiative loss. This trapped mode achieves enhanced sensitivity and Q-factor through synergistic excitation of surface lattice resonance and guided mode resonance under propagation constant matching conditions. Leveraging this platform, an anisotropic detection strategy incorporating a patterned lattice structure is devised to achieve simultaneous polarization multiplexed responses, exhibiting a figure of merit of 135 in both polarizations. Experimental validation demonstrates a limit of detection of 625 pmol mL⁻¹ and a Q-factor of 189 for this polarization multiplexing microfluidic platform. This work offers a unique avenue for enhanced accuracy and efficiency in terahertz biomedical trace analyzing via multidimensional sensing capabilities.
