Complete mineralization of persistent organic pollutants in wastewater remains a formidable challenge. Here, we report the rational design of a ZIF-8-derived ZnO/polyaniline (PANI) S-scheme heterojunction synthesized via in situ oxidative polymerization. advanced characterizations confirm the S-scheme charge transfer mechanism within the ZnO/PANI heterojunction. The optimized composite achieves complete phenol mineralization within 60 min while concurrently generating H 2 O 2 at a rate of 0.75 mmol∙L −1 ·h −1 under simulated solar irradiation. Mechanistic studies verify that the S-scheme heterojunction retains strong redox potentials, driving the formation of reactive oxygen species for H 2 O 2 production and phenol degradation. This work establishes a universal design paradigm for MOF-derived inorganic/organic S-scheme heterojunctions, effectively coupling solar-driven energy conversion with environmental remediation.

Magnesium phosphate cement (MPC) is a bone repair material with good early strength, but its low flexural strength limits its application in bone defect regions subjected to multi-directional loads and repeated stresses. Traditional strategies for reinforcing inorganic bone cement, such as lamination, provide excellent mechanical strength but result in the deterioration of other properties. For instance, the reduction in injectability makes it difficult for the bone cement to fill irregular bone defect sites. Therefore, developing a bone cement with high strength, good operability, and biological activity remains a significant challenge. This study aimed to construct a triple-cured gel-based bone cement by incorporating polyurethane-sodium alginate (EPU-SA) emulsion into magnesium phosphate bone cement (TMPC), forming a structurally more continuous and stable interpenetrating triple network composite system (ES-T) during the hydration process. The in-situ reinforcement of TMPC was achieved through the dual effects of physical and chemical interactions. The results showed that the flexural strength of ES-T under humid conditions was 214 % higher than that of TMPC, reaching 50.5 MPa. Interface analysis between organic and inorganic components confirmed the bonding mechanism between the emulsion and bone cement and clarified the reinforcement mechanism. In addition, ES-T demonstrated promotive effects on cellular osteogenic differentiation and generation of new bone tissue by in vitro and in vivo experiments. © 2025 Elsevier Ltd and Techna Group S.r.l.

Amorphous thin films with high power density and breakdown strength satisfy the needs of advanced power electronic systems. Nonetheless, improving the energy storage density of amorphous films is critical for addressing the growing demand for electricity. We apply high spontaneous polarization BaTiO3 as the main component to make (1-x)Ba(Ti0.99Mn0.02)O3-xBiFeO3((1-x)BTM-xBF) thin films. Doping BiFeO3 (BF) synergistically boosts polarization. The introduction of amorphous phases and Mn ions enhances the breakdown strength. The results demonstrate that, at x = 0.10, the film can achieve both a high efficiency of 80.3 % and an excellent energy storage density of 111.3 J cm-3. Moreover, the film has a strong thermal stability within a broad range of 20 to 160 °C, as well as the cycling reliability is as high as 105 times. The present study offers a practical approach to develop film capacitors with outstanding energy storage capabilities. © 2025 Acta Materialia Inc.

Hierarchical assembly of arc-like fractal nanostructures not only has its unique self-similarity feature for stability enhancement but also possesses the structural advantages of highly exposed surface-active sites for activity enhancement, remaining a great challenge for high-performance metallic nanocatalyst design. Herein, we report a facile strategy to synthesize a novel arc-like hierarchical fractal structure of PtPd bimetallic nanoparticles (h-PtPd) by using pyridinium-type ionic liquids as the structure-directing agent. Growth mechanisms of the arc-like nanostructured PtPd nanoparticles have been fully studied, and precise control of the particle sizes and pore sizes has been achieved. Due to the structural features, such as size control by self-similarity growth of subunits, structural stability by nanofusion of subunits, and increased numbers of exposed active atoms by the curved homoepitaxial growth, h-PtPd displays outstanding electrocatalytic activity toward oxygen reduction reaction and excellent stability during hydrothermal treatment and catalytic process.

Fusion-based metal additive manufacturing (AM) is a technology that builds objects layer by layer, with rapid solidification referring to the quick transition of material from liquid to solid. During this process, solute trapping, a nonequilibrium effect characterized by velocity-dependent partition coefficient, significantly influences microstructure kinetics, morphology, and phase formation. This study utilizes the latest quantitative phase field (PF) model to systematically investigate the solute trapping, solute drag, and their effects on pattern formation during rapid solidification at velocities relevant to AM, in both one and two dimensions. Under different temperature gradients and pulling velocities, we observed that the growth mode transits from planar to cellular to dendritic, then back to cellular, and finally to planar, which is consistent with classic solidification theory. A solidification microstructure selection map is constructed based on PF simulations. Furthermore, we compared primary dendritic/cell spacing calculated by the PF model with theoretical models. The simulated morphologies and arm spacing showed good agreement with experimental observations for Al-4Si and Ti-20Nb alloys during rapid solidification. These results demonstrate the potential of the PF model for predicting and controlling microstructure formation under rapid solidification conditions in the melt pool of AM processes. © 2024, The Authors.

Creating synthetic interface from non-life materials to improve Shewanella stability and endow them with precise functionalities could revolutionize cell-based biotechnologies. Herein, a stable and cytoprotective biointerface on Shewanella surface are rapidly generated through immediate coordination complexes of TA and Fe (Ⅲ) ions. TA-Fe^Ⅲ-based biointerface engineered Shewanella cells can be endowed with extremophile properties of resistance to high temperature, osmotic stress, UV light and lysozyme, and can be released from TA-Fe^Ⅲ biointerface through the acidic condition-triggered decomplexation. Furthermore, various functional materials with abiotic properties like conductivity and magnetism can be induced onto surface of Shewanella through co-self-assembly with TA-Fe^Ⅲ interface.

High-contrast in vivo fluorescence imaging exploiting wavelengths beyond 1880 nm

Nature Communications 2025年第1期16卷 1-12页

作者： Li, Jiayi Xia, Qiming Wu, Tianxiang Zhang, Yuhuang Peng, Shiyi Li, Yifei Li, Yixuan Lin, Hui Zhang, Mingxi Qian, Jun State Key Laboratory of Extreme Photonics and Instrumentations Centre for Optical and Electromagnetic Research College of Optical Science and Engineering International Research Center for Advanced Photonics Zhejiang University Hangzhou China Department of General Surgery Sir Run Run Shaw Hospital Zhejiang University School of Medicine Hangzhou China State Key Laboratory of Advanced Technology for Materials Synthesis and Processing Wuhan University of Technology Wuhan China

The second near-infrared (NIR-II) window is widely acknowledged for its excellent potential in in vivo fluorescence imaging. Currently, NIR-II fluorescence imaging predominantly operates within the 900-1880 nm spectral range, while the region beyond 1880 nm has been disregarded due to the large light absorption of water. Based on a refined understanding of the effect of light absorption on imaging, we propose an approach that utilizes the previously neglected region surrounding the water absorption peak at ~1930 nm for imaging. Both simulations and experiments confirm that the water absorption contributes positively to imaging, enabling high-contrast in vivo fluorescence imaging in the 1880-2080 nm window. To further assess the applicability of this approach in different biological media, we extend our focus to fluorescence imaging in adipose tissue. This leads to the expansion of the imaging window to 1700-2080 nm, owing to the unique light absorption characteristics of adipose tissue. Our results demonstrate that the 1700-2080 nm region provides optimal imaging quality in adipose tissue, attributing to its moderate absorption and low scattering. This work advances our understanding of the interplay between light absorption and photon scattering in bioimaging, providing an insight for selecting optimal imaging windows to achieve high-contrast fluorescence imaging. © The Author(s) 2025.
