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.

Understanding material behavior under varying stress and strain rates is key to improving design integration and reliability in critical sectors like defense and manufacturing. An innovative multi-dimensional honeycomb array gradient flyer (HAGF) is introduced to enable precise control over stress–strain rates, representing a significant advancement in material design. For the first time, LS-DYNA simulations uncover the detailed mechanisms of shock wave propagation, attenuation, and convergence by adjusting element numbers and spacing. Based on the proposed shock wave propagation mechanism, a multi-dimensional graded structure was designed and fabricated using projection microstereolithography (PμSL) with controlled polymerization, resulting in a defect-free structure with a tip size of 41.2 μm–67.5 % smaller than previous designs. This innovation enables controlled loading within low-stress (GPa) and strain-rate (10 4 –10 5 /s) ranges, providing a novel methodology for evaluating material dynamic responses in extreme environments. These findings provide a new technical foundation for improving material performance in demanding applications.

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.

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.

This work presents the functionalization of ceramic membranes with novel modifiers to enhance the immobilization efficiency and catalytic performance of Candida antarctica lipase B (CALB). Three newly synthesized urea-based silane modifiers − Si-C 3 H 6 -U-CH 2 CH 3 , Si-C 3 H 6 -U-CH 2 NH 2 , and Si-C 3 H 6 -U-NHCH 3 , were grafted onto Al 2 O 3 powders and ZrO 2 planar ceramic membranes and compared with a commercial alkylsilane (Si-C 8 H 17 ). Comprehensive physicochemical characterization confirmed successful grafting with high efficiency (up to 98 %), tunable surface hydrophobicity, and nanometric control over grafted layer thickness (1.11–1.44 nm). Enzyme immobilization was performed via physical adsorption, and performance was evaluated using a model enantioselective transesterification of (R,S)-1-phenylethanol. Among the tested surfaces, Si-C 3 H 6 -U-CH 2 CH 3 demonstrated the highest lipase loading (0.41 mg) and superior catalytic activity (initial conversion rate: 104 μmol h −1 ), significantly outperforming the commercial modifier (Si-C 8 H 17 ). Enhanced activity correlated with increased surface hydrophobicity, facilitating the lipase’s open conformation and active site accessibility. The membranes also displayed distinct zeta potential profiles and adhesion characteristics, indicating that terminal functional groups play a crucial role in enzyme affinity and surface interaction. Reusability studies revealed that the Si-C 3 H 6 -U-CH 2 CH 3 -functionalized membranes retained 81 % of their initial activity after two cycles, though activity declined to 31 % after five cycles − likely owing to enzyme desorption from the membrane surface. These findings highlight the interplay between surface chemistry, enzyme interaction, and catalytic performance, offering a pathway for tailoring membrane supports for biocatalytic applications. This work provides a valuable insight into designing next-generation enzyme-functionalized membranes for sustainable chemical pr

In this work, a fast(0.5 h), green microwave-assisted synthesis of single crystalline Sb_2Se_3 nanowires was developed. For the first time we demonstrated a facile solvent-mediated process, whereby intriguing nanostructures including antimony selenide(Sb_2Se_3) nanowires and selenium(Se) microrods can be achieved by merely varying the volume ratio of ethylene glycol(EG) and H_2O free from expensive chemical and additional surfactant. The achieved uniform Sb_2Se_3 nanowire is single crystalline along [001]growth direction with a diameter of 100 nm and a length up to tens of micrometers. When evaluated as an anode of lithium-ion battery, Sb_2Se_3 nanowire can deliver a high reversible capacity of 650.2 m Ah g^(-1) at 100 mA g^(-1) and a capacity retention of 63.8% after long-term 1000 cycles at 1000 mA g^(-1), as well as superior rate capability(389.5 m Ah g^(-1) at 2000 mA g^(-1)). This easy solvent-mediated microwave synthesis approach exhibits its great universe and importance towards the fabrication of high-performance metal chalcogenide electrode materials for future low-cost, large-scale energy storage systems.

The robust porous architectures of active materials are highly desired for oxygen electrodes in lithium–oxygen batteries to enable high capacities and excellent reversibility. Herein, we report a novel three-dimensional replication strategy to fabricate three-dimensional architecture of porous carbon for oxygen electrodes in lithium–oxygen batteries. As a demonstration, ball-flower-like carbon microspheres assembled with tortuous hollow carbon nanosheets are successfully prepared by completely replicating the morphology of the nanostructured zinc oxide template and utilizing the polydopamine coating layer as the carbon *** used as the active material for oxygen electrodes, the three-dimensional porous architecture of the prepared ballflower-like carbon microspheres can accommodate the discharge product lithium peroxide and simultaneously maintain the ions and gas diffusion paths. Moreover, their high degrees of defectiveness by nitrogen doping provide sufficient active sites for oxygen reduction/evolution *** the prepared ball-flower-like carbon microspheres demonstrate a high capacity of 9,163.7 mA h g-1 and excellent reversibility. This work presents an effective way to prepare three-dimensional architectures of porous carbon by replicating the controllable nanostructures of transition metal oxide templates for energy storage and conversion applications.
