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.

A ‘Critical’ Insight into Pretransitional Behavior and Dielectric Tunability of Relaxor Ceramics

The model discussion focused on links between the unique properties of relaxor ceramics and the basics of Critical Phenomena Physics and Glass Transition Physics is presented. It indicates the significance of uniaxiality for appearing mean-field type features near paraelectric – ferroelectric transition. Pretransitional fluctuations, increasing up to grain size and leading to inter-grain, random, local electric fields, are indicated to be responsible for relaxor ceramics characeristics. Their impacts yield the pseudospinodal behavior associated with ‘weakly discontinuous’ local phase transitions. The emerging model re-defines the meaning of the Burns temperature and polar nanoregions (PNRs). It offers a coherent explanation of ‘dielectric constant’ changes with the ‘diffused maximum’ near paraelectric – ferroelectric transition, the sensitivity even to moderate electric fields (tunability), and the ‘glassy’ dynamics. These considerations are confronted with experimental results for the complex dielectric permittivity studies in Ba0.65Sr0.35TiO3 relaxor ceramic, covering ca. 200K range, from the paraelectric to the ‘deep’ ferroelectric phase. The distortions-sensitive and derivative-based analysis revealed the preference for the exponential scaling pattern for ℇ(T) changes in the paraelectric phase and in the surrounding of the paraelectric-ferroelectric transition. It may suggest the Griffith-phase type behavior, associated with the mean-field criticality disturbed by random local impacts. The discussion of experimental results is supplemented by relaxation times changes and the coupled energy losses analysis. The studies also led to the description of tunability temperature changes with scaling relations. © 2023, CC BY.

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

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

Unravelling the Effect of Alkali Metal Deposition on Co3o4 for Catalytic Decomposition of N2o

Herein, the effect of alkali metal deposition on the catalytic performances of Co3O4 for N2O decomposition was studied through experimental and density functional theory calculation. It is determined that the introduction of these alkali metal, such as K, Rb and Cs seriously inhibits the reduction of Co3+ to Co2+, thereafter decreasing the electron donor capacity and oxygen vacancy, and thereby suppressing the catalytic activity of these catalysts for decomposing N2O. In sharp contrast, the deposition of Na perceptibly promotes the transfer of electron and weakens the Co-O bond, thereafter increasing the ratio of Co2+/Co3+, Oads/Olatt, as well as the content of reducible Co species. As a result, the catalytic activity of Na-Co3O4 for directly catalytic N2O decomposition is significantly improved in the region of 250~490 ℃. Therefore, the finding here may shine light on the deep understanding of alkali metal deposition on Co-based catalysts for directly catalytic N2O decomposition. © 2022, The Authors.
