Herein, a 3D nanoflower-like NiFe-LDH/MOF heterostructured electrocatalyst based on MXene is successfully prepared by an in situ semi-transformation (ISST) strategy. Chemical probe tests and pH-dependent tests indicate that the introduction of defects in the catalysts reduce the energy of the metal-oxygen bond and promote the release of lattice oxygen during the OER process, further enhancing the LOM pathway. Density Functional Theory (DFT) calculations also demonstrated that electronic coupling at heterogeneous interfaces and defect engineering optimised the adsorption process of the reaction intermediates and markedly improved the intrinsic catalytic activity. As expected, the catalysts exhibited good electrochemical performance, with HER and OER requiring only 143 mV and 176 mV. In addition, the overall water-splitting tests indicate that merely 1.55 V of cell voltage is needed for the catalyst to attain a current density of 10 mA cm⁻². Excellent stability is also observed at high current densities, demonstrating its potential to be used as a bifunctional catalyst for large-scale industrialized applications.</div></div>","PeriodicalId":10660,"journal":{"name":"Composites Part B: Engineering","volume":"298 ","pages":"Article 112356"},"PeriodicalIF":12.7,"publicationDate":"2025-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143562823","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}

Kink-bands are structural defects and are particularly sensitive to physical and biological stresses, on isolated fibres or in bio-based composite materials. To this end, a panel of archaeological samples from different time periods and preserved under different environmental conditions were selected and studied using synchrotron micro-tomography. It is demonstrated that although kink-bands are generally more numerous in ancient fibres, their degree of severity is sometimes less. This underlines the importance of fibre extraction methods, which are principally responsible for kink-band formation. The results also show that kink-band are weaknesses points, allowing rapid development of internal porosity (up to 25 %) when the fibres are used or stored in extreme environments, and that this porosity can also extend to healthy areas of the fibres. However, in some cases, even after millennia of conservation, it appears that the fibres can present morphologies comparable to modern samples, probably due to their good initial quality. Thanks to the findings of the present work, simplified schemes of degradation in kink-band zones, useable on single fibres but also in composite materials, are proposed. These results confirm the importance of fibre extraction processes on fibre quality and durability, and subsequent use for sustainable and high-performance composite materials and textiles.</div></div>","PeriodicalId":10660,"journal":{"name":"Composites Part B: Engineering","volume":"298 ","pages":"Article 112347"},"PeriodicalIF":12.7,"publicationDate":"2025-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143552816","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, organic-inorganic double-walled microcapsules were synthesized through the biomimetic mineralization method.

The microcapsules showcased triggering properties in simulated pore solutions of cementitious material.

This innovative structure differs significantly from conventional networked or diffusely distributed reinforcement structures. Specifically, we develop a core-shell structure within the WC/TiAl composite, where C atoms produced by the reaction between WC and the TiAl matrix are dispersed and solidly dissolved in the matrix alloy. Some W atoms enrich the matrix to form β₀/B2 phases, while others are solidly dissolved near the lamellar colony boundary, creating a continuum shell-like structure. The lamellae within the lamellar colony act as a core. This W-rich shell structure impedes dislocation movement through solid solution strengthening and further restricts dislocation slip by reducing the stacking fault energy (SFE) and promoting the creation of SFs and twins during deformation. The low diffusion rate of refractory W helps prevent the softening of the lamellar colony boundaries at high temperatures. Notably, we report for the first time the long-period stacking ordered (LPSO) structure during high-temperature deformation of powder metallurgy TiAl-based composites, which further hinders dislocation motion and mitigates high-temperature softening. The WC/TiAl composites exhibit outstanding high-temperature strengths, with an ultimate tensile strength (UTS) of 730 MPa at 800 °C, maintaining 728 MPa at 900 °C.
