Industrial water-alkali splitting is facing high energy consumption due to the high overpotential of commercial Ni mesh anode in oxygen evolution reaction (OER) processing. Herein, a simple ball-milling-assisted laser scanning strategy was employed to introduce the hardest Lewis acid chromium (Cr) into the Ni matrix to form Cr2Ni3 catalysts supported by Ni mesh, endowing such NiCr/Ni mesh anode a robust OER performance at a low-cost. It is shown that facilitating the self-adsorption of oxygen species and promoting the leaching of soluble Cr cations aids in reconstructing Ni cations into active (oxy)hydroxide species. This study explores the innovative development of Cr-doped NiCr/Ni mesh catalysts to create porous NiCr/Ni alloys with Cr2Ni3 as the active phase. The optimal Ni0.5Cr0.5-NM electrode demonstrates ultra-low overpotentials of 293 mV and 321 mV at 50 and 100 mA cm−2, respectively, while maintaining excellent stability for over 100 hours at 100 mA cm−2. This work provides insight into the batch fabrication of customized OER anodes for sustainable hydrogen production. © 2025 Wiley-VCH GmbH.

The difference in electrochemical behavior between reinforcement and metal matrix usually damages the corrosion resistance of composites. Herein, the coherent BNNSs-AlN-Al transition interface is creatively constructed in the Aluminium-Boron nitride nanosheets (Al-BNNSs) system based on reactive sintering. It is demonstrated that BNNSs/Al composites exhibit good corrosion resistance via interfacial modification. The BNNSs-AlN-Al transition interface not only optimizes the interfacial structure of BNNSs/Al composites but also significantly enhances the interface bonding strength. Many low-angle grain boundaries (LAGBs) are induced during extrusion due to the pinning effect of strong bonding transition interface. Besides, density functional theory (DFT) calculation and geometric phase analysis (GPA) were executed to clarify the influence of interface design on the corrosion behavior of BNNSs/Al composites. It is found that the transition interface and LAGBs have strong valence electron constraint ability, thus weakening the galvanic effect in composites. Also, the construction of the transition interface reduces the geometrically necessary dislocations and lattice distortion in the grains of Al matrix, avoiding the decrease of corrosion potential of Al matrix. Ultimately, the coupling effect between LAGB and transition interface not only significantly enhances the ion erosion resistance of composites, but also shifts the corrosion mechanism from intergranular corrosion (IGC) to pitting corrosion (PC) in Al matrix. The current work provides a feasible route for the design of aluminum matrix composites (AMCs) with high corrosion resistance.

Charge density wave (CDW) and their interplay with correlated and topological quantum states are at the forefront of condensed matter research. The 4Hb−TaS2 is a CDW ordered quantum heterostructure that is formed by alternative stacking of Mott insulating 1T-TaS2 and Ising superconducting 1H-TaS2. While the 13×13 and 3×3 CDWs have been respectively observed in the bulk 1T-TaS2 and 2H-TaS2, the CDWs and their pivotal role for unconventional superconductivity in the 4Hb−TaS2 remain unsolved. In this Letter, we reveal the two-dimensional (2D) 13×13 chiral CDW in the 1T layers and intraunit cell coupled 2D 2×2 CDW in the 1H and 1H' layers of 4Hb−TaS2. Our results establish 4Hb−TaS2 a 2.5D quantum heterostructure, where 2D quantum states emerge from 3D crystalline structure.

All-solid-state lithium-based batteries (ASSLBs) with good safety and high energy density are valuable. To realize stable and high-efficiency ASSLBs, high-performance solid-state electrolytes (SEs) with good processability are necessary. Bromide (Br)-based rare-earth halide SEs (RE-HSEs) exhibit good deformability for large radii of RE and Br ions. Here, the influence of RE ions on the crystalline structure and mechanical properties of Br-based RE-HSEs (RE = Y, Gd, Tb, Ho, or Er) was analyzed in detail, and Li3GdBr6 (LGdB) showed the softest lattice and the best deformability due to having the longest RE-Br bond length. Furthermore, LGdB exhibits satisfactory ionic conduction ability (1.4 mS cm-1), and the assembled ASSLBs exhibit a reversible redox process, excellent fast-charging performance, and superior cycling stability for 6000 cycles at 10 C. This study indicates that the relationship between the RE and deformability of Br-based RE-HSEs is significant for the rational design and improvement of HSEs in ASSLBs. © 2025 American Chemical Society.

Shape-adaptive, deformable and adhesive hydrogels enable stable closure of long incision wounds

Effective closure of long incision wounds is crucial in clinical practice but remains challenging for existing bioadhesives due to the deformations of the long incisions. Herein, we propose a concept of shape-adaptive adhesion and achieve it by designing a class of shape-adaptive, deformable adhesive hydrogels (DAHs) for long incision wound closure. The design strategy is facile yet universally applicable, which involves aldehyde polysaccharides as adhesive primers and microgel-type gelators as building blocks. We demonstrate that the microgel-type gelators are responsible for the integration of a deformable matrix in situ, and aldehyde polysaccharides enhance the adhesive performance of the matrix at cost of a little deformability. Optimization of the flexibility of DAH network is effective in balancing the adhesive and deformable properties, thus developing DAHs featured with the adaptability to irregular shapes, robust adhesive properties, and appropriate deformability. As a result, DAHs achieve shape-adaptive adhesion by effectively bonding the long incision and deforming with it without failure. In vivo results clearly show that DAHs stably close the 4 cm-long incision wounds on the backs and the more dynamic incisions on the napes of rats. The shape-adaptive adhesion achieved by DAHs may provide an alternative way for long incision wound treatment. Statement of significance: Bioadhesive is emerging as an effective tool in clinical wound treatment. However, the closure of severe long incision wounds by currently available bioadhesives is still challenging. In this work, we proposed a concept of shape-adaptive adhesion and accordingly developed a bioadhesive building strategy for long incision wound closure. The strategy is universally applicable, which involves aldehyde polysaccharide as an adhesive primer and microgel-type gelators as building blocks. The results showed that the strategy is effective in developing bioadhesives (DAHs) that simultaneously posses
