Abstract ：
Herein, we report a hydrogen-bonded supramolecular hybrid composed of a cobaloxime complex and a covalent organic framework (COF) that achieves photocatalytic overall water splitting. The designed COF features ternary units and dual linkages, which induce asymmetric linkers. Upon photoexcitation, this asymmetry facilitates directed electron transfer and spatially separated redox sites, resulting in a long-lived charge-separated state. Consequently, the COF, hydrogen-bonded with cobaloxime as a hydrogen (H2) production cocatalyst, enables visible-light photocatalytic overall water splitting, simultaneously producing H2 and hydrogen peroxide (H2O2), outperforming the COFs with symmetric linker structures. This strategy of asymmetric structural design offers new insights for the design of photocatalysts with suppressed charge recombination for photocatalysis.

Abstract ：
Herein, a versatile amorphous-to-crystalline transformation (ACT) strategy is described, to furnish various metals (Cu, Co, Ni, Cs, and Y) based atomically dispersed catalysts (ADCs) on thin holey 2D Al2O3. This approach, which involves adjusting reactant stoichiometry, enables the continuous modulation of particle size of ADCs at an atomical level, giving the ultrafine products as single atom, cluster, or nanoparticle catalysts. This synthesis method allows a straightforward analysis and comparison of the reactivity of the ADCs catalysts based on the dispersion of the active metal. In the case of Cu, the cluster catalyst 0.2-Cu/Al2O3 outperforms the single atom catalyst 0.1-Cu/Al2O3 and the nanoparticle catalyst 0.3-Cu/Al2O3 in the oxidation of refractory organic molecules, thanks to its superior electron transport and surface adsorption properties. These findings are well supported by the Density functional theory (DFT) calculations. Additionally, this method facilitates the preparation of atomic clusters with a very small size of 0.5-1 nm, composed of just a few atoms, as exemplified by Ni-based ADCs. The developed synthesis enriches the library of ADCs and demonstrates the potential of amorphous-to-crystalline transformation in creating advanced ultrasmall functional materials.

Abstract ：
In this study, divalent calcium cation with large radius and trivalent yttrium cation with small radius were introduced to develop co-stabilized zirconia ceramics with both superior mechanical properties and aging resistance. Through a reverse coprecipitation-hydrothermal method, a series of ultrafine xCaO-yY2O3-ZrO2 (x = 2.0, 3.0, y = 0.5, 1.0, 1.5, 2.0) raw powders with high quality were fabricated for the production of nanostructured ceramics via low-temperature pressurelessly sintering. The sintering process was optimized by investigating the effects of sintering temperature on densification, grain growth and phase evolution. The minimally doped 2.0CaO-0.5Y2O3-ZrO2 ceramic retained pure tetragonal phase at room temperature, achieving a balance of excellent toughness and high aging resistance. The impacts of chemical composition on microstructure, hardness, toughness and aging resistance were examined for these xCaO-yY2O3-ZrO2 (x = 2.0, 3.0, y = 0.5, 1.0, 1.5, 2.0) ceramics. The segregation of calcium and yttrium cations at grain boundaries effectively tailored the microstructure. It was observed that substituting small trivalent yttrium cations for large divalent calcium cations effectively enhanced the aging resistance without sacrificing mechanical properties, due to the strengthened grain boundaries and asymmetrical distribution of cations among grains. This work not only produces low-doped zirconia ceramics with both excellent mechanical properties and aging resistance, but also presents straightforward method for preparation of high-quality raw powders and delicate microstructural engineering during sintering for developing advanced structural ceramics. © 2025 Elsevier Ltd and Techna Group S.r.l.

Abstract ：
An ideal solid-state electrolyte needs to combine the properties of high ionic conductivity, wide electrochemical stability window, high electrode-electrolyte chemical compatibility, and low cost. Composite solid-state electrolyte is one of the feasible ways to solve this problem. In this work, a composite solid-state electrolyte Li2ZnSiO4 (LZSO)/ LiAlCl4 is reported. The low melting-point LiAlCl4 is introduced to solve the interfacial impedance problem of LZSO solid-state electrolyte due to the hardness of the particles. The structure and electrochemical properties of the two compositions were also characterized, and the effects of different composite ratios on the ionic conductivity of the composite solid-state electrolyte and the low-temperature healing surface structure on the performance enhancement were investigated. The optimal ratio LZSO/LiAlCl4 (7:3) exhibits good interfacial contactness and an ionic conductivity of 1.65 x 10(-4) S cm(-1) at 60 degrees C as well as a low activation energy of 0.31 eV. The assembled lithium symmetric batteries were stably cycled up to 750 h. Compared with the single component of LZSO, which cannot satisfy the full-cell assembly, Li/LFP batteries assembled with composite solid-state electrolytes exhibit good cycling performance.

Abstract ：
Halide solid electrolytes receive much attention due to their electrochemical properties, such as high ionic conductivity, oxidative stability, and ease of preparation. In this work, a bromide solid electrolyte LiBiBr4, exhibiting ease of processing and high ionic conductivity, is designed for the first time and investigated through a comparative investigation with monoclinic LiAlCl4 and LiAlBr4 for the migration path. The processing pressure for LiBiBr4 with annealing at 120 degrees C is less than one-tenth that of other chloride electrolytes (approximate to 5 MPa). Computational analyses unveil crucial mechanistic insights into the three migration mechanisms and the factors that influence them within the monoclinic structure. The distribution and distance of non-Li polyhedrons to the migration pathways are pivotal for the migration. The strategic positioning of the Bi polyhedron in LiBiBr4 is far from the Li+ pathway. The unique leap migration within the LiBiBr4 has a lower energy barrier and facilitates an interconnected migration that forms a 3D interstice network. This interconnected leap migration network within LiBiBr4 constitutes a Z-type interstice leap migration along the ab-axis. Thus, the LiBiBr4 obtains a high ionic conductivity of 0.19 mS cm(-1) with the 0.349 eV low activation energy. This discovery and research methods provide significant impetus and support for the development of halogen-based electrolytes.

Abstract ：
In the quest to align with industrial benchmarks, a noteworthy gap remains in the field of electrochemical nitrogen fixation, particularly in achieving high Faradaic efficiency (FE) and yield. The electrocatalytic nitrogen fixation process faces considerable hurdles due to the difficulty in cleaving the highly stable NN triple bond. Additionally, the electrochemical pathway for nitrogen fixation is often compromised by the concurrent hydrogen evolution reaction (HER), which competes aggressively for electrons and active sites on the catalyst surface, thereby reducing the FE of nitrogen reduction reaction (NRR). To surmount these challenges, this study introduces an innovative bimetallic catalyst, CuGa2, synthesized through p-d orbital hybridization to selectively facilitate N2 electroreduction. This catalyst has demonstrated a remarkable NH3 yield of 9.82 mu g h-1 cm-2 and an associated FE of 38.25%. Our findings elucidate that the distinctive p-d hybridization interaction between Ga and Cu enhances NH3 selectivity by reducing the reaction energy barrier for hydrogenation and suppressing hydrogen evolution. This insight highlights the significance of p-d orbital hybridization in optimizing the electrocatalytic performance of CuGa2 for nitrogen fixation.

Abstract ：
Conventional aqueous zinc-ion batteries (AZIBs) encounter challenges that compromise the reversibility and stability of the zinc anode. To mitigate these issues, this study proposes the incorporation of highly polar 1,2-propylene glycol (PG) as a co-solvent. PG's capacity to form hydrogen bonds with water molecules effectively reduces water activity and facilitates uniform Zn2+ deposition by establishing a negatively charged adsorption layer via PG molecules. By optimizing the water-to-PG ratio, a tailored electrolyte system was developed, and the electrochemical behavior of Zn2+ during the solvation-to-deposition process was systematically elucidated through experimental and theoretical analyses. The findings indicate that AZIBs incorporating 20 % PG achieve a cycle life of 2500 h at a current density of 1 mA cm- 2 and a capacity of 1 mA h cm- 2, underscoring the pivotal role of PG in stabilizing the zinc anode interface. The assembled Zn||VO2 full cells demonstrated exceptional performance in the 20 % PG electrolyte, sustaining 1100 stable cycles even at a high rate of 20C. Moreover, AZIBs with 20 % PG exhibited superior ionic conductivity at low temperatures, enabling Zn||Zn symmetric cells to operate stably for 2500 h at-20 degrees C. These results highlight the significant potential of 20 % PG in practical energy storage systems.

Abstract ：
Overcoming the challenges of integrating disparate components in nanoarchitectures, this study introduces a straightforward strategy based on a mixed-valence coordination approach, creating an ordered ternary heterostructure integrated with ultrasmall homojunction. This singular ordered homojunction-heterostructure unites ultrathin 1D rutile TiO2 nanowires (NWs) and ultrathin anatase TiO2 NWs with 0D Prussian Blue Analogs (PBAs) nanoparticles (NPs), all exhibiting crystallographic oriented alignment with each other, forming a ternary mesocrystals. Experimental and theoretical insights disclose that the complex interplay between these dissimilar components is governed by a spontaneous lattice match effect, which not only optimizes but also directs the charge transfer, thereby enhancing both efficiency and stability. It also allows for tailoring the valence states of Fe within the PBA, fine-tuning of the composite's photochromic properties, and introducing abundant defect structures that foster strong interaction with oxygen molecules, enabling controllable color-switching dynamics. Consequently, the FeII1-xFeIIIx-PBA/TiO2 exhibits an optimized ternary structure of R-TiO2/A-TiO2/PBA, demonstrating exceptional photoelectronic properties, significantly enhancing photochromism and secure encryption capabilities. These insights establish a solid foundation for engineering sophisticated complex-ordered nanoarchitectures, advancing sustainable energy and environmental technologies.

Abstract ：
Hydrogels possess significant potential for the development of multifunctional soft materials in smart sensors and wearable devices, attributed to their distinctive properties of softness, conductivity, and biocompatibility. Nevertheless, their widespread application is frequently limited by inadequate mechanical strength and strain capacity. This study introduces a meticulously engineered hydrogel system, LM/SA/P(AAM-co-BMA), which integrates eutectic gallium-indium alloy (EGaIn) as both a polymerization initiator and a flexible filler. The resultant hydrogel demonstrates remarkable tensile strain capabilities of up to 2800% and a tensile strength of 2.3 MPa, achieved through a synergistic interplay of ionic coordination, hydrogen bonding, and physical polymer interactions. Furthermore, the hydrogel exhibits outstanding biocompatibility, recyclability, and stable long-term storage, rendering it an ideal candidate for the continuous monitoring of high-intensity physical activities.

Abstract ：
Single-atom catalysts (SACs) anchored on defective supports offer exceptional catalytic efficiency but face challenges in stabilizing isolated metal atoms and optimizing metal-support interactions. Here, a defect-driven strategy is reported to construct a 3D dendritic SAC comprising interwoven ultrathin TiO2 nanowires (NWs) with abundant oxygen vacancies (OVs) that stabilize atomically dispersed cobalt (Co) sites. Using hydrothermal synthesis followed by acid etching and calcination, Ti & horbar;Co & horbar;Ti motifs are engineered at OVs site. The 3D architecture provides multiscale porosity and charge transport, achieving syngas production rates of 28.4 mmol g(-1)h(-1) (CO) and 13.9 mmol g(-1)h(-1) (H-2) with a high turnover frequency (TOF) of 10.6 min(-1), surpassing many other state-of-the-art Co-based SACs. In situ Raman and electron paramagnetic resonance (EPR) analysis reveal OVs consumption during Co anchoring, while density functional theory (DFT) validates charge redistribution from Ti to Co, enabling efficient electron transfer and inducing strong electronic interactions that enhance CO2 adsorption and activation. The results highlight the interplay between atomic-scale coordination environments and macroscale architectural order in harnessing the catalytic potential of SACs and ultrathin 1D NWs.
