However, this process suffers from uncontrolled intermediate particle coarsening and the resultant sluggish oxygen-ion diffusion kinetics. To address this, we engineered a novel hierarchically porous Nb₂O₅ (HPS-Nb₂O₅) cathode with interconnected macropores (∼10² μm), mesopores (∼10¹ μm), and micropores (submicron). Electrochemical analyses coupled with potentiostatic electrolysis reveal a four-step reduction pathway of Nb₂O₅ in molten Na₃AlF₆-K₃AlF₆-AlF₃ salts: Nb₂O₅→Na₂Nb₈O₂₁/NbO₂→NbO→Nb, where solid-state oxygen diffusion remains rate-limiting. The novel cathode pore architecture optimizes the solid-liquid interfaces between the cathode and the electrolyte, facilitating uniform insertion of Na⁺/F⁻ ions into cathode particles to generate intermediate particles. Consequently, rhombohedral Na₂Nb₈O₂₁ intermediate with uniform size and morphology was formed, thereby effectively preventing the excessive coarsening of intermediate particles and associated oxygen diffusion path elongation that occurs in the conventional electro-deoxidation processes. Remarkably, complete reduction of 1 g Nb₂O₅ to Nb powder was achieved in only 1.5 h at 2.5 V. This represents an 8-13-fold efficiency enhancement over the reported processes. The resultant niobium powder exhibits uniform submicron particles (200-500 nm) with near-spherical morphology. This pore-structure-regulated strategy overcomes fundamental bottlenecks in the FFC process and offers broad applicability for the efficient preparation of diverse refractory metals and alloys.","PeriodicalId":305,"journal":{"name":"Electrochimica Acta","volume":"39 1","pages":""},"PeriodicalIF":6.6,"publicationDate":"2025-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145009528","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Moisture-electric generators (MEGs) are capable of converting this latent heat into electricity without environmental constraints. However, the key to promoting the large-scale application of MEGs lies in the development of active materials and the optimization of device structure. In this work a new type of MEG was constructed utilizing an ionic hydrogel and vermiculite-cellulose nanofiber/carbon nanotube (VM-CNF/CNT) composite membrane. The specific asymmetric structure enables a dynamic balance between moisture absorption and water evaporation, generating a humidity gradient and an ion concentration gradient within the composite membrane, thereby producing a continuous electric current. At 90% RH, a single device can generate an open-circuit voltage (<em>V</em><small>_OC</small>) of approximately 0.60 V and a continuous short-circuit current (<em>J</em><small>_SC</small>) of about 19.6 μA cm<small>⁻²</small>. Notably, the device can provide output current to a 1 MΩ load for 150 hours. Through simple parallel configurations, the integrated modules with 15 single MEGs can generate a stable current of 750 μA.

Ionic liquids are a viable alternative to conventional carbonate solvents due to their thermal stability and electrochemical window. This work reports the performance of LNMO/Li half cells with an ionic liquid electrolyte (ILE) composed of 0.79 molal LiFSI in trimethyl isobutyl phosphonium bis-fluorosulfonyl imide (P111i4FSI). The long-term stability of the cells cycled at 25 °C in ILE is superior compared to all the other cycling conditions, as shown by the Coulombic efficiency (>99.5%) and capacity retention after 210 cycles (>87.9%). Spectroscopy measurements showed that the LNMO in the LP40 cycled cells had severe structural damage, with visible holes in the surface region of the particle, extending 15-20 nm away from the surface. On the other hand, the structure of the LNMO used in the cells with ILE was similar to that of the pristine spinel after 210 cycles, the only difference being a rock-salt layer on the surface. The surface chemistry of the LNMO particles was analyzed by electron energy-loss spectroscopy and revealed that the surface region of the LNMO cycled in LP40 adopted a (MnxNiy)3O4-type structure in the previously described holes, while the surface chemistry was nearly unaffected by cycling in ILE. XPS highlighted the influence of the electrolyte on the nature of the cathode electrolyte interface (CEI), which showed the presence of a predominantly organic CEI after cycling in LP40. The CEI formed after cycling in ILE was thinner and dominated by species like Li2CO3 and salt decomposition products. Overall, the cycling stability of LNMO with LiFSI in P111i4FSI was improved, and the structural integrity was maintained with this electrolyte, as opposed to the conventional LP40.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"31 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2025-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145008801","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, we achieve this target through an in situ copolymerization of vinyl ethylene carbonate (VEC) together with acrylonitrile (AN) under fitting ratios inside a porous polyacrylonitrile (PAN) fiber membrane doped with flame-retardant decabromodiphenyl ethane (DBDPE) molecules. The received fiber-reinforced polycarbonate-based composite electrolyte with an ultrathin thickness of 13 μm exhibits good internal interfacial compatibility because of the same AN structure and superior flame-retardant performance due to the doped DBDPE molecules. The dual lithium salt strategy facilitates the formation of a stable interface layer on the lithium anode surface. The electrolyte also exhibits high thermal stability, a high ion transference number (0.75), a wide voltage window (up to 4.9 V), and high ionic conductivity (6.3 × 10-4 S cm-1 at room temperature). As a result, its Li//Li symmetric cells could maintain stable cycling for over 2500 h, and its LiFePO4//Li full cells also exhibit an initial capacity of 135 mAh g-1 and a retention of 82.9% after 300 cycles at 2 C and 25 °C.

We report a multicolor CPL-emitting elastomeric film (P37/PSK@SiO₂-PDMS) that synergistically combines chiral helical polyacetylene (P37) and a surface-engineered perovskite (PSK@SiO₂) through hydrogen-bond-directed assembly. Confinement within the PDMS matrix drives P37 to self-assemble into a chiral supramolecular structure through hydrogen bonding, inducing a chiroptical inversion. Simultaneously, surface modification of PSK@SiO₂ enhances its compatibility with PDMS while enabling efficient chirality and energy transfer from P37 via interfacial hydrogen bonds. The resulting material exhibits exceptional CPL performance, achieving a maximum dissymmetry factor of 4.3 × 10^–2 and a high photoluminescence quantum yield up to 67%. The PDMS matrix not only stabilizes the PSK components but also enables reversible, strain-tunable CPL modulation through its elastomeric properties.

However, this process faces significant challenges, including the difficulty of N₂ activation, high energy barriers, and low selectivity. In this study, we theoretically designed a Ni triple-atom doped Cu₂O catalyst, Ni TAC@Cu₂O, which exhibits exceptional urea synthesis performance. Using density functional theory and the constant potential method, we show that the superior catalytic performance of Ni TAC@Cu₂O stems from synergistic metal–support interactions (MSIs) between Ni atoms and Cu₂O. Cu₂O serves as an anchoring substrate and actively participates in CO₂ activation via strong Cu–O bonding, whereas Ni serves as the pivotal active center for N₂ activation. Ni TAC@Cu₂O achieves a moderate N₂ adsorption energy and a limiting potential (U_L) of −0.60 V, overperforming Ni single-atom (Ni SAC@Cu₂O, U_L = −0.85 V) and Ni double-atom (Ni DAC@Cu₂O, U_L = −0.88 V) catalysts. The third Ni atom enhances electron donation, reducing the energy barrier of the rate-determining step (*CO + *N₂ + H⁺ + e^– → *CONNH), while O atoms in Cu₂O regulate Ni’s electronic structure through MSIs. Additionally, Ni TAC@Cu₂O demonstrates thermodynamic, electrochemical, and acid–base stability and effectively suppresses competing side reactions. This work underscores the importance of Cu₂O-supported MSIs in multiatom catalysts for enhanced performance and provides insights for advanced electrocatalyst design.","PeriodicalId":21,"journal":{"name":"ACS Nano","volume":"372 1","pages":""},"PeriodicalIF":17.1,"publicationDate":"2025-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145009161","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}

One of the required parameters that is challenging to specify in the analysis of solidification cracking by most of the common criteria is the bridging liquid fraction (<em>f_l,brid</em>), which refers to the liquid fraction below which solidification cracking susceptibility (SCS) reduces. A model was developed based on the interfacial energies and solidification microstructure size to calculate <em>f_l,brid</em> across different alloy compositions and, in turn, accurately predict the solidification cracking behavior. The higher sensitivity of grain boundaries to cracking compared to dendritic boundaries inside the grain can be easily shown with the model. The model also accurately predicts the composition with the highest cracking susceptibility (C_SCSmax) in various binary aluminium alloy systems. Furthermore, based on this model, changes in C_SCSmax under different processing conditions (i.e., thermal gradient and solidification rate) were accurately predicted by accounting for changes in microstructure size and possible back diffusion occurrence. The model was verified with independent experimental reports and original laser welding experiments.","PeriodicalId":238,"journal":{"name":"Acta Materialia","volume":"86 1","pages":""},"PeriodicalIF":9.4,"publicationDate":"2025-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145009424","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}

Spectroscopic analyses (XRD, FTIR, and XPS) confirmed the unique monoclinic fergusonite-type structure, wherein Nb exhibits a distorted tetrahedral coordination with oxygen- a unique characteristic that significantly contributes to its superior catalytic performance. When employed to modify screen-printed carbon electrode (YNbO₄/SPCE), the material exhibited markedly improved electron transfer kinetics, as evidenced by significantly higher reduction currents and lower overpotentials compared to the bare SPCE. The developed sensor displayed an ultra-low detection limit (10.4 nM), a wide linear detection range (0.049 – 960.23 μM), high sensitivity, and remarkable selectivity against common interfering species.
