Metal sulfides, one kind of electrode material with very high theoretical capacity, have been widely studied for use in lithium and sodium ion batteries. However, there are some problems hindering their applications in electrodes, such as low conductivity and volume expansion. The MOF introduces metals with different coordination strengths into an existing MOF structure, which improves the performance of the electrode to a certain extent. In this paper, Fe/Zn bimetallic MOF rod-like superstructure was prepared based on Ostwald theory. Accompanied by sulfuration, the MOF was effectively combined with MoS2 and GO, and the objective materials Fe7S8-C/ZnS-C@MoS2/rGO composites were successfully prepared. The MOF material provides a good frame and an efficient electron transport path, while the robust rGO wall effectively inhibits the pulverization of materials during the lithium/sodium intercalation/escalation courses. This particular material exhibited excellent cycling and rate capability performance when used in Li/Na-ion batteries. When used in Li-batteries, the electrode material delivered a specific capacity of 1598.3 mA h g−1 at 0.1 A g−1 and remained at 1196.7 mA h g−1 even after about 100 cycles and further exhibited a specific capacity of 368.68 mA h g−1 at the current rate of 5 A g−1 even after 1000 cycles, respectively. As for sodium batteries, these electrode materials exhibited an initial reversible capacity of 1053.6 mA h g−1 at 0.1 A g−1 and the reversible capacity was still as high as 592.2 mA h g−1 after 200 cycles. It is perhaps that this composite material with its particular architecture and composition is greatly beneficial for electron transfer and Li/Na ion diffusion. In the repeated physicochemical/nutrifying process, the appropriate distance between adjacent MOFs is of great help in preventing volume changes and thus improving the electrochemical performance.

High-voltage and low-cost manganese-based P 2-type oxides show real promise as promising cathode for sodium-ion batteries (SIBs). But the P 2 − O2 phase transformation and Na + /vacancy ordering results in the inferior structural stability and Na + diffusion coefficient , which further leads to rapid decay of capacity and poor rate capability. Herein, in consideration of the synergetic effects of dual cationic doping, electrochemically inactive Li + and active Co 3+ codoping are proposed to solve the above issues. The novel two-step doping strategy, Co doping during synthesis of precursors via coprecipitation reaction followed by Li doping during solid-state reaction, are rationally developed. As anticipated, the Li/Co codoped P 2-type oxide exhibits the absence of P 2 − O2 phase transformation and Na + /vacancy disordering, which gives rise to an outstanding cycling stability (86.7% capacity retention within 100 cycles at 0.1C) and high-rate capability (reversible capacity of 109 mAh g −1 even at 10C). In addition, the full-cells composed of the codoped P 2-type positive and hard carbon negative show high energy-density, good lifespan and high-rate property. This proposed cationic codoping provides an effective and scalable tactics for modulating the structural properties of high-voltage P 2-type cathodes for advanced SIBs.

Na₂CO₃-NaCl eutectic molten salt is used to enhance Ni/CC catalyst for CMD. • 97.6% CH₄ conversion is obtained over 20 h under a counter-current gas flow system. • High and stable activity arises from a triple synergistic effect of the salt system. • The molten salt achieves >99% recovery via simple water washing and evaporation. • Besides H 2 , carbon products are graphitic spheres and thin graphitic sheets. Catalytic methane decomposition (CMD) is a promising route for low-CO ₓ hydrogen production, but conventional solid catalysts suffer from rapid deactivation due to carbon encapsulation and metal sintering. Herein, we develop a low-cost, robust gas-liquid-solid triphasic system by integrating a Ni/coal-char catalyst with a Na₂CO₃-NaCl eutectic molten salt (with an optimized mass ratio of 6:4 and counter-current operation). At 850 °C, this system achieves a stable methane conversion of 97.6% over 20 h, with no obvious deactivation. The exceptional performance originates from a triple synergistic effect of the eutectic salt: (i) mass transfer enhancement via counter-current operation, (ii) interface protection that suppresses Ni sintering and directs carbon growth toward value-added graphitic structures, and (iii) potential electronic modulation via Ni 2+ -CO₃ 2− coordination that facilitates CH 4 activation and conversion. Furthermore, the molten salt can be recovered almost completely (>99%, as determined by titration), with 94.1% methane conversion maintained after five cycles. This work provides a promising strategy toward industrial hydrogen production and deepens the mechanistic understanding of physical-chemical synergy in molten salt-mediated CMD systems.

Against the backdrop of energy conservation and environmental protection, developing more stable and efficient phosphors has become an urgent challenge. In this study, we have synthesized a series of Ca2.5Hf2.5Ga3O12:Eu3+(CHGO:Eu3+) red phosphors via a high-temperature solid-state method, which exhibit strong red emission at 610 nm under 394 nm excitation, corresponding to the5D0→7F2transition of Eu3+. To improve the lattice vacancies caused by charge imbalance when Eu3+is doped into the CHGO lattice to replace Ca2+, we introduce the charge compensator M+(M = Li, Na, K). The results of the emission spectrum show that the introduction of charge compensators can effectively improve the luminescence intensity. Among them, K+has the most significant effect on increasing the emission intensity of Eu3+, making the emission intensity of the phosphor more than twice that when there are no charge compensation ions. Additionally, the quantum efficiency and thermal stability of these phosphors are significantly improved compared to the CHGO:0.075Eu3+sample before substitution. At 423 K, the emission intensity of the CHGO:0.075Eu3+, 0.075K+sample still remains at 88.7% of that at 298 K. The color rendering index of the prepared white LED is 81.2, and its CIE chromaticity coordinates are (0.3212, 0.3065). This indicates that the prepared CHGO:0.075Eu3+, 0.075K+red phosphor has broad application prospects in solid-state lighting.

Soil salinization severely restricts plant growth and threatens food safety. Silicon nanoparticles (SiNPs) can alleviate salt stresses, while the mechanisms remain unclear. Aiming for targeted application of SiNPs under soil salinization, silicate (Si) was selected as reference Si source, and the effects of Si and SiNPs on plant growth, photosynthetic performance, antioxidant performance, and ionic homeostasis in cucumber under salt stress were comprehensively investigated with the usage of principal component analysis (PCA) and transcriptome sequencing. In general, salt stress induced significant growth inhibition in cucumber, with decreased biomass and root morphological parameters, while both Si and SiNPs alleviated growth inhibition in cucumber. In addition, Si and SiNPs application at high concentration more effectively enhanced Na/K homeostasis, and low concentration application of Si and SiNPs induced a more significant regulation on antioxidant enzyme activities. In addition, SiNPs induced a more extensive regulation on gene expression network than Si in response to salt stress in cucumber, which was supported by the results of enrichment analysis. Moreover, correlation analysis between key modules of weighted gene co-expression network analysis (WGCNA) and physiological traits implied that genes related to chloroplast functions, redox balance, and membrane transport processes could be the key targets of SiNPs. Overall, the results showed that Si and SiNPs promoted salt stress resistance in cucumber with a dose-dependent pattern. SiNPs application more effectively promoted cucumber biomass and regulated gene expression network than silicate under salt stress, while several key target genes of SiNPs in modulating salt stress in cucumber were also identified. The results would provide a basis of targeted application of SiNPs under soil salinization.

To address the issues of poor cycling stability and unrealized theoretical capacity of layered molybdenum disulfide (MoS 2 ) as an anode material—caused by severe volume expansion during charge/discharge processes—we innovatively propose a "partial carbonization" modification strategy for ZIF-8 templates. This approach successfully constructs a ZnS/NC "dodecahedral nursery" rich in active sites. Benefiting from the abundant anchoring sites provided by this structure, MoS 2 can uniformly and firmly "take root" on the "nursery" via Mo–N bonds, ultimately forming a composite material (ZnS/NC@MoS 2 ) in which MoS 2 nanoflowers uniformly coat the dodecahedral framework. This composite effectively mitigates the volume expansion of MoS 2 and enhances overall structural stability. Moreover, the zinc retained by the partial carbonization strategy, after sulfidation, contributes additional capacity via conversion reactions, further enhancing the material's electrochemical performance. Specifically, when used as an anode for lithium-ion batteries (LIBs), it maintains a specific capacity of 895.64 mAh g −1 after 1200 cycles at 2 A g −1 ; for sodium-ion batteries (SIBs), its specific capacity increases from 348 mAh g −1 to 510 mAh g −1 after 500 cycles at 1 A g −1 .

Salt stress disrupts photosynthesis, ion homeostasis,
and antioxidant
systems, thereby inhibiting plant growth and reducing the yield and
quality. This study investigated the physiological and molecular mechanisms
of salt stress alleviation by foliar application of different concentrations
of silicon dioxide nanoparticles (SiO 2 NPs) in oats under
150 mM NaCl. Physiological and transcriptomic analyses were performed.
300 ppm of SiO 2 NPs significantly promoted growth and photosynthesis,
enhanced antioxidant enzyme activities, reduced oxidative damage,
and maintained Na + /K + balance while improving
nutritional quality. SiO 2 NPs regulated genes involved
in photosynthesis and carbon metabolism and upregulated the ion transporter
genes HKT1;1 , HKT7 , and HKT9 and ROS signaling genes MPK6 and WRKY33 . HKT proteins were localized to the plasma membrane.
Weighted correlation network analysis (WGCNA) identified six hub genes
associated with the growth and photosynthetic traits. Overall, SiO 2 NPs enhance salt tolerance, yield, and quality in oat by
maintaining Na + /K + homeostasis, activating ROS
signaling, and sustaining photosynthesis and carbon metabolism.

This study explored the influences of L-Arg in the ion migration and the quality of low-salt fish balls (L, 0.3 % NaCl). L-Arg significantly increased the weight gain and expansion rate of L by 18.33 % and 13.47 %. Water-holding capacity decreased from the internal to the external part of fish balls, consistent with the looser microstructure. Inductively coupled plasma-mass spectrometry (ICP-MS) revealed that L-Arg promoted Na + migration at setting ( P < 0.05), decreased the internal concentration from 34.38 to 30.37 mg/L and increased the external one from 25.78 to 29.80 mg/L ( P < 0.05). Conversely, Cl − concentration was decreased at setting and improved after the two-stage heating ( P < 0.05), indicating the suppressed Cl − migration. The partial replacement of Na + by L-Arg facilitated the protein unfolding, formation of disulfide bonds and exposure of tryptophan residues. This study enriched the mechanisms of salt reduction and quality maintenance for surimi products regarding ion migration.

Solid-state sodium batteries offer new opportunities for emerging applications with sensitivity to safety and cost. However, the prevailing composite electrolyte structure, as a core component, is still poorly conductive to Na ions. Herein, a 3D architecture design of Na + conductive Na 3 Zr 2 Si 2 PO 12 framework is introduced to in situ compound with polymer electrolyte, subtly inducing an anion-enriched interface that acts as rapid ion immigration channel. Multiple continuous and fast Na + transport pathways are built via the amorphization of polymer matrix, the consecutive skeleton, and the induced anion-adsorbed interface, resulting in a high ionic conductivity of 4.43 × 10 −4 S·cm −1 . Notably, the design of 3D skeleton not only enables the content of inorganic part exceeds 60 wt% without any sign of agglomeration, but also endows the composite electrolyte reach a high transference number of 0.61 by immobilizing the anions. The assembled quasi-solid-state cells exhibit high practical safety and can stably work for over 1500 cycles with 83.1% capacity retention. This tactic affords new insights in designing Na + conductive composite electrolytes suffering from slow ion immigration for quasi-solid-state sodium batteries. Graphical abstract

Cr4+-activated phosphors are important candidate materials for NIR-II light sources, but providing a suitable lattice coordination environment for Cr4+ and achieving long wavelength broadband emission remains a challenge. In this work, a series of Cr4+-activated ABO2 (A = Li, Na; B = Al, Ga) phosphors were successfully prepared. Due to the presence of only tetrahedral coordination structures available for Cr4+ to occupy in the matrix crystal ABO2, the valence state and luminescence stability of Cr4+ are effectively guaranteed. Through the cation substitution design of A-site (Na → Li) and B-site (Ga → Al), the [BO4] tetrahedron is distorted and expanded, which degrades the symmetry of the Cr4+ coordination crystal field. Consequently, the central wavelength of the Cr4+ emission peak is tuned from 1280 to 1430 nm, and the fwhm is significantly extended from 257 to 355 nm. Thebroadband NIR-II light sources constructed with LiAlO2: 0.03Cr4+ and NaGaO2: 0.03Cr4+ phosphors verify their important potential applications in nondestructive testing and biological imaging.

In this work, a flexible and self-supporting P-doped carbon cloth (FPCC), which is composed of interwoven mesh of hollow microtubules with porous carbon walls, is prepared via a vacuum-sealed doping technology by employing the commercially available cotton cloth as sustainable and scalable raw material. When directly used as binder-free anode for sodium-ion batteries, the as-prepared FPCC delivers superior Na-storage properties in terms of specific capacity up to 242.4 mA h g–1, high initial Coulombic efficiency of ∼72%, excellent rate capabilities (e.g., 123.1 mA h g–1 at a high current of 1 A g–1), and long-term cycle life (e.g., ∼88% capacity retention after even 600 cycles). All these electrochemical data are better than the undoped carbon cloth control, demonstrating the significance of P-doping to enhance the Na-storage properties of cotton-derived carbon anode. Furthermore, the technologies of electrochemical impedance spectroscopy and galvanostatic intermittent titration technique are implemented to disclose the decrease of charge transfer resistance and improvement of Na-migration kinetics, respectively.

The practical uses of magnesium-ion batteries are hindered by their poor rate capability and fast capacity decay. Moreover, traditional sodium ion batteries suffer from serious safety problems resulting from the sodium dendrites formed on the anode. In order to circumvent these problems, we designed a highly reversible Na+/Mg2+ hybrid-ion battery composed of a metallic Mg anode, a TiS2 derived titanium sulfide cathode and a 1.0 M NaBH4 + 0.1 M Mg(BH4)2/diglyme hybrid electrolyte. The battery showed remarkable electrochemical performances with a large discharge capacity (200 mA h g−1 at the 1C rate), high rate capability (75 mA h g−1 at the 20C rate) and long cycle life (90% capacity retention after 3000 cycles). Moreover, it exhibited excellent safety properties due to dendrite-free Mg deposition of the anode and the high thermal stability of the cathode. These merits demonstrate the great potential of the reported Na+/Mg2+ hybrid-ion battery for large-scale energy storage.
