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

Transition metal sulfides (TMSs) exhibit high theoretical capacity as anode materials for lithium-ion batteries (LIBs) and sodium-ion batteries (SIBs). However, their practical application is severely hindered by poor cycling stability. In this study, Co 3 S₄/1T-MoS₂ heterostructure was confined on nitrogen-doped carbon nanosheets composite (Co 3 S₄/1T-MoS₂@NC) by high-temperature pyrolysis and hydrothermal sulfidation, using ZIF-67 as the precursor, modulated by a small-molecule carbon source. The heterostructure between Co 3 S₄ and 1T-MoS₂ synergistically enhances the electrical conductivity and rapid diffusion kinetics. The aggregation of MoS 2 nanosheets at the interface effectively enhances the electrochemical performance of the material, while the nitrogen-doped carbon generated at the interface provides additional active sites. This interface engineering and the formation of heterostructures endow the material with improved ion storage capabilities. The composite remains high specific capacities of 1192.2 mAh g⁻¹ for LIBs and 615.3 mAh g -1 for SIBs after 100 cycles at 0.1 A g -1 . The combination of enhanced charge transport and structural stability highlights the potential of the heterostructure strategy for next-generation high-performance alkali metal-ion batteries.

To overcome critical challenges in flexible aqueous zinc-ion batteries (AZIBs)—specifically zinc dendrite proliferation, recurrent side reactions, and electrolyte mechanical-electrochemical incompatibility—we engineered a hydrogel electrolyte (PZEC). Synthesized in one step, PZEC integrates polyacrylamide (PAM)/ZnSO₄ with synergistic enhancements from ethylene glycol (EG)-based deep eutectic solvent (DES) and sodium carboxymethyl cellulose (CMC Na). A synergistic multi-component modification strategy reconstructing the hydrogen bond network yielded concurrent, major gains in mechanical strength and electrochemical stability. Hydrogen bond deconvolution analysis revealed a 3.1 % increase in strong hydrogen bonds within PZEC, accompanied by a significant reduction in the phase transition temperature to −29.46 °C, indicative of enhanced bound water confinement and low-temperature adaptability. PZEC manifests excellent mechanical properties (90 kPa fracture stress, 1280 % elongation) while attaining high ionic conductivity (29.26 mS·cm −1 ) and zinc ion transference number (0.63) via zinc solvation sheath compression and guided ion transport. The Zn//Zn symmetric battery exhibited exceptional cycling endurance, operating for 700 h at 5 mA·cm −2 and over 2000 h at 0.5 mA·cm −2 . Notably, PZEC maintained superior rate performance and cycling stability at 0 °C, retaining high reversible capacity and near-100 % coulombic efficiency (CE) even under high-rate conditions. Consequently, this work outlines a new methodology for high-performance flexible AZIBs and delivers significant insights for hydrogen bond-functionalized electrolyte engineering.

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.

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.

Carbon materials derived from metal-organic frameworks have attracted increasing attention as anodes for energy storage. In this study, Fe, Ni-doped ZIF-8 is carbonized at high temperature to obtain bimetallic Fe and Ni modified tension -relaxed carbon (FeNi@trC). Fe and Ni have opposite structural modification effects when the metal ions are doped into the ZIF-8 dodecahedron. The obtained carbon material maintains the regular dodecahedron morphology, which means the relaxation of tension and strong thermal stability during annealing. Moreover, the presence of nickel enhances the carbonization degree and electrochemical stability of FeNi@trC, while the calcination of the tensive ZIF-8 precursor offers more defect sites. The discharge capacities of FeNi@trC materials are stable at 182.9 mAh·g−1 and 567.9 mAh·g−1 for sodium-ion batterie (SIB) and lithium-ion batterie (LIB) at 0.05 A·g−1. Compared with the current density of 0.05 A·g−1, the discharge capacity of SIB and LIB attenuates by 29.4% and 55.9% at 1 A·g−1, respectively, and the FeNi@trC shows good performance stability in the following cycles.

The properties of Pickering emulsions is affected by many factors, one of the most typical of which is the ionic environment. Existing studies have mainly focused on the effect of ions in the continuous phase on oil-in-water Pickering emulsions, and usually only single species of ions are studied. The water-in-oil Pickering emulsions are commonly used to encapsulate a variety of water-soluble functional substances, which often contain various of ions. Therefore, it is necessary to study the effect of ions in the internal phase on the properties of inverse Pickering emulsions. The inverse Pickering emulsions with an average droplet size of 100 μm were prepared using hydrophobized calcium carbonate particles. Subsequently, Na+ and Ca2+ were introduced into the internal phase to investigate their effects on the emulsion. The results show that the presence of Na+ can aggravate droplet coalescence, and Ca2+ can cause severe damage to the emulsions and even lead to phase inversion. It was speculated that Na+ can weaken the surface charge of particles by compressing the electric double layer, resulting in lower electrostatic repulsion between particles, thus changing the dispersion state of the particles and ultimately affecting the properties of the emulsion. And Ca2+ can combine with and release stearate from the particle surface through chemical reactions, thus changing the wettability of the particles and resulting in breaking and phase inversion of the emulsions. The present work is informative for the setting of the phase composition and the prediction of stability during the application of inverse Pickering emulsions.

As potential candidates, metal sulfides display strong storage abilities but suffer from serious volume swelling and polysulfide shuttling. Especially rich-sulfur materials, inferior reversible conversion reactions (from MS 2 to MS with S) can bring about major formation of sulfur. Herein, cubic-like Sn–Co–S materials with SnO 2 as catalyst are designed with various dimensional carbon. The as-resulted samples display uniform distributed particle size (≈5 µm), while cross-linked Sn–Co–S@carbon is successfully formed due to its rich surficial groups. Significantly, the formation of chemical bonds about Sn/Co–S–C is noted, facilitating ions/e-transfering and architecture enhancing. Meanwhile, owing to the endothermic effect of carbon, SnO 2 finally resulted, effectively limiting the so-called “shuttling effect” of polysulfide. Utilized as sodium-ion anodes, the optimized samples can deliver a capacity of 490 mAh g −1 at 0.5 A g −1 and ≈400 mAh g −1 above at 5.0 A g −1 . Assisted by the detailed kinetic analysis, it can be confirmed that the improvements of surface-controlling behaviors mainly come from the interfacial chemical bonds and strong-polar metal-oxides bonds. This work is expected to illustrate the roles of interfacial design and metal oxide catalysts for advanced energy storage materials.

In this study, to enhance the peroxymonosulfate (PMS)-assisted photocatalytic degradation of tetracycline (TC) under visible light over BiVO 4 , g-C 3 N 4 coupling and Na + doping was used to co-modify BiVO 4 to obtain g-C 3 N 4 /Na-BiVO 4 (CN/Na-BiVO 4 ) heterojunction catalyst. The prepared CN/Na-BiVO 4 exhibited the apparently enhanced PMS-assisted photocatalytic TC degradation efficiency and can degrade approximately 98.20% of TC in 40 min, being 3.13 folds of BiVO 4 . The boosted TC degradation over CN/Na-BiVO 4 was ascribed to the Z-scheme heterojunction formation, doped Na + , more V 4+ and oxygen vacancies resulting from Na + doping facilitate the electron-hole pairs migration and separation. Meanwhile, more V 4+ and oxygen vacancies generated in Na-BiVO 4 also promoted the PMS activation . Therefore, a large number of reactive oxygen species (ROSs), including •O 2 − , h + , •OH, SO 4 •− , and 1 O 2 , were produced in CN/Na-BiVO 4 +PMS+Vis system to degrade TC. The mechanism of enhanced PMS-assisted photocatalytic degradation of TC was proposed. This work further highlighted the advantages of the PMS-assisted photocatalytic technology in antibiotics removal and also demonstrated that g-C 3 N 4 coupling and Na doping co-modify BiVO 4 was one effective and feasible method for promoting the PMS-assisted photocatalytic degradation of TC under visible light.

Necklace-box structural FeS 2 /WS 2 carbon nano-composite fibers (NB FeS 2 /WS 2 -CNFs) are fabricated by electrospinning-sulfuration-hydrothermal process. NB FeS 2 /WS 2 -CNFs exhibit the spatial confined structure, which is able to restrain volume expansion effectively in the process of Na + intercalation/deintercalation and improve the cycling stability and rate performance. NB FeS 2 /WS 2 -CNFs exhibit remarkable initial coulombic efficiency (ICE = 87.0%) and stable long cycle (~422.6 mA h g −1 at 0.5 A g −1 after 500 cycles) for sodium storage capability. The heterojunction interface between FeS 2 and WS 2 can alleviate the damage of the micro-crystal plane and enhance electrochemical kinetic process. The structure evolution and mechanism of sodium storage are explored by ex-situ methods, which further confirm the spatial and interface confinement effect distinctly. In addition, the electrochemical kinetic properties of lithium-ion batteries (LIBs), sodium-ion batteries (SIBs) and potassium-ion batteries (PIBs) are compared, thereby revealing the energy storage mechanism and different ion migration modes of the three batteries. This work provides a guide for the synthesis of bimetallic compounds based on the spatial confinement and heterojunction interface confined strategy that efficiently improves energy storage performance of electrode material.

Na 3 V 2 (PO 4 ) 3 (NVP) has become a hot material in the research field of sodium-ion batteries (SIBs) as a result of its unique structural advantages. Unfortunately, the poor electronic conductivity and ion diffusion ability fundamentally limit the practical development of NVP. Considering the above defects, a series of Li + doped Na 3−x Li x V 2 (PO 4 ) 3 /C cathode materials for SIBs are synthesized through hydrothermal assisted sol–gel method. The cell volume steadily decline with the raise of Li + doping amount, which is consistent with the usual doping effect. Moreover, with the increase of lithium doping amount, Li + preferentially occupies Na (2) site and then occupies Na (1) site. Through the first principles calculation, it is clear that the introduction of Li + can significantly reinforce the conductivity of the material system and diminish the electron localization phenomenon. The analysis of (1 1 6) crystal plane by TEM shows that Li doping will reduce the interplanar spacing. The change of V valence during the charge–discharge process of Na 2.8 Li 0.2 V 2 (PO 4 ) 3 /C is consistent with that of NVP by V element XANES characterization. There is no conventional phase transition phenomenon in the ex-situ XRD high-voltage charging state. The above facts indicate that lithium doping obtains a stable solid solution NVP. The electrochemical test results show that Na 2.8 Li 0.2 V 2 (PO 4 ) 3 /C can provide an amazing reversible capacity of 116.9 mAh/g (theoretical capacity of 117 mAh/g) and capacity retention rate of 99.82 % after 500 cycles. GITT results show that Li + can significantly increase the Na + diffusion coefficient of the material. Such excellent electrochemical performance is attributed to the fact that the doping of Li + activates the activity of Na + in Na (2) site and improves the reaction efficiency.
