Osteoporotic bone defects are challenging to repair due to imbalances in bone resorption and formation, coupled with insufficient vascularization. To address these issues, it develops a trifunctional hydrogel (SF-ZIF@NA) designed to selectively inhibit osteoclast activity and enhance vascularized bone regeneration. By enzymatically removing sialic acid, SF-ZIF@NA prevents precursor osteoclasts (pOCs) from fusing into bone-resorbing mature osteoclasts (mOCs), thereby preserving pOCs and their anabolic functions. Additionally, the hydrogel releases Zinc ion (Zn 2 ⁺) in response to acidic conditions, promoting osteogenesis and angiogenesis. In vitro results confirmed that SF-ZIF@NA impedes osteoclast fusion, enhances platelet-derived growth factor-BB (PDGF-BB secretion from pOCs, and activates the FAK (focal adhesion kinase) signaling pathway to stimulate vascularized bone formation. In osteoporotic bone defect models, SF-ZIF@NA accelerated bone repair with increased bone density and vascularization. These findings demonstrate that SF-ZIF@NA offers a targeted and multifunctional strategy for osteoporotic bone regeneration by concurrently modulating osteoclast activity and promoting angiogenesis.

The Na metal anode has long been considered as one of the most promising anode types due to its high theoretical capacity and its having the lowest electrochemical potential. Safety concerns, low efficiency, and large volume changes are severe hurdles blocking its practical application, however, especially in the case of high areal capacity. Herein, an oxygen-doped carbon nanotube framework (a-CNTs) obtained after acidification has been adopted as the Na plating matrix to regulate the homogeneous nucleation of Na metal and suppress dendrite growth. The oxygenic functional groups on the carbon nanotubes induce them “sodiophilic”, which guides the homogeneous nucleation and uniform deposition of Na. In addition, the cross-conductive network and high specific surface area of a-CNTs further enhance the electrochemical performances. As a result, a-CNTs have enabled reversible plating/stripping for 1000 cycles with coulombic efficiency of 99.8% at 3 mA cm −2 for 1 mA h cm −2 . Furthermore, the symmetrical cells could run stably for 1650 cycles at 3 mA cm −2 for 1 mA h cm −2 , and even could run for more than 300 h at 5 mA cm −2 at 8 mA h cm −2 , which has rarely been achieved under such aggressive working conditions.

The poor electronic conductivity of Na2FeSiO4 always limits its electrochemical reactivities and no effective solution has been found to date. Herein, the novel Ni-substituted Na2Fe1–xNixSiO4@C nanospheres (50–100 nm) encapsulated with a 3D hierarchical porous skeleton (named as alveolation-like configuration) constructed using in situ carbon are first synthesized via a facile sol–gel method, and the effects of Ni substitution combined with the design of a unique carbon network on Na-storage properties are assessed systematically, focusing on alleviating the inherent defects of the Na2FeSiO4 cathode material. A series of characterization technologies such as X-ray diffraction, transmission electron microscopy, X-ray photoelectron spectroscopy and so forth, coupled with the electrochemical measurements and first-principles calculations, are used to explore the structure, morphology and electrochemical behaviors of the as-prepared materials. The results show that the synergism between Ni substitution and the special alveolation-like configuration enables fast Na ions mobility (from 10–14 to 10–12 cm2 s–1), reduces band gap energy (from 2.82 to 1.79 eV) and lowers Na-ion diffusion barriers, finally reciprocating the vigorous electrochemical kinetics of the electrode. Especially, the elaborately designed material—Na2Fe0.97Ni0.03SiO4@C—displays superior Na-storage properties of around 197.51 mA h g–1 (corresponding to 1.43 Na+ intercalation) at 0.1 C within 1.5–4.5 V along with desirable capacity retention (84.44% after 100 cycles), and the rate capability is also markedly enhanced (a capacity of 133.62 mA h g–1 at 2 C). Such the effective methodology employed in this work opens a potential pathway to synthesize the silicate cathode material with excellent electrochemical properties.

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 .

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.

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.

High-performance cathodes are required for advancing sodium-ion batteries, where both the Na content and transition metal (TM) composition significantly influence electrochemical performance. This work presents a rational design strategy for P2-type layered oxides, integrating increased Na content, reduced Ni/Fe concentration, balanced Mn3+/Mn4+ ratio, and Li incorporation. Guided by this approach, a series of high-Na-content P2-type cathodes was developed, and the key phase formation principles for Fe-containing compositions were revealed. Correlation analysis suggested an optimal composition, Na0.8Li0.07Fe0.12Ni0.11Mn0.7O2, featuring ultralow Ni content, demonstrated enhanced structural stability and Na+ diffusion kinetics. In situ XRD analysis confirmed exceptional structural resilience during cycling, exhibiting minimal lattice strain (1.5% volume variation) attributed to sufficient Na at the Naf site, mitigating TM layer gliding. Electrochemical evaluation revealed outstanding performance: a high reversible capacity (125.8 mAh g–1 at 0.1 C, 2.5–4.5 V), excellent cycling stability (81.6% capacity retention after 500 cycles at 1 C), and superior energy density in full cells (268.1 Wh kg–1). It also exhibited remarkable air stability, retaining structural integrity and 96.9% initial capacity after 10 days of air exposure. This design-oriented strategy not only clarifies the intrinsic phase formation rules but also establishes a paradigm for compositionally guided cathode engineering, bridging fundamental understanding and practical material design.

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.
