Composite polymer electrolytes (CPEs) have attracted wide attention because of their enormous potential to address the limitations of traditional liquid electrolytes. However, the inevitable aggregate and precipitate of inorganic filler in polymer electrolytes could lead low ionic conductivity , poor interfacial compatibility and mechanical property, which limited the application of CPEs for high energy density solid-sate batteries. Herein, a novel composite electrolyte membrane (Z-CPE@ZIF60) was achieved by impregnating ZIF-67 particles into a poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP) and polyacrylonitrile (PAN) hybrid nanofibers membrane with continuous and interconnected 3D network via electrospinning and in situ photopolymerization strategy. Using this electrolyte membrane for quasi-solid-state sodium batteries, a high ionic conductivity of 1.42 × 10 −3 S cm −1 and outstanding Na + transference number of 0.58, and excellent mechanical properties was obtained at room temperature owing to continuous Na + conduction pathways in the interconnected 3D network with PVDF-HFP/PAN hybrid nanofibers, the Lewis acid-base interaction between anions and ZIF-67. In addition, the solid electrolyte interface film formed by the contact of PVDF-HFP and Na anode effectively suppressed the growth of sodium dendrites. As a result, symmetric Na cells exhibit a stable polarization for 600 h under 0.1 mA cm −2 , indicating outstanding Na stripping/plating reversibility. Furthermore, the quasi-solid-state sodium batteries Na 0.67 Ni 0.33 Mn 0.37 Ti 0.3 O 1.9 F 0.1 (NaNMTi 0.3 OF)/Z-CPE@ZIF60/Na displayed impressive rate and cycling performance.

To reconcile the contradiction between piezoelectric property and its temperature stability, the preparation of composite piezoceramics using multiple components has become an emerging direction. Herein, (K,Na)NbO 3 -based piezoceramics are adopted to prepare high-performance laminated composite ceramics inspired by the lamination composite strategy, and sintered in the reducing atmosphere to meet the development of multilayer piezoelectric actuators with base metal internal electrodes. By adjusting the composition ratio, a high inverse piezoelectric coefficient d 33 * of 1065 pm/V (@ 2 kV/mm) is obtained in the two-component composite ceramics, which fluctuated less than ± 6% in the range of 25–160 °C. In the three-component composite ceramics, a higher d 33 * value of 1326 pm/V (@ 2 kV/mm) is achieved and maintained > 90% until 150 °C. The electric-field-induced strain performances of laminated composite ceramics significantly exceed those of their basic components, which is related to the piezoresponse gain provided by the internal interfaces. The excellent temperature stabilities come from the more diffused phase transition temperature range formed by the complementation of multiple components. The combination of ultrahigh strain performance, high temperature stability, and good fatigue resistance, together with sintering in the reducing atmosphere, constitutes an important step to promote the application of (K,Na)NbO 3 -based multilayer piezoelectric actuators.

An air purifier that provides clean air will be popular if it is portable and capable of removing volatile organic chemicals and reducing exposure to bacteria. Herein, ultra-thin and dense Bi 2 WO 6 nanoflakes grown on W meshes specialize in offering abundant oxygen vacancies due to Na + driving laminar splitting. Under visible lights , the photogenerated carriers streaming along the ultrathin Bi 2 WO 6 surface produce bountiful reactive oxygen species for mineralizing VOCs and sweeping bacteria. Enriched with •O 2 - and •OH, a 15 cm*5 cm Na-Bi 2 WO 6 mesh can completely degrade 30 ppm toluene in 0.45 dm 3 reactor in 1 hour without producing any toxic intermediates like benzene, and its efficacy only decayed by 4% after a continuous 14-hour run. A cup-shaped air purifier was assembled with the Na-Bi 2 WO 6 mesh, enabling the rapid elimination of 1 ppm toluene, 2 ppm formaldehyde, and bacteria within a 120 dm 3 test space.

The mixed phosphate Na₄Fe₃(PO₄)₂(P₂O₇) (NFPP) via synergistic coordination of mixed [PO₄]/[P₂O₇] anion groups achieves a flat voltage plateau at 3.2 V (vs. Na + /Na) and a theoretical specific capacity of 129 mAh g −1 , but its practical application is still limited by its inherent low electronic conductivity. Through structural integration of polyanion-type cathode materials, this study innovatively designed and constructed hierarchical Na₄Fe₃(PO₄)₂(P₂O₇)@C mesoporous microspheres (NFPP@CMMS). The NFPP nanocrystals uniformly embedded in a three-dimensional interconnected meso porous carbon matrix (pore size distribution: 2–5 nm). Such hierarchical meso/micro-nano architectures provided expansive ion-exchange interfaces, accelerating Na + de/intercalation kinetics while enhancing electronic conductivity and mitigating structural collapse during cycling. Consequently, the NFPP@CMMS delivers exceptional reversible discharge capacity (121 mAh g −1 at 0.1C), outstanding rate capability (72 mAh g −1 at 50C), and superior cycling stability (90.70 % capacity retention after 3500 cycles at 5C). This triple-synergy strategy—combining nano-confinement effects, interconnected mesoporous channels, and carbon-encapsulated network—provides a novel pathway for developing practical sodium-ion battery cathodes.

Ion doping is an effective strategy for achieving high-performance flexible Cu 2 ZnSn(S,Se) 4 (CZTSSe) solar cells by defect regulations. Here, a Li&Na co-doped strategy is applied to synergistically regulate defects in CZTSSe bulks. The quality absorbers with the uniformly distributed Li and Na elements are obtained using the solution method, where the acetates (LiAc and NaAc) are as additives. The concentration of the harmful Cu Zn anti-site defects is decreased by 8.13% after Li incorporation, and that of the benign Na Zn defects is increased by 36.91% after Na incorporation. Synergistic Li&Na co-doping enhances the carrier concentration and reduces the interfacial defects concentration by one order of magnitude. As a result, the flexible CZTSSe solar cell achieves a power conversion efficiency ( PCE ) of 10.53% with certified 10.12%. Because of the high PCE and the homogeneous property, the Li&Na co-doped device is fabricated to a large area (2.38 cm 2 ) and obtains 9.41% PCE . The co-doping investigation to synergistically regulate defects provides a new perspective for efficient flexible CZTSSe solar cells.

Finding sodium solid electrolytes (SSEs) with good performance is key to building all-solid-state sodium batteries. In the development of solid electrolytes, halogen doping has been shown to be an effective approach. However, it has rarely been applied to chalcogenide-based SSEs, possibly because of strict structure constraints. In this work, the strategy of halogen doping is successfully demonstrated on Na3.67[Sn0.67Si0.33]0.67P0.33S4, a novel SSE with high structural tolerance. The halogen-doped samples formulated as Na3.57[Sn0.67Si0.33]0.67P0.33S3.9X0.1 (X = Cl, Br, and I) exhibit higher ionic conductivities and lower activation energies than the pristine sample. Na3.57[Sn0.67Si0.33]0.67P0.33S3.9I0.1, the I-doped sample, has the highest ambient ionic conductivity of 1.08 mS cm–1 and the lowest activation energy of 0.24 eV. Structure analysis indicates that the high electronegativity of Cl atoms plays an important role in improving the conduction of Na+ ions in Cl-doped samples. The large atomic radius and high polarizability of I are more important factors to accelerate the transportation of Na+ ions in the I-doped counterpart. Furthermore, the all-solid-state sodium batteries assembled with Na3.57[Sn0.67Si0.33]0.67P0.33S3.9I0.1 as solid electrolytes show decent cyclic stability at 30 °C with a current density of 0.15 A g–1. This work systematically manifests the effect of halogen doping in SSEs, providing a versatile method to develop novel SSEs.

The sensitive determination of levoglucosan in aqueous samples has great significance for the study of biomass burning. Although some sensitive high-performance liquid chromatography/mass spectrometry (HPLC/MS) detection methods have been developed for levoglucosan, there are still plenty of shortcomings, such as complicated sample pre-treatment procedures, large-amount sample requirements, and poor reproducibility. Herein, a new method for the determination of levoglucosan in the aqueous sample was developed using ultra-performance liquid chromatography with triple quadrupole mass spectrometry (UPLC-MS/MS). In this method, we firstly found that compared with H+, Na+ could effectively enhance the ionization efficiency of levoglucosan, even though the content of H+ is higher in the environment. Moreover, the precursor ion m/z 185.1 [M + Na]+ could be used as a quantitative ion to sensitively detect levoglucosan in aqueous samples. Only 2 μL of un-pretreated sample is required for one injection in this method, and great linearity was obtained (R2 = 0.9992) using the external standard method when the concentration of levoglucosan was 0.5–50 ng mL−1. The limit of detection (LOD) and quantification (LOQ) were 0.1 ng mL−1 (0.2 pg absolute mass injected) and 0.3 ng mL−1, respectively. Acceptable repeatability, reproducibility, and recovery were achieved. This method has the advantages of high sensitivity, good stability, good reproducibility, and simple operation, which could be widely used for the detection of different concentrations of levoglucosan in various water samples, especially for the detection of samples with low content such as ice core or snow samples.

Thermal stability holds particular significance for phosphors intended for LEDs . Abnormal thermal quenching was successfully reached by strategic point defect engineering by inserting Frenkel defects and nonequivalent substitution defects in novel Sm 3+ ions doped Na-rich distorted double perovskite Na 1.5 La 1.5 TeO 6 phosphors. Its integral intensity at 420 K (115.03 %) was far higher than that of room temperature . Besides, the phosphors exhibited a pronounced orange-red emission peak at 644 nm when excited at 404 nm, which was ascribed to the 4 G 5/2 - 6 H 9/2 transition of Sm 3+ ions. The concentration quenching phenomenon resulting from dipole-dipole interactions was observed in the phosphors, and the optimal concentration of dopant Sm 3+ was determined to be 1 mol%. After calculation, it was surprising that the color purity values of all phosphors were not less than 99.9 %. Additionally, the internal quantum efficiency (IQE) reached 65.30 %, and the activation energy ( E a ) of Na 1.5 La 1.5 TeO 6 :1 mol%Sm 3+ was 0.570 eV. Meanwhile, the emission spectrum of the produced orange-red light emitting diodes (LEDs) exhibited a close correspondence with the absorption curves of various plant pigments (chlorophyll b , allophycocyanin, phycocyanin, phytochrome red and far red (P R and P FR )). The prepared white light emitting diodes (WLEDs) possessed low correlated color temperature (CCT) of 4769 K and as high general color rendering index (CRI, R a ) value as 91. In summary, the phosphors presented promising options for plant-cultivating LEDs and high CRI WLEDs based on their superior optical and thermal properties .

Rechargeable Na-CO 2 batteries are considered to be an effective way to address the energy crisis and greenhouse effect due to their dual functions of CO 2 fixation/utilization and energy storage. However, the insolubility and irreversibility of solid discharge products lead to poor discharge capacity and poor cycle performance. Herein, a novel strategy is proposed to enhance the electrochemical performance of hybrid Na-CO 2 batteries, using water-in-salt electrolyte (WiSE) to establish an optimal reaction environment, regulate the CO 2 reduction pathway, and ultimately convert the discharge product of the battery from Na 2 CO 3 to formic acid (HCOOH). This strategy effectively resolves the issue of poor reversibility, allowing the battery to exhibit excellent cycle performance (over 1200 cycles at 30 °C), especially under low-temperature conditions (2534 cycles at −20 °C). Furthermore, density functional theory (DFT) calculations and experiments indicate that by adjusting the relative concentration of H/O atoms at the electrolyte/catalyst interface, the CO 2 reduction pathway in the battery can be regulated, thus effectively enhancing CO 2 capture capability and consequently achieving an ultra-high discharge specific capacity of 148.1 mAh cm −2 . This work effectively promotes the practical application of hybrid Na-CO 2 batteries and shall provide a guidance for converting CO 2 into products with high-value-added chemicals.

Functionalized monomers are of utmost importance in producing new polymers and smart materials. Herein, a two-step approach involving heterogeneous catalysis was developed to produce a functionalized monomer (2-vinylfuran) from bio-based furfural, giving an overall yield of 89%. Economic analysis suggests that this facile approach incurs much lower costs, and its practicality improves the availability of 2-vinylfuran. This is due to the delicate structure of the optimized 4Na5Ce/SiO2, where Na species are present at the oxygen vacancies of the ceria that protect the catalyst structure from collapse, and the catalyst consequently displays excellent performance. Density functional theory (DFT) calculations revealed that the reaction occurs on the Na and Ce species. The adsorption of a furan group onto Na led to side reactions, which were suppressed in the presence of Ce, resulting in higher selectivity. Finally, a polymer based on 2-vinylfuran was prepared, which shows good surface properties and thermodynamic stability.

The development of thin sodium (Na) metal anodes (e.g., ≤ 40 μm) with favorable electrochemical performance is crucial for the practical implementation of high energy density batteries. However, producing such thin Na foils remains challenging because of metallic Na’s poor processability under conventional mechanical rolling techniques. This study reports the successful fabrication of free-standing Na/Na 2 In (NaIn61) composite foils with tunable thicknesses from 40 to 20 μm. They were successfully fabricated via repeated mechanical rolling, using metallic Na and indium as precursors. In-situ generated Na 2 In particles were uniformly distributed within the Na matrix, and strong interfacial bonding between Na 2 In and Na effectively suppressed dislocation motion during extrusion, thereby significantly enhancing the mechanical processability of the composite foil. Furthermore, Na 2 In reduced the nucleation barrier for Na deposition and stabilized the solid electrolyte interphase, improving Na plating/stripping behavior. A full-cell assembled with a 40 μm-thick NaIn61 composite anode and a NaFe 1/3 Ni 1/3 Mn 1/3 O 2 cathode achieved a high energy density of approximately 172 Wh kg -1 at 0.2 C with a low negative-to-positive capacity ratio of ∼2.0. These findings demonstrate the effectiveness of rational composite design in enabling the production of free-standing, thin Na metal anodes with improved electrochemical performance.

Background Patients with locally advanced head and neck squamous cell carcinoma (HNSCC) exhibit poor survival due to tumor microenvironment (TME) barriers and systemic toxicity of chemo-immunotherapy associated with chemo-immunotherapy. Methods An injectable thermoresponsive hydrogel was engineered by crosslinking D-α-tocopheryl polyethylene glycol succinate (TPGS) with Na₂CO₃ (15 % w/v TPGS: 9 % w/v Na₂CO₃). This platform co-encapsulated doxorubicin-loaded nanoparticles (DOX NP) synthesized via PEI-cis-aconitic acid conjugation and CpG-loaded adjuvant nanoparticles (CpG NP) prepared through genipin-mediated PEI crosslinking. The hydrogel exhibited rapid temperature-triggered gelation, shear-thinning injectability, and a macroporous architecture that enabled dual drug retention and immune cell infiltration. Results In vitro , the hydrogel provided the sustained release of DOX NP with pH-responsive acceleration in acidic TME. In vivo , localized delivery of Gel-DOX NP-CpG NP significantly suppressed tumor growth ( p < 0.05) and enhanced cytotoxic CD8 + T-cell infiltration in TME (3.1-fold) and spleens (2.4-fold). RNA sequencing revealed 88 immune-related differentially expressed genes, including downregulated immunosuppressors and enriched cytokine pathways. Conclusion This TPGS/Na₂CO₃ hydrogel platform coordinates chemotherapy-induced immunogenic cell death (DOX NP) with CpG-driven innate immunity, overcoming TME barriers to enhance localized and systemic anti-tumor responses in HNSCC.
