A B S T R A C T Headings ethnopharmacological relevance Sangbaipi Decoction (SBPD) is an effective treatment for lung diseases caused by phlegm-heat obstruction according to Jingyue Quanshu , and soothes panting by purging the lung meridian. It is composed of anti-pyretic herbs (e.g., Scutellaria baicalensis Georgi and Coptis chinensis Franch.) and antitussive herbs (e.g., Cortex Mori and Armeniacae Semen Amarum ). Therefore, we hypothesized that SBPD has therapeutic effects on lung injury caused by influenza virus. Aim of the study This study aimed to explore anti-influenza activity, active components, and mechanisms of SBPD. Materials and methods The anti-influenza activities of SBPD were determined in 48 h drug-treated MDCK cell model using CPE and plaque reduction assays, and 24 h drug-treated A549 cells using qRT-PCR. The in vivo efficacy of SBPD (1.0g/kg/day and 0.5g/kg/day) was evaluated in PR8 infected BALB/c mice. The chemical component was assessed through HPLC-Q-TOF MS/MS analysis. Network pharmacology was built via TCMSP, GeneCards, DisgeNet, OMIM, DrugBank databases, and Cytoscape software. Additionally, TOA, HI and NAI assays were employed to investigate impact on the virus replication cycle with different concentrations of SBPD (2.5 mg/mL, 1.25 mg/mL, or 0.625 mg/mL). Results In MDCK infected with viruses A/PR/8/34, A/Hong Kong/1/68, or A/California/4/2009, the IC 50 values of SBPD were 0.80 mg/mL, 1.20 mg/mL, and 1.25 mg/mL. In A549 cells, SBPD treatment reduced cytokine expression (e.g., TNF-α, IL-6, IL-1β) ( p < 0.05). In PR8 infected BALB/c mice, SBPD improved the survival rate of infected mice, reduced lung index ( p < 0.05), protected lung tissue from pathological damage, and regulated cytokine overexpression ( p < 0.05). 29 components of SBPD were identified in SBPD treated mouse serum including some phytochemicals targeting influenza proteins. HI and NAI assays suggested the potential antiviral mechanism of SBPD through inhibition of HA and NA. Conclusion This study is the first to demonstrate the anti-influenza and the anti-inflammatory effects of SBPD in vitro and in vivo. Its major anti-influenza phytochemicals were explored and its inhibitory effects on HA and NA protein were proved. It provides more options for anti-influenza drug discovery.

An interlayer-expanded vanadium disulfide (VS 2 ) electrode has been developed to enhance the performance of sodium ion batteries. The interlayer expansion of the (0 0 1) plane from the standard 5.7 Å to 9.5 Å improves capacity by 2–3 times at various current densities even over long cycles. This advancement is credited to the optimized kinetics of Na + diffusion, as the intrinsic structure of VS 2 with weak van der Waals interlayer interactions leads to minimal resistance along 2D ionic diffusion routes. Our findings highlight the significance of interlayer engineering in designing efficient energy storage electrodes.

Separating CO 2 and N 2 from CH 4 is crucial for energy production and environmental protection. This study showed the rapid synthesis of CHA zeolites with different morphologies using an in situ growth method, without the assistance of organic structure directing agents (OSDA) or fluoride media. The crystallization behavior of CHA zeolites was studied in terms of synthesis gel composition (including water content, silicon and aluminum content, alkalinity and Sr 2+ concentration), synthesis temperature and duration. The results suggested that pure phase CHA zeolite nano-aggregates could be synthesized with broad precursor conditions at 150 °C for only 4 h. Then, K-CHA zeolite was ion-exchanged to Na-CHA and Ca-CHA and the adsorption properties of CHA zeolites with different morphologies and ions were studied. The results suggested that Na-CHA exhibited highest CH 4 , CO 2 and N 2 adsorption capacity and showed higher ideal selectivity for N 2 /H 2 ; Although Ca-CHA zeolites exhibited relative lower CO 2 and CH 4 adsorption capacity, it exhibited the highest ideal selectivity for CO 2 /CH 4 ; Simultaneously, K-CHA zeolite exhibited high CH 4 adsorption capacity and high adsorption separation ability of CH 4 /N 2 . Furthermore, breakthrough experiments have confirmed the practical feasibility of separating CO 2 from CH 4 .

Electrochemical mechanical polishing (ECMP), through the introduction of electric field, promotes the chemical reaction during polishing. However, the addition of electric field will accelerate the oxidative corrosion, at this time the effective corrosion inhibitor must be added in the polishing solution. Nevertheless, most traditional corrosion inhibitors are toxic and inhibition efficiency is low. In order to meet this technical challenge, this paper investigates the effect of two green corrosion inhibitors, chitosan oligosaccharide (COS) and carboxymethylcellulose sodium (CMC-Na), on Co ECMP, and compares them with the traditional inhibitor TAZ. The results show that when COS and CMC-Na are added at the same time, the polished Co surface quality can be greatly improved, and the surface roughness decreases by 94.6 %. It indicates that adding COS and CMC-Na simultaneously can play the best corrosion inhibition effect and achieve the best surface quality. The synergistic behavior and action mechanism of COS/CMC-Na are analyzed by polishing experiments, static corrosion, electrochemical tests, XPS, and AFM. This study provides a reference for the development of green polishing solutions for Co ECMP.

Prussian blue analogues (PBAs) have attracted great interests due to their stable and open framework structures as novel electrode materials in rechargeable sodium-ion batteries (SIBs). However, Na + diffusion within electrode materials not only relates to many confined spaces formed by lattice frameworks for Na-ion storage but also highly involves with Na + migration channel generated by lattice periodic arrangement. In this work, the correlation between PBAs crystallinity and Na + insertion/extraction properties were systematically investigated. High-crystallized nickel hexacyanoferrate (NiHCF-h) exhibits a fast Na-ion migration process with a high diffusion coefficient of 8.1 × 10 −10 cm −2 s −2 , and a high capacity retention of 73.7% at 4.25 A g −1 . Even crystal size is six times larger than low-crystallized nickel hexacyanoferrate (NiHCF-l), the high-crystallized NiHCF-h shows a faster Na + insertion/extraction process. The basic structural characterization and pair distribution function (PDF) analysis show that NiHCF-h has a long-range lattice periodicity, enabling Na ions transfer more easily through migration channels. This demonstrates that the crystallinity of PBAs is an extremely important factor in ionic migration process, even with proved vacancies and H 2 O molecules in PBAs framework structure.

Lead-free dielectric ceramic capacitors have attracted substantial attention for high pulsed power technologies, but achieving a large recoverable energy storage density ( W rec ) with high efficiency ( η ) and good thermal stability remains a bottleneck. In this work, we address this challenge in (Bi,Na)TiO 3 -based relaxor ferroelectric through a composition design strategy that induces local structure heterogeneity. This heterogeneity is created from the local random field/stress of the chemical modifiers due to different valence states and ionic sizes, which promotes the formation of polar nano-regions (PNRs). These PNRs minimize the energy barrier, resulting in an excellent energy storage performance, W rec of 8.53 J/cm 3 and η of 80.7 %. Moreover, the material exhibits breakthrough thermal stability, maintaining a W rec ≈ 3.41 ± 0.40 J/cm 3 and η ≈ 82.2 ± 8.2 % over a wide temperature range up to 240 °C. This study provides a path for designing advanced relaxor ferroelectric dielectric ceramic capacitors for energy storage applications.

Among the various types of cathode materials for sodium ion batteries , NaFePO 4 attracts much attention owing to its high theoretical capacity (155 mA h g −1 ), low cost, high structural stability, and non-toxicity. Nevertheless, the NaFePO 4 with maricite structure, thermodynamically stable phase, has been considered as electrochemically inactive for sodium-ion storage. In this work, we succeeded in tuning the degree of disorder in NaFePO 4 cathode material by a mechanochemical route to enhance electrochemical performances of Na-ion batteries. The derived NaFePO 4 cathodes containing both amorphous and maricite phases exhibit much improved sodium storage performance with an initial capacity of 115 mA h g −1 at 1 C and an excellent cycling stability of capacity retention of 91.3% after 800 cycles. By X-ray absorption near edge and Raman spectroscopy , we revealed the atom-scale structural origin of the enhanced Na-storage performances of the amorphous NaFePO 4 electrode. The transformation of edge-sharing FeO 6 octahedra into various FeO n polyhedra upon amorphization was found to be a key to attain the superior performances for Na ion batteries.

We report a low-cost hydrogel electrolyte by adding 3 wt% poly(acrylate sodium) (PAAS) into 1 M Na2SO4 aqueous electrolyte, which achieves a widened electrochemical stability window (ESW) of 2.45 V on stainless steel current collector from 2.12 V in 1 M Na2SO4 aqueous electrolytes (AE). Moreover, the H2 evolution potential reaches −1.75 V vs. Ag/AgCl on titanium current collector. The results reveal that the polymer network structure of PAAS has the ability to interact with water molecules and thus the hydrogen evolution reaction can be limited effectively, which broadens the ESW of aqueous electrolyte and allows the reversible Na-ion intercalation/deintercalation of Na3V2(PO4)3 as an anode material in aqueous electrolyte reported for the first time.

Compositional fluctuation of the K and Na elements during the preparation process becomes a major issue for (K,Na)NbO 3 (KNN) lead-free ceramics to maintain relatively stable electrical properties. The raw material Bi 2 O 3 is more sensitive to high temperature. To improve electrical properties, it is more necessary to compensate the volatile Bi. In this work, the 0.96K 0.48 Na 0.52 Nb 0.96 Sb 0.04 O 3 -0.04Bi 0.5*(1+ x ) Na 0.5 ZrO 3 ( x = −0.05, −0.02, 0.00, 0.02, 0.05, and 0.08) ceramics were selected as basis material. The excess Bi can increase the phase fraction of the T phase and decrease oxygen vacancy content, which effectively enhance the extrinsic contribution of the piezoelectric response. The electromechanical properties were optimized by excess Bi, and the optimal properties ( d 33 = 522 pC/N, k p = 58.9%, T c = 235 °C) were obtained in the ceramic with x = 0.05. The present work provides new guidelines for enhancing the piezoelectric performance of KNN ceramics by a simple method, which can be applied to other lead-free piezoelectric ceramic systems.

The practical application of P2-type sodium cathodes is restricted by intrinsic Na + /vacancy ordering and unstable cathode-electrolyte interphases (CEI). While conventional inactive-element doping improves stability, it typically sacrifices specific capacity. Addressing these challenges, we demonstrate that trace Bi doping simultaneously boosts specific capacity, cycling life, and rate performance, effectively circumventing the classic capacity-stability trade-off. The concurrent improvement primarily originates from Bi-induced structural modulation, which we quantitatively characterize through a newly proposed oxygen-ion displacement rate ( δ O ) descriptor. Through doping control, we successfully synthesized two P2-type materials with significantly distinct δ O values (∼38.07 % vs. ∼31.58 %), demonstrating the critical role of δ O in governing electrochemical performance. The material with ultra-low δ O has suppressed Na + /vacancy ordering due to its weak Na-O correlations. Additionally, its strong TM-O correlations effectively inhibit TM (transition metals) dissolution, construct a stable CEI, and alleviate the lattice strain. Consequently, this material exhibits delivers a 23.1 % enhancement in specific capacity, exceptional cycling stability (72.9 % capacity retention after 1000 cycles), and remarkable rate performance by achieving a 51.1 % capacity within just 34 s. This work introduces a pioneering perspective based on oxygen-ion displacement for designing high-performance oxide cathode materials.

Aqueous Na-ion batteries (ANIBs) are promising candidates for grid-scale energy storage owing to their inherent safety, low cost, and rapid ion transport kinetics. While current research focuses on enhancing capacity and kinetics to overcome energy density limitations and leverage their inherent kinetic advantages under extreme conditions such as high mass loading and low temperatures, investigations remain predominantly centered on electrode materials and electrolytes, with binders being notably understudied. Here, we investigate the impact of two prevalent binders-polyvinylidene difluoride (PVDF) and polytetrafluoroethylene (PTFE)-on the electrochemical performance of nickel hexacyanoferrate (NiHCF) electrodes in ANIBs. Our results reveal that PVDF's better adhesion and electrolyte wettability optimize ion transport, significantly enhancing electrode kinetics vs. PTFE. Utilizing PVDF as the binder in a 3D-printing platform, we fabricated a freestanding electrode achieving >20 mg cm−2 active material loading, superior kinetics, and >95% capacity retention over 4000 cycles. The derived full cell reduces polarization at −20 °C, delivering higher energy density than PTFE-based full cells. This work demonstrates a multiscale regulation strategy for binder-electrode structures, offering a viable pathway toward high-performance aqueous energy storage systems.

Metal phosphorus trichalcogenides (MPTCs) have demonstrated remarkable advantages as anode materials for alkali metal ion batteries because of their unique electronic structure and layered characteristics. In this study, layered CdPS 3 was successfully prepared by chemical vapor transport, and its Na + storage performance and reaction mechanisms were systematically investigated. Electrochemical tests revealed that CdPS 3 maintains a reversible capacity of 195.7 mA h g −1 after 340 cycles at a high current density of 5 A g −1 , revealing exceptional cyclic stability. Comprehensive characterization confirmed that the sodium storage process follows a typical multi-stage mechanism encompassing intercalation, conversion, and alloying (mainly during the first 40 cycles) processes, wherein partial conversion of CdPS 3 generates electrochemically active CdS nanoparticles that participate in subsequent electrochemical processes. Kinetic analysis indicated high Na + diffusion coefficients in CdPS 3 , while theoretical calculations revealed preferential Na + adsorption within the CdPS 3 interlayers. These findings provide important theoretical and experimental foundations for developing high-performance metal phosphorus trichalcogenides anode materials.
