Graphical Balancing act : Boron-doped Na 3 V 2 (PO 4 ) 3 is synthesized through a facile electrospinning method. NVP@carbon with a balanced content of BCO 2 and BC 2 O exhibits the best sodium storage properties. BC 2 O mainly improves the sodium diffusion and BCO 2 enhances the structural stability. Na 3 V 2 (PO 4 ) 3 (NVP) is a widely studied cathode material for sodium-ion batteries because of its high ionic conductivity and attractive charge/discharge plateau (3.4 V vs. Na/Na + ). However, its poor electronic conductivity and severe volume expansion during sodium storage need to be addressed before its intensive application could be realized. Herein, boron-doped NVP was synthesized through a facile electrospinning method. By adding boric acid into the reaction mixture during electrospinning followed by carbonization, boron could be directly inserted into the carbon matrix, giving rise to B-doped carbon nanofiber wrapped NVP. By tuning the doping amount, the boron-containing configurations could be facilely manipulated, playing different roles in promoting the sodium storage properties of the composite. Based on the calculation results, BC 2 O enhanced sodium diffusion by lowering the energy barrier, while BCO 2 improved the structural stability. Due to these specific functionalities of the configurations, the as-prepared composite with a balanced amount of BC 2 O and BCO 2 demonstrated superior sodium storage capacity of 113 mAh g −1 at 1 C, outstanding long cycling performance of 103 mAh g −1 at 10 C, and retained 91 mAh g −1 after 1500 cycles. This gave rise to a capacity loss of only 0.08‰ per cycle, much better than the undoped counterpart.

Experiments on simultaneous absorption of SO 2 and NO X from sintering flue gas via a composite absorbent NaClO 2 /NaClO were carried out. The effects of various operating parameters such as NaClO 2 concentration ( m s ), NaClO concentration ( m p ), molar ratio of NaClO 2 /NaClO ( M ), solution temperature ( T R ), initial solution pH, gas flow ( V g ) and inlet concentration of SO 2 ( C S ) and NO ( C N ) on the removal efficiencies of SO 2 and NO were discussed. The optimal experimental conditions were determined to be initial solution pH = 6, T R = 55 °C and M = 1.3 under which the average efficiencies of desulfurization and denitrification could reach 99.7% and 90.8%, respectively. Moreover, according to the analysis of reaction products, it was found that adding NaClO to NaClO 2 aqueous solution is favorable for the generation of ClO 2 and Cl 2 which have significant effect on desulfurization and denitrification. Finally, engineering experiments were performed and obtained good results demonstrating that this method is practicable and promising.

Sodium vanadium fluorophosphate, Na 3 (VO 1− x PO 4 ) 2 F 1+2 x (0 ≤ x ≤ 1), is proved to be a series of very promising cathode materials for Na-ion batteries, owing to the high operating voltage and structural stability. However, the selective preparation of phase-pure Na 3 (VO 1− x PO 4 ) 2 F 1+2 x (0 ≤ x ≤ 1) with outstanding electrochemical performance still remains a big challenge. Moreover, there are lots of discrepancies concerning the Na-storage properties, including a diversity of voltage profiles and capacities reported, based on the variety of synthetic methods. Herein, a comprehensive investigation is conducted about the fabrication of phase-pure Na 3 (VO 1− x PO 4 ) 2 F 1+2 x (0 ≤ x ≤ 1) by employing different starting materials and corresponding synthetic conditions, based on a facile low-temperature hydrothermal strategy. Results show that the pH in the reaction system may be of vital importance for the successful preparation of Na 3 (VO 1− x PO 4 ) 2 F 1+2 x (0 ≤ x ≤ 1) with special microarchitecture. Furthermore, it is found that NaH 2 PO 4 ·2H 2 O is the most appropriate phosphorus source, while VCl 3 , VOSO 4 · x H 2 O, and NH 4 VO 3 are the best choices of vanadium sources to prepare Na 3 (VO 1− x PO 4 ) 2 F 1+2 x (0 ≤ x ≤ 1) with superior Na-storage performance. This is the first time that the underlying correlations between the starting materials and the Na-storage performance, are investigated and further that guidance for the selective synthesis of phase-pure Na 3 (VO 1− x PO 4 ) 2 F 1+2 x (0 ≤ x ≤ 1) with superior performance is provided.

Simple SummaryThis study examines the impact of sodium acetate and sodium butyrate supplementation on the compositional profile, blood biochemical parameters, and volatile flavor compounds of lactating mares’ milk. By employing comprehensive analytical techniques, including Gas Chromatography–Ion Mobility Spectrometry (GC-IMS), this study elucidates the effects of these additives on both the chemical composition and sensory attributes of the milk. The findings offer critical insights into optimizing its flavor profile, enhancing overall quality, market appeal, and nutritional value.This study aims to explore the impact of adding sodium acetate and sodium butyrate on the composition, blood biochemical parameters, and volatile flavor compounds of lactating mares’ milk. By assessing the influence of these additives on milk flavor enhancement, the findings provide scientific evidence for optimizing flavor characteristics and offer new strategies for improving the sensory attributes of mare milk products. Eighteen lactating Yili mares were randomly assigned to three groups: a control group, a sodium acetate group (85 mg/kg·BM−1), and a sodium butyrate group (85 mg/kg·BM−1). The experiment lasted 90 days, with milk yield recorded on days 0, 30, 60, and 90. Milk samples were collected on day 60 (peak lactation) for compositional analysis, and GC-IMS was employed to identify and quantify volatile compounds. Additionally, blood samples were drawn from the jugular vein before morning feeding on day 60 using heparinized tubes to assess key biochemical markers, including glucose, triglycerides, total cholesterol, and urea. The results revealed the following findings: (1) Milk yield and composition: The addition of sodium acetate and sodium butyrate had no significant effect on milk yield. However, both treatment groups exhibited significantly or extremely significantly higher milk fat content compared to the control group, whereas milk protein and lactose levels remained largely unchanged. (2) Blood biochemical indicators: The sodium butyrate group showed an extremely significant increase in urea levels compared to the sodium acetate and control groups. Glucose levels in the sodium acetate group were also significantly higher than in the control group. Moreover, triglyceride levels were markedly elevated in the sodium butyrate group compared to the sodium acetate group, while total bilirubin concentrations were significantly higher in the sodium acetate group than in the control group. (3) Volatile compounds: The addition of these additives led to a significant increase in the diversity and concentration of volatile compounds in mare milk. Notably, esters, aldehydes, and ketones showed substantial enrichment in both treatment groups. The relative abundance of esters such as butyl acetate, L-lactic acid ethyl ester, 1-pentene-3-ol, pentanol, and 3-pentanone increased, alongside a significant rise in aldehydes and ketones, including 2-heptenal and 3-pentanone. In conclusion, sodium acetate and sodium butyrate enhance milk flavor by modulating milk composition and metabolic parameters, providing a scientific foundation for improving the quality of mare milk products.

Commercial battery separators (Celgard) have poor wettability, poor heat resistance, and low needle punching strength, and the growth of sodium dendrites can easily pierce the separators, seriously threatening the life and safety of room-temperature sodium-sulfur batteries (RT Na-S). In this work, Polyimide copolymerized with polyether (PI-PEO) membrane was prepared by an electrospinning method. By introducing polyether segments into the polyimide molecular chain and constructing a nanofiber structure, the polarity and fiber structure of the material improved the wettability of the electrolyte, and the toughness of the membrane was improved while ensuring the size stability of the membrane and further resisted the puncture of sodium dendrites. As a result, the battery assembled with the PI-PEO separator exhibits excellent cycle stability. The capacity remains 450 mAh g−1 after 2000 cycles at 3 A g-1. At the same time, the PI-PEO shows a higher ionic conductivity (1.48 mS cm-1), better size stability and electrolyte wettability than Celgard. This work provides a novel and effective method for developing durable room temperature sodium-sulfur batteries.

Sodium superionic conductor NaTi 2 (PO 4 ) 3 has attracted significant interest as an anode material for sodium-ion batteries (SIBs). However, its practical application is hindered by its low inherent electrical conductivity, particularly at low temperatures. In this study, oxygen vacancies (V O ) were introduced into NaTi 2 (PO 4 ) 3 nanoribbons to enhance sodium storage performance at low temperatures. X-ray diffraction with Rietveld refinement, electron paramagnetic resonance, and X-ray photoelectron spectroscopy confirm that NaTi 2 (PO 4 ) 3 -2 nanoribbons (NTP-2) exhibit the richest V O concentration. These V O , which bridge TiO 6 octahedra and PO 4 tetrahedra, significantly enhance the antibonding interactions of Ti1–O2 and P1–O1 bonds, while stabilizing the bonding in NaTi 2 (PO 4 ) 3 . The energy barrier for Na + migration is reduced to 0.40 eV involving the V O . The optimized NTP-2 anode demonstrates superior low-temperature performance, maintaining a capacity of 106.1 mAh g −1 (about 96.1 % of its initial capacity) at −20 °C after 300 cycles. Additionally, the NTP-2 anode exhibits a moderate Na + diffusion coefficient of 1.47 × 10 –11 cm 2 s −1 at −20 °C. Furthermore, the Na 3 V 2 (PO 4 ) 3 //NTP-2 full cell retains a capacity of 64 mAh g −1 at −20 °C after 250 cycles, highlighting its potential for low-temperature applications. By integrating oxygen vacancies and nanoengineering, both electronic and ionic conductivities are significantly enhanced in NaTi 2 (PO 4 ) 3 , positioning promising applications for SIBs in low-temperature environments.

The thermal washing of oily sludge using sodium persulfate (SD) assisted by sodium lignosulfonate surfactant has been demonstrated to be an effective method for oily sludge remediation. To further explore the underlying mechanisms of this process, a systematic study was conducted by simulating oily sludge systems consisting of saturated hydrocarbons (SaH), aromatics hydrocarbons (ArH), resins (Res), and asphaltenes (Asp). The effects of reaction conditions, such as pH, sodium lignosulfonate alkyl (LSA) concentration, SD concentration, and washing temperature, were analyzed. Furthermore, the oxidative kinetic mechanism during the reaction process was investigated. The results demonstrated that neither petroleum hydrocarbons nor SD underwent significant chemical transformations when exposed to LSA, while SD exhibited a marked oxidative degradation effect on all four types of hydrocarbons. Oxidation kinetics indicated that sodium hydroxide played a catalytic role, with SD being the main oxidant and particularly efficient in degrading Asp and Res. Meanwhile, LSA contributed to the removal of hydrocarbons by reducing the surface tension of the solution, enhancing solubilization. This study not only elucidates the central role of SD in the thermal washing process but also provides a solid theoretical foundation for the practical application of this technology in oily sludge treatment.

Most Li+/Na+-conducting solid electrolytes are unstable in moisture, and the formed hydroxides and carbonates on their surfaces result in the increase of the interfacial resistance between solid electrolytes and alkali metal anodes. In this study, heat treatment was used to remove the byproduct coating on the surface of Na3Zr2Si2PO12 (NZSP) that also leads to the generation of Na-ion deficient surface simultaneously. This surface chemistry approach was used to reduce the interfacial resistance and suppress Na-dendrite growth during Na plating. A combination of the metallic Na wetting test, density functional theory, and electrochemical measurement was employed to investigate the origins of ultralow interfacial resistance and mechanism between the Na-ion deficient surface and the metallic Na anode. The analysis demonstrates that the Na-ion-deficient surface effectively improves the contact between NZSP and the metallic Na anode. Moreover, an ultrathin passivating layer involving Na2O was formed between NZSP with metallic Na that protected the NZSP electrolyte from the reduction by metallic Na. This study not only motivates the need for further understanding of the surface chemistry of NZSP but also provides guidelines for the future design of the Na-ion solid–electrolyte interface.

Because of the plentiful supply of sodium, sodium ion batteries (SIBs) as one of the most promising technologies for affordable rechargeable batteries. Here, we outline an easy method for creating a NaFePO 4 @C hybrid composite cathode for SIBs. GCD, CV, and EIS tests have been conducted to study the samples’ electrochemical and kinematic properties. It is confirmed that modest carbon doping can enhance the electrocatalytic activity of NaFePO 4 (NFP). The resulting NFP@C nanocomposite as cathode material for SIBs displays good rate capability and lofty capacity (158.5 mAhg −1 ) retention after 50 cycles at 0.1C. The NaFePO 4 and the carbon covering, which make it easier for the Na + ion and electron to access the material quickly during the process of charging and discharging, respectively, are responsible for the good electrochemical performances. This work highlights the value of investigating novel structures and offers a technique for the creation of NaFePO 4 @C-based cathodes.

The yield of squid has grown gradually; however, the lack of intensive processing has led to the slow development of the squid industry. In a previous study, some organic salts were found to improve the quality of squid surimi gel. Therefore, this research focused on the effects of sodium citrate (SC) and sodium tartrate (ST) on the quality of squid surimi gel. Physical measurements, such as gel texture, water-holding capacity, and color of squid surimi gel, were conducted. The addition of 2.5% SC and ST significantly improved the gel strength by 40.7, 57.0, 22.9, and 58.1%, respectively, of gel strength compared with the addition of: 1.5 SC, 3.5 SC, 1.5 ST, and 3.5% ST alone. Rheological measurements revealed that the addition of 2.5% SC or ST shortened the gel degradation temperature range (i.e., 2.5% SC or ST: 40–53°C; other treatments: 40–60°C) of the squid paste during heating. Results of chemical force analysis showed that the addition of a high quantity of salt accelerated protein aggregation and reduced hydrophobic interactions and disulfide bond formation. Finally, an increase in the number of β-sheets and a decrease in the bulk water content demonstrated that the addition of 2.5% organic salt could form squid gel with a better network structure. The findings provide a scientific basis for the development of high-quality squid surimi gel.
