Manganese-based halides like Li 2 MnCl 4 are attractive for their cost-effectiveness and inverse spinel structure with ion channels. Their use as solid-state electrolytes is limited by low ionic conductivity at room-temperature and poor stability at the lithium interface. Current strategies focus on single-cation doping, which often offers limited conductivity improvements or causes side effects. This study proposes a dual-site cation-anion co-doping strategy to modify lattice defects and Li + migration pathways, thereby enhancing interfacial stability with metallic lithium. Lattice distortion is greatly induced, and Li + vacancy concentration is optimized in Li 1.7 Al 0.1 MnCl 4- x F x ( x = 0–0.7) by substituting Al 3+ at octahedral sites and partially replacing Cl − with F − . Structural and electrochemical tests show that moderate co-doping maintains the cubic structure and greatly improves Li + transport. The best Li 1.7 Al 0.1 MnCl 3.9 F 0.1 exhibits a room-temperature ionic conductivity of 5.2 × 10 −5 S cm −1 , nearly ten times higher than pristine Li 2 MnCl 4 , with a reduced activation energy of 0.45 eV. The distribution of relaxation time analysis further reveals that interface-related relaxation processes remain relatively stable over long time scales. Stable lithium stripping/deposition was demonstrated for hundreds of hours at 0.1 mA cm −2 in lithium-symmetric batteries. However, polarization during long cycling indicates challenges with interfacial stability. This work underscores the impact of dual-site co-doping in developing low-cost, high-performance manganese-based halide solid-state electrolytes.

Semiconductor wastewater containing pollutants such as fluoride ions (F − ), per- and polyfluoroalkyl substances (PFAS) and heavy metals has become an increasingly severe issue. Coagulation is a conventional technique for treating semiconductor wastewater. However, existing coagulants face challenges in efficiently removing PFAS, along with issues such as high metal residues, poor settleability and low floc strength. Inspired by the insect-trapping mechanism of Drosera , we synthesized two silane-modified metal-based coagulants, with significantly enhanced performance. Among them, the Drosera -inspired zirconium-based coagulant (DZHC) outperformed the Drosera -inspired aluminum-based coagulant (DAHC) in terms of F − and PFAS removal efficiency, metal residue, settleability, floc size, Zeta potential and floc strength. Mechanistic analyses revealed that F − removal by DZHC occurs via ligand exchange between Zr-OH and F − , whereas DAHC requires initial Al F complexation followed by hydrolysis-polymerization to form coprecipitates. Additional mechanisms including electrostatic interactions, hydrogen bonding and polycondensation also contribute to defluoridation. The removal of copper citrate primarily relies on ligand exchange between metal hydroxyl groups and [Cu-citrate] − , assisted by electrostatic attraction from quaternary ammonium groups. Molecular dynamics simulations and density functional theory (DFT) calculations demonstrated that hydrophobic interactions from C18 chains on the coagulants dominate PFAS removal. In summary, this study provides a novel strategy for simplifying semiconductor wastewater treatment.

The T-2 and HT-2 toxins, the main metabolites of Fusarium poae , induce toxicity in broilers and accumulate in tissues. Consequently, during the breeding process of broilers, diets are frequently supplemented with physical adsorbents to protect birds against the toxicity induced by mycotoxins. In the present research, T-2 and HT-2 were produced in maize inoculated with F. poae . Mont, the strongest adsorbent based on in vitro adsorption ratios, was added to the contaminated diet. One-day-old chickens were randomly and equally divided into the following four groups: control diet group, Mont supplemented diet group, contaminated diet group and detoxification diet group. The experiment lasted for 42 days. Compared to the control group, the contaminated group showed significant decrease in body weight, feed intake and TP ( P < 0.05), and marked increase in FCR, ALP, AST and ALT activity, T-2/HT-2 residues in the tissues and the relative expressions of apoptosis-related mRNAs ( P < 0.05). Mont supplementation provided protection for the treated broilers in terms of performance, blood biochemistry, hepatic function, T-2/HT-2 residue of tissues and apoptosis. Therefore, Mont may be suitable as a detoxification agent for T-2/HT-2 in feed for broilers.

Heteroatom-doped hollow carbon nanostructures are one of the most promising sulfur hosts for high-performance lithium-sulfur (Li-S) batteries. However, finding a facile and controllable synthesis and enhancing their immobilization effect on polysulfides have been challenging. Herein, we propose a one-step in-situ reaction approach to synthesize N/F dual-doped hollow micro/mesoporous carbon nanospheres (NFHCs) as multifunctional sulfur host, which integrates the physical confinement of hollow porous structure and chemical adsorption/catalytic ability of N/F active sites to realize strong anchoring and accelerated conversion of polysulfides. This sulfur cathode based on NFHCs host with a high sulfur content of 80 wt% enables a superior high-rate capacity of 689 mAh g −1 at 3C, accompanied by outstanding cycle life over 500 cycles at 2C with a capacity decay of only 0.05% per cycle and nearly 100% Coulombic efficiency. This work opens up new horizons to design nanostructured functional hollow carbons for advanced Li-S batteries.

Background Tripterygium wilfordii Hook. f. ( T. wilfordii ) is an important medicinal plant with anti-inflammatory, immunosuppressive and anti-tumor activities. The main bioactive ingredients are diterpenoids and triterpenoids, such as triptolide, triptophenolide and celastrol. However, the production of terpenoids from original plants, hairy roots and dedifferentiated cells (DDCs) are not satisfactory for clinical applications. To find a new way to further improve the production of terpenoids, we established a new culture system of cambial meristematic cells (CMCs) with stem cell-like properties, which had strong vigor and high efficiency to produce large amounts of terpenoids of T. wilfordii . Results CMCs of T. wilfordii were isolated and cultured for the first time. CMCs were characterized consistent with stem cell identities based on their physiological and molecular analysis, including morphology of CMCs, hypersensitivity to zeocin, thin cell wall and orthogonal partial least square-discriminant analysis, combination of transcriptional data analysis. After induction with methyl jasmonate (MJ), the maximal production of triptolide, celastrol and triptophenolide in CMCs was 312%, 400% and 327% higher than that of control group, respectively. As for medium, MJ-induced CMCs secreted 231% triptolide and 130% triptophenolide at the maximum level into medium higher than that of control group. Maximal celastrol production of induced CMCs medium was 48% lower than that of control group. Long-term induction significantly enhanced the production of terpenoids both in cells and medium. The reason for increasing the yield of terpenoids was that expression levels of 1 - deoxy - d - xylulose - 5 - phosphate synthase ( DXS ), 1 - deoxy - d - xylulose - 5 - phosphate reductoisomerase ( DXR ) and hydroxymethylglutaryl - CoA synthase ( HMGS ) were upregulated in CMCs after induction. Conclusions For the first time, CMCs of T. wilfordii were isolated, cultured, characterized and applied. Considering the significant enrichment of terpenoids in CMCs of T. wilfordii , CMCs could provide an efficient and controllable platform for sustainable production of terpenoids, which can be a better choice than DDCs.

Synthesis of moderate–sized uniform spherical covalent organic frameworks (COFs) within 10–50 μm is crucial for their applications in separation fields, while the spherical 2D COFs with such particle sizes has not been reported till now. Herein, a type of moderate–sized spherical 2D COF (TFB–BD COF) with uniform size within 10–50 μm was size–controllably synthesized via an ‘emulsion polymerization–crystallization’ strategy. The obtained TFB–BD COF showed monodisperse full–spherical morphology, good crystal structure and uniform controllable particle sizes. Moreover, another spherical 2D COF (TAPT–PDA COF) with particle size of 15 μm was also synthesized through a similar method for investigating the application potential of the spherical 2D COFs. As an application case, the spherical TAPT–PDA COF was used as the adsorbent for the disperse solid–phase extraction (d–SPE) of bisphenol F (BPF). The adsorbent showed good adsorption selectivity, high adsorption capacity, fast binding kinetics, good reusability (at least four cycles) and high enrichment factor (60 folds). By combining this d–SPE technique with high–performance liquid chromatography, a new analytical method was established for determination of trace BPF in water samples and an orange juice with recoveries of 94.8–101.6% and LOD of 0.56 ng/mL. The synthesis strategy proposed in this work opens a way for size–controllably synthesizing moderate–sized spherical 2D COFs, and the developed analytical method provides a viable path for detecting trace BPF in water samples and beverages.

Two new chromogenic sensors 1-(2-hydroxyphenyl)-3-(4-nitrophenyl)thiourea 1 and 1-(3-hydroxypyridin-2-yl)-3-(4-nitrophenyl)thiourea 2 bearing nitrophenyl and thiourea groups were designed and synthesized by one-step procedure and characterized through 1H NMR, 13C NMR, FTIR, and MS. The anion recognition property of the receptors was studied via naked-eye detection, UV–vis, and 1H NMR. Based on the existence of amino gen and hydroxyl moieties in receptors, receptors 1 and 2 exhibit obvious selectivity by the redshift of UV–vis signals, colour changes through naked-eye detection, and binding effects for F–, H2PO4–, and Ac–. Surprisingly, the detection limits of receptor 1 for F– and Ac– were calculated to be 5.45 × 10−7 and 2.11 × 10−7 (mol/L)−1, respectively, which indicated that F– and Ac– can be identified with high sensitivity by receptor 1. Besides, simple “test strips” were developed and were used as sensors for recognition of F–, H2PO4–, or Ac– in DMSO solution. Lastly, the mechanisms of the recognition process were studied through DFT calculation and 1H NMR titration.

Expanding the family of f-element bearing molybdate iodates via hydrothermal reactions has yielded ten new rare-earth molybdate iodates with two distinct phases, Ln(MoO2)(IO3)4(OH) (LnMoIO-1, Ln = Ce and Pr) and Ln(Mo2O7)(IO3)(H2O)2 (LnMoIO-2, Ln = Gd–Yb, and Y), as well as the first thorium molybdate iodate, ThF(MO4)(IO3) (ThFMoIO). All three structures exhibit three dimensional frameworks and are exclusively built from lanthanide/actinide polyhedra bridged by molybdates and iodates. Furthermore, the coordination versatility of molybdates (octahedral, square pyramidal, and tetrahedral geometries) results in a diversity of structures. The effect of the lanthanide contraction on the compositions and structures is clearly observed, showing the increase in hydration from the early to late lanthanide analogues and the decrease in unit cell dimensions and the average Ln–O bonding distances across the same structure type. Single crystal X-ray diffraction studies reveal that LnMoIO-1 (Ln = Ce and Pr) crystalize in a noncentrosymmetric space group P21 and the second-harmonic generation (SHG) measurement shows a response of 5 × KDP for PrMoIO-1. In addition, CeMoIO-1 crystallizes as orange coloured tablets which are semiconducting in nature with a band gap of 2.41 eV.

The electrochemical properties of vanadium-based materials as cathode materials for aqueous zinc ion batteries are still restricted by low conductivity, sluggish reaction kinetics, and poor structural stability. Herein, the [VO 6 ] octahedron, as the basic unit of vanadium-oxide layer of ammonium vanadates (NH 4 V 4 O 10 , denoted as NVO), is incorporated by F atoms to regulate the coordinated environment of vanadium. Density functional theory (DFT) calculations and experimental results show that both physicochemical and electrochemical properties of NVO are improved by F-doping. The enhanced electronic conductivity accelerates the electron transfer and the expanded interlayer spacing expedites the diffusion kinetics of zinc ions. As a result, the F-doped NVO (F-NVO) electrode shows a high discharge capacity (465 mAh g −1 at 0.1 A g −1 ), good rate capability (260 mAh g −1 at 5 A g −1 ), and long-term cycling stability (88% capacity retention over 2000 cycles at 4 A g −1 ). The reaction kinetics and energy storage mechanism of F-NVO are further validated by in situ and ex situ characterizations.

Ice accumulation is an important challenge for daily life and industrial production. The photothermal effect offers a promising approach for active de-icing to address this issue. While the photothermal effect of polyphenol-metal ion complex is extensively studied in photothermal cancer therapy, its application in de-icing remains relatively unexplored. Herein, a durable photothermal superhydrophobic coating was designed by combining F-SiO 2 @Tp/Fe (Tea polyphenol-Fe 3+ ) nanoparticles and silicone resin using a one-step spray method. Due to the unique micro-nano structure, the resulting coating exhibited excellent superhydrophobicity, characterized by water contact angle (CA) of up to 159° and sliding angle (SA) of less than 2.5°. Additionally, the coating demonstrated reliable mechanical durability and chemical stability, as evidenced by its good performance in sandpaper abrasion, tape peeling and electrochemical corrosion tests. Moreover, owing to the efficient photothermal conversion of F-SiO 2 @Tp/Fe nanoparticles , surface temperature of the coating can quickly reach 81 ℃ under 1 kW/m 2 simulated sunlight irradiation (1 Sun). The prepared coating exhibits over three times delayed icing time under 1 sun irradiation at − 25 °C in comparison to the absence of light. And the coating also exhibits stable de-icing and defrosting cycle performance. These findings demonstrate effective synergistic effect of anti-icing and de-icing in the F-SiO 2 @Tp/Fe photothermal superhydrophobic coating, showcasing its promising application potential in practical engineering.

Photocatalytic ozonation (PCO) was a novel water treatment method, but the low photo-generated electron ( e - ) utilization and ambiguous ROS formation mechanism restrained its performance. Herein, C vacancy and F co-decorated g-C 3 N 4 (FCN_Cv) was designed to accelerate the PCO performance with sodium p -perfluorinated nonoxybenzenesulfonate (OBS) acting as model pollutant. Comparative characterizations revealed that FCN_Cv remained the inherent structure of g-C 3 N 4 (BCN), and had an enhanced conduction band potential, narrower band gap and longer e - lifetime. FCN_Cv exhibited the greater activity over BCN, with 99.3 % OBS removal in 30 min but only 78.3 % for BCN during PCO process. •OH was the main ROS for degrading OBS. The greater •OH yield was obtained by FCN_Cv PCO process because of the increase of e - utilization. On one hand, the two electrons reduction of O 2 into H 2 O 2 on FCN_Cv was accelerated, which triggered the peroxone reaction between photogenerated-H 2 O 2 and O 3 . On the other hand, the direct one electron reduction of O 3 by e - also accounted for •OH generation. 17 kinds of intermediates were detected and the OBS degradation routes were inferred, which was involved with hydroxylation, C-O cleavage and aromatic ring opening reactions. Overall, this study demonstrated the feasibility of decorating F element and C vacancy on g-C 3 N 4 in enhancing e - utilization and •OH generation during PCO process as well as deepened the understanding of fate of OBS in PCO process.

Emulsifier-free polymerization was employed to prepare the submicron spherical PSA (the copolymer of styrene and acrylic acid), then SiO 2 was grown on the surface of the PSA by sol-gel method to form F–SiO 2 @PSA particles. It was found that when styrene: acrylic acid = 2.5:1 and tetraethyl orthosilicate : PSA was between 2.17:1 and 6.38:1, a perfect raspberry-like structure could be obtained. The coating based on F–SiO 2 @PSA particles exhibited contact angles of 167.3 ± 1.4°, 152.1 ± 1.5°,150.3 ± 1.6°, 150.9 ± 1.6°, 142.2 ± 1.7°, 143.7 ± 1.5° and 146.6 ± 1.9° to water, diiodomethane, soybean oil, rapeseed oil, hexadecane, kerosene, and waste engine oil , respectively. The F–SiO 2 @PSA coating could reduce the adsorption of protein by 90% compared with the control surface . It was observed that bacteria and platelets could hardly adhere to the coating surface after 24 h of E. coli culture and 3 h of platelet-rich plasma immersion. The anti-adhesion to proteins, platelets, and bacteria will give the coating a promising application in the medical field.
