Fluoride ion batteries (FIBs) have garnered significant attention due to their ultrahigh theoretical energy density, dendrite-free safety, and resource abundance. Although some anion acceptors have been proposed to address the insolubility of inorganic fluoride salts, the difficulty in dissociating fluoride ions from acceptors results in short lifespan and extremely low specific capacity of FIBs. Here, a fluoride ion battery is demonstrated with unprecedented long life and ultrahigh specific capacity through the design of an acceptor-multi-F state electrolyte. The high Lewis acidity of triphenylantimony chloride (TSbCl) as a novel anion acceptor in electrolyte facilitates the complete dissociation of CsF, and the resulting TSbCl-F complex can further interact with fluoride ions to form the acceptor-multi-F states. This strategy combines the high dissociation capability for fluoride salts with the minimal thermodynamic barriers for releasing fluoride ions at electrode-electrolyte interface. This electrolyte design endows FIBs with durable reversible fluorination/defluorination reaction (3700 cycles with high coulombic efficiency of 99.5% and small voltage polarization of 30 mV) and ultrahigh reversible capacity (580 mAh g −1 after 40 cycles at 100 mA g −1 ). The high-output voltage FIBs of CuF 2 //Li configuration (with discharge plateau of 2.9 V) and larger-sized pouch-type FIBs of CuF 2 //Sn+SnF 2 configuration (with reversible capacity of 530 mAh g −1 ) are demonstrated.

Microplastics (MPs) can adsorb and desorb organic pollutants, which may alter their biotoxicities. Although the toxicity of perfluorooctane sulfonate (PFOS) and its alternative 6:2 chlorinated polyfluorinated ether sulfonate (F-53B) to organisms has been reported, the comparative study of their combined toxic effects with MPs on aquatic organisms is limited. In this study, adult female zebrafish were exposed to 10 μg/L PFOS/F-53B and 50 μg/L MPs alone or in combination for 14 days to investigate their single and combined toxicities. The results showed that the presence of MPs reduced the concentration of freely dissolved PFOS and F-53B in the exposure solution but did not affect their bioaccumulation in the zebrafish liver and gut. The combined exposure to PFOS and MPs had the greatest impact on liver oxidative stress, immunoinflammatory, and energy metabolism disorders. 16S rRNA gene sequencing analysis revealed that the combined exposure to F-53B and MPs had the greatest impact on gut microbiota. Functional enrichment analysis predicted that the alternations in the gut microbiome could interfere with signaling pathways related to immune and energy metabolic processes. Moreover, significant correlations were observed between changes in gut microbiota and immune and energy metabolism indicators, highlighting the role of gut microbiota in host health. Together, our findings demonstrate that combined exposure to PFOS/F-53B and MPs exacerbates liver immunotoxicity and disturbances in energy metabolism in adult zebrafish compared to single exposure, potentially through dysregulation of gut microbiota.

MO-ZrO 2 -Ta 2 O 5 (M = Zn, Co) ceramics were prepared by solid-phase reaction method. Thermo-gravimetric-differential thermal behavior, crystal structure, and microwave dielectric properties of ZnO-ZrO 2 -Ta 2 O 5 and CoO-ZrO 2 -Ta 2 O 5 ceramics were compared in this paper. Both of them exhibited monoclinic wolframite structure. Densest microstructures with uniform grains were obtained at 1400°C and 1425°C in the cases of M = Zn and Co, respectively. ZnO-ZrO 2 -Ta 2 O 5 and CoO-ZrO 2 -Ta 2 O 5 exhibited comparable ε r ~ 20.26 and 24.30, while the former had Q × f ~ 60, 983 GHz and the latter had Q × f ~ 95,300 GHz. The grain growth exponent and activation energy obtained from the phenomenological kinetic equation indicated the growth process of ceramics. The grain growth of Zn-based ceramic was dominated by interfacial reactions and lattice diffusion. For the other one, the grain growth mechanisms were grain boundary diffusion and lattice diffusion at high temperatures. The grain growth progress of them both affected by lattice diffusion. The growth process of ZnO-ZrO 2 -Ta 2 O 5 ceramics was faster than that of CoO-ZrO 2 -Ta 2 O 5 ceramic. However, the grains were overgrown and grew slowly at 1425°C and 1450°C, which was caused by the excessive high temperature.

The widespread application of bisphenols (BPs) in the industry has made them ubiquitous in the environment, causing potential environmental risks. Its unknown impacts on human being have received more and more attention. In this study, we have assessed the metabolic effects of perinatal exposure to bisphenol A (BPA) and its substitutes (bisphenol S (BPS), bisphenol F (BPF), and bisphenol AF (BPAF)) in female mice adolescent offspring and female mice adulthood offspring. 1 H NMR-based serum metabolomics showed that metabolic profiles were disturbed with BPA and its three substitutes exposure in female mice adolescent offspring and female mice adulthood offspring. In addition, age-related metabolic effects were found based on changes in serum endogenous metabolites and metabolic pathways. Specifically, metabolic pathway analysis showed that major disturbed metabolic pathways in female mice adulthood offspring compare with female mice adolescent offspring also changed significantly. With the increase of age of the female mice offspring, changes in the metabolic pathways became more obvious in the BPA treatment group. Conversely, partially disturbed metabolic pathways were restored in the BPS, BPF, and BPAF treatment groups. In conclusion, perinatal exposure to BPA and its three substitutes significantly interferes with metabolic profiles and metabolic pathways, and this metabolic effects were age-related. These results offer more detailed information about the age-related metabolic effects of perinatal exposure to BPA, BPS, BPF, and BPAF in female mice offspring and provide data for systematic evaluation of the health risk assessment of BPA and its substitutes.

This research aimed to analyze the biocompatibility and growth behavior of human immunodeficiency virus (HIV)-associated colorectal cancer (CRC) cells on a polylactic acid/polyglycolic acid (PLA-PCL) composite nanofiber scaffold (CNS) using proteomic analysis. The PLA-PCL CNS was prepared
using a gel extraction phase separation (GEPS) method in a dioxane/ethanol solvent system, and the effects of gel temperature, PLA-PCL mass ratio (MR), solvent-to-polymer MR on the structure and properties of the PLA-PCL CNS were analyzed. Subsequently, Lappaol F (LAF) was incorporated into
the PLA-PCL CNS using electrospinning (ES) technology, and tissue specimens were obtained from HIV-associated CRC patients to investigate the impacts of LAF-PLA-PCL CNS on the growth behavior of HIV-associated CRC cells through mass spectrometry and bioinformatics analysis. Field emission
scanning electron microscopy (FE-SEM) revealed that the CNS could be obtained at gel temperatures between −20 °C and −10 °C, PLA-to-PCL MRs of 1:1, 3:2, 7:3, and ethanol content of 5%–15%. X-ray diffraction (XRD) and differential scanning calorimetry (DSC) showed
that the PLA-to-PCL MR of 70:30 exhibited compatibility and crystallinity of the PLA-PCL CNS, while the porosity increased with an increase in PCL content. Fourier-transform infrared spectroscopy (FTIR) analysis indicated a good biological activity of the PLA-PCL CNS. The relative cell proliferation
(RCP) and cytotoxicity grades exhibited no marked differences (P >0.05) between the cancer cells cultured with DMEM and those with PLA-PCL scaffold extract over time. Proteomic analysis identified 127 differentially expressed proteins (DEPs) in HIV-associated CRC cells co-cultured
with LAF-PLA-PCL CNS, and Gene Ontology (GO) protein and KEGG pathway enrichment analysis (KEGG analysis) revealed that the LAF-PLA-PCL NCS could affect the cell cycle (CC) of HIV-associated CRC cells. In conclusion, the PLA-PCL NCS exhibited good compatibility, crystallinity, and biological
activity, while the LAF-PLA-PCL NCS showed the potential to inhibit cell proliferation by affecting the CC.

Sea cucumber peptides have been shown to possess a number of functions, including antioxidant, anti-inflammatory, anti-tumor, and anti-fatigue effects, as well as immune regulation and promotion of collagen synthesis. Among these, high F-value oligopeptides are a promising natural active ingredient demonstrating excellent anti-fatigue effects. This study utilized fresh sea cucumbers as the primary raw material, employing membrane separation technology to investigate the simultaneous separation of sea cucumber polysaccharides and peptides. The process for removing aromatic amino acids during the preparation of high F-value oligopeptides from sea cucumbers was optimized, and the mechanism underlying their anti-fatigue effects was explored. A two-step enzymatic hydrolysis method using neutral protease and composite flavor protease was employed, followed by membrane separation using a 10,000 Da molecular weight ultrafiltration membrane, yielding a sea cucumber peptide yield of 45.00 ± 0.12% and a sea cucumber polysaccharide yield of 51.28 ± 0.63%. Following the removal of aromatic amino acids by means of activated carbon adsorption, the F-value of the high-F-value oligopeptides attained 23.82, with a yield of 24.56%. The experimental findings demonstrated that high-F-value oligopeptides exhibited a substantial increase in the swimming duration of mice and a notable enhancement in their grip strength. These observations signified their substantial anti-fatigue potential. Furthermore, studies have indicated that sea cucumber high-F-value oligopeptides reduce metabolites produced by exercise, enhance muscle protection, increase the activity of antioxidant enzymes in the body, and alleviate fatigue, thereby achieving an anti-fatigue effect.

This work developed a fluorescence polarization (FP) assay for simultaneous monitoring BPA, BPF, BADGE, and BFDGE in canned tuna. The assay was based on the competitive binding between bisphenol analogues (BPs) and dexamethasone fluorescein (Dex-fl) for mouse peroxisome proliferator-activated receptor α ligand binding domain (mPPARα-LBD*). The soluble form of mPPARα-LBD* was expressed in Escherichia coli strain Rosetta (DE3), as a recognition element on detection of BPs. Under optimized conditions, four bisphenol analytes were detected at concentrations corresponding to the specific migration limits (SMLs) as required by the European Union. The FP assay showed IC50 values of 2.80, 6.51, 1.72, and 4.28 mg L−1 with a limit of detection of 0.35, 0.08, 0.10, and 0.49 mg L−1 for BPA, BPF, BADGE, and BFDGE, respectively. The analysis of spiked canned tuna samples showed the acceptable recoveries ranged from 87.9% to 77.3%, with variation coefficients ranging from 9.0% to 15.8%. With the high sensitivity and wide-range affinities to BPs, the developed assay based on mPPARα-LBD* exhibited the potential to be a screening assay for fast detection of BPs in canned tuna.

Core-shell F-doped carbon coated SiO composites with interspaces and some small voids (SiO@F-doped C) are successfully fabricated using bulk SiO as starting material. With the assistance of polytetrafluoroethylene (PTFE), both etching and carbon coating of SiO are firstly performed in a single step, which largely lowers the production cost of materials. The SiO@F-doped C composite obtained by annealing the mixture of SiO and PTFE with a mass ratio of 5:3 at 650 °C shows the highest stable discharge capacity with excellent cycling stability. It delivers a stable discharge capacity of about 975 mAh g −1 at a current density of 100 mA g −1 . Even after the current density increases to 1600 mA g −1 , a stable discharge capacity of about 553 mAh g −1 can be achieved. At a current density of 400 mA g −1 , the composite maintains a discharge capacity of 752 mAh g −1 after 350 cycles, the retention of which is 99.2% versus that in the second cycle. Compared with the annealed SiO, in addition to higher conductivity, the ions diffusion rate of the SiO@F-doped C composite increases 2.94 times while the volume expansion falls by more than half, which should be responsible for its significantly enhanced electrochemical performance.

Next-generation wide color gamut displays require the development of efficient and toxic-free light-emitting materials meeting the crucial Rec. 2020 standard. With the rapid progress of green and red perovskite light-emitting diodes (PeLEDs), blue PeLEDs remain a central challenge because of the undesirable color coordinates and poor spectra stability. Here, we report Cs 3 CeBr x I 6− x ( x = 0 to 6) with the cryolite-like structure and stable and tunable color coordinates from (0.17, 0.02) to (0.15, 0.04). Further encouraged by the short exciton lifetime (26.1 ns) and high photoluminescence quantum yield (~76%), we construct Cs 3 CeBr x I 6− x -based rare-earth LEDs via thermal evaporation. A seed layer strategy is conducted to improve the device’s performance. The optimal Cs 3 CeI 6 device achieves a maximum external quantum efficiency of 3.5% and a luminance of 470 cd m −2 with stable deep-blue color coordinates of (0.15, 0.04). Our work opens another avenue to achieving efficient and spectrally stable deep-blue LEDs.

Exorbitant cost and limited availability of platinum-based electrocatalysts for the oxygen reduction reaction (ORR) in metal–air batteries and alkaline fuel cells pose significant obstacles to the large-scale commercialization of these clean-energy technologies. Herein, we employed a cost-effective and sustainable bacterial cellulose biomass as the precursor to prepare a nitrogen and fluorine codoped metal-free ORR electrocatalyst (BCC-NF-900) by direct pyrolysis regulation. The BCC-NF-900 inherited the three-dimensional framework of bacterial cellulose, exhibiting a robust porous structure with a Brunauer–Emmett–Teller surface area of 196.9 m 2 ·g −1 . The pyridinic N (0.6 at%) and semi-ionic F (0.34 at%) species formed in the inert sp2 carbon skeletons synergistically regulated the electron spin and charge density of the adjacent C atoms. Such rational combination of a rapid transport pathway and effective active site led to high ORR activity (onset potential 0.89 V vs. RHE), methanol resistance, and electrochemical stability (merely 6.9% current loss) in alkaline electrolyte. Importantly, compared to the mere F-doped BCC-F-900 (onset potential 0.82 V vs. RHE) and N-doped BCC-N-900 (onset potential 0.77 V vs. RHE) catalysts, the BCC-NF-900 catalyst exhibited a markedly enhanced ORR performance, as evidenced by the measured onset potential. This study provides an available reference for the design of efficient metal-free catalysts for ORR, presenting a promising alternative to Pt/C catalysts in metal–air batteries and alkaline fuel cells.

Aiming for promoting the capacity and cycling stability of O3-type NaNi 1/3 Fe 1/3 Mn 1/3 O 2 (NFM), the cathode material of sodium ion batteries (SIBs) with the most potential for industrialization, Na(Ni 1/3 Fe 1/3 Mn 1/3 ) 0.99 Mo 0.01 O 1.99 F 0.01 (NFM-MoF), Na(Ni 1/3 Fe 1/3 Mn 1/3 ) 0.99 Mo 0.01 O 2 (NFM-Mo) and NaNi 1/3 Fe 1/3 Mn 1/3 O 1.99 F 0.01 (NFM-F) were successfully synthesized by solid phase method. The electrochemical performance of the doped samples was compared with that of the pristine NFM. The mechanism of the single- or dual-doping was explored by XRD Rietveld refinement and XPS. The NFM-MoF exhibits the highest initial specific discharge capacity of 137mAhg −1 at 1 C with a retention of 91.97% after 100 cycles and the smallest polarization (0.32 V), which could be contributed to the highest Ni 2+ content and highest D Na + (7.335 ×10 −13 cm 2 ·s −1 ) caused by the synergistic effect of Mo and F dual-doping. The highest Fe 3+ content in the NFM-Mo leads to the higher initial discharge capacity of 1 36 mAhg −1 at 1 C with a relative lower retention of 83.38%, which is due to the structure instability resulting from Fe migration and the lowest Mn content, than that of the NFM-F (85.31%). It illustrates that the Mn 4+ plays a crucial role in stabilizing the structure during Na + migrating. The superiority of the discharge capacity of the NFM-Mo become narrow with rates rise, due to its lower D Na + (4.229 ×10 −13 cm 2 ·s −1 ) than that of the NFM-F D Na + (5.681 ×10 −13 cm 2 ·s −1 ). It verifies that it is a diffusion control process at high rates. Mo and F dual-doping in NFM was proved to amplify the benefit of Ni 2+ increasing, meanwhile restrain undesirable Fe increasing due to the synergistic effect.

The organic pollutants discharged from industrial wastewater have caused serious harm to human health. The efficient photocatalytic degradation of organic pollutants under sunlight shows promise for industrial applications and energy utilization. In this study, a modified TiO2photocatalyst doped with bismuth (Bi) and fluorine (F) and composited with SnO2and SiO2was prepared, and its performance for the degradation of Rhodamine B (RhB) under simulated sunlight was evaluated. Through the optimization of the doping levels of Bi and F, as well as the ratio of SnO2and SiO2to TiO2, the optimal catalyst reached degradation efficiency of 100% for RhB within 20 min under simulated sunlight, with a first-order reaction rate constant of 0.291 min−1. This value was 15, 41, 6.5, and 3.3 times higher than those of TiO2/SnO2, Bi/TiO2, Bi-TiO2/SnO2, and F/Bi-TiO2/SnO2, respectively. The active species detection showed that h+was the most crucial active species in the process. The role of Bi and F addition and SnO2-SiO2compositing was investigated by characterization. Bi formed a chemical bonding with TiO2by doping into TiO2. The absorbance intensity in the UV and visible light regions was improved by SnO2and F modification. Composite with SiO2led to a larger surface area that allowed for more RhB adsorption sites. These beneficial modifications greatly enhanced the photocatalytic activity of the catalyst.
