A facile and green method was developed for the simultaneous doping of nitrogen, boron, and fluorine in TiO 2 by H 2 TiO 3 via a microwave-assisted route. The ionic liquid (IL) [BMIm]BF 4 serves not only as microwave absorbent but also as a dopant. The IL also shows the ability to self-assemble under microwave irradiation, which causes it to act as an inhibitor for the growth of the TiO 2 particles. The N–B–F-tri-doped TiO 2 obtained exhibits large specific surface area, small crystal size, and a mesoporous structure, and the mechanism for the formation of the N–B–F-tri-doped TiO 2 was proposed. The prepared materials exhibit excellent visible light photocatalytic activity in the degradation of organic pollutants, including methyl orange, rhodamine B, Orange G, and reactive red X, which is attributed to the presence of a Ti–B–N structure on the TiO 2 surface, inducing a narrow band gap of 2.78 eV, and the synergistic effects of N, B, and F, which improve the separation efficiency of the photo-generated electron/hole pairs. The results obtained may provide a new sight for the application of ILs in the microwave-assisted preparation of nanomaterials.

In this study, the F-doped poly-m-phenyleneisophthalamide (PMIA) solution was synthesized by low temperature polymerization method and spun to be three-dimensional nanofibrous membranes by electrospinning. The Energy Dispersive X-Ray Spectroscopy and Fourier Transform Infrared Spectroscopy investigations verified that F was successfully doped in PMIA membrane. The X-ray diffraction patterns showed the crystallinity degree of PMIA membrane decreased with the addition of F. The morphology, pore size and aperture distribution tests manifested that the average diameter of F-PMIA fibers became finer and their distribution was more uniform than these of PMIA fibers. The electrolyte uptake, preserving liquid electrolyte, thermal stability and shrinkage resistance of the F-dopoed membrane were also significantly enhanced than that of pure PMIA membrane. The F-PMIA membrane could be acted as matrix to prepare gel polymer electrolyte. Finally, the F-doped PMIA membrane was used in the assembled coin cells to test the properties including the electronic conductivity , battery interfacial characteristics, electrochemical stability windows and cycle performances of battery. The lower electronic conductivity and interfacial resistance , higher electrochemical stability window (5.7 V) of F-doped PMIA membranes were obtained when comparing to the pure PMIA and commercial polyethylene membrane. The cell exhibited high first-cycle discharge capacity with 145 mAh g −1 and excellent cycling stability with good capacity retention of 93.1% and coulombic efficiency of 99.3% after 100 cycles.

White light with excellent color rendering property has been highly required for comfortable and healthy illumination. A facile strategy to achieve high color rendering index (Ra >90) in practical applications is using near ultraviolet chips as excitation sources combined with RGB phosphors. However, achieving high color rendering with both blue chips and near-ultraviolet (NUV) chips for commercial phosphors dispersed in phosphor-in-glass (PiGs) materials is still a big challenge. In this work, the PiG based on the ultra-low melting point Sn–F–P–O glass with commercial green (Lu 3 Al 5 O 12 :Ce 3+ ) and red (Sr x Ca 1-x AlSiN 3 :Eu 2+ ) phosphors has been successfully fabricated by one-step sintering method. The phase identification and distribution of monochromatic red phosphor in glass (R-PiG) and green phosphor in glass (G-PiG) were investigated in detail. The Sn 2+ ions in Sn–F–P–O matrix show the intense blue emission bands centered at 420 nm under the excitation of NUV chips (365 nm). Notably, the polychromatic red/green phosphor in glasses (R/G-PiGs) are versatile and exhibited excellent color rendering (Ra = 93, Ra = 95, Ra = 92, respectively) properties excited by both blue chips, NUV chips and laser diodes (WLD). The working temperature of R/G-PiGs is stable at ∼33 °C and ∼55 °C when employed in WLEDs/WLDs (1 W), which greatly prevented the phenomenon of “thermal quenching” for the phosphors caused by high temperature. Thus, the versatile R/G-PiG with ultra-high color rendering and excellent thermal properties indicates its promising application in high-power white LEDs/LDs.

High-performance earth-abundant electrocatalysts for oxygen evolution reaction (OER) are highly desirable. In this report, we successfully synthesized amorphous Fe−P shell electrodeposited on Co(OH)F nanowire arrays supported on titanium mesh (Fe−P@Co(OH)F/TM) as an efficient catalyst for OER. Such catalyst exhibits excellent OER activity with a low overpotential of 267 mV to reach the geometrical current density of 10 mA cm −2 in 1.0 M KOH. In addition, it has good electrochemical durability to maintain its activity for at least 20 h.

The wide occurrence of metronidazole (MNZ) in aquatic environment has aroused increasing concern to the potential adverse effects on human health. Combining different motifs into a photolytic material to achieve high photocatalytic efficiency is regarded as one of the main strategies during photocatalytic process. Herein, a triple anions contained photocatalyst , Ba 3 (BO 3 )(CO 3 )F (BBCF), exhibited excellent removal efficiency of MNZ (92.6%) in 15 min, which was 5.87 times higher than that of commercial P25. The excellent removal efficiency could be attributed to the strong electronegativity of the F − , and the π-conjugated triangles structure of (BO 3 ) 3− and (CO 3 ) 2− , which made BBCF facilitate the transport of photogenerated electrons, thus accelerating the accumulation of active h + . Meanwhile, the appropriate reduction potential of BBCF accounted for the outstanding productivity of O 2 – . h + and O 2 – were proved as the dominant reactive species for MNZ degradation. The degradation products were analyzed by LC-TOF-MS, and the toxicity of the intermediate was evaluated to be lower than that of parent MNZ molecule. Moreover, BBCF showed the universal application of degrading oxytetracycline (OTC), methylene blue (MB). Therefore, anion-rich BBCF catalyst with high catalytic activity has a potential application prospect for degrading harmful pollutants in practical water environment.

Fluoride-containing wastewater pollution poses a serious threat to the global environment. Adsorption represents the most widely employed defluoridation process. Among various adsorbents, metal-organic frameworks (MOFs) demonstrate considerable potential. However, current zirconium-based MOFs for fluoride removal face challenges such as high cost, low adsorption capacity, insufficient mechanistic understanding, and difficulties in reuse due to the lack of stable immobilization methods. Herein, a zirconium‑cerium MOF (denoted as Zr/Ce-M) was prepared by doping MOF-801 with the low-cost metal cerium. At an initial F − concentration of 26 mg/L, its actual adsorption capacity reached 213 mg/g. This represents a 326% improvement compared to conventional MOF-801 and is 66% higher than the adsorbent with the highest known adsorption capacity.Further, zirconium/cerium MOF-based sponge (Zr/Ce-MS) was prepared via a simple method. Zr/Ce-MS exhibited exceptional loading stability under mechanical stress and solvent corrosion. Regeneration tests confirmed effective fluoride removal after eight cycles. Computational results revealed an upward shift in the d-band center of metals and enhanced electron-donating capability after Ce doping. Monodentate coordination (Zr F and Ce F) proved more stable than μ₂- or μ₃-bridging configurations. Strong hybridization occurred between Zr d/Ce d and F p orbitals, with Ce doping strengthening electron transfer from Zr to F − . The defluoridation mechanism of Zr/Ce-MS involves ion exchange, electrostatic interactions, hydrogen bonding, and Lewis acid–base complexation.This work provides new insights for developing fluoride adsorbents and mechanistic analysis.

Fusarium wilt, caused by the soil-borne fungusFusarium oxysporumf. sp.lycopersici(Fol), is a devastating disease that severely constrains tomato production worldwide. In this study, an endophytic bacterium, designated ZN-S18, was isolated from healthy tomato stems and identified asBacillus amyloliquefaciensbased on phylogenetic analyses of the 16S rRNA andrpoBgenes. Dual culture assays demonstrated that ZN-S18 exhibited strong antagonistic activity against Fol and significantly inhibited fungal mycelial growth. The cell-free culture filtrate of ZN-S18 markedly suppressed Fol spore germination and mycelial growth, and the inhibitory effect on spore germination was irreversible. LC-MS analyses confirmed that ZN-S18 produces the cyclic lipopeptides surfactin and iturin A. In planta assays further demonstrated that pretreatment with ZN-S18, its culture filtrate, or the combination of surfactin and iturin A significantly reduced Fusarium wilt in tomato seedlings. Moreover, the culture filtrate disrupted fungal cell wall integrity, as indicated by the increased sensitivity of Fol to Congo red stress. Notably, the combined application of surfactin and iturin A exhibited significantly stronger antifungal activity than either compound alone under Congo red-containing conditions, suggesting a synergistic effect on fungal cell wall integrity. Collectively, these findings indicate that the endophytic strainB. amyloliquefaciensZN-S18 is a promising biocontrol agent against tomato Fusarium wilt, primarily through the synergistic action of surfactin and iturin A. This study provides an environmentally friendly alternative to chemical fungicides and establishes a foundation for future investigations into the molecular mechanisms underlying lipopeptide-mediated antagonism.

Precise control of the photogenerated charge dynamics and the electronic configuration of active sites is key to enhancing the performance of photocatalytic hydrogen-producing materials. Here, we report an efficient one-pot strategy to prepare sulfur-doped g-C 3 N 4 (SCN). Furthermore, a PtNd/SCN composite photocatalyst was successfully fabricated by loading a platinum (Pt)‑neodymium (Nd) alloy onto the SCN surface via an H 2 reduction method. Using trithiocyanuric acid as a single precursor to supply C, N, and S enables uniform S doping within the g-C 3 N 4 framework, broadening the light absorption range and optimizing the band structure. Pt serves as the primary hydrogen-evolving active site, while Nd acts as an “electronic co-catalyst” for Pt, forming strong electronic interactions through its unique 4f orbital structure. HRTEM and XPS analyses confirm the formation of a Pt Nd alloy interface and directional electron transfer from Nd to Pt, effectively modulating the Pt d-band center and optimizing the adsorption free energy of hydrogen intermediates, thereby significantly enhancing hydrogen evolution reaction (HER) kinetics. The experimental results show that the optimized PtNd/SCN composite photocatalyst exhibits a markedly enhanced photocatalytic hydrogen production rate under simulated sunlight, reaching 5468 μmol·g −1 ·h −1 —5 times higher than Pt/CN (1074 μmol·g −1 ·h −1 ) and 1.3 times that of Pt/SCN (4076 μmol·g −1 ·h −1 ). PL, TRPL, and photoelectrochemical measurements confirm that the introduction of Nd promotes the migration of photo-generated electrons from SCN to Pt, thereby significantly suppressing carrier recombination. This study reveals the unique mechanism by which the rare earth element Nd acts as an electronic regulator for the d-band center of Pt, providing new insights into the design of photocatalytic systems with low Pt loading.

Antibody-targeted radioimmunotherapy holds significant potential for solid tumor treatment. However, intact antibodies (IgG) and fragments (F(ab’) 2 ) may exhibit distinct pharmacokinetic and radiation delivery properties due to differences in molecular size and Fc functionality. TROP2 is highly overexpressed in most malignant tumors but minimally expressed in normal tissues. Therefore, the anti-TROP2 antibody was selected as the targeting agent in this study. We prepared the F(ab’) 2 antibody fragments of anti-TROP2 antibody and systematically compared the in vitro and in vivo behaviors of [ 177 Lu]Lu-DOTA-anti-TROP2 antibody and [ 177 Lu]Lu-DOTA-anti-TROP2-F(ab’) 2 antibody fragments to optimize radioligand therapy strategies. Cell binding assays were conducted to evaluate their TROP2 antigen binding affinity. In vivo distributions in tumors and normal organs were investigated through Micro-SPECT/CT imaging and biodistribution studies using tumor-bearing mice. The results demonstrated that, compared to the anti-TROP2 antibody, the anti-TROP2-F(ab’) 2 antibody fragments exhibited superior blood clearance kinetics as well as lower accumulation in liver and spleen. This could reduce the radiation side effects of [ 177 Lu]Lu-DOTA-anti-TROP2-F(ab’) 2 antibody fragments on bone marrow or other full-antibody target normal organs. However, cutting Fc from the full anti-TROP2 antibody increased renal accumulation and exhibited shedding phenomena following tumor targeting.

Cr/F co-doped LiMn 2 O 4 was compared with undoped, Cr-only and F-only spinel controls. • Co-doping raised 1C capacity to 124.6 mAh g −1 and HCDI Li + uptake to 35.07 mg g −1 . • The co-doped electrode kept 83% of its Li + uptake over 100 cycles with 1.4% Mn loss. • A reference-cell test traced most capacity fade to the carbon counter electrode. • Li + /Mg 2+ separation factor of 24.0 in untreated old brine with acid-free desorption. Spinel LiMn 2 O 4 (LMO) is a Li + -selective intercalation host for hybrid capacitive deionization (HCDI), but Jahn–Teller distortion and Mn dissolution limit its durability in Mg-rich brines. Here, Cr 3+ and F − were introduced at the nominal cationic and anionic sites of LMO to obtain LiCr 0.05 Mn 1.95 O 3.95 F 0.05 (CFLMO), and undoped, Cr-only (CrLMO) and F-only (FLMO) controls were prepared by the same route. XRD and FTIR showed that the average spinel framework was retained, and Cr 2p and F 1s XPS detected both added elements near the CFLMO surface. At 1C, CFLMO delivered a discharge capacity of 124.6 mAh g −1 (84% of the theoretical value), compared with 92.1 mAh g −1 for LMO. In HCDI tests with 32.74 mg L −1 Li + , CFLMO reached a salt adsorption capacity (SAC) of 35.07 mg g −1 at a charge efficiency of 0.89. After 100 adsorption–desorption cycles against an activated‑carbon (AC) counter electrode, CFLMO retained 83% of its initial SAC with a Mn dissolution ratio of 1.4%; replacing the AC electrode in an LMO||AC reference cell restored part of the lost adsorption response, identifying a counter-electrode contribution to cell-level capacity loss. In untreated Yiliping salt-lake old brine (Mg 2+ /Li + mass ratio 36.1), three CFLMO electrodes recovered 37.5 ± 1.5 mg g −1 Li + with a Li + /Mg 2+ separation factor of 24.0 ± 2.7, and desorption into pure water lowered the Mg 2+ /Li + mass ratio to 1.52 ± 0.18. The matched-control and real-brine results support Cr/F-modified LMO as a candidate for selective lithium recovery from Mg-rich salt-lake brines.

Hepatocellular carcinoma (HCC) remains a highly malignant cancer with limited treatment options. HCC cells (HCCs) activate hepatic stellate cells (HSCs) and transform them into cancer-associated fibroblasts (CAFs), forming a vicious cycle for hepatocarcinogenesis. Therefore, inhibition of the communication between HCCs and HSCs is expected to emerge as a novel strategy for HCC treatment. Artematrolide F (AF), a sesquiterpenoid dimers (SDs) isolated from Artemisia atrovirens , exhibited significantly inhibitory activity on tumor cells in our previous report, but its mechanism remains unknown. This further study demonstrated that AF significantly inhibited the proliferation, colony formation and metastasis of HCCs. Notably, the inhibitory effect was enhanced when HCCs were cocultured with HSCs, suggesting that AF may suppress tumor progression through regulating the crosstalk of HCCs and HSCs. The vesicular transport protein YKT6 was identified as a target of AF through integrating bioinformatics analysis and machine learning model, which were verified by DARTS, CETSA, molecular docking, molecular dynamics simulation, and knockdown experiments. Further mechanistic research revealed that AF targeting YKT6 disrupted the crosstalk between HSCs and HCCs, suppressed HSC-driven tumor proliferation by inhibiting extracellular vesicles (EVs) secretion from HCCs, and blocked tumor autophagy by disrupting vesicular transport. These findings demonstrate that AF could serve as a novel therapeutic candidate for HCC treatment through regulating YKT6 to suppress HCCs–HSCs communication, block EV-dependent tumor progression, and inhibit tumor autophagy.

High-quality SnO 2 :F films with an area of 15×15 cm 2 were prepared from stannic chloride (SnCl 4 ) solution via a house-made ultrasonic spray pyrolysis instrument. The focus of this investigation was on the volatilization of solution and doping process of fluorine, the main influencing factors on F doping content, and the effects of F doping content on the crystal structure, surface morphology, electrical, and optical properties. The results indicated that the crystallinity was enhanced with increasing doping concentration; the films exhibited (101) oriented growth and the resistivity decreased at first and then increased. During the preparation route, the droplet momentum and the temperature field above the hot plate demonstrate the most dominate influence on the film’s properties. The spray droplet gradually hydrolyzed during the moving process from sprinkler to substrate while the F doping content decreased with the increasing distance between the sprinkler and the substrate. By controlling the doping of F, high-quality and large area SnO 2 :F films with a resistivity of 1.2×10 -3 Ω⋅cm and a visible light transmittance of 82% were prepared, demonstrating a promising application for organic solar cells and low emissivity glass.
