Cation regulation is a compelling strategy for developing new compounds with optimized crystal structure by atomic-scale manipulation. Herein, we report two new SBBO-like fluoroberyllium borates, SrMgBe₂(BO₃)₂F₂ (SMBBF) and SrZnBe₂(BO₃)₂F₂ (SZBBF). They crystallize in a trigonal system and feature a [Be₃B₃O₆F₃]∞ single layer stabilized by the incorporation of Mg²⁺/Zn²⁺ cations and F⁻ cations. Both compounds exhibit deep-UV absorption edges below 200 nm. Theoretical calculations confirm their potential as deep-UV birefringent materials, with correspinding birefringence values of 0.064 (SMBBF) and 0.063 (SZBBF) at 589 nm, respectively. This work demonstrates the effectiveness of cation regulation in designing novel borate-based optical materials.

Benzene, toluene, and xylene (BTX) gases pose severe threats to public health on account of their toxic, carcinogenic properties and environmental recalcitrance. In addition, their similar molecular structures and chemical inertness complicate the practical quantification of BTX, severely hindering their high-selectivity detection. In this work, a chemiresistive sensor based on F-doped In2O3nanofibers was constructed. This strategy successfully enhanced the sensor response values toward benzene, toluene, and xylene by approximately 4.3, 4.5, and 4.2 times, respectively. Meanwhile, the limits of detection were reduced from 1, 0.5, and 0.25 ppm to 0.5, 0.25 and 0.05 ppm, respectively. The theoretical lower detection limits for benzene, toluene, and xylene are as low as 9.9 ppb, 5.7 ppb, and 2.5 ppb, respectively. Machine learning methods were further employed for the identification of BTX gases and their binary mixtures. By capturing the distinctive and reproducible patterns of feature vectors from various analytes, the optimal algorithm established decision boundaries and achieved a classification accuracy of 92.1%. Meanwhile, the reasons for the improved gas sensing performance are discussed. Furthermore, a portable wireless gas sensing module based on F-doped In2O3nanofibers was developed, which can be applied for detecting BTX.

Li 3 VO 4 is one of the most promising candidates for high performance lithium-ion batteries due to its high specific capacity and excellent ionic conductivity , while its practical applications are hindered, because of its inferior rate capability. Herein, we adopted an anionic doping strategy to improve electronic conductivity, cycling stability and accelerate electrochemical kinetics. A series of F − doped Li 3 VO 4 samples were synthesized by a modified sol-gel method for the first time. F − doping led to the appearance of oxygen vacancies and reduced band gap, which effectively improve electronic conductivity. Complete structural rearrangement and optimized SEI layers also occurred during cycling, beneficial for stable lifetime. As a consequence, long cycle life (cycling 1100 loops at 500 mA g −1 except for the first 5 loops at 100 mA g −1 ) and optimized rate capability (255 mA h g −1 at 1000 mA g −1 ) were achieved for 5 at% F doping, which are superior to those for undoped samples. This work demonstrates that anion doping is a feasible strategy to accelerate electrons/ions transfer and improve cycling stability of Li 3 VO 4 .

Peroxymonosulfate (PMS)-based advanced oxidation processes have shown potential for the removal of organic contaminants; however, the preparation of catalysts with high degradation efficiencies and rapid reaction rates remains a challenge. In this study, we have successfully synthesized CoFe bimetallic modified corn cob-derived biochar (CoFe/BC) for the activation of PMS, achieving the rapid and efficient degradation of bisphenol F (BPF). The synthesized CoFe/BC catalyst demonstrated excellent catalytic performance, achieving over 99% removal within 3 min and exhibiting a removal rate of 90.0% after five cycles. This could be attributed to the cyclic transformation of Co and Fe, which sustained rapid PMS activation for BPF degradation, and Co0/Fe0played a significant role in the cyclic transformation. Furthermore, the electron paramagnetic resonance tests confirmed that •SO4−and •OH were the primary reactive oxygen species, while •O2−played a minor role in BPF degradation. This study highlights the high degradation efficiency, rapid reaction rate, excellent magnetic separation properties, and exceptional reusability of CoFe/BC catalysts for BPF removal, providing valuable insights for practical wastewater treatment.

With the increasing occurrences of industrial oily wastewater emissions and crude oil spills, the deteriorated global environment and ecosystems have attracted a great deal of attention worldwide. Herein we report a highly hydrophobic balsa wood sponge wrapped with fluoroalkyl silane modified reduced graphene oxide (F-rGO@WS) for efficient clean-up of all kinds of oils including viscous crude oil from water. The F-rGO@WS possessed excellent water repellency with a water contact angle of 145°. Owing to high hydrophobicity and longitudinal channels, the F-rGO@WS was successfully applied for separating oil-water mixtures, and the separation efficiency reached 99.0%. Furthermore, the F-rGO@WS also possessed quick electrothermal capability and could be utilized as a filter to efficiently separate viscous crude oil from water by means of the generated Joule heat under a low voltage, and the separation rate was about 10 times higher than that without voltage. Our findings stand out a new tool to fabricate functional natural materials and exhibit great potential in practical applications such as water pollution control and clean-up of viscous crude oil.

Fluoride ions (F − ) and per- and polyfluoroalkyl substances (PFAS) in industrial wastewater pose a serious threat to the global environment. Adsorption is the most widely used treatment technology for F − and PFAS in the field of water pollution control. However, existing zirconium-based MOFs face challenges such as the inability to synergistically and efficiently adsorb PFAS, high preparation costs, limited adsorption capacity, and an insufficiently understood adsorption mechanism in multi-component pollution systems. Here, we prepared a novel cerium/zirconium/lanthanum tri-metallic MOF (denoted as Ce/Zr/La-M) by doping low-cost metals and loaded it onto a sponge modified with dimethyloctadecyl[3-(trimethoxysilyl)propyl]ammonium chloride (DTSACL), ultimately obtaining Ce/Zr/La-MSD. The practical adsorption capacity of Ce/Zr/La-MSD for F − is 255 mg/g, which is the highest reported value at similar initial concentrations, while the removal rates for PFAS (C 6 -C 8 ) and PFAS (C 4 ) exceed 96% and 84%, respectively.DFT calculations revealed that doping with La shifted the d-band center of the metals in the MOF closer to the Fermi level, enhancing the material's electron-donating capability. A series of characterization and kinetic simulation results demonstrated that the adsorption mechanism of F − by Ce/Zr/La-MSD involves electrostatic interactions, complexation effects, ion exchange and hydrogen bonding. The primary adsorption sites for PFBA, PFBS, PFOS, and PFHxS were the quaternary ammonium groups containing three carbon atoms, whereas the primary adsorption sites for PFOA and PFHxA were the C 18 chains on DTSACL. In summary, this study provides new insights for the rational design of multifunctional adsorbents and the interpretation of their mechanisms.

Optn loss causes severe bone defects. • OPTN is vital for craniofacial bone development and OMSC osteogenesis. • OPTN cooperates with TRIP6 to recruit F-actin for mitophagy closure. • Actin-driven mitophagy dictates ACP packaging and EV-mediated release. The development of craniofacial bones is highly dependent on the intramembranous ossification process driven by orofacial mesenchymal stem cells (OMSCs). Optineurin (OPTN), a traditional mitophagy receptor, promotes OMSC matrix mineralization by mediating the extracellular release of amorphous calcium phosphate (ACP) through the initiation of mitophagy via liquid-liquid phase separation. However, the dynamic mechanisms by which OPTN regulates mitochondrial engulfment remain elusive. In this work, we show that in both zebrafish and mouse models, Optn absence causes systemic bone loss and craniofacial abnormalities. Mechanistically, OPTN recruits thyroid receptor-interacting protein 6 (TRIP6) to the surface of damaged mitochondria, inducing local F-actin polymerization and remodeling, which relies on cytoskeletal mechanical forces to support the bending and closure of the phagophore. The depletion of OPTN or TRIP6 significantly impairs mitophagy flux, triggering a massive accumulation of dysfunctional mitochondria. Overall, this study elucidates that the OPTN-TRIP6-F-actin axis ensures autophagosome closure through cytoskeletal remodeling, revealing a novel paradigm in which cytoskeletal mechanical regulation maintains mitochondrial homeostasis to orchestrate craniofacial osteogenesis.

A systematic comparison of F − /OH − modified [B 3 O 6 ] 3- clusters shows that properties evolve with F − /OH − content. • By changing the type and arrangement of the fundamental building blocks, a breakthrough in dimensionality was achieved. • Tunable optical properties were achieved, namely, the birefringence across the series ranges from 0.013 to 0.112 at 546 nm. Borates stand out as a prominent class of compounds in structural chemistry, acclaimed for their extraordinary structural diversity stemming from the versatile B–O fundamental building blocks (FBBs), and terminal oxygen modification has emerged as a powerful and effective strategy for tailoring their structures and optimizing functional properties. Herein, we report the synthesis of seven novel hydroxyfluorooxoborates with different dimensional framework via F − /OH − terminal modification of the isolated [B 3 O 6 ] 3- cluster, aiming to explore structural diversity and structure-property relationships. These compounds are classified by their FBBs: Compounds I-IV (A 7 [B 3 O 3 F 4 OH] 2 (PF 6 ) 3 , A = Rb, K, Cs, NH 4 ) with [B 3 O 3 F 4 (OH)] 2- ; Compounds V-VI (Cs 1.2 (NH 4 ) 0.8 [B 3 O 3 F 2 (OH) 2 ] 2 and Rb 1.7 K 0.3 [B 3 O 3 F 2 (OH) 2 ] 2 ) with [B 3 O 3 F 2 (OH) 2 ] - ; and Compound VII (Rb 7 [B 3 O 3 F 2 (OH) 2 ] 2 [B 3 O 3 F 4 (OH)](NO 3 ) 2 BF 4 ) with coexisting [B 3 O 3 F 4 (OH)] 2- and [B 3 O 3 F 2 (OH) 2 ] - . The birefringence across the series ranges from small (∼0.013 - 0.024 at 546 nm for I-IV) and moderate (∼0.051 at 546 nm for VII) to large (∼0.063 - 0.112 at 546 nm for V and VI). Structural and properties analyses reveal that F − /OH − substitution eliminates B–O dangling bonds of [B 3 O 6 ] 3- , leading to varied [B 3 O 3 F 2x (OH) 3−x ] (x = 1, 2, 3) and [B 3 O 3 (OH) x ] (x = 3, 4, 5, 6), featuring a distinct structure-property relationship. In the [B 3 O 3 (OH) x ] series, both polarizability anisotropy and band gap decrease with rising hydroxyl content, while hyperpolarizability increases. In contrast, the mixed F − /OH − series exhibit the opposite trend. In conclusion, this work significantly provides a rational synthetic strategy for tailoring FBBs and constructs deep-ultraviolet hydroxyfluorooxoborates with tunable optical performance. Through F − /OH − terminal modification of [B 3 O 6 ] clusters, a structural breakthrough from 0D clusters to a 2D layer was achieved, along with tunable optical properties.

The electrocatalytic CO 2 reduction reaction to CO (ECO 2 RR) is an effective way to achieve carbon resource utilization. It requires catalysts that can synergistically couple CO 2 activation with efficient CO desorption. This work engineers this synergy by constructing an interfacial Ag δ+ -O-Zn configuration on Zn(OH)F-derived supports via controlled Ag loading (0–5 wt%). The optimal catalyst (3A/Z, 3 wt% Ag) balances the formation of interfacial, oxidized Ag species (Ag δ+ ) with well-dispersed metallic Ag 0 nanoparticles. It achieves a CO Faradaic efficiency of 95.4% at −1.15 V vs. RHE and maintains 86% efficiency over 5 h at 6.38 mA cm −2 . In-situ ATR-SEIRAS spectra and kinetics reveal that Ag δ+ -related sites lower the barrier for *COOH formation, while adjacent Ag 0 domains facilitate *CO desorption. Excessive loading (5A/Z) promotes Ag aggregation and support decomposition, diminishing the critical Ag δ+ -O-Zn interface and performance. This study highlights interface coordination engineering as a key strategy for designing bifunctional ECO 2 RR catalysts.

The development of renewable energy technologies requires effective energy storage devices. Supercapacitors are promising energy storage devices that have attracted considerable attention from researchers due to their fast charging and discharging rates. In this study, V2O5 and f-CNT integrated V2O5 composites (f-CNT/V2O5) were synthesized and studied for electrochemical capacitors' application. While the V2O5 was synthesised using a hydrothermal process. The f-CNT integrated V2O5 (f-CNT/V2O5) composites at various percentages of f-CNT were synthesized using a wet impregnation process. The specific capacitance obtained for V2O5 nanoparticles was 20.78 F.g-1 at 0.1 A.g-1, but f-CNT integrated V2O5 composites showed enhanced specific capacitance of 66.58, 140.94 and 73.15 F.g-1 at 0.1 A.g-1 for f-CNT/V2O5 (10:90), f-CNT/V2O5 (20:80) and f-CNT/V2O5 (30:70) composite, respectively. These results confirmed the enhancement in the supercapacitive performance of V2O5 due to the integration of f-CNT into it. The f-CNT facilitates electron transfer through enhanced conductivity and promote redox reactions through an increased electrode surface area. The best performing f-CNT/V2O5 composite (f-CNT/V2O5 (20:80)) electrode was used to assemble an asymmetrical supercapacitor cell. The f-CNT/V2O5//C device shows a specific capacitance of 261.1 F.g-1 at 1 A.g-1, and 81.8 % of coulombic efficiency for 5000 cycles at 4 A.g-1. Additionally, the assembled device shows a characteristic energy density (52.2 Wh.kg-1) and power density (2400 W.kg-1), which is better than many similar devices.

The implementation of liquid organic hydrogen carriers (LOHCs) is constrained by the high energy consumption and strong dependence on precious‑metal catalysts in conventional thermal processes. This work develops a fluorine-doped Mo-Ni-F/NF bifunctional electrode through a simple electrochemical deposition-sintering method for efficient electrochemical hydrogen storage using quinoxaline under ambient conditions. XRD and TEM characterization revealed a unique structure comprising a MoNi₄ shell with embedded Ni nanoparticles, while SEM and EDS mapping confirmed uniform fluoride distribution and enhanced surface morphology. XPS analysis indicated that fluoride modification improved surface characteristics without altering chemical states. The catalyst demonstrates exceptional performance in reversible quinoxaline hydrogenation (92.1 % conversion after 5 h, 95.6 % FE) and dehydrogenation (100 % conversion after 4 h, 97.2 % FE). DFT calculations showed that electron transfer between MoNi₄ and nickel nanoparticles enhanced catalytic activity, while fluorine modulation reduced the adsorption energy of quinoxaline on nickel (111) from −2.84 eV to −0.55 eV, and tetrahydroquinoxaline from −2.08 eV to −0.84 eV, mitigating catalyst poisoning. In situ Raman spectroscopy identified dynamically formed NiOOH as the active phase, which facilitates proton-coupled dehydrogenation via -OH/μ-O-Ni intermediates. This work provides novel catalytic materials and mechanistic insights for the development of low-cost, room-temperature, and highly effective electrochemical LOHC systems.

Urea is a key biomarker for diagnosing various kidney and liver disorders, which can be assessed through sensing platforms. However, existing urea sensors have performance issues in real samples. Herein, a novel fiber-organic electrochemical transistor (F-OECT) sensing platform was constructed by sequentially depositing cobalt-based metal-organic framework material (ZIF-67), carboxylated multi-walled carbon nanotubes, poly (3,4-ethylenedioxythiophene), and urease on cotton fibers for urea determination. The resulting F-OECT sensor exhibited excellent performance toward urea detection with a high sensitivity (82.91 μA/decade). This performance is attributed to the synergistic effect of the hierarchical composite: the significantly enlarged electrochemically active surface area of PEDOT/f-MWCNT/ZIF-67 facilitates high-density urease immobilization, while the conductive network ensures efficient signal transduction, coupled with the intrinsic signal amplification of the OECT architecture. Under optimized conditions, the F-OECT sensor illustrated a wide linear response range (1 pM-10 mM) and a low detection limit of 1 pM toward the detection of urea, coupled with an excellent selectivity, reproducibility, and stability. More importantly, the F-OECT sensor was able to detect urea in real sweat and urine samples. Based on these encouraging data, the F-OECT sensor was connected to a printed circuit board to transmit signals via Bluetooth, and the results showed a sensor capable of visually quantifying urea. Overall, the proposed F-OECT sensor looks promising for future non-invasive and sensitive liquid detection of urea, thereby deserving further research and development.
