O3-type Ni/Mn-based transition metal oxides have garnered significant interest as cathode materials for sodium-ion batteries (SIBs) due to their high specific capacity and abundant resources. However, their commercialization application has been impeded by rapid capacity fading owing to structural degradation, gas evolution, irreversible phase transitions during charge/discharge cycling. Herein, The Zr 4 + /F - dual-doped strategy is developed to boost the Na-storage performance of Ni/Mn-based O3-NaNi 0.3 Fe 0.1 Mn 0.47 Cu 0.1 Zr 0.03 O 2-x F x (NFMCZF-x) layered oxide cathode material prepared by high temperature calcination method. Structural and electrochemical analyses reveal that Zr⁴⁺ doping expands Na⁺-layer spacing and F⁻ doping strengthens transition metal-oxygen bonds. These synergistic effects of Zr 4+ /F - dual-doping is benefit to suppressing O3↔P3 phase transitions, Jahn-Teller distortion and irreversible oxygen redox. Thus, the optimized NFMCZF-0.03 cathode delivers high specific capacity (178 mAh g −1 at 0.1 C) and excellent cycling stability (72 % capacity retention after 100 cycles at 1.0 C). This study establishes dual doping as an effective strategy for developing Ni/Mn-based layered oxide as high-performance cathodes for SIBs.

For practical applications of microbial fuel cells (MFCs), 5H-dibenz [b,f] azepine-5-carboxamide (Carbamazepine, CBZ) was used as the organic precursor for the synthesis of catalysts composed of Fe–N–C complexes (named as Fe-CBZ-Cats) through a sacrificial support method. Characterizations by SEM, XPS and TEM-EDS elemental mapping show that the synthesized Fe-CBZ-Cats have porous structure and uniformly dispersed Fe/N/C complex centers which could play key roles in effective ORR . Linear scanning voltammetry (LSV) measurements show that the synthesized Fe-CBZ-Cats exhibits ORR activity comparable to commercial Pt/C catalysts under the same catalyst loading (2 mg cm −2 ). The maximum power density produced by cathode-limiting MFCs with Fe-CBZ-Cats air cathodes was 431 ± 23 μW cm −2 , higher than those in the control MFCs with Pt/C air cathodes (403 ± 13 μW cm −2 ) and activated carbon air cathodes (296 ± 24 μW cm −2 ). In addition, the toxicity tolerance of the synthesized Fe-CBZ-Cats is much higher than Pt/C.

The threshold voltage and mobility of organic thin-film transistors (OTFTs) are influenced not only by the dielectric constant of the insulating layer but also by the crystallinity at the interface between the semiconductor and the insulating layer. The crystallization of 2,9-didecyldinaphtho[2,3-b:2′,3′-f]thieno[3,2-b]thiophene (C10-DNTT) is driven by molecular fastening effects from its long alkyl chains and π–π* stacking interactions. This work proposes a method utilizing the interaction of interfacial functional groups to create nucleation centers for C10-DNTT, thus reducing grain boundaries. We synthesized the homopolymer poly(4-(1,3-dithia-2thioxocyclopentyl) methacrylate) (P(TCMA)), which possesses side chains with high dipole moment thiocarbonate groups, and the copolymer poly(4-(1,3-dithia-2thioxocyclopentyl) methacrylate-co-10-([1,1’:4′,1″-terphenyl]-3-yloxy) decyl methacrylate) (P(TCMA-co-10TPOMA)), which contains decyloxytriphenyl groups in its side chains. The mobility of OTFT devices increased from 0.84 cm2 V–1 s–1 with cured P(TCMA) as the insulating layer to 2.97 cm2 V–1 s–1 with cured P(TCMA-co-10TPOMA)-5, reaching a maximum of 3.40 cm2 V–1 s–1 when P(TCMA-co-10TPOMA)-15 was used as the insulating layer, making it a promising candidate for direct application in drive units.

An optimization method of NBD-F derivatization has been developed for the determination of proline in honey using high performance liquid chromatography (HPLC) with fluorescence detection. To determine the free proline in different samples of honey, ultrasound extraction was performed using 0.1 M borate buffer solution as the extraction solvent. Chromatographic separation was performed on a XDB C18 column (150 × 4.6 mm i.d.) using 0.1 M sodium acetate buffer solution (pH 7.2) : methanol : tetrahydrofuran (900 : 95 : 5, respectively, v/v/v) as mobile phase A and methanol as mobile phase B at a flow rate of 1.0 mL min−1 with a run time of 10 min. The assay was linear over a range of 0.15 μg mL−1 to 100.00 μg mL−1 with a lower limit of detection of 3.00 mg kg−1, and recoveries were greater than 90%. The intra-day and inter-day precision was less than 4%. This method was successful in determining free proline in honey, ranging from 80.5 mg kg−1 to 426.4 mg kg−1 in different honey samples.

Chlorogenic acids are important phenolics in the fruits of wolfberry, but little attention has been paid on their glucosylated forms. In the present study, a glucosylated form of chlorogenic acid was isolated from the fruits of Lycium barbarum L. var. auranticarpum K. F. Ching (also called yellow wolfberry) and identified to be (-)-5- O -(3- O -β- d -glucopyranosylcaffeoyl)-quinic acid (5-CQA-3′βG) by high resolution mass spectrometry and nuclear magnetic resonance spectrometry. The content of 5-CQA-3′βG in the dried fruit was determined as 0.0293 ± 0.0015% by HPLC. In addition, 5-CQA-3′βG showed a good scavenging capacity for 2,2′-azino-bis-(3-ethylben-zothiazoline-6-sulphonate) free radicals but had a relatively low reducing power and scavenging capacity for 2,2-diphenyl-1-picrylhydrazyl free radical. Moreover, the secretion of nitric oxide, tumor necrosis factor-α and interleukin-6 as well as related mRNA expression were reduced in lipopolysaccharide-stimulated RAW264.7 macrophage cells treated with 5-CQA-3′βG. This is the first report describing purification, identification and bioactivity of glucosylated CQA from yellow wolfberry.

Environmental safety monitoring has significantly benefited from the incorporation of gas sensors. Given the pernicious effects of ammonia and acetic acid gases on the environment and human health, it is imperative to develop a room temperature dual-functional gas sensor capable of simultaneously detecting both these gases. In this research endeavor, acid-functionalized multi-walled carbon nanotubes (f-MWCNTs) were integrated with Bi 2 S 3 through a hydrothermal approach, leading to the fabrication of a Bi 2 S 3 /f-MWCNTs-2 nanocomposite-based chemoresistive gas sensor. The results demonstrate that the Bi 2 S 3 /f-MWCNTs-2 sensor exhibits a response value of 52.7 % towards 100 ppm NH 3 at room temperature (25℃), displaying a declining resistance curve upon exposure to the target gas. Similarly, for 100 ppm CH 3 COOH under ambient conditions (25℃), the sensor records a response value of 72.55 %, accompanied by a rising resistance curve when in contact with CH 3 COOH gas. The distinctive feature of this dual-functional sensor lies in its ability to detect opposing transient response curves for the two gases, which is crucial for distinguishing between different gases. Furthermore, the sensor boasts swift response recovery, excellent repeatability, and robust stability. This study underscores the promising potential of the Bi 2 S 3 /f-MWCNTs-2 nanocomposite sensor in applications such as environmental monitoring.

Two essential oils were isolated from discarded perfume lemon and leaves (Citrus limon (L.) Burm. F.) by hydro-distillation with good yield (0.044% for perfume lemon and 0.338% for leaves). Their biological activities were evaluated against five selected bacterial strains and Aedes albopictus (Ae. albopictus, Diptera: Culicidae). Chemical composition indicated that both essential oils were rich in essential phytochemicals including hydrocarbons, monoterpenes and sesquiterpene. These constituents revealed some variability among the oils displaying interesting chemotypes (R)-(+)-limonene (12.29–49.63%), citronellal (5.37–78.70%) and citronellol (2.98–7.18%). The biological assessments proved that the two essential oils had similar effect against bacterial (inhibition zones diameter ranging from 7.27 ± 0.06 to 10.37 ± 0.15 mm; MICs and MBCs ranging from 1.6 to 6.4 mg/mL); against Ae. albopictus larvae (LC50 ranging from 384.81 to 395.09 ppm) and adult mosquito (LD50 ranging from 133.059 to 218.962 μg/cm2); the activity of the two chemotypes ((R)-(+)-limonene and citronellal): larvae (LC50 ranging from 267.08 to 295.28 ppm), which were all presented in dose-dependent manners. Through this work, we have showcased that recycling and reusing of agriculture by-products, such as discarded perfume lemon and leaves can produce eco-friendly alternatives in bacterial disinfectants and mosquito control product.

BACKGROUND Pectin extracted by high-speed shearing from passion fruit peel (HSSP) is a potentially excellent wall material for encapsulating curcumin, which has multiple advantages over pectin prepared by heated water extraction. HSSP was used to fabricate complex nanoparticles of zein–sodium caseinate–pectin for encapsulation of curcumin in this study. The influence of heating on the physicochemical properties of the composite nanoparticles was also investigated, as well as the effect of composite nanoparticles on the encapsulation efficiency, antioxidant activity and release characteristics of curcumin. RESULTS The nanoparticles were formed through electrostatic interactions, hydrogen bonds and hydrophobic interactions between the proteins and HSSP. A temperature of 50 °C was more favorable for generating compact and small-sized nanoparticles, which could effectively improve the encapsulation efficiency and functional properties. Moreover, compared to other pectin used in the study, the nanoparticles prepared with HSSP showed the best functionality with a particle size of 234.28 ± 0.85 nm, encapsulation rate of 90.22 ± 0.54%, free radical scavenging rate of 78.97% and strongest protective capacity in simulated gastric fluid and intestinal release effect. CONCLUSION Zein–sodium caseinate–HSSP is effective for encapsulating and delivering hydrophobic bioactive substances such as curcumin, which has potential applications in the functional food and pharmaceutical industries. © 2024 Society of Chemical Industry.

BACKGROUND 2-Amino-3-methylimidazo[4,5- f ]quinoline (IQ), a typical heterocyclic amine, is a common dietary carcinogen raising gastric and colorectal cancer risks. As an abundant anthocyanin monomer with established antioxidant and anti-inflammatory activities, cyanidin-3- O -glucoside (C3G) might attenuate IQ toxicity. Nevertheless, whether and how C3G alleviates IQ-triggered gastrointestinal damage remains unclarified. This study investigated the protective mechanisms of C3G against IQ-induced gastrointestinal injury in mice using biochemical assays, histopathology, western blotting, 16S rRNA sequencing, and molecular simulation. RESULTS The results demonstrated that C3G significantly ameliorated IQ-induced gastric and colonic tissue damage. It effectively reduced key inflammatory markers (nitric oxide, interleukin-6, and tumor necrosis factor-α) and the oxidative stress marker MDA in repaired mouse tissues and serum, while elevating antioxidant enzyme levels. Western blot analysis revealed tissue-specific protective mechanisms. In gastric tissue, C3G activated the Keap1-Nrf2 pathway to enhance antioxidant capacity and suppressed the NF-κB pathway to attenuate inflammation. In the colon, C3G inhibited inflammation via MyD88/TLR4/NF-κB signaling and upregulated the expression of tight junction proteins to restore intestinal barrier function. Gut microbiota analysis revealed that C3G reversed IQ-induced dysbiosis and increased the relative abundance of beneficial bacteria such as Roseburia and Enterorhabdus . Molecular dynamics simulations demonstrated that C3G could enhance IKKβ stability and interfere with its phosphorylation by forming hydrogen bonds with residues ASP151 and ASP109. CONCLUSION This study elucidates that C3G alleviates IQ-induced gastrointestinal injury through a multidimensional mechanism involving microbiota modulation, antioxidation, anti-inflammation, and intestinal barrier repair, providing a theoretical basis for anthocyanin-based dietary interventions against heterocyclic amine toxicity. © 2026 Society of Chemical Industry.

The investigation of birefringent materials is predominantly focused on π-conjugated systems; however, a large band gap or deep ultraviolet (DUV) transmittance cannot be guaranteed. In this work, we propose an extended π-conjugated strategy to increase the birefringence while keeping the large band gap. In the scheme, two new fluoroaluminoborates, BaAlB3O6F2 and BaAl2(B3O6)2F2, are synthesized by combining the [BO3] group with the [AlO4F2] group and the [B3O6] group with the [AlO3F] group through a rational structural design. The experimental results indicate that both BaAlB3O6F2 and BaAl2(B3O6)2F2 exhibit shorter UV cutoff wavelengths (<200 nm) and larger birefringence (Δn > 0.07@546 nm). Notably, this is a new finding in the Ba–Al–B–O–F system since the discovery of the well-known nonlinear optical crystal BaAlBO3F2. In comparison with BaAlBO3F2, BaAlB3O6F2 and BaAl2(B3O6)2F2 exhibit a markedly elevated birefringence (0.0418 vs. 0.087/0.105 at 546 nm). Furthermore, BaAl2(B3O6)2F2 exhibits the largest band gap (7.87 eV) of all known F-containing aluminoborates. This work not only identifies two potential DUV birefringent materials, but also proposes a novel design approach for reconciling the conflicting properties between birefringence and bandgap.

LiFePO 4 has become a mainstream cathode material, owing to its good safety and low price. However, its intrinsic limitations in terms of electronic and ionic conductivities hinder its further advancements. To overcome this challenge, element doping has been explored to enhance its conductivity. Here, Na and F co-doped LiFePO 4 /C was successfully synthesized via a carbothermic method. Structural characterization techniques were employed to confirm the formation of Li 0.97 Na 0.03 FePO 3.97 F 0.03 with controllable particle sizes. The incorporation of Na and F ions into the LiFePO 4 lattice results in a reduction of the Li-O bond energy. This decrease in bond energy facilitates the extraction and insertion of lithium ions during the charge and discharge processes, subsequently improving the overall kinetics of lithium-ion diffusion. Simultaneously, lattice distortion induced by doping led to charge compensation and accelerated Li + migration. Benefiting from the enhancement of intrinsic conductivity and Li + diffusivity, the specific capacitance of the co-doped LiFePO 4 /C cathode material was found to be 160 and 110 mAh g −1 at 0.1 and 5 C, respectively. Further, density functional theory calculations showed that Na/F co-doping enhanced the structural evolution in the material and increased free carrier concentration in LiFePO 4 . This work demonstrates that synergistic Na and F co-doping can optimize the rate performance of LiFePO 4 by enhancing intrinsic conductivity and Li + diffusivity, suggesting promising applications of the co-doped LiFePO 4 /C in high-power lithium-ion batteries for electric vehicles and grid-level energy storage systems.

Bisphenol S (BPS) and Bisphenol F (BPF), as alternatives to bisphenol A (BPA), are recognized for their endocrine-disrupting properties, but their combined immune toxicity mechanisms remain poorly understood. This study systematically evaluates the individual and joint immune toxicity effects of BPS and BPF through ADMET predictions, transgenic zebrafish models, and molecular docking analyses. The results indicate that equal effect concentration BPS and BPF act through distinct immune pathways: BPS primarily targets macrophages to mediate immune responses, while BPF significantly stimulates neutrophil proliferation and induces a stronger inflammatory response through chemokine signaling. Molecular docking studies show that BPF binds more stably to pro-apoptotic protein Mapk8 and oxidative stress-related protein Hsp90aa1, leading to significantly higher levels of apoptosis and reactive oxygen species (ROS) compared to BPS. The similarity of modes of action (MOA)between BPS and BPF based on relevant immune indicators calculated and experimentally is about 0.3; this quantitative result also proves that modes of action differ widely. Nonetheless, most of the indicators showed superimposed effects in the combined experiments, and it is noteworthy that the oxidative stress indicators (SOD, MDA) showed synergistic effects, suggesting that BPS and BPF, which have very different modes of action, are able to be risk assessed using an additive model with respect to immunity, but may exhibit synergistic risks with respect to oxidative stress. This research demonstrates that BPS and BPF induce immune toxicity via different molecular targets and pathways and highlights the need to account for their synergistic effects in risk assessments. These findings provide important insights into the immune toxicity mechanisms of BPA substitutes and the potential risks of combined exposures.
