This study developed an innovative colorimetric film by incorporating 1-butyl-3-methylimidazolium chloride (BmimCl) in a composite matrix containing red cabbage anthocyanins extract (RCAE), ferulic acid (FA), gellan gum (GG), and potato starch (PS) for real-time grass carp freshness detection. A comprehensive analysis was conducted on the rheological characteristics of film-forming solutions, mechanical properties, hydrophobicity, opacity, characterization of structure, sensitivity, and color stability of smart film. Significantly, the introduction of BmimCl led to multifaceted enhancements in film performance. The findings indicated that the flexibility of films added with BmimCl was enhanced and the elongation at break (EAB) was increased from 20.34 % to 28.36 %. The surface of films was smoother and denser, and the surface roughness was reduced from 1.7 μm to 1.2 μm. The peak intensities of the XRD and FT-IR patterns of films changed, indicating the formation of hydrogen bonds between BmimCl and film substrates. The GGPS-R-FA-B4 film presented the most pronounced color change in different pH environments and the most sensitive response to the variation of ammonia concentration in the environment. The color of GGPS-R-FA-B4 film exhibited a strong correlation with the quality change of fish, which could be used to distinguish the freshness, sub-freshness, and spoilage of grass carp. This study provided an effective method to enhance the accuracy and sensitivity of smart films for monitoring food freshness.

Photocatalytic three-electron oxygen reduction (3e - ORR) can convert dissolved O 2 into •OH via coupled 2e - /1e - steps, bypassing external H 2 O 2 dosing and the kinetic bottleneck of conventional photo-self-Fenton (PSF) systems. Here, Fe-substituted phosphomolybdate clusters (FePMo) are anchored on a biomass-derived hierarchical tubular carbon (HTCC) to form an HTCC/FePMo heterojunction (HFe) that drives a visible-light self-Fenton process. For tetracycline (TC, 10 mg L −1 ), HFe achieves 99 % removal within 120 min at unadjusted pH 0 = 5.8 ( k obs = 0.026 min −1 ) and 3.6–7.7-fold higher mineralization than either component, while retaining high activity from pH 3–9 and in saline water, natural surface water, and secondary effluent. In a continuous-flow reactor, an HFe/PVDF membrane (0.64 mg cm −2 loading; 2 mL min −1 , HRT 1.23 min) sustains > 90 % TC removal for 120 h. Ecotoxicity is alleviated, with inhibition-zone diameters shrinking from ∼2.3 to ∼0.8 cm ( S. aureus ) and from ∼1.25 to ∼0.7 cm ( E. coli ), and wheat-leaf Fv/Fm recovering to ∼0.73, comparable to the water control. The energy demand is low (EE/O = 0.0031 kWh L −1 ; EE/M = 0.31 kWh g −1 ), supporting a scalable, sustainable route for advanced treatment of refractory wastewater.

A new binary mixture system of ionic liquid 1–ethyl–3–methylimidazolium acetate ([Emim][Ac]) and methyldiethanolamine (MDEA) (IL + alkanolamine) were prepared. The physico–chemical properties of density, viscosity , electrical conductivity , and refractive index for the mixtures were determined from 288.15 K to 353.15 K. By the Vogel–Fulcher–Tamman (VFT) equation and Arrhenius equation , the temperature dependences of the viscosities and electric conductivities for the system were graphically described and the VFT equation showed better correlation for the system. To investigate the internal interactions of the mixtures, the excess volume and DFT calculations were employed. The trend of excess molar volumes showed more efficient packing structures due to the increase of interactions in the mixed system with the increasing of temperature. Further, the structures, the energetics , and charge distribution of all ions and molecules involved in interactions were estimated by DFT calculations combining the COSMO–RS methodology to describe intermolecular interactions between the [Emim][Ac] and MDEA.

NASICON structured Li 1.3 Al 0.3 Ti 1.7 (PO 4 ) 3 (LATP) has attracted widespread attention due to its simple preparation and excellent stability towards water and air. However, there are many problems such as high interfacial resistance between electrolyte and electrodes as well as low ionic conductivity of LATP. In this paper, the effect of F doping on Li ion diffusion channel in electrolyte was investigated in detail by density functional theory (DFT) calculation. The results show that F doping can effectively reduce the formation energy of Li vacancy. Meanwhile, it can also reduce the diffusion energy barrier and induce the high-energy Li ions at 36f site to carry out synergistic diffusion via various ways at the same time. Then, the F-doped LATP electrolyte was prepared successfully. Its ionic conductivity is as high as 0.358 mS cm −1 at room temperature . At the same time, the solid-state lithium metal batteries with F-doped LATP electrolyte shows a high capacity of 136.2 mA h g −1 at 0.5C and excellent cyclability for 200 cycles. These results demonstrate that F doping may be an effective way to improve the performance of LATP electrolyte.

A novel barium zinc borate contains π-conjugated [B3O6]3– anions and [B6O12]6– anion with edge-sharing BO4 tetrahedra, Ba6Zn6(B3O6)6(B6O12), has been successfully synthesized via a high-temperature solution reaction. In its structure, the isolated planar π-conjugated B3O6 groups are interconnected by ZnO4 tetrahedra via corner sharing to construct a [Zn3(B3O6)3]3– single layer parallel to the ab plane with the large Zn3B6 9-member rings. Two adjacent [Zn3(B3O6)3]3– single layers are interconnected by [B6O12]6– anions into a two-dimensional [Zn6(B3O6)6(B6O12)]12– double layer with 1D tunnels of Zn4B8 12-member rings along the a-axis. Neighboring such double layers are packed in an A–B–A–B... fashion along the c axis, and the Ba2+ ions act as counterbalance cations filling in the voids of double layers. All of the planar π-conjugated [B3O6]3– groups in Ba6Zn6(B3O6)6(B6O12) are in approximately parallel arrangement, producing large optical anisotropy and birefringence. The UV–vis–NIR absorption spectrum manifests that the UV cutoff edge for the title compound is below 200 nm. Ba6Zn6(B3O6)6(B6O12) possesses the largest birefringence (0.115@1064 nm) among the zincoborates reported. Its thermal stability, infrared spectrum, and theoretical calculations were also performed.

A noncentrosymmetric adduct, SbI3·(S8)3, is obtained by a facile solution method. It crystallizes in the trigonal space group R3m, and its structure features van der Waals force connected, isolated trigonal-pyramidal SbI3 and chairlike S8 units. SbI3·(S8)3 exhibits strong second-harmonic-generation responses around 4 times that of KH2PO4 (1.064 μm) and 1 times that of AgGaS2 (AGS; 2.1 μm) at 210–250 μm, respectively. Under both laser-radiation wavelengths, it exhibits type I phase-matching behavior. Its laser-induced damage threshold is measured to be around 26 times that of AGS under 1.064 μm. To better understand these optical data, theoretical calculations are performed to address its electronic structure and optical properties.

Liquid–liquid phase equilibria of binary solutions of the room temperature ionic liquid (RTIL) 1-methyl-3-octylimidazolium tetrafluoroborate ([C 8 mim][BF 4 ]) with 1-heptanol or 2-pentanol were measured. The critical exponents β obtained from the liquid–liquid equilibrium data in the critical region were consistent with the 3D-Ising value, which confirmed the 3D-Ising criticality of the investigated binary ionic solutions. The asymmetry of the diameters of the coexistence curves was analyzed by the complete scaling theory, indicating a significant contribution of the heat capacity related term. The RPM (restricted primitive model)-rescaled critical parameters were calculated, which showed dual characters of both solvophobic and coulombic criticalities of the studied binary ionic solutions.

Epithelial-mesenchymal transition (EMT) is a key driver of colorectal cancer (CRC) metastasis, contributing significantly to the high mortality rate in CRC patients. Bone marrow tyrosine kinase on chromosome X (BMX), a non-receptor tyrosine kinase, is broadly expressed in bone marrow epithelial cells, hematopoietic cells, and endothelial cells. While BMX has been implicated as an oncogenic factor in multiple malignancies, its functional role in CRC remains poorly understood. In this study, we demonstrated that BMX expression was significantly upregulated in CRC tissues. Genetic silencing of BMX by siRNA or pharmacological inhibition with BMX-IN-1 markedly attenuated the proliferation, migration, and invasion capacity of CRC cells. Consistently, BMX knockdown or inhibition potently suppressed tumor growth in cell line-derived xenograft models. Mechanically, β-catenin directly binds to the BMX promoter region, transcriptionally activating BMX expression. Furthermore, BMX physically interacts with signal transducer and activator of transcription 3 (STAT3) and enhances its phosphorylation at the Y705 residue, facilitating nuclear translocation of p-STAT3. Notably, nuclear p-STAT3 binds to E-cadherin promoter to suppress its transcription, thereby promoting EMT. Critically, the STAT3 inhibitor S3I-201 abrogated the pro-tumorigenic effects of BMX overexpression on HT29 cell proliferation, migration, and invasion. In conclusion, our findings establish that BMX drives CRC progression by activating STAT3 signaling pathway, which subsequently suppresses E-cadherin expression to induce EMT.

CsPbX 3 (X = I, Br, Cl) perovskite quantum dots (QDs) have shown great potential in optoelectronic devices due to their wide tunable bandgap, high photoluminescence quantum yield, and narrow emission spectra. Currently, methods for regulating blue light emission through component engineering or dimensional engineering suffer from issues such as halogen phase separation and increased defects, making it difficult to meet the strict requirements of display technology for pure blue light (CIE y < 0.15). Additionally, traditional synthesis processes are complex and have poor compatibility with Micro-LED miniaturization technology, which restricts their industrial application. Therefore, this study proposes an efficient and green spray drying method. By dissolving the perovskite precursors and halide salts in an aqueous solution, CsPb(Cl/Br) 3 QDs can be rapidly (<10 s) synthesized without organic solvents, and continuous tuning from green to blue light is achieved. This method effectively suppresses surface defects and phase separation through Cl element encapsulation, significantly enhancing stability.Moreover, its excellent processability supports spraying and film formation on any substrate, enabling the direct preparation of highly uniform Mini/Micro-LED pixel units. This technology provides a new approach for large-scale, low-cost manufacturing of perovskite QDs and is expected to accelerate the commercialization process of next-generation display technologies.

LiTi2(PO4)3 (LTP) is widely recognized as a promising anode material for aqueous lithium-ion batteries due to its stable three-dimensional framework structure and working potential within the aqueous electrolyte potential window. However, the low conductivity of pure-phase LTP poses a significant challenge that must be overcome for its practical application. In this work, N-doped carbon-coated LTP (NC@LTP) composites with a layered flower-like morphology were synthesized via an organic precipitation method. The N-doped carbon layer improved the conductivity and hydrophilicity of the anode and caused carbon defects that facilitated Li+ transport. The initial specific capacity at 10 C was enhanced from 39.4 to 81.5 mAh g–1 after N-doping. The pouch cells retained 92.7% of their capacity after 150 cycles at 1 C and demonstrated excellent safety in abuse tests. In addition, the modification mechanism of the N-doped carbon layer was verified through DFT calculations. This study provides references and ideas for the modification of high-performance aqueous lithium-ion battery electrode materials.

Fluoride compounds are abundant and widely distributed in the environment at various concentrations, which can seriously injure the human body. In this study, we aim to evaluate the effects of excessive fluoride exposure on the liver, kidney, and heart tissues of healthy female Xenopus laevis by administering NaF (0, 100, and 200 mg/L) in drinking water for 90 days. The expression level of procaspase-8, cleaved-caspase-8, and procaspase-3 proteins were determined by Western blot . Compared with the control group, the group exposed to NaF exhibited expression levels of procaspase-8, cleaved-caspase-8, and procaspase-3 proteins that were considerably upregulated at a concentration of 200 mg/L in the liver and kidney. The cleaved-caspase-8 protein expression in the group exposed to a high concentration of NaF was lower than that in the control group in heart. Histopathological results by hematoxylin and eosin staining showed that excessive NaF exposure caused necrosis of hepatocytes and vacuolization degeneration. Granular degeneration and necrosis in renal tubular epithelial cells were also observed. Moreover, hypertrophy of myocardial cells, atrophy of myocardial fibers and disorder of myocardial fibers were detected. These results demonstrated that NaF-induced apoptosis and the mediated death receptor pathway activation ultimately damaged the liver and kidney tissues. This finding offers a fresh perspective on the effects of F-induced apoptosis in X. laevis.

Aurivillius phases with narrow band gaps have attracted extensive interest in the field of photocatalysis, however, they exhibit poor activity due to the low utilization of photogenerated carriers. Herein, a series of S-scheme C3N4@Bi m+1 Fe m-3 Ti 3 O 3m+3 (m = 4, 5, 6) heterojunctions with two-dimensional structures were synthesized by simple two-step method. Compared with single materials, the composites exhibit excellent photocatalytic tetracycline degradation under visible light, and 91.8% of tetracycline can be degraded accompanied with 81.2% of TOC removal within 120 min over C 3 N 4 @Bi 5 FeTi 3 O 15 . The enhanced photocatalytic performance is due to strong interface interaction, high conductivity, and efficient charge separation ability. The mechanism analysis indicates that the C 3 N 4 @Bi 5 FeTi 3 O 15 heterojunction follows an S-scheme heterojunction mechanism with a strong interfacial internal electric field directed from C 3 N 4 to Bi 5 FeTi 3 O 15 , thus, the photogenerated electrons in Bi 5 FeTi 3 O 15 move toward C 3 N 4 , which retains high oxidation ability of Bi 5 FeTi 3 O 15 and high reduction ability of C 3 N 4 to efficiently produce the reactive species, such as O 2 − · and ·OH.
