Aqueous zinc-ion batteries (AZIBs) have promising for large-scale energy storage due to their low cost and high safety. However, the slow migration rate and strong electrostatic repulsion of Zn 2+ impose stringent requirements on the selection of cathode material. Therefore, the development of suitable cathode materials is crucial for the further advancement of AZIBs, playing a vital role in reducing costs and enhancing electrochemical performance. Vanadium pentoxide (V 2 O 5 ) exhibits potential for energy storage due to its relatively high theoretical specific capacity. This study proposes an in-situ synthesis strategy to directly grow V 2 O 5 nanostructures onto a graphite felt (GF) substrate, constructing a self-supported, binder-free V 2 O 5 @GF composite cathode. The high electrical conductivity of GF serves as a three-dimensional conductive network, effectively promoting electron transfer kinetics between the active material and the electrolyte, and enhancing the structural integrity of the cathode material, thus significantly improving electrochemical cycling stability. As a cathode material for AZIBs, V 2 O 5 @GF demonstrates impressive discharge specific capacity (507 mAh/g at 0.2 A/g), along with outstanding rate capability (165 mAh/g at 5 A/g), and a long-cycling life (86.5% capacity retention after 2000 cycles at 4 A/g). This study provides a new approach and direction for the high-specific-capacity development of AZIBs.

The development of novel nanozymes with high peroxidase-like activity for detecting biological molecules is essential for human health. Herein, iron (III) vanadate (FeVO 4 ) nanoparticles (NPs) were successfully prepared by calcining spinel-like iron (II) vanadate (FeV 2 O 4 ) under the different temperature (T = 550, 650, 750 ℃) (FeVO 4 -Ts) in air. Attributed to the Fenton-like effect and synergistic effect, the peroxidase-like activity of FeVO 4 -600 NPs is much greater than single-metal oxide. Base on the complexation between Fe 3+ and salicylic acid (SA), a sensitive colorimetric sensor for detecting SA was established, which showed outstanding selectivity and interference with the lowest detection limit (LOD) of 0.08 µM to date, to the best our knowledge. This work may broaden the applied range of Fe-based bimetallic oxide in the biological detection field.

As a critical index for heavy metal toxicity, the quantitative detection of silver ions (Ag + ) is essential for health assessment and environmental monitoring. A sensing platform based on composite gold nanoclusters with dual emissions located in the near-infrared (NIR) range has been constructed for highly sensitive Ag + quantification. Dual-emissive glutathione-functionalized gold nanoclusters (GSH-AuNCs) were first synthesized via a one-pot hydrothermal method. Then, the weak NIR emissions were effectively enhanced by introducing thiolated β-cyclodextrin to regulate the surface ligands of clusters and by ZIF-8 encapsulation to allow the spatial nanoconfinement effect. The GSH-AuNCs nanocomposite exhibited dual-channel emission peaked at 610 nm and 810 nm under 437 nm excitation. Compared with the native clusters, the fluorescent emissions were enhanced with total factors of 6.86-fold at 610 nm and 2.32-fold at 810 nm. The sensing nanocomposite can specifically complex with Ag + by the surface thiol groups and β-cyclodextrin cavities on clusters. The interaction between the fluorescent composite and Ag + changed the ligand-to-metal charge transfer (LMCT) of the clusters and caused fluorescence enhancement at 610 nm and quenching at 810 nm. This opposite variation trend in the fluorescence intensities gives the possibility of constructing a ratiometric fluorescent probe for Ag + detection. The dual-emission intensity ratio (F 610 /F 810 ) demonstrates a quantitative relationship with Ag + concentration (C Ag+ ). The sensing system possesses a linear response range of 0.02~5.00 μmol/L in pH 8.5 buffer, achieving a detection limit of 11.6 nmol/L (S/N = 3). Measurement results of real serum and water samples confirmed that the sensing platform had good accuracy and exceptional anti-interference capability for Ag + detection.

Background Rice is a major food crop in China as well as Asia, yet its production is threatened by microbial diseases including blast disease caused by fungal pathogen ( Magnaporthe oryzae ) and bacterial blight caused by several bacterial pathogens. To screen for bacterial microbiota associated with rice blast occurrence, and/or contributing to disease resistance, we performed microbiota analysis with rhizosphere soil, root, stem, and leaf samples of blast susceptible (CO39) and resistant (Y33R) rice grown in a blast disease nursery garden. Results Our result showed no significant difference in microbiota of rhizosphere soil, root, or leaf between these two rice cultivars, but stem microbiota were significantly different. Pantoea spp. were enriched in stem of blast susceptible rice, suggesting that it may play a role after fungal infection. A total of 822 bacterial strains were isolated from the phyllospheric (including leaf and stem) samples of Y33R and CO39 rice. Based on 16S rRNA amplicon sequencing, and phylogenic analysis using 16S rRNA, gyrB , leuS , and rpoB gene sequences, the 3 isolated strains and 1 strain were identified as P. ananatis and P. dispersa , respectively. The strains A25-H1 and B10-A1 were selected for genome sequencing, and based on Average Nucleotide Identity (ANI) analysis, we confirmed that A25-H1 was P. ananatis and B10-A1 was P. dispersa . The P. ananatis consortium (A25-F1, A25-G1, and A25-H1 combination) A25-11 and P. dispersa strain B10-A1 displayed suppressive effect on blast disease when they were applied to the susceptible rice CO39. Although a P. ananatis strain SC7 has been reported to cause bacterial blight in rice, A25-11 or B10-A1 was non-pathogenic to rice under experimental conditions. Furthermore, they could also suppress bacterial blight caused by SC7 or Xanthomonas oryzae pv. oryzae strain Pxo99A. A25-11 and B10-A1 did not affect the growth of M. oryzae mycelia in confrontation culture analysis, but induced transcription of rice immunity genes and promoted ROS accumulation, suggesting that the biocontrol effect of A25-11 or B10-A1 may lie on immunity priming. We further showed that A25-11 and B10-A1 possessed growth promoting capacity including indole 3-acetic acid (IAA) production, phosphate solubilization, nitrogen fixation, and siderophore production. Under field condition, the consortium A25-11 and strain B10-A1 could effectively suppress leaf and panicle blast. Conclusions Overall, this study established a microbiome method for identifying the rice bacterial communities of agricultural significance, with capacity of rice disease management and/or growth promotion.

Semiconductor X-ray detectors have attracted considerable attention recently owing to their high sensitivity and excellent stability. Among them, semi-insulating β-Ga 2 O 3 stands out due to its superior thermal stability, high breakdown electric field, and high crystal quality, enabling the fabrication of high-performance detectors suitable for various working environments. In this study, Ni 2+ was introduced into β-Ga 2 O 3 as a deep-level acceptor via doping engineering. A high-resistivity Ni-doped β-Ga 2 O 3 crystal was grown using the edge-defined film-fed growth (EFG) method. X-ray fluorescence spectrometer (XRF) confirmed a Ni doping concentration of 0.544 at%. The crystal exhibited a rocking curve with a full width at half maximum (FWHM) of 65.13 arcsec and clear, symmetric Laue patterns. The ultraviolet–visible (UV–Vis) transmission spectrum showed a cutoff edge at 265.5 nm, yielding a bandgap of 4.67 eV. Moreover, the semi-insulating behavior of Ni: β-Ga 2 O 3 was indicated by the infrared absorption edge extended beyond 10 μm. Raman spectroscopy revealed lattice distortion due to Ni 2+ incorporation, causing shifts in peak positions and intensities without phase change. A metal–semiconductor–metal (MSM)-structured X-ray detector based on Ni: β-Ga 2 O 3 was fabricated and characterized under various biases and dose rates. The device exhibited excellent stability at 1000 V with a high sensitivity of 663.36 μC/Gy·cm 2 , outperforming detectors from other semi-insulating β-Ga 2 O 3 crystals due to its superior crystal quality and high breakdown strength. Furthermore, low oxygen vacancy concentration contributed to fast response times of 0.20 s (rise) and 0.23 s (fall). The detection limit was estimated to be 12.04 nGy/s, highlighting its potential for low-dose X-ray detection.

Owing to the natural abundance of sodium, sodium-ion batteries (SIBs) serve as a more cost-effective option compared with lithium-ion batteries (LIBs), while offering comparable energy storage capabilities. This study presents the compositional optimizations, structural characterizations, and electrochemical performance of a new mixed sodium (Na) superionic conductor (NASICON)-type polyanionic material, NaFe 2 PO 4 (SO 4 ) 2 (NFPS). Subsequently, the introduction of Ni 2+ doping serves to simultaneously improve the structural integrity and electronic conductivity of the material, leading to a collective enhancement of the sodium-ion diffusion channels. The Ni 2+ -incorporated phase, NaFe 1.92 Ni 0.08 PO 4 (SO 4 ) 2 , exhibits faster Na + diffusion, resulting in superior rate and cycling performance versus NFPS. After 80 cycles at 25 mA g −1 , NFPS-Ni 0.08 maintains a discharge capacity of 58.7 mA h g −1 , outperforming undoped NFPS by 20%.

Chinese Korean ethnic rice wine (CKRW), a traditional fermented wine made from rice or corn, has antioxidant and antihypertensive activities. There is no report on the study of α-Dicarbonyl compounds (α-DCs) in CKRW currently. The sensitive UHPLC-MS/MS method based on a novel derivatization reagent 3-benzyl-2-oxo-4λ3-thiazolidine-4-carbohydrazide (BOTC). It was used to label three α-DCs, including glyoxal (GO), methylglyoxal (MG) and 3-deoxyglucoside (3-DG) in rice wine. The calibration curves obtained good linearity (R 2 > 0.9997) and a relatively wide range of concentrations from 0.39 to 62.5 µM. LOD were 25–50 fmol. GO, MG, and 3-DG were detected in CKRW for the first time. Then, ten kinds of rice wine were purchased from five suppliers for quantitative comparison. At the result, the contents of the three α-DCs had differences in these wines. 3-DG was higher than the other two α-DCs. The method provided a reference for the detection of α-DCs in other fermented alcoholic drinks. Graphical abstract

Acne vulgaris, a prevalent inflammatory skin disorder, poses significant clinical challenges due to its multifactorial pathogenesis involving Propionibacterium acnes ( P. acnes ) proliferation and chronic inflammation. Conventional therapies, including topical applications, oral medication, and laser treatments, face limitations in drug penetration, patient compliance, and therapy efficacy. Currently, the combined use of hydrophilic drugs and hydrophobic drugs is a commonly recommended clinical approach. However, conventional formulations severely struggle to effectively deliver and release both therapeutic agents at the affected site. To address these issues, we developed the dissolved bubble microneedle patches (DBMNPs) for the co-delivery of hydrophilic (dipotassium glycyrrhizinate, DPG), hydrophobic (PIONIN) drugs, and alongside salicylic acid (SA) at the same time. The DBMNPs, which were fabricated basing on hyaluronic acid (HA), featured hollow bubble structures to encapsulate lipophilic agents, enabling spatially segregated and temporally controlled drug release. The patches exhibited good mechanical strength, excellent biocompatibility, and potent antimicrobial activity against P. acnes . In vivo studies confirmed their efficacy in treating acne vulgaris, offering a minimally invasive and clinically translatable approach to enhance therapeutic effect while minimizing systemic side effects. This study reports a microneedle platform that successfully addresses the key challenge of co-loading and co-delivering both hydrophilic and hydrophobic drugs, and is expected to be applied in the treatment of other skin diseases.

Mixed-ligand metal organic frameworks have received great attentions as novel sorbents for sample preparation due to their fascinating structures and intriguing functionalities. Here, we report the fabrication of mixed-linker ZIF-8-90 s with tunable properties for effervescent tablet-assisted dispersive solid-phase extraction (ET-DSPE) of polycyclic aromatic hydrocarbons (PAHs) in environmental water before HPLC separation and hydroxyl metabolites of PAHs (OH-PAHs) in urine samples prior to LC-MS/MS. ZIF-8-90 s based effervescent tablets possessed the high affinity towards analytes via Zn-O bond and π-π interaction, and afforded a great excluding ability to interfering components from urine samples. ET-DSPE of PAHs from 15 mL water sample with ZIF-8 25 -90 75 gave enhancement factors of 122–155, linear ranges of 4-10 5 ng/L, detection limits ( S/N = 3) of 1–8 ng/L, and recoveries of 81.1%-103%. For the determination of OH-PAHs, the proposed ET-DSPE method using ZIF-8 85 -90 15 allowed direct loading of 4 mL of crude human urine sample and provided the linearity range of 0.004-100 ng/mL, detection limits of 0.001–0.008 ng/mL, and recoveries of 82.1%-104%. In conclusion, ZIF-8-90-based ET-DSPE coupled with HPLC and LC-MS/MS were successfully applied to monitor both PAHs in environmental water and OH-PAHs in urine in a facile, efficient and reliable way.

Cellulose-based ionogels are promising for flexible electronics and energy devices, yet their performance is often constrained by the trade-offs among mechanical robustness, ionic conductivity, and thermal stability. Here, we propose a synergistic strategy that integrates dual-ions complexation with crystallization-induced molecular assembly to fabricate a cellulose ionogel. This strategy results in a comprehensive ionogel (noted as Cry-gel) with high mechanical strength (2.3 MPa in tension and 5.3 MPa in compression) and high ionic conductivity (96.8 mS cm −1 ). Moreover, the Cry-gel can maintain impressive structural stability across a temperature range of −40 to 80 °C. Flexible thermoelectric devices and smart sensors derived from Cry-gels demonstrate a voltage of 0.28 V at a temperature gradient of 60 K, an impressive Seebeck coefficient of 6 mV K −1 , and high sensitivity to pressure, temperature, touch, and human pulse. This work provides a paradigm for creating multifunctional sustainable materials, effectively bridging the gap between high-performance ionogels and their applications in cutting-edge bioelectronics and energy harvesting systems.

Curcuma wenyujin is recognized as one of the traditional Chinese medicinal herbs classified under the ‘Eight Flavors of Zhejiang’. This herb is characterized by its high content of volatile oils and curcumin, with sesquiterpenes being the primary component. It exhibits a range of pharmacological activities, including anti-tumor, anti-inflammatory, and antiviral effects. The quality and yield of C. wenyujin are significantly influenced by abiotic stresses, with salt-alkali stress being one of the key factors among them. In this study, C. wenyujin was exposed to salt-alkali stress, with its leaves serving as the primary research object. Transcriptome and metabolome sequencing analyses were performed to explore the associated pathways and key genes in C. wenyujin that respond to salt-alkali stress. The results of transcriptome sequencing revealed a total of 438 differentially expressed genes significantly enriched in 12 pathways, including Biosynthesis of secondary metabolites, Metabolic pathways and Zeatin biosynthesis. Through comprehensive analysis, we have identified two key candidate genes, CwPER5 and CwBGLU32 , which are highly Likely to be involved in regulating metabolite synthesis under stress conditions. Additionally, non-targeted metabolomics sequencing identified a total of 781 metabolites, among which 166 were found to be significantly differentially accumulated. The most annotated metabolites were linked to the Biosynthesis of plant secondary metabolites pathway, followed by the ABC transporters pathway and the biosynthesis of alkaloids derived from ornithine, lysine and nicotinic acid pathway. This research offers a scientific foundation for the development and utilization of traditional Chinese medicine resources, specifically C. wenyujin , as well as a theoretical basis for breeding new varieties of C. wenyujin that exhibit resistance to salt-alkaline stress.

Amide functional group is useful in all branches of molecule-based science. Hundreds of amide synthetic protocols have been invented over the history of organic chemistry either through developing new coupling reagents or engineering non-traditional coupling partners. However, the click-type amide ligation that operates under biocompatible conditions with high chemoselectivity and rapid kinetics is rare. Herein we report that native amines react with α-halo acylsilanes to afford amides selectively with rapid kinetics. Enabled by a tandem silyl-migration/desilylation process, this amide ligation tolerates a wide range of unprotected polar functional groups and proceeds even at diluted concentrations. Beyond the synthesis of simple amides and peptides in both solution and solid phase, it is also applicable to selective functionalization of complex natural products, protein bioconjugation and synthesis of non-conventional functional polyamides under mild conditions.
