Spodoptera frugiperda (J. E. Smith) is a globally invasive pest that poses significant threats to a variety of crops. It has a wide host range of more than 353 recorded plants from 76 families. However, the herbivorous insects could have adaptation mechanisms through physiological modifications in response to constitutive defenses of different host plants. The results revealed that feeding different host plants could significantly affect LC 50 s of broflanilide, chlorantraniliprole, tetraniliprole, indoxacarb, metaflumizone, lufenuron, methoxyfenozide, and spinetoram to S. frugiperda compared to rearing on Zea mays (L.). Detoxification enzyme activity assays and synergist tests indicated that changes in detoxification enzyme activity cause alterations in the susceptibility of S. frugiperda to insecticides. Knockdown of UGT40F3 using RNA interference (RNAi) significantly increased susceptibility to tetraniliprole in all host-fed strains. Microscale thermophoresis (MST) and molecular docking revealed a robust tetraniliprole-UGT40F3 interaction, suggesting that UGT40F3 plays a pivotal role in tetraniliprole metabolism. These results showed that different host plants can influence the detoxification enzyme activity of S. frugiperda , leading to variations in its susceptibility to insecticides. These findings provide a scientific foundation for developing effective pest management strategies.

The accumulation of antibiotics in the environment and their increasing ecological risks make it essential to develop efficient and cost-effective technologies for treating refractory antibiotics-containing wastewater. Compared with conventional physical adsorption and biodegradation, electrochemical advanced oxidation processes (EAOPs) offer advantages including simple operation, free of additional chemicals, mild reaction conditions, and the ability to achieve both pollutant degradation and resource recovery. The carbon-based membrane shows great potential to be applied as a catalytic electrode, performing functions as conventional supports. This study fabricated self-supporting carbon nanofibrous membranes modified with phenolic resin (PR) by an electrospinning-thermal treatment strategy. The structural, conductivity, and mechanical properties of membranes prepared by four PR loading methods (immersion, spray coating, blend electrospinning, and grinding-remolding) were systematically studied. Owing to its superior conductivity and mechanical strength, the PR-I@PTA/ACFs-10 membrane prepared by the immersion method was selected as the working electrode in a flow-through electrocatalytic system for degrading tetracycline (TC). This configuration forces the reaction solution through the anode and cathode, significantly enhancing convective mass transfer and reactant contact. The results indicate that under conditions of 2.5 V, pH = 6, and 10 mM Na 2 SO 4 , the degradation rate of 10 mg L -1 TC reached 85.07% within 1 h. Through characterization techniques and DFT calculations revealed the synergistic mechanism of PR modification in promoting the generation of ·OH and optimizing electron transport pathways. The primary intermediates and potential degradation pathways were identified by LC-MS and DFT LUMO-HOMO calculations, providing deep insights into the complex transformation processes during TC degradation.

ARMS (ankyrin repeat-rich membrane spanning) is a scaffold protein essential for neurotrophic signaling, synaptic development, and cytoskeletal remodeling. Despite its central role in neuronal function, how ARMS is regulated at the molecular level remains poorly understood. Here, we identify GABARAP, an Atg8-family autophagy adaptor, as a novel ARMS-binding protein that directly interacts with its N-terminal ankyrin repeats. We present the crystal structure of the ARMS-GABARAP complex, revealing an atypical interaction mode distinct from canonical LIR-dependent Atg8 interactions. Remarkably, ARMS specifically binds to the GABARAP subfamily of Atg8 proteins, setting it apart from the LC3 subfamily. Functional analysis demonstrates that GABARAP negatively regulates ARMS-mediated dendritic spine development and maturation in hippocampal neurons. Additionally, disrupting the ARMS-GABARAP complex using ankyrin-derived peptides alters ARMS subcellular localization, increasing its accumulation in the soma of neurons. Collectively, our findings uncover a novel ARMS-GABARAP interaction mechanism, establish the regulatory role of this complex in neuronal protein homeostasis, and suggest potential therapeutic strategies for targeting scaffold protein interactions in neurodevelopmental and neurodegenerative disorders.

The development of fully biobased epoxy resins as sustainable alternatives to petroleum-based counterparts is of great significance for addressing resource depletion and environmental concerns. A fully biobased epoxy thermoset was synthesized from a magnolol-derived epoxy monomer (MG-EP) and a furfurylamine-based diamine curing agent (BDFA). The chemical structures were confirmed by FT-IR and ¹H NMR. The MG-EP system showed lower viscosity (0.475 Pa·s) than commercial DGEBA, indicating better processability. The cured biobased epoxy resin exhibited a storage modulus of 1.22 MPa at 30 °C, which was close to that of its petroleum-based counterpart. In addition, the cured biobased epoxy resin showed a tensile strength of 73.8 MPa–35.7% higher than that of DGEBA/BDFA. Moreover, it demonstrated enhanced char yield (44.9% vs. 21.6%) at 800 °C, and reduced heat release (PHRR 173.1 W/g vs. 216.6 W/g, THR 20.3 kJ/g vs. 26.1 kJ/g) compared to those of DGEBA/BDFA. As a result, MG-EP/BDFA achieved a V-1 UL-94 rating. This work presents a promising strategy for developing high-performance fully biobased epoxy resins with integrated mechanical strength and fire safety.

A highly sensitive fluorescent lateral flow immunoassay (LFIA) was developed for SARS‑CoV‑2 IgG detection. Polystyrene (PS) microspheres were synthesized via emulsion polymerization, doped with dipyridamole (Dip), and coated with a protective silica (SiO 2 ) shell through a sol–gel process. After amine functionalization, the SARS‑CoV‑2 nucleocapsid (N) protein was covalently immobilized onto the microsphere surface using EDC/NHS chemistry, yielding PS@Dip@SiO 2 –N fluorescent probes. The LFIA strip enabled one‑step detection within 15 min. Under optimized conditions (N protein conjugation concentration of 40 µg/mL), the strip showed excellent specificity with no cross‑reactivity against other human coronaviruses (NL63, OC43, 229E). Quantitative determination based on the T/C grayscale ratio fitted the Hill equation (R² = 0.9782). The detection limit for SARS‑CoV‑2 IgG was 10 ng/mL, approximately two orders of magnitude lower than that of a commercial colloidal gold‑based LFIA strip. This platform provides a rapid, sensitive, and low‑cost solution for point‑of‑care serological screening of COVID‑19. Graphical abstract

Modified TS-1 catalysts were prepared by treating TS-1 with different alkalis for the nitration of aldoxime, and the effect of alkali treatment on catalytic performance was investigated. TS-1 was modified using organic amines such as ethylamine (EA), triethylamine (TEA), and tetrapropylammonium hydroxide (TPAOH), as well as inorganic bases such as NaOH, KOH. The catalysts were characterized by XRD, FT-IR, UV-vis, N 2 adsorption etc., which showed that the volume of mesopores increased and the skeleton structure remained basically unchanged by the ethylamine-modified TS-1 and the TPAOH-modified TS-1. The highest yield of 1-nitropropane increased 78% when propionaldehyde oxime was catalyzed by the 0.1 mol/L ethylamine treated sample TS-1-EA-0.1. The enhanced catalytic performance of TS-1 after ethylamine treatment may be attributed to the matching between the pore size of modified TS‑1 and the molecular size of propionaldehyde oxime. Subsequently, TS-1-EA-0.1 was used to catalyze acetaldoxime and butyraldehyde oxime. The results revealed that this catalyst was suitable for acetaldehyde oxime as expected, but less effective for the oxidation of butyraldehyde oxime with a larger molecular diameter than propionaldehyde oxime to 1-nitrobutane.

The binder-jet forming technique, combined with a simplified phenolic resin impregnation process, was used to prepare high-performance silicon carbide ceramics. The carbon enhancement process was explored using a pre-mixed phenolic resin and cyclic impregnation, while cyclic pyrolysis was replaced by a baking process at 120ºC. The effects of different printing powders and impregnation cycles on the molding accuracy, density, residual silicon content, thermal conductivity, and mechanical properties of the samples were systematically investigated. The results showed that the printed density was 1.53 g/cm 3 , with a carbon density of 0.55 g/cm 3 . The phenolic resin impregnation treatment effectively filled the internal pores, further increasing the green body density to 1.71 g/cm 3 and the carbon density to 0.71 g/cm 3 . The density of the SiC ceramics obtained by the silicone infiltration process reached 2.93 g/cm 3 , the thermal conductivity was 151.8 W/(m · K), and the flexural strength was 241 ± 14.08 MPa. Overall, cyclic post-impregnation of phenolic resin without the pyrolysis process can effectively enhance the density and properties of binder-injected SiC ceramics.

To characterize sensory differences among commercially available Chenxiang Tieguanyin with different labeled vintages and establish an objective discrimination method, Tieguanyin samples labeled from 5 to 40 years were analyzed using chemometrics and molecular sensory approaches. Amino acids and ester-type catechins decreased significantly with increasing labeled vintage, whereas theabrownin content increased steadily. Volatile profiles remained relatively stable between 10 and 25 years, while aroma characteristics gradually shifted from floral/fruity to aged, woody, and medicinal attributes, accompanied by enhanced mellowness and smoothness. A total of 22 key differential volatiles associated with labeled vintage were identified. Molecular docking and aroma recombination experiments were combined to systematically validate their contribution to the typical aged aroma of Tieguanyin. Among the machine-learning models, the convolutional neural network (CNN) exhibited the best classification performance, achieving 92.86% accuracy. This study provides an effective strategy for quality evaluation and labeled vintage discrimination of Chenxiang Tieguanyin.

Revealing the mechanism of photocatalytic organic transformation in aqueous solutions is crucial for photocatalytic processes, yet precisely regulating complex interfacial electron transfer and the microenvironment of reaction molecules remains challenging. Inspired by cellular structures and natural metalloproteins, we construct a ZIF-67@CoS/CdS nanoreactor mimicking organelle architecture. This system enables directional charge transport and hydrogen-bond microenvironment regulation, allowing efficient co-production of H 2 and pyruvic acid under light irradiation. Characterizations and calculations reveal that the interfacial electric field accelerates charge migration, while the catalyst reduces the energy barriers for water dissociation and hydrogen formation by modulating hydrogen bonds. The optimized catalyst delivers a molar-level H 2 activity of 1457.1 mmol m −2 (5 h, 1,000 cm 2 ) under sunlight, with a pyruvic acid selectivity of 91.2%. In this work, we propose a design strategy for an organelle-mimetic nanoreactor for scalable sunlight-driven H 2 production and selective pyruvic acid synthesis.

Elevated CO 2 (eCO 2 ) and arbuscular mycorrhizal fungi (AMF) positively influence plant defense under heavy metal exposure individually, however, the combination of them and the contribution of eCO 2 were still unclear. The pot experiment was employed to explore the combined effect of eCO 2 (700 ppm) and Funneliformis mosseae on the defense of black locust ( Robinia pseudoacacia L.) grown in cadmium (Cd)-polluted soils by 13 C isotope tracer. Elevated CO 2 significantly caused an increase in Cd content, decreases in contents of malonaldehyde, carotenoids, soluble sugars and proteins, metallothioneins (MTs) and proline and activities of superoxide dismutase, catalase, peroxidase, ascorbate peroxidase and glutathione peroxidase and increases in ascorbic acid (AsA), glutathione (GSH), cysteine (Cys) and phytochelatins (PCs) in leaves under F. mosseae colonization. Additionally, the indirect contributions of eCO 2 to AsA, GSH, Car, proline, soluble sugars and proteins, Cys, PCs and MTs under eCO 2 + F. mosseae were lower than that under eCO 2 alone. Overall, eCO 2 enhanced the defense of black locust colonized by F. mosseae under Cd exposure by stimulating AsA, GSH, PCs and Cys synthesis, which will provide some insights into the effect of global change on the resistance mechanism of plants colonized by AMF to heavy metals.

To enhance the electrochemical performance of high-nickel and cobalt-free cathode material LiNi 0.9 Mn 0.1 O 2 (NM), this study proposes a synergistic strategy integrating high-shear pH-regulated precipitation to fabricate uniform micron-sized structured precursors, with Se-surface modification to enhance the cycling stability. First, the optimal sample NM-8.1 was synthesized via high-shear precipitation with the controlling pH value of 8.1, exhibiting the initial discharge capacity of 208.3 mAh g −1 at 25 °C and 0.1 C (2.7–4.4 V) and the capacity retention of 79.9% after 200 cycles at 1 C. Then, Se-driven surface coating was prepared to improve the cycle stability for NM-8.1, and the optimized NM-1Se shows the initial discharge capacity of 210.7 mAh g −1 (25 °C, 0.1 C, 2.7–4.4 V), the capacity retention of 88.5% after 200 cycles (1 C) and 82.3% after 500 cycles at 5 C. After 200 cycles (1 C), the R ct value equals 60.42 Ω for NM-8.1, whereas 29.08 Ω for NM-1Se. X-ray diffraction (XRD), high-resolution transmission electron microscopy (HRTEM), scanning electron microscopy (SEM), cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS) analyses indicate that both the uniform, micron-sized structured precursors and the Se modification can promote Li + diffusion, stabilize the lattice oxygen and decelerate the growth of charge transfer impedance, thereby enhancing the cycling stability of the cathode material. This work offers a generalizable paradigm for the synthesis of advanced electrode materials, providing valuable guidelines for optimizing the preparation of other high-energy-density batteries. Graphical abstract Synergistic pH-regulated precipitation and Se surface modification enhance the capacity, cycling stability, and reaction kinetics of cobalt-free Ni-rich cathodes for high performance lithium-ion batteries.

A lateral flow analysis (LFA) strip for detecting dual miRNAs (miR155 and miR21) was constructed based on the “AND” logic gate and DNA self-assembly. The ternary synergistic strategy of “logic gating-signal amplification-visual output” enables highly sensitive and visual detection of miR21 and miR155 for breast cancer diagnosis. Only if both miR21 and miR155 are present can the trigger DNA (TDNA) in the sensor specifically dissociate and activate the “AND” logic gate (output signal = “1”); in the absence of either miRNA, the system remains in an inactive state (output signal = “0”). TDNA initiates catalytic hairpin assembly (CHA), and the product of the CHA reaction cascaded triggers the hybridization chain reaction (HCR) to achieve dual signal amplification. Gold nanoparticles (AuNPs) were used to label DNA for the construction of the LFA strip, allowing naked-eye observation of the detection results of miR21 and miR155. Detection results showed that the signal intensity of the test line (T line) had a positive correlation with the concentration of miRNAs (with a miR155:miR21 ratio of 1:1). Within the concentration range of 0.1–10 nM, the average grayscale value of the T line exhibited a good correlation with the logarithm of miRNA concentration (correlation coefficient r = 0.9983), and the limit of detection (LOD) was 30.98 pM. This LFA strip has been preliminarily validated to the detection of human serum samples, and the results indicated that the levels of miR155 and miR21 in the serum of breast cancer patients were significantly higher than those in normal individuals. Free from the limitation of large-scale instruments, this strip holds great commercialization potential. Graphical abstract
