In this study, Se-Sb alloy coatings were successfully fabricated for the first time via constant potential electrodeposition from a choline chloride–ethylene glycol deep eutectic solvent. The correlation between deposition potential and the morphology, composition, crystal phase, optical, and electrical properties of the coatings was systematically investigated. The results showed that as the deposition potential shifted in the negative direction, the fibrous morphology of the coatings initially became denser and subsequently looser. Correspondingly, the Se content first decreased and then increased, while the Sb content exhibited the opposite trend. The crystalline structure was primarily characterized by an amorphous Sb 2 Se 3 phase. Although both the bandgap and photocurrent response initially increased and then decreased with more negative deposition potentials, the coatings consistently exhibited excellent p-type semiconductor characteristics. Chronoamperometry (CA) analysis indicated that the nucleation mechanism of Se-Sb alloys transitioned from diffusion-controlled three-dimensional (3D) progressive nucleation to diffusion-controlled 3D instantaneous nucleation as the deposition potential shifted from −0.45 V to −0.65 V. Furthermore, cyclic voltammetry (CV) analysis revealed an induced co-deposition mechanism: Se was first deposited on the FTO substrate, which subsequently induced the co-deposition of Se and Sb to form the Se-Sb alloy coatings. Finally, a comparison with coatings annealed at 300 °C demonstrated that annealing significantly improved the crystallinity, resulting in the formation of crystalline Sb 2 Se 3 . However, the photocurrent response decreased by a factor of 5.18. These findings suggest that the as-deposited Se-Sb alloy coatings exhibit superior photoelectrical performance compared to their annealed counterparts, highlighting their promising potential for photoelectric applications.

The interfacial arrangement of surfactant molecules dictates the properties of adsorption films, rendering the molecular adsorption mechanisms fundamentally critical. This study integrates interfacial dilational rheology with molecular dynamics simulation to unravel the adsorption mechanism of renewable sorbitol-alkylamine surfactant (SAAS-C12) at air/water (A/W) and n-decane/water (D/W) interfaces. We report the first discovery that hydrogen-bond switching governs the precise modulation of interfacial film strength: at the A/W interface, the transition from intramolecular hydrogen-bonded rings (low-concentration, irreversible adsorption) to intermolecular hydrogen-bonded networks (high-concentration, reversible adsorption) drives a distinctive bimodal dilational modulus trend while confining relaxation processes to slow molecular rearrangement. At the D/W interface, n-decane molecules weaken the interaction between surfactant alkyl chains by competing with surfactant molecules via van der Waals forces, converting the high-concentration modulus maximum to a gradual-decay plateau and concurrently redirecting dominant relaxation toward rapid diffusion exchange. Clarifying the mechanism of the interfacial dilational modulus dominated by hydrogen bonds helps to design green surfactants with good foam performance, showing promise for sustainable applications in the food industry, pharmaceutical delivery, and enhanced oil recovery.

All-solid-state lithium batteries (ASSLBs) are in the spotlight due to their superior safety and enhanced energy density. However, the inferior interface compatibility of electrolyte/electrodes and room temperature ionic conductivity hinder their practical application. Here, we innovatively utilize POSS-crosslinked high-permittivity vinylene carbonate and ionic liquids in multiscale nanocellulose membranes to in-situ solidify polymer electrolytes, achieving ASSLBs with excellent interface compatibility and ionic conductivity. Specifically, multiscale nanocellulose membranes prepared from cellulose nanocrystals and cellulose nanofibers serve as support separators, which can effectively absorb polymer precursors and facilitate lithium-ion transport through abundant hydroxyl groups and nanostructures, realizing high ionic conductivity of 1.10 × 10 −4 S cm −1 at 30 °C. Moreover, the octa-functionalized POSS further enhances the solid-solid interface by forming a highly crosslinked polymer network through in-situ polymerization with active monomers, thereby strengthening the stability of ASSLBs. The above in-situ solidification strategy ultimately achieves robust electrode/electrolyte interfaces and optimizes the long cycle capability of ASSLBs. Li||Li cells can run stably for more than 1200 h at a current density of 0.2 mA cm −2 without noticeable polarization. Furthermore, Li||LFP cells maintain excellent stability after 800 cycles at 1C with a superior capacity retention of 70 % at 55 °C and exhibit excellent rate performance. This work provides an effective strategy to fabricate high-performance ASSLBs and a new solution for the high-value utilization of naturally renewable cellulose resources.

Light quality is a critical regulator of plant morphology and physiological metabolism, with spectral optimization emerging as a key strategy for enhancing bioactive compound production in medicinal plants. Catharanthus roseus , valued for its alkaloid content, exhibits significant metabolic plasticity in response to light conditions. This study examined the effects of two red-to-blue light ratios [2:1 (R2B1) and 7:1 (R7B1)] on morphophysiological responses, metabolite profiles, and alkaloid accumulation in C. roseus , using white light as a control. Both R2B1 and R7B1 altered plant morphology and enhanced alkaloid synthesis. R2B1 notably increased antioxidant enzyme activity, while R7B1 boosted non-enzymatic antioxidants and phenolic compounds. The Integrative Biomarker Response version 2 analysis identified R7B1 as the optimal treatment for promoting the accumulation of bioactive compounds. Untargeted metabolomics revealed that R7B1 enhanced sugar levels and induced tissue-specific changes in organic acid metabolism. Correlation analysis suggested that red-to-blue light promotes alkaloid biosynthesis by modulating antioxidant systems and key metabolic pathways. These findings highlight the potential of red-to-blue light optimization to enhance alkaloid production in C. roseus , providing valuable insights into the regulation of secondary metabolism and practical strategies for improving bioactive compound yields in medicinal plants.

Legumes are important sources of dietary lipids, and lipidomic analysis of legumes using UPLC-QTOF-MS is crucial for human health. This study characterized and compared the lipid profiles of black soybean, mung beans, chickpeas, peas, fava beans, cowpeas, adzuki beans, and kidney beans, and investigated the effects of soaking and cooking. Sixteen subclasses comprising 520 lipids were identified, with 170 differential lipids among the eight legume types. Soaking for 12 h decreased the fatty acids (FAs) and lysophospholipids (LPLs), and increased the triacylglycerols, ceramides, phosphatidylethanolamines, diacylglycerols (DGs), monogalactosyldiacylglycerols (MGDGs), phosphatidic acids (PAs), phosphatidylinositols (PIs), and phosphatidylserines (PSs). Cooking for 20–55 min reduced the LPLs, FAs, phosphatidylglycerols, and sphingomyelin 42:8;O2, but increased the MGDG 36:4, MGDG 36:3, MGDG 36:2, digalactosyldiacylglycerol (DGDG) 36:4, DGDG 36:5, PA, PI, and PS levels. These findings offer valuable insights for legume selection and authenticity assessment and elucidate the effects of soaking and cooking on legume seed lipids.

Reduced nicotinamide adenine dinucleotide (NADH) salvage pathway reconstitution is a crucial step toward autonomous artificial cells. In living systems, D-ribose is a fundamental precursor intricately involved in the synthesis of nucleotides, nucleic acids, and critical metabolic pathways. An NADH synthesis pathway in artificial cells starting from D-ribose was constructed with five-enzyme cascade containing ribokinase, ribose-phosphate pyrophosphokinase, nicotinamide phosphoribosyltransferase, nicotinamide mononucleotide adenylyltransferase, and formate dehydrogenase (RK, RPPK, NAMPT, NMNAT, and FDH), which efficiently converted 10 mM D-ribose into 415 μM NADH within 80 minutes under optimized conditions. The produced NADH was further used to drive the amino acid metabolism, i.e., to convert NH4+ and α-ketoglutarate to glutamate by introducing additional glutamate dehydrogenase (GDH) inside artificial cells. The successful reconstitution of NADH synthesis pathway lays the foundation for fabricate artificial cells with complicated metabolic net works.

Brassica napus (oilseed rape) is sensitive to boron (B) deficiency and exhibits young leaf curling in response to low-B stress at the seedling stage, which leads to reduced photosynthesis and plant growth. So far, no gene has been identified to be involved in B deficiency induced leaf curling. Our previous results showed the transcription factor BnaA1.WRKY53 might be involved in B-deficiency tolerance. However, altered BnaA1.WRKY53 expression does not influence B concentration in shoot, root and leaf cell walls, which suggests BnaA1.WRKY53 might be involved in other biological processes. Indeed, phenotypic and anatomical analyses revealed that BnaA1.WRKY53 negatively regulated the leaf curling induced by leaf epinasty by suppressing the overexpansion of palisade cells under B deficiency. Further transcriptome enrichment analysis of differentially expressed genes (DEGs) between wild-type and BnaA1.WRKY53 overexpression line showed auxin response pathway was enriched. In addition, Arabidopsis DR5::GFP auxin reporter line showed B deficiency caused predominant auxin signal accumulation in the adaxial side and concomitant adaxial cell expansion, which indicated that B deficiency may induce leaf curling by altering auxin distribution. Phytohormone quantification and gene expression analysis demonstrated that BnaA1.WRKY53 prevent auxin overaccumulation in leaves by suppressing auxin biosynthetic genes under B deficiency. Furthermore, exogenous 1-naphthlcetic acid (NAA) treatment experiments revealed that high auxin could induce leaf curling and BnaA1.WRKY53 expression. Overall, these findings demonstrate that auxin and the transcription factor BnaA1.WRKY53 synergistically regulate leaf curling to maintain an optimal leaf area under B deficiency, and providing novel insights into the resistance mechanisms against B-deficiency-induced leaf curling in oilseed rape.

To investigate the role of IL-17 in macrophage M1 polarization within a type 2 diabetic (T2DM) milieu and to evaluate the therapeutic potential of its neutralizing antibody. PMA-differentiated THP-1 macrophages were polarized to M1 state. Under high glucose, cells were treated with IL-17 and an IL-17 neutralizing antibody. Inflammatory cytokines (IL-1β, IL-6, TNF-α) were measured; mRNA levels of TNF-α, HIF-1α, and NLRP3 were assessed by qPCR; and protein expression related to the NF-κB, mTOR/HIF-1α axis and pyroptosis (NLRP3, Caspase-1, GSDMD) was analyzed by Western Blot. High glucose and IL-17 synergistically promoted M1 polarization, enhancing proinflammatory cytokine secretion. This was associated with activation of the NF-κB, mTOR/HIF-1α signaling axis and induction of pyroptosis, evidenced by NLRP3 inflammasome assembly, Caspase-1 activation, and GSDMD cleavage. The IL-17 neutralizing antibody effectively suppressed these pathological processes. IL-17 acts as a key immunological amplifier in diabetes, driving M1 polarization, oxidative stress, and pyroptosis via the NF-κB, mTOR/HIF-1α axis and NLRP3 inflammasome. Treatment with an αIL-17 effectively reversed the aberrant activation of the aforementioned cellular phenotypes and signaling pathways, partially restoring macrophage functional balance. This finding provides preliminary experimental support for further exploration of IL-17-targeted immunomodulatory strategies to ameliorate diabetes-associated metabolic inflammation.

Fatty Liver Hemorrhagic Syndrome ( FLHS ) is a metabolic disorder characterized by hepatic lipid metabolism dysfunction in poultry. This study aimed to investigate the efficacy and underlying mechanism of a solid dispersion of genistein ( SDG ) in ameliorating FLHS in laying hens. In this study, a total of 60 Lohmann gray laying hens, aged 40-week-old, were randomly divided into five groups including the control group (normal diet), MOD group (high-energy low-protein diet; HELP diet), GEN group (400 mg/kg GEN + HELP diet), SDG group (3200 mg/kg SDG + HELP diet), and physical mixture of GEN group (PMG) (3200 mg/kg PMG + HELP diet). The results demonstrated that all three treatment groups exerted therapeutic effects on FLHS, with SDG exhibiting the superior efficacy. SDG improved the production performance of laying hens, modulated hepatic function, and reduced blood lipid levels. Furthermore, SDG supplementation attenuated intestinal pathological damage and restored intestinal permeability and barrier function. Meanwhile, SDG reshaped gut microbiota structure and metabolite composition, increasing the abundance of Akkermansia, UCG-008, Elusimicrobium, Zag_111 , and phosphoglycerides ( P < 0.05), and reducing Bifidobacterium and lysophospholipids ( P < 0.05). Transcriptomic analysis showed that the pyruvate metabolism pathway was significantly enriched. SDG upregulated the expression of PCK2, PC , and ACAT2 within this pathway, while downregulating the expression of ME1 . The underlying mechanism may involve the inhibition of hepatic triglyceride synthesis, the facilitation of free cholesterol conversion into cholesterol esters, and the promotion of oxaloacetate and acetyl-CoA entry into the tricarboxylic acid cycle, thereby suppressing hepatic lipid deposition. In conclusion, our study demonstrated solid dispersion technology enhanced the effect of GEN on alleviating FLHS, and established a foundation for applying SDG to improving poultry liver health.

Background The diffusion gradient in thin-films (DGT) device is widely used for in situ measurement of pollutants in aquatic environments, offering high enrichment efficiency and robustness to environmental variations such as temperature and hydrodynamics. These characteristics make DGT particularly suitable for monitoring a diverse array of trace organic contaminants in waters. However, long-term deployment is often compromised by biofilm formation on the sampling outer membrane, which can obstruct analyte diffusion and lead to underestimation of analyte concentrations. This study addresses the need for a biofouling-resistant DGT device that maintains accuracy during extended field applications. Results A novel DGT device incorporating an antifouling Ag/polydopamine-modified polyethersulfone (Ag/PDA-PES) membrane was developed. The modified membrane demonstrated dual functional improvements: a 40 % reduction in water contact angle, indicating enhanced hydrophilicity, and strong antimicrobial efficacy, evidenced by an inhibition zone of 1165 μm ± 110 μm against Escherichia coli , while maintaining diffusion characteristics comparable to the original PES membrane. In extended deployment in both simulated and natural waters, the Ag/PDA-PES membrane effectively inhibited biofilm formation and maintained stable analyte diffusion coefficients over time compared to the unmodified membrane. The DGT devices showed constant sampling performance across varying pH (5.0–9.0), ionic strength (0–200 mM NaCl), and dissolved organic matter levels (0–20 mg/L). Field validation confirmed the device reliability, with measured total antibiotic concentrations (692–1062 ng/L) consistent with grab sampling. Significance This work signifies a step forward in DGT passive sampling technology by integrating antifouling properties directly into the membrane, thereby enabling accurate long-term monitoring of pollutants in biofilm-prone waters. Moreover, this study provides a promising strategy for improving the reliability of long-term DGT sampling, with meaningful implications for the precise monitoring and ecological risk assessment of other emerging pollutants.

The development of high-performance electromagnetic wave absorbing materials has become crucial for addressing electromagnetic pollution. This study reports a facile in situ ion exchange strategy followed by pyrolysis for the successful preparation of N-doped porous carbon foam embedded with uniformly dispersed magnetic Fe3C/Fe nanoparticles (Fe3C/Fe@NPCF). The strong coordination between carboxyl groups on the polyamic acid (PAA) chains and Fe3+ ions effectively prevents the agglomeration of magnetic particles during high-temperature treatment and achieves their high dispersion within the carbon matrix. The effects of carbonization temperature on the microstructure, electromagnetic parameters, and microwave absorption properties were systematically investigated. The results demonstrate that the Fe3C/Fe@NPCF-800 composite exhibits exceptional microwave absorption performance with a minimum reflection loss (RLmin) of −30.19 dB at a minimal thickness of only 2.0 mm and an ultra-wide effective absorption bandwidth (EAB) of 6.48 GHz. This outstanding performance originates from the introduction of magnetic components that optimize impedance matching, allowing electromagnetic waves to be effectively attenuated. This work not only provides a high-performance absorbing material but also offers a novel design strategy and fabrication method for developing lightweight absorbers with both strong absorption capability and broad bandwidth.

Hypertension prevalence is increasing in both aging and younger populations, with high salt intake being a key environmental driver. Whether young and aged individuals exhibit similar physiological and molecular responses to salt loading remains unclear. This study compared hemodynamic and renal redox adaptations to salt loading in young (8-week) and aged (50-week) Dahl salt-sensitive (DSS) rats. Both groups developed salt-sensitive hypertension, but blood pressure (BP) elevation was markedly lower in aged rats. High salt induced marked increases in stroke volume (SV), cardiac output (CO), and vascular indices, indicating strong cardiac and vascular contributions to BP rise. In contrast, aged rats displayed blunted increases in SV and CO, together with attenuated changes in vascular indices, reflecting diminished cardiac contractility and vascular responsiveness that accounted for their lower BP salt sensitivity. High salt disrupted redox homeostasis in both groups, but aged rats exhibited inherently reduced antioxidant capacity and greater renal oxidative stress, along with more pronounced glomerulosclerosis and interstitial fibrosis. Nitric oxide pathway suppression was more evident in young rats, whereas aged rats showed persistently low baseline NO availability. These findings demonstrate that aging reduces hemodynamic and vascular responsiveness to salt loading yet heightens susceptibility to salt-induced renal injury in DSS rats.
