Synthesis of highly uniform rutile TiO 2 nanorod arrays has long been a priority for fabricating the high-performance memristors, given its great potential as active-layer materials in memristive devices. Herein, a controllable hydrothermal synthesis of highly uniform rutile TiO 2 nanorod arrays on fluorine-doped tin oxide (FTO) substrates is presented. Through systematic investigations, it is revealed that the highly uniform rutile TiO 2 nanorod arrays are obtained via a 3-hour hydrothermal synthesis at 160 °C on vertical FTO substrates, postannealing at 450 °C for 1 hour, followed by 25-minute ultraviolet (UV) irradiation. The obtained TiO 2 nanorod arrays exhibit excellent substrate adhesion and pinhole-free morphology, with well-defined nanorod dimensions (an average diameter of 171 nm and a length of 2.44 μm) and high crystallinity (an average crystallite size of 16.66 nm). Using such nanorod arrays as the active layers, the Ag/TiO 2 /FTO memristive devices demonstrate remarkable resistive switching characteristics: (i) the ratio of high resistance state (HRS) and low resistance state (LRS) reaches 17.7, and (ii) the retention time is predicted to be more than 10 years. Current-voltage analysis indicates that the resistive switching behavior follows a synergistic combination of ohmic conduction and space-charge-limited current (SCLC) mechanisms. The current work offers valuable guidelines for structure-property optimization in highly uniform rutile TiO 2 nanorod array films, demonstrating their promising applications in high-performance memristive devices.

In this study, N'-(4-fluorophenyl)-2-pyridinecarbohydrazide (2-FPH), N'-(4-fluorophenyl)-3-pyridinecarbohydrazide (3-FPH), and N'-(4-fluorophenyl)-4-pyridinecarbohydrazide (4-FPH), which showed considerable antifungal activities against the prochloraz-resistant Penicillium italicum strain (PiR2), were designed and synthesized. Among these, 2-FPH displayed the strongest antifungal activity against PiR2 growth, with minimum inhibitory concentrations (MIC) of 12.5 μg/mL and minimum fungicidal concentrations (MFC) of 25 μg/mL. In vivo antifungal and hemolytic toxicity tests showed that 2-FPH effectively prevented PiR2 infection of citrus fruits, but exhibited exceptionally low hemolytic toxicity. At equivalent concentrations, its biological safety and control efficacy were far superior to those of prochloraz. According to morphological findings, 2-FPH increased cell membrane permeability, caused cell swelling and morphological abnormalities, disrupted structural integrity, and decreased chitin content in cell walls. Physiological, biochemical, and molecular biology investigations indicated that 2-FPH binds to succinate dehydrogenase (SDH), inhibits its enzymatic activity, and suppresses associated gene expression. This decreases intracellular ATP levels, disrupts normal mitochondrial function, and triggers a substantial increase in reactive oxygen species (ROS). In summary, 2-FPH shows promising potential as a possible fungicide and succinate dehydrogenase inhibitor for managing citrus blue mold.

The 3,4-dihydropyrimidin-2(1H)-one (DHPM) scaffold possesses diverse biological activities and chemical tunability, allowing structural modifications to modulate antiviral, anticancer, and anti-inflammatory effects. In this study, a series of DHPM derivatives with varied substituents were designed and synthesized, and their structures were characterized by1H NMR,13C NMR and HRMS. Their antiviral activities against pseudorabies virus (PRV) and vesicular stomatitis virus (VSV) were evaluated. In vitro assays revealed that several compounds exhibited significant antiviral effects, with4bf(SI = 243.08 against PRV),4ce(SI = 196.4 against VSV), and4be(SI = 124.2 against PRV; SI = 181.1 against VSV) showing the most potent activity. Further studies demonstrated effective inhibition of viral titers, and Western blot and qRT-PCR analyses confirmed downregulation of viral proteins and related genes. Cytotoxicity tests indicated that4bf,4ce, and4behad CC50values of 270.0, 147.1, and 190.9 μg/mL, respectively, suggesting favorable safety profiles. In vivo experiments showed that4bf, without affecting normal growth, alleviated PRV-induced pulmonary inflammation and tissue damage, and improved survival in mice. Taken together, DHPM-based compounds demonstrate promising potential as candidate antiviral agents, warranting further development.

A general and mild strategy for the regioselective synthesis of N-alkenyl 2-pyridones via N–C(β) bond formation is reported. Using readily available β-iodovinylsulfones as alkenylating agents, the reaction affords a diverse array of products in moderate to high yields with moderate to excellent Z -selectivity. Various 2-pyridones and β-iodovinylsulfones bearing different functional groups are well tolerated. Notably, this protocol provides an alternative to conventional N–C(α) bond-forming approaches. Gram-scale experiments demonstrate the practical applicability and scalability of this transformation.

ZnIn 2 S 4 is a highly promising photocatalyst, but its rapid carrier recombination remains the core bottleneck. Constructing band-matched heterojunctions to promote charge separation is currently the most effective strategy to address this issue. Herein, a Co 3 (PO 4 ) 2 /ZnIn 2 S 4 (CPO/ZIS) type-II heterojunction photocatalytic system is designed. The intimate coupling between CPO and ZIS is achieved via electrostatic self-assembly. Studies show that this system follows a type-II charge transfer mechanism, and owing to the strong affinity of phosphate groups for protons in aqueous solution and the electron-trapping function of cobalt active centers, the hydrogen production efficiency is synergistically enhanced. The optimal 10-CPO/ZIS composite achieves a HER of 8.87 mmol g −1 h −1 , which is 8.53 times that of pristine ZIS, and also exhibits excellent photocorrosion resistance.

Alkaline hydrogen evolution reaction (HER) is constrained by the Sabatier principle, making it challenging to simultaneously optimize water dissociation and hydrogen desorption. Here, we report a spatially decoupled tandem catalyst, Co(OH) 2 @Mo 2 C, that circumvents this constraint via a hydroxyl-mediated hydrogen spillover pathway. Mo 2 C serves as the *H generation site via rapid water dissociation, while adjacent Co(OH) 2 functions as the *H acceptor and recombination center, with abundant surface hydroxyl groups on Co(OH) 2 accelerating hydrogen spillover from Mo 2 C to Co(OH) 2 and sustaining water dissociation kinetics. CH 3 I poisoning experiments, corroborated by in situ Raman spectroscopy and density functional theory calculations, reveal the critical mediating role of hydroxyl groups in hydrogen migration. The optimized catalyst achieves only 43 mV overpotential to reach 10 mA cm −2 in 1 M KOH, and durability over 150 h at 0.5 A cm −2 in an anion exchange membrane water electrolyzer. This work establishes a generalizable interfacial engineering strategy to circumvent the Sabatier limitation by accelerating hydrogen migration on spatially segregating elementary steps. A spatially decoupled Co(OH) 2 @Mo 2 C tandem electrocatalyst shows that Mo 2 C rapidly dissociates water while Co(OH) 2 efficiently shuttles *H to accelerate H 2 release, where Co(OH) 2 abundant surface hydroxyl groups accelerate hydrogen spillover from Mo 2 C to Co(OH) 2 and maintain water dissociation kinetics.

Gd 2-x Zr 2+x O 7+x/2 ceramics were used to determine how nonstoichiometry in ceramic phases governs CMAS corrosion. All compositions retained a fluorite average structure, but Raman spectroscopy, sintering behaviour and grain growth revealed composition-dependent non-stoichiometry-driven disorder before CMAS contact. During heating, characteristic CMAS spreading temperatures depended only slightly on nonstoichiometric composition, whereas spreading rate and final spreading extent vary markedly with nonstoichiometry. After exposure at 1300 °C, all samples developed a dense inner layer and a fully reacted layer, following approximately linear and square-root time dependences of layer thicknesses, respectively. All nonstoichiometric ceramic compositions outperformed the stoichiometric composition, but the mechanistic origins of these effects were distinctly different depending on the type of nonstoichiometry, defined by different reaction products and layer-specific chemical partitioning. CMAS resistance is therefore strongly influenced by how nonstoichiometry directs competition between corrosion layers.

Traditional Chinese medicine polysaccharides (TCMPs) have attracted growing attention due to their multi-target and multi-level therapeutic effects in the treatment of diabetes. In this study, we systematically evaluated the antidiabetic effect of three TCMPs, including Moringa oleifera Lam. polysaccharide (MOP), Morus alba L. polysaccharide (MLP) and Lycium barbarum polysaccharide (LBP) in T2DM mouse model. Among the three, MLP exhibited the most pronounced therapeutic efficacy, markedly alleviating hyperglycemia, insulin resistance, hepatic steatosis, and pathological lesions in the liver, pancreas. Liver metabolomic profiling revealed that MLP significantly modulated key glucose and lipid metabolic pathways, particularly bile acid and glycerolipid metabolism. Furthermore, we found MLP exerted its antidiabetic action through inhibition of the mTORC1 signaling pathway, leading to suppressed lipogenesis and enhanced fatty acid oxidation. Notably, MLP-mediated mTORC1 inhibition activated the PPARα–SIRT1 axis, thereby downregulating FOXO1-driven gluconeogenesis and promoting GLUT4-mediated glucose uptake. These findings suggest that MLP exerts comprehensive antidiabetic effects by targeting mTORC1-mediated metabolic reprogramming, offering promise as a natural therapeutic agent for T2DM.

The exploration of effective biocontrol agents and the characterization of their functional components are crucial for precisely preventing and managing carrot postharvest disease. Herein, Aspergillus niger xj was shown to effectively inhibit the bacterial soft-rot pathogen named Pectobacterium aroidearum , with the functional compounds primarily localized in the extracellular fermentation broth. Correlation analysis between the inhibitory activity and content of 5-hydroxymethyl-2-furancarboxylic acid (HMFCA) across 224 atmospheric and room-temperature plasma mutant strains and original strain xj indicated that HMFCA was an important inhibitory agent. The bioactivity of the bio-derived HMFCA isolated from the positive mutant strain 350–28 was validated through assays. In vitro inhibitory assays revealed that the half-maximal effective concentration (EC 50 ) of HMFCA against P. aroidearum was 1121 ± 8 μg mL −1 , with a minimum inhibitory concentration of 1.25 mg mL −1 and a minimum bactericidal concentration of 2.5 mg mL −1 . Moreover, HMFCA exhibited considerable potential to impede the growth of P. aroidearum . Furthermore, in vivo inhibitory assays indicated that HMFCA could assist carrot in resisting the infection caused by P. aroidearum within 24 h at three concentrations: EC 20 , EC 50 , and EC 80. However, the required effective concentration markedly increased at 48 h. These findings indicated that A. niger exhibited biocontrol activity through the extracellular secretion of active secondary metabolites, which directly suppressed the growth and reproduction of P. aroidearum . In particular, HMFCA was a functional compound, which offered a promising approach for the targeted postharvest management of carrot.

The cyclic capacity and cyclic loading of mixtures of 1,4-Butanediamine (BDA) and 2-(Diethylamino)-ethanol (DEEA) with different concentrations were compared using a fast screening facility. The biphasic solvent, 2 M BDA blended with 4 M DEEA, was found to have higher cyclic capacity and loading than other concentrations and 5 M MEA. The individual amine distributions in the upper and lower phases were measured by DX-120 ion chromatography (IC), with a formation mechanism then proposed for the biphasic solvents and verified with solubility experiments. The reaction products in the two phases were measured by a JNM ECA-600 nuclear magnetic resonance spectrometer (NMR).

Defects in perovskite solar cells (PSCs) critically hinder both device stability and power conversion efficiency (PCE). Incorporating multifunctional organic additives into the perovskite precursor offers a promising approach to overcome these limitations. Here, we report methyl 2-aminobenzoate (MA) as a novel multifunctional additive containing –COOCH 3 , –NH 2 groups, and a benzene ring. The benzene ring enhances hydrophobicity, while the ester (–COOCH 3 ) functional group, through its carbonyl oxygen and the –NH 2 group, coordinates with undercoordinated Pb 2+ ions, thereby effectively passivating Pb-related defects. Consequently, MA-modified PSCs deliver a PCE of 16.85 %, markedly higher than the 14.09 % achieved by the control devices. Moreover, the optimized devices retained 88 % of their initial efficiency after 700 h of continuous illumination at 25 °C under ambient air, underscoring their excellent long-term operational stability.

Bis(2-ethylhexyl) phosphate (HDEHP) was introduced as a novel collector for the flotation separation of cassiterite from quartz. Under the optimized flotation conditions (pH 8.0±0.2, HDEHP concentration of 15.0×10 -5 mol/L), a cassiterite concentrate assaying 74.01% SnO 2 was obtained with a recovery of 94.63%, demonstrating excellent separation performance. Compared with benzohydroxamic acid (BHA), HDEHP exhibited superior selectivity over a broader pH range. The adsorption mechanism was systematically investigated through contact angle measurements, zeta potential analysis, FTIR, XPS, ToF‑SIMS, AFM, and DFT calculations. The results indicate that HDEHP chemisorbs onto the cassiterite surface primarily via its PO(OH) groups, which coordinate with surface Sn sites to form a stable hydrophobic layer. In contrast, its interaction with quartz remained weak. DFT simulations further revealed that electron transfer and orbital hybridization occur between the oxygen atoms of HDEHP and surface Sn atoms, leading to stable chemical bonding and enhanced adsorption. Consequently, due to its strong and selective adsorption on cassiterite, HDEHP serves as an effective collector for the flotation separation of cassiterite from quartz.
