Solar Insecticidal Lamps Internet of Things (SIL-IoTs), used for green agriculture, face theft and destruction due to high costs. To address this, we introduce SILC nodes by embedding cameras in SIL nodes, forming SIL-IoVTs for pest control and intruder monitoring. SIL-IoVTs involve omni-directional (SIL) and directional (camera) sensing models for area and target coverage. We formulate an optimal deployment model and develop a bi-level algorithm to solve it, iteratively deploying SIL nodes for pest control and cameras for monitoring. Simulation results show the method's effectiveness and progressiveness.

Uranium as a crucial ingredient for nuclear reaction, has provided a risk to the environment and human safety due to its chemical toxicity and radioactivity. Monitoring and management of uranium contamination are of great significance for the rational utilization of uranium resources and the maintenance of the environment. Herein, we fabricated a novel fluorescent covalent organic framework (COF-AO) with multifunctional groups via facile Schiff base condensation and amidoximation reactions for selective uranium detection and extraction simultaneously. COF-AO featured a short adsorption equilibrium time of 45 min and a high saturated adsorption capacity of 229.9 mg/g, leading to a fast adsorption rate (5.1 mg g-1 min-1). Meanwhile, COF-AO demonstrated excellent uranium selectivity and an ultra-low fluorescence detection limit (14.6 nM). Furthermore, COF-AO displayed exceptional adsorption capacities in different natural water samples. Notably, the uranium extraction capacity of COF-AO from natural seawater was 16.0 mg/g in 28 days, indicating a high utilization rate of the COF-AO active sites in low-concentration solutions. Our work provides an effective strategy for designing fluorescent COF materials aimed at uranium detection and capture, which may be expanded to the detection and extraction of other pollutants through the rational design of specific ligands. © 2025, The Authors.

Coprecipitation of phosphate in calcium carbonate minerals is a ubiquitous geochemical phenomenon in marine sedimentation and cave stalagmite formation, however, it is not clear whether phosphate is incorporated into the calcite structure. In this research, we applied solid-state nuclear magnetic resonance (NMR) spectroscopy to analyze P speciation during coprecipitation with calcite. The ³¹P NMR results show three peaks with chemical shifts of 3.9, 3.0 and −1.0 ppm, indicative of at least three phosphate species in the coprecipitates. Combined with advanced ³¹P{¹H} cross-polarization (CP)/MAS, ¹H DE/MAS, ³¹P{¹H} 2-d heteronuclear correlation (HetCor) and ³¹P{¹³C} cross-polarization rotational echo double resonance (CP-REDOR) NMR experiments, the 3.9 ppm peak can be tentatively assigned to calcite structural defects as amorphous calcium phosphate (ACP)-like environments while the 3.0 ppm peak arises from a carbonated hydroxyapatite (CHap). The ³¹P NMR peak at −1.0 ppm can be assigned to structurally incorporated phosphate in the calcite crystals in the form of HPO₄²⁻. Nano secondary ion mass spectrometry (NanoSIMS) and high-resolution scanning transmission electron microscopy (HR-STEM) analysis further suggests that the incorporated HPO₄²⁻ substitutes for the structural carbonate group (CO₃²⁻) of calcite. However, the local expansion stress field generated with HPO₄²⁻ incorporation in the calcite structure prevents PO₄/CO₃ isomorphous substitution and favors the precipitation of calcium phosphates. The findings of this study not only provide deep insights into carbonate crystal chemistry but also shed light on the application of carbonate materials as potent geochemical proxies in paleoenvironmental reconstructions. © 2025 Elsevier Ltd

In this work, the advantageous mesoporous CeO2 nanosphere with large specific surface area up to 190.4 m2/g was facilely prepared using an improved hydrothermal method. The obtained mesoporous CeO2 nanosphere was used as the support for Ni-based CO2 methanation catalysts. The effects of Ni loading, structural properties, and redox characteristics on the catalytic performances were systematically investigated. The catalyst with 20 wt% Ni loading supported on mesoporous CeO2 nanosphere demonstrated exceptional low-temperature activity. A comprehensive suite of characterization techniques, including XRD, N2 physisorption, SEM, XPS, H2-TPR, CO2-TPD, in-situ DRIFTS, and online TPSR, were utilized to elucidate the underlying reasons for the superior performance. The superior activity of the Ni-based catalyst was attributed to the large specific surface area, mesoporous structure, and excellent redox properties of the mesoporous CeO2 nanosphere support. In contrast, Ni-based catalysts supported on commercial materials (e.g., SiO2, Al2O3, CeO2) exhibited poor low-temperature performance due to severe thermal sintering of metallic Ni active sites and inferior redox properties. Therefore, the present mesoporous CeO2 nanosphere with large specific surface area, advantageous redox property, and abundant surface oxygen vacancies are promising supports for Ni-based catalysts, enhancing low-temperature CO2 methanation performance and potentially benefiting other reactions. © 2025 Elsevier Ltd and Techna Group S.r.l.

Atomic-level catalysts are extensively applied in heterogeneous catalysis fields. However, it is a general but ineluctable issue that active metal atoms may migrate, aggregate, deactivate, or leach during reaction processes, suppressing their catalytic performances. Designing superior intrinsic-structural stability of atomic-level catalysts with high activity and revealing their dynamic structure evolution is vital for their wide applications in complex reactions or harsh conditions. Herein, high-stable Pd─Cu dual-atom catalysts with PdN3─CuN3 coordination structure are engineered via strong chelation of Cu2+-ions with electron pairs from palladium-source, achieving the highest turnover frequency under the lowest overpotential for Cr(VI) electrocatalytic reduction detection in strong-acid electrolytes. In situ X-ray absorption fine structure spectra reveal dynamic "spring-effect" of Cu─Pd and Cu─N bonds that are reversibly stretched with potential changes and can be recovered at 0.6 V for regeneration. The modulated electron-orbit coupling effect of Pd─Cu pairs prevents Cu-atoms from aggregating as metallic nanoparticles. Pd─Cu dual-atoms interact with two O atoms of H2CrO4, forming stable bridge configurations and transferring electrons to promote Cr─O bond dissociation, which prominently decreases reaction energy barriers. This work provides a feasible route to boost the stability and robustness of metal single-atoms that are easily affected by reaction conditions for sustainable catalytic applications. © 2025 The Author(s).

Sand biofiltration is widely utilized to remove undesirable substances, such as divalent manganese [Mn (II)] and ammonium (NH4+), from water resources. Long-term consumption of water with pollutants, notably excessive Mn(II), would result in lower neuropsychological performance and hyperactivity behaviors in children. While sand biofiltrations have been extensively inplemented for pollutant removal, their operational effeciency is contstrained by the long startup periods. This study evaluated Mn(II) and NH4+ removal in two sand biofilters, one with NH4+ (named NB) and one without (named MB) under different inoculum conditions, over 310 days of operation. Biofilters inoculated with sediments showed Mn(II) removal rates of 15.7 % (MB) and 9.0 % (NB), respectively, with no NH4+ removal observed. After adding activated sludge (AS), Mn(II) removal increased to 56.3 % and 37.5 %, and NH4+-N removal reached 38.3 %. AS significantly improved removal efficiency and shaped microbial community structure. Linear discriminant analysis (LDA) effect size (LEfSe) analysis identified various key microorganisms, including Sphingomonas, Bradyrhizobium, Rhizobacter, Pedomicrobium, and Legionella, significantly proliferated post-AS inoculation. Spearman correlation indicated Acidobacteriota was positively correlated with Mn(II) removal, while Nitrospirota was linked to NH4+ removal. Apart from Pedomicrobium, several unclassified species might be associated with the Mn(II) removal process. The amplicon sequencing combined RT-qPCR results indicated enhanced NH4+ oxidation at the early stage of the biofilter ripening, attributed to the rapid enrichment of comammox Nitrospira. The study highlighted the importance of inoculum selection in achieving efficient biofilter startup. © 2025

The necessity for safe and effective alternatives to conventional chemical fungicides is underscored by postharvest citrus fruit losses due to anthracnose, caused by Colletotrichum gloeosporioides. In this context, the biocontrol fungus Bipolaris bicolor WZU-HOG4, isolated from Ougan pericarp, was identified as possessing antimicrobial activity. Through bioassay-guided fractionation and subsequent metabolite profiling, N-Acetyl-O-methyl-tyrosine was identified as the active antifungal compound using NMR and HRESIMS. This compound demonstrated significant inhibitory effects against C. gloeosporioides and other pathogens, exhibiting a relatively broad-spectrum antifungal activity. Molecular docking analysis indicated that N-acetyl-O-methyl-tyrosine binds to tyrosinase with greater affinity than Vitamin C, effectively inhibiting its activity. Furthermore, Ougan fruits treated with the compound exhibited increased activities of antioxidant enzymes SOD, POD, and CAT, reduced MDA content, and decreased oxidative stress during storage. Cytotoxicity assays conducted on HEK-293 cells confirmed the compound's safety at the tested concentrations. N-acetyl-O-methyl-tyrosine emerges as a promising natural antifungal and tyrosinase inhibitor for citrus postharvest preservation, providing a safe alternative to chemical preservatives for extending shelf life. © 2025, The Authors.

The sulfur content of blast furnace gas has an impact on its utilization, which makes the deep desulfurization of blast furnace gas a necessity. In the present study, aluminum-based core-shell microsphere catalysts were synthesized using aqueous method for catalytic removal of COS and H2S. The Cu-Ce@Al2O3 is more conducive to the generation of oxygen vacancies. The distinctive core-shell configuration presents a multitude of active sites, thereby reducing the competitive adsorption of H2S and COS on the catalyst surface. The presence of Cu2+ species is of particular significance, as it serves to facilitate the hydrolysis of COS and the simultaneous removal of H2S. The Ce3+ species facilitates the oxidation of the S species, thereby enhancing the desulfurization effect. The Al2O3 protective shell prevents the Cu-Ce active component from being covered by sulfur deposition, thereby maintaining its reactivity. The addition of Al2O3 as a shell can enhance the alkalinity of the catalyst, facilitating the adsorption of COS and H2S on the surface and, in turn, improving the catalyst's reaction activity. The core-shell structure proved more conducive to promoting the redox capacity of Cu+/Cu2+ and Ce4+/Ce 3+. CuO (110) represents the primary active center of the COS hydrolysis reaction, yet it also leads to over-oxidation of H2S. In contrast, CeO2 was conductive to the formation of HSCOOH and S0. CuO, on the other hand, was favorable to the dissociation of HSCOOH and the oxidation of S0. © 2025 Chongqing University

Ceiling beams at the top of tunnels are more common in actual projects. Under the influence of thermal buoyancy, the ceiling structure significantly affects the diffusion characteristics of fire smoke within the tunnel. This study investigated the influence of ceiling structural characteristics (beam height $(h_{\mathrm{B}})$ and beam spacing $(d_{\mathrm{B}}))$ on tunnel longitudinal ventilation through numerical simulation. The results show that the spacing between tunnel ceiling beams has negligible impact on the critical velocity (V), and the determination of the critical velocity is primarily correlated with the height of the ceiling beams. Moreover, it established a dimensionless critical velocity $(V_{\mathrm{c}})$ model for the tunnels with multiple beams in the ceiling, and this model is suitable for predicting the critical longitudinal velocity of tunnels with ceiling beams whose dimensionless beam height is less than 0.25. When the dimensionless beam height exceeds 0.25, the predictive values of this model are excessively high. This study broadens the application scope of fire smoke control models, which can offer technical support for the design of smoke prevention and exhaust systems in tunnels with similar structures.
