Rechargeable zinc-air batteries (ZABs) are attractive for energy storage, but their efficiency is limited by the slow kinetics of the oxygen reduction reaction (ORR) and oxygen evolution reaction (OER). Here, we report a bifunctional single-atom catalyst consisting of atomically dispersed iron anchored on N-doped two-dimensional (2D) carbon nanosheets (Fe-NCS-800) for high-performance ZABs. This material was sustainably synthesized through the graphene-oxide (GO)-induced hydrothermal carbonization of hemicellulose, followed by copyrolysis with NH4Cl and FeCl3 and subsequent acid leaching. The resulting architecture comprises interconnected porous nanosheets with a substantial surface area (1436 m2 g–1), facilitating mass transport and exposing abundant active sites. Advanced characterization techniques, including aberration-corrected scanning transmission electron microscopy (AC-STEM) and X-ray absorption spectroscopy, confirmed the dominant presence of FeN4 coordination sites. Under alkaline conditions, Fe-NCS-800 outperformed Pt/C in the ORR with a half-wave potential (E1/2) of 0.87 V vs RHE, while also exhibiting appreciable OER activity, resulting in a low bifunctional index (ΔE) of 0.83 V. When used as the air cathode in Zn-air batteries, it reached a peak power density of 215 mW cm–2 and a specific capacity of 766 mA h g–1, maintaining stable operation for over 400 h. These results show a sustainable strategy for developing efficient biomass-derived single-atom electrocatalysts for next-generation metal-air batteries.

Nanomotors are appealing drug carriers with deep tissue penetration to overcome biological barriers. Though high motion efficiency has been achieved with NIR-II light driven nanomotors, insufficient directional control and material biocompatibility limit their broad application. Herein, leveraging commercially available liposomal doxorubicin (DOX) as a platform, we develop a magnetic-steering NIR-II light thermophoretic liposomal nanomotor (LipNM) by asymmetrically incorporating magnetic photothermal Fe 3 O 4 @Cu 9 S 8 nanoparticles into the lipid bilayer, firstly realizing directional nanoscale self-thermophoresis. The embedded Fe 3 O 4 @Cu 9 S 8 nanoparticles respond to a brief magnet stimulation for spatiotemporal steering and NIR-II irradiation with local temperature increase for self-thermophoresis of LipNMs, which further facilitate tumor tissue targeting and deep tumor penetration, respectively. The direction-controllable thermophoretic LipNMs demonstrate good biocompatibility and increase the delivery efficiency of DOX by 186% compared to passive liposomal doxorubicin. Owing to the targeted accumulation and deep tissue penetration at the tumor site, the therapeutic efficiency of LipNMs for breast cancer in vivo is as high as 94.9%, providing a promising strategy for cancer therapy.

To address cadmium pollution in water bodies, a novel N-doped red mud-biochar magnetic composite (N-RCB) was prepared through one-step co-pyrolysis of corn stover and red mud at 800 °C, using ammonium chloride as a pore-forming agent and urea as a nitrogen source. The obtained N-RCB was applied for the efficient removal of Cd 2+ from aqueous solutions. The equilibrium adsorption capacity of N-RCB for Cd 2+ was 5.0 times and 4.2 times that of the pristine biochar (CB) and non-N-doped magnetic red mud-biochar (RCB), respectively. The maximum theoretical adsorption capacity of N-RCB for Cd 2+ could reach 473.25 mg·g –1 . Adsorption kinetics and isotherm studies indicated that the adsorption process of Cd 2+ onto N-RCB followed the pseudo-second-order kinetic model and the Freundlich isotherm model, suggesting that the process is dominated by chemisorption and heterogeneous multilayer adsorption. The thermodynamic parameters demonstrated that the adsorption process was spontaneous, endothermic, and driven by an increase in entropy. The adsorption mechanisms of Cd 2+ by N-RCB included pore filling, cation-π interactions, surface complexation, and electrostatic attraction. Coexisting ion experiments further demonstrated that N‑RCB exhibited good anti‑interference ability toward common ions such as K + , Na + , Mg 2+ , NO₃⁻, and Cl⁻. In addition, after five consecutive adsorption–desorption cycles, the removal efficiency of Cd 2+ by N-RCB remained above 88 %. These results indicate that N-RCB is a promising green and efficient material for the removal of Cd 2+ from water bodies, demonstrating significant application potential.

Urea is a nitrogenous fertilizer characterized by high water solubility, yet it suffers from a relatively low nitrogen utilization efficiency. It not only pollutes the environment but also reduces agricultural productivity. Developing the physicochemical properties of nitrogen fertilizers is the key to improve the nitrogen utilization efficiency. In the present investigation, a novel 1:1 urea-ammonium chloride co-crystal system was synthesized through solvent evaporation methodology. This co-crystallization approach aimed at optimizing the physicochemical characteristics of urea. The formation of cocrystal was confirmed by a variety of characterization techniques, including PXRD, and DSC, TGA, SEM, Raman spectroscopy, and the crystal structure and purity were verified. The spectral properties of the material were measured using the THz-TDS system, which can effectively characterize the formation of cocrystal. The crystal structures and theoretical THz spectra of urea, ammonium chloride and the corresponding cocrystal were simulated by using density functional theory calculations. The solubility of the synthesized cocrystal was evaluated under greenhouse conditions, and the cocrystal's urea solubility was 36.15 g/100 mL, a ~ 66% reduction from pure urea's 100–120 g/100 mL. This work provides valuable methodological insights for agricultural cocrystal development and highlights the potential of cocrystal urea as a slow-release nitrogen fertilizer.

This work aimed to prepare organo-montmorillonite (PB-MMT and PD-MMT, namely O-MMT) adsorbent with hydrophobic properties and hydrogen bond acceptor capacity via modification with Gemini surfactants (PB and PD), and to investigate the key role of long alkyl chains and amide bonds in the adsorption behaviors of 4-nitrophenol (4-NP) and 4-chlorophenol (4-CP) in aqueous solutions. The microstructure, morphology and surface propertie of O-MMT were explored by different techniques, including XRD, BET, SEM, FT-IR, TGA and Zeta potential. The results show that the saturated adding amount of PB and PD is 1.0 CEC, and PD with flexible alkyl spacer shows markedly higher loading amount (38.22 wt%) on Na-MTT than PB with rigid spacer (36.35 wt%). The batch experiment results of O-MMT to 4-NP and 4-CP demonstrate that the two are ranked by adsorption capacity as follow: PD-MMT > PB-MMT. Kinetic studies are found pseudo-second-order (R 2 > 0.99) and equilibrium data are fitted well by Freundlich isotherm model (R 2 > 0.99) which indicate the adsorption process is primarily multilayer adsorption. The calculated thermodynamic parameters exhibit that the adsorption processes of 4-NP and 4-CP on O-MMT are physical adsorption and exothermic. Adsorption mechanisms highlighted the synergistic effects of hydrophobic interactions and O-H···N hydrogen bonding as important design criteria for efficient removal of 4-NP and 4-CP from aqueous solutions.

Electrocatalytic conversion of nitrate to ammonia is a rapidly evolving field due to its potential applications toward nitrate pollution remediation and sustainable ammonia synthesis. As a group of well-established electrocatalysts, the activity of Cu-based materials is highly related to the coordination environment. Herein, a novel Cu–La-based dual-atom catalyst (Cu–La/DAC) was prepared using a Robson-type bimetallic Cu–La complex as precursor, where the square-planar Cu center of Cu–La/DAC effectively deviates due to the presence of adjacent La atom. As a result, the HOMO (dxy) energy of Cu is effectively reduced, which facilitates the formation of low-valent Cu and subsequent electrocatalysis. Compared to Cu2/DAC analogue containing square-planar Cu, Cu–La/DAC exhibits significantly enhanced activity toward electrocatalytic nitrate (NO3–) reduction to ammonia (NH3) (yield: 14.02 mg h–1 cm–2; Faraday efficiency: 88.42%), which is theoretically attributed to the reduced energy barrier of NO3– adsorption and *NO3 deoxygenation induced upon the coordination environment modulation of Cu.

Existing triboelectric nanogenerators (TENGs) for wearable sweat sensors are plagued by low power density, which restricts their practical application. This study focuses on boosting TENGs output power via a fluorinated bi-layer electronic textile (e-textile) fabricated by electrospinning rotary collection, enabling self-powered dual functionality: real-time electrochemical sweat sensing and human motion detection. The key design includes a PCLU-HFDD negative triboelectric layer (molecularly incorporated with hexadecafluorodecanediol to enhance electron affinity) and a poly(lactic- co -glycolic acid) (PLGA) positive layer. Rotary collection creates vein-like nanostructures on PCLU-HFDD yarns (6.2 μm roughness, 114.8° water contact angle), increasing contact area. The PCLU-HFDD TENG achieves a high power density of 0.66 W m −2 , an open-circuit voltage (Voc) of 117.08 V, and excellent stability over 35,000 contact-separation cycles. Critically, integrated with both sweat-sensing and motion-detection capabilities, the e-textile enables 180-min continuous glucose monitoring (under sedentary conditions) and recognition of human motions. This work confirms that the power enhancement not only overcomes the bottleneck of TENGs for wearable sensors but also facilitates dual-modal health monitoring, advancing the development of practical wearable bioelectronics.

Conventional urea industry faces dual challenges of high energy consumption and carbon emissions. Although electrochemical co-reduction of nitrates and carbon dioxide (CO₂) offers a promising route for green urea synthesis, its electrical-to-chemical energy conversion efficiency remains constrained by sluggish reaction kinetics and high electrical energy demand. Here, we design and report a nitrogen-doped porous carbon (NC) material embedded with dispersed copper‑nickel bimetal nanoparticles (CuNi/NC) for constructing the first example of a Zn-nitrate/CO₂ battery that can output electricity while generating urea with a superior energy efficiency of 1.51 mol urea kWh −1 and a urea production rate of 110 mg h −1 g cat −1 . The proposed assembled battery exhibits exceptional stability over 300 h , retaining high urea Faradaic efficiency at 36% and yield at 101 mg h −1 g cat −1 . In situ X-ray absorption spectroscopy, infrared spectroscopy, and density functional theory simulations confirm that the active metal sites facilitate substrate adsorption and stabilize critical intermediates (* N-C-N , *NH₂, and *NO), thereby effectively accelerating C N coupling. This work breaks the ‘high-energy, single-function’ bottleneck of traditional electrochemical systems, establishing an innovative ‘carbon-negative energy supply’ paradigm for carbon-neutral agriculture and decentralized energy systems.

The presence of fluoroquinolone antibiotic residues brings significant threats to food safety and human health. This situation has necessitated the development of rapid visual detection methods for identifying these residues in food products. This study constructed a self-calibrating ratiometric fluorescent sensor based on europium and deep eutectic solvent complex (Eu-DES) for the sensitive visual detection of levofloxacin (LEV). By mixing Eu 3+ with the DES (oxalic acid:choline chloride = 1:1) ligand at room temperature, a stable red fluorescence at 623 nm was successfully achieved in the Eu-DES system. Upon the addition of LEV, the Eu-DES induced a red-shift fluorescence of LEV, enabling a self-calibrating ratiometric fluorescent response to LEV with a wide linear range (0.5–100 μM) and a low detection limit (86.50 nM, S/N = 3). Furthermore, integrating Eu-DES into a gel matrix and combining it with smartphone-assisted RGB color analysis enabled quantitative LEV detection through multicolor shifts from red to green. This approach was successfully applied to detect LEV in honey and milk with high sensitivity and good recovery (92.7%–106.4%). The Eu-DES-based detection platform developed in this study provides a powerful tool for on-site LEV detection in actual food samples, promising to advance rapid food safety testing technologies.

Zn-Al-Mg powder co-diffusion was performed on Q235 steel using a mechanical energy-assisted diffusion process. The resulting ZAM alloy diffusion coating comprised an inner Fe Zn layer composed of δ(FeZn 10 ) and Γ(Fe 11 Zn 40 ) phases, while the outer layer exhibited a multiphase structure distributed discontinuously in island-like or dot-like patterns on the δ-phase surface. The multiphase structure exhibits layered characteristics extending outward from the δ phase: an Al-rich layer composed of Al 2 O 3 and Fe Al phases; a Mg-rich layer interwoven with Mg Al phases, Mg Zn phases, and MgO; and an amorphous ZnO layer. The growth mechanism is investigated by this study, revealing that during the primary co-diffusion phase, a 20 μm Fe Zn layer formed first on the substrate. Subsequently, increased Al atoms combined with Fe atoms within the Fe Zn phase to form an Fe Al layer, thereby inhibiting Fe Zn layer growth. Finally, active Mg atoms form a Mg-rich layer on the surface of the Fe Al layer. Mg-rich layer combines with Al atoms to form a Mg Al phase and induces lattice distortion, thereby inhibiting Fe Al layer growth. Throughout the process, the removal of HCl exposes the Fe Zn layer and restores its normal growth. Eventually, under this dynamic mechanism, a complex, multi-phase outer structure is formed. The self-corrosion current (J corr ) of the ZAM diffusion coating (1.673 × 10 −5 A/cm 2 ) markedly lower than the ZA diffusion coating (5.499 × 10 −5 A/cm 2 ). While the ZAM diffusion coating exhibited a weight gain of 1.182 ± 0.075 mg/cm 2 after 120 h of oxidation at 500 °C, which was slightly higher than the ZA diffusion coating but considerably lower than Q235 steel.

Diffusive Gradients in Thin-films (DGT) can be used as an effective supplement of the water pollutant monitoring. However, long-term application and verification of the DGT technique in nature waters have been limited due to the substantial effort required to compare DGT results with those obtained from grab sampling. This study compared the concentrations of a variety of trace elements and emerging organic contaminants (EOCs) measured using DGT and grab sampling method during long-term in field. The results show that the precision and accuracy of DGT can meet the technical requirements. The concentrations of selected trace elements, EOCs and phosphorus were determined in freshwater systems (six rivers and two lakes) across various cities and seawater systems (two sampling sites in Yancheng) during different seasons. The sources and seasonal variations of these pollutants were analyzed. The results show the concentrations of trace elements in the surface water of Nanjing and Yancheng were in the ranges of 0.010–8.97 and 0.010–47.1 μg L −1 , respectively. While the EOCs in the surface water of Nanjing and Yancheng changed within the range of 0.111–390 and 0.110–207 ng L −1 , respectively. Surface waters in Yancheng expressed lower EOC pollutant concentrations than the surface waters in Nanjing (except for PFOA, PFOS and OPFRs). During summer and autumn, the pollutant concentrations were lower than that during spring and winter (except for pesticides). Concentrations of NH 4 -N, NO 3 -N, and phosphorus were also measured via grab sampling and DGT for water quality assessment. The Predicted No-Effect Concentrations (PNECs) of the target trace elements and EOCs were calculated to evaluate the environmental risks of these substances on aquatic species. The levels of most target detected in this work did not appear to present risks to the aquatic species. However, a few substances showed moderate or high risk.

Plasma amplification laser-induced breakdown spectroscopy (Plasma amplification LIBS) has shown great potential in N elements in water due to high sensitivity, precision, and accuracy. To further reduce interferes of the atmospheric nitrogen, the effect of laser wavelength on the quantitative determination of nitrogen in water was investigated. With short laser wavelength, stronger spectral line intensity, lower interference from atmospheric nitrogen, and superior analytical performance were obtained. The linear coefficient of determination (R²) of the calibration curve improved from 0.2147 to 0.9732, the limit of detection (LOD) was reduced from 18.98 ppm to 3.41 ppm, and the spectral stability, expressed as average relative standard deviation (RSDAV), was reduced from 10.49% to 5.45%. Moreover, the average relative error (REAV) and the root mean square error of cross-validation (RMSECV) for the predicted concentrations were improved by approximately 56.82% and 71.79%, respectively. These results demonstrate that the 532 nm wavelength in plasma amplification LIBS can significantly enhance both the detection sensitivity and the accuracy of quantitative analysis for nitrogen in water.
