Ionic liquids (ILs) show great potential for carbon dioxide (CO2) capture due to their designable structures and dual roles as absorbents and catalysts. Our previously designed IL solvent ([Cho][Triz]/TMS) showed good absorption performance but a slow regeneration rate. Here, a novel strategy to promote CO2 desorption in IL absorbents at lower temperatures using homogeneous Lewis acid IL (LAIL) catalysts was proposed. The cobalt (Co)-based LAIL [Bmim]2[CoCl4] exhibited superior performance, with the CO2 desorption amount enhanced by 54.1% and activation energy reduced by 30.3% compared with the blank test, leading to low regeneration energy consumption (0.90 GJ/t CO2), which was ascribed to a simultaneous increase in Brønsted and Lewis acid sites, promoting C–N bond cleavage by C2–H in [Bmim]22+ and Co sites in [CoCl4]2–. The environmental impact of IL-based CO2 capture processes, evaluated by the green degree method, demonstrated that the green degree production value of the IL-LAIL system is 79.6 and 673.6 gd/h higher than that of the IL and MEA systems, respectively, indicating greater environmental sustainability. This study provides a viable strategy for employing homogeneous catalysts to facilitate energy-efficient CO2 capture.

Upconversion luminescence (UCL) of chiral inorganic nanostructured composite material and their applications have been challenging. This paper reports a successful preparation of Er 3+ /Yb 3+ co-doped chiral inorganic nanostructured BiOCl/Zn composite material (D-BYE-Zn) using a hydrothermal method and subsequent air annealing. The D-BYE-Zn phosphor significantly increased the intensity of UCL compared with the Er 3+ , Yb 3+ co-doped achiral bismuth oxychloride phosphor (A-BYE) and chiral bismuth oxychloride phosphor (D-BYE). Our study suggests that free electron leaps from the Zn fraction onto BiOCl may be responsible for the enhanced UCL. In addition, the temperature sensitive behavior of the D-BYE-Zn phosphor has been evaluated using the thermally coupled levels (TCLs) and non-thermally coupled levels (NTCLs) of Er 3+ and the maximum relative sensitivities (S R ) obtained are 0.95 % K −1 and 1.65 %K −1 (323 K). Our work provides a new strategy for constructing rare-earth doped chiral inorganic nanostructured composite materials to realize UCL enhancement while promising a wide range of applications in light source temperature measurement.

Bacterial resistance has seriously threatened public health security, high-entropy alloys (HEAs) present an unprecedented opportunity for the removal of drug-resistant bacteria due to their unique cocktail effect and tailorable physicochemical properties. Based on this, Zn–Fe–Mo–Co–Ni HEA (ZFMCN) is proposed as an antibacterial strategy against drug-resistant bacteria owing to the released antibacterial ions and near-infrared (NIR) light activated ROS generation. In vitro antimicrobial experiments demonstrated that ZFMCN can effectively eliminate the drug-resistant Escherichia coli ( EIEC ) and the methicillin-resistant Staphylococcus aureus (MRSA) by virtue of its ability to release antimicrobial ions and generate reactive oxygen species (ROS) under NIR irradiation with antibacterial rates of 92.81 ± 1.54% ( EIEC ) and 98.52 ± 1.22% (MRSA) respectively. Meanwhile, ZFMCN also has favorable cytocompatibility. Thus, we have developed a ZFMCN alloy that demonstrates potential as a promising antimicrobial agent against drug-resistant pathogens, while also establishing a foundation for subsequent research on promoting tissue healing.

The neuroinflammation plays a crucial role in the pathogenesis and progression of depression. Microglia serve as the principal source of neuroinflammatory factors and regulate neuroinflammation via M1 and M2 polarization phenotypes. Moreover, NOD like receptor protein 3 (NLRP3) inflammasome pathway is considered to be important in regulating pro-inflammatory cytokine release in the hippocampus. Zinc supplementation has been shown to effectively alleviate depressive symptoms in patients. In this study, we utilized a lipopolysaccharide (LPS)-induced mouse model of depression and LPS-activated BV-2 cells to examine the impact of zinc supplementation. The findings indicated that zinc supplementation could: (1) ameliorate the depressive-like behaviors of the mouse model with inhibition of inflammatory cytokines and zinc homeostasis recovery. (2) induce the polarization of microglia towards the M2 phenotype in vivo and in vitro. (3) suppress the activation of the NLRP3 inflammasome pathway by impeding the expression of P2X purinergic receptor 7 (P2 × 7) induced by LPS, thereby regulating microglial polarization. This may represent a crucial pathway via which zinc inhibits the M1 polarization of microglia, promotes polarization towards the M2 phenotype, thus improving neuroinflammation and exerting an antidepressant effect.

Thallium (Tl) and its compounds pose significant environmental risks due to their high toxicity and bioaccumulative potential, with industrial discharge standards mandating Tl concentrations below 5 μg/L. This study addresses the underexplored challenge of removing trace Tl(I) (≤1 mg/L) by investigating the efficacy of zinc sulfide (ZnS) as an adsorbent. Batch experiments, complemented by kinetic analyses (pseudo-second-order model), isotherm studies (Langmuir model, Qmax = 34.7 mg/g), and multi-technique characterization, were conducted to evaluate adsorption performance. Results show that ZnS achieves >99.9 % removal of trace Tl(I) at pH 10, reducing effluent concentrations to <0.4 μg/L—well below regulatory limits. Mechanistic investigations reveal a synergistic pathway: electrostatic attraction to negatively charged hydroxylated ZnS surfaces (zeta potential = −15.4 mV at pH 10), surface complexation via ≡ Zn-O-Tl bonds, and gradual formation of crystalline Tl₂S precipitates over prolonged contact. A two-stage treatment strategy, integrating sodium sulfide precipitation with ZnS adsorption, effectively purifies real-world matrices, including Tl-contaminated rainwater (Tl(I) from 352 μg/L to 0.440 μg/L) and high-salt industrial effluent (Tl(I) from 55.0 mg/L to 0.330 μg/L). This work provides experimental evidence for ZnS as a viable adsorbent for trace Tl(I) remediation, supporting the development of cost-effective heavy metal removal technologies.

The precise manipulation of the pore structure of carbon electrode materials at the atomic level is crucial for achieving ultra-fast charge and discharge in high-power supercapacitors. In this study, a novel strategy based on a trace amount of potassium ion (K + ) template-mediated liquid-liquid interface activation is developed. Using light bio-oil as the precursor, this method exploits the directional aggregation effect of its oxygen-rich macromolecules on the K + activating agent surface, successfully producing carbon materials with a high specific surface area (2044.4 m 2 /g), large pore volume (1.13 cm 3 /g), and high microporosity (97 %). The optimal carbon material demonstrates excellent electrochemical performance in aqueous supercapacitors: specific capacitances of 234.4 F/g and 434.5 F/g are achieved at 0.1 A/g in 6 M KOH and 0.25 M K 2 SO 4 electrolytes, respectively. Even after a 1000-fold increase in current density, 63.2 % of the initial capacitance is retained, demonstrating exceptional rate capability. Notably, the amount of activator used in this method is reduced by 27 times compared to traditional processes (activator/precursor ratio decreased from 3:1 to 1:9). Furthermore, comprehensive characterization techniques are employed to elucidate the chemical properties of light bio-oil and the pore-forming mechanism through activation with a low ratio of K + templates. The transport properties of different electrolyte ions within the pore structure of the synthesized carbon materials are also revealed. Particularly, the carbon electrode materials demonstrate exceptional cycling stability, maintaining nearly 100 % of their initial specific capacitance after 51,000 charge-discharge cycles at 10 A/g. This innovative liquid-liquid activation strategy, which achieves both high porosity and outstanding electrochemical performance in carbon materials using minimal activating agents, holds significant implications for the valorization of bio-oils.

Zn alloy engineering has emerged as a promising anodic strategy for aqueous Zn-ion batteries (AZIBs), effectively suppressing side reactions and dendritic growth. However, the impact of multiphase alloy compositions on zinc deposition and overall battery stability remains insufficiently understood. In this study, a versatile deep eutectic solvent (DES) was employed as both the electrolyte and the reaction medium for multiphase alloy formation. Hierarchically porous Cu-Zn multiphase alloys were fabricated on a three-dimensional (3D) Cu foam substrate (Cu-Zn/CF) via electrochemical deposition, with precise control over alloy composition achieved by adjusting deposition parameters. The synergistic interactions among Cu-Zn alloying elements significantly enhance the hydrogen evolution overpotential, reduce corrosion current, and effectively suppress Zn dendrite formation during repeated cycling. Furthermore, the combination of Cu-Zn alloys with the 3D Cu foam architecture facilitates highly reversible zinc plating and stripping processes. Consequently, the Cu-Zn/CF anode demonstrates exceptional cycling stability, maintaining performance for over 4000 h at 0.5 mA·cm −2 (0.5 mAh·cm −2 ). Notably, the anode retains excellent cycling stability with minimal polarization and an average Coulombic efficiency of 99% even under rigorous operating conditions. This work not only clarifies the functional roles of alloying components but also presents a novel strategy for the development of stable, dendrite-free zinc metal anodes.

Addressing the persistent bottlenecks of low efficiency, high costs, and complex fabrication in large-scale oil-in-water emulsion separation, especially for submicron emulsions where environmental compatibility and performance further degrade, this work introduces a cost-effective, biomass-derived separation layer, a straw-based gel membrane (SBGM), that emphasizes green design and functional integration. Fabricated via simple straw pretreatment and surface modification under solvent-free conditions, the SBGM is produced through an entirely green and straightforward route: one-step regeneration of straw cellulose to form gel spheres and a supporting matrix, followed by surface coating with a blended PVA/TiO 2 functional layer. Featuring a lotus-leaf-inspired bionic structure and abundant hydrophilic groups, the membrane exhibits superhydrophilicity (WCA = 0°) and underwater superoleophobicity (UOCA = 162°), together with exceptional durability and stability against acids, alkalis, and extracellular polymers in wastewater. Critically, it delivers over 99 % separation efficiency across diverse submicron oil-in-water emulsions and maintains stable performance over repeated cycles, with a flux recovery rate of approximately 90 % and a fouling deposition ratio of approximately 30 %. Moreover, the photosensitive properties of TiO 2 confer superior hydrophilicity and self-cleaning capability, enabling the SBGM to sustain over 99 % separation efficiency even when treating real kitchen wastewater. Collectively, these advances markedly enhance the SBGM's practical potential for submicron oil-in-water emulsion separation.

Accurate identification of multiple teas based on the difference in their contents and species of metal ions is vital in food inspection and public health. However, achieving accurate sensing from one material with various transduction signals and excellent anti-interference remains a challenge. Herein, a four-channel sensing platform was constructed by combining with four water-soluble InP/ZnS QDs with independent emission. The fluorescence intensities of the four water-soluble InP/ZnS QDs change in different degrees owing to the synergistic coordinative effect between metal ions and ligands. Interestingly, the multi-channel sensing platform allows the qualitative performance of metal ions with excellent anti-interference, high sensitivity, and high accuracy in binary and ternary mixtures. Moreover, the multi-channel fluorescent array exhibited a universality-powerful capability for identifying five teas with satisfactory results. The universal application for detecting Cr 6+ , Hg 2+ , and Cu 2+ in various tea drinks was demonstrated with excellent recovery, indicating a promising potential application in food safety.

Rare earth-doped luminescent materials typically produce characteristic fluorescence emissions associated with the rare earth elements. Here, we report remarkable non-characteristic blue emissions from ytterbium (Yb 3+ )- and erbium (Er 3+ )-doped organic-inorganic metal halides, (BDPA) 2 MCl 4 (BDPA + = benzyldimethylphenylammonium; M 2+ = Cd 2+ , Zn 2+ ). Both Yb 3+ and Er 3+ ions are commonly used as dopants in phosphors, which generally lead to near-infrared emissions. Theoretical calculations suggest the unique blue emission arises from Yb 3+ /Er 3+ -induced exciton radiative recombination from BDPA + to Cl − , which suppresses the characteristic emissions of these rare earth ions. More notably, owing to structural stability of (BDPA) 2 MCl 4 , the Yb 3+ /Er 3+ -activated phosphors demonstrate high water resistance, maintaining both stability and photoluminescence (PL) in water for over two months. Further, when these crystals are dissolved in N,N-dimethylformamide or dimethyl sulfoxide, the resulting solution continues to exhibit PL with a high quantum yield of ~90%, making it suitable for use as liquid-phase X-ray scintillators.

Tetracycline (TC), as a persistent and widely detected antibiotic pollutant, poses severe ecotoxicological risks and necessitates rapid and efficient degradation strategies. Here, we demonstrate a photocatalytic self-Fenton process in which H 2 O 2 produced via visible-light-driven oxygen reduction is directly activated by Fe species for the rapid degradation of TC. To enable efficient H 2 O 2 production, a ternary ZnIn 2 S 4 / CdIn 2 S 4 /MnIn 2 S 4 (denoted as ZC 0.3 M 0.05 ) heterojunction photocatalyst was rationally constructed via a one-pot hydrothermal method. Structural analyses reveal that the three sulfides form a tightly coupled, multi-interfacial nanoscale architecture that induces pronounced interfacial strain and charge polarisation. Consequently, ZC 0.3 M 0.05 delivers a high H 2 O 2 production rate of 4907.7 μmol g⁻ 1 h⁻ 1 , outperforming pristine ZnIn 2 S 4 , CdIn 2 S 4 and MnIn 2 S 4 by factors of 15.2, 10.7 and 13.6, respectively. Upon Fe addition, the in situ generated H 2 O 2 enabled rapid self-Fenton degradation of TC, achieving 91.9 % removal within 5 min, while maintaining high activity under simulated environmental conditions. Combined spectroscopic, electrochemical and theoretical analyses reveal that work-function-difference-driven and stepwise electron-transfer pathways (MnIn 2 S 4 → ZnIn 2 S 4 → CdIn 2 S 4 ) across multiple heterointerfaces facilitate efficient charge separation and O 2 -to-*O 2 ⁻ electron injection. This work establishes a materials framework for on-demand H 2 O 2 production and direct self-Fenton pollutant remediation, and offers general design principles for high-performance ternary metal sulfide heterojunctions.

Addressing water scarcity and pollution in underdeveloped regions requires safe water production from inferior sources. Solar-driven interfacial evaporation (SDIE) coupled with photocatalysis offers great potential for this challenge. Herein, a dual-functional composite (BTG@MS) was fabricated by immobilizing oxygen vacancy- and Ti(III)-rich black TiO 2 /defective g-C 3 N 4 (BTG) on melamine sponge (MS) hydrogel. The composite broadens light absorption to 300–1200 nm (80.7% average absorption efficiency) and forms a type-II heterojunction, facilitating charge separation and reactive oxygen species (ROS) generation. Benefiting from MS’s hierarchical water transport pathways and BTG’s enhanced solar utilization, BTG@MS exhibits outstanding dual performance under one-sun illumination (1 kW/m 2 ), an evaporation rate of 1.26 kg/(m 2 ·h) (74.3% photothermal efficiency) and 84.5% tylosin (TYL) degradation efficiency. It also shows salt tolerance and effectiveness in purifying four types of water sources, producing clean water meeting WHO standards. This work presents an innovative strategy integrating photothermal evaporation and photocatalysis, promising practical application in tackling the water crisis in underdeveloped regions.
