Given the scarcity of precious metals in nature and the high costs of extraction and refinement, their recovery holds significant practical importance. In this study, we employed an induced-defect strategy to prepare a novel metal-organic framework material, UiO-67-MAA, using a one-step solvent method that exhibited rapid adsorption kinetics and ultra-high adsorption capacity. In addition, the ability of the material to recover Au(III) from aqueous solutions was evaluated through systematic adsorption experiments. Various characterisation methods were employed to verify the successful synthesis and structural stability of UiO-67-MAA. The maximum adsorption capacity of UiO-67-MAA for Au(III) reaches 814 mg/g. In repeated experiments, the removal effect of UiO-67-MAA on Au(III) remained significant even after five cycles. The adsorption mechanism was analysed by X-ray photoelectron spectroscopy (XPS) and energy-dispersive X-ray spectroscopy (EDS), confirming that S atoms interact with Au(III) to form a stable coordination structure. These results indicate that UiO-67-MAA possesses efficient adsorption properties for Au(III), thus demonstrating its significant potential for application in precious metal recovery.

To address the challenge of removing high-concentration calcium and magnesium ions (Ca 2+ /Mg 2+ ) from seawater desalination brines (SDB), this study introduces a novel chitosan-based biochar aerogel (CBA) system specifically engineered for hypersaline water treatment. The innovative adsorbent material utilizes high-temperature pyrolysis chitosan (85 % and 95 % deacetylation degree (DD)) generate biochar and then crosslinked into three-dimensional porous aerogels (CBA85 and CBA95), which were compared with conventional activated carbon aerogel (ACA). Comprehensive characterization revealed that CBA95 exhibited a high density of free amino groups and a well-developed mesoporous structure, with a specific surface area of 107.04 m 2 /g, approximately 3.14 times that of ACA. The maximum adsorption capacities of CBA95 for Ca 2+ and Mg 2+ were 5.15 mg/g and 9.37 mg/g, respectively. Selectivity adsorption experiments demonstrated CBA95 exhibited high selectivity for Ca 2+ and Mg 2+ , with distribution coefficient ( K d ) of 164.25 mL/g and 42.73 mL/g, respectively. The equilibrium data were aligned with the Langmuir isotherm model, suggesting a monolayer chemical adsorption mechanism, and further the electrostatic and complexation adsorption mechanism was identified and proposed. Most notably, fixed-bed reactor of CBA95 maintains over 87 % of Ca 2+ and 91 % of Mg 2+ removal efficiency after 9 adsorption-desorption cycles. The pilot-scale experiment of CBA95 in Qingdao SDB achieved 72.3 % Ca 2+ and 74.6 % Mg 2+ removal, confirming high industrial potential. Thus, this research not only establishes a theoretical foundation for applying chitosan-based materials in SDB softening but also provides a solution for large-scale engineering-scale applications due to their environmental sustainability and potential.

Water electrovoltaic generation (WEG) technologies have emerged as a promising avenue for sustainable energy harvesting in response to the growing global emphasis on carbon neutrality. However, conventional WEG systems still encounter significant limitations, including high fabrication costs, limited environmental degradability, and susceptibility to ambient fluctuations. This study presents an aerogel wood-based water evaporation-induced generator (AW-WWEG) fabricated through simple chemical treatment of balsa wood (BW) without incorporating any additional materials. The resulting structure exhibits an aerogel-like morphology with an ultrahigh porosity of approximately 96 % and a low density of 0.05 g/cm 3 . Under ambient conditions with 65 % relative humidity, the AW-WWEG achieves a stable open-circuit voltage of 160 mV and demonstrates additional functionality as a sensing platform for detecting water content in kerosene. Specifically, it allows for effectively identifying water contamination in kerosene by tracking corresponding changes in voltage signals. Compared to untreated BW, the AW-WWEG exhibits a threefold enhancement in power generation efficiency while reducing the detection cost. This eco-friendly, self-powered device offers a cost-effective and sustainable approach for real-time monitoring of water contamination in kerosene.

Hexavalent chromium (Cr(VI)) contamination poses severe ecological risks due to its carcinogenicity and prevalence in industrial wastewater, where metal-organic frameworks (MOFs) show photocatalytic remediation potential. However, powdered MOFs suffer from poor recyclability and secondary pollution risks in practical applications. This study proposes an integrated structural-interfacial engineering strategy that combines the design of a robust three-dimensional fiber network framework with the interfacial engineering of MOFs and cellulose nanofibers to fabricate robust MOF-functionalized aerogel (MOFA) photocatalyst. The MOFAs feature hierarchical coordination effects enabling precise MOF crystallization control, achieving ultrahigh MOF loading (76.77 wt%), mechanical robustness (29 kPa stress at 70 % compression), exceptional stability (6.7 % permanent deformation after 100 cycles), and enhanced photocatalytic activity (photocurrent density of 2.87 μA/cm²). The optimized interfacial structure delivers superior adsorption (67 %) and photocatalytic performance (100 % Cr(VI) reduction in 80 min, > 94 % efficiency retention after 5 cycles), validated across diverse water matrices including high-salinity tanning wastewater under outdoor conditions. This innovative strategy offers a new design approach for developing high-performance photocatalytic materials and holds important application prospects in environmental governance.

Biomass flow fuel cells (BFFCs) are effective energy conversion technologies for converting biomass into electricity to realize a sustainable society. However, most of them depend on the thermal degradation of biomass, which is energy consumption and induces biomass polycondensation. Herein, we develop a novel solar-driven BFFC for converting lignin into electricity under sunlight at room temperature based on FeCl 3 /TiO 2 synergetic mediators, which endow a broad photo-absorption range and enhance absorption intensity for high photocatalytic activity. A new electron transfer chain is constructed by employing Fe 3+ to obtain electrons and efficiently promote electron-hole separation of TiO 2 . Meantime, the generated ·OH can depolymerize lignin rapidly. The BFFC achieved a power density of 64.4 mW/cm 2 at room temperature via sunlight irradiation with sodium lignosulfonate as fuel when paired with VO 2 + /VO 2+ catholyte. It can stably discharge and power LED light successfully. This work provides a sustainable and energy conservation approach for developing advanced biomass fuel cells.

Magnetic/fluorescent barcodes combine fluorescent dyes and magnetic materials in micrometer-sized host microspheres, offering high potential for high-throughput multiplexed biodetection automatically. However, the significant fluorescence quenching effect of magnetic nanoparticles (MNPs) towards organic luminogens limits the coding capacity in practical applications. In addition, aggregation-caused quenching (ACQ) and photon reabsorption effects of organic luminogens result in unpredictable fluorescence encoding numbers, and several experimental iterations are required. Herein, a reliable and simple strategy based on large stokes shift aggregation-induced emission (AIE) luminogens/magnetic barcodes is established for multiplex detection by eliminating the negative effects aboved of multicolor organic dyes. The in-situ generation and layer-by-layer modification strategies are utilized to prepare the related microspheres, which showed lower magnetic quenching effect and energy transfer process as expected. Thus, 36 encoded peaks are feasible based on the theoretical 6 × 6 barcode matrix with two colors and six intensity levels, providing great potential for large-scale multiplex detection. Based on the developed magnetic/fluorescent barcodes the excellent detection performance (detection limits: 5.5–20.6 pg·mL −1 ) are achieved for the detection of seven common cytokines from patient serum samples. These results indicate that the characteristic of AIEgens enjoying large stokes shift could give a barcode platform greater potential in the field of precision multiplex detection in clinic.

Background: Animal and cell studies have demonstrated that Zuogui-Jiangtang-Yishen decoction (ZGJTYS) has a favorable effect on the treatment of diabetic kidney disease (DKD). Our previous clinical research also showed that ZGJTYS prevents DKD in a manner similar to that of benazepril. Nevertheless, the interactions between ZGJTYS and the human gut microbiota require further investigation, particularly its interference in the intestinal flora response to food ingredients that may increase DKD risk, such as L-α-phosphatidylcholine and L-tyrosine.Objective: The aim of this study was to evaluate the regulatory function of ZGJTYS on human gut microbiota and explore the effect of ZGJTYS on the intestinal flora response to L-α-phosphatidylcholine and L-tyrosine.Methods: ZGJTYS was prescribed from the First Affiliated Hospital of Hunan University of Chinese Medicine. High-throughput sequencing of bacterial 16S RNA genes and fungal internal transcribed spacer (ITS) sequences was used for intestinal flora analysis. An in vitro gut microbiota simulation model was used to investigate the effect of ZGJTYS on the intestinal flora’s response to L-α-phosphatidylcholine and L-tyrosine. Ultra-high-performance liquid chromatography and mass spectrometry were used for non-targeted metabolomics analysis.Results: Compared to the control group, the microbial diversity of DKD was significantly reduced by ZGJTYS treatment; three bacterial genera, including Parabacterioids, were significantly higher; eight bacterial genera, including Prevotella_9, and the linoleic acid content were significantly lower. A receiver operating characteristic curve analysis using Parabacterioids and Prevotella_9 showed an area under the curve greater than 0.75, indicating good predictive performance. ZGJTYS intervention restored some of the normal bacterial genera, such as Rickettsia and Metarhizium, which were regulated by L-α-phosphatidylcholine and L-tyrosine. Furthermore, ZGJTYS effectively restored several significantly different Kyoto Encyclopedia of Genes and Genomes metabolic pathways related to immunity and disease to normal, such as efferocytosis and tryptophan metabolism.Conclusion: ZGJTYS was found to effectively restore the microbiota that were altered by L-α-phosphatidylcholine and L-tyrosine to normal, along with their metabolites. However, the mechanism by which ZGJTYS exerts its preventive and therapeutic effects on DKD through the gut microbiota still requires further study.

Ulcerative colitis (UC) is a prevalent inflammatory bowel disease (IBD) posing a significant health threat. This study explored the protective effects of D-tagatose against DSS-induced colitis in mice and its underlying mechanisms using H&E staining, AB-PAS staining, immunofluorescence, immunohistochemistry, ELISA, qPCR, western blotting, and other assays. D-Tagatose improved colitis by increasing body weight and colon length, with decreased DAI (disease activity index) and histopathological scores. The results showed that D-tagatose inhibited the secretion of myeloperoxidase (MPO), inflammatory enzymes (iNOS and COX-2) and pro-inflammatory cytokines (TNF-α, IL-1β and IL-6) as well as increased the content of anti-inflammatory cytokines (IL-10) in vitro. In addition, D-tagatose enhanced the expression of tight junction proteins (ZO-1 and Occludin) and mucin (MUC-2). Furthermore, D-tagatose was able to modulate the gut microbiota dysbiosis caused by DSS-induced UC and increased the content of short-chain fatty acids (SCFAs). This study indicated that D-tagatose attenuated DSS-induced UC by modulating inflammatory cytokines, restoring intestinal barrier function, maintaining gut microbiota homeostasis, and enhancing SCFA production. These findings provide D-tagatose as a safe and effective novel functional food strategy for the prevention and treatment of UC.

The remediation of toxic dye pollutants via covalent organic frameworks (COFs) presents a promising yet challenging strategy for sustainable water purification, as conventional powdered COFs face critical limitations in recyclability and secondary contamination risks. Herein, we introduce a paradigm-shifting approach combining template-assisted electrospinning with room-temperature dynamic covalent chemistry to fabricate hierarchically porous TAPT-TFPT COF hollow fibers, which address these bottlenecks. The synthesized fibers exhibit crystallographically ordered 2.2 nm pores, a high surface area (1402 m 2 g −1 ), and reliable chemical/thermal stability. These structural merits translate to unprecedented Congo red (CR) adsorption performance with a maximum capacity of 3670 mg g −1 (3–15 times higher than state-of-the-art COFs), size-selective removal efficiency, and comprehensive adsorption metrics including rapid kinetics (95 % removal in 6 h), pH adaptability (50–99 % efficiency across pH 2–12), and cyclic stability (90 % retention after 5 cycles). Mechanistic analyses reveal chemisorption-dominated Langmuir monolayer adsorption governed by pseudo-second-order kinetics, with molecular recognition driven by synergistic pore-size matching, multivalent hydrogen bonding, and π-π interactions. This work establishes an ambient aqueous synthesis platform for macroscopic COF architectures while redefining performance benchmarks for industrial-scale water treatment technologies.

A molecularly imprinted electrochemical sensor (MIECS) based on dual functional monomers was designed for the trace analysis of ramipril (RAM). The molecularly imprinted polymer (MIP) film was prepared by electropolymerization, p-aminobenzoic acid (p-ABA) and 2-amino-5-mercapto-1,3,4-thiadiazole (AMT) were used as dual functional monomers, and RAM was used as template molecule. Compared with sensors that only use a single functional monomer (p-ABA or AMT), the synergistic effect of dual functional monomers enhances the selectivity of MIECS. Under optimal conditions, the MIECS demonstrated a low detection limit of 23.9 fM within a wide linear range from 10 −13 M to 10 −6 M. Its application was validated by the successful detection of RAM in tablets with satisfactory recovery.

This study introduces an automated rotating cathode roller electrolysis system designed to eliminate cathode residue and ensure consistent production of high-quality dendritic copper powder (DCP). We systematically evaluated Cu, Mo, 316 L stainless steel (316 L), Ti, and Ta cathodes to unravel their impact on DCP morphology, residue accumulation, and energy efficiency. After 10 deposition cycles (10 min/cycle), Cu cathodes accumulated severe residue (89.62 g m −2 ), causing particle coarsening, a 51 % increase in apparent density, and 60 % higher energy consumption. The residue formation mechanism involves the initial deposition of a dense copper layer that bonds firmly to the Cu substrate, evolving into a residual layer after scraping. Ti initially showed low residue but degraded cyclically. Mo formed weakly adherent deposits that fragmented during scraping. In stark contrast, 316 L and Ta exhibited near-zero residue accumulation, consistently producing superior DCP with low apparent density (0.37–0.69 g cm −3 ) and fine particle size (10.02–29.82 μm). Surface characterization revealed that the presence of protective oxide layers on 316 L and Ta surfaces is key to inhibiting residue formation and corrosion. Ta emerged as the optimal cathode, achieving zero residue, exceptional corrosion resistance, stable high-quality DCP output, and minimal energy consumption during long-term operation.

Trichloroethene (TCE) and toluene are ubiquitous co-contaminants in groundwater and soil, yet effective strategies for their concurrent remediation remain challenging due to inhibitory interactions and substrate competition. In this study, we obtained two anaerobic enrichment cultures capable of detoxifying TCE and toluene with degradation rates of 141.7 ± 57.5 and 317.6 ± 1.3 µmol/(L·d), respectively. The 16S rRNA gene amplicon sequencing and quantitative PCR revealed that Dehalococcoides spp. dechlorinated TCE to ethene, while Azoarcus - Aromatoleum spp. mediated the toluene degradation under nitrate-reducing condition, with growth yields of 2.5 ± 1.3 × 10 8 copies/µmol Cl − released and 1.3 ± 0.2 × 10 9 copies/µmol toluene consumed, respectively. The enrichment cultures were successfully immobilized, maintaining degradation efficiencies comparable to those of free cells when individually exposed to respective contaminants. Under co-contamination scenario, complete TCE dechlorination was achieved only with immobilized cultures, as the immobilization matrix mitigated the toxicity from denitrification intermediates. When incorporated into sand columns to construct permeable reactive barriers (PRBs) simulating the groundwater flow system, the immobilized cultures completely degraded TCE and toluene (up to 547 μM) individually within 17 days. A hydrodynamically zoned bioremediation strategy was implemented for co-contamination removal, achieving 91.2% upstream TCE dechlorination and 78.98% downstream toluene oxidation. Elevated TCE loading (338 μM) without sufficient hydraulic retention time caused accumulation of dechlorination intermediates, whereas subsequent reduced TCE (169 μM) restored complete dechlorination to ethene. Toluene degradation remained suboptimal due to inhibitory effects from upstream TCE and its dechlorination intermediates. This study provides valuable technical insights and practical guidance for designing and implementing zoned bio-PRBs to address challenging groundwater co-contamination problems.
