In this study, a novel nitrogen-chlorine-codoped carbon quantum dots (NCl-CQDs) with low toxicity, thermal stability, good fluorescence properties, biocompatibility and high sensitivity was successfully prepared by hydrothermal carbonization. Based on the above advantages of NCl-CQDs, the NCl-CQDs was used to construct fluorescence sensing system for fluorescence probes. The maximum fluorescence emission wavelength was obtained at 470 nm when the excitation wavelength was 390 nm. The fluorescence signal was in the state of “ON”. The introduction of 2,6-Dichloroindophenol Sodium (DCIP) resulted in the quenching of fluorescence intensity due to photoinduced electron transfer between DCIP and NCl-CQDs. At this point, the color of the solution changed from brownish-yellow to light blue, indicating that the fluorescence signal was in an “OFF” state. Upon addition of ascorbic acid (AA) to the NCl-CQDs/DCIP system, the corresponding fluorescence signal was restored due to the special interaction between AA and DCIP. The color of the corresponding solution changed from light blue to colorless. The fluorescence signal was in the “on” state. Therefore, an “ON-OFF-ON” sensing system and colorimetric sensing system for AA was constructed using the NCl-CQD fluorescence probe. Under the optimized experimental conditions, the proposed methods exhibited satisfactory linear ranges. Specifically, the linear range for AA detection by the fluorescence sensor spanned from 1.2 μM to 180.33 μM, while that by the colorimetric sensor ranged from 1.32 μM to 166.55 μM. The corresponding detection limits were determined to be 0.68 μM and 0.55 μM, respectively. In summary, this sensing system could effectively enhance selectivity, sensitivity, and accuracy by preventing false positive detection results caused by environmental and system errors.

Industrial effluents containing persistent organic contaminants such as synthetic dyes and antibiotics are escalating global crises. Although membrane filtration offers an energy-efficient solution, its long-term performance is severely limited by fouling and the inherent permeability–selectivity dilemma. Herein, we propose a synergistic strategy to overcome these challenges by developing photocatalytic self-cleaning nanofiltration membranes through the incorporation of NiFe-MOF/CQD nanocomposites via interfacial polymerization. The introduced carbon quantum dots (CQDs) not only enhance the hydrophilicity and dispersibility of NiFe-MOFs but also markedly boost their visible-light photocatalytic activity. The optimized membranes (TFN-NC3) achieve an exceptional pure water permeance of 20.2 LMH/bar (L m −2 h −1 bar −1 )—approximately 2.3 times that of conventional thin-film composite (TFC) membranes—while maintaining a high Na 2 SO 4 rejection of 98.2% and outstanding removal rates (>86%) for multiple dyes across a range of molecular weights and charges. Moreover, the membranes demonstrate robust tetracycline rejection (>93.4%) over a broad pH range. Under visible-light irradiation, the TFN-NC3 membranes exhibit remarkable self-cleaning capability, sustaining a flux recovery rate above 95% over five consecutive filtration-regeneration cycles. This work provides a facile and scalable approach to fabricate high-performance, fouling-resistant nanofiltration membranes, offering a promising solution for the sustainable treatment and reuse of dye-laden wastewater.

The catalytic conversion of CO 2 into formic acid (FA) is a 100% atom economy strategy for carbon recycling, yet it remains challenging due to the need for high-performance catalysts. This study presents a well-defined single-atom Ru catalyst anchored on oxygen-deficient CeO 2 , synthesized via a facile solvothermal and calcination process followed by impregnation. The catalyst demonstrated exceptional efficiency for the selective hydrogenation of CO 2 to FA, achieving a remarkable turnover frequency (TOF) of 5719 h −1 . Experimental and characterization results revealed that oxygen vacancies (OVs) in CeO 2 significantly enhanced CO 2 adsorption and activation while stabilizing Ru species and increasing their charge density, thereby improving H 2 activation. The synergistic interaction between OVs and electronic metal-support interactions was identified as the key to the catalyst’s superior performance. This work provides valuable insights into the strategic design of heterogeneous catalysts, offering a pathway for efficient CO 2 utilization and broader applications in catalytic processes.

Reducing zinc content in epoxy zinc-rich coatings while maintaining corrosion protection remains challenging. Herein, we report a synergistic strategy using zinc gluconate-functionalized graphene oxide (ZnG-GO) to enhance the anticorrosion performance of epoxy low-zinc coatings (40 wt% Zn). ZnG-GO was synthesized via esterification with an optimal GO:ZnG ratio of 1:20, confirmed by FTIR and XPS. Grafted gluconate groups acted as electron donors and molecular spacers, increasing carrier concentration by 116% and mobility by 17%, thus enhancing coating conductivity by 86.3% versus unmodified GO. Electrochemical tests in 3.5 wt% NaCl solution showed that ZnG-GO coating maintained the highest low-frequency impedance (log|Z| = 6.367) and lowest corrosion current (1.803 × 10–8 A·cm-2) after 28 days. DSC analysis revealed 15.3% lower zinc consumption due to pH-responsive inhibition of grafted gluconate. Salt spray testing for 21 days confirmed no red rust propagation. This work provides an effective strategy for high-performance low-zinc coatings.

Decentralized, sustainable ammonia production could have an immense global impact. Here we describe an electrolytic approach to synthesizing ammonia directly from air and water under ambient conditions, which could be developed and optimized toward this goal. The system integrates a gliding arc discharge plasma reactor for generating \({\rm{NO}}_{\rm{x}}\) from air with a membrane electrode assembly reactor for the electrochemical reduction of \({\rm{NO}}_{\rm{x}}^{-}\) to ammonia, enhancing both the efficiency and scalability of the process. Furthermore, the plasma-generated \({\rm{NO}}_{\rm{x}}\) feedstock can be substituted with \({\rm{NO}}_{\rm{x}}\) derived from industrial waste, further extending the potential of this system. In this Protocol, we describe the fundamental principles of this plasma-electrochemical nitrogen reduction reaction (PE-N 2 RR) system and provide advice for experimental standardization, operational mechanisms and data analysis methods. The procedure starts with the synthesis of the catalyst—a La 1.5 Sr 0.5 Ni 0.5 Fe 0.5 O 4 perovskite oxide—at either laboratory or industrial scale. This catalyst is sufficiently stable to enable the \({\rm{NO}}_{\rm{x}}^{-}\) RR to continuously work under strongly acidic conditions. We highlight the key operating parameters that are necessary for plasma-based \({\rm{NO}}_{\rm{x}}\) production and electrochemical \({\rm{NO}}_{\rm{x}}^{-}\) reduction reaction systems. This information and framework can be used to optimize and streamline the entire PE-N 2 RR system. A moderate level of expertise in electrochemistry, plasma systems and catalyst synthesis is recommended to ensure successful execution. The setup of the entire PE-N 2 RR system, from catalyst synthesis to the configuration of plasma and electrochemical, is estimated to take 72 h. The full reaction operation test requires 200 h, whereas in situ electrochemical characterizations take 3 h.

Given the serious harm that microcystins (MCs) cause to public health and ecosystems (e.g., freshwater systems), there is a great need for an onsite MCs environmental assay that is cost-effective, easy-to-use, reliable and precise. Regarding this point, we here proposed a molecular imprinting-based selectively regulated laccase-like copper-doped carbon dot nanozyme (MIP@Cu-CD) to engineer a smartphone-assisted portable device, as a proof of concept, yielding the onsite visual colorimetric/fluorescence imaging-driven precise and reliable detection of MC-LR (a representative MCs) in real environmental waters. The detection mechanism was derived from the combination of MC-LR with its recognizable molecularly imprinted cavity, blocking the laccase-like activity-triggered MIP@Cu-CD to oxidize 2,4-dichlorophenol (2,4-DP) into a red quinoneimine product in the presence of 4-aminophenol (4-AP). At this moment, a decrease in colorimetric absorbance at 510 nm and a recovery of intrinsic blue fluorescence at 420 nm were observed in the MIP@Cu-CD + 2,4-DP + 4-AP system, with an increase in MC-LR concentration. On this basis, the system of MIP@Cu-CD + 2,4-DP + 4-AP was integrated with a home-made smartphone-assisted portable device to perform the onsite visual colorimetric/fluorescence images-based RGB detection of MC-LR in tap water, urban sewage, and lake water, with the detection limits of 0.227 μg/L and 0.101 μg/L in colorimetric and fluorescence ways, respectively. Moreover, the reliability was also confirmed by the liquid chromatography-mass spectrometry (LC-MS) method. This work provides a feasible approach to utilize molecular imprinting-based laccase-like nanozyme strategy to integrate portable devices for realizing the on-demand onsite detection of MCs in environmental waters.

Despite the promise of biomass-derived porous carbon for phase change energy storage, the simultaneously achieving high energy storage density, enhanced thermal conductivity, and efficient multi-modal energy conversion remains a challenge. To address this, we developed a composite of MXene and sorghum straw-derived biochar (MXene/SSBC) was synthesised, and tetradecylamine (TDA) was subsequently incorporated via vacuum impregnation to fabricate tetradecylamine/MXene/sorghum straw-derived biochar composite phase change materials (TDA/MXene/SSBC CPCMs). This work highlights the synergistic effect between the three components, enabled by the MXene/SSBC three-dimensional network effectively hosts TDA via capillary forces. The findings demonstrated that the specific surface area of the MXene/SSBC aerogel reached 247.3 m 2 /g. The latent heat of the TDA/MXene/SSBC CPCMs attained 220.2 J/g, a competitive value among reported biochar-based PCMs. After 50 thermal cycles, the composite retained 85.7% of its latent heat (188.7 J/g), demonstrating good cycling stability. Moreover, the thermal conductivity of TDA/MXene/SSBC CPCM-3 was measured at 0.408 W/(m·K), representing a 1.49-fold enhancement compared with pure TDA. The TDA/MXene/SSBC CPCMs displayed outstanding photothermal and electrothermal conversion efficiencies, reaching up to 95.6% and 87%, respectively.

To improve the flavor of tamarind and enhance its market prospects, Kluyveromyces marxianus was used to ferment tamarind pulp. The physicochemical properties, bioactive components, and flavor compounds of the tamarind pulp were determined. The mechanism underlying flavor formation in the fermented tamarind pulp was further explored from the perspectives of metabolomics and transcriptomics. During fermentation, the malic acid content increased significantly from 85.92 mg/100 mL to 546.76 mg/100 mL. Electronic nose analyses indicated a time-dependent enhancement of aroma complexity in fermented tamarind pulp. 3-Methyl-1-butanol, phenethyl alcohol, isoamyl acetate and phenethyl acetate were the dominated volatile compounds. The emergence of these flavor compounds markedly altered and enriched the aroma profile of tamarind pulp. However, the levels of flavor-contributing amino acids in the tamarind pulp decreased, though they were likely utilized by the yeast to generate new flavor compounds and support its growth. Transcriptome profiling revealed significant enrichment of pyruvate metabolism, amino acid degradation, and redox-related processes, providing molecular evidence for metabolic reprogramming in the yeast strain.

Solar-driven interfacial evaporation holds significant promise for mitigating global freshwater scarcity, yet its practical implementation is fundamentally limited by the suboptimal solar-to-thermal conversion efficiency of conventional materials, which suffer from narrow spectral absorption and uncontrolled thermal dissipation. Herein, for the first time, we propose an atomic-level symmetry-breaking design principle to address these challenges, as exemplified by tungsten trisulfide (W 2 S 3 ) with precisely engineered symmetry-broken lattices. The symmetry-broken W 2 S 3 architecture enables exceptional photothermal conversion and thermal localization by tailoring band-edge states to simultaneously enhance broadband light absorption and accelerate hot-carrier relaxation and recombination, while directional thermal rectification effectively regulates heat transport pathways to minimize parasitic energy losses. By incorporating W 2 S 3 into a 3D porous hydrogel evaporator, an extremely high evaporation rate of 7.862 kg m −2 h −1 is achieved, along with a competitive solar steam efficiency of 92.2%, approaching the theoretical thermodynamic efficiency limit of 92.5% under 1 sun illumination. This work establishes a transformative framework for designing advanced photothermal materials and propelling the development of next-generation solar-driven desalination technologies.

Mechanochemistry is an efficient, solvent-reduced, and extra heat-free green chemistry method. In this work, mechanochemistry is applied to the polymerization of PLA. The resulting PLA was esterified with citric acid to obtain a vitrimer-like polymer, which was also carried out via mechanochemistry. These mechanochemistry processes were performed using a planetary ball mill, which is favorable for scale-up synthesis. The synthesized polymer was characterized by NMR and SEC, and the vitrimer-like properties were evaluated by rheology, DSC, TGA, and shape memory behavior. Graphical Using mechanochemistry, PLA is polymerized via an efficient, solvent-reduced, heat-free route. The as-synthesized PLA is then further converted into a vitrimer-like polymer by mechanochemical modification. The resulting material exhibits dynamic network behavior, as confirmed by thermal, rheological, and shape-memory analyses.

β-Glucosidase (BGL) is limited by the catalytic efficiency and environmental tolerance in the biomass biorefinery process. In this study, maleimide and its derivatives were used to modify BGL. FT-IR, circular dichroism, ζ-potential, ultraviolet, and fluorescence were used to characterize the conformational alteration of the thiol-modified enzyme and induced the enhancement of rigidity and substrate affinity. Molecular docking revealed that the modified BGL, especially Moc-Mal-BGL, had lower binding energy (−6.8 kcal mol–1) and shorter average hydrogen bond length (2.018 Å) with the substrate. The activity of Moc-Mal-BGL increased by 110.6% compared with native BGL and realized a 2.6-fold increase in catalytic efficiency kcat/Km (13.92 s–1/mM). The corresponding cellobiose conversion rate increased by 19.0%. Thermal stability, storage stability, solvent (GVL and DMSO) tolerance, and glucose tolerance of Moc-Mal-BGL were significantly improved. This work provides a rapid strategy to improve the catalytic efficiency and environmental tolerance of BGL and investigates the mechanism in depth.

Bismuth vanadate (BiVO 4 ), a widely employed functional material in pigments and photocatalysts, is susceptible to environmental release during manufacturing and application. Previous researches showed that the dissolution of BiVO 4 could be induced by light irradiation, releasing Bi(III) and V(V) ions. Besides, Bi(III) can be converted into volatile and toxic species under UV irradiation in the presence of low molecular weight organic acids (LMWOAs). However, the influence of LMWOAs on the photodissolution of BiVO 4 and the subsequent transformation of the dissolved Bi(III) remains unclear. In this study, it was found that under UV irradiation, BiVO 4 was dissolved and then further transformed into volatile Bi in media such as formic acid (FA), acetic acid (AA), oxalic acid (OA), and citric acid (CA). The generation efficiency of volatile Bi was enhanced by the co-existing Cl − ions through the consumption of hydroxyl radicals (•OH). The recombination of electron-hole pairs on the surface of BiVO 4 could be inhibited by LMWOAs acting as electron donors, and the dissolution was thereby promoted. In addition, the dissolved Bi(III) could be converted into volatile substances by the radicals generated from the photolysis of LMWOAs. (CH 3 ) 3 Bi was speculated to be formed from BiVO 4 in the AA medium, while BiH 3 was released in the FA, OA, and CA media. Transmission electron microscopy characterization showed a lightening of the color of the edges of BiVO 4 particles after light exposure, confirming the dissolution of BiVO 4 . The research results provide a scientific basis for evaluating the environmental migration and transformation risks of BiVO 4 .
