The present work constructs a novel Ag₂S/CN composite photocatalyst via in-situ hydrothermal method. The photocatalytic performance of the obtained Ag₂S/CN composite was meticulously evaluated through the degradation of methyl orange (MO) under visible light irradiation. Compared to pure CN and Ag₂S, the Ag₂S/CN composite exhibited significantly enhanced photocatalytic performance. Specifically, the optimal Ag₂S/CN (0.4) sample achieved activities that were 70 and 5 times higher than those of Ag₂S and CN, respectively. This remarkable enhancement can be attributed to the reduced band gap and expanded light absorption range of CN when combined with Ag₂S. Additionally, the surface plasmon resonance (SPR) effect of Ag 0 nanoparticles generated during photodegradation further improves photocatalytic performance by facilitating the separation of photogenerated carriers. Based on photoelectrochemical properties and active species trapping experiments, a plausible mechanism involving hydroxyl radicals (·OH) and superoxide radicals (·O₂⁻) is proposed. The combination of wide-bandgap and narrow-bandgap semiconductors offers a promising strategy for developing efficient photocatalysts for wastewater treatment.

The pulp and paper industry faces growing challenges arising from fiber shortages and environmental concerns. High yield pulping technology has emerged as a key solution, but the high lignin content in high yield pulp (HYP) restricts its brightness, posing a significant challenge for the bleaching process. Although traditional strong alkaline hydrogen peroxide (H 2 O 2 ) bleaching of HYP is effective, it results in fiber yield loss and the generation of anionic impurities, thereby bringing about additional environmental burdens. In contrast, weakly alkaline H 2 O 2 bleaching is more environmentally friendly and preserves a high pulp yield, but it struggles to achieve the desired brightness due to the reduced reactivity of lignin. This work addresses these challenges by investigating the effect of xylanase-pectinase (XP) pretreatment combined with weakly alkaline H 2 O 2 bleaching to improve both bleaching efficiency and environmental benefits in the bleaching of poplar chemi-thermomechanical pulp (CTMP). The kinetic analysis reveals that the XP pretreatment significantly enhanced the efficiency of weakly alkaline H 2 O 2 bleaching, accelerating lignin removal and increasing pulp brightness. The XP pretreatment effectively reduced the electrical conductivity, cationic demand, and chemical oxygen demand of the bleaching effluent. The mechanism studies demonstrate that the XP pretreatment effectively cleaved lignin-carbohydrate complex linkages and degraded hemicelluloses side chains, significantly increasing the accessibility and reactivity of the residual lignin. The integration of XP pretreatment with weakly alkaline H 2 O 2 bleaching can offer a sustainable and efficient process for poplar CTMP upgrading, simultaneously enhancing the bleaching efficiency and mitigating the environmental footprint.

Agricultural crop yields are limited by soil nutrient status and crop nutrient utilization efficiency. Both intercropping and arbuscular mycorrhizal fungal colonization can increase plant nutrient utilization and crop yields. However, although common mycorrhizal networks have been widely studied, the role of arbuscular mycorrhizal fungi in mediating nutrient transfer within networks formed between intercropped plants, and the consequences for the component crops, remain insufficiently resolved. We hypothesized that CMN-mediated P redistribution between intercropped maize ( Zea mays L.) and soybean ( Glycine max (L.) Merr.) is governed by plant P demand (sink strength), and that the direction and magnitude of P transfer shift under contrasting soil P supply. Here, we combined a five-chamber root device with multi-wavelength quantum-dot P labeling to directly trace CMN-mediated P transfer in a maize–soybean intercropping system. A maize–soybean intercropping system was established in a greenhouse under two phosphorus supply levels (low P, 20 mg kg⁻¹ Olsen-P; high P, 100 mg kg⁻¹ Olsen-P) to investigate P allocation within plant–mycorrhiza associations and mycorrhizal networks. Plant physiological traits (photosynthetic parameters and biomass), root traits, and rhizosphere enzyme activities were simultaneously quantified to link CMN-mediated P transfer with plant performance and soil P cycling. In low-phosphorus conditions, inoculation with Diversispora epigaea significantly improved maize physiological in-dices but had no significant effect on soybean, and facilitated net phosphorus (P) transfer from soybean to maize through the common mycorrhizal network (CMN). Under high-phosphorus conditions, inoculation markedly enhanced soybean physiological indices, inhibited maize growth, and redirected P transfer from maize to soybean via the CMN. Overall, mycorrhizal inoculation increased the total P flux within the maize–soybean intercropping system, and the direction of inter-plant P exchange was regulated by the fungal mycelial network in response to contrasting soil P supply, which altered host P demand.

SiZnOC gels were coated on C/C substrate by sol–gel, using methyltriethoxysilane (CH 3 Si(OCH 2 CH 3 ) 3 , MTES) and dimethyldiethoxysilane ((CH 3 ) 2 Si(OCH 2 CH 3 ) 2 , DMDES) as precursors, and zinc acetylacetonate (Zn(acac) 2 ) as the modifier. After pyrolysis under argon at 700 °C, SiZnOC ceramics were obtained. Microstructures of SiZnOC with different Zn/Si molar ratios were characterized by FTIR, XRD, SEM and XPS. Biocompatibilities of SiZnOC ceramics were measured by MTT, cell adhesion, antimicrobial activity of Escherichia coli and Staphylococcus aureus, DPPH free radical scavenging and reactive oxygen species (ROS) levels. Vitro bioactivities of materials were evaluated by the generation of bone-like hydroxyapatite (HA) in simulated body fluid (SBF). Results showed that antibacterial and antioxidant properties of SiZnOC enhanced with the content of Zn doping. When Zn:Si molar ratio of SiZnOC increased to 0.4, the inhibition zone diameters were the biggest of 6.7 mm and 5.4 mm for E. coli and S. aureus, respectively, and the scavenging rate was the highest of 88.9% for the DPPH free radicals. However, the level of intracellular reactive oxygen species (ROS) expression was promoted with the increase of Zn doping either. SiOC with Zn:Si molar ratio of 0.2 has the quickest speed of generation bone-like hydroxyapatite (HA) in SBF, on the balance of biocompatibility, bioactivity and antimicrobial performance, SiZnOC with Zn:Si molar ratio of 0.2 was the best for the moderate antimicrobial and antioxidant properties, and the qualified biocompatibility.

Bamboo is a naturally-optimized composite material, but it is prone to deformation, cracking, mildew, and decay. The application of coatings with both mildew and decay resistance can provide long-term protection for bamboo, but bamboo lacks transverse cells and contains few fiber cell cavities and pits, leading to poor coating adhesion. This study subjected Phyllostachys edulis ( P. edulis ) and Neosinocalamus affinis ( N. affinis ) substrates to hygrothermal pretreatment to enhance the adhesion of coatings applied to them. A novel nano-Ag/SiO 2 -modified water-based coating with excellent dispersibility and thermal stability was applied to the surface of the pretreated bamboo strip substrates. The adhesion of the coating reached the highest level (Grade 0, no coating detachment), and its initial and maximum peel forces increased by 53.8% and 41.1% after hygrothermal pretreatment, respectively. Upon increasing the nano-Ag/SiO₂ content, the thickness, adhesion, hardness, scratch resistance, resistance to heating-cooling cycles, and mildew/decay resistance of the water-based coating improved. After the mildew resistance tests, the infection level of the samples decreased from Grade 3 (1/2–3/4 of the surface) to Grade 0 (No visible hyphae), while the discoloration level decreased from Grade 4 (severe surface and internal discoloration) to Grade 1 (minor surface discoloration) after soil burial tests. The weight loss rate, gloss reduction, and color difference of the surface also decreased after both tests. The results showed that the water-based coating modified with 2 wt% nano-Ag/SiO 2 exhibited the best dispersion uniformity, abrasion resistance, and minimal color difference, providing the best decorative and protective performance for the bamboo. The coating extended the service life of bamboo and enhanced its applicability in high-humidity indoor environments and harsh outdoor conditions.

Electrochemical chlorine evolution is a promising approach for antimicrobial and wastewater treatment. However, the large-scale applications of conventional electrodes are hindered by the high cost of precious metals and tedious thermal decomposition method. In this study, precious metal-free electrodes for chlorine evolution were fabricated via liquid plasma spraying technique using a Ti 0.35 V 0.35 Sn 0.25 Sb 0.05 feedstock solution with varying total metal concentration. Scanning electron microscopy combined with EDS elemental analysis showed that the coatings exhibited a loose and porous morphology, with Ti, V, Sn and Sb elements uniformly distributed throughout. X-ray diffraction analysis identified characteristic diffraction peaks corresponding to VO 2 , SnO 2 , Sb 2 O 5 and TiO 2 in the coatings. The electrocatalytic properties of the coatings were evaluated using multiple electrochemical techniques, and the electrode prepared using the 1.0 M feedstock solution demonstrated the best performance. Antimicrobial test showed that after 30-s electrolysis, the disinfection rates of simulated tap water against E. coli and S. aureus exceeded 88.1% and 96.8%, respectively, whereas for the 0.06 M NaCl solution, both pathogens were inactivated by over 99.9% within 15 s. Additionally, methylene blue degradation reached 98.4% after 45 min of electrolysis. This study provides a new strategy for producing low-cost chlorine-evolving electrodes with potential application in antibacterial and wastewater treatment.

The treatment of industrial wastewater containing multiple heavy metals (MHMs) remains challenging, primarily because conventional adsorbents suffer from poor stability, limited adsorption capacity in mixed-metal systems, or high energy consumption during synthesis. To address these issues, this study employed a room-temperature in-situ impregnation method to load NH 2 -MIL-100(Fe) onto amine-functionalized magnetic hydrochar (HBAP). Three highly dispersible magnetic composites, designated as NM-100-HBAP-X (X = 0.75, 1, 1.25), were synthesized by adjusting the mass ratio of NH 2 -MIL-100(Fe) to HBAP. Experimental results demonstrated that the optimal material (NM-100-HBAP-1) exhibited high adsorption capacities for Pb(II), Cd(II), and Cr(VI) in a mixed-metal system. The maximum adsorption capacities determined by the Langmuir model were 181.13, 175.02, and 158.69 mg/g for Pb(II), Cd(II), and Cr(VI), respectively, which are comparable to previously reported values for hydrochars or MOF-based materials. Mechanistic analysis revealed that amino groups facilitate a synergistic process by reducing Cr(VI) to Cr(III), which is then immobilized via complexation and co-precipitation, thereby further enhancing Cd(II) removal. The material also demonstrated good cycling stability, retaining over 50% of its initial adsorption capacity after five regeneration cycles, and maintained effective performance in various real water samples. Furthermore, toxicity tests confirmed its environmental safety, and life cycle assessment quantified the GWP of producing 1 kg of NM-100-HBAP-1 as 41.224 kg CO 2 eq, with electricity and NH 2 -H 2 BDC synthesis as the dominant contributors. This study not only provides an efficient adsorbent for heavy metal removal but also offers a systematic research framework integrating material design, mechanistic investigation, and environmental assessment for pollution remediation.

A dual-site functional orchestration strategy is proposed using 2-imidazolidone to simultaneously reconfigure the anodic solvation structure and suppress the cathodic polyiodide shuttle.
The carbonyl (C=O) group modulates Zn 2+ solvation to induce preferred (002) deposition, while the imino (N-H) group chemically moors polyiodides via hydrogen bonding, achieving decoupled synergistic regulation.
This molecular engineering enables a record-breaking lifespan exceeding 5500 h at 8 mA cm -2 for Zn anodes and durable full-cell cycling with 79.4% capacity retention over 2500 cycles.

Extracellular vesicles (EVs) have emerged as promising vehicles for drug delivery and disease therapy owing to their intrinsic biocompatibility and capacity to transfer functional biomolecules. However, limitations in current storage technologies, including structural degradation and bioactivity loss during long-term freezing, and the incompatibility of conventional cryoprotectants such as DMSO and glycerol with intravenous administration, pose major barriers to clinical translation. Herein, we developed DDAS, a biomimetic cryoprotectant formulation, rationally designed through generative artificial intelligence (GAI)-assisted prioritization of physiologically relevant candidates from the Human Metabolome Database . DDAS comprises dextran, albumin, and sialic acid, which were selected for their synergistic stabilization and inherent biocompatibility. Compared with standard preservation media, DDAS markedly improved EVs stability during prolonged cryopreservation and repeated freeze-thaw cycles, effectively preserving vesicle morphology, particle concentration, and cargo protein functionality while reducing aggregation and membrane damage. Notably, DDAS exhibited negligible cytotoxicity and excellent biocompatibility, enabling direct intravenous administration without re-isolation or washing. Importantly, stem cell-derived EVs preserved in DDAS fully retained their therapeutic activity in vivo, significantly attenuating inflammation and accelerating wound repair upon systemic administration. Together, this study develops and validates DDAS, a practical, clinically feasible biomimetic cryoprotectant assisted by GAI. DDAS enables the long‑term preservation of EVs with intact functionality and significantly enhances the therapeutic efficacy of stem cell EVs in wound healing, ultimately unlocking their full clinical potential.

Under extremely sub-zero conditions, intelligent acoustic devices suffer from poor reliability due to ice accretion that obstructs acoustic pathways, while most existing fibrous protective membranes still face trade-offs between anti-icing robustness and acoustic transparency. Herein, inspired by the hierarchical architecture of Papilio paris wings, we present an eco-friendly electro-ridge-netting strategy that enables facile fabrication of biomimetic dual-scale nanofiber-nanowire network (Bio-net) acoustic membranes through coupled electrohydrodynamic jet evolution and phase separation. This strategy creates ridge-like scaffold nanofibers seamlessly integrated with two-dimensional (2D) Voronoi nanonetworks composed of deep-subwavelength nanowires (∼14 nm), yielding fluorine-free superhydrophobic membranes with nanoscale pores (∼336 nm) for efficient water resistance. The Bio-net membranes exhibit prolonged icing delay of 593.2 s and low ice adhesion strength of 15.3 kPa, effectively suppressing ice accretion under extreme cold conditions. Simultaneously, their breathable porous architecture and ultra-low airflow resistivity minimize acoustic impedance mismatch, yielding exceptional acoustic transparency with transmission loss below 1.78 dB across 63–6300 Hz. When deployed in acoustic electronic systems, the membranes provide durable, high-fidelity acoustic protection at −20 °C. This study reconciles anti-icing robustness with broadband acoustic transparency, establishing a bioinspired design paradigm for next-generation fibrous acoustic protective membranes in extreme environments.

Concentrated solar power (CSP) has emerged as a potential desalination technology from the renewable energy barrel. Unlike the old-fashioned ways that consume a huge amount of fossil fuel, CSP is a sustainable and environmentally friendly alternative. CSP-based desalination systems that employ multi effect distillation, multistage flash and reverse osmosis technologies use the sun's energy to produce potable water from saline sources. This paper gives an overview of the latest developments in CSP-based desalination technologies. It discusses performance, identifies problems and addresses the combination of these systems with various desalination processes. Although there are many studies concerning single CSP systems, many issues of a systematic comparison of different systems and a hybrid integration of different renewable energy technologies as well as long-term sustainability under different environmental conditions are still undiscovered. Additionally, high initial costs and inefficiencies from scaling and environmental factors are major obstacles to widespread adoption. The review brings out key technological, economic and environmental challenges. It provides significant information for the improvement needs in the CSP desalination systems. Novel strategies are introduced, such as the hybrid systems with combination of CSP and other renewable sources, the use of advanced materials to increase efficiency, and optimization of operational parameters. The results highlight the need for further studies of cost reduction techniques, system optimization and large-scale implementation. In conclusion, this paper shows the importance of the CSP-based desalination in solving the water shortage problem in the world. It describes a roadmap for future developments in this field.

Host defense peptides (HDPs) possess both direct bacteriocidal and immunomodulatory activities. In this study, chicken cathelicidin-1 (cCATH-1) and chicken cathelicidin-3 (cCATH-3) were selected based on their markedly different minimum inhibitory concentrations (MICs) against avian pathogenic Escherichia coli (APEC) strains, with MICs of cCATH-1 being 4- to 16-fold lower than those of cCATH-3. However, following intraperitoneal challenge with APEC strain E058 (4 × 10⁶ CFU/mouse), 80% of cCATH-3 treated mice survived while 20% of cCATH-1 treated mice survived. Flow cytometry (FC) revealed significantly lower peripheral blood Ly6C high monocytes but higher peritoneal Ly6C high macrophages in cCATH-3-treated mice at 4 and 8 h post-treatment. Peritoneal CCL3 secretion was significantly upregulated in cCATH-3 treated mice at 8 h post-treatment. Upon knockout of macrophages, the protection of cCATH-3 in mice against APEC E058 challenge was markedly abolished. In vitro, peritoneal macrophages treated with cCATH-3 showed stronger bacteriocidal activity than those treated with cCATH-1. Mouse CCL-3 (mCCL3)-specific antibody neutralize the effect of mCCL3 on macrophages chemotaxis in vitro. mCCL3-specific antibody administration resulted in 0% survival in cCATH-3-treated mice versus 60% survival in cCATH-3-treated mice administered with mock antibody, while cCATH-1-treated mice showed 0% survival administered with either mCCL3-specific antibody or mock antibody after APEC E058 strain challenge. In summary, cCATH-3 provides robust protection against APEC infection compared with cCATH-1 in mice, partially through CCL3-mediated macrophage chemotaxis and enhanced bacteriocidal activity in activated macrophages, revealing a novel mechanism of avian cathelicidins and supporting HDPs as alternatives to antibiotics for controlling avian colibacillosis.
