Magnaporthe oryzae causes a fungal disease that poses a serious risk to global food security. Nanoagrochemicals are perceived as sustainable, economical, and environmentally friendly alternatives to traditional pesticides. Plant immune activators can be applied as the active ingredients of nanopesticides to control diseases in agriculture, but their use is limited and corresponding research is lacking. In this study, a nanodelivery system (PBZ@CaCO3@SG) for the on-demand release of a plant immune activator (probenazole; PBZ) was prepared using nano-CaCO3 after coating with sodium alginate–gelatin (SG). In vitro, at 48 h, the release rate reached 97.9% and 88.4% at pH 4.5 and 6.0, respectively, which greatly exceeded that under neutral conditions (pH 7.4), with acid-responsive release characteristics. Moreover, it responded quickly to the acidic microenvironment generated during M. oryzae infestation and rationally released PBZ, effectively improving plant resistance to M. oryzae and minimizing disease. Notably, M. oryzae infection was markedly reduced, by 60.6%, after PBZ@CaCO3@SG treatment. Mechanistically, PBZ@CaCO3@SG enhanced both physical barrier formation and systemic acquired resistance in rice, enhancing resistance to M. oryzae. It also showed good biosafety for both microbial communities and earthworms in the soil. This comprehensive study revealed multiple mechanisms by which PBZ@CaCO3@SG interacts with plants and pathogens, inhibits damage, and maintains nontarget biosafety, emphasizing its great potential for plant disease management.

The composite biopolymer hydrogel beads (G-SA-cCNF) based on gelatin (G)/sodium alginate (SA)/carboxylated cellulose nanofibrils (cCNF) were prepared by a dual-cross-linking method using transglutaminase (TG) and calcium chloride (CaCl2) as cross-linking agents. Effects of TG cross-linking time on the structure, swelling response, and controlled-release behaviors of hydrogel beads were mainly evaluated. TG cross-linking improved the sphericity, water-holding capacity, texture, mechanical properties, and thermal stability of hydrogel beads. The hydrogel beads exhibited remarkable pH/ion-responsive characteristics. In simulated gastric fluid, the diameter decreased that can provide protection for active substances, while in simulated intestinal fluid, the diameter increased that can facilitate the controlled release of active substances. TG cross-linking can endow the hydrogel beads with a denser internal network structure, effectively controlling the release of bioactive substances such as bovine serum albumin (BSA). Overall, TG cross-linking improved the properties of the hydrogel beads and enabled precise regulation of release.

From the perspectives of environmental protection and sustainable development, gold recycling is of paramount importance. This study presents a green synthesis of imine-based porous organic polymers (POPs) using an ionic liquid as the reaction medium. The imine groups within the POPs can be protonated under acidic conditions, transforming them into pH-responsive ionic POPs. Through a synergistic mechanism of electrostatic interaction and in situ reduction, the proposed POP demonstrates an exceptional gold adsorption capacity of 1299.6 mg g⁻ 1 , achieves rapid equilibrium within 15 min, exhibits high selectivity, and maintains excellent reusability over ten consecutive cycles. The adsorption process followed pseudo-second-order kinetic model and the Freundlich isotherm, while thermodynamic analysis confirmed its chemisorption nature. This work not only provides a novel strategy for fabricating ionic POPs but also demonstrates their significant potential for efficient gold recovery from electronic waste.

The development of efficient and stable oxygen reduction reaction (ORR) catalysts is critical for advancing sustainable energy technologies, particularly rechargeable zinc-air batteries (ZABs) which offer high theoretical energy density, inherent safety, and cost-effectiveness compared to other metal-air systems. However, the widespread application of ZABs is hindered by the sluggish kinetics of the air cathode ORR, and state-of-the-art Pt-based catalysts suffer from high cost, susceptibility to poisoning, and inadequate durability in neutral media. To address this challenge, non-precious metal catalysts represented by metal‑nitrogen‑carbon dopants have attracted significant attention due to their geometrically constrained coordination environments that resist hydrolytic dissociation and electronic structures capable of circumventing specific adsorption poisoning pathways. Herein, we report a molecularly engineered manganese single-atom catalyst (MnNC-0.5) synthesized via a cyano-amino coordination strategy coupled with MgO-templated pyrolysis. This approach creates well-defined Mn N 4 sites adjacent to -CN functional groups within a hierarchical porous carbon matrix. The catalyst exhibits exceptional ORR activity across the entire pH spectrum, with half-wave potentials of 0.89 V in 0.1 M KOH, 0.77 V in 0.5 M H 2 SO 4 , and 0.69 V in 0.1 M PBS. It also demonstrates remarkable stability, retaining over 90% of its initial current after 35,000 s of continuous operation. Density functional theory (DFT) calculations reveal that the adjacent -CN group electronically modulates the Mn N 4 center, optimizing the adsorption free energy of oxygen intermediates and thereby enhancing the intrinsic activity. When employed as an air cathode in a liquid ZAB, the MnNC-0.5-based device achieves a peak power density of 193.4 mW cm −2 and a high specific energy density of 1094 Wh kg Zn −1 , outperforming the Pt/C benchmark. This work provides a viable molecular-engineering strategy for designing high-performance, pH-universal ORR electrocatalysts for next-generation energy conversion and storage devices.

Wheat gluten (WG) is an abundant but underutilized plant protein, with its application limited by poor solubility and allergenic potential. This study developed an integrated biorefinery approach combining pH-shifting pretreatment (acidic, pH 2→7; alkaline, pH 12→7) with fermentation using Pediococcus acidilactici XZ31 . Alkaline pretreatment proved most effective in dismantling the disulfide-bonded network and inducing a molten globule-like state, significantly enhancing protein solubility and surface hydrophobicity. This structural modification markedly improved substrate accessibility during fermentation, accelerating proteolysis kinetics (peak peptide accumulation at 8 h vs. 20 h in the control). Proteomic analysis revealed more extensive hydrolysis of proline-rich gliadins and glutenins in the alkaline-pretreated group. This hydrolysis yielded a greater diversity of bioactive peptides—including those with drug-delivery, ACE-inhibitory, and antihypertensive properties—and enhanced ACE inhibitory activity. Critically, it also achieved a superior reduction in immunogenic epitopes and IgE-binding activity. This work establishes a scalable, green processing strategy that enhances the functionality and safety of wheat gluten (WG), facilitating its valorization into high-value food ingredients.

The amphiphilic balance between cationic and hydrophobic segments is a critical determinant of the trade-off between antibacterial activity and biocompatibility of membranolytic polymers. In tertiary amine-based systems, this balance is dynamic and exquisitely sensitive to the pH of the tissue microenvironment. To elucidate the relationship between polymer composition and antibacterial efficacy across a physiological pH range, we developed a library of polymeric proton-gated membranolytic switches (PPGMSs) composed of butyl methacrylate and various tertiary amines. These switches achieve precise, pH-activated antibacterial activity, which is governed by the equilibrium between cationic (protonated amine) and hydrophobic butyl methacrylate and deprotonated amine domains. The switching pH of these switches increases with a higher proportion of tertiary amine or a decrease in higher amine hydrophobicity. From this library, P(E 60 /B) emerged as a lead compound, demonstrating potent activity against E. coli and P. aeruginosa under acidic conditions, and minimal cytotoxicity toward mammalian cells at neutral pH (7.4). Mechanistic studies confirmed bacterial membrane disruption as the mode of action. Crucially, P(E 60 /B) exhibited significant efficacy in a murine peritonitis model, reducing bacterial loads in a dose-dependent manner. This work establishes PPGMSs as a versatile platform for designing precision antimicrobials that leverage microenvironmental cues for selective therapy.

Metal-phenolic networks (MPNs) are widely used to improve the structure, mechanical properties and stability of gels. In this study, tannic acid (TA) was coordinated with metal ions (Mn 2+ and Zn 2+ ) under pH conditions of 2.0, 5.5, and 8.0 to form MPNs, which subsequently induced soy protein hydrolysate nanofibrils (SPHN) to produce gels (SPHN-MPNs gels). As the pH increased, the coordination interactions between TA and Mn 2+ /Zn 2+ became progressively stronger, as reflected by the emergence of new charge-transfer–related absorption features. Spectral analysis confirmed that MPNs could promote gel cross-linking via hydrogen bonds and metal ions coordination interactions between MPNs and SPHN. Gels induced by MPNs displayed a denser gel structure as the pH increased, resulting in higher storage modulus and elevated thermal transition temperature. MPNs formed between TA and Zn 2+ at pH 8.0 imparted higher G′ values and a faster recovery rate to the gels after four shear-stress cycles. These findings will expand the potential applications of SPHN-MPNs gels in the food industry.

This work presents the design of UiO-66-PDA@TANI, a novel MOF-oligomer nanocomposite that synergistically integrates pH-triggered inhibitor release with redox-mediated passivation to enhance epoxy coating protection. Release studies revealed a 13-fold increase in alkaline-activated Zr 4+ /ligand release, while cyclic voltammetry and electron paramagnetic resonance analyses confirmed that heterogenous integration of UiO-66 improves the electron transfer efficiency of TANI. Potentiodynamic polarization tests demonstrated that UiO-66-PDA@TANI achieved a corrosion inhibition efficiency of 75.62% in saline solution within 24 h. Long-term EIS measurements showed superior barrier properties, with the composite epoxy coating exhibiting |Z| 0.01Hz = 1.85 × 10 10 Ω·cm 2 after 60 d of immersion, compared to 5.51 × 10 7 Ω·cm 2 for pure epoxy. Artificial defect experiments further revealed self-healing behavior, with an improvement efficiency of 229.67% after 48 h, indicating localized protection beyond that of pristine coatings. These findings demonstrate that the synergistic interplay between UiO-66 and TANI enables dual protection: rapid inhibitor delivery at corrosion sites via pH-induced framework disintegration and regeneration of passivation films via enhanced TANI redox cycling for long-term durability. This work introduces a previously unreported strategy that leverages UiO-66 for electron conduction-enhanced corrosion protection, offering fundamental design principles for pH/redox dual-responsive protective systems.

External temperature and pH variations inevitably affect the measurement accuracy of the enzymatic biosensors. In order to solve this problem, a glucose biosensor with temperature and pH compensation was proposed and experimentally demonstrated. The biosensor is composed of a segment of hole-assisted three-core fiber (HATCF) and a segment of hole-assisted dual-core fiber (HADCF) in series and achieve three-parameter detection of glucose concentration, temperature and pH based on mode resonance coupling. One suspended core of the HATCF is functionalized with graphene oxide (GO)/glucose oxidase (GOD) for glucose concentration detection, and the other suspended core is utilized for temperature monitoring. The HADCF filled with polyacrylamide hydrogel is used to monitor pH change. This biosensor exhibits a linear response with a sensitivity of 6.82 nm/(mg/mL) under optimal reaction condition (T = 35 °C, pH = 7.0), enabling simultaneous glucose detection and monitoring of the reaction environment temperature and pH. The advantages of stable response, high selectivity, compact size, and three-parameter simultaneous detection make the proposed biosensor a significant candidate for its applications in multi-parameter sensing, environmental biomonitoring and real-time interference compensation detection.

Aiming to improve the low stability of blueberry anthocyanins (BA) and moisture absorption of the ethylene vinyl alcohol copolymer (EVOH), BA was encapsulated in EVOH and then dispersed in PVA solution to form water in water (W/W) emulsion, and further electrospun into nanofibers. The stability of the emulsion was analyzed by bio microscopy and zeta potential particle size analyzer. The successful encapsulation of BA/EVOH in the continuous phase of PVA was verified by infrared spectroscopy. The incorporation of BA significantly improved the oxidation resistance and UV resistance of the membranes, which could completely block UVB region and most of the UVA region. In addition, water vapor transmission rate and mechanical properties were effectively enhanced after thermal crosslinking. Finally, the potential application of the membrane in shrimp spoilage monitoring was explored, where the color of the indicator changed from mauve to grayish blue during indoor sealed storage. The results suggest that the membrane can monitor shrimp spoilage in real time through pH changes and the developed index membrane would be a good candidate as intelligent food package material.

The selectivity factor α (2.636) and the relative selectivity factor β (2.468) indicated MMIPs had good specific recognition ability for silybin. In addition, a series of experimental data displayed MMIPs had many other excellent characteristics such as adsorption property, swelling performance, biocompatibility , degradability , stability, reproducibility and so on. The cumulative release rates of MMIPs could reach 29%, 23% and 25% in the media of pH 1.0, 7.4 and 8.2 at 37.5 °C, resepectively, and when the temperature was raised to 43 °C, the release rate of MMIPs in solution (pH 7.4) reached 49%, which indicated that the carrier material had good pH/temperature dual responses.

In this study, a bimetallic Cu 0 /Zn 0 particles were prepared, characterized and used as Fenton-like catalyst for the degradation of sulfamethoxazole (SMX). The results showed that Cu 0 /Zn 0 particles were capable of converting O 2 to H 2 O 2 , O 2 − and OH radicals. In bimetallic Cu 0 /Zn 0 particles, Cu 0 /Zn 0 corrosion cells were formed through the direct contact of Zn 0 and Cu 0 , which not only accelerated the electron transfer from Zn 0 to O 2 , leading to the promotion of H 2 O 2 generation, but also enhanced the conversion of Cu 2+ to Cu + /Cu 0 , facilitating the catalytic decomposition of H 2 O 2 to produce O 2 − and OH radicals. SMX could be efficiently degraded in Cu 0 /Zn 0 -air system over a broad pH range from 3 to 9, the removal efficiency of SMX and TOC was 87.8% and 45.5%, respectively at following condition: SMX concentration, 20 mg/L; dosage of bimetallic Cu 0 /Zn 0 particles (mole ratio of Zn to Cu was 1:2), 2 g/L; air flow rate, 1.8 L/min; reaction temperature, 25℃ and without adjusting pH. The recycling use of bimetallic Cu 0 /Zn 0 particles leaded to the enhanced degradation of SMX due to the newly formed cuprous oxide (Cu 2 O), which could further catalytically activate O 2 . The quenching experiment showed that the concentration of dissolved oxygen could significantly affect the main reactive oxidant species (ROSs). Additionally, the intermediate products of SMX degradation were detected and a possible pathway of SMX degradation as well as the catalytic mechanism of Cu 0 /Zn 0 -air system were proposed.
