Nearly 1.3 billion tons of food are discarded annually in the production process. In this study, a novel slow-release nitrogen fertilizer with water absorbency was developed using leftover rice and crosslinking methods. Urea was incorporated as the nitrogen source in a leftover rice-g-poly(acrylic acid)/montmorillonite (LR-g-PAA/MMT) network, and then the leftover rice-g-poly(acrylic acid)/montmorillonite/Urea (LR-g-PAA/MMT/Urea) retained in the soil, and used as the loss control agent for water and nutrients. Variables including concentrations of acrylic acid , montmorillonite , N,N´-methylenebis acrylamide (MBA), and potassium persulfate (KPS) were investigated. Samples were with a water absorbency of 102.6 g/g in distilled water and 25.1 g/g in 1.0 wt% NaCl solution under optimized conditions. Swelling measurements and water-retention indicated that higher-covalent cations would aggregate the hydrogels and decrease swelling. Investigating leaching behavior showed that these samples have the potential to carry the necessary nitrogen (N). The results demonstrated that the LR-g-PAA/MMT/Urea had a low leaching losses of N (19.7%) compared with pure urea (52.3%). Therefore, the developed fertilizer may be widely applicable in agriculture and horticulture , and could provide a new platform for reusing leftover rice.

A novel controlled release fertilizer was developed using interpenetrating polymer network (IPN) as the coating material. The IPN was successfully sprayed on the surface of the urea particles to form IPN-coated fertilizers (IPNCU) for controlled nitrogen release. The IPN was synthesized by bio-based polyamide (PA) from d -glucaric acid and epoxy (EP) through network interpenetrating. The chemical structure and microscopic morphology characteristics of IPN were examined by Fourier transform infrared spectroscopy, 1 H-nuclear magnetic resonance, and scanning electron microscopy. The property of IPN with the different PA/EP mass ratios were investigated and compared with that of EP-coated fertilizers (EPCU). The nutrient release behaviors of IPNCU in water and soil were detected. The results showed that the IPNCU with 5% PA content increased the nitrogen release longevity by 41 days, raised the water contact angle of surface by 23.9°, and then significantly slowed the nitrogen release rate of the IPNCU. The nutrient release mechanism of IPNCU was discussed in detail. This work indicated that the environment-friendly IPN with superior controlled release properties could be especially useful in horticultural and agricultural applications. © 2017 Wiley Periodicals, Inc.

L -CNF-reinforced hydrogel electrolyte achieves 336 mS cm −1 conductivity and 320% stretchability. • Flexible Zn-air battery delivers 50.5 mW cm −2 power density and 33 h cycling stability. • Integrated system enables on-demand drug release and wearable sensing, expanding biomass applications. Conductive hydrogels with high ionic conductivity, excellent mechanical properties and excellent water retention are still widely concerned in the field of flexible electronics. In this study, a low-cost, green and simple modification strategy was used to prepare a double-crosslinked alkaline hydrogel electrolyte composed of lignin-containing cellulose nanofibrils ( L -CNF), polyvinyl alcohol (PVA) and polyacrylamide (PAM) to improve the performance of flexible zinc-air batteries (FZABs). The mechanical properties of the hydrogel, ionic conductivity, and water retention capacity were optimized through varying the additive amounts of L -CNF. The findings indicate that the composite hydrogel electrolyte exhibits optimal performance at an L -CNF content of 0.15 g，exhibiting an ionic conductivity as high as 336.42 mS cm −1 , water retention of 52% after 10 days, and tensile strain of 320% under 70 kPa stress. The FZABs based on this hydrogel electrolyte achieved a peak power density of 50.5 mW cm −2 , demonstrated stable discharge for 689 min at 2.0 mA cm −2 , and displayed cycling stability over 33 h. The hydrogel electrolyte has excellent flexible sensing performance with a gauge factor of 3.10. In this work, green and low-cost biomass L -CNF is used as a functional modification filler, which provides a new design idea for the multifunctional integration of biomass resources in flexible energy devices.

This study aimed to investigate the cooperative effects of protonation combined with pulsed electric field (PEF) treatment on the conformational changes of goose myofibrillar proteins (MPs) and their flavor-controlled release behavior. Structural variations in MPs were characterized by circular dichroism, Fourier transform infrared spectroscopy, and surface hydrophobicity (H 0 ) detection. The binding mechanism between MPs and typical flavor compounds was further explored via molecular docking. Results demonstrated that protonation disrupted the intramolecular ionic bonds and hydrogen bonds of MPs, increasing their sensitivity to subsequent PEF treatment. The synergistic protonation-PEF treatment induced a significant transition from α-helix to β-sheet structure, accompanied by a remarkable increase in surface hydrophobicity. Molecular docking confirmed that key amino acid residues (Asp97, Gln95) were primarily responsible for the enhanced binding capacity of MPs to hydrophobic flavor compounds. This work provides mechanism insights into the cooperative regulation of protonation and PEF on the structure and flavor-binding capacity of goose MPs, providing scientific support for the control of flavor release in processed goose products.

This study develops MOF patches for controlled NO release in produce preservation. • MOF loading effectively protects NO donors from loss during wet-casting fabrication. • Three metal-node MOF patches enable differential NO release profiles. • Patch integrates moisture absorption, microorganism and respiration inhibition. • MOF patches significantly extend produce shelf life while reducing precursor loss. Nitric oxide (NO) preservation suffers from instability and safety issues via conventional single-exposure treatments, while wet-casting methods cause substantial NO donor loss. This study developed metal-organic framework (MOF)-mediated controlled-release patches to address these limitations. Three MOFs (Cu-MOF, Zn-MOF, Fe-MOF) with distinct pore structures were synthesized, achieving 26.9%–38.2% L-arginine loading. The resulting gelatin-polyacrylic acid sodium hydrogel patches exhibited tensile strength of 3.03–4.84 MPa and elongation at break of 131.3%–240.1%, and dissolution rates of 12.4%–17.2%. They also showed significant antimicrobial activity against E. coli, S. aureus, and A. niger . MOF loading elevated precursor utilization efficiency to 70%–82.5%. The patches achieved sustained release of H₂O₂ (8.0–9.6 mmol/g) and NO (41.7–50.6 ppm) over 12 days, extending cherry tomato shelf life to 12 days at room temperature while maintaining total bacterial levels within safe limits. This work establishes MOF-mediated controlled release for green preservative gas utilization. Download: Download high-res image (189KB) Download: Download full-size image

The maturation of biobased polymer synthesis process has led to the rapid adoption of biobased controlled-release fertilizers (BCRFs). Despite this progress, the loose structure, low cross-linking density, and poor water repellency of current biobased coatings result in short controlled-release periods, which do not meet the long-term nutrient demands of crops throughout their reproductive phases. Moreover, existing modifications to address these issues often involve the addition of external additives, which can increase biotoxicity and cost. In this study, castor oil-based hyperbranched polyol (COHBPs) was synthesized from castor oil (CO) using a “one-pot method.” We report the development of high cross-linking density biobased hyperbranched polyurethane (COHBPPFs) as a coating for BCRFs. Gel content and SEM analysis demonstrated that COHBPPFs exhibited a high degree of cross-linking. Mechanical testing using an electronic universal testing machine, along with AFM results, highlighted the superior mechanical properties of COHBPPFs compared to traditional coatings. COHBPPFs significantly enhanced controlled release performance, with a 3% coating content providing nearly 50 days of controlled release, a marked improvement over conventional coatings. The controlled release mechanism of COHBPPFs was elucidated by modeling the cross-linking process of COHBPs with PAPI. This study offers a comprehensive examination of CRF coatings from multiple perspectives and provides valuable insights into the development of high cross-link density, environmentally friendly, and renewable biobased CRFs.

Mycotoxins are representative contaminants causing food losses and food safety problems worldwide. Thymol can effectively inhibit pathogen infestation and aflatoxin accumulation during grain storage, but high volatility limits its application. Here, a thymol-betaine co-crystal system was synthesized through grinding-induced self-assembly. The THY-TMG co-crystal exhibited excellent thermal stability with melting point of 91.2 °C owing to abundant intermolecular interactions . Remarkably, after 15 days at 30 °C, the release rate of thymol from co-crystal was only 55%, far surpassing that of pure thymol. Notably, the co-crystal demonstrated the ability to bind H 2 O in the environment while controlling the release of thymol, essentially acting as a desiccant . Moreover, the co-crystals effectively inhibited the growth of Aspergillus flavus and the biosynthesis of aflatoxin B 1 . In practical terms, the THY-TMG co-crystal was successful in preventing AFB 1 contamination and nutrients loss in peanuts, thereby prolonging their shelf-life under conditions of 28 °C and 70% RH.

Sogatella furcifera ( S. furcifera ) is a serious pest of rice in China. Excessive use of conventional insecticides has led to environmental pollution and other associated issues. The rapid advancement of nanotechnology offers new perspectives for developing innovative pest management strategies. Therefore, we designed a nanopesticide system in which dinotefuran (DNF) was encapsulated within chitosan (CS) and further integrated with ZnO quantum dots (ZnO QDs). The resulting formulation (DNF@CS-P-ZnO) displayed an average particle size of 33.3 nm and a loading efficiency of 17.74 %. Under acidic conditions (pH 5), about 74.93 % of DNF was released within 96 h, showing a controlled release profile. Bioassays confirmed high insecticidal activity, with mortality reaching 93.67 % after 4 d. Mechanistic analyses indicated that the nanoformulation inhibited cytochrome P450 activity and downregulated resistance-related genes ( CYP417A2 , CYP439A3 , CYP4CE3 ), thereby enhancing susceptibility to insecticides. Additionally, the formulation exhibited effective translocation within both pests and rice plants, improved photostability, enhanced wettability, and minimal impact on non-target organisms. Overall, DNF@CS-P-ZnO represents a promising nanopesticide platform that improves pesticide efficacy while reducing environmental risks, offering potential for sustainable rice pest control.

Inefficient use of pesticides and the consequent environmental problems have led to the development of low-cost, environment-friendly and efficient pesticide delivery systems. Pickering emulsions (PK) stabilized by zein are considered to have many application prospects in the delivery of pesticides. Herein, the function of zein was improved by non-covalent binding with sodium abietate (RA-Na). Tea tree oil (TTO) was used as the solvent for hydrophobic photosensitive pesticide, avermectin (AVM), and also as a component of the oil phase of emulsion. The emulsion AVM@PK was oil in water (O/W) type that had certain foliar affinity. Under the same conditions of UV irradiation, the AVM residual rate of AVM@PK system was 2.4 times that of commercial emulsion (EC), showing superior UV resistance. AVM@PK released AVM at a faster rate under acidic/ basic conditions in vitro than under neutral conditions, with a certain pH response. In vitro bioactivity tests showed that AVM@PK had good antibacterial activity and insecticidal activity equivalent to EC. This system is expected to be used to prevent some plant pests while also preventing or treating some bacterial diseases. It is a simple, environment-friendly, low-cost, effective, and practical strategy for pesticide delivery.

Intelligent responsive controlled release systems have demonstrated considerable potential for enhancing pesticide utilization efficiency and mitigating environmental pollution. In this study, hollow carbon spheres (HCMS) with different internal structures were synthesized, exhibiting excellent drug loading capacity and remarkable photothermal conversion performance. The PNIPAm@HCMS was successfully synthesized by encapsulating mepiquat chloride (DPC) within HCMS using the temperature-sensitive polymer poly-isopropylacrylamide(PNIPAm) as an intelligent encapsulation layer. The internal structure of HCMS, the successful loading of DPC drug and coating of PNIPAm thermosensitive shell were proved by SEM, TEM and FT-IR analysis. The release behavior study indicates that the release model of the composites at varying temperatures adheres to the Ritger-Peppas model, with the release mechanism mainly controlled by the internal diffusion of the particles. Furthermore, near-infrared (NIR) irradiation experiments confirmed that the PNIPAm@HCMS nanocomposites possess light controlled release properties. Among them, HCMS functions as an antenna for photothermal conversion, while PNIPAm serves as an intelligent regulator of drug release. The anti-scouring experiment and contact angle measurement indicated that PNIPAm also enhanced the washing resistance of the composites. The practical application of the composite was verified by pot experiment of peanut. This research offers novel perspectives for the development of photo responsive intelligent controlled release pesticides.

Antimicrobial active packing has demonstrated great potential in extending food shelf life. However, developing new intelligent and responsive antimicrobial strategies is still desirable. Here, a 2-hydroxy-4-methoxybenzaldehyde (HMB)-decorated chitosan film (HDCF) via surface Schiff-base coupling is designed. HDCF shows excellent storage stability and pH-responsive release, enabling a switch in antimicrobial mode from “defense” to “attack” under acid conditions. Before HMB release, HDCF exhibits broad spectrum antifungal adhesion capabilities against Penicillium citrinum , Penicillium chrysogenum and Aspergillus niger , and antibacterial adhesion capabilities against Staphylococcus aureus . Under acidic conditions, with HMB release, HDCF displays enhanced release-antifungal performance against A. niger , P. citrinum and Candida albicans and release-antibacterial performance against S. aureus . In addition, HDCF is effective in food preservation for cherry tomatoes and tomato juice and has good UV barrier properties. Therefore, this HDCF provides a new path for diversiform antimicrobial designs in the new generation of food packaging.
