Conventional slow-release urea fertilizers often rely on polymeric coatings, which can be costly, non-biodegradable, and environmentally problematic. To address these limitations, we developed a slow-release urea fertilizer using a combination of biodegradable polymeric (specifically polyvinyl alcohol/starch film) and biochar-based organic coatings, designated as U-PVA/ST/BOF. The slow-release performance of this fertilizer was evaluated through column leaching tests, where U-PVA/ST/BOF exhibited the most effective slow-release characteristics, with the lowest cumulative nitrogen release rate (18.3 %) over 28 days, while U/BOF (lacking the polymeric coating) released 36.4 %, while U-PVA/ST (without the biochar-based organic coating) released 42.7 %. Mechanistic investigations revealed that biochar-based organic coating in U-PVA/ST/BOF acts as a barrier, slowing water penetration and preventing premature swelling of the PVA/ST membrane. As water gradually diffuses through the biochar-based organic layer, the PVA/ST matrix absorbs moisture and swells, thereby releasing nitrogen in a sustained manner. Field trials showed that U-PVA/ST/BOF significantly improved wheat growth, grain-setting rate, and yield, resulting in a 40 %-44 % increase in yield compared to other fertilization treatments. Economic analysis indicated that U-PVA/ST/BOF provides a cost-effective solution for reducing nitrogen inputs, potentially lowering global nitrogen use by up to 29.75 million tons, offering both ecological benefits and economic viability for global agricultural systems.

Lithium extraction from brines with the high Mg 2+ /Li + ratio is crucial for sustainable lithium resource and environmental protection. This study incorporated the classic tributylphosphate (TBP)/FeCl 3 system into the polyvinyl chloride (PVC) based polymer inclusion membrane (PIM) to extract Li + from the solution which is rich of Mg 2+ (The initial Mg 2+ /Li + molar ratio is 15). The morphology and composition of PIMs were characterized systematically, and the content of TBP/FeCl 3 carrier in the PIM was optimized. Compared to liquid-liquid extraction, the extraction ratio of Li + for PIM extraction increases by 20% and the separation factor of Li + over Mg 2+ increases by 5%. Besides, the loss ratio of Fe 3+ after one loop of liquid-liquid extraction is 17.79%, which is close to that of PIM extraction after three loops (18.30%), demonstrating that the PIM showed a good stability. Furthermore, the separation factor of Li + over Mg 2+ for the PIM with 50 wt% TBP/FeCl 3 is as high as 176 and the initial flux for Li + is 8.12 × 10 −4 mol m −2 h −1 . This study displays a TBP/FeCl 3 based PIM with high selectivity for Li + , providing a possible membrane technology for lithium extraction from brines.

In the present study, BiVO4sample was prepared under different pH 0.5–13 without capping agent. Different morphology characteristics were observed, such as sheet crystal structure, cross crystal structure and branching crystal structure. The mechanism of the formation of BiVO4nanostructure was discussed. Under acid condition, sheet crystal structure was obtained. The phenomenon could be attributed to polymerization of vanadate in the presence of H+. In the weak alkaline solution, across structure and branching type morphology was obtained. The photocatalytic efficiency for the samples ranked as pH 5 > pH 3 > pH 7 > pH 9 > pH 1 > pH 11 > pH 13 > blank, which is in good agreement with X-ray diffraction (XRD) result.E. colienvelop was damaged in the presence of BiVO4under visible light. The protrusion on envelop was diminished by BiVO4. Attenuated Total Reflection Fourier transformed Infrared Spectroscopy (ATR-FTIR) results suggested the intensity was weakened for the amide, phosphoric, –COO−group and C-H bond in lipopolysaccharides (LPS), peptidoglycan and periplasm molecules.Keywords:BiVO4;monoclinic scheelite structure;photocatalytic efficiency;E. coli;envelop

Valvular heart disease (VHD) poses a thorny problem in cardiovascular diseases. The most effective treatment for VHD is heart valve replacement. Biological heart valve (BHV) is more favored than mechanical heart valve due to the maturity of transcatheter heart valve replacement (THVR) and the absence of the need for lifelong anticoagulant use. However, traditional commercial BHV suffers degeneration within 10 to 15 years because of calcification caused by the cross-linking reagent, glutaraldehyde. Considering the remarkable properties of POSS, PEG, and the star-like eight-arm structure, we fabricated POSS-PEG-PP, which is a decellularized porcine pericardium (DPP) crosslinked by a star-like eight-arm cross-linker octafunctionalized POSS of benzaldehyde-terminated polyethylene glycol (POSS-PEG-CHO) based on the Schiff's base reaction. POSS-PEG-PP exhibits more intense fiber arrangement and better mechanical properties than GLUT-PP (glutaraldehyde crosslinked DPP). The results also show that the cytocompatibility, endothelialization, and hemocompatibility of POSS-PEG-PP are outstanding in vitro. Subsequently, in vivo assessments demonstrate that POSS-PEG-PP has anti-inflammatory and anti-calcification abilities. Furthermore, RNA sequencing analysis of subcutaneous implants suggests that the intervention of AMPK and IL-17 signaling pathways plays an important role in the inflammatory and immune responses regulation of POSS-PEG-PP. Therefore, POSS-PEG-PP is an excellent substitute material for BHVs and is expected to be clinically transformed.

Viruses are the most abundant microorganisms on the earth, their existence in contaminated waters possesses a significant threat to humans. Waterborne viral infections could be fatal to sensitive population including young child, the elderly, and the immune-compromised. It is imperative to remove viruses during water treatment to better protect public health, especially in the light of evidence of detection of coronaviruses genetic fragments in raw sewage. We reported bench-scale experiments evaluating the extent and mechanisms of removal of a model virus (spring viremia of carp virus, SVCV) in water by adsorption. Microspheres made by boronic acid-modified bacterial cellulose with excellent mechanical strength were successfully fabricated as packing materials for the column to remove glycoproteins and enveloped viruses from water. The synthesized adsorbent was characterized by attenuated total reflectance Fourier transform infrared (ATR-FTIR) spectroscopy, Atomic Force Microscopy (AFM), Scanning Electron Microscopy (SEM), and Brunauer Emmett Teller (BET) measurement. The adsorption efficiency of glycoproteins was investigated by SDS-PAGE and the Broadford protein assay, while the binding capacity with the virus (spring viremia of carp virus) was monitored by cell culture to calculate the viral cytopathic effect and viral titer caused by the virus. The data obtained from the above experiments showed that ∼3-log removal of SVCV in 3 h, which significantly reduced the virus concentration from microspheres packed column. The present study provides substantial evidence to prove beyond doubt that material based on bacterial cellulose seems to have the potential for virus removal from water which can be extended to systems of significant importance.

Although various eco-friendly and sustainable biobased polyurethane-coated controlled-release fertilizers (BPCFs) have been developed, their applications were limited by the bio-based coating contained many microscopic holes. In this work, a nano-soy-protein microcapsule-enabled self-healing biopolyurethane-coated controlled-release fertilizer (NSBCF) with enhanced controlled-release performance was fabricated. Nanoscale soy-protein microcapsules (SMCs) were prepared from soy-protein isolate (SPI) and poly (lactic-co-glycolic acid) using the water-oil-water emulsification technology. The self-healing biopolymer coatings of NSBCF with uniformly dispersed SMCs were constructed through self-assembly. The controlled-release longevity of NSBCF was >28 days longer than that of the BPCF with the unmodified coating. The self-healing mechanism of NSBCF was determined by directly observing the restoration area and the 3D pore distribution of coating using fluorescence labeling and X-ray computed tomography . After being released from the SMCs, SPI self-repaired the coating by reacting with glutaraldehyde to form solid resins to clog the microscopic holes. The SMCs-enabled self-healing process successfully reduced the nutrient release rate and extended the nutrient release longevity of NSBCF. This novel biobased controlled-released fertilizer with self-healing function represents a new direction for the development of high efficiency and environmentally friendly fertilizers to improve agriculture and food sustainability .

This work prepared a lignin-based double-layer slow-release fertilizer (SRF). We prepared sodium alginate-zinc ammonium phosphate microbeads as the inner core of fertilizer by ion exchange method, cellulose acetate butyrate (CAB) co-blended with degradable material polylactic acid (PLA) as the inner coating, and two chemically modified lignin (sulfonated lignin and epoxy-aminated lignin) as the second coating. The synthesized Materials were characterized morphologically and structurally by FTIR, TG, XRD and SEM. The viscosity, mechanical property, water contact angle, water-holding property, water-retention and slow-release property of the samples were evaluated. PC-SRF, PSC-SRF and PEC-SRF all had superior water-retention and nutrient release property compared to sodium alginate-zinc ammonium phosphate. The release of urea and phosphorus in the single-layer PC-SRF reached equilibrium after 34 and 36 days, and their cumulative release rates reached 87.09% and 86.19%, respectively. The release of urea and phosphorus from the bilayer PSC-SRF reached equilibrium after 38 and 40 days, and the cumulative release rates reached 83.57% and 82.07%, respectively; the release of urea and phosphorus from the bilayer PEC-SRF prepared under the same conditions reached equilibrium after 38 and 42 days, and the cumulative release rates reached 81.47% and 81.66%, respectively.

Implant-based breast reconstruction is frequently complicated by capsular contracture and surgical-site infection. Current mesh materials are unable to effectively address these complications due to inherent limitations. This study introduces a novel dual-layered mesh composed of a shape-memory polyurethane foam (PUF) base and a magnolol-loaded nanofiber (PG-MA) outer layer. The PUF-PG-MA mesh offers mechanical support, sustained antibacterial activity against Staphylococcus aureus, and anti-inflammatory effects by reducing TNF-α and IL-1β levels. In vitro characterization demonstrated a microtextured surface topography (Ra = 11.4 μm), biphasic drug release profile (65.0 ± 4.5% released within 24 hours; 79.9 ± 3.2% by 7 days), excellent shape recovery (>94.5% after cyclic strain), and cytocompatibility (cell viability >80%). Importantly, in an infected breast reconstruction model, PUF-PG-MA resulted in significantly thinner capsules (160.86 ± 96.21 μm) compared to controls (PUF: 257.88 ± 76.27 μm; PUF-PG: 192.34 ± 71.06 μm), demonstrating its dual capacity to suppress infection-induced fibrosis and capsular contracture. This integrated design represents a promising strategy for improving long-term outcomes in breast reconstruction.

Enveloped viruses encased within a lipid bilayer membrane are highly contagious and can cause many infectious diseases like influenza and COVID-19, thus calling for effective prevention and inactivation strategies. Here, we develop a diatomic iron nanozyme with lipoxidase-like (LOX-like) activity for the inactivation of enveloped virus. The diatomic iron sites can destruct the viral envelope via lipid peroxidation, thus displaying non-specific virucidal property. In contrast, natural LOX exhibits low antiviral performance, manifesting the advantage of nanozyme over the natural enzyme. Theoretical studies suggest that the Fe-O-Fe motif can match well the energy levels of Fe 2 minority β-spin d orbitals and pentadiene moiety π* orbitals, and thus significantly lower the activation barrier of cis , cis -1,4-pentadiene moiety in the vesicle membrane. We showcase that the diatomic iron nanozyme can be incorporated into air purifier to disinfect airborne flu virus. The present strategy promises a future application in comprehensive biosecurity control.

Here, a novel Ag quantum dots (Ag QDs) with diameter 3.1–10 nm modified Bi 4 O 5 Br 2 composite system was firstly fabricated via the facile mechanical agitation method and the photocatalytic ability of Ag QDs/Bi 4 O 5 Br 2 was evaluated by disinfection towards Escherichia coli ( E.coli ) under visible light stimulation (λ > 420 nm). The Ag QDs/Bi 4 O 5 Br 2 composites displayed the superior photocatalytic disinfection ability to the pure Bi 4 O 5 Br 2 . Especially, the 1000 Ag QDs/Bi 4 O 5 Br 2 composite exhibited the strongest photocatalytic ability with disinfecting all bacteria (1 × 10 7 cfu/mL) after 180 min visible light irradiation. The promoted photocatalytic ability of 1000 Ag QDs/Bi 4 O 5 Br 2 mainly be attributed to the synergistic effect of SPR produced by Ag and the formation of Schottky barrier which facilitate the separation efficiency of charge carrier and light utilization. The mechanism of photocatalytic disinfection over the Ag QDs/Bi 4 O 5 Br 2 composite was that the generated active species h + (hole) and · O 2 − (superoxide radical) disrupted the cell envelop to induce the leakage and decomposition of the cellular substances (e.g. protein, deoxyribonucleic acid (DNA) and potassium ion (K + )) as validated with the multiple techniques. This work open a new horizon to develop high-efficient Bi m O y X n -based photocatalytic disinfection materials.

The protective effects of histone deacetylase (HDAC) inhibitors were highlighted in the treatment of kidney diseases, especially acute kidney injury (AKI). However, the currently available HDAC inhibitor cannot be delivered to the kidney properly because of its poor solubility in aqueous solutions. Therefore, calcium alginate (Ca-ALG) microspheres were proposed as microcarriers for the delivery of HDAC inhibitors in this study. First, Ca-ALG microspheres with high sphericity were obtained by a single-emulsion microfluidic strategy. Then, we selected suitable Ca-ALG microspheres for HDAC inhibitor loading by analyzing the swelling ratio and the release property using different parameters. Besides, thermal stimulation will change the drug release property of Ca-ALG microspheres in in vitro experiments. Furthermore, the HDAC inhibitor-loaded microspheres were delivered to the kidney by renal subcapsular injection for evaluating the treatment effects in mice with ischemia-reperfusion-induced AKI. The in vivo results showed that the HDAC inhibitor-loaded Ca-ALG microspheres could effectively reduce the renal regional inflammatory response and macrophage infiltration. Taken together, we proposed a promising therapy with an effective kidney-targeted drug delivery for the treatment of AKI.

Porcine reproductive and respiratory syndrome virus (PRRSV) is a typical immunosuppressive virus devastating the global swine industry. DEAD-box helicases (DDXs) are a family of ATP-dependent RNA helicases that are predominantly implicated in modulating cellular RNA metabolism. Meanwhile, a growing number of studies have suggested that some DDXs are associated with innate immunity and virus infection, so they are considered potential antiviral targets. Herein, we screened 40 DDXs and found that ectopic expression of DDX10 exhibited a significant anti-PRRSV effect, while DDX10 knockdown promoted PRRSV proliferation. Further analysis revealed that DDX10 positively regulates type I interferon production, which may contribute to its anti-PRRSV effect. Interestingly, PRRSV infection promoted DDX10 translocation from the nucleus to the cytoplasm for macroautophagic/autophagic degradation to block the antiviral effect of DDX10. By screening PRRSV-encoded proteins, we found that the viral envelope (E) protein interacted with DDX10. In line with the autophagic degradation of DDX10 during PRRSV infection, E protein could induce autophagy and reduce DDX10 expression in wild-type cells, but not in ATG5 or ATG7 knockout (KO) cells. When further screening the cargo receptors for autophagic degradation, we found that SQSTM1/p62 (sequestosome 1) interacted with both DDX10 and E protein, and E protein-mediated DDX10 degradation was almost entirely blocked in SQSTM1 KO cells, demonstrating that E protein degrades DDX10 by promoting SQSTM1-mediated selective autophagy. Our study reveals a novel mechanism by which PRRSV escapes host antiviral innate immunity through selective autophagy, providing a new target for developing anti-PRRSV drugs.Abbreviations: ACTB: actin beta; ATG: autophagy related; co-IP: co-immunoprecipitation; CQ: chloroquine; DDX10: DEAD-box helicase 10; E: envelope; EGFP: enhanced green fluorescent protein; hpi: hours post infection; hpt: hours post transfection; IFA: indirect immunofluorescence assay; IFN-I: type I IFN; IFNB/IFN-β: interferon beta; IRF3: interferon regulatory factor 3; ISGs: interferon-stimulated genes; KO: knockout; MAP1LC3B/LC3: microtubule associated protein 1 light chain 3 beta; mAb: monoclonal antibody; MOI: multiplicity of infection; NBR1: NBR1 autophagy cargo receptor; NFKB/NF-κB: nuclear factor kappa B; OPTN: optineurin; ORF: open reading frame; PRRSV: porcine reproductive and respiratory syndrome virus; SeV: sendai virus; siRNA: small interfering RNA; SQSTM1/p62: sequestosome 1; TCID50: 50% tissue culture infective dose; WT: wild type.
