Fresh meat is rich in nutrients and, compared to frozen meat, offers a more flavorful taste, making it a common ingredient in daily life. However, during storage, fresh meat exudes natural juices. The abundant moisture and nutrients in these juices promote microbial proliferation, thereby accelerating meat spoilage. Therefore, controlling microbial contamination during the storage, transportation, and preservation of fresh meat is particularly important. Among various antimicrobial materials, N -halamine-based antimicrobial materials have gained increasing research attention in recent years due to their excellent characteristics, such as broad-spectrum antimicrobial activity and renewable functional groups. This study investigates the potential application of N -halamine polymers in antimicrobial packaging for fresh meat preservation. The results show that incorporating N -halamine antibacterial polymers (PAMPS-Cl) into absorbent pads exhibits outstanding antibacterial performance (sterilization rate>99.99%). Subsequent application studies on fresh meat preservation indicate that N -halamine-based antimicrobial packaging materials can significantly reduce the total microbial count in fresh meat, thereby improving its sensory qualities. The shelf life of fresh meat can be extended to the 8th days at 4 °C, prolonging the shelf life compared to the group without preservation treatment, where the total bacterial count exceeded the microbiological limit for fresh meat between the 4th and 6th days. This highlights their considerable potential for research and practical application in the fields of fresh meat packaging and preservation.

The density ( ρ ) and dynamic viscosity ( η ) of ternary system containing n -dodecane, isobutanol and ethyl decanoate and three binary mixtures ( n -dodecane + isobutanol), ( n -dodecane + ethyl decanoate), (isobutanol + ethyl decanoate) were experimentally determined in a temperature range of T = (293.15 to 323.15 K) with a temperature step of 5 K and at pressure 0.1 MPa. The excess molar volume ( V m E ), deviation in viscosity (Δ η ) and excess free energies of activation of viscous flow (Δ G ∗E ) of ternary and the corresponding binary systems were obtained from the ρ and η data. Additionally, Redlich–Kister equation, Cibulka equation and Singh equation were used to estimate V m E and Δ η of ternary mixtures. The V m E exhibites positive values for all binary and ternary mixtures, and the Δ η and Δ G ∗E values are all negative. Achieving a thorough comprehension of biofuel density and viscosity properties is important for researching and developing suitable surrogate fuel mixtures.

Interfacial polymerization (IP)-based nanofiltration (NF) membranes often suffer from the permeability–selectivity trade-off due to uncontrolled monomer diffusion and nonuniform polyamide (PA) layer formation. In this work, a g-C₃N₄/polyethyleneimine (PEI) hybrid interlayer was constructed on a polyethersulfone substrate via vacuum-assisted deposition to regulate interfacial polymerization and enhance sulfate separation performance for nanofiltration-related water softening applications. The synergistic interaction between g-C₃N₄ nanosheets and PEI effectively suppressed nanosheet aggregation, enlarged interlayer spacing, and improved interfacial compatibility, thereby promoting the formation of an ultrathin and highly cross-linked PA selective layer. The optimized TFNi-2 membrane exhibited a high water flux of 65.8 L·m⁻²·h⁻¹ together with a Na 2 SO 4 rejection of 96.8% at 0.4 MPa, demonstrating excellent permeability and selective rejection toward multivalent ions. Structural characterizations confirmed that the g-C₃N₄/PEI interlayer regulated amine diffusion behavior and suppressed nonuniform PA formation, resulting in a compact and defect-suppressed selective layer with an MWCO of approximately 600 Da. In addition, the highly permeable interlayer generated a favorable “gutter effect” that reduced transport resistance and facilitated water permeation. The optimized membrane also exhibited satisfactory chlorine resistance and long-term operational stability. This work provides new insights into interlayer-regulated interfacial polymerization for the development of high-performance nanofiltration membranes for sulfate removal and water softening applications.

This study presents a fiber-optic humidity sensor based on boron and nitrogen co-doped graphene quantum dots (B,N-GQDs). Hydrophilic B,N-GQDs film was fabricated by a hydrothermal method, followed by photo-driven deposition on plastic optical fiber cores. The sensor showed a wide response range (0–85%RH) with high sensitivity (0.0072/%RH), a low detection limit (0.2%RH), high linearity (${R^2} = {0.999}$), and rapid response (2.5 s). The sensor exhibited a low hysteresis and excellent stability. Good stability and promising applications in respiration and skin moisture monitoring were also demonstrated. The sensing mechanism is attributed to humidity-dependent adsorption of water molecules by the abundant hydrophilic groups of the film. This adsorption alters the film’s refractive index and extinction coefficient, modulating the transmitted light intensity via a partial leaky-mode mechanism.

Lithium–sulfur (Li–S) batteries are promising next-generation energy storage systems due to their high theoretical capacity and low cost, but they suffer from the insulating nature of sulfur, significant volume change, and the polysulfide shuttle effect. To address these challenges, we designed and synthesized a CeO 2 -decorated N-doped reduced graphene oxide (N-rGO/CeO 2 ) composite as a sulfur host. The N-rGO framework ensures high electrical conductivity and offers abundant active sites for sulfur species, while the CeO 2 nanoparticles, with their Ce 4+ /Ce 3+ redox couple, effectively immobilize polysulfides and catalyze their conversion. This unique structure couples a highly conductive N-rGO network with uniformly dispersed nanoparticles, resulting in a synergistic system that integrates physical confinement, strong chemisorption, and efficient electrocatalysis. N-rGO/CeO 2 /S cathode delivers a high initial discharge capacity of 1330.9 mAh g −1 at 0.1C and maintains 730.0 mAh g −1 after 100 cycles at 0.2C. Remarkably, it exhibits outstanding long-term cyclability, retaining capacities of 432.4 and 327.0 mAh g −1 after 1000 cycles at 1 C and 3 C, respectively, corresponding to an ultralow capacity decay rate of only 0.024% per cycle at 1 C. This work highlights the effectiveness of the N-rGO/CeO 2 composite as a multifunctional host for high-performance Li–S batteries.

The extraction of chitin/chitosan from biowaste shrimp shells involves the heavy use of strong acids and alkaline solutions, resulting in a series of decomposed amino acids in the extraction waste. Herein, we demonstrate a new strategy to grow FeNi nanoalloys encapsulated in nitrogen-doped carbon nanotubes (3FeNi-NCNTs) at a high percentage by sintering the extracted amino acids, FeCl 3 , NiCl 2 and melamine at 900 ℃ in N 2 . The FeNi-NCNT exhibits a competitive limiting current density in oxygen reduction reaction (ORR) to the commercial 20% Pt/C, with the onset potential and half-wave potential at 0.98 V and 0.84 V versus RHE. The oxygen evolution reaction (OER) performance also rivals the RuO 2 catalyst, and the overpotential (E j =10 mAcm -2 - E 1/2 ) of as low as 0.76 V, highlighting a green pathway to yield superior bifunctional catalysts at low cost. When used in zinc-air batteries (ZABs), the aqueous ZAB showed excellent cyclic and rate performance, together with the peak power density and specific capacity of 173.6 mW cm -2 and 809.9 mAh g -1 (corresponding to an energy density of XXX Wh kg -1 based on the mass of consumed zinc); and the flexible ZAB with a polyacryl-amide hydrogel electrolyte also exhibited a high peak power density of 133 mWcm -2 and a long cycle life of 140 h, superior to the reference Pt/RuO 2 -based ZABs, highlighting a sustainable biowaste upcycling of shrimp shell valorization on energy storage.

In the study, we present a molten salt-assisted hard-templating strategy for synthesising cobalt and nitrogen-doped carbon nanoflowers (Co/N-CNFs) as high-performance electrocatalysts for highly sensitive and selective electrochemical dopamine detection. The hierarchical surface roughness and excellent conductivity of Co/N-CNFs, combined with their uniformly dispersed Co sites, facilitate exceptional electrocatalytic performance toward dopamine oxidation. Electrochemical measurements demonstrated that the Co/N-CNFs composite exhibited outstanding performance for dopamine sensing, featuring a broad linear response range from 1 to 1000 µM and an exceptionally low detection limit of 0.13 µM. Moreover, the sensor exhibited remarkable stability, excellent anti-interference capability, and high accuracy in actual sample analysis. The work presents an innovative design strategy for Co/N-doped carbon catalytic systems, enabling the detection of dopamine in spiked human serum samples.

Photocatalytic CO 2 reduction to C 2 H 4 remains challenging due to inefficient multielectron transfer and sluggish C−C coupling kinetics. Herein, we demonstrate that precise engineering of metal−organic framework (MOF) nodes establishes dual-functional active sites that synergistically drive C−C coupling and H 2 O activation. A hybrid photocatalyst is constructed by integrating a porphyrinic MOF (Fe-MOFBPy), featuring axially coordinated bipyridine ligands that modulate paddlewheel Fe−N nodes, with carbon nitride (CN) to form a heterojunction. Controlled linker depletion introduces defects that generate coordinatively unsaturated Fe sites and enable rational tuning of Fe−N bonding. Combined density functional theory and ab initio molecular dynamics simulations reveal that the Fe−N bond acts as a dual-functional site, where the N atom facilitates H 2 O activation and proton transfer, while the Fe center promotes *CO + *CHO coupling toward C 2 intermediates. In contrast, defective MOFs with reduced Fe−N coordination form Fe−O sites that exhibit inferior activity due to inefficient H 2 O activation. Notably, the intrinsic flexibility of the Fe−N bond lowers the kinetic barrier for H 2 O dissociation. Consequently, the catalyst achieves a C 2 H 4 production rate of 24.5 μmol g −1 h −1 with an 87.1% electron-based selectivity, outperforming analogous systems. This work provides a blueprint for designing dual-functional sites in MOFs for solar-driven C 2 H 4 synthesis.

Glioblastoma (GBM) remains one of the most lethal intracranial malignancies due to its diffuse invasiveness and inevitable recurrence. Sonodynamic therapy (SDT) offers a noninvasive strategy for deep-tissue tumor ablation; however, its efficacy is often limited by rapid electron–hole recombination in conventional sonosensitizers, resulting in insufficient reactive oxygen species (ROS). In this study, a biomimetic nanosonosensitizer is rationally engineered via synergistic type II heterojunction interface construction and Cu─N coordination electronic activation. By anchoring Cu─N coordinated carbon dots (Cu-CDs) onto two-dimensional (2D) nanosheets, the compact heterojunction enables spatial charge separation, while Cu─N motifs act as kinetic promoters to accelerate interfacial electron transfer. This co-engineering strategy markedly enhances ultrasound (US) -triggered multi-ROS generation, leading to amplified oxidative stress. Biologically, intracellular copper overload triggers cuproptosis via lipoylated protein aggregation, whereas ROS burst induces PANoptosis-like cell death. Importantly, the synergistic death programs promote robust immunogenic cell death (ICD) with elevated Damage-associated molecular patterns (DAMPs) release/exposur, thereby activating antitumor immunity and contributing to enhanced therapeutic efficacy against GBM. This work provides new insights into the rational design of highly efficient sonosensitizers and offers new dimensions for precision SDT-based glioma sono-immunotherapy.

In eukaryotes, with the exception of mammals, trehalose fulfills multiple biological functions, including energy provision and stress tolerance. Trehalose-6-phosphate phosphatase (TPP) is a key enzyme in the trehalose biosynthetic pathway, rather than a trehalose synthase per se. Loss of TPP function or knockdown of its expression impairs trehalose synthesis, which in turn leads to developmental abnormalities or lethality in nematodes. These observations suggest that TPP represents a potential target for the development of anti-parasitic therapeutics. This study focused on the cloning, expression, and characterization of Trichinella spiralis TPP (TsTPP). A recombinant plasmid was constructed to express and purify the recombinant TsTPP protein (rTsTPP), whose immunogenicity was confirmed using positive serum from Trichinella spiralis ( T. spiralis )-infected mouse. The expression of TsTPP at different developmental stages of T. spiralis was determined by immunofluorescence assay. The specific TPP inhibitor N-(phenylthio) phthalimide (NPP) was employed to evaluate its lethal effect on T. spiralis muscle larvae (ML) in vitro. Furthermore, molecular methods such as qPCR and Western blot were used to detect the transcription and protein expression levels of TsTPP upon NPP treatment, aiming to identify new drug targets against T. spiralis . We successfully constructed the recombinant plasmid and obtained rTsTPP. Positive serum assays demonstrated the immunogenicity of rTsTPP, and we used indirect immunofluorescence assay (IFA) to determine its localization across different developmental stages of T. spiralis . Distinct distribution patterns were observed: TsTPP was diffusely distributed throughout the body of newborn larvae (NBL), accumulated in the intestinal glands, midgut ampulla and genital primordia of muscle larvae (ML), and localized to the mid and posterior intestine of adult worms (AW). To verify the lethal effect of NPP in vitro, we treated ML with NPP at concentrations of 12.5, 25, 50, 100, and 200 µg/mL for 24, 36, and 48 h, and evaluated its lethal effect by statistical analysis of worm morphology. The experimental results showed that the mortality rate of ML gradually increased with increasing NPP concentration and culture time. When the concentration was 200 µg/mL, the survival rate of ML was less than 50%. Furthermore, when treated with NPP at concentrations of 12.5, 25, 50, 100, and 200 µg/mL for 24 h, the transcription levels of the TsTPP gene decreased by 19%, 23%, 30%, 38% (all p < 0.05), and 57% ( p < 0.01), respectively; after 36 h of treatment, the transcription levels of TsTPP gene were reduced by 18% ( p < 0.05), 23%, 35%, 39%, and 60% (all p < 0.01); after 48 h of treatment, the transcription levels of TsTPP gene decreased by 19%, 23%, 42%, 42%, and 65% (all p < 0.01), respectively. N-(phenylthio) phthalimide (NPP) exhibits significant lethal activity against T. spiralis by inhibiting the trehalose synthesis pathway, providing basic data for future NPP as a new clinical drug target.

The direct integration of solar energy into zinc-air batteries (ZABs) provides a promising strategy for developing sustainable and high-performance energy storage systems. However, designing light-enhanced ZABs with efficient solar-energy utilization remains a significant scientific challenge. To address this challenge, a nitrogen-doped carbon/graphitic carbon nitride (N-C/g-C 3 N 4 ) composite photoelectrocatalyst was fabricated through mechanical ball-milling. Mechanical ball-milling enabled intimate interfacial coupling between N C and g-C 3 N 4 , thereby inducing interfacial electronic redistribution and facilitating charge transfer. Photoelectrochemical characterization, together with VB-XPS analysis, suggests that the N-C/g-C 3 N 4 interface promotes photogenerated electron transfer from g-C 3 N 4 to the conductive N C network while improving the utilization of photogenerated carriers. When used as the air cathode for ZABs, the composite exhibited strong bifunctional catalytic activity under illumination. Specifically, it exhibited an oxygen reduction reaction (ORR) half-wave potential (E 1/2 ) of 0.90 V and an oxygen evolution reaction (OER) overpotential of 501 mV. As a result, the assembled zinc-air battery (ZAB) achieved an open-circuit voltage (OCV) of 1.50 V, a peak power density of 572.9 mW cm −2 , a specific capacity of 720 mAh g −1 , and stable cycling for over 700 h. These results demonstrate the potential of interface-engineered dual‑carbon-based photoelectrocatalysts for high-efficiency solar-assisted metal-air batteries. Compared with N-C-based zinc-air battery (ZAB) and commercial Pt/C-IrO 2 -based ZAB, the light-enhanced N-C/g-C 3 N 4 -based ZAB exhibit improved photogenerated carrier utilization and facilitated interfacial charge transfer under illumination. These advantages lead to a significant performance enhancement, including an open-circuit voltage of 1.50 V, a peak power density of 572.9 mW cm −2 and ultra-stable charge-discharge cycling for over 700 h.

Following modification with APTES, the -NH 2 density reached to 12.04 groups/nm 2 . • Immobilized enzymes showed enhanced stability and broadened optimal reaction range. • Immobilization of LNB synthase by SNPs-NH₂ exhibited positive catalytic modulation. • After 7 cycles, the activity retention rate of the immobilized enzymes was 74–85%. • During 7 cycles of LNB synthesis, the LNB yield was maintained above 90%. Lacto-N-biose (LNB) is the core structural unit of human milk oligosaccharides and plays an indispensable role in the growth and development of infants. In this study, amino-modified SiO 2 nanoparticles (SNPs-NH 2 ) were used as carriers to immobilize sucrose phosphorylase (SPase), UDP-galactose-4′-epimerase (GalE), galactose-1-phosphate uridylyltransferase (GalT), and lacto-N-biose phosphorylase (LNBP), and LNB was synthesized in a one-pot method with high efficiency. The results showed that after activation of SNPs for 16 h at 25 °C with 2 mol/L hydrochloric acid, and modification with 3-Aminopropyltrimethoxysilane (APTES)/SNPs (2:1, v /m) at 65 °C for 9 h, the interface -NH 2 grafting density reached to 12.04 groups/nm 2 . Under the optimal immobilization conditions, the SPase, GalE, GalT, and LNBP were all well-loaded onto the carriers. At the same time, the temperature and pH stability of the enzymes were significantly improved, and the optimal reaction range was significantly expanded. The enzyme activity retention rate after 7 cycles of reaction was 74% to 85%, with the LNB synthesis yield rate remaining above 90%. This study effectively simplified the separation of enzymes from the reaction system during LNB synthesis and improved its stability, laying a foundation for the industrial production of LNB.
