The quality of yellowfin tuna is highly vulnerable to microbial proliferation, which accelerates quality deterioration and spoilage throughout storage. In this study, the dynamic changes in biogenic amines (BAs), total volatile basic nitrogen (TVB-N), and total plate count (TPC) across a different storage temperature range of 0 to 25 °C were studied, followed by a shelf-life prediction based on kinetic models. The TPC, TVB-N, and most BAs increased significantly with increasing storage time and temperature. Correlation analysis was used as an exploratory approach and showed that only histamine and cadaverine exhibited significantly positive correlations (|r| ≥ 0.6,p< 0.05) with TPC and TVB-N within the present dataset. Histamine was selected as a candidate BA indicator for kinetic modeling because only this BA changed significantly during storage at different temperatures. Utilizing histamine, TPC, and TVB-N, preliminary kinetic equations for shelf-life estimation were developed using first-order kinetics and the Arrhenius equation. Among the tested indicators, TPC showed relatively greater temperature sensitivity and preliminary within-batch agreement. These results provide preliminary reference data for further validation of tuna during the refrigeration process.

Fresh pork remains susceptible to psychrotrophic spoilage during superchilled storage. Although oregano essential oil (OEO), nisin, and active absorbent pads have each been studied, their effects on spoilage-community proliferation and concurrent quality loss remain poorly resolved. Here, we coupled longitudinal 16S rRNA gene profiling with conventional microbiological and quality measurements to evaluate a poly(vinyl alcohol)/soy protein isolate pad containing OEO-loaded soluble soybean polysaccharide-nisin nanoparticles (PS-NPs). Pork was stored at −1 °C for 24 days without a pad (CK), with a nanoparticle-free pad (PS), or with PS-NPs. Bacterial communities in CK and PS-NPs were profiled alongside total viable count, TVB-N, TBARS, protein carbonyls, color, water-holding capacity, and sensory quality. Compared with CK, PS-NPs slowed the increase in viable counts and delayed physicochemical and sensory deterioration. On day 24,Pseudomonasrelative abundance was 39.48% with PS-NPs and 51.02% in CK. TBARS and protein carbonyl contents were 36.96% and 19.44% lower than CK, respectively, while cooking loss was 28.49% versus 32.18%. Among the evaluated taxon-quality pairs,Pseudomonas psychrophilashowed the strongest positive association with protein carbonyl content. Unlike earlier performance-focused studies, this work links packaging-associated community shifts with concurrent chemical, physical, and sensory changes under superchilling. The findings support PS-NPs as a preservation strategy.

Early detection of Bactrocera dorsalis ( B. dorsalis ) infestation in citrus is challenging due to the asymptomatic nature of initial larval stages. Colorimetric sensor arrays (CSAs) are promising for non-destructive detection of B. dorsalis infestations in citrus, yet they still face limitations in reliably identifying the key volatile organic compounds (VOCs) released by infested citrus. In this study, we developed a MOF-enhanced colorimetric sensor array integrating pH-sensitive dyes into ZIF-7 nanoparticles for non-invasive detection. The array detected VOCs associated with early infestation, including D -limonene, decanal, and linalool, identified via GC-MS. The dye/ZIF-7 composite CSA exhibited enhanced sensitivity compared to the pure dye sensor array. Furthermore, across the 4-day test period, infested samples registered a progressive rise in total Euclidean distance (ED) of color change, reaching a 171.7-unit increase over healthy controls on day 4. To enhance the accuracy and efficiency of infestation detection, we implemented a machine-learning pipeline using Dung Beetle Optimizer (DBO) for feature selection and Tree-structured Parzen Estimator (TPE) for hyperparameter tuning. Consequently, the XGBoost classifier achieved a peak test accuracy of 97.15 %, enabling reliable detection during the early stage of infestation. Overall, this study offers a non-destructive and cost-effective approach for batch-mode early detection of B. dorsalis infestation in citrus, advancing the potential for enhanced postharvest monitoring and pest management strategies.

To address consumer concerns regarding exudate from fresh chicken, this study aims to develop an active food packaging material with excellent antibacterial properties, mechanical strength, and moisture management capabilities by preparing oxidized corn starch/polyvinyl alcohol/agarose (OST/PVA/AG) composite pads using oxidized corn starch (OST) as a functional enhancer. Fourier transform infrared spectroscopy and X-ray diffraction analyses confirmed that OST was successfully incorporated into the PVA/AG matrix through intermolecular hydrogen bonding and esterification cross-linking reactions. These interactions enhanced intermolecular forces and reduced the material's crystallinity. Microscopic morphology revealed that the composite pads exhibited a homogeneous porous structure, with thickness and color varying with increasing OST content. Performance tests indicated that the antibacterial efficacy against E. coli and S. aureus improved significantly in a dose-dependent manner as the OST content increased. Considering the overall performance, the composite pad containing 1% OST demonstrated optimal antibacterial effects (inhibition rate exceeding 99%), mechanical properties (tensile strength of 0.54 MPa, elongation at break of 72%), and water absorption capacity (4.5 g/g), with a cell viability of 85%, indicating good biocompatibility. Chicken preservation experiments further confirmed that the OST/PVA/AG-IV pad effectively absorbed exudate and inhibited microbial growth. After 6 days of storage, the total volatile basic nitrogen (TVB-N) value of the chicken was maintained at 14.81 mg/100 g, and the total viable count remained below the spoilage threshold, significantly extending the shelf life by approximately 1 day compared to the control group. These results confirm the promising application potential of OST/PVA/AG composite pads in the field of meat preservation.

With the growing emphasis on green chemistry and sustainable development, the resource utilization of waste salt has garnered significant attention. The production of soda ash from waste sodium sulfate presents a viable and sustainable pathway for the green transformation of the chemical industry. Current studies on this production method primarily focuses on single-factor effects on product purity, often overlooking the critical synergistic or antagonistic interactions between key process parameters. To address the aforementioned issues, this study systematically investigated the key factors and their interactions using response surface methodology. The process began with a pretreatment stage that effectively removed total organic carbon and color, while also adsorbing organic impurities such as heterocycles, anilines, ketones, phenols, and long-chain alkanes. For the soda ash synthesis via the double decomposition reaction of the pretreated waste sodium sulfate, single-factor experiments and response surface methodology optimization established the following optimal conditions: a reaction time of 1.96 h, a reaction temperature of 39 °C, and a material mass ratio of 1.284 (m (ammonium bicarbonate): m (sodium sulfate)). Under these conditions, the maximum soda ash purity of 99.35% was achieved. Furthermore, a binary regression model was developed for the process, with predictions showing excellent agreement with experimental data, confirming its reliability and practical utility. Additionally, the kinetics of the double decomposition reaction were determined by fitting a pseudo-second-order kinetic model in combination with the Arrhenius equation, and the resulting expression is as follows. 1 / t ln β 0 − X β 0 1 − X − β X / t = exp − 69475 / R T + 4.3637 × 10 − 16 . Through this waste-salt valorization pathway, not only can the accumulation of industrial waste sodium sulfate and associated environmental pollution risks be effectively reduced, the production cost per ton of sodium carbonate can be reduced by approximately 600 RMB, yielding significant sustainable economic benefits and providing strong support for advancing a green and low-carbon economy.

Goji berry juice (GBJ) is a highly popular healthy drink among consumers. Rapid monitoring of the antioxidant properties of GBJ is crucial and necessary. A colorimetric sensor array (CSA) based on composite dyes was used for the rapid detection of the antioxidant properties of GBJ. High-dimensional spectral fingerprint information combined with chemometric methods was used to construct a quantitative prediction model. The effects of different preprocessing and feature screening methods on model prediction were compared. Machine learning algorithms were used to establish quantitative prediction models. The CARS-PLSR model achieved accurate quantification of total phenol, with Rp and RPD values of 0.95 and 3.18, respectively. For DPPH free radical scavenging rate, the CARS-LSSVR model had an Rp value of 0.95, an RPD value of 3.33, and an RMSEP of 0.04.

An electrocatalytic Cu-GHM system with tunable nanoconfined spaces is constructed. • The electrified system enables 73%–100% degradation of 13 emerging contaminants. • 100 h of continuous operation is demonstrated without loss of structural integrity. • The electrified system also exhibits high energy efficiency (0.07 kWh/m 3 ). • DFT calculations and MD simulations elucidate the degradation mechanism. Persulfate-based advanced oxidation processes are promising for removing refractory contaminants from aquatic systems, however, their performance is often constrained by limited reactive oxygen species utilization and restricted mass transfer. Although spatial confinement engineering of electrocatalytic membranes has improved persulfate activation, the underlying structure–property–performance relationships remain insufficiently understood. Here, we report an electrochemical peroxomonosulfate activation system employing a three-dimensional graphene hydrogel-supported copper nanoparticle membrane (Cu-GHM) as the cathode. The system demonstrated broad applicability, achieving 73%–100% degradation across 13 representative emerging contaminants in real water matrices. Its long-term stability was further confirmed through a 100-h continuous operation test specifically using ranitidine as the model pollutant. By regulating pore architecture through controlled compression, the nanoconfined space was tuned from 13.5 to 5.0 nm, revealing a strong dependence of catalytic performance on confinement scale. The smallest pore size (5.0 nm) resulted in an 8.1-fold enhancement in degradation kinetics, attributed to increased local reactant concentration, improved mass transport, and facilitated interfacial electron transfer. Comprehensive spectroscopic analyses and molecular dynamics simulations elucidated the confinement-enhanced catalytic pathways and mass-transfer behavior. This study provides mechanistic insights into synergistic nanoconfinement and electric-field effects, offering a rational framework for designing energy-efficient electrified membrane systems for water treatment.

The accurate, simultaneous, and in situ monitoring of multiple sweat biomarkers holds great promise for both athletic performance optimization and disease management. Sweat biomarker monitoring using a wearable colorimetric sweat sensor provides a wireless, electronic-free, and battery-free strategy with easy integration with smart mobile devices such as smartphones. However, existing wearable colorimetric sweat sensors still suffer significantly from ambient light interference, sweat pH variation-induced detection errors, and the physiological variability of sweat rate. In this study, we introduce a smart wearable microfluidic colorimetric sensing system (SWSS) that overcomes these challenges by integrating a flexible epidermal patch with an AI-assisted cloud analytical pipeline. The disposable microfluidic patch enables passive sweat collection and features multiplexed colorimetric assays for chloride, pH, urea, and lactate, alongside a microfluidic channel for sweat rate tracking. Images acquired using a smartphone are uploaded and processed through a backend cloud system featuring an AI-powered data processing system. This system automatically corrects the errors caused by varying lighting conditions and varying sweat pH, thus improving detection accuracy significantly. In addition, this sensor system measures and calculates sweat rate from the dye front's displacement in the sweat rate channel, enabling a sweat rate normalization framework which enhances physiological interpretability. Experimental results demonstrate excellent agreement between predicted and true concentrations across all analytes (R 2 ≥ 0.994). The system further supports on-body testing and real-time analysis through seamless smartphone integration. These findings highlight SWSS platform as a promising next-generation platform for accurate and individualized sweat biomarker sensing for human physiological status monitoring.

Introduction: Invasive aspergillosis (IA) is a life-threatening disease in immunocompromised individuals, creating an urgent need for rapid, sensitive, and user-friendly methods for early detection of Aspergillus spores in clinical and environmental samples. Methods: In this study, we developed a rapid ultrasonication-based beads beating (USBB) method for cell lysis and fungal DNA release, along with an integrated magnetic beads-based direct amplification (MBDA) method utilizing microfluidic chip technology. Our flexible thin-film microfluidic chip was developed to enable immediate contacting with an ultrasonic oscillator for nucleic acid extraction. Results and discussion: The chip achieved a lysis efficiency of 85.5% for Aspergillus at 10 5 spores per sample. Magnetic beads releasing Fe ions at 75-860 ng/mL allowed high-efficiency direct PCR amplification. Complete transfer of the nucleic acid extract into PCR amplification led to a 100-fold improvement in detection sensitivity. The integrated USBB-MBDA system completed the entire workflow from sample-in to result-out within 35 min (5 min fungal DNA release and 30 min TaqMan assay). Using this approach, we achieved simultaneous triplex detection of Aspergillus fumigatus, Aspergillus flavus , and Aspergillus niger , with a sensitivity as low as 10 spores per test. Validation on 37 clinical samples showed complete concordance with MALDI-TOF mass spectrometry (MS). This study establishes an integrated nucleic acid extraction and magnetic bead–enabled direct amplification strategy, providing a versatile approach for the development of automated analytical platforms with broad applicability to in vitro diagnostics.

The development of sustainable and fire-safe thermal insulation materials is critical for enhancing building energy efficiency and safety. This study reports the fabrication of porous composites reinforced with fly ash-derived silica and nanocellulose/poly (vinyl alcohol) via directional freezing and vacuum-assisted impregnation. By adjusting the silicate modulus, the interfacial interactions and pore-wall reinforcement were controlled, resulting in improved mechanical strength, thermal resistance, and flame retardancy. The optimized composite exhibits a compressive strength of 22.6 MPa and achieves a UL-94 V-0 rating, indicating excellent structural stability and fire safety. Although its thermal conductivity (∼0.287 W/(m·K)) is higher than that of ultralight insulation materials, the composite provides moderate thermal resistance together with high mechanical robustness and improved fire safety, making it more suitable for fire-safe thermal barrier applications rather than ultralow-k insulation. Compared to conventional insulation materials, the developed composite demonstrates a balanced combination of mechanical robustness, thermal resistance, and fire protection. This work provides a sustainable strategy for converting industrial solid waste into multifunctional fire-safe thermal barrier materials and offers new insights into the design of multifunctional bio-based porous composites for sustainable construction.

MXene displays exceptional promise for water purification, owing to its versatile surface chemistry and favorable physicochemical properties. However, its separation performance is substantially hindered by intercalation-induced swelling. Here, inspired by the “brick-and-mortar” structure of nacre, nacre-like nanocomposite membranes are developed through the co-assembly of MXene nanosheets (bricks) and polyetherimide (mortar). Leveraging MXene's unique properties, polyetherimide serves three pivotal functions: it acts as "spacer", precisely defines the interlayer spacing at ∼13.84 Å; it functions as "regulator", abundant hydrophobic groups regulate the microenvironment within the nanochannels; and it serves as "stabilizer", establishes robust non-covalent interactions with the MXene basal planes, thereby reinforcing channel integrity. Consequently, the resulting membranes exhibit outstanding stability in aqueous media, achieving a swelling ratio as low as 1.56%. Remarkably, after 1080 h of static water immersion, the membrane retained a relatively stable interlayer structure and separation performance, demonstrating prolonged aqueous stability. This bioinspired strategy provides critical insights for the rational design of structurally stable two-dimensional membranes.

To address the limited activity and durability of oxygen evolution reaction (OER) electrocatalysts, we present an integrated in situ strategy for constructing a three-dimensional Ni-Co dendritic electrode matrix coupled with a surface amorphous Ni-Co-Fe layered double hydroxide (LDH) catalytic layer. A Ni-Co dendritic matrix (NCDEM) with enhanced electrolyte accessibility and mass transport properties is first fabricated via jet electrodeposition, followed by the in situ hydrothermal growth of Ni-Co-Fe LDH nanosheets to construct a Ni-Co-Fe dendritic electrode (NCFDE). The introduction of NaBO₂ during the hydrothermal process regulates surface etching kinetics and the Fe³ ⁺ coordination environment, promoting uniform nanosheet growth and triggering the crystalline-to-amorphous transition of the LDH structure. The amorphous LDH layer increases the accessible active surface area, facilitates the formation of reconstructed NiOOH active species during OER, and enhances structural stability during prolonged electrochemical operation. The optimized B2-NCFDE exhibits outstanding OER performance in 1 M KOH, requiring an overpotential of only 215.34 mV to achieve 100 mA cm⁻², with a Tafel slope of 38.29 mV dec⁻¹ and stable operation at 500 mA cm⁻² for 2000 h. Furthermore, the B2-NCFDE||B2-NCFDE electrolyzer achieves 100 mA cm⁻² at a cell voltage of 1.822 V and demonstrates excellent durability for overall water splitting. This work provides a scalable strategy that integrates electrode architecture engineering with amorphous LDH regulation for efficient and durable hydrogen production.
