Singlet oxygen ( 1 O 2 ) is a key reactive species in environmental, chemical, and biological systems. For decades, furfuryl alcohol (FFA) has been used as a probe for quantifying 1 O 2 based on the assumption that it reacts selectively with 1 O 2 but is inert toward other oxidants. However, we demonstrate that this assumption is fundamentally flawed in the chlorine-hydrogen peroxide (H 2 O 2 ) system-one of the most common contexts for 1 O 2 generation. Results demonstrate that chlorine alone can degrade FFA significantly, implying that previous studies may have systematically overestimated 1 O 2 yields. Specifically, raising pH facilitated the decay of chlorine but hindered FFA degradation, suggesting that 1 O 2 formation is unfavorable under alkaline conditions. Increasing the dosage of chlorine enhanced FFA degradation, but decreased the relative contribution of 1 O 2 to FFA degradation. More strangely, increasing the FFA dosage unexpectedly reduced the kinetics of FFA degradation, implying that the concentration of 1 O 2 was not constant under fixed chlorine-H 2 O 2 condition. Maintaining low dissolved oxygen enhanced FFA decay, suggesting that superoxide is not an intermediate for 1 O 2 formation. Furthermore, pyranone was not formed during FFA degradation processes, invalidating it as a characteristic product. These evidences together challenge the accountability regarding FFA selectivity, pyranone formation, and 1 O 2 formation mechanisms before using FFA for 1 O 2 quantification in chlorine-involved systems.

Fermentation by lactic acid bacteria (LAB) has been shown to boost health benefits and enhance flavor. This study investigated the impact of Limosilactobacillus fermentum HNU022, Pediococcus acidilactici HNU323 and Limosilactobacillus fermentum HNU054 fermentation on Portulaca oleracea juice (POJ). The result revealed fermentation boosted organic acids, antioxidant activities, and xanthine oxidase (XOD) inhibitory activity. The study using non-targeted metabolomics found 823 metabolites with differences, primarily concentrated in 5 pathways. Among them, isoflavonoid-related metabolites were upregulated, while purine metabolites were downregulated. The molecular docking results indicated that strong interactions between key metabolites and XOD. Electronic-tongue analysis showed improved flavor richness and reduced saltiness. In summary, lactic acid fermentation enhances the nutritional value, bioactivity, and flavor characteristics of POJ. Although molecular docking and in vitro activity assays indicate its antioxidant effects and XOD inhibitory capacity, these data still have certain limitations before in vivo activity studies are conducted for validation.

Enrichment and detection of trace antibiotics in complex matrices are challenged by severe matrix interference and low analyte abundance. Herein, a synergistic recognition interface was engineered on magnetic imprinted polymers by integrating acryloyl-calix[4]arene (AC[4]A) and aptamer (Apt). This dual-receptor interface exploits complementary binding modes to specifically recognize enrofloxacin (ENR). Specifically, AC[4]A captures the hydrophobic moiety of ENR via host-guest inclusion, while the aptamer targets its aromatic/carboxyl groups through hydrogen bonding and π-π stacking. Multimodal analyses ( 1 H NMR, CD, molecular docking, and MD simulations) reveal spatially distinct binding sites. Molecular docking indicates a synergistic enhancement of −2.9 kcal/mol in the ternary complex relative to binary sums, while MD simulations reveal that the cooperativity arises from entropy-driven conformational adaptation and interface complementarity. Moreover, the imprinted framework stabilizes the aptamer, retaining >80% extraction capacity after DNase I treatment. With an imprinting factor (IF) of 8.5 and a synergistic recognition factor (SRF) of 1.5, this dual-receptor interface demonstrates a clear “1 + 1>2” effect and the resulting method offers a wide linear range (2.5-300 μg/L) with a low detection limit (0.42 μg/L), well below regulatory limits. Applied to the enrichment and analysis of animal-derived samples, it significantly reduces matrix interference with recoveries of 83.3-98.2%. This dual-receptor strategy provides a reliable and sensitive platform for trace antibiotic enrichment and detection in complex matrices.

The rapid development of artificial intelligence and next-generation high-frequency communication technologies has increased the demand for electromagnetic (EM) wave-absorbing materials capable of operating under complex environments while maintaining multiple functionalities. In this work, hierarchically porous carbon was prepared using Ganoderma as a natural precursor through carbonization, activation, and heat treatment. The obtained carbon framework inherits the intrinsic biological channels of the Ganoderma scaffold, forming an interconnected porous structure composed of longitudinal macropores and abundant meso/micropores. The optimized GA-800 (heat-treated at 800 °C) sample exhibits efficient microwave absorption performance at a filler loading of 20 wt%, with a minimum reflection loss (RL min ) of −39.6 dB at a thickness of 1.55 mm and a maximum effective absorption bandwidth (EAB) of 5.7 GHz at 1.50 mm. Radar cross-section (RCS) simulations further demonstrate significant scattering suppression. In addition to microwave attenuation, the hierarchically porous carbon also displays hydrophobic behavior (contact angle of 127.5°), thermal insulation capability, and a stable photothermal response. These multifunctional properties originate from the biologically inherited hierarchical porous architecture, which simultaneously regulates EM wave propagation, thermal transport, and surface hydrophobic behavior. This study demonstrates that natural biomass structures can serve as effective templates for constructing lightweight multifunctional EM materials.

The development of sustainable and cost-effective thermal insulation materials is essential for improving energy efficiency and reducing dependence on petroleum-derived foams. Herein, a simple heating curing strategy was developed to fabricate bio-based closed-cell foams through hydroxypropyl methylcellulose (HPMC)-regulated Pickering emulsion templating. In this process, acrylated epoxidized soybean oil (AESO)-based emulsions were directly cured by heating, while the thermogelation and film-forming behavior of HPMC regulated the evolution of the porous structure. Increasing the HPMC concentration significantly enhanced the rheological stability of the emulsions, with the storage modulus increasing and the thermal gelation temperature decreasing from 66.1 °C to 40.3 °C. The foams exhibited low thermal conductivity of 0.042 − 0.058 W/m·K and exhibited pronounced thermal insulation in infrared thermography analysis. Meanwhile, the Young’s modulus increased from 2.64 MPa to 4.72 MPa, indicating improved mechanical properties. Micro-CT and SEM analyses revealed that the pore structure could be regulated by HPMC, with the average pore diameter increasing from 0.27 ± 0.13 mm to 1.26 ± 0.25 mm and the macropore volume fraction within the reconstructed region of interest decreasing from 84.4 % to 58.8 %. These findings provide a scalable and sustainable strategy for designing candidate bio-based thermal insulation foams, with potential relevance to energy-saving applications such as building-related insulation fillers, cold-chain logistics, and protective packaging.

New Delhi metallo-β-lactamase (NDM)-producing drug-resistant bacteria often form stubborn biofilms and cause severe pneumonia, resulting in conventional antibiotic failure. In this study, we developed gelatin-genipin microspheres co-loaded with EDTA and meropenem (GEM) for targeted treatment of NDM pneumonia. EDTA exerted dual functions: it chelated Zn 2+ to inactivate NDM enzyme and restore meropenem activity (FIC = 0.046875), while also disrupting bacterial biofilms through chelation. GEM microspheres enable accelerated drug release in the artificial phlegm environment. In a mouse model of NDM pneumonia, GEM microspheres can enhance the recruitment of neutrophils and M1 cells at the early stage (12 h) through bacterial clearance, modulate the secretion of interferon-γ by CD8 + T cells and natural killer cells, and reshape the pulmonary immune microenvironment. Furthermore, GEM treatment reduced pathological pulmonary immune cell infiltration and excessive inflammation at late time points (days 3-7). Taken together, GEM microspheres integrate biofilm disruption, enzyme inhibition, synergistic bactericidal effects, and immunoregulation, representing a promising strategy against NDM drug-resistant bacterial pneumonia.

PPPQ exhibited a high theoretical specific capacity and strong electron-withdrawing ability. • PPPQ showed narrow band gap, low solubility and excellent stability in 3 M ZnSO 4 . • PPPQ electrode exhibited electrolyte wettability, which enabled the improvement of interface regulation. Aqueous zinc-ion batteries (AZIBs) have attracted considerable attention because of their high safety, low cost, and environmental compatibility. However, the practical application of organic cathode materials is still limited by high solubility, low electronic conductivity, and restricted theoretical capacity. Herein, a heteroatom-substitution strategy was proposed to regulate the molecular structure of phenazine-based cathodes by replacing benzene rings with pyridine groups and tuning the nitrogen-doping positions. Two phenazine-based pyridine isomers, pyrido[2,3- b ]pyrido[3′,2′:5,6]pyrazino[2,3- f ]pyrido[3′,2′:5,6]pyrazino[2,3- h ]quinoxaline (PPPQ) and pyrido[3,4- b ]pyrido[4′,3′:5,6]pyrazino[2,3- f ]pyrido[4′,3′:5,6]pyrazino[2,3- h ]quinoxaline (PQNI), were designed and synthesized. Theoretical calculations reveal that the introduction of pyridinic N atoms modulates the electron-cloud distribution, narrows the HOMO–LUMO gap, enhances electron delocalization, and creates a negatively charged molecular environment, thereby improving redox activity and interfacial stability. Compared with PQNI, the ortho-linked PPPQ exhibits stronger π-conjugation, more ordered π–π stacking, lower dissolution, and faster charge-transfer kinetics. As a result, the PPPQ cathode delivers a high specific capacity of 354 mAh g −1 at 0.1 A g −1 and maintains 95% capacity retention after 2000 cycles at 5 A g −1 . In situ/ex situ characterizations and density functional theory calculations further demonstrate that the C N sites serve as redox-active centers and that PPPQ undergoes a proton-dominated three-step 6e − charge-storage process. This work clarifies the structure–property relationship of heteroatom-substituted phenazine-based organic cathodes and provides a molecular design strategy for high-performance AZIBs.

Composite PCMs use a graft semi-interpenetrating polymer network and short-cut carbon fibers. • The cross-linked network ensures excellent form stability and boosts mechanical properties. • High thermal energy storage capacity is maintained alongside the enhanced mechanical strength. • The g-IPN-PCM effectively suppresses battery temperature rise during charge-discharge cycles. • Adding short-cut carbon fibers enhances thermal management and protection for battery modules. Phase change materials offer energy-saving and uniform temperature control in lithium-ion battery thermal management. Enhancing the mechanical properties of phase change materials enables them to serve as structural protection against impact or accidental damage to batteries. In this work, a composite phase change material with a graft semi-interpenetrating polymer network is developed via a one-step in situ polymerization strategy, in which the polyurethane phase served as the thermal energy storage component and the acrylic copolymer phase provided structural reinforcement. The influence of polyethylene glycol molecular weight on the thermal and mechanical properties of the composite phase change material is investigated, and polyethylene glycol with a molecular weight of 6000 is identified as the optimal matrix component. The resulting g-IPN-PU6000 exhibited a high latent heat of 52.46 J/g and a tensile strength of 13.76 MPa. To further enhance mechanical robustness and interfacial stability, acid-treated short carbon fibers were incorporated into the g-IPN-PU6000 matrix. With 15 wt% acid-treated short carbon fibers, the composite phase change material achieved a tensile strength of 25.04 MPa and an impact strength of 4.31 kJ/m 2 , while maintaining latent heat values in the range of 51.73–70.32 J/g and a phase transition temperature between 52.51 and 57.93 °C. Numerical simulations demonstrated that IPN/ASCF CPCMs could maintain safe battery module temperatures under multiple 1C 2C charge-discharge cycles in various ambient conditions. Experimental results showed that under 3C discharge, the IPN/ASCF CPCM reduced battery temperature rise by 2.2 °C and mitigated battery damage by 45% during drop-ball impact tests. By integrating high latent heat with enhanced mechanical strength, the proposed multifunctional material has great potential to simultaneously perform thermal management and structural protection functions in battery systems.

LC sensing platform based on WGM laser is developed for the AD-related biomarker Aβ42 detection. • The sensor sensitivity is approximately 0.003 nm/pg/mL, and the LOD is 3 pg/mL. • RNA aptamer is used as recognition probes to enhance the specificity of the biosensing platform. • The combination of RNA aptamer and Aβ42 causes RI changes, resulting in WGM spectral shifts. • The structure design provides an ideal sensing platform for detecting biomedical samples. Alzheimer's disease (AD) is an irreversible and progressively worsening neurodegenerative disorder. Amyloid beta (Aβ42) plays a crucial role in the early diagnosis of this disease. However, the concentration of Aβ42 in the blood is extremely low, which poses a challenge for Aβ42 detection. Herein, a liquid crystal (LC) biosensing platform based on whispering gallery mode (WGM) laser was developed for rapid and real-time monitoring of the AD-related biomarker Aβ42. The LC microcavities were functionally modified using cetyltrimethyl ammonium bromide (CTAB) and RNA aptamers. Based on this, the quantitative monitoring mechanism of Aβ42 was analyzed, stemming from the interaction between the negatively charged RNA aptamer and CTAB, leading to the reorientation of LC molecules. This alters the refractive index distribution within the microcavity, thereby enabling the shift of the WGM spectrum. The dynamic changes of molecular orientation in the LC microcavity were monitored by polarization optical microscopy and spectral analysis. The experimental results showed that the total shifts in the resonance spectrum were directly proportional to the concentration of Aβ42 within the range of 0–1000 pg/mL. The sensitivity of the sensor is 0.003 nm/pg/mL. The experiment further confirmed the practicability of this sensor in the mouse serum. The sensor is inexpensive, easy to manufacture and fast and it is potentially useful for AD-related biomarker screening after further validation.

Isotropic wrinkles guide the crack formation in MXene/PDMS via a “peak pinning” effect. • The maze-like crack network provides high sensitivity (518.7) and a broad linear range (62.2%). • The sensor can monitor a full spectrum of human activities, from subtle pulses to vigorous body movements. • Machine learning enables the sensor to achieve 95.0% accuracy in complex gesture recognition. Simultaneously integrating high sensitivity, a wide linear range, and robust cyclic stability into a single flexible strain sensor remains a critical yet unresolved challenge for wearable electronics. Herein, we report a facile and scalable strategy to fabricate a MXene/PDMS sensor that employs isotropic wrinkle microstructures to guide the formation of a maze-like crack network (MCN). A critical “peak pinning” effect induced by these wrinkles effectively suppresses catastrophic crack propagation while promoting the progressive generation of the MCN, which inherits the meandering characteristics of the wrinkles. By precisely tuning the MXene deposition density (0.5–4 g m −2 ), both the wrinkle and crack geometry as well as the resultant piezoresistive properties can be tailored. Consequently, the optimized sensor achieves an exceptional balance of performance metrics: a high gauge factor of 518.7, a broad linear working range of 62.2%, fast response and recovery times (13 ms and 42 ms, respectively), and robust durability exceeding 1000 cycles. The device demonstrates versatile monitoring capabilities across a full spectrum of human activities, spanning subtle physiological signals (e.g., arterial pulse waves and laryngeal vibrations) to large-amplitude joint movements. Furthermore, when integrated with an XGBoost ensemble machine learning algorithm, the sensor enables a smart sensing system that achieves 95.0% classification accuracy for complex hand gestures. Collectively, this work presents a synergistic approach combining scalable fabrication, engineered microstructures, and artificial intelligence (AI)-enhanced data processing to advance the development of next-generation human-machine interfaces.

An instant dissolving W/O polymer prepared via reverse-phase emulsion polymerization. • An ultra-high acid resistance polymer formed from water-soluble hydrophobic monomers. • Integrated application for drag reducing and acidic thickening. • Quantum chemistry is used to clarify the mechanisms of dissolution and acid tolerance. Despite the considerable potential of multistage alternating acid fracturing Technique for unconventional tight reservoir stimulation, the integration of acid-thickening and drag-reduction functions within a single additive remains challenging due to the slow dissolution of gelling agents, poor acid resistance of drag reducers, and compatibility issues among multiple chemical additives. Herein, a multifunctional polymer emulsion (PAADT) was rationally designed using a hydrophobic monomer (AT-100) and a high-charge-density symmetric cationic monomer (Dimethyl Diallyl Ammonium Chloride, DMDAAC) to overcome these limitations. PAADT completely dissolved in water and concentrated HCl within 120 s and 330 s, respectively, while retaining viscosity stability for over 120 h and demonstrating exceptional tolerance to multivalent ions. Quantum chemical calculations, including LogP, independent gradient model based on Hirshfeld partition (IGMH), and electrostatic potential (ESP) analysis, revealed that the synergistic effect of polymer-water interactions and electrostatic repulsion governs the dissolution behavior and acid-salt resistance of PAADT. This work establishes a structure–property relationship between monomer architecture and macroscopic performance, providing a molecular design strategy for developing multifunctional polymers for complex environments.

A composite gel microsphere with a three-dimensional porous network structure has been developed: AO/SA-GQDs. • Under the same adsorption conditions, the introduction of GQDs increased the uranium adsorption capacity of the material from 52.584 mg·g −1 to 186.996 mg·g −1 . • AO/SA-GQDs composite gel microspheres exhibited a rapid U(VI) adsorption rate, reaching adsorption equilibrium within 300 min. • The highest experimental U(VI) adsorption capacity reached 231.593 mg·g −1 at 298.15 K and pH 5. • After five cycles, AO/SA-GQDs retained 84.99% of its initial adsorption capacity, with desorption rate above 80%. • The material is easy to prepare, and its raw materials are readily available and inexpensive, suggesting its potential for practical application. Stable uranium supply is essential for the development of nuclear power, and uranium extraction from seawater is regarded as a promising strategy for the sustainable development of nuclear energy. In this study, amidoxime-functionalized sodium alginate/graphene quantum dot composite gel microspheres (AO/SA-GQDs) were prepared via an in situ composite droplet-ion cross-linking method. Sodium alginate served as the matrix, amidoxime groups were introduced as U(VI)-specific binding sites, and graphene quantum dots (GQDs) were incorporated to regulate the pore structure and hydrophilicity of the microspheres. The AO/SA-GQDs microspheres exhibited a porous network structure, with a BET specific surface area of 42.997 m 2 ∙g −1 . Batch adsorption experiments showed that the optimal adsorption pH was 5. Adsorption kinetic analysis demonstrated that the AO/SA-GQDs microspheres reached adsorption equilibrium within 300 min, indicating a rapid U(VI) adsorption rate. At 298.15 K and pH 5, the highest experimentally measured equilibrium adsorption capacity was 231.593 mg∙g −1 , whereas the Langmuir-fitted maximum monolayer adsorption capacity was 244.499 mg∙g −1 . In the presence of various coexisting ions, the microspheres still maintained a high adsorption capacity for U(VI), demonstrating good selectivity. After five adsorption-desorption cycles, the adsorption capacity remained at more than 84% of its initial value, and the desorption efficiency remained above 80%. These results indicate that AO/SA-GQDs composite gel microspheres possess favorable adsorption capacity, selectivity, and recyclability, suggesting their potential for uranium extraction from aqueous environments.
