Nanoplastic (NPs) pollution represents one of the most persistent environmental crises of our time, requiring breakthrough material technologies for effective remediation. In this study, we engineer a semi-flexible micro-nano structured N-modified cellulose nanofibers@layered double hydroxide (N-CNF@LDH) composite aerogel through a dynamic hydrogen bonding and coordination interactions to achieve efficient removal of NPs, in which the LDH nanoflower clusters are uniformly anchored on the nitrogen-modified cellulose honeycomb skeleton. Under the action of dynamic hydrogen bonds, the structure undergoes spontaneous reorganization at new equilibrium positions upon release of external force, leading to a reversible opening-closing motion within the floral clusters. This design enables ultrahigh NPs adsorption (3648 mg·g −1 ) through reversible inter-petal channel opening, while compression-triggered petal contraction achieves instantaneous release (96% within only 10 s), exhibiting a desorption kinetics rate nearly three orders of magnitude higher than conventional adsorbents. Besides, the dynamic network enables rapid structural reconstruction of N-CNF@LDH through H-bond assembly, maintaining 80.4% NPs capacity and 95.2% shape recovery after 100 cycles. Exhibiting outstanding NPs removal performance in various real-world water systems while remaining cost-effective, this material breaks through the fundamental capacity-regeneration compromise in environmental remediation.

Due to lower energy consumption, great separation performance, and simple operation process, membrane technology plays an important role in gas separation. However, separation membranes often face a trade-off between permeance and selectivity. For instance, the pure layered double hydroxide (LDH) or metal organic framework (MOF) membranes exhibit high gas permeance but suffer from low selectivity. However, conventional Pd membranes typically have a thickness exceeding 50 μm, resulting in high costs and limited permeance. This article develops a novel strategy to fabricate a CoAl LDH/zeolitic imidazolate framework (ZIF)-67 heterostructure on a polydopamine-modified substrate, following by the infiltration of Pd nanoparticles (Pd NPs) into the LDH/ZIF framework via magnetron sputtering, resulting in a well-integrated LDH/ZIF@Pd membrane for highly efficient H 2 /CH 4 separation. In this architecture, the LDH sheets not only create nanocorridors for gas permeation but also provide the nucleation sites for ZIF grains. The incorporated Pd NPs and LDH/ZIF network form a well-integrated heterostructure, which endows the LDH/ZIF@Pd hybrid membrane with exceptional comprehensive performance, achieving H 2 /CH 4 selectivity of 48.3 and ultrahigh H 2 permeance of 8.4 10 5 GPU (75°C, 1 bar). This result sets a new benchmark for membrane-based gas separation, demonstrating outstanding potential for advanced hydrogen purification and sustainable energy applications. Graphical A novel layered double hydroxide (LDH)/zeolitic imidazolate framework (ZIF)@Pd hybrid membrane is developed for H 2 /CH 4 separation by constructing LDH/ZIF heterostructure and infiltrating Pd nanoisland, which demonstrates a remarkable combination of excellent H 2 /CH 4 selectivity of 48.3 and ultrahigh H 2 permeance exceeding 8.4 10 5 GPU, achieving an order of magnitude improvement in separation performance, showing great potential for hydrogen purification and sustainable energy applications.

The development of environmentally friendly and effective flame retardants is critical for improving the fire safety of wood materials. In this study, a bio-based flame retardant system composed of sodium lignosulfonate, chitosan, and ammonium polyphosphate was incorporated into a melamine-modified urea–formaldehyde resin to enhance the flame retardancy of wood surfaces. Combustion behavior was evaluated using cone calorimetry. Compared to untreated wood, the treated samples exhibited a 78.89% reduction in peak heat release rate, a 68.68% decrease in total heat release, and a 75.32% reduction in the flame growth index. The synergistic action of carbon-, nitrogen-, and phosphorus-containing components promoted the formation of a dense char layer, effectively suppressing oxygen ingress and heat release during combustion. This work demonstrates a sustainable and efficient strategy for improving the thermal stability and fire resistance of wood via resin-based surface modification and offers theoretical insights for the design of high-performance flame retardant coatings. Graphical To simultaneously optimize the flame retardancy and mechanical performance of wood, a novel flame-retardant composite derived from ammonium polyphosphate was synthesized. This material capitalizes on the synergistic effects between ammonium polyphosphate, lignin, and chitosan, thereby constructing a robust and efficient flame-retardant architecture. Subsequently, the resultant composite flame retardant was incorporated into melamine-urea-formaldehyde resin via blending and crosslinking, affording a three-dimensionally networked macromolecular resin with integrated flame-retardant functionality.

2,5-Bis(hydroxymethyl)furan (BHMF) is a promising intermediate for the synthesis of pharmaceuticals and crown ethers, whereas achieving a high reaction rate in the hydrogenation of 5-hydroxymethylfurfural (5-HMF) to form BHMF remains challenge. In this work, a series of Cu/CeO 2 –x catalysts ( x denotes H, Air, Ar) were synthesized by calcination under different atmospheres (10% H 2 /Ar, Air, Ar) and evaluated for the 5-HMF hydrogenation to BHMF. Cu/CeO 2 –Ar exhibited a superior reaction rate of 26.8 mmol·g cat −1 ·h −1 and BHMF yield of 99.1% under the condition (180°C, 5 h, 1 MPa H 2 ), significantly outperforming Cu/CeO 2 –H and Cu/CeO 2 –Air. The characterizations reveal that the calcination in the oxygen-deficient argon atmosphere led to high Cu dispersion and minimized Cu particle size in the Cu/CeO 2 –Ar. These properties resulted in the abundant Cu + –O V –Ce 3+ sites and increased Cu 0 number. In situ Fourier transform infrared spectroscopy analysis elucidates the distinct roles of these active sites. Cu + sites are responsible for perpendicular adsorption of the 5-HMF carbonyl group, and Cu 0 sites drive efficient H 2 dissociation. In contrast, the O V –Ce 3+ sites do not adsorb 5-HMF and H 2 . The close synergy between numerous Cu 0 sites and abundant Cu + sites in the Cu/CeO 2 –Ar accelerates the process of 5-HMF hydrogenation to BHMF. Graphical The oxygen-deficient argon atmosphere led to high dispersion and small particle size of Cu in Cu/CeO 2 –Ar. These properties resulted in the abundant Cu + sites for the adsorption of CO from 5-HMF and the numerous Cu 0 sites to efficiently dissociate H 2 , synergistically boosting catalytic reaction rate to 26.8 mmol·g cat -1 ·h -1 .

Incorporating two-dimensional (2D) perovskite phases at the interfaces of three-dimensional (3D) perovskite solar cells improves device performance. These 2D structures form in the bulk and at interfaces of the perovskite film by adding long-chain ammonium salts into the perovskite, but achieving them exclusively at the buried interface remains challenging. Here we sequentially graft thioglycolic acid and oleylamine onto SnO 2 nanoparticles. The strong chemical bond between thioglycolic acid and oleylamine ensures that cation exchange with formamidinium iodide, a perovskite precursor, occurs only during thermal annealing, creating a 2D/3D perovskite structure solely at the bottom interface. This localized 2D layer accelerates 3D phase formation, enhances perovskite crystallization and reduces defect concentration at the interface by over tenfold. The resulting solar cells achieve power conversion efficiencies of 26.19% (certified 26.04%, 0.09 cm 2 ), 23.44% (aperture area of 21.54 cm 2 , certified 22.68%) and 22.22% (aperture area of 64.80 cm 2 ), respectively.

The development of efficient and stable photocatalysts for hydrogen evolution is crucial for solar-to-fuel conversion. Here, we report Cu-porphyrin (CuTCPP)/oxygen-doped g-C 3 N 4 (O–CN) nanohybrids as high-performance sonophotocatalysts, where strong π–π stacking interactions create robust heterojunctions that promote efficient charge separation and transfer. The optimal 2 % CuTCPP/O–CN2 sample exhibited a 3.3-fold enhancement in H 2 evolution compared to O–CN2 under simulated light coupled with ultrasonication. Experimental results combined with density functional theory (DFT) calculations confirmed the suppression of charge recombination and highlighted the synergistic contribution of ultrasonic excitation with light irradiation. Furthermore, oxygen doping was found to not only reinforce the CuTCPP/O–CN interface but also provides robust anchoring sites for Pt cocatalysts, preventing leaching and aggregation while electronically modulating Pt to optimize its d-band center and H 2 adsorption free energy. These findings provide valuable insights into the rational design of stable and high-active hybrid photocatalysts for solar fuel generation.

Cancer remains a global health challenge, calling for integrated strategies that combine precise diagnosis with synergistic treatment. Although glucose oxidase (GOx)-mediated starvation therapy disrupts tumor metabolism by converting glucose into cytotoxic hydrogen peroxide (H 2 O 2 ), its clinical translation is hindered by inefficient delivery and insufficient monotherapy efficacy. To address these issues, we developed a multifunctional nanoplatform by encapsulating GOx within hollow porous superparamagnetic Fe 3 O 4 nanoparticles (Fe 3 O 4 -GOx NPs) to preserve its catalytic activity and enable high loading capacity. This system simultaneously enables magnetic resonance imaging (MRI), photothermal therapy, and enzyme-mediated catalytic intervention. In vitro studies demonstrated strong T 2 -weighted MRI contrast for precise tumor localization, together with near-infrared laser-triggered hyperthermia that enhance the efficacy of GOx-mediated starvation therapy, elevating oxidative stress and promoting apoptosis in 4T1 cells. In 4T1 tumor-bearing mice, a single administration of Fe 3 O 4 -GOx NPs combined with laser irradiation elicited potent tumor suppression through the synergistic effects of intratumoral ROS generation, glucose depletion, and localized photothermal ablation, outperforming either modality alone. Histopathological assessment revealed negligible systemic toxicity and preserved organ integrity. This work presents an integrated theranostic nanoplatform that unites tumor-targeted imaging, enzyme- driven metabolism intervention, and photothermal therapy into a single system, offering a promising strategy for precision cancer management.

Ferrate(VI) (Fe(VI)) is a powerful oxidant for wastewater treatment, but its use is hindered by electron transfer limitations. To address this, we designed a NiFe-layered double hydroxide-carbon nanotube (NiFe-LDH-CNT) hybrid photocatalyst. The design is based on the hypothesis that incorporating conductive CNTs can enhance interfacial charge-transfer capability, thereby promote Fe(VI) activation. Under visible light, this catalyst enhances Fe(VI) performance by facilitating the formation of reactive high-valent iron intermediates, accompanied by the generation of reactive oxygen species. Compared with pristine NiFe-LDH, the CNT-integrated composite exhibits improved charge separation and accelerated interfacial electron transport, resulting in enhanced pollutant degradation efficiency. In addition, the catalyst remains stable and effective over time, even in complex water environments. This approach offers a practical way to enhance Fe(VI)-based water treatment processes.

Wearable solar-blind photodetectors (SBPDs) are critical for health and environmental monitoring. However, achieving real-time visual feedback while maintaining high sensitivity and flexibility has been a great challenge. Here, we present a cutting-edge visualized fiber-shaped SBPD (VFSBPD) that synergistically integrates electronic and optical detection modes for wearable-compatible solar-blind ultraviolet (UV) monitoring. Our newly-developed VFSBPDs combines a solar-blind-sensitive semiconductor with a fluorescent carbon dot-modified gel electrolyte, achieving a remarkable responsivity of 2.3 mA W −1 and a rapid response time of 230 ms. Moreover, it provides a dual-mode output, including precise electronic quantification and instant colorimetric feedback, greatly enhancing both reliability and user interaction. The fiber-shaped architecture of VFSBPDs guarantees superior mechanical compliance, weavability, and omnidirectional luminescence, making it easily integrated into textiles. We have demonstrated the versatility of VFSBPDs in UV imaging, secure optical communication, and environmental monitoring. This work bridges the gap between high-performance detection and practical wearable applications, offering a highly versatile platform for dual-mode solar-blind UV sensing.

Aflatoxin B1 (AFB1), the most toxic mycotoxin among aflatoxin family, which presents a risk to food safety and human health at a trace level. Herein, the self-enhanced electrochemiluminescence (ECL) emitters of Au nanoclusters-anchored g-C 3 N 4 nanosheet (Au NCs@g-C 3 N 4 ) were synthesized, in which the Au NCs as a co-reaction accelerator enhanced the ECL stability and intensity. Integrating with CRISPR/Cas12a system, the Au NCs@g-C 3 N 4 behaved as sensing substrate to construct a “off-on” switch-type ECL sensor for AFB1 detection based on ECL resonance energy transfer (ECL-RET). The presence of targets AFB1 can specifically bind its aptamer to trigger the release of the activator. Using dual aptamer-regulated activation of CRISPR-Cas12a, AFB1 can be quantified via the ECL sensor, displaying a wide detection range from 0.2 pg/mL-100 ng/mL and a detection limit of 0.08 pg/mL. Furthermore, good practicability was verified in real samples assay, providing an efficient tool for the early warning of AFB1 pollution.

Hepatocellular carcinoma (HCC) is one of the most lethal malignancies worldwide, and early diagnosis is crucial. Golgi protein 73 (GP73) has emerged as a promising serum biomarker for HCC. However, current detection methods often fail to meet routine screening requirements due to limitations in sensitivity and operational simplicity. To address these challenges, we have developed a novel fluorescent aptamer-based sensor for highly sensitive GP73 detection based on the fluorescence resonance energy transfer (FRET) mechanism between graphitic carbon nitride quantum dots (g-CNQDs) and a copper-based metal–organic framework (Cu-TCPP). g-CNQDs were covalently conjugated with a GP73-specific aptamer to serve as the fluorescent donor, while two-dimensional Cu-TCPP nanosheets acted as the efficient acceptors. Fluorescence was quenched upon donor–acceptor interaction via FRET. In the presence of GP73, aptamer–target binding disrupted FRET interaction, separating the donor from the acceptor and restoring fluorescence in a concentration-dependent manner. Under optimal conditions, the sensor exhibited excellent linearity over a concentration range 1.0–225.0 ng mL⁻¹, with a detection limit as low as 0.907 ng mL⁻¹. Recoveries for spiked human serum samples ranged from 95.96% to 103.85%, with relative standard deviations (RSDs) of 0.38%–5.48%. The developed aptamer sensor demonstrated excellent sensitivity, selectivity, and stability, providing a powerful tool for early HCC diagnosis and offering strong potential for real-time analytical applications. Graphical A novel fluorescent aptamer sensor for GP73 detection by leveraging the fluorescence resonance energy transfer (FRET) mechanism between graphite-phase carbon nitride quantum dots (g-CNQDs) and a copper-based organic framework (Cu-TCPP). This platform achieved a good linear relationship with GP73 concentration in the range of 1.0–225.0 ng mL -1 for GP73 concentration, and a detection limit of 0.907 ng mL -1 .

The research aimed to elucidate the interaction and mechanism between the Portulaca oleracea L. extract (POE) and the pork myofibrillar proteins (MPs) from the perspectives of fluorescence spectroscopy and molecular docking. The results showed that POE significantly increased intermolecular hydrogen bonds and hydrophobic interactions in MPs ( P < 0.05). Among the non-covalent forces between POE and MPs, hydrophobic interactions were dominant followed by hydrogen bonds. POE would cause a decrease in the endogenous fluorescence intensity of MPs, and the quenching type was static quenching. The binding molar ratio of POE to MPs was 1:1, and the formed complex exhibited high stability. The thermodynamic constants ∆G < 0, ∆H > 0, and ∆S > 0 indicated that the binding process between POE and MPs was spontaneous, with hydrophobic interactions being the primary driving force. Additionally, the nine most abundant compounds in POE were selected for molecular docking with myosin, and the binding energies were all negative, confirming that POE could spontaneously interact with MPs. The molecular docking results further demonstrated that hydrophobic interactions and hydrogen bonding were the main binding forces, with Leu270 potentially serving as a key amino acid residue in the interaction between POE and MPs. This study provides valuable insights into the molecular interactions between Portulaca oleracea L. extract and pork myofibrillar proteins, offering a theoretical basis for phenolic small molecule substances in regulating protein oxidation and potential applications in improving meat product quality.
