Hydroquinone (HQ), a toxic and persistent pollutant, requires sensitive and reliable detection strategies beyond conventional chromatographic or electrochemical methods. Here, we report a nitrogen-doped 1T/2H-MoS 2 /Co 9 S 8 /CdS ternary nanozyme synthesized via a urea-mediated hydrothermal route. Urea acts as a bifunctional agent, simultaneously stabilizing the metastable 1T-MoS 2 phase and introducing sulfur vacancies through nitrogen substitution. This defect-phase engineering optimizes the electronic structure, as evidenced by a 0.2 eV positive shift in Mo 3d binding energy, and exposes coordinatively unsaturated Mo sites that accelerate hydroxyl radical (•OH) generation. Coupled with the redox activity of Co 9 S 8 and the adsorption capability of CdS, the composite exhibits markedly enhanced peroxidase-like activity, characterized by higher catalytic turnover and stronger H 2 O 2 affinity compared to undoped systems. A colorimetric sensor constructed from this platform enabled ultrasensitive HQ detection with a detection limit of 0.29 μM and excellent recoveries (100.18% to 101.64%) in spiked real water samples, while maintaining strong selectivity and operational stability. This work establishes a nitrogen-doping-driven paradigm for phase stabilization and defect regulation, offering a generalizable strategy for designing high-performance nanozymes for environmental monitoring.

The development of efficient and thermally stable near-infrared (NIR) phosphors is crucial for advancing next-generation smart NIR lighting sources, yet remains a formidable challenge. Herein, we report a high-performance K 2 NaAlF 6 :Mn 4+ ,Cr 3+ phosphor engineered via an efficient energy transfer strategy. The optimized phosphor exhibits a dominant NIR emission peak at 725 nm and achieves an exceptional energy transfer efficiency of 87.5 % from Mn 4+ to Cr 3+ . This efficient energy transfer, combined with the enhanced Cr 3+ absorption, contributes to a 91 % enhancement in NIR emission intensity and an increase in internal quantum efficiency from 74.0 % to 82.7 %. Meanwhile, the thermal stability is also significantly improved, with the co-doping sample retaining 83.4 % of its emission intensity at 425 K compared with 73.6 % for the singly Cr 3+ -doped counterpart, which is attributed to the enhanced lattice rigidity and the energy transfer process induced by Mn 4+ doping. A NIR phosphor-converted light-emitting diode (NIR pc-LED) fabricated with this phosphor and a blue chip demonstrates outstanding performance in applications of bioimaging, non-destructive testing and night vision imaging. Furthermore, its outstanding scintillation properties also enable high-resolution X-ray imaging. This work establishes a feasible design strategy for developing advanced multifunctional NIR luminescent materials that simultaneously achieve high efficiency and excellent thermal stability.

Efficient CO 2 capture is critical for mitigating climate change, and solid amine adsorbents have emerged as a promising solution. This study reports a sustainable strategy for developing high-performance solid amine adsorbents by valorizing coal gasification slag (CGS), an industrial waste byproduct, into hierarchical porous silica supports (X-SiO 2 ). A key innovation of this work lies in the use of weak-acid modulation (formic, acetic, and citric acids) to precisely tailor pore architecture. Among the resulting materials, the citric acid–modulated silica (CA-SiO 2 ) exhibits an exceptionally high specific surface area (447 m 2 /g) and pore volume (0.8 cm 3 /g), providing an optimal framework for uniform amine dispersion. To further enhance adsorption performance and overcome the stability limitations of conventional mono-amine systems, a mixed-amine strategy combining diethanolamine (DEA) and tetraethylenepentamine (TEPA) was introduced. Mechanistic investigations reveal that DEA suppresses TEPA aggregation through hydrogen-bonding interactions, thereby improving amine accessibility and CO 2 diffusion pathways. As a result, the optimized adsorbent (CA-30TEPA-30DEA) achieves a high CO 2 uptake of 5.07 mmol/g at 70 °C and retained 4.51 mmol/g after 20 adsorption–desorption cycles, representing a ∼ 10% enhancement in cyclic stability relative to the mono-amine counterpart. This work demonstrates the synergistic benefits of industrial waste valorization, pore structure engineering, and mixed-amine chemistry, offering a scalable and sustainable route toward next-generation solid adsorbents for carbon capture.

Boron powder exhibits exceptionally high gravimetric and volumetric calorific values, granting boron-rich propellants a significantly higher theoretical specific impulse compared to conventional hydrocarbon-based fuels. However, its practical application is severely limited by difficult ignition and incomplete combustion, resulting from the inherent oxide layer on the boron surface. Addressing these combustion inefficiencies is therefore critical. In this work, a series of modified B@FP composites with gradient fluoropolymer coating thicknesses were successfully synthesized through in situ polymerization of 1H,1H,2H,2H-perfluorooctyl acrylate (FOA) onto boron powder, where the coating mass was precisely tailored by varying the FOA monomer concentration. The surface morphology, elemental distribution, chemical composition, and hydrophobicity of the B@FP composites were comprehensively characterized. Their oxidation behavior, ignition performance, and combustion dynamics were further investigated. The results indicate that the fluoropolymer coating significantly reduces the ignition temperature of boron while increasing both the combustion heat and total exothermic enthalpy. Moreover, in combustion systems with ammonium perchlorate (AP) as oxidizer, the B@FP-1/AP mixture demonstrated higher combustion temperatures and a more vigorous reaction. Ultimately, the effect of the modified boron composites on the combustion performance of composite propellants was thoroughly evaluated, providing valuable insights for enhancing energy release efficiency in boron-containing propellant systems.

Delayed endothelialization and inadequate matrix remodeling remain major obstacles in the development of small-diameter vascular grafts (SDVGs; <6 mm). To address these challenges, we developed an immunomodulatory tissue-engineered vascular graft (iTEVG) by integrating hollow mesoporous silica nanoparticles (HMSNs) with tailored mesopore sizes as delivery carriers for immunoregulatory factors. VEGF was selectively immobilized on the intimal surface, while the adventitia incorporated a sequential release system for VEGF and IL-4. VEGF exhibited rapid release (64.04 ± 4.44% in 7 days), promoting monocyte recruitment and adventitial neovascularization, while IL-4 showed sustained release (65.94 ± 2.06% over 28 days), driving long-term M2 macrophage polarization. In rats, iTEVGs achieved 88% endothelial coverage and smooth muscle cell infiltration within 1 month, full-thickness cellularization with a complete trilaminar structure by 3 months, and maintained mechanical integrity without aneurysm formation up to 6 months. This spatially partitioned platform, built on an acellular vascular scaffold, enables precise spatiotemporal regulation of the immune microenvironment and offers a design paradigm that synergistically promotes endothelialization and vascular matrix remodeling. The “intima-targeted regeneration and adventitia-sequential-release” strategy provides a promising template for SDVG design that may be extended to other complex organ constructs.

Construction of positively charged nanofiltration membranes is essential for extracting lithium ions from salt-lake brine to meet the growing demand of the new energy industry. However, conventional membranes suffer from low water permeability due to the large thickness of the fabricated positive-charged polyamide (PA) layer, which increases transport resistance. To address this challenge, a porous interlayer was introduced to regulate the formation of the PA layer and accelerate water transport. Specifically, water-dispersible conjugated microporous polymer (CMP) fibers were synthesized and blended with positively charged polyethyleneimine (PEI) to form a porous, positively charged interlayer. The PEI in this interlayer further participated in the interfacial polymerization process, tailoring the PA morphology and converting the originally negative surface charge to positive. As a result, a dual positively charged membrane was obtained, featuring an enlarged surface area in the PA top layer and a porous structure in the interlayer. Benefiting from the synergistic effects of the Donnan exclusion and reduced transport resistance, the membrane exhibited outstanding separation performance in purifying lithium from a Mg 2+ /Li + mixed solution (mass ratio 20), achieving a water permeance of 11.3 L m −2 h −1 ⋅bar −1 and a separation factor of 43.8. Furthermore, the membrane maintained stable performance during a 10-day continuous operation, demonstrating strong promise for practical applications.

Ractopamine (RAC), a banned β-adrenergic agonist, poses severe risks to human health, necessitating rapid and ultrasensitive detection methods. This work presents a novel dual-mode immunoassay utilizing peroxidase-mimicking Au@Pt core-shell nanozymes for the colorimetric and photothermal detection of RAC. The optimized one-step synthesized Au@Pt nanoparticles (Au/Pt = 1:1) exhibited exceptional peroxidase-like activity (27.32 U/mg). After conjugation with monoclonal antibodies, the nanozymes served as immunoprobes in a one-step enzyme-linked immunosorbent assay (ELISA). The enhanced catalysis was elucidated by reactive oxygen species trapping, confirming hydroxyl radicals and singlet oxygen as key intermediates. The assay demonstrated outstanding sensitivity, with limits of detection at 5.32 pg/mL (colorimetric) and 1.03 pg/mL (photothermal), a significant improvement over conventional ELISA. Practical applicability was confirmed in spiked pork and pig urine, achieving recoveries of 86.0–113.0% (coefficient of variation<14.3%), offering a robust platform for on-site screening.

Water-rich hydrogels closely mimic human tissues, offering excellent biocompatibility, yet they often fall short in mechanical strength. Conversely, hydrophobic elastomers possess superior mechanical robustness and durability but typically lack the necessary biocompatibility for many medical applications. Conventional design strategies often struggle to integrate hydrophilic hydrogels and hydrophobic elastomers into a single material entity due to their inherently incompatible natures. Here, we introduce a universal synthesis strategy for simultaneously constructing hydrophobic elastomer and hydrophilic hydrogel networks, creating macroscopically homogeneous, tough elastomer-crosslinked hybrid (TECH) hydrogels. These hybrids exhibit superior mechanical strength and self-recovery, efficient energy dissipation and mechanical enhancement through the reversible deformation of robust elastomer microspheres. Importantly, this design strategy allows for the creation of a diverse family of TECH gels, combining various elastomers and hydrogels, all of which exhibit high sensitivity, durability, and precise motion detection, making them ideal for wearable strain sensors and electronic skin in advanced robotics. This work introduces a straightforward yet innovative approach to develop hybrid elastomer-hydrogel systems, traditionally incompatible, by integrating multiple functionalities of enhanced durability, adaptability, and sensitivity, suitable for flexible electronics, robotics, and biomedical devices, significantly advancing materials design and expanding their application scopes.

3D bioprinting enables the fabrication of biomimetic, cell-laden and pro-osteogenic constructs with high precision for bone regeneration. The ability of integrating favourable mechanical strength and multi-material interactive bioactivity in engineered constructs for efficient bone defect repair is still a challenge. Herein, we employed a dual-nozzle synergistic 3D bioprinting technology to fabricate a biocomposite scaffold that integrated interactive soft hydrogel filaments and hard polycaprolactone (PCL)-based filaments by mimicking weave patterns. The multi-material scaffold design aimed at providing features of suitable microstructure and long-term mechanical support, enhanced vascularized bone regeneration for bone repair. Chitosan/hyaluronic acid functionalized mesoporous silica nanoparticles bearing osteogenic protein on the surface and angiogenic drug in the pores were embedded into cell-supportive hydrogel bioink for promoting osteogenesis-angiogenesis coupling. Meanwhile, MgO nanoparticles were incorporated into structure-supportive PCL matrix for improving mechanical strength and compensating angiogenic/osteogenic activities by sustained release of Mg 2+ . The biocomposite scaffold had good cytocompatibility, and could stimulate in vitro angiogenic behavior and osteogenic differentiation. In vivo experiments revealed that the biocomposite scaffolds significantly enhanced vascularization and promoted bone regeneration on the cranial defect model. Overall, this study has offered a promising strategy for fabricating a multi-level adaptable 3D-bioprinted scaffold for bone defect repair through osteogenesis-angiogenesis coupling.

Probiotics play a vital role in regulating gut microbiota, strengthening the intestinal barrier, and modulating inflammation. However, their therapeutic efficacy is often compromised by harsh gastrointestinal conditions, rapid intestinal clearance, and lack of targeted delivery, which are particularly evident in ulcerative colitis (UC). To overcome these limitations, we developed a hyaluronic acid (HA)-based hydrogel (EcHA-G) through enzyme-mediated crosslinking of tyramine-functionalized HA and vanillin-modified gelatin. The resulting hydrogel exhibited desirable physicochemical properties, including a porous three-dimensional structure, rapid gelation, ultrafast self-healing, and macrophage-targeting capability. Oral administration of EcHA-G@probiotics markedly enhanced probiotic survival under gastric acid and bile stress by five and seven orders of magnitude, respectively, and significantly prolonged intestinal retention up to 96 h. The system achieved site-specific release, with 16% probiotic release in simulated gastric fluid and 84% in simulated intestinal fluid. In in vivo experiment, EcHA-G@probiotics effectively reduced pro-inflammatory cytokine expression (IL-6 by 82.4%, IL-1β by 96%, and TNF-α by 84.3%), restored the intestinal epithelial barrier, promoted macrophage polarization from the pro-inflammatory M1 to the anti-inflammatory M2 phenotype, and improved gut microbial diversity. Collectively, these results demonstrate that EcHA-G provides a promising oral delivery platform for targeted probiotic therapy and effective colitis alleviation.

Photothermal therapy (PTT) demonstrates significant potential as a cancer treatment; however, the protective autophagy triggered by PTT limits its effectiveness. This study fabricated multifunctional nanoplatforms, BM/GNPs@ZIF8 (BGZ), by concurrently coating the autophagy inhibitor bafilomycin (BM) and the photothermal agent gold nanoparticles (GNPs) in the ZIF8 using the "one-pot method." Subsequently, a targeted alteration was performed using folic acid (FA) to develop FA-BM/GNPs@ZIF8 (FA-BGZ). The co-delivery of BM and GNPs aims to integrate autophagy regulation with PTT in a synergistic manner. The final NPs, FA-BGZ, integrate pH responsiveness, PTT, and tumor-target abilities. The stability is markedly enhanced after coating with ZIF8 (GNPs@ZIF8), with minimal effect on photothermal performance. The FA-BGZ exhibits a photothermal significant impact of approximately 32.74%. Concurrent coating of BM can inhibit autophagy and interfere with cancer cells' defensive mechanisms. Additional in vitro biological experiments further validate that FA-BGZ exhibits a significant cytotoxic effect on cervical cancer SiHa cells under near-infrared (NIR) exposure (IC 50 : 16.52 ± 3.48 μg/mL), decreasing mitochondrial membrane potential (MMP), and increasing reactive oxygen species (ROS), which subsequently leads to cell apoptosis. These findings suggest that FA-BGZ is a promising nanodrug delivery system (NDDS) that could enhance synergistic treatment approaches in cervical cancer cells.

3-Monochloropropane-1,2-diol (3-MCPD) is a common contaminant generated during the heating process of foods. Because of the potential carcinogenic and toxic effects, measuring 3-MCPD is greatly significant to guarantee food security. Here, we developed a molecularly imprinted polyphenylboronic acid/carboxylated graphene (MIPPBA/CG)-based electrochemical sensor to determine 3-MCPD. The MIPPBA/CG composites were prepared by in-situ electrochemical deposition, and CG and MIPPBA were respectively used for electrical signal amplification and specific recognition of 3-MCPD. 3-MCPD was tested by square wave voltammetry utilizing the potassium ferricyanide probe. Under the optimal experimental conditions, our results showed that this sensor had the advantages of simplicity, rapidity, wide response range (1.0 × 10 −12 –1.0 × 10 −3 M), low detection limit (1.4 × 10 −13 M), good reproducibility, excellent stability, and high selectivity, and could detect the 3-MCPD content in different soy sauce samples with satisfactory results, which provided a promising approach for testing the food processing contaminant.
