Reasonable design core@shell heterostructures is essential for efficient photocatalytic reduction of Cr(VI) in water, as such architectures not only enhance light absorption but also facilitate light-induced charge separation and transfer. Herein, ZnIn 2 S 4 (ZIS) nanosheets were grown in situ on NiCo 2 O 4 hollow nanospheres to construct a NiCo 2 O 4 @ZIS heterostructured photocatalyst for efficient Cr(VI) reduction. The optimal 6 wt% NiCo 2 O 4 @ZIS achieves 100 % photocatalytic reduction efficiency for Cr(VI) within 10 min at pH 3, along with excellent cycling stability, outperforming pure ZIS and most previously reported ZIS-based catalysts. The improved photocatalytic activity is attributed to the unique heterostructure and composition of NiCo 2 O 4 @ZIS, where intimate interfacial contact facilitates charge separation and transfer while suppressing charge recombination. Additionally, homogeneous arrangement of ZIS nanosheets over NiCo 2 O 4 raises the quantity of active sites and enhances light harvesting. This study presents a viable strategy for constructing core@shell heterostructured photocatalysts based on ZIS toward highly efficient Cr(VI) reduction.

Granulated blast furnace slag (GBFS) is an industrial by-product with high latent activity generated during pig iron smelting, and its unique vitreous structure results in poor grindability. Therefore, activating the latent activity and improving the grindability of GBFS have become research hotspots in the relevant field. In this study, a low-molecular-weight polymer was synthesized using 2-acrylamido-2-methylpropanesulfonic acid (AMPS), hydroxypropyl acrylate (HPA) and diethylene glycol monovinyl ether (DEGVE) as polymerizable monomers, and then compounded with polyhydric alcohol to prepare a polymer grinding aid suitable for GBFS. The effects of the polymer grinding aid on grinding efficiency and hydration properties of GBFS-blended cement paste were systematically investigated. The results showed that the particle size of GBFS ground with the polymer grinding aid was slightly coarser than that of the alkanolamine-treated sample. But the polymer grinding aid could optimize the cross-linked structure of hydration products and improve the early age and long-term strengths of GBFS-blended cement. When the dosages of initiator and chain transfer agent accounted for 1.28% and 5.14% of the total monomer mass, respectively, and the monomer molar ratio satisfied n (DEGVE):n (AMPS):n (HPA) = 1:2.65:0.5, the obtained polymer grinding aid provides a better balance between particle-size distribution optimization of GBFS and strength development of GBFS-blended cement, while the individual fineness parameters remain comparable to or slightly lower than the sample prepared with reference alkanolamine-based grinding aid. Compared with the alkanolamine-based grinding aids, the volume fractions of GBFS particles with particle sizes of 0–3 μm and above 64 μm treated by the polymer grinding aid decrease by 5.4% and 76.0%, respectively, while the volume fraction of particles with particle sizes of 32–64 μm increases by 12.2%. Correspondingly, the 7 d and 28 d compressive strengths of the GBFS-based cementitious materials are increased by 8.4% and 4.3%, respectively.

A composite film of DRP and HPS was developed. • DRP and HPS enhanced composite film properties through synergistic interaction. • The synergistic effect was due to the formation of hydrogen bonds between DRP and HPS. • Preservation abilities of strawberries were significantly strengthened with eugenol-loaded composite film. In this study, Dictyophora rubrovalvata polysaccharide (DRP) was introduced into starch (CS) and hydroxypropyl starch (HPS) matrices to develop a composite film with enhanced physicochemical properties and investigate its potential for use in fruit preservation. Films based on CS, CS-DRP, HPS and HPS-DRP were prepared via solution casting method. The structural characteristics of the films were investigated using rheology, spectroscopy, and textural analyses, alongside systematic evaluation of their physical properties. Results showed that among all groups, the HPS-DRP film exhibited the best polymer compatibility, with its film-forming solution demonstrating an elastic-dominated rheological system and a smooth, uniform microstructure. Meanwhile, the hydrogen-bond interactions between DRP and HPS conferred superior mechanical properties, barrier performance and thermal stability to the film, achieving a tensile strength of 4.55 MPa, an elongation at break of 86.81%, a water vapor permeability of 5.63 × 10 −10 g·m −1 ·s −1 ·Pa −1 , and a residual rate of 21.87% after thermal degradation. Following the incorporation of eugenol, the HPS-DRP composite film exhibited good antimicrobial activity and effectively extended the shelf life when applied to strawberry preservation. These results demonstrate that HPS-DRP composite film holds broad application prospects as an active packaging material in fruit preservation.

STF 4 stabilizes Tea Tree Oil with 84.2% encapsulation efficiency in emulsion. • STFEF 10 achieves 98% sterilization via photothermal synergy. • STFEF 10 had enhanced mechanical and UV/water vapor/oxygen barrier properties. • STFEF 10 can effectively prolong the shelf life of berries. Natural antimicrobial agents are both environmentally friendly and safe, and exhibit excellent biocompatibility. However, their instability and rapid release characteristics limit their application in food preservation packaging. In this study, a photothermal-responsive packaging film was developed by incorporating a Pickering emulsion of soy protein isolate-tannic acid-Fe 3+ (STF) nanoparticles stabilizing tea tree oil (TTO) into a chitosan (CS)/gelatin (Gel) matrix. The STF nanoparticles, synthesized via coordination-driven self-assembly, stabilized the Pickering emulsion and achieved an encapsulation efficiency of 84% for TTO. Under near-infrared (NIR) irradiation, STF nanoparticles transform light energy into thermal energy. On the one hand, the localized increase in temperature provides the film with a certain sterilizing effect. On the other hand, the film allows for the rapid, controlled release of tea tree oil as needed. Through the synergistic effect of localized thermal therapy and controlled release of essential oils, the film exhibits over 98% antibacterial activity against E. coli and S. aureus . Furthermore, the resultant film has outstanding mechanical strength, barrier properties, and antioxidant effects. Preservation experiments were ultimately carried out using strawberries and grapes as representative berries, and the results showed that the film can extend the shelf life by 3–8 days depending on the fruit type. These results demonstrate the application potential of this photothermal controlled-release film in the field of berry preservation.

Gas-forming gas–liquid systems are common in pharmaceutical, chemical, and energy processes. Microchannel reactors offer an effective platform for intensifying such multiphase systems. In this study, bubble growth dynamics in viscous Newtonian (glycerol) and non-Newtonian (xanthan gum) fluids within a rectangular microchannel were investigated experimentally and theoretically. Carbon dioxide bubbles were generated via the reaction of sulfuric acid with sodium bicarbonate. A high-speed camera was used to observe bubble evolution. Results showed that increasing concentrations of either glycerol or xanthan gum reduced bubble growth rates, whereas total flow rate had a negligible effect. A theoretical model was developed to describe bubble growth with chemical reactions in both fluid types, and its predictions agreed remarkably well with experimental data. The insights obtained can be helpful for the design and optimization of gas–liquid microchannel reactors for relevant applications.

Elastomers are widely used in industrial, medical, and commercial fields. There is an urgent need for ideal elastomer that combine high toughness, recyclability, and degradability. However, their green and efficient preparation still faces severe challenges. This paper reports a simple one-pot in situ synthesis strategy utilizing biomass resources to produce bio-based elastomers. This process involves the in situ cross-linking of gelatin with ultra-low tannic acid content to form a homogeneous gelatin elastomer slurry. The resulting gelatin-based bioelastomer exhibits high mechanical performance, anti-ultraviolet capability, and soft characteristics. Furthermore, this material can safely biodegrade naturally, reducing environmental impact. These combined attributes position the bioelastomer as a strong candidate for emerging applications in flexible electronics, soft robotics, and biomedical engineering scaffolds, where mechanical durability, UV resistance, and environmental friendliness are concurrently required. By employing exclusively green and recyclable reagents, this one-pot strategy offers a practical pathway toward high-strength, degradable, and sustainable gelatin-based elastomers.

One-pot autocatalytic CRISPR biosensing offers a promising route for signal amplification without nucleic acid pre-amplification, but its efficiency is limited by an intrinsic readout-amplification conflict: the ssDNA reporter required for signal output competes with the autocatalytic mediator required for feedback amplification. Here, we report a biphasic spatiotemporal regulation strategy (BS-Cas12a system) to resolve this substrate competition for one-pot autocatalytic CRISPR biosensing of non-nucleic-acid targets. Mechanistic studies revealed that Cas12a preferentially cleaved the ssDNA reporter over the autocatalytic circular mediator, leading to insufficient mediator linearization and impaired autocatalytic amplification. A glycerol/water biphasic system was therefore constructed to spatially delay reporter access to activated Cas12a, allowing preferential cleavage of the autocatalytic mediator and subsequent generation of additional Cas12a activators. This biphasic system achieved a 3-fold increase in the autocatalytic amplification efficiency. By integrating an aptamer-mediated target-to-activator conversion module, non-nucleic-acid recognition was programmably converted into Cas12a activation. Using sulfadimethoxine as a model target, the platform achieved a detection limit of 65 pM and showed good recoveries in fish samples. The system was further extended to Cd 2+ and thrombin detection with limits of detection of 0.65 nM and 11.63 pM, respectively. Moreover, by replacing the fluorescent reporter with a FAM/biotin-labeled reporter, a lateral-flow readout was achieved. This work provides a kinetic-regulation strategy for modular one-pot Cir DNA autocatalytic biosensing with an independent and exchangeable reporter and expands CRISPR-based detection toward diverse non-nucleic-acid targets.

The prolonged application of synthetic fungicides presents substantial environmental hazards and potential toxicity to non-target organisms, including humans. Plasma-activated water (PAW) has emerged as a promising agent for pathogen inactivation; however, the physiological and biochemical mechanisms underlying its efficacy against the rice blast fungus, Magnaporthe oryzae , remain largely uncharacterized. In this study, we evaluated the antifungal activity of PAW against M. oryzae through in vitro and in vivo assays and characterized the corresponding cellular responses. Seedling rice blast forms spindle-shaped necrotic lesions on young leaves, causing seedling withering and providing fungal spores that trigger severe blast outbreaks in later rice growth stages and drastically cut grain yields. PAW treatment significantly inhibited conidial viability ( P<0.05 ) and markedly reduced disease severity in rice seedlings. Physiological and microscopic analyses indicated that PAW induced cell wall rupture, altered membrane permeability, and triggered mitochondrial dysfunction. These findings were corroborated by transcriptomic profiling, which identified the cell wall, plasma membrane, and mitochondria as the primary organelles targeted by PAW-derived reactive species. Our results elucidate the antifungal mode of action of PAW against M. oryzae and highlight its potential as a sustainable fungicidal alternative or a potent supplement to conventional chemical interventions.

Light driven soft actuators often struggle to integrate robust mechanical toughness, dynamic spatial tunability, and reliable on demand adhesion within a single material system. Here, we present a near infrared (NIR) light responsive hydrogel featuring dynamic noncovalent networks that enable the rapid and reversible reconfiguration of mechanical properties. The structural network integrates PVA chains to provide initial mechanical resilience and environmental durability, while the thermal responsive boronic ester bonds act as crosslinking junctions to ensure fast transition to a soft elastic state. This integrated architecture achieves a rare balance between high initial stiffness and on demand dynamic actuation, overcoming the long-standing trade off in responsive soft matters. Furthermore, the localized photothermal cleavage of the dynamic bonds exposes functional groups, which significantly enhances the interfacial adhesion to diverse surfaces, reaching approximately 48 kPa on aluminum. The localized photothermal reduction in mechanical stiffness endows the hydrogel with precise spatial control, enabling the design of untethered bionic actuators and interactive sensors. Beyond mechanical actuation, the hydrogel serves as a highly sensitive wearable electronic device, achieving precise human motion detection and Morse code communication. Furthermore, the integration of a 4 × 4 spatial pressure sensor array provides reliable tactile feedback for robotic manipulation tasks. This work highlights a versatile design strategy for programmable hydrogels, paving opportunities for smart interfaces, advanced human machine interaction, and adaptive soft robotic systems.

Engineered conductive hydrogel bandage enables quantitative and interpretable wound pressure monitoring. • PEDOT network supports stable electromechanical transduction with ultralow hysteresis. • Laplace-guided analysis establishes a direct linkage between electrical signals and interfacial pressure. • High elasticity, rapid recovery, and long-term durability support reliable wearable sensing. Quantitative control of interface pressure is essential for effective chronic wound treatment, yet remains challenging due to the lack of reliable real-time sensing strategies with direct physical interpretability. Here, we establish a physics-guided conductive hydrogel bandage (CHB) integrating a Laplace-based analytical framework to enable quantitative mapping between electrical signals and interfacial pressure. The CHB comprises a poly(vinyl alcohol)-reinforced polyacrylamide network, where dynamic hydrogen bonds between hydroxyl and amide groups dissociate to dissipate energy and reform upon release, preserving elasticity and structural integrity over 5000 cycles. A continuous poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) conductive pathway is further incorporated to provide stable signal transduction with low hysteresis (<5%) and a near-linear response (gauge factor (GF) = 1.4) at 350% strain. By integrating the calibrated resistance–strain and strain–force relationships, strain-dependent bandage width, and wrapping radius into Laplace's law, the CHB converts relative resistance changes into quantitative interface pressure, yielding close agreement between predicted pressures and measurements from a commercial pressure sensor (regression slope = 1.05). Beyond conventional empirical sensing, our approach provides a physically interpretable and potentially generalizable framework for quantitative pressure analysis in flexible wearable sensing. Together with its asymmetric adhesion, favorable in vitro cytocompatibility, skin compatibility, and suitable water vapor permeability, the system offers a promising platform for quantitative wound pressure monitoring to support more consistent compression management of chronic wounds. A highly elastic conductive hydrogel bandage converts deformation-induced resistance changes into quantitative interface pressure through a Laplace-based model. Under conformal wrapping on cylindrical surfaces, mechanical strain generates stable resistance variations (ΔR/R₀), which are correlated with pressure by considering bandage tension and curvature. The calculated pressure agrees well with experimental measurements, demonstrating a physically interpretable strategy for pressure quantification in wearable bandage systems.

UPG-PAN integrates self-lubrication, wet adhesion, and fatigue resistance. • UPG-2 achieved 3.22 MPa strength and 92.5% fatigue resistance. • Glycerol migration lowered contact angle to 28° and friction to 0.035. • PAN-2 provided 27.53 kPa wet adhesion to subchondral bone. • UPG-PAN showed good cytocompatibility and milder early tissue response. Articular cartilage remains a significant clinical challenge. The ideal implant would support joint loads, resist fatigue, reduce friction, adhere to wet subchondral bone and demonstrate good biocompatibility. Although hydrogels have a hydration profile similar to that of cartilage, many lack long-term durability under load. Elastomers have higher mechanical strength, but they often show poor surface lubrication and weak wet-tissue adhesion. In this study, we developed a biomimetic bilayer elastomeric cartilage substitute, named UPG-PAN. It contains a self-lubricating upper elastomer layer, UPG, and a wet-adhesive lower hydrogel layer, PAN. In the UPG layer, thermoplastic polyurethane (TPU) forms the elastic load-bearing framework. Poly(ethylene glycol)-modified poly(glycerol sebacate) (PEGS) and glycerol (Gly) regulate chain entanglement, reversible hydrogen bonding, surface hydration, and energy dissipation. The UPG-2 elastomers maintained MPa-level compressive strength (∼3.22 MPa), tunable modulus (∼1.58 MPa), stable cyclic compression behavior, and good fatigue resistance (∼92.5%). Gly migrated toward the material surface during formation and drying. This migration formed an OH-rich hydrated lubricating layer. The layer improved surface wettability and helped maintain low friction during reciprocating sliding (∼0.035 COF). The PAN layer was prepared by photocuring PEGS-Ac, PEGS-NH 2 , and acrylic acid (AAc). This layer formed a continuous UPG-PAN interface and strong wet adhesion to bone (∼27.53 kPa). The adhesion was related to interfacial chain interpenetration, hydrogen bonding, crosslinking, and electrostatic interactions. L929 cell culture and rat subcutaneous implantation showed good biological safety. Compared with TPU-PAN, UPG-PAN showed improved cytocompatibility and a milder early inflammatory response. Overall, UPG-PAN combines fatigue-resistant mechanical support, self-lubrication, wet fixation, and biocompatibility. This bilayer design may help slow local cartilage degeneration and delay invasive joint replacement in patients with focal cartilage defects.

The catalytic hydrogenolysis of glucose to produce 1,2-propylene glycol (1,2-PG) has opened promising avenues for sustainable chemical production. However, traditional Ru-based catalysts suffer from issues such as high metal loading, poor dispersion, and a tendency to agglomerate under harsh conditions, leading to rapid deactivation. This work reports a highly dispersed, low-loading Ru catalyst supported on a magnesium–aluminum ferrite (MAFO) spinel to address these limitations. Strong covalent metal–support interactions (CMSI) between Ru species and the MAFO support not only achieve efficient stabilization of Ru nanoparticles but also promote their redispersion. Under optimized reaction conditions (518 K, 5 MPa H 2 , and 1 h), the Ru/MAFO catalyst achieves 100% glucose conversion and 59.3% selectivity to 1,2-PG. Notably, the catalyst maintains outstanding activity and stability after six consecutive reaction cycles. This study provides an efficient and robust catalytic strategy for 1,2-PG production from glucose, offering significant insights for designing high-performance and stable catalysts for biomass valorization.
