Here, we present a sequential-photocuring-assisted fabrication strategy that transforms planar multilayer structures into curved forms within a single material system. A wavelength-selective acrylate–epoxy resin is designed to create a deformable intermediate state under visible light, followed by a fixation-enabled final state through UV-triggered curing. A gradient-like curing strategy, involving time-dependent evolution of conversion during sequential irradiation, allows controlled partial epoxy conversion and provides both processability and subsequent reactivity. The second curing step induces simultaneous interfacial bonding and structural stiffening, enabling adhesive-free integration and fixation of the mold-imposed geometry. A multilayer patch antenna operating at 28 GHz is fabricated and transformed from planar to curved geometry while maintaining its performance. This approach provides a material-based framework for integrating planar-fabricated structures into three-dimensional form factors without thermoforming or adhesives.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"56 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2026-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149226002","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, dendrite formation and parasitic reactions at Zn metal anodes limit long-term cycling stability. Here, aramid nanofiber (ANF) hydrogel electrolytes are engineered by controlling the acid identity and solution pH during reprotonation. These variables regulate reprotonation kinetics, thereby shaping hydrogen-bond formation, molecular ordering, and the through-thickness morphology of the ANF network. The selected ANF hydrogel electrolyte exhibits a Young’s modulus of 1.1 MPa while maintaining an ionic conductivity of 30.8 mS cm–1. Its mechanically robust and ionically conductive network promotes compact Zn deposition and resists dendrite penetration. Consequently, Zn||Zn symmetric cells sustain stable plating/stripping for over 2000 h at 1.0 mA cm–2 with an areal capacity of 1.0 mAh cm–2. Compared with conventional glass-fiber-based cells, Zn||hydrated vanadium oxide full cells also exhibit improved high-rate capacity retention and retain over 88% of their initial capacity after 2000 cycles at 1.0 A g–1. These findings establish reprotonation kinetics as a practical design parameter for balancing mechanical robustness, ion transport, and interfacial stability in hydrogel electrolytes for durable aqueous zinc-ion batteries.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"291 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2026-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149226006","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By leveraging the ring-opening of thiazolidin-2-one with multifunctional amines, we establish a streamlined reaction that simultaneously constructs a covalent adaptable network (CAN) and triggers in situ CO2 evolution. This chemistry bypasses traditional reagents; instead, internal thiol groups react with ethylene carbonate to drive foaming under entirely catalyst-free conditions. By precisely tuning the tris(2-aminoethyl)amine ratio, we synchronize gas expansion with matrix vitrification, overcoming the structural collapse typical of nontraditional systems. The resulting foams feature hindered urea linkages that impart dissociative CAN behavior, enabling full chemical reprocessability and structural recovery over multiple cycles without compromising mechanical integrity.

To address this, we developed a core–shell microneedle (GS + IL-4@MN) patch loading Gymnema sylvestre (GS) extract and interleukin-4 (IL-4) as a promising therapeutic strategy. The patch comprised a 10 × 10 array of conical needles and the optimized shell-loading concentration of GS was determined to be 1.0 mg/mL. The GS-loaded outer shell can suppress the release of pro-inflammatory mediators, scavenge ROS, and strengthen antioxidant defenses, thereby attenuating local inflammation; the IL-4-encapsulated core induces macrophage polarization toward the M2 phenotype, mitigates the pro-inflammatory microenvironment, and modulates T-cell immunity, while enhancing cellular proliferation and migration to support tissue regeneration. In diabetic wound models, GS + IL-4@MN achieved wound-closure rates of 64.72 ± 6.3% at day 3 and 85.80 ± 3.6% at day 7, and re-epithelialization reached 91.52 ± 2.1% by day 14. Moreover, collagen deposition increased to 79.38 ± 4.3%, CD31-positive neovascularization reached 70.50 ± 3.7%, and the M1/M2 ratio decreased to 0.3, indicating marked inflammatory resolution and regenerative activation. In summary, this core–shell MN system achieves multidimensional regulation of the pathological microenvironment of diabetic wounds through a dual mechanism: outer-layer inflammatory suppression and inner-layer microenvironment reset, and offers a new avenue for promoting diabetic wound healing.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"18 41","pages":"55930–55945"},"PeriodicalIF":7.8,"publicationDate":"2026-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149126083","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This review examines BODIPY-based fluorescent sensing of selected hazardous chemicals at the molecular level, supramolecular and aggregated-state level, and sensing material and device level, focusing on how regulation at different levels addresses different performance limitations. At the molecular level, recognition unit design, conformational regulation, and boron-center transformation regulate analyte recognition and signal transduction. At the supramolecular and aggregated-state level, noncovalent interactions, aggregation-state regulation, and molecular packing influence emission behavior and signal stability. At the sensing material and device level, interfacial and transport regulation, sensing material construction, and device integration and signal readout improve analyte accessibility and practical detection performance. This review provides a systematic framework for understanding the factors that govern BODIPY-based fluorescence sensing. This multilevel classification facilitates the identification of major factors limiting sensing performance and the corresponding regulation strategies, thereby providing guidance for the rational design and optimization of BODIPY-based fluorescent sensing systems.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"18 41","pages":"55735–55752"},"PeriodicalIF":7.8,"publicationDate":"2026-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149151163","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we reported a near-infrared (NIR)-activated reactive oxygen species (ROS)/ nitric oxide (NO) cascade nanocomposite, UCeSi-L@CA, designed to amplify oxidative/nitrosative antibacterial stress while promoting infected wound healing. UCeSi-L@CA was constructed from Ce6-loaded mesoporous silica-coated upconversion nanoparticles, with L-arginine conjugated through surface carboxyl groups and cinnamaldehyde loaded into the mesopores. Upon NIR irradiation, upconversion nanoparticles activated Ce6 to generate abundant ROS. Cinnamaldehyde exerted direct antibacterial activity and inhibited glutathione-mediated ROS scavenging, thereby sustaining ROS accumulation and weakening bacterial antioxidant defense. The accumulated ROS further triggered NO production from L-arginine, establishing a ROS/NO cascade in which ROS and NO cooperatively damaged bacterial membranes, enhanced lipid peroxidation, and induced efficient bacterial killing. Beyond antibacterial activity, NO also contributed to infected tissue repair. In vitro, UCeSi-L@CA + NIR showed excellent killing against planktonic P. aeruginosa, effectively inhibited biofilm formation, eradicated bacteria within established biofilms, and suppressed biofilm regrowth. In the P. aeruginosa-infected wound model, UCeSi-L@CA + NIR markedly reduced local bacterial burden, attenuated infection-associated inflammation, accelerated wound closure, and promoted tissue repair, with favorable biocompatibility in vitro and in vivo. This nanocomposite presents a non-antibiotic nanotherapeutic strategy integrating NIR-triggered ROS generation, cinnamaldehyde-mediated GSH-defense inhibition, and L-arginine-derived NO release for treating refractory biofilm-associated wound infections.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"56 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2026-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149225986","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Lignocellulosic fibers are promising alternatives for acoustic diaphragms, paper-based packaging, and automotive interiors. However, their practical application is limited by the inherent trade-off between low density and mechanical performance, with most high-strength composites relying on densification or additional reinforcing phases that compromise lightweight characteristics. Here, inspired by the multiscale alignment of human muscle, we develop an oriented lignocellulose micro/nanofiber composite (O-LMU) through a flow-field-assisted assembly strategy. This approach enables the construction of a highly ordered multiscale fiber architecture coupled with optimized nanoscale interfaces. Multiscale simulations reveal that optimized interfacial interactions and hierarchical fiber alignment promote hydrogen-bond network reconstruction, mitigate stress concentration, and facilitate efficient load transfer within the fiber network. Therefore, O-LMU achieves a low density of 0.71 g·cm–3, a specific strength of 205 kN·m·kg–1, a tensile stiffness of 2245 kN·m–1, and a toughness of 394 J·m–2. Notably, O-LMU exhibits a specific strength that is 2.4 times that of the lignocellulosic nanofiber film. The material can be recycled by aqueous disintegration and biodegrades under natural soil conditions. This work establishes a structure-driven strategy for designing lightweight, strong, and sustainable lignocellulosic materials beyond conventional densification-based reinforcement approaches.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"3 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2026-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149225995","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, uncontrolled oxygen-vacancy concentrations can lead to unstable charge transport and switching variability, limiting reliable device operation. In this work, post-deposition N2 annealing was employed to regulate the oxygen-vacancy-related defect states of Pd/HfO2/a-IGZO/HfO2/Pd memristors. The a-IGZO layer was annealed in an N2 atmosphere at 300–600 °C, and the resulting changes in material properties, resistive switching behavior, and synaptic characteristics were systematically investigated. XPS and XRD analyses indicated that N2 annealing decreased the relative oxygen-deficient/defect-related O 1s component while maintaining the amorphous nature of the a-IGZO layer. Among the investigated conditions, the 500 °C-annealed device exhibited the most stable switching behavior, with reduced variation, improved retention and endurance characteristics, and reliable analog conductance modulation. Conduction mechanism analysis revealed that the optimized device maintained stable space-charge-limited current conduction, whereas excessive vacancy reduction at 600 °C promoted a premature transition toward the trap-filled-limit regime, resulting in degraded switching stability. Furthermore, the optimized device successfully emulated long-term potentiation/depression and paired-pulse facilitation, and its measured synaptic characteristics were validated through ANN-based MNIST pattern recognition and PPF-driven neuron circuit simulation. These results demonstrate that N2 annealing-induced oxygen-vacancy engineering is an effective strategy for improving the reliability and neuromorphic applicability of a-IGZO memristors.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"33 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2026-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149225998","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, we employ single-sided nuclear magnetic resonance (SS-NMR) to probe the in situ diffusion dynamics of water within solid-state nanochannels (SSNs) functionalized with UiO-66 metal–organic framework (MOF). We systematically compare two distinct synthetic protocols: a one-pot (OP) interfacial growth and a counter-diffusion (CD) method. By deconvoluting the NMR signal attenuation, we isolate a minor slow diffusion component corresponding to intraparticle micropores and a dominant fast diffusion component representing interparticle constructional porosity. Our results show that OP growth produces large particle agglomerates and poorly connected pores with narrow bottlenecks, forcing water along highly tortuous paths. Furthermore, leveraging the pH-responsive surface charge of UiO-66, we find that water mobility in the well-connected CD nanoarchitecture varies measurably with pH, consistent with a surface-charge effect, whereas OP membranes show a weaker, nonmonotonic variation, consistent with dominant geometric obstruction. These findings link nanochannel architecture directly to local water mobility and identify constructional porosity as a structural parameter to consider in MOF-based nanofluidic membranes.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"12 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2026-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149221493","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
