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}

However, the extent of the observed effect varies greatly, the reasons remaining unclear. Here, we investigated the resonance-enhancement by trapping ytterbium-doped NaYF4 upconversion nanoparticles using a dual-wavelength optical tweezers setup operating at 976 nm (near-resonant) and 1064 nm (off-resonant). Combining power-spectral-density analysis and active drag-force calibration, we measured the trap stiffness and hydrodynamic particle size of each trapped particle at both wavelengths. Measured upconversion nanoparticle sizes ranged from the size of single particles to larger-sized clusters that we also observed by electron microscopy. Near-resonant trapping increased the trap stiffness about twofold for all particle sizes compared to off-resonant conditions. However, larger particles were trapped with a higher trap stiffness under both near- and off-resonant conditions. This increase with size suggests that trap stiffness measurements under near-resonant conditions without direct size measurements may overestimate the enhancement. Our results demonstrate that resonance effects enhance optical trapping, while emphasizing the critical roles of trapping power, particle size, and clustering in the quantitative evaluation of trapping enhancement.","PeriodicalId":92,"journal":{"name":"Nanoscale","volume":"1 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2026-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149226106","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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}

Graphene films offer high in-plane thermal conductivity, but rapid reduction of graphene oxide (GO) releases gases from oxygen-containing groups and can generate pores, interlayer damage, and poor film densification. Here, we report a precursor-design strategy that combines reduced graphene oxide nanosheets (GNs) with carboxylated cellulose nanofibers (CNFs). The composite films (GO/GNs-X) were prepared by blade coating, hot-press carbonization, and secondary Joule-heating graphitization. The combined precursor was designed to mitigate gas-release-induced damage and support carbon-network reconstruction during high-temperature treatment. The optimized GF, with a thickness of approximately 25 μm, reached an in-plane thermal conductivity of 950.5 ± 20 W m–1 K–1 and an electrical conductivity of 2.31 × 105 S m–1. At a comparable thickness, this thermal conductivity was 26.6% higher than that of an additive-free RGO-2600-ref film prepared without GNs/CNF modification. In LED heat-dissipation tests, the surface-centre temperature decreased from 83.7 to 40.4 °C. Because individual-additive controls were not included, the respective contributions of GNs and CNF could not be separated. These results establish combined precursor modification as a route to thin, lightweight graphene heat spreaders. Such films may be useful for thermal management in compact electronics, foldable devices, and aerospace systems.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"18 41","pages":"56299–56308"},"PeriodicalIF":7.8,"publicationDate":"2026-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149151913","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}

While most research focuses on near-infraredabsorbing perovskites, chloride-based wide-bandgap (>2.85 eV) perovskites with ultraviolet absorption offer superior CRI and high transparency. However, conventional solution methods face significant challenges in fabricating high-quality large-area films, which limits device performance and scalability. To address these challenges, we developed a scalable method for vapor deposition of high-quality FAPbCl 3 films (FA + = formamidinium) as functional units. A physically vapor-deposited PbCl 2 undergoes a reaction with FACl vapor under low pressure through a top-down diffusion reaction mechanism established through in situ UV-vis and Xray diffraction studies. The resulting films exhibit larger grains, enhanced crystallinity, and improved narrow-band absorption compared to their solution-processed counterparts.Combining the vapor-deposition of the perovskite absorber with chemical bath-deposition of a SnO 2 electron transport layer and thermal evaporation/sputtering of the charge-selective contacts and electrodes enables fully scalable fabrication of high-transparency FAPbCl 3 solar cells with a peak PCE of 0.87%, along with promising operational stability.

Here, we combine experiments, statistical analysis, and pseudo-two-dimensional electrochemical simulations to elucidate the origin of this counterintuitive behavior. We show that the divergence is closely associated with the phase-transformation characteristics of the LiFePO₄ cathode at high states of charge. During deep delithiation, the progressive transformation of LiFePO₄ to FePO₄ is accompanied by pronounced decreases in electronic conductivity and Li-ion diffusivity, making cell voltage increasingly sensitive to small variations in cell capacity. Under series connection, these cell capacity differences induce progressively larger SOC disparities during CV charging, leading to distinct open-circuit voltage evolution and polarization relaxation among cells. Because the total pack voltage is constrained, these differences are redistributed across the series-connected cells, causing lower-capacity cells to exhibit a terminal voltage increase and higher-capacity cells a terminal voltage decrease. We further establish a linear correlation between the cell voltage at the end of CV charge (Vcv-end) and cell capacity. Cell selection based on Vcv-end reduces the growth rate of end-of-discharge voltage divergence by approximately 50% in 1P3S packs and improves capacity retention over 900 cycles. These findings reveal how the intrinsic phase-transformation characteristics of LiFePO₄ govern voltage divergence in series-connected cells and provide a mechanistic basis for dynamic capacity screening and consistency management.","PeriodicalId":82,"journal":{"name":"Journal of Materials Chemistry A","volume":"18 1","pages":""},"PeriodicalIF":11.9,"publicationDate":"2026-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149225861","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}
