By the generation of heat locally near catalytic sites, this approach reduces thermal transfer limitations typically encountered in externally heated systems. The optimized mixture achieved 46% methanol conversion at 150 °C under induction heating compared to the 225 °C required for similar performance using conventional oven heating. The stability and performance of the mixture were assessed under both inert and reactive conditions. A solid-state reaction between the catalyst and magnetite was observed during inert gas heating, but this was effectively suppressed under the reducing methanol reforming stream. Durability tests showed stable activity with no significant copper sintering or performance loss over a period of 3 h. Magnetite-mediated localized heating enabled an efficient reaction while maintaining a low overall bed temperature. This work demonstrates the potential of catalyst–susceptor integration to enhance thermal efficiency in heterogeneous catalysis. The findings highlight design strategies for applying induction heating to catalytic systems, offering improved energy utilization and operational control for gas-phase reactions.","PeriodicalId":6,"journal":{"name":"ACS Applied Nano Materials","volume":"8 34","pages":"16896–16904"},"PeriodicalIF":5.5,"publicationDate":"2025-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144911406","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, challenges remain due to their inconsistencies in particle size, emission spectra, quantum yield, and stability, factors that hinder their use in single-particle emitters, as such variability can result in unpredictable optical behavior and complicate integration into reliable optoelectronic or quantum photonic systems. Here, we systematically evaluate the interbatch and intrabatch variability of nine CsPbBr3 nanocrystal batches synthesized across three independent days. Using single-particle spectroscopy, ensemble measurements, and multivariate statistical tools (principal component analysis (PCA) and permutational multivariate analysis of variance (PERMANOVA)), we show that batch-to-batch variability is significant and primarily driven by uncontrolled differences in aggregation and surface ligand coverage. Postsynthetic treatment with oleylamine increases emissive particle density and an ensemble quantum yield but does not immediately enhance the single-particle ON-time fraction (i.e., stability). Over a 30 day aging period (in dark ambient conditions), all samples, regardless of treatment, converge toward a stable nanocrystal population with a narrower size distribution, reduced spectral and blinking heterogeneity, and consistent photophysical behavior. This equilibrium state arises from the gradual elimination of small and large particles and slow surface passivation. This work clarifies the inconsistencies reported in CsPbBr3 nanocrystals and provides guidelines for producing CsPbBr3 nanocrystals for application to single-particle emitters.","PeriodicalId":6,"journal":{"name":"ACS Applied Nano Materials","volume":"8 33","pages":"16603–16613"},"PeriodicalIF":5.5,"publicationDate":"2025-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144885174","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 present a structure-based investigation of the ORR activity of atomically precise Pt-based subnanoclusters (sub-NCs), alloyed with nickel (Ni) or cobalt (Co), prepared via size- and composition-selective deposition using magnetron sputtering. For a series of carbon-supported alloyed sub-NCs, PtnNim (n = 3–7) and PtnCom (n = 4–8), the ORR mass activities were evaluated, with Pt5Ni1, Pt5Co1, Pt6Ni2, and Pt6Co2 exhibiting activities 2.1–2.5 times higher than that of commercial standard Pt/C. Combined structural analysis using X-ray absorption fine structure and density functional theory revealed charge redistribution within the alloyed sub-NCs, where bonding to the carbon support is mediated by two Pt anchor atoms, while Ni and Co atoms remain unanchored. These findings demonstrate that atomicity-controlled alloy sub-NCs provide a rational design platform for next-generation PEMFC catalysts with enhanced activity and a tunable electronic structure.","PeriodicalId":6,"journal":{"name":"ACS Applied Nano Materials","volume":"8 34","pages":"16748–16758"},"PeriodicalIF":5.5,"publicationDate":"2025-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144911407","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 study evaluates Pc and Nc derivatives optimized for the NIR-I (700–980 nm) and NIR-II (980–1700 nm) spectral windows. A series of dyes were synthesized by varying metal centers within two Pc and Nc scaffolds, and their absorption trends were characterized.

Using a murine mammary tumor model, CuNc(Octa) and SnNc(Octa) emerged as the most effective NIR-I and NIR-II candidates, respectively. NIR-II phototherapy demonstrated superior tumor ablation due to deeper penetration and higher permissible exposure limits but raised safety concerns from rapid heating of healthy tissue.

Here in this work, well-known potential candidates Li1.3Al0.3Ti1.7(PO4)3 (LATP, a solid-state inorganic electrolyte) and PVDF-HFP (a gel polymer electrolyte) were used to make the composite electrolyte. LATP is a NASICON-type Li-ion conductor that has garnered significant interest owing to the rapid Li+ conductivity and appreciable stability toward the air. The silane coupling agents (SCA) are an effective way to reduce particle aggregation and promote the uniform distribution of LATP over the PVDF-HFP matrix. It promotes the interaction between the organic–inorganic interface in the QSSE through the shared chemical bridging effect and the unique amino effect. To evaluate the optimum concentration of the gel-polymer electrolyte, the PVDF-HFP and LiClO4 concentrations were optimized, and the maximum ionic conductivity of 1.63 mS/cm was attained. Furthermore, the LATP was surface-modified with an amine-functionalized silane coupling agent (APTES) to enhance the interaction between PVDF-HFP and LATP. An amorphous layer was observed over the surface-modified LATP. The silane functionalization completely reveals the Lewis acid sites of LATP, while the −NH3+ from APTES in polysiloxanes further augments the anion adsorption capacity of LATP through electrostatic interactions. The highest ionic conductivity of 3.01 mS/cm was achieved with 5 wt % Si@LATP into the PVDF-HFP/LiClO4 matrix.","PeriodicalId":6,"journal":{"name":"ACS Applied Nano Materials","volume":"8 34","pages":"16706–16716"},"PeriodicalIF":5.5,"publicationDate":"2025-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.acs.org/doi/pdf/10.1021/acsanm.5c02618","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144911404","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The MDDR comprised a magnetically responsive substrate and a DNA reactor; the two parts were connected by DNA hybridization. The target induced dissociation of the DNA reactor from the substrate by competitive binding to the aptamer, converting the target concentration into the number of DNA reactors.

Among these materials, biphenylene (BPN) stands out due to its nonbenzenoid topology, intrinsic metallicity, and high thermal stability, offering unique opportunities beyond graphene. However, the fundamental nature of BPN–metal interfaces, particularly how the substrate influences their structural, electronic, and catalytic properties, remains largely unexplored. In this work, we employ first-principles density functional theory (DFT) calculations to investigate these properties for BPN supported on (111) surfaces of Ag, Au, Ni, Pd, Pt, Cu, Al, and the Cu3Au alloy. Our results show that the interaction strength between BPN and the substrate governs its stability, corrugation, electronic hybridization, and interfacial charge transfer. In particular, we observe a clear trend where weakly interacting metals preserve the intrinsic features of BPN, while more reactive substrates lead to significant structural and electronic modifications. We further evaluate the hydrogen evolution reaction (HER) activity of these systems, identifying Pd, Pt, Ag, and Cu as promising catalysts. Notably, Ag and Cu offer a favorable combination of catalytic performance, cost, and chemical stability. These findings provide valuable insights into the design of BPN–metal interfaces for future applications in catalysis and nanoelectronics.","PeriodicalId":6,"journal":{"name":"ACS Applied Nano Materials","volume":"8 33","pages":"16349–16360"},"PeriodicalIF":5.5,"publicationDate":"2025-08-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.acs.org/doi/pdf/10.1021/acsanm.5c02590","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144885306","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
