Compared with conventional alloy nanoparticles and single-atom catalysts, SAAs provide local atomic coordination and intermetallic charge transfer, enabling efficient regulation of intermediate adsorption, proton-coupled electron-transfer kinetics, and catalytic selectivity. However, few reviews have systematically elucidated the rational design of atomically metal-induced carbon and nitrogen conversion. To bridge this gap, this minireview focuses on rationally designed SAAs for electrocatalytic carbon dioxide reduction, nitrate reduction, and C-N coupling, emphasizing the relationships among electronic structure modulation, intermetallic charge transfer, coordination environments, and intermediate adsorption. Moreover, the fundamental reaction mechanisms of carbon dioxide reduction, nitrate reduction, and C-N coupling are discussed to emphasize the pathways among reaction intermediates. Finally, current challenges and future opportunities are discussed, including scalable synthesis, durability enhancement, structural uniformity, electrochemical technologies Integration, and fundamental understanding. By integrating these perspectives, this minireview aims to provide a comprehensive framework for the rational design of next-generation atomically mixed nanoalloys for sustainable electrocatalytic carbon and nitrogen.","PeriodicalId":92,"journal":{"name":"Nanoscale","volume":"12 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2026-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149225841","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}

However, the synthesis routes, performance metrics, and article-level metadata are scattered across different literatures, which are difficult to standardize and reuse systematically. To this end, we have developed an end-to-end framework for literature knowledge extraction, data management and data mining. Based on large language models (LLMs), the framework is enhanced by domain-informed context engineering and lightweight fine-tuning. It has successfully extracted the structured information from approximately 50,000 research papers and integrated the extracted data into a relational knowledge base that contains 600,200 performance records and 202,300 synthesis records. The constructed knowledge database is supported by our proposed multi-agent SQL workflow for natural-language retrieval. To further assess the utility of the extracted knowledge, we have incorporated the band-gap records in literatures into C2DB-based band-gap prediction benchmark to conduct the external evaluation by using five-fold cross-validation. The inclusion of the extracted records yielded stable mean R2 and pooled MAE. Further SHAP analysis indicates that the model predictions are mainly driven by physically meaningful descriptors related to thermodynamic stability, elemental periodicity, local coordination environments, and learned CHGNet representations. The results show that the LLM-extracted literature data are not only the searchable text resources, but also can be incorporated into quantitative modeling and interpretability analysis, thereby facilitating data-driven materials discovery, performance optimization, and mechanistic understanding.","PeriodicalId":92,"journal":{"name":"Nanoscale","volume":"13 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2026-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149225847","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}

In this study, we developed hybrid Sr-Fe3O4/Fe3C/reduced graphene oxide (rGO) electrodes supported on conductive carbonized cotton fabric via a combination of solvothermal synthesis and supersonic cold-spray deposition, followed by controlled annealing. The cold-spray process facilitated the uniform, binder-free deposition of rGO-enwrapped Sr–Fe precursor particles onto temperature-sensitive cotton textiles without structural damage. Subsequent carbonization induced a phase evolution toward a mixed Fe3O4/Fe3C morphology that was strongly coupled with the graphitized carbon matrix. Systematic annealing between 750 and 825 °C revealed that the microstructure, crystallinity, and phase distribution were temperature-dependent. The optimal SF775 electrode was uniformly coated with Sr-Fe3O4/Fe3C and rGO on a carbonized cotton fibrous network. The SF775 electrode delivered a maximum areal capacitance of 1050 mF cm−2 at 5 mA cm−2, along with an energy density of 145.8 µWh cm−2 at a power density of 10 mW cm−2. Furthermore, the device exhibited excellent mechanical flexibility and durability, retaining its performance after 1000 bending cycles. These results indicate that high-performance textile-based Sr-Fe3O4/Fe3C electrodes produced via cold-spray deposition and thermal phase evolution are promising candidates for wearable supercapacitors.","PeriodicalId":92,"journal":{"name":"Nanoscale","volume":"16 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2026-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149218322","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}

Traditional metallic thermal conductors are heavily restricted by their substantial mass density and poor mechanical processability in lightweight electronics, demanding anisotropic materials that can provide robust thermal insulation across the out-of-plane direction while facilitating rapid heat dissipation along the in-plane direction. Here, we fabricate scalable and highly aligned Ti3C2Tx MXene films using the minimally intensive layer delamination method followed by vacuum-assisted filtration. Employing frequency-domain thermoreflectance, we achieve a precise characterization of directional heat transport on identical samples, revealing an exceptional thermal anisotropy ratio of 85. The fabricated films exhibit a significantly suppressed room-temperature out-of-plane thermal conductivity of 0.54 ± 0.09 W m⁻¹ K⁻¹ and an in-plane thermal conductivity of 46 ± 6 W m⁻¹ K⁻¹. Temperature-dependent characterization shows that out-of-plane thermal conductivity exhibits a positive temperature coefficient up to 353 K before stabilizing into a saturation plateau near 373 K, confirming that cross-plane heat transport is fundamentally regulated by the dense interlayer physical boundaries. At the microscopic interface, surface hydroxyl groups and interfacial hydrogen-bonding networks may modify local inter-flake phonon transport channels. The in-plane thermal conductivity decreases overall with increasing temperature, reducing the anisotropy while preserving substantial directional contrast. This work provides a versatile and high-performance platform for implementing structurally oriented MXene assemblies in advanced directional thermal management.","PeriodicalId":92,"journal":{"name":"Nanoscale","volume":"24 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2026-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149218323","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}

In this work, we construct monolayer WS2 integrated with size-controlled silver nanocube-on-mirror (NCoM) nanocavities and explore the influence of cavity resonance on its optical emission characteristics. By adjusting the nanocube dimensions, the plasmonic modes are engineered to simultaneously couple with the excitation field and WS2 emission, leading to strongly enhanced photoluminescence. Considering the effective excitation area of individual nanocavities, a local enhancement factor of approximately 103 is obtained under optimized resonance conditions. Furthermore, excitation-power-dependent measurements reveal a pronounced redistribution between exciton and trion contributions. Unlike the WS2/Ag planar structure, where trion emission remains dominant, the optimally coupled NCoM structure exhibits a gradual evolution toward exciton-dominated emission with increasing excitation power. This transition originates from the interplay among plasmonic resonance matching, localized electromagnetic confinement, and excitation-induced carrier and thermal effects at the metal–semiconductor interface. These findings highlight plasmonic nanocavities as an effective platform for manipulating excitonic emission processes in two-dimensional semiconductor systems.","PeriodicalId":92,"journal":{"name":"Nanoscale","volume":"73 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2026-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149218319","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}

However, the development of cathode materials that simultaneously achieve rapid ion diffusion kinetics, high optical contrast, substantial charge storage capacity, and long-term cycling stability remains a formidable challenge. Here, an in-situ annealing spray-coating process is conducted to prepare crystallized hydrated vanadium oxide (V₂O₅·1.6H₂O) cathode thin films. The V₂O₅·1.6H₂O films exhibit a well-ordered bilayer structure with an expanded interlayer spacing. This unique crystallized hydrated architecture, combined with interlayer water molecules that act as both structural “pillars” and Zn²⁺ transport facilitators, endows the material with enhanced and reversible Zn²⁺ intercalation/deintercalation kinetics, high optical modulation, and reversibility. As a result, the optimized device (ZECDs-2) shows good balance among optical contrast (66.69% at 650 nm), switching speed (tc=2.3 s, tb=6.7 s), coloration efficiency (38.81 cm² C⁻¹), and areal capacity (12.1 μAh cm⁻² at 0.5 mA cm⁻²). The device also exhibits good energy retrieval capability for energy saving.

This review article aims to cover the advances in the development of nanofiber-based strain sensors. Initially, we look at the current state of the broader field of strain sensors, defining their purpose, use, and potential applications. This is followed by a detailed background of various types of strain sensors covering the response mechanisms of resistive and capacitive type sensors. We have provided expansive coverage of various parameters necessary to define the performance of a strain sensor including tensile properties, gauge factor (GF), linearity, response and recovery time and durability. Since the focus of this review is on nanofibers-based strain sensors, we describe the various common methods to prepare nanofibers such as electrospinning and nebulization spinning. In addition, a summary of various conducting polymers and composites made from different non-conducting polymeric backbones is provided in this review. Furthermore, their potential applications in medical, sports and virtual reality industries are discussed. Finally, the research gaps which prevent these sensors from commercialization are discussed in the conclusions section along with the scope of future work to ensure the translation of such strain sensors to the market.","PeriodicalId":92,"journal":{"name":"Nanoscale","volume":"162 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2026-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149218317","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}

In this work, we systematically analyse how these organic-ligand-free Au NCs interact with their ionic nano-environment, focusing on the impacts of cation valency and cation hydration enthalpy. Thereto, micromolar concentrations of Na+, Ca2+, Al3+, and Ce3+ are added during synthesis (in situ) and corresponding millimolar concentrations to pre-formed aqueous Au NCs (ex situ) at alkaline pH, characterising particle size distributions and crystal structure by analytical ultracentrifugation and HR-TEM, surface charge density by zeta-potential measurements, as well as optical properties via absorbance, emission, fluorescence lifetime, and quantum yield. Our findings reveal a pronounced influence of Al3+ ions on the particle formation process, yielding unique bimodal size distributions charge screening and inversion of the surface charge from negative to positive values. This is attributed to element-specific cation adsorption to Au-O surface sites, while the impact of Na+ and Ca2+, as well as pH, was negligible. Furthermore, we find a pronounced blue shift of the emission wavelengths, indicating that the adsorption of the highly charged Al3+ can directly affect the electronic structure of the Au NCs and their HOMO–LUMO bandgap energy. Ex situ experiments further show cation-specific changes in emission wavelength and intensity, with blue shifts for Al3+ and red shifts for Ce3+, suggesting the potential of ligand-free Au NCs as candidate materials for ion-specific sensors, which may be useful in environmental analytics, where trivalent ions like Al3+ are of particular relevance.","PeriodicalId":92,"journal":{"name":"Nanoscale","volume":"16 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2026-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149218320","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 report the simultaneous exfoliation and functionalization of MoS2 with different maleimides in short times (10 min.) using mechanochemistry. The resulting few-layer functionalized MoS2 materials are thoroughly characterized by TEM, AFM, Raman spectroscopy, DRIFT, XPS, and solid-state 13C-NMR, collectively confirming both the exfoliation to few-layer flakes (average thickness 5 ± 1 nm) and the formation of covalent S-C bonds. Critically, the choice of maleimide functional group allows direct tuning of the dispersibility of the functionalized material in a range of green solvents, yielding stable dispersions in isopropanol, water, or ethyl acetate depending on the substituent. This rapid, scalable, and solvent-free approach opens a practical route to covalently functionalized MoS2 powders for downstream applications.","PeriodicalId":92,"journal":{"name":"Nanoscale","volume":"5 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2026-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149218318","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}
