However, AFM-based three-dimensional single-particle reconstruction has hitherto not been possible due to the tip-sample convolution artifact that distorts AFM images of individual molecules, and the disconnect between two-dimensional AFM images of surface deposited molecules and their three-dimensional structures. Here, three-dimensional single-particle analysis was developed for rapid structure-based validation of protein structures using as few as a single AFM topology image, based on contact-point reconstruction AFM (CPR-AFM) in an integrative approach with cryo-electron microscopy maps available in the Electron Microscopy Data Bank by template matching. This approach was demonstrated on the structural validation of recombinant trimeric ectodomain of SARS-CoV-2 Spike glycoprotein to show its immediate utility for rapid structure-based quality-control in the recombinant expression and purification of Spike protein samples that can be used in vaccines and therapeutics research. These results show that three-dimensional single-particle reconstruction by AFM is possible, high signal-to-noise AFM imaging offers a rapid and cost-effective way of validation or identification of three-dimensional protein structures at single-particle level, and AFM linked to cryo-electron microscopy-derived structural data result in integrative methodologies with new capabilities for structural biology.","PeriodicalId":93,"journal":{"name":"Nanoscale Horizons","volume":" ","pages":"2570-2581"},"PeriodicalIF":6.4,"publicationDate":"2026-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13418849/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148617606","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}

In this study, we investigate the effect of daunomycin intercalation on DNA stability and charge transport. We employ a combination of classical molecular dynamics simulations, electronic structure calculations, and charge transport within the Landauer-Büttiker framework. The intercalation significantly enhances DNA rigidity, with bis-daunomycin providing further stabilization due to the linker. The results show that the bis-daunomycin intercalation enhances conductance by nearly threefold, despite the presence of a non-conjugated linker. The conductance enhancement arises from the cooperative interplay of linker-induced structural stabilization and intercalator-derived electronic states, with structural stabilization providing the dominant differentiating factor. Additionally, intercalation introduces daunomycin-derived states near the LUMO region, leading to a reduction in the HOMO-LUMO gap from 4.22 eV to 2.23 eV. These findings highlight the importance of structural stabilization in tuning quantum transport properties and suggest the potential of bis-intercalators for DNA-based nanoelectronic applications.","PeriodicalId":93,"journal":{"name":"Nanoscale Horizons","volume":" ","pages":"2593-2601"},"PeriodicalIF":6.4,"publicationDate":"2026-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148676136","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}

They are nanoscale, mosaic, dynamically reorganizing layers shaped by a Na+ solvation sheath, electrical double layer, and chemo-mechanical environment that differ markedly from Li+ analogs. This article reframes Na-ion interphase design around three linked ideas: (i) the primary Na+ solvation sheath, not the bulk electrolyte-stability window, selects first-layer chemistry at the nanoscale, through adsorption, desolvation and absorption at the electrode surface; (ii) under lean electrolyte and practical negative-to-positive (N/P) ratios, both interphases co-evolve through cross-talk rather than as independent passivation layers; and (iii) credible mechanistic claims require an explicit evidence-tier hierarchy and minimum reporting set.

Graphene oxide (GO), a pivotal derivative of graphene, exhibits immense potential for multifunctional nanocomposites, attributed to its unique 2D framework, abundant surface functional groups, and excellent solution processability. This review establishes structural engineering as the foundational paradigm for designing graphene-based nanocomposites with integrated multifunctionality. We systematically examine how structural engineering governs multiscale architectures from atomic-level defect configurations to macroscopic assembly geometries and elucidate the underlying structure-property relationships through mechanistic frameworks including phonon transport theory, percolation theory, and composite micromechanics. In-depth analyses of multifunctional applications in mechanical engineering, electronics, energy storage, environmental remediation, and biomedicine are presented, with explicit attention to both demonstrated advantages and persistent limitations of each application category. Critically, we identify and analyze four key industrialization bottlenecks, including structural controllability, batch consistency, scale effects, and cost-effectiveness trade-offs that currently impede the transition from laboratory achievements to scalable manufacturing.

The results demonstrate that the monolayer MoS3 exhibits excellent structural and thermal stability, narrow-bandgap semiconductor behavior, high carrier mobility, and pronounced mechanical anisotropy, highlighting its potential for applications in flexible electronics. Building upon this foundation, we designed a series of single-atom catalysts by anchoring transition metal atoms at distinct sulfur coordination sites (S1, S2, S3) of the MoS3 support. This work reveals that both the dopant element and its coordination site precisely regulate the catalytic activity and selectivity for the CO2 reduction reaction (CO2RR). Theoretical screening identified three highly promising candidates: ScS2@MoS3, ScS3@MoS3, and NiS3@MoS3. ScS2@MoS3 favors the formate pathway to HCOOH with a low limiting potential of -0.18 V. ScS3@MoS3 exclusively produces CH3OH with a rate-determining step of *CHO → *OCHH (UL = -0.58 V). NiS3@MoS3 can generate both HCOOH (UL = -0.55 V) and CH3OH (UL = -0.72 V) under different potentials. Notably, ScS3@MoS3 exhibits the lowest reaction energy for methanol formation. This study provides crucial theoretical guidance for developing efficient and tunable CO2 electrocatalysts and expands the Mo-S material family by introducing a metastable but accessible 2D MoS3 platform with unique coordination environments for single-atom catalysis, thereby broadening the application potential of 2D materials in energy conversion and environmental remediation.","PeriodicalId":93,"journal":{"name":"Nanoscale Horizons","volume":" ","pages":"2637-2653"},"PeriodicalIF":6.4,"publicationDate":"2026-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148838587","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}

We demonstrate that the rigid POSS scaffold creates excess free volume, reduces compressibility and thermal expansion, and introduces reversible shear-thinning viscoelasticity while maintaining efficient ion conduction. Furthermore, our high-pressure experiments reveal that ion dynamics is mostly thermally activated in this nano-hybrid electrolyte and satisfies the density-scaling concept, enabling accurate prediction of ionic conductivity over 12 decades across a wide T-P landscape.

Although short-channel drain current (ID)-gate voltage characteristics can often be described accurately within transport-based formalisms, the corresponding gm commonly exhibits pronounced low-temperature anomalies that remain unexplained. Here, we investigate a 65 nm Si n-channel transistor measured from 250 K down to 12 K and show that a Landauer-consistent model provides an accurate quasi-ballistic transport baseline for the ID across the full temperature range, but fails to reproduce the shoulder-like gm feature that emerges at deep cryogenic temperature. We show that this residual discrepancy originates not from transport nonidealities but from quantum capacitance (Cq)-induced electrostatic renormalization of gate-induced charge modulation. By decomposing the gm into transport and charge-response contributions, and introducing a gate-control factor governed primarily by the Cq, we derive a compact framework in which the corrected gm consists of renormalized baseline and differential electrostatic terms. A two-crossover parameterization of Cq in the effective gate-overdrive domain enables simultaneous and self-consistent reproduction of both the ID and gm, including the cryogenic shoulder. These results identify anomalous cryogenic gm as a Cq-induced signature of rapidly varying gate-to-charge coupling in quasi-ballistic transistors.","PeriodicalId":93,"journal":{"name":"Nanoscale Horizons","volume":" ","pages":"2548-2559"},"PeriodicalIF":6.4,"publicationDate":"2026-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148519549","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}
