While the synthesis of AuNS with HEPES overcomes these limitations by using a biocompatible buffer that acts as both a shape-directing and a reducing agent, the resulting nanoparticles are highly heterogeneous and polydisperse. In this paper, we use a microfluidic chip to manipulate the morphology and optical properties of AuNS, while significantly improving their monodispersity. Notably, by adjusting microfluidic parameters, including viscosity of the organic phase, flow rate ratio, and buffer-to-gold ratio, this protocol can manipulate the growth mechanism of the nanoparticles, switching between seedless and seed-mediated-like growth, and it does so without the need to add a presynthesized seed. Such control is not possible with one-pot bench synthesis.

This method is particularly significant in the study of chromium trichloride (CrCl<sub>3</sub>), a material that has garnered considerable attention due to its unique magnetic behavior. In this study, by considering only the nearest neighbor exchange interactions, we systematically investigated the magnetic Raman response of 2D CrCl<sub>3</sub> and observed a notable frequency shift of approximately 20 cm<sup>–1</sup> in the E<sub>g</sub><sup>2</sup> Raman peak across different magnetic configurations. This shift is primarily attributed to spin–phonon coupling, thereby providing a reliable means to distinguish between various magnetic configurations. The E<sub>g</sub><sup>2</sup> Raman peak is associated with the collective vibrations of Cr and Cl atoms, with Cr atoms playing a dominant role in the observed differences between magnetic configurations. Even when considering more complex magnetic configurations, such as including next-nearest and third-nearest neighbor interactions, nearest neighbor exchange interactions remain the most significant. This predominance allows the E<sub>g</sub><sup>2</sup> peak to be effectively interpreted as a superposition of simpler magnetic configurations. Additionally, we explored the effects of external strain and carrier doping on the Raman spectrum of 2D CrCl<sub>3</sub>. Under external biaxial strain, the E<sub>g</sub><sup>2</sup> peak exhibits anomalous frequency shifts. Electron doping significantly influences the Raman spectra, whereas hole doping has only minimal effects. Importantly, the in-plane spin–phonon coupling remains largely unaffected by variations in crystal thickness, crystal phase, or interlayer magnetic interactions. These findings enhance our understanding of the intrinsic spin–phonon coupling in CrCl<sub>3</sub> and establish a robust foundation for exploring and engineering the magnetic properties of 2D materials.","PeriodicalId":61,"journal":{"name":"The Journal of Physical Chemistry C","volume":"125 1","pages":""},"PeriodicalIF":4.126,"publicationDate":"2025-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144066128","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Traditional methods of predicting gas selectivity across broad pressure, temperature, and composition (PTX) conditions face considerable computational demands, particularly when simulating both adsorption and diffusion in porous materials. We tackled this challenge by integrating Gaussian Process (GP) models with grand canonical Monte Carlo (GCMC) and molecular dynamics (MD) simulations, applying AL to iteratively select data points exclusively based on the highest model uncertainty (emphasizing exploration), and others schemes, to systematically improve prediction accuracy across diverse conditions. We evaluated several AL strategies tailored to two distinct molecular-level phenomena involved in gas separations: adsorption and diffusion. Specifically, adsorption-based selectivity prediction methods employed AL to preferentially select data points characterized by high uncertainty in adsorption predictions. In contrast, diffusion-based selectivity prediction methods directed AL toward regions exhibiting high uncertainty in diffusion predictions. These approaches included direct prediction of selectivity as well as propagation-based methods, where selectivity uncertainty was calculated from individual component uncertainties in adsorption or diffusion predictions. The culmination of this exploration is an end-to-end (E2E) framework that integrates adsorption and diffusion modeling within a single AL-driven data-labeling process. In this framework, uncertainty in either adsorption or diffusion predictions guides data selection, enabling more precise model training across adsorption and diffusion. Results indicate that the diffusion-focused E2E scheme yields the highest predictive accuracy and a more efficient process. This approach minimizes redundant sampling and improves the efficiency of data acquisition across adsorption and diffusion models.","PeriodicalId":61,"journal":{"name":"The Journal of Physical Chemistry C","volume":"232 1","pages":""},"PeriodicalIF":4.126,"publicationDate":"2025-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144066121","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

TEM images reveal well-dispersed ZnO nanoparticles with sizes ranging from 5 to 20 nm, indicating a good compatibility between ZnO and PS. AFM analysis shows surface roughness variations with the height distribution ranging from 80 to 100 nm, aligning with the observed ZnO dispersion. XRD patterns confirm ZnO incorporation, with characteristic peaks at 31.71, 34.53, 36.26°, and others becoming more prominent with higher ZnO content. Thermal analysis reveals a clear dependence of peak temperature (<i>T</i><sub>p</sub>) on heating rate, with a notable increase in <i>T</i><sub>p</sub> from 430.5 to 457.6 °C as the heating rate increases from 20 to 30 °C/min. The Kissinger method shows activation energy values ranging from 59.16 to 55.77 kJ/mol, indicating stable thermal degradation, while the Arrhenius method yields slightly lower activation energies ranging from 37.85 to 39.84 kJ/mol, reflecting the material’s sensitivity to heating rate changes.

Moreover, the hybridization of the quantum dots does not show any lagging in the photoresponse of the WSe<sub>2</sub> devices. To explore the carrier migration in the hybrid structure, we investigated two mechanisms, namely, the direct charge transfer in the photogating effect and the exciton transfer mediated by the Förster resonance energy transfer (FRET) process. The time-resolved photoluminescence (TRPL) spectroscopy is used to analyze the proportion of these mechanisms. The results reveal that the FRET mechanism, which leads to a short fluorescence lifetime in TRPL, dominates the photoresponse in the device. As more layers of quantum dots are spin-coated on WSe<sub>2</sub>, the photogating effect, which corresponds to a longer fluorescence lifetime, becomes more manifested and consequently delays the photoresponse of the device. This study demonstrates a promising design of a photodetector that combines high responsivity with rapid response speed, through the introduction of quantum dots with high photo absorption, and the FRET mechanism in the heterostructure.","PeriodicalId":61,"journal":{"name":"The Journal of Physical Chemistry C","volume":"4 1","pages":""},"PeriodicalIF":4.126,"publicationDate":"2025-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144067320","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we show that in spatially extended nanostructures the lattice temperature can locally exceed that of the electrons, a seemingly counterintuitive transient effect, termed hereafter “temperature inversion” (<i>T</i><sub><i>p</i></sub> > <i>T</i><sub><i>e</i></sub>). This phenomenon, fundamentally due to inhomogeneous absorption patterns and absent in smaller particles, emerges from a complex spatiotemporal interplay between the electron–phonon coupling and competing electronic thermal diffusion. By combining rigorous three-dimensional (3D) finite-element-method-based simulations with practical reduced analytical models, we identify the electron–phonon coupling coefficient (<i>G</i><sub><i>e</i>–<i>p</i></sub>) as the critical parameter governing this behavior. An optimal <i>G</i><sub><i>e</i>–<i>p</i></sub> range allows inversion, whereas a weak or overly strong coupling suppresses it. Among common plasmonic metals, platinum exhibits the most pronounced and long-lived inversion, while gold and silver show no significant inversion. Moreover, the close agreement between the analytical model and 3D results, once an appropriate characteristic length is selected, highlights that the essential physics governing the inversion can be captured without full spatial complexity. These results provide insights for optimizing nanoscale energy transfer and hot-carrier-driven processes, guiding the strategic design of materials, geometries, and excitation conditions for enhanced ultrafast photothermal control.","PeriodicalId":61,"journal":{"name":"The Journal of Physical Chemistry C","volume":"30 1","pages":""},"PeriodicalIF":4.126,"publicationDate":"2025-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144000626","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
