To aid in the engineering and design of these components, a thorough understanding of the thermal behavior of these inhomogeneous and often highly anisotropic materials is essential, particularly in terms of their coefficient of thermal expansion (CTE). To explore this, the authors produced magnetic composites using compression molding and casting techniques. The epoxy polymer matrix was modified with a commercial thickening agent, and isotropic magnetic particles were added as functional fillers. The microstructural morphology of the composites, including the distribution, dispersion, and alignment of the magnetic fillers, was analyzed through microscopy techniques like scanning electron microscopy. Furthermore, the glass transition temperature of both the polymer matrix and the composites was measured using differential scanning calorimetry (DSC). The CTEs of both the polymer matrix and the composites were experimentally determined using a custom-designed setup and analyzed through stochastic finite element analysis (SFEA). Five modeling scenarios were considered to predict the CTEs of the composite systems: fully random distribution, randomly aligned distribution, a ‘bonded’ interface contact, and a ‘no-separation’ interface contact for the in-plane directions of particles. For the out-of-plane direction, the randomly aligned distribution with ‘no-separation’ contact was also explored. Among the in-plane direction scenarios, the case with ‘bonded’ interface contact and randomly aligned distribution yielded the lowest CTE, while the case with fully random distribution and ‘no-separation’ interface contact resulted in the highest CTE.

This paper explores the optical and electrical properties of GQDs with a particular focus on the impact of Pt and Pd dopants on the spectral characteristics of GQDs, emphasizing their role in enhancing adsorption energies and gas selectivity. Our findings indicate that the most favorable doping site within the GQDs structure is the center of a carbon hexagon (hollow site, H). The adsorption energy of NO₂ on pristine GQDs at the top site (T) is determined to be −0.16 eV, while doping with Pt and Pd significantly increases this value to approximately −2.0 eV. Additionally, charge transfer calculations reveal that in Pt-GQDs, −0.562e is transferred from the GQDs to the transition metal, whereas in Pd-GQDs, the transferred charge is −0.203e. The most favorable adsorption configurations for NO₂ and H₂O on Pd-, Pt-doped, and pristine GQDs correspond to the O and H orientations, respectively. A significant shift in the Fermi level toward the conduction band is observed upon NO₂ adsorption, whereas the effect is minimal for H₂O. The results demonstrate that Pt and Pd-doped GQDs exhibit higher adsorption energies, indicating their impact in gas-sensing applications. Pd-doped GQDs show stronger sensitivity to NO₂, which makes it a promising candidate for efficient gas detection. Optical analysis reveals a blue shift in the absorption peaks around 18 eV, providing insights into electronic transitions induced by gas interactions. Furthermore, in Pt- and Pd-doped GQDs, new absorption peaks emerge in the low-energy range (2–5 eV), indicating they are suitable for gas sensing applications within this region of the electromagnetic spectrum.</div></div>","PeriodicalId":21042,"journal":{"name":"Results in Physics","volume":"74 ","pages":"Article 108311"},"PeriodicalIF":4.4,"publicationDate":"2025-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144139607","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The approach involves constructing a physical point cloud from inter-particle stress information extracted from randomly distributed colloidal particles and embedding it into a graph convolutional network (GCN). In the field of pattern recognition, GCNs are widely utilized to classify arbitrary 3D objects by learning multidimensional relationships within feature spaces defined by spatial coordinates. In contrast, our study constructs a feature space based on the micromechanical stresses imparted on colloidal particles during their self-assembly, rather than relying on spatial information. This enables predictive functionality within the classification task. Using this method, we discover for the first time that the convolution of canonical physical information can predict the self-assembly of colloids by observing only the initial configurations of colloidal particles, whereas conventional pattern recognition techniques using spatial information could only recognize phase transitions near completion. The phases predicted by our model are not limited to liquid-like dispersions and solid–liquid phase separations, where thermodynamic equilibrium differs, but also include sample-spanning gel structures, where only kinetics differ while thermodynamics remain the same. Furthermore, although we train the semantic stress relationships that constitute each phase of the network using same-sized particles with a pre-specified inter-particle interaction, our algorithm demonstrates generalized predictive performance even for suspensions with randomly distributed particle sizes. Our results make it possible to predict the phase behavior of colloidal systems where traditional theoretical approaches have been challenging or impossible due to the inherent complexity of the colloidal system. Given that colloids are characterized by extremely small length scales, long times are required for observable macroscopic changes resulting from self-assembly. Therefore, this study is expected to serve as a highly useful decision-support method for engineering soft matter with desired morphologies.</div></div>","PeriodicalId":21042,"journal":{"name":"Results in Physics","volume":"74 ","pages":"Article 108296"},"PeriodicalIF":4.4,"publicationDate":"2025-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144115153","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The main goal of this study is to develop an effective numerical method to identify the optimal frequency in Rayleigh-Plateau instability. First, the numerical results are validated with experimental data. Then, a systematic method for calculating the optimal frequency using simulated data and the discrete Fourier transform (DFT) is proposed.
