Understanding of these processes requires the analysis of key parameters, including time, heat flux, particle size, velocity, excess air ratio, furnace temperature, heat load, and oxide concentrations, with a particular focus on deposition thickness. Traditional methods often fail to capture the complexity of these interactions, necessitating innovative approaches for accurate prediction and analysis. The experimental data, along with four algorithms, i.e. Support Vector Regression (SVR), Random Forest (RF), Deep Neural Network (DNN), and Extreme Gradient Boosting (XGBoost), were employed to analyze 20 features, providing a robust evaluation of their predictive capabilities. Furthermore, the use of SHAP (SHapley Additive Explanations) values introduces a novel dimension to the study, enabling interpretability and transparency in understanding the contribution of each feature to the model's predictions. The results demonstrate exceptional predictive accuracy for the RF and XGBoost models, achieving an R<sup>2</sup> value of 0.99 and minimal mean absolute errors (MAE). A novel comparison of training times reveals that SVR outperforms the other algorithms in speed due to its simpler structure, making it highly efficient for real-time applications. Correlation analysis identifies strong relationships between deposition thickness and key parameters such as time, heat flux, and deposition probability at varying surface temperatures. Time directly influences deposition thickness, as particles accumulate and sinter over prolonged operation. Heat flux drives particle movement through thermophoresis, affecting surface adhesion and increasing deposition probability. Surface temperature modulates particle adhesion and slag viscosity, with optimal temperatures maximizing stickiness and deposition probability.</div></div>","PeriodicalId":401,"journal":{"name":"Particuology","volume":"103 ","pages":"Pages 41-54"},"PeriodicalIF":4.1,"publicationDate":"2025-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144170519","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}

The process of applying four coating layers on high-density uranium dioxide kernel particles results in an increase in particle size and a decrease in density. Most existing coating models at the single-particle scale assume homogeneous coating under thin layer conditions, which makes it difficult to accurately describe the actual evolution process of coated particles preparation. Therefore, this study proposed a particle-binding-type heterogeneous layer (PBT-HL) model combined the binding concept with the CFD-DEM method, which accounts for dynamic changes in the density of coated particles. Then model validation in terms of gas-solid interaction and mass transfer, and coating condition parameter analysis were given at first. The results showed that changes in operational parameters such as the layer density, loading capacity, and inlet gas velocity can affect the spouted fluidization state, further influencing the deposition rate and coating effectiveness. These findings also suggested that the heterogeneous coating model in binding configuration can be further developed to study the anisotropy of single-particle layer thickness quantitatively. In summary, the variable-density PBT-HL model approximates the actual coating layer preparation process more closely, aiding in the acquisition of coating process information and guiding the optimization of coating techniques. The proposed heterogeneous coating model also holds potential for further development to characterize the intra-particle uniformity and the conformality feature of FB-CVD technique in the future.</div></div>","PeriodicalId":401,"journal":{"name":"Particuology","volume":"103 ","pages":"Pages 1-17"},"PeriodicalIF":4.1,"publicationDate":"2025-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144155119","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}

Induced nucleation influences crystal growth by modulating parameters such as temperature and solvents, while in situ nucleation controls the process through the introduction of specific precursors. Seed-mediated growth, on the other hand, involves the growth of crystals on pre-existing seeds supported on substrates. By leveraging the significant advantages of MOF composites, such as enhanced conductivity, stability, and performance, these materials have been shown to improve the functionality of supercapacitors and batteries. Additionally, they exhibit excellent catalytic activity in electrocatalysis.
