The accurate prediction and classification of bandgaps in these materials are crucial for advancing their technological potential. Traditional methods like Density Functional Theory (DFT) are computationally expensive, motivating the use of machine learning (ML) as a faster and more efficient alternative. In this study, we analyze 7382 hybrid and inorganic HP using a diverse set of ML models to classify materials based on whether they exhibit zero or nonzero bandgaps, and to predict their bandgap values. For regression tasks, AdaBoost Regressor (ABR), decision tree regressor (DTR), and gradient boosting regressor (GBR) were employed, while gradient boosting machines (GBM), decision tree (DT), and Multilayer Perceptron (MLP) were used for classification. Evaluation metrics for prediction included mean absolute error (MAE), mean squared error (MSE), and the <i>R</i>². For classification, metrics, such as accuracy, precision, recall, F1-score, area under the ROC curve (AUC-ROC), and area under the precision-recall curve (AUC-PR) were utilized. Results indicate that ABR achieved the highest prediction accuracy (MSE ≈ 0.074 eV, MAE ≈ 0.088 eV, <i>R</i>² ≈ 91.1% for direct bandgaps; MSE ≈ 0.041 eV, MAE ≈ 0.076 eV, <i>R</i>² ≈ 93.4% for indirect bandgaps). In classification, the GBM model outperformed others, achieving 96% and 97% accuracy for direct and indirect bandgaps, respectively. Feature analysis revealed that elemental properties, such as valence and group of constituent elements, particularly their mean and standard deviation, play a dominant role in bandgap determination. These findings highlight the potential of ML-driven approaches in accelerating perovskite material discovery and optimizing their electronic properties for future optoelectronic applications.</p>\u0000 </div>","PeriodicalId":14051,"journal":{"name":"International Journal of Energy Research","volume":"2025 1","pages":""},"PeriodicalIF":4.3,"publicationDate":"2025-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1155/er/1215175","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144714955","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study explored the conversion of food waste (FW) biomass into hydrochar achieved via hydrothermal carbonization (HTC) technology. The research focused on evaluating the merits and demerits of using mixed FW feedstock, especially rice, potatoes, vegetables, and/or animal byproducts such as meat and fish at varying water-to-biomass ratios and through the implementation of water recirculation in the HTC process. This approach aimed to decrease water consumption while assessing its impact on the fuel characteristics of the resultant hydrochar. The hydrochar produced demonstrated an enhanced carbon content, which is conducive to combustion, while also exhibiting improved fuel properties such as elevated heating values, improved energy densities, and reduced volatile components. Conditions exceeding 200°C, with a reaction time of 6 h, were found to be sufficient to attain an average carbon content of above 70% and a heating value of around 30 MJ/kg. Moreover, decreasing the water-to-biomass ratio enabled a reduction in initial water usage by up to 50%, without significantly impairing the carbon content and fuel attributes of the hydrochar. Thermogravimetric analysis (TGA) indicated a comparatively elevated combustion temperature of 600°C for the hydrochar generated at an HTC temperature of 220°C, which corresponded with a substantial increase in the carbon content of hydrochar up to 70.65% from initial 48% in the parent biomass. Consequently, the hydrochar generated from FW under different HTC reaction conditions, including water volume reduction and recirculation, demonstrated the potential for minimal water consumption.

Using a newly developed analysis platform, three transient conditions including the load reduction, reactivity insertion, and loss of heat sink were discussed. The results indicate that, with the intermediate heat storage, the micro nuclear energy system has better tolerance of the transient thermal shocks.

In recent decades, the crucial role of graphite (Gt) as the primary material for LIB anodes has been established. Although extensive research has been conducted to find alternatives with higher power and energy densities, Gt continues to be selected as the predominant material for commercial LIBs. During the operation of LIBs, the Gt reacts with the electrolyte to form a solid–electrolyte interphase (SEI). This complex and structurally disordered SEI layer acts as a barrier that suppresses undesirable reactions but also increases resistance, which in turn affects the LIB performance. Ionic liquids (ILs) are providing a promising solution for improving LIB performance owing to their nonflammability, low vapor pressure, tunability, and large electrochemical window. In this study, we examined the functionalization of Gt edges by employing 4-bromobenzoic acid (4BAc) via a direct Friedel–Crafts acylation reaction in a polyphosphoric acid (PPA)/phosphorous pentoxide (P&lt;sub&gt;2&lt;/sub&gt;O&lt;sub&gt;5&lt;/sub&gt;) medium. Additionally, we investigated the attachment of IL monomers to modified Gt to control the SEI layer formation. Our research findings demonstrated that IL-modified Gt exhibit significantly improved electrochemical cycle stability and durability, effectively addressing the capacity degradation and limitations of conventional Gt anodes “to” LIBs, indispensable in modern life, owe their ubiquity to their high energy density, rechargeability, and optimal power performance. Among anode materials, Gt has remained the cornerstone of commercial LIBs for decades due to its stability and cost-effectiveness. Despite extensive efforts to identify superior alternatives with enhanced power and energy densities, Gt’s dominance persists. However, during LIB operation, Gt reacts with electrolytes to form a structurally disordered SEI layer. While this layer prevents undesirable side reactions, it also increases resistance, thereby limiting LIB performance. In this study, we introduce a novel approach to address these challenges by functionalizing Gt edges using 4BAc via a direct Friedel–Crafts acylation reaction in a PPA/P&lt;sub&gt;2&lt;/sub&gt;O&lt;sub&gt;5&lt;/sub&gt; medium. Furthermore, IL monomers were grafted onto the modified Gt surface to regulate SEI layer formation. This dual-functionalization strategy uniquely leverages the nonflammability, tunability, and wide electrochemical window of ILs to enhance anode performance. Our findings reveal that IL-modified Gt significantly improves electrochemical cycle stability and durability, mitigating capacity degradation, and resistance issues associated with conventional Gt anodes.
