This study focuses on the predicting the Marshall Stability of plastic-reinforced asphalt concrete using machine learning algorithms. Machine learning algorithms, including Random Forest (RF), Gradient Boosting, Extreme Gradient Boosting (XGB), and Bagging Regressor (BR) were employed to predict the Marshall Stability. The machine learning models were evaluated using six performance metrics, including coefficient of correlation (R), root mean square error (RMSE), mean absolute error (MAE), relative absolute error (RAE), root relative squared error (RRSE), mean absolute percentage error (MAPE), and scatter index (SI), to ensure robust and reliable predictions. Additionally, SHapley Additive exPlanations (SHAP) analysis was conducted to perform a parametric identifying the influence of input parameters on Marshall Stability. Specifically, the XGB model achieved the best R values of 0.95 for training and 0.84 for testing, indicating strong correlations between predicted and actual MS values. Furthermore, SHAP analysis was conducted for the XGB model, which highlighted the significant influence of plastic size and bitumen content on MS prediction. SHAP and machine learning models can be used to optimize the composition of plastic-reinforced asphalt concrete for enhanced performance and sustainability. This research will provide practical guidance for pavement engineers and policymakers in utilizing waste plastic for sustainable infrastructure development.</div></div>","PeriodicalId":100614,"journal":{"name":"Hybrid Advances","volume":"10 ","pages":"Article 100483"},"PeriodicalIF":0.0,"publicationDate":"2025-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143823333","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Properties such as lightweight, sustainability, design flexibility, microstructure, durability, and advanced fabrication techniques have expanded their use across industries. Also, NFRCs are preferred because the extensive reliance on synthetic fibers presents significant challenges in recycling and waste management. Despite their excellent properties, NFRCs have three main challenges: fiber degradation, water degradation, and weak interfacial strength (incompatibility of fibers with the matrix). Consequently, research efforts have been directed at combating these challenges using different surface treatment techniques. However, research has been skewed towards experimental approaches for improving the interfacial strength in plant fiber polymer matrix composites (PMCs). Hence, there exists a dearth of information on the computational approaches for optimizing the interfacial properties of NFRCs. Hence, this review provides experimental and computational approaches (machine learning) for comprehensive optimizing strategies for different natural fibers (plant, animal, and microorganism) and matrices (polymers, metals, and ceramics). This review also highlights the importance of theoretical approaches and numerical modeling in analyzing and optimizing NFRCs.

Consequently, the rise in personal and commercial vehicle use has significantly contributed to the growing accumulation of scrap tires. Landfilling of waste tires in open mounds causes issues such as the spread of mosquito-borne diseases and landscape degradation. On the other hand, open burning of the tires is difficult as the subsequent fire extinguishing consumes many resources. Furthermore, there are concerns regarding fire safety and releasing harmful toxic gases into the air. Besides, the tire waste construction industry uses a lot of natural resources, such as sand, which are depleting. To avoid the depletion or scarcity of these natural resources, it is necessary to use alternative materials instead of sand. Indeed, methods to reuse or recycle tire waste must be devised. Research has started to explore the potential of using tire waste in the crumb rubber form, which is a waste product derived from the recycling of tires, as a partial substitute for fine aggregate in concrete. This review study aims to find the effect of crumb rubber (CR) in normal concrete as a partial replacement for sand. The study's objective is to provide a baseline for the effect of CR on normal concrete to provide a pathway for future studies working on rubber concrete to mitigate the limitations of the use of CR in concrete. A systematic meta-analysis is performed on the experimental facts from different studies to develop a model for optimizing the use of CR in concrete. The regression model adopted showed a good variation with the input data. The study finds that adding CR to concrete leads to a loss in its mechanical properties when crumb rubber is used. Despite the decrease in strength, rubberized concrete demonstrates enhanced durability characteristics, such as greater resistance to acid attack and chloride ion penetration, making it well-suited for environments with high chlorine exposure. This article provides an overview of the use of crumb rubber as an alternative substitute for fine aggregate in concrete and reviews the normal concrete's properties based on the research findings thus far.</div></div>","PeriodicalId":100614,"journal":{"name":"Hybrid Advances","volume":"10 ","pages":"Article 100481"},"PeriodicalIF":0.0,"publicationDate":"2025-04-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143800589","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among different semiconducting materials, gallium arsenide (GaAs) is the second most prominent materials for developing devices due to its direct band gap and high electron mobility. In this work, the geometric, electronic, and thermodynamic properties of the GaAs nanodot after consecutive doping with homogenous transition metals (Ir–Ir) and heterogeneous transition metals (Ir–Ru &amp; Ir–Pd) have been investigated. The investigation has been performed by employing density functional theory (DFT) with B3LYP hybrid functional using LanL2DZ basis set. The investigation reveals that the GaAs nanodot gains more stability (−98 eV ∼ −468 eV for doped clusters and −21 eV for the pristine cluster) and becomes efficient which is confirmed by studying binding energy and bond lengths in the heterogeneous doping process rather than the sequential homogenous doping process. Moreover, the infrared (IR) spectra analysis confirms that all structures might be found naturally in a stable and true energy minima, except Ga₂As₂Ir₂Ru₂_, because of the presence of imaginary frequency. Also, the band gap (1.2 eV–2 eV for all doped structures) exhibits a suitable semiconducting nature of the doped structures. The thermodynamic properties show that both homogenous and heterogenous doping techniques cause thermodynamic stability to the GaAs nanodot as well as make them more feasible. Finally, considering all the physicochemical properties it has been concluded that for GaAs nanodot, the heterogenous atom doping process is more efficient than the homogenous atom doping when the dopant number is the same.</div></div>","PeriodicalId":100614,"journal":{"name":"Hybrid Advances","volume":"10 ","pages":"Article 100482"},"PeriodicalIF":0.0,"publicationDate":"2025-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143800588","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The acidic and basic properties of the catalysts were quantitatively assessed through potentiometric titration, confirming the presence of both acid and basic sites, which are essential for the concurrent esterification of free fatty acids (FFAs) and transesterification of triglycerides. This bifunctionality is particularly advantageous for feedstocks with high FFA content, such as waste cooking oil, addressing a key challenge in biodiesel synthesis. The SrO-based catalyst demonstrated exceptional performance, achieving yields of 96 % for corn oil and 93 % for waste cooking oil, with minimal yield differences of 3 % attributed to the latter's impurities and higher FFA content.
