However, evaluating their flexural properties using conventional experimental techniques is time-consuming, costly, and limited by material and fabrication variations. This study investigates the potential of machine learning (ML) techniques to predict the flexural properties of fiber-reinforced composites accurately and efficiently. Five ML algorithms—Light gradient boosting regressor (LGBR), Extra tree regressor (ETR), Decision tree regressor (DTR), Histogram-based gradient boosting regressor (HGBR), and Adaptive boosting regressor (ABR)—were employed to predict the flexural strengths using both experimental data generated in-house and data collected from open literature. Including heterogeneous data from both sources enhances the robustness and generalizability of the developed models. The results demonstrate that the extra trees regressor (ETR) achieves excellent accuracy when applied to the heterogeneous dataset, with a coefficient of determination (R²) value of 0.94, MAE of 31.97, and RMSE of 47.64, outperforming the other three models. Furthermore, the in-house experimental data yields even higher prediction accuracy, with the best-performing model achieving an impressive R² value of 0.99, MAE of 9.53, and RMSE of 13.15. The high prediction accuracy achieved, despite the slight variability in data obtained from the literature, highlights the potential use of ML techniques to streamline the development process and reduce the reliance on extensive experimental testing. These robust models take into consideration important composite production parameters to provide design engineers and research scientists with versatile and efficient tools for the prediction of flexural properties of fiber-reinforced composites and related materials for various industries, including aerospace, defense, energy, biomedical and automotive.</div></div>","PeriodicalId":100614,"journal":{"name":"Hybrid Advances","volume":"8 ","pages":"Article 100385"},"PeriodicalIF":0.0,"publicationDate":"2025-01-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143161978","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}

PEG is added and contrasted with CS because it is hydrophilic in nature, non-toxic, antigenic, immunogenicity-free, and has a high level of biocompatibility. The produced scaffolds have undergone mechanical and thermal testing, biodegradability testing, FTIR analysis, and SEM analysis. The SEM pictures showed that the porous of PEG-PVC-2% SiO₂ provides a larger surface area to prevent corrosion when compared to neat PVC. It demonstrated PEGplasticized PVC scaffolds developed micropores as a result of PEG enrichment from the PVC matrix. FTIR analysis shows the presence of functional groups. The maximum stress is 16.5 MPa is found for neat PVC sample; while adding PEG and CS reduced the strength due to the plasticizing effects. Silica filler have been added to PVC and PEG scaffolds to enhance the strength. Though silica improved the mechanical strength of PVC-PEG scaffolds, still it is 10 MPa, close to neat one. According to thermogravimetric analysis (TGA), there is no discernible weight loss below 100 °C. PEG decreased the thermal stability of PVC, according to thermal analysis from the DSC plot.

The aim of the investigation was to study the level of photoprotection and the kinetics of release of photosensitive pharmaceutical ingredients (α-lipoic acid and moxifloxacin hydrochloride) encapsulated in halloysite nanotubes in the composition of the tablets. It was established that halloysite, like the widely used microcrystalline cellulose, meets a sufficient level in terms of fluidity and compressibility, which indicates the possibility of its use as an auxiliary component in the composition of pharmaceutical tablet forms. The physical and mechanical properties (disintegration, hardness, friability and abrasion tests, tensile strength) of the obtained tablet based on halloysite (45 %), microcrystalline cellulose (50 %) and auxiliary components (5 %) indicate their compliance with the standardized requirements of the European Pharmacopoeia. In the native state, the ingredients are almost completely released from the tablets within the first 60 min. Encapsulation in halloysite promotes their controlled release from tablets within 24 h. With a change in the pH of the model medium from 1.2 to 6.8, the level of release and dissolution of both pharmaceutical ingredients increases. In 24 h, the release level reaches 60–80 % for α-lipoic acid and 42–75 % for moxifloxacin hydrochloride. It was found that encapsulation in halloysite contributes to an increase in the photostability of pharmaceutical ingredients. The reduction in the effective concentration of ingredients encapsulated in halloysite after the photostability test is no more than 2–5 %. Thus, halloysite can be used in smart tablet formulations as an effective nanocarrier to enhance photostability and control release of pharmaceutical ingredients.</div></div>","PeriodicalId":100614,"journal":{"name":"Hybrid Advances","volume":"9 ","pages":"Article 100383"},"PeriodicalIF":0.0,"publicationDate":"2025-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143419628","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}
