Silver NPs are silver oxide dominated. This review addresses the green synthesis of Ag₂ONPs utilizing <em>Bt</em> and its chitinase enzyme. Here we are emphasizing the unique physicochemical and bioactive characteristics that position these nanoparticles at the forefront of next-generation biopesticides. <em>Bt</em>-Ag₂ONPs combine the entomopathogenic potency of <em>Bt</em> with the oxidative and antimicrobial properties of silver, yielding dual-action nanoconjugates that demonstrate enhanced insecticidal activity, reduced pupal emergence, and broad-spectrum efficacy against agricultural pest insects. <em>Bt</em>-Ag₂ONPs demonstrated significantly higher insecticidal efficacy against <em>Tribolium castaneum</em> compared to <em>Bt</em> alone or commercial Ag₂ONPs. These nanoparticles also markedly suppressed pupal emergence, underscoring their potent developmental inhibition effects. Furthermore, the biosynthesis process is environmentally benign, cost-effective, and highly tunable, allowing for control over nanoparticle size, dispersity, and stability. There are several limitations about their ecotoxicology and regulations that are discussed in this review. The review also addresses current trends in formulation science, including smart delivery systems and precision-targeted applications as well as future research directions in synthetic biology and ecotoxicological assessment. <em>Bt</em>-derived Ag₂ONPs represent a powerful, multifaceted tool for integrated pest management strategies, offering a compelling alternative to conventional chemical pesticides and laying the groundwork for more resilient and sustainable agroecosystems.</div></div>","PeriodicalId":36919,"journal":{"name":"Results in Engineering","volume":"28 ","pages":"Article 107156"},"PeriodicalIF":7.9,"publicationDate":"2025-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145047287","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}

This approach leverages the established correlation between drive torque fluctuations and wear progression observed during testing. Utilizing Symmetrized Dot Pattern (SDP) transformation, one-dimensional torque signals are converted into two-dimensional images for enhanced feature characterization. Torque signals spanning the complete service-life cycle at distinct wear stages were acquired to develop a YOLO11-CLS-based wear classification model. By monitoring torque variations during gear meshing in real-time, the method achieves wear staging and failure diagnosis. Experimental results demonstrate significant morphological differences in Polyamide (PA) gear debris across operating conditions: lower parameters produce finer, more uniform debris. PA gear wear evolution follows a distinct three-stage process (running-in → stable wear → severe wear), with torque signals enabling stage differentiation at &gt;96 % classification accuracy. The method provides effective failure diagnosis for PA gears while offering practical implementation advantages.

However, traditional forecasting methods often struggle either due to ineffective data preprocessing or due to a poor feature extraction and selection process, resulting in reduced accuracy. To address the mentioned issues, this research work introduces a novel Dynamic Temporal Interaction and Feature Synthesis (DTIFS) solar power-forecasting framework. The proposed framework utilizes advanced feature engineering techniques such as interaction terms, polynomial transformations, lagged features, and categorical binning to improve prediction accuracy significantly. A detailed exploratory data analysis (EDA) is conducted, and an intelligent feature engineering process is carried out on the acquired dataset, which led to a significant improvement in the model’s prediction accuracy. To assess the performance of the developed framework, several Machine Learning (ML) and Deep learning (DL) models are applied and tested based on several well-known performance evaluation metrics such as mean absolute error (MAE), root mean square error (RMSE) and R². It was found that the Random Forest (RF) model had an MAE of 15.32, an RMSE of 17.90, and an R² of 0.95 without the proposed framework. However, after applying the novel DTIFS framework, the Multilayer Perceptron (MLP) model outperformed, reaching an MAE of 9.281, RMSE of 12.453, and an R² of 0.98, thus outperforming its competing models under identical operating conditions. This study highlights the crucial role of advanced data transformations in enhancing solar power forecasting models, improving accuracy, and facilitating the integration of renewable energy into the grid. The DTIFS framework demonstrates its effectiveness compared to other advanced models, such as RNN, LSTM, and GAN, positioning it as a promising tool for future solar energy forecasting applications.</div></div>","PeriodicalId":36919,"journal":{"name":"Results in Engineering","volume":"28 ","pages":"Article 107140"},"PeriodicalIF":7.9,"publicationDate":"2025-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145027159","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}

Through integrated full-scale field experiments and ANSYS/LS-DYNA simulations, this study systematically investigates (1) dynamic response patterns and (2) safety thresholds for RC pipelines subjected to rockfall impacts. Field testing revealed two key phenomena: localized residual stresses develop in soil near impact zones, while horizontal-dominated soil vibrations induce circumferential strain concentration in pipeline mid-sections. Numerical modeling further uncovered diameter-dependent mechanical responses: peak particle velocities concentrate at pipe waists, whereas maximum principal strains and stresses localize at crown and invert positions, respectively. By correlating tensile stress criteria with energy-impact relationships, we established critical collapse thresholds for Groove-and-Tongue (GT) RC pipelines (90–135 cm inner diameters) under rockfall impacts ranging from 0.1 to 1 m³.
