The bibliometric study collected and analyzed 1860 documents from the SCOPUS database published between 2014 and 2024. Keyword analysis highlights terms like \"antioxidants\" and \"feedstocks\", including fats and oils, plant seeds, and plant extracts, emphasizing the critical role of feedstock types as principal drivers for initiating oxidation reactions. A co-country analysis identified \"China\" and \"India\" as top contributors, with 11,653 and 9298 citations, respectively, showcasing their strong research commitment to sustainable bioenergy. \"Chemical Reviews\" was tabled as the most-cited journal (4396 citations) and \"Yaakob et al., 2014\" as the most-cited author (449 citations) within the review period, underscoring the researchers’ active involvement in the field. While natural antioxidants have demonstrated superior antioxidative potential compared to their synthetic counterparts owing to greater solubility, lower cost, and higher potency at lower concentrations, their efficacy can be further enhanced through synergistic combinations. In contrast, the application of nanotechnology-based antioxidants in biodiesel stabilization remains in its infancy, presenting promising opportunities for further exploration. Finally, this study offers valuable insights into research trends, existing gaps, and future directions for researchers, policymakers, and industry stakeholders committed to enhancing biodiesel stability and advancing sustainable energy solutions.</div></div>","PeriodicalId":36919,"journal":{"name":"Results in Engineering","volume":"26 ","pages":"Article 105185"},"PeriodicalIF":6.0,"publicationDate":"2025-05-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143928931","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}

Traditional water quality monitoring relies on manual sampling and laboratory analysis, which are often costly, time-intensive, and lack real-time insights. This review critically examines the integration of machine learning (ML) and the internet of things (IoT) for real-time water quality monitoring and predictive analytics. The study evaluates peer-reviewed research published between 2016 and 2024, focusing on advancements, limitations, and future trends in automated water quality assessment. ML models, including random forest, extreme gradient boosting, support vector machines, and neural networks, have been more frequently used in water quality research and have achieved high accuracies (R²=0.99 in regression and 0.99 accuracy metric in classification). Explainable AI (XAI) which can explain the decision making process of ML, is underutilised, appearing in only a few recent studies. While IoT significantly improves real-time contamination detection, persistent challenges remain in sensor fouling, data continuity, data privacy, network reliability, and cybersecurity. Such challenges can hinder the scalability and effectiveness of long-term IoT implementations. Integrating IoT with machine learning enhances water quality monitoring by enabling real-time data collection, remote tracking, and predictive analytics. This synergy improves efficiency, addresses monitoring challenges, and supports sustainable water management.</div></div>","PeriodicalId":36919,"journal":{"name":"Results in Engineering","volume":"26 ","pages":"Article 105182"},"PeriodicalIF":6.0,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143917568","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}

Notwithstanding its elevated capacity factor (&gt;85 %), nuclear energy presently accounts for a mere 3 % of the nation's electricity generation as of 2024. The investigation presents a thorough evaluation of India’s nuclear infrastructure, which comprises 22 operational reactors (6780 MW) and strategic initiatives aimed at augmenting capacity to 22,480 MW by 2031. The study accentuates pivotal technological innovations such as Fast Breeder Reactors (FBRs), small modular reactors (SMRs), and the utilization of India’s vast thorium reserves (846,000 tonnes) as integral components of the three-stage nuclear program. It further analyzes obstacles, including constraints on the supply of uranium, rigorous regulatory frameworks, and societal opposition. Through an international comparative analysis and policy assessment, this research delineates pathways for the enhancement of nuclear development, encompassing regulatory reforms, public engagement strategies, increased investment in research and development (R&amp;D), participation from the private sector, and fostering global collaboration.
