“…Waste-cooking-oil-based biodiesel was best synthesized through an alkali-catalyst-based transesterification process. Through data analysis, it was proved that waste cooking oil could be used as an effective resource for biodiesel production along with lessening environmental pollution for society [ 1 , 18 , 19 ].…”

Biodiesel is considered a sustainable alternative to petro-diesel owing to several favorable characteristics. However, higher production costs, primarily due to the use of costly edible oils as raw materials, are a chief impediment to its pecuniary feasibility. Exploring non-edible oils as raw material for biodiesel is an attractive strategy that would address the economic constraints associated with biodiesel production. This research aims to optimize the reaction conditions for the production of biodiesel through an alkali-catalyzed transesterification of Tamarindus indica seed oil. The Taguchi method was applied to optimize performance parameters such as alcohol-to-oil molar ratio, catalyst amount, and reaction time. The fatty acid content of both oil and biodiesel was determined using gas chromatography. The optimized conditions of alcohol-to-oil molar ratio (6:1), catalyst (1.5% w/w), and reaction time 1 h afforded biodiesel with 93.5% yield. The most considerable contribution came from the molar ratio of alcohol to oil (75.9%) followed by the amount of catalyst (20.7%). In another case, alcohol to oil molar ratio (9:1), catalyst (1.5% w/w) and reaction time 1.5 h afforded biodiesel 82.5% yield. The fuel properties of Tamarindus indica methyl esters produced under ideal conditions were within ASTM D6751 biodiesel specified limits. Findings of the study indicate that Tamarindus indica may be chosen as a prospective and viable option for large-scale production of biodiesel, making it a substitute for petro-diesel.

“…Because of the global energy crisis, biodiesel has gained greater attention as an alternative energy source. Biodiesel is a kind of fuel produced via transesterification of oils derived from animals or plants yielding ethyl, methyl, or propyl ester [ 1 , 2 , 3 , 4 , 5 , 6 , 7 ].…”

“…[18][19][20] Moreover, azadirachtin, the major component of Neem oil, has been used against many pest arthropods, such as mites. 21 On another hand, due to its low mammalian toxicity, biodegradability, and broad-spectrum insecticidal action, Neem oil is considered a valuable substitute to synthetic pesticides, 22 while a lot of work has been conducted on Neem oil for renewable biodiesel production [23][24][25][26] and as environmental-benign innovative industrial anti-corrosive coatings. 27,28 Today, the scourge and fatalities caused by the virulent Covid-19 pandemic in Africa are relatively lower than those recorded in developed continents.…”

Prominent amongst these ethnobotanicals is Azadirachta indica A. Juss (Neem) which has been used for more than 2000 years in India and neighbouring countries due to its medicinal, insecticidal, biological pest control and landscaping potentials. 5 Today, Neem trees have been domesticated in about 72 countries in Africa, Asia as well as Central-and South America. 6 Various Neem extracts are profoundly utilized in Indian folk medicines, and these extracts are prepared as decoctions, infusions, poultices or pounded pastes to be administered as recommended. 7,8 Neem is classified under Meliaceae, which originated from the Indian sub-continent. 9 Other plants of the Meliaceae family, such as Carapa procera, Melia azaderach, Khaya senegalensis, and Trichilia emetic, are also well known for their repellent and insecticidal effects. 10 Neem is a perennial, mediumsized, fast-growing tree which naturally withstands harsh weather conditions and thrives even on poor soils, 6 while the oval-shaped fruit, which turns from green to yellow-green when ripe, is about 2 cm long. 11 Neem comprises of several phytochemicals such as azadirachtin, meliantriol, and salanin. 12 Additionally, azadirachtin is regarded as a prominent biopesticide due to its mode of action and high concentrations, particularly in Neem fruits. 13 Studies have shown that different plant parts exhibit therapeutic, insecticidal, and pest control abilities effectively. 14 Extract of Neem bark treats gastric hypersecretion and gastro-duodenal ulcer. 15 The leaves are used in traditional medicine as antimicrobial, antioxidant hepato-protective, and anti-inflammatory agents.

“…13 Since ancient times, the smoke produced by burning dried leaves of A. indica has been used as a mosquito repellent, 14 and neem oil has been reported to have remarkable potency as spermicides and contraceptives. 2 Recently, to reduce global warming, researchers' attention has been drawn to alternative energy sources such as biofuels, particularly from nonedible foods such as neem, 1 and this has led to neem oil being widely explored as a renewable energy source for biofuels production [15][16][17][18][19][20][21] and as eco-friendly industrial coatings. 22,23 This paper aims to provide an extensive bibliometric analysis of neembased academic publications by presenting the most significant advancements in the field of neem research between 1971 and 2017 using the Web of Science database.…”

Recently, there has been a surge in interest in evaluating research accomplishments based on publications using bibliometric tools. This study aims to investigate the top 100 most cited articles in Neem using bibliometric analysis while also providing readers with a practical guide for determining the most influential publications over the past decades. VOSviewer 1.6.6, the "Bibliometrix app" in R. studio cloud, and SPSS were used to analyze the data. The top 100 highly-cited articles in Neem, which included 91 articles and nine reviews, were published between 1971 and 2017. The articles received a total citation score of 14,186 (citations ranging from 65 to 1,531), with an average total citation score of 141.9 and a total citation score per article of 10.07. 398 authors from 22 countries contributed a total of 100 publications, with Bhattacharyya KG being the most productive and influential. Researchers from India published about 45 percent of the articles and had the highest number of citations (8637). The Banaras Hindu University in India was discovered to be the top-ranked institution, with six publications and 1,491 citations. The top 100 literature was published in 72 journals, with the Journal of Ethnopharmacology publishing nine papers. The findings of this study provided extensive information and research direction for future research in this domain, including the most influential journals, countries, authors, institutions, and articles and mapping co-authorship and reported keywords.
