“…This issue determined the need to find sources of clean, low-cost energy, and led to the intensification of efforts based on research and revision of production paths, using new and optimized techniques, to promote clean energy production [26,27]. This will support the maintenance of energy security, limit environmental pollution, and reduce the degree of climate change [28,29]. Therefore, the current global evolution must be directed toward low-carbon sources, and most of the future energy must be provided from clean and renewable sources.…”

“…As mentioned, fatty acids are saturated (SFAs), such as palmitic, stearic, and hydroxystearic acids, and unsaturated (UFAs), such as oleic, linoleic, palmitoleic, ricinoleic, and linolenic acids, etc. [24,28]. Although SFAs have a negligible effect compared to UFAs on the biodiesel oxidation process, the availability and cost contribute to the choice of the type of raw material used in each area for biodiesel production.…”

A major problem that limits the use of biodiesel is maintaining the fuel at the specified standards for a longer period. Biodiesel oxidizes much more easily than diesel, and the final oxidation products change its physical and chemical properties and cause the formation of insoluble gums that can block fuel filters and the supply pipes. This instability of biodiesel is a major problem and has not yet been satisfactorily resolved. Recently, the use of biodiesel has increased quite a lot, but the problem related to oxidation could become a significant impediment. A promising and cost-effective approach to improving biodiesel’s stability is to add appropriate antioxidants. Antioxidants work better or less effectively in different biodiesel fuels, and there is no one-size-fits-all inhibitor for every type of biodiesel fuel. To establish a suitable antioxidant for a certain type of biodiesel, it is necessary to know the chemistry of the antioxidants and factors that influence their effectiveness against biodiesel oxidation. Most studies on the use of antioxidants to improve the oxidative stability of biodiesel have been conducted independently. This study presents an analysis of these studies and mentions factors that must be taken into account for the choice of antioxidants so that the storage stability of biodiesel fuels can be improved.

“…In mechanical mechanisms, lubrication is one of the most successful ways to reduce energy consumption and increase machine productivity. The improvement of machine performance is due to friction and wear reduction, although the nature of the added additives always depends on the effectiveness of the lubricant [1][2][3][4] . The application of nanoparticles as additives in lubricating medium is gaining popularity as nanotechnology advances.…”

In this research, the tribological behavior of two distinct carbon nanotubes and the mechanisms influencing tribological performance were investigated. High frequency reciprocating rigs (HFRR) were used for the study, along with rapeseed oil as the base lubricant and commercial SAE 5W 30 as the benchmark. The experiment used particle concentrations of 0.5, 1, and 1.5 wt.% for MWCNTs and EC-CNTs, respectively, as lubricant additives. According to tests on the' viscometric properties, blends of both additives at a concentration of 1 wt.% produced the best results in terms of viscosity index. When compared to base lubricant, 1 wt.% MWCNTs performed better in frictional analysis at 80 N than 1 wt.% EC-CNTs, but less well than SAE 5W 30 benchmarks. In comparison to other evaluated samples, 1 wt.% EC-CNT exhibited remarkable results at higher loads of 100 N. Based on the investigation, EC-CNTs showed accumulation of particles at the front and back of the sliding ball under less operating conditions. This restricts the diffusion of the particles to the contact region, but it disappears at higher conditions. At a load of 100N, MWCNT and EC-CNT reduced friction and wear by 29.3%, 40.9%, and 30.8%, 45.5%, while SAE 5W 30 produced 45% and 36.4%, respectively. The ability of the additives to convert the direct sliding contact into a rolling mechanism and the formation of tribo-film were attributed to their successful performance. The outcomes clearly demonstrate that EC-CNTs behaved similarly to MWCNTs and SAE 5W 30 lubricants, making it appropriate for lubrication application.

“…Fuel properties of plant's oil and its derivatives are subjective to the plant's variety, cropping system, maturity stage, storage conditions and post-harvest treatments. Biodiesel acidic content, physiochemical parameters, and fatty acid profile are dependent on their corresponding values in the parent plant or animal oil (Nuhanovic et al, 2018;Eboibi et al, 2021;Awad et al, 2022).…”

The engine performance of biodiesel had become a major concern. Improving the acid and oxidation stability of groundnut oil biodiesel (GOME), with various plant waste extracts, was carried out on in this study. Freshly prepared GOME was blended with onion extract (OE) and ginger extract (JE), at the rate of 100:1 parts per million, and stored at a temperature of 30±50C for 28 days. At the end of the experimental period, the acid content and oxidation value of the biodiesel treated with both natural additives, were lower when compared to the biodiesel with additives. It was observed that untreated GOME acid value increased from 1.37 - 2.23 mgKOH/g, the acid value of the GOME containing OE increased from 1.35 – 1.81 mgKOH/g, and the acid content of the GOME treated with JE increased from 1.34 – 1.94 mgKOH/g. Regarding the oxidation stability, it was observed that the un-amended GOME oxidative stability decreased from 3.14 h to 2.44 h, the GOME amended with OE additive declined from 5.37 to 4.57 h, while the GOME treated with JE additive decreased from 4.99 h to 4.21 h. The findings of this study had revealed that incorporating natural additives into GOME, yield biodiesel with better oxidation stability. It was also noted that the blended GOME met the ASTM approved recommendation for biodiesel; unlike the results recorded for the GOME that was untreated with the natural additives.
