An Investigation into the Quality of Distillate Diesel Fuel at Selected Service Stations in Freetown’s Western Area
Abstract: As a critical energy source for global transport and industry, diesel fuel quality is of paramount importance. This study evaluates and compares the quality of diesel fuel samples by analyzing key parameters: sulfur content, density, cetane index, and kinematic viscosity. The properties of diesel fuel samples from six (6) Fuel Stations of various Oil Marketing Companies (OMCs) are compared with National Technical specifications limits of the Sierra Leone Standards Bureau, …

Physicochemical Analysis of Oil Extracted from Raphia Sudanica Fruit Sold in Edu Local Government Area of Kwara State, North Central Nigeria
Abstract: Raphia sudanica, commonly called Raphia hookeri or bamboo palm fruit, is one of the most valuable species among known palm fruits found in Nigeria and is widespread in major parts of West Africa. In this study, oils extracted and analyzed from Raphia sudanica fruits (pulp and seed) revealed the respective physicochemical values; acid value (5.56, 6.10 mgKOH/g), peroxide value (2.44, 5.82 Meq/kg), iodine value (41.30, 68.10 gI₂/100 g), saponification value …

Tribological Assessment of Chemically Modified Jatropha Curcas Oil Developed by Addition of Graphite Nanoparticles for Biolubricant Applications
Abstract: As an alternative to petroleum-based lubricants, environmentally friendly bio-based lubricants are gaining popularity in the lubrication industry. A sustainable bio-based lubricant, Jatropha Curcas Oil (JCO) incorporates nanoparticles as additives. Nevertheless, this oil cannot be used directly as a biolubricant due to its low oxidative stability. By redesigning the oil's molecular structure through chemical modification, this restriction can be overcome. Epoxidation and oxirane ringopening were the two steps used in this …
