Artificial Intelligence–Based Characterisation of Eco‐Friendly <scp>TiO₂</scp>‐Based Nanofluid Blended With <i>Moringa oleifera</i> Oil

ABSTRACT Characterisation of eco‐friendly biodegradable lubricant is a significant investigation in the replacement of the toxic mineral/synthetic oil that creates a negative impact on health. In this study, the nanoparticle titanium dioxide (TiO 2 ) was synthesised by the coprecipitate method and dispersed in the palm oil blended with Moringa oleifera seed oil (enriched palm oil‐EPO) to prepare a biodegradable lubricant. Structural and compositional analysis of TiO 2 nanoparticles was carried out using scanning electron microscope (SEM), X‐ray diffraction (XRD) and Fourier transform infrared spectroscopy analysis (FTIR). The biodegradable lubricant nature of TiO 2 dispersed at different volume fractions in EPO was investigated by varying viscosity and density with temperature (30°C–60°C), and the Brownian motion of the particle in the oil was studied through the diffusion constant, diffusion time and Brownian velocity. The biodegradable lubricant nature of TiO 2 has been analysed using machine learning (ML) techniques that categorise the lubricant nature of the blended oil.
