This study proposes the formulation of a palm olein-based biolubricant enriched with hybrid nanoparticles (e.g., TiO₂ + SiO₂ or TiO₂ + MoS₂). The approach involves nanoparticle surface modification and advanced dispersion techniques to enhance oxidative stability, viscosity index, load-carrying capacity, and to reduce friction and wear in small motorcycle engines. The primary objectives are: (1) to improve tribological performance (coefficient of friction and wear) under typical motorcycle operating conditions; (2) to enhance the oxidative stability and service temperature range of palm olein through chemical treatments such as esterification, epoxidation, or polyol esterification combined with nanoparticle incorporation; and (3) to develop an additive package and dispersion protocol that are compatible with engine seal and material systems. The expected outcome is a sustainable and high-performance hybrid nano-biolubricant suitable for motorcycle applications, combining environmenta
The knee joint is a complex articulation comprising the femur, tibia, fibula, patella, cartilage, meniscus, and synovial membrane, which rely on synovial fluid for effective lubrication and wear protection. Degenerative conditions such as osteoarthritis lead to the depletion or degradation of this natural lubricant, resulting in increased friction, wear, and joint discomfort. This study aims to develop a bioinspired nano-biolubricant designed to replicate and enhance the natural lubricating functions of synovial fluid. The proposed formulation utilizes biocompatible and biodegradable base materials such as seaweed- or palm-derived esters combined with functionalized nanoparticles (e.g., TiO₂, and or SiO₂) to achieve superior boundary & hydrodynamic lubrication. Surface modification and dispersion engineering are employed to ensure nanoparticle stability and compatibility with biological environments. Comprehensive evaluations—including tribological performance & Simulated Body Fluids.
