Purpose This study aims to develop synthetic ester lubricating oil using renewable sinapic acid as raw material, explore the structural design and selection of materials for green, high-performance oils. Design/methodology/approach A series sinapate oils were synthesized through esterification alkoxylation reactions source material. The molecular structures characterized by nuclear magnetic resonance spectroscopy, Fourier transform infrared spectroscopy elemental analysis. evaluated safety, viscosity-temperature properties, thermal oxidative stability, well friction reducing anti-wear characteristics. Findings Compared commercial base tris (2-ethylhexyl) trimellitate (Phe-3Ci8), bio-lubricant exhibits superior antifriction properties. Notably, JCi8-C12 sample performed exceptionally well, coefficient 11.42% wear volume (WV) 54.44% in steel/steel tribo-pairs. In steel/aluminum tribo-pairs, decreased 27.48%, while WV was reduced 85.81%. Mechanistic studies reveal that introduction short-chain methoxy groups stable conjugated systems (aromatic rings double bonds) inhibit oxidation decomposition at elevated temperatures. p-p stacking effect enables lubricant molecules arrange stably on surfaces, forming a durable film. Originality/value utilization biomass resources green with excellent performance not only enhances added value waste from agricultural processing but also offers significant benefits terms both economic environmental sustainability.

Abstract As the manufacturing industry shifts toward environmentally sustainable practices, grinding—a high-precision processing method—is commonly used to ensure final workpiece dimensions and surface quality. The greening of grinding processes has emerged as an important challenge for both academia industry. Numerous studies proposing different methods have increased rapidly; however, technical mechanisms development trends remain unclear. This paper applies bibliometric analyze relevant articles published on WOS from 2008 2023. Results show that China highest number publications (45.38%), with research institutions primarily located in China, India, Brazil. Among publishing journals, 70% are classified Q2 or above. Additionally, popular authors influential this field identified. Keyword frequency hotspot literature analysis reveal focuses minimal quantity lubrication (MQL) grinding, especially using biolubricants nanoparticles improve performance. article reviews effects MQL. It further examines how multi-energy applications enhance MQL by influencing droplet atomization, wettability, machining A low-temperature improves heat exchange capacity droplets, while electrostatic enhances contact angles dispersion. Ultrasonic energy atomization biolubricants, magnetic fields facilitate nanoparticle penetration into zone, reducing forces. innovations wheel structures solid can reduce temperatures presents a comprehensive review eco-friendly hotspots, providing support theoretical guidance
