The Size Effect of Boron Nitride Particles on the Tribological Performance of Biolubricants for Energy Conservation and Sustainability (2013, background): “Despite the environmental advantages to using pure natural oils, they do suffer from poor thermal and oxidative stability, biological (bacterial) deterioration, hydrolytic instability, poor fluid flow behavior, solidification at low temperatures, and on occasion, high wear rates [7, 17–22].”
