Role of wettability, adhesion, and instabilities in transitions during lubricated sliding friction

Proceedings of the National Academy of Sciences, Volume 122, Issue 32, August 2025. <br/>SignificanceFriction of lubricated sliding of soft solids usually falls in one of three regimes; sliding occurs with a) full solid–solid contact (boundary lubrication, BL), b) mixed solid–solid and solid–liquid–solid contact (mixed lubrication, ML), and c)…
