Identifying the origin of macroscopic friction between clay mineral surfaces

Overview of the press release

NIMS, the University of Tokyo and Hiroshima University jointly discovered for the first time, through theoretical calculations and experiments, that macroscopic frictions occurring between clay mineral surfaces originate from interatomic electrostatic forces between these surfaces. This finding may facilitate the design of solid lubricant materials and understanding of earthquake-causing fault slip mechanisms.



The research was published in Science Advances on December 21, 2018.
