The information comes from a collaborative research effort, suggesting a focus on scientific advancement rather than political agendas.

Through joint research with the U.S. Geological Survey and the University of Tokyo, NIMS for the first time experimentally demonstrated friction completely independent of sliding velocity—an ideal that had never been realized—by heating mica, a layered oxide also used as a lubricant material, to 200°C (392°F). NIMS also clarified that this is caused by the disappearance of defects within crystals at high temperatures.
