Materials scientists are measuring the rolling friction of tiny, micrometer-sized particles. These measurements permit them to better understand everyday products such as concrete.

which suggests that such biphasic dependence is due to the fact that a very soft channel wall will result in small deformation of the nucleus and consequently reduced cell-wall friction, while larger ...
