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

This friction is many times more than rolling friction, which explains the enormous thickness ... models to simulate suspensions with a large fraction of particles, for example, and thus find the best ...

When many people see horsepower numbers, they immediately assume that high horsepower results in a high top speed. However, ...
