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

There's rarely time to write about every cool science-y story that comes our way. So this year, we're once again running a special Twelve Days of Christmas series of posts, highlighting one science ...

Powder tribology offers a way to understand particle interactions at their contact points, capturing both interparticle friction and surface adhesion. These interactions have been studied in ...

Cohesion is often seen as a key factor to bulk powder flowability and is frequently blamed for problems in powder processing. Particles attract to one another in cohesive powder to create agglomerates ...

The measuring tip of an atomic force microscope with a specially designed holder in which a spherical particle is “trapped”. Lacquers, paint, concrete—and even ketchup or orange juice: Suspensions are ...
