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

ETH Zurich scientists measure rolling friction in micrometer-sized particles, enhancing understanding of suspensions in ...

Suspensions are widespread in industry and everyday life. By a suspension, materials scientists mean a liquid in which tiny, ...

From ketchup and paint to concrete and orange juice, many everyday materials are what scientists call suspensions—liquids ...

But some occasions call for something a bit more breezy. Flip flops, pool slides, thongs, sandals—call them what you want—today the world's leading brands are placing more and more emphasis on ...

The slide is a problem for the health insurance giant, no doubt. But the decline also created a broader stir in markets, specifically for the Dow Jones Industrial Average (^DJI). Unlike its peer ...

The researchers' analysis revealed that the lion's share of the microplastics were released from the gum in the first two minutes of chewing—thanks to the mechanical action, rather than the enzymatic ...
