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, ...

When a tiny droplet of cold fluid mixes with a high-temperature solid particle, a vapor layer forms between them, and they never actually touch. Ohio State University researchers have performed the ...

Several years ago, scientists discovered that a single microscopic particle could rock back and forth on its own under a ...

A video demonstrating ferrofluids and its potential applications. Ferrofluids are composed of nanoscale ferromagnetic, or ferrimagnetic, particles suspended in a carrier fluid, usually an organic ...

ETH Zurich Materials Scientists are the first to measure the microscopic forces involved when particles in suspensions such as concrete or paint roll past each other. Previously, such measurements ...

Lacquers, paint, concrete—and even ketchup or orange juice: Suspensions are widespread in industry and everyday life. By a suspension, materials scientists mean a liquid in which tiny, insoluble solid ...
