Researchers have detailed the physics behind a phenomenon that allows them to create spin in liquid droplets using ultrasound waves, which concentrates solid particles suspended in the liquid. The ...

Imagine a liquid that flows freely one moment, then stiffens into a near-solid the next, and then can switch back with a simple change in temperature. Researchers at the University of Chicago Pritzker ...

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 ...

Tiny particles such as ice crystals or ash particles tend to oscillate as they settle through the atmosphere. In their experiments, the scientists were able to track non-spherical particles of size ...

Powder is a collection of single solid particles, which in most cases may be considered a basic unit. Powder is typically comprised of solid particles, interparticle voids, as well as open and closed ...

In A Nutshell Scientists discovered a previously unknown form of mixing that occurs when large groups of dense particles settle through fluid, contradicting predictions from a long-accepted theory. A ...

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 ...
