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 ...

Almost everything is made of particles. Particles can be atoms, molecules or ions. Particles behave differently in solids, liquids and gases. The particle model explains the differences between solids ...

Tiny solid particles — like pollutants, cloud droplets and medicine powders — form highly concentrated clusters in turbulent environments like smokestacks, clouds and pharmaceutical mixers. What ...

Introduction Have you ever heard the expression, "solid as a rock"? As it turns out, rocks are not entirely solid. Rocks actually have tiny pockets of air inside them. This is obvious when you look at ...

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 ...
