Solids, liquids and gases. In a solid like this brick, the particles are regularly arranged touching their neighbours and move only by vibrating. This explains why solids have a fixed shape.

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

In this model, solids have particles fixed tightly together in rows so they can’t move. In liquids, the particles are touching but are free to move around each other like balls in a ball pool.

Would you call it a solid, liquid, or a gas ... When the mixture is stirred or hit, the particles push together and make the liquid harder to move through. When the mixture is stirred slowly or hit ...

A supersolid is a paradox of physics — a material that is both solid and liquid at the same time ... harnessing light-matter ...

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

For the first time, ETH materials scientists are measuring the rolling friction of tiny, micrometre-sized particles. These ...
