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.

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

Dissolving a solid in a liquid depends on the interactions and attractions between the molecules of the liquid (solvent) and the particles of the solid (solute). Dissolving happens when the attraction ...

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

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

solid-liquid transitions in systems of small molecules, thermodynamic integration methods and their applications to equilibrium solids and grain boundary kinetics, phase transitions in systems of ...
