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 ...

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. In a ...

Scientists have observed transitions into and out of an exotic state of matter found between liquid and solid in 2-D materials (Sci. Rep. 2021, DOI: 10.1038/s41598-020-80082-x). The hexatic phase ...

The state of matter is a deceptively simple concept. It turns out that any material, no matter what it is made of, can exist in one of three forms: solid, liquid or gas. These are categories of stuff ...

We explore Supercritical Fluids and how being "in the between" is their superpower. Supercritical Fluids are one the strangest states of matter and yet they are found everywhere from Decaf Coffee, to ...

Centrifugal pumps are critical components in many industrial applications requiring the transport of slurries – mixtures of solids suspended in a liquid. Their performance is strongly impacted by the ...

Scientists have discovered a new state of matter that isn't a solid, liquid, or gas. Researchers call this new type of material a 'corralled supercooled liquid'. Atoms in a liquid are normally like ...
