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 theory of non-ideal gases at thermodynamic equilibrium, for instance the van der Waals gas model, has played a central role in our understanding of coexisting phases, as well as the transitions ...

Atmospheric aerosols, consisting of suspended small solid and liquid particles, influence both climate and air quality. Sub-micrometre-sized particles efficiently scatter visible radiation and can act ...

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 ...
