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 ...

The reversible switching of macrocyclic molecules between a liquid and a solid phase upon exposure to vapor has been reported. The transition between a solid and a liquid phase, a key process in daily ...

Materials may exist in the Solid, Liquid, and Gas phase. The (p,v,T) conditions determine which phase or phases are in thermodynamic equilibrium. For certain ranges of (p.v,T) more than one phase can ...

Researchers report that the way a tissue's cells are arranged can serve as a fingerprint for the tissue's 'phase' -- whether it is more like a solid, liquid, or gas. For example, tumors that are more ...

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 ...
