We investigate a stochastic model describing a column of grains in the jamming limit, in the presence of a low vibrational intensity. The key control parameter of the model, <InlineEquation ID="Equ1"> <EquationSource Format="TEX">$\epsilon$</EquationSource> </InlineEquation>, is a representation of granular shape, related to the reduced void space. Regularity and irregularity in...</equationsource></inlineequation>

We demonstrate with the aid of visual investigations that multiply reentrant liquid–liquid transitions can be obtained in ethyl alcohol (E)–water (W) mixtures, by the addition of ions. Multiplicity of reentrance can be tuned by changing the concentration, size, or the structure forming...
