The linearized, derivative-based plot on the distortions shows the sensitive validity of critical–like portrayal. Straight lines show domains of the validity of such a description. Their intersection can serve as a possible indication of the dynamical crossover temperature. Structures of tested glycerol, threitol, and sorbitol are also given. They belong to polyols' homologous series. The previtreous behavior of the primary relaxation time and the apparent fragility are also tested for a broad range of pressures. 

The results can also be applied to describe previtreous changes in viscosity, diffusion, or electric conductivity. Note that fragility is directly coupled to the steepness index, apparent activation enthalpy (temperature path), or apparent activation volume (pressure path).

This WEBSITE was created to realize the following, main  GOALS:

Soft Matter systems have common features, such as the dominance of elements or local structures on the mesoscale, combined with their relatively weak interactions, which turns out to be sufficient to obtain a tendency to self-organize with even a small change in parameters. This additionally leads to extraordinary sensitivity to even minor endogenous and exogenous factors, e.g., nanoparticles and pressure. In the case of the latter, relatively low pressures P~1 GPa, or even much lower ones, can lead to phases/states with exotic features, often persisting after decompression.

Worth stressing, that for "classical hard matter" systems, a pressure similar to that at the Earth's core (~300 GPa) is typically required, and the resulting "exotic" properties most often disappear upon decompression.
