The analysis led to the:

critical-like & activated scaling terms    for the temperature path  & the     critical-like portrayal    for the pressure path. 

The universality of the proposed above relations is evidenced for glass formers belonging to: 

low molecular weight liquids, polymers (melt and solid), plastic crystals, liquid crystals, resins, relaxors, biosystem (polyalcohols).

In 2019 Aleksandra Drozd-Rzoska showed NEW evidence for the previtreous behavior of the relaxation time and the apparent fragility,

offering a NEW gate for glass transition models. She showed that the temperature and pressure-related relaxation time can show the “universal” pretransitional anomaly, both on approaching the glass transition pressure and the dynamic crossover: 

The progress in understanding and describing the anomalous previtreous increase of the structural relaxation time

or viscosity is considered as the key to resolving the grand cognitive challenge of the glass transition.

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.
