The analysis led to the:

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

This research focuses on the experimental search for universal patterns in Soft Matter systems and modeling that can solve important cognitive puzzles.

Recalls the basics of the Physics of Critical Phenomena and the Physics of Glass transition.



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

low molecular weight liquids, polymers, 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 the “universal” pretransitional anomaly,

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.
