8OCB and its nanocolloids”, 

Soft Matter, 2022, vol. 18, p. 4502-4512.

Research of our team concentrates on the following aspects:

  • Previtreous dynamics in glass-forming systems

  • Phase transition and critical behavior in critical mixtures of limited miscibility

  • Solid-liquid discontinuous melting transition

  • Impact of fluctuations on dynamics of nanocolloids based on liquid crystals

  • Relaxor ceramics and related polymer-based composites

  • Biosystems related issues

  • High pressure preservation and processing of food, pharmaceuticals, cosmetics

  • Supecritical extraction

Since January 2023  our team has realized the NSC Project, guided by Prof. Sylwester J. Rzoska.

In this Project, we work on pressure-formed components related to 

glassy matrix and nanocrystallites for INNOVATIVE BATTERIES & FUELL CELLS

Actual  Research Topics

Impact of high pressures & high temperatures on materials amorphous materials for energy storage and conversion

Phase equilibria in mixtures of limited miscibility using

a new generation method for determining phase coexistence curves

Innovative, nonthermal preservation method, High Pressure Precessing of Biosystems

Complex dynamics in different soft matter systems, especially in supercooled liquids,


Pretransitional effects and dynamics in liquid crystals and liquid crystal-based nanocolloids

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.
