The long-range supercritical changes of dielectric constant, resembling ones observed in the isotropic phase of rod-like liquid crystalline compounds, are evidenced on approaching liquid-solid discontinuous phase transition. The 'supercriticality' ca

The model discussion focused on links between the unique properties of relaxor ceramics and the basics of critical phenomena physics and glass transition physics. It indicates the significance of uniaxiality for appearing mean-field features near par

Landau - de Gennes mean field model predicts the discontinuous transition for the Isotropic - Nematic transition, associated with uniaxial and quadrupolar order parameter in three dimensions. This report shows pressure-related dielectric studies for

The report shows the temperature behavior of the real part of dielectric permittivity in the static (dielectric constant) and lo-frequency (LF) domains in bulk samples of 11CB and BaTiO3-based nanocolloids. The study covers the Isotropic Liquid (I),

Melting/freezing are canonical examples of discontinuous phase transitions, for which no pretransitional effects in the liquid phase are expected.For the solid phase, weak premelting effects are evidenced. This report shows long-range, critical-like,

Coexistence curves in mixtures of limited miscibility with the lower critical consolute temperature (LCT), of 3-picoline with deuterium oxide (D$_2$O), and D2O/H2O have been determined. They were tested with respect to the order parameter, the diamet

The lack of ultimate scaling relations for previtreous changes of the primary relaxation time or viscosity in glass-forming systems constitutes the grand fundamental challenge, also hindering the development of relevant material engineering applicati

This paper presents results for systems formed in a solid glassy state after nanocrystallization process above the glass temperature. We analyze electric conductivity and relaxation processes after such treatment under high temperature (HT) and high

In this report we present the first ever results of strong pretransitional effect observed for the maximum of absorption peak $${\epsilon}_{max}^{''}(T)$$ in supercooled liquid-crystalline systems near the glass transition temperature. This anomaly m
