High-pressure and temperature dependence of dielectric relaxation in supercooled di-isobutyl phthalate
TL;DR: Results are presented for isothermal, high-pressure, and temperature ~under atmospheric pressure! measurements of complex dielectric permittivity in supercooled di-isobutyl phthalate, and the relaxation times determined from the temperature study obey the temperature Vogel-Fulcher-Tammann ~VFT! law.
Journal ArticleDOI
Test of the Einstein-Debye Relation in Supercooled Dibutylphthalate at Pressures up to 1.4 GPa
TL;DR: Broadband dielectric measurements were carried out on di-n-butyl phthalate under isothermal conditions at hydrostatic pressures up to 1.6 GPa and revealed that no breakdown of the Einstein-Debye relation is induced by high compression.
Journal ArticleDOI
Fragility and basic process energies in vitrifying systems.
Julio Cesar Martinez-Garcia,Sylwester J. Rzoska,Aleksandra Drozd-Rzoska,Szymon Starzonek,John C. Mauro +4 more
TL;DR: This report shows that fragility is determined by the ratio between two fundamental process energies, viz. the activation enthalpy and activation energy.
Journal ArticleDOI
Thermodynamic scaling and the characteristic relaxation time at the phase transition of liquid crystals.
C. M. Roland,R. B. Bogoslovov,Riccardo Casalini,A. R. Ellis,Scott Bair,Sylwester J. Rzoska,Krzysztof Czupryński,Stanisław Urban +7 more
TL;DR: There is a surprising relationship between the thermodynamic conditions defining the stability limits of a liquid crystalline phase and the dynamic properties reflected in the magnitude of the longitudinal relaxation time.
Journal ArticleDOI
On the pressure evolution of dynamic properties of supercooled liquids
TL;DR: In this article, a pressure counterpart of the Vogel-Fulcher-Tammann (VFT) equation for representing the evolution of dielectric relaxation times or related dynamic properties is discussed.
