Continuous Isotropic-Nematic transition in compressed rod-like based nanocolloid
Joanna Łoś, Aleksandra Drozd-Rzoska, Sylwester J. Rzoska +2
Landau - de Gennes mean field model predicts the discontinuous transition for the Isotropic - Nematic transition, associated with uniaxial and quadrupolar order parameter in three…
Critical-like behavior of ionic-related, low-frequency dielectric properties in compressed liquid crystalline 8OCB and its nanocolloid
J. Łoś, A. Drozd-Rzoska, S. J. Rzoska
The report presents pressure-related broadband dielectric spectroscopy (BDS) studies in liquid crystalline octyloxycyanbiphenyl and its nanocolloid with BaTiO3 nanoparticles, focus…
Pretransitional effects of the isotropic liquid-plastic crystal transition
A. Drozd-Rzoska, S. Starzonek, S. J. Rzoska +3
We report on strong pretransitional effects across the isotropic liquid-plastic crystal melting temperature in linear and nonlinear dielectric response. Studies were carried out fo…
Unique dynamic crossover in supercooled x,3-dihydroxypropyl acrylate (x = 1, 2) isomers mixture
Szymon Starzonek, Aleksandra Kędzierska-Sar, Aleksandra Drozd-Rzoska +2
The previtreous dynamics in glass forming monomer, glycerol monoacrylate (GMA), using broadband dielectric spectroscopy (BDS) was tested. Measurements revealed the clear dynamic cr…
Dynamics in poly(propylene glycol) and silica oxide nanoparticles composite glassforming system
M. Głuszek, A. Antosik, R. Żurowski +5
Results of broadband dielectric spectroscopy and rheological studies of poly(propylene glycol) + SiO nanocomposites are presented. They show that the dynamics in high-concent…
