The shear viscosity minimum of freely flowing nematic liquid crystals
Jan Jadżyn,Grzegorz Czechowski +1 more
TL;DR: In this paper, the analysis of temperature dependence of the shear viscosity of freely flowing nematic liquid crystals was performed and it was shown that the anisotropic fluid adopts such a manner of flow, which corresponds to the minimum of its viscosities at given conditions.
Journal ArticleDOI
The anchoring of nematic molecules on magnetic particles in some types of ferronematics
Peter Kopčanský,I. Potočová,Martina Koneracka,Milan Timko,A. G. M. Jansen,Jan Jadżyn,Grzegorz Czechowski +6 more
TL;DR: In this paper, the structural transitions in ferronematic based on 8CB and 6CHBT, exposed to combined electric and magnetic fields, were investigated and the influence of the presence of magnetic admixture on the Fredericksz transition threshold was studied.
Journal ArticleDOI
Viscosity of the Homologous Series of n-Alkylcyanobiphenyls
TL;DR: In this article, the shear viscosity data for the isotropic phase of the homologous series of mesogenic n-alkylcyanobiphenyls (CnH2n+1PhPhC⋮N, nCB) were presented.
Journal ArticleDOI
Prenematic behavior of the electric-field-induced increment of the basic thermodynamic quantities of isotropic mesogenic liquids of different polarity.
Jan Jadżyn,Grzegorz Czechowski +1 more
TL;DR: Temperature dependences of the static dielectric permittivity and its derivative, obtained for isotropic mesogenic liquids composed of the molecules of different polarity in relation to the basic thermodynamic quantities, are analyzed.
Journal ArticleDOI
Static and dynamic dielectric behavior of mesogenic compounds of different polarity in the vicinity of the isotropic to nematic phase transition.
TL;DR: Mesogenic compounds belonging to the two well-known -cyanophenyl, and -isothiocyanatophenyl homologous series, show an essential difference in the pretransitional dielectric behavior in the vicinity of the isotropic to nematic (I-N) phase transition.
