Influence of dielectric layers on estimates of diffusion coefficients and concentrations of ions from impedance spectroscopy

Maxim V. Khazimullin, Yuriy A. Lebedev

We present the analysis of the impedance spectra for a binary electrolyte confined between blocking electrodes with dielectric layers. An expression for the impedance is derived fr…

Spatiotemporal complexity of electroconvection patterns in nematic liquid crystals

Alexei Krekhov, Bernd Dressel, Werner Pesch +2

We investigate a number of complex patterns driven by the electro-convection instability in a planarly aligned layer of a nematic liquid crystal. They are traced back to various se…

Dynamics of cholesteric structures in an electric field

O. S. Tarasov, A. P. Krekhov, L. Kramer

Motivated by Lehmann-like rotation phenomena in cholesteric drops we study the transverse drift of two types of cholesteric fingers, which form rotating spirals in thin layers of c…

Flexoelectric Instability in Nematic Liquid Crystal between Coaxial Cylinders

I. V. Kotov, M. V. Khazimullin, A. P. Krekhov

The stability of the equilibrium configurations of a nematic liquid crystal confined between two coaxial cylinders is analysed when a radial electric field is applied and the flexo…

Dynamics of Nematic Liquid Crystal under Oscillatory Flow: Influence of Surface Viscosity

I. Sh. Nasibullayev, A. P. Krekhov, M. V. Khazimullin

We analyse the influence of a surface viscosity on the orientational dynamics of a nematic liquid crystal subjected to an oscillatory Couette flow. Approximate analytical solutions…

Temperature Dependence of Anchoring Energy of MBBA on SiO-Evaporated Substrate

M. V. Khazimullin, A. P. Krekhov, Yu. A. Lebedev

The temperature behaviour of the anchoring energy of nematic liquid crystal MBBA at the substrates with oblique SiO evaporation and director orientation at the interface have been…

Influence of weak anchoring on flow instabilities in nematic liquid crystals

O. S. Tarasov, A. P. Krekhov, L. Kramer

We analyse the homogeneous instabilities in a nematic liquid crystal subjected to plane steady Couette or Poiseuille flow in the case when the director is pre-aligned perpendicular…

Orientational transition in nematic liquid crystals under oscillatory Poiseuille flow

P. Toth, A. P. Krekhov, L. Kramer +1

We investigate the orientational behaviour of a homeotropically aligned nematic liquid crystal subjected to an oscillatory plane Poiseuille flow produced by an alternating pressure…

Director precession and nonlinear waves in nematic liquid crystals under elliptic shear

T. Borzsonyi, A. Buka, A. P. Krekhov +2

Elliptic shear applied to a homeotropically oriented nematic above the electric bend Freedericks transition (FT) generates slow precession of the director. The character of the acc…
