Suppression of spatially periodic patterns by dc voltage.

Physical review. E

Éber N, Salamon P, Fekete BA, Karapinar R, Krekhov A, Buka Á.
PMID: 27176360
Phys Rev E. 2016 Apr;93:042701. doi: 10.1103/PhysRevE.93.042701. Epub 2016 Apr 07.

The effect of superposed dc and ac applied voltages on two types of spatially periodic instabilities in nematic liquid crystals, flexoelectric domains (FD), and electroconvection (EC) was studied. The onset characteristics, threshold voltages, and critical wave vectors were determined....

Measuring the deformation of a ferrogel sphere in a homogeneous magnetic field.

The Journal of chemical physics

Gollwitzer C, Turanov A, Krekhova M, Lattermann G, Rehberg I, Richter R.
PMID: 18447481
J Chem Phys. 2008 Apr 28;128(16):164709. doi: 10.1063/1.2905212.

A sphere of a ferrogel is exposed to a homogeneous magnetic field. In accordance to theoretical predictions, it gets elongated along the field lines. The time dependence of the elastic shear modulus causes the elongation to increase with time,...

Flexoelectricity and competition of time scales in electroconvection.

Physical review. E, Statistical, nonlinear, and soft matter physics

Tóth-Katona T, Eber N, Buka A, Krekhov A.
PMID: 18851142

Visualizations rely on highlighting to attract and guide our attention. To make an object of interest stand out independently from a number of distractors, the underlying visual cue, e.g., color, has to be preattentive. In our prior work, we...
