Self-organization during friction in complex surface engineered tribosystems is investigated. The probability of self-organization in these complex tribosystems is studied on the basis of the theoretical concepts of irreversible thermodynamics. It is

The dynamic photorefractivity in a cell with photoconducting orienting layers, filled with a nematic liquid crystal (LC) 6CHBT and a mixture of anthraquinone dyes AD1 and AD2, has been investigated. The single-pulse mode, in which the polarity and am

A new mechanism of photorefractivity in nematic liquid crystal cells with photoconductive orienting layers, referred to as dynamic photorefractivity, is proposed. The essence of this mechanism is as follows: an external ac electric field excites quas

We report observation of the dynamic enhancement of photorefractive effect in dye-doped nematic liquid crystal in the presence of an applied ac electric field. The multi-wave mixing efficiency in a planar cell with photoconductive orienting layers ha

The director reorientation in the liquid crystals (LCs) cells initiated by the trans‐cis isomerization of azo-dyes was studied with the aid of pump‐probe‐beam experiments. Two diAerent types of the samples were used, namely, a planar aligned LC

The photoelectric phenomena and orientational nonlinearity induced by nanosecond laser pulses in planar layers of liquid crystals oriented by silicon oxide (SiO) and activated with polymethine dyes were investigated. These phenomena are due to the ph

The effect of flow-reorientation coupling on to the relaxation process of refractive index grating in nematic liquid crystals has been theoretically investigated. It is shown that in case of oblique incidence of the two beams onto the homeotropic cel

Orientation effect induced in bleachable dye doped planar nematic layer has been observed. It is believed that the effect is caused by dye-induced torque and hydrodynamic reorientation of the layer.
