2009.03.25 Students at liquid crystals laboratory

3rd year students of physics department are involved in liquid crystals laboratory studies. In laboratory practice are included works for studying: nematics electroconductivity, effects of dynamic light scattering, electro-convective flows, birefringence dispersion, optical rotation and memory effects in compounds of nematics with cholesterics etc...
