Optimization of the core composition of the pressurized water reactors is associated with the calculation of the temperature fields of heat exchange microcells containing separate fuel elements. Taking into account the radiation-conductive heat trans

Within the macroscopic Landau-de Gennes approach, we examine the Gaussian normal mode fluctuations of semi-infinite nematic liquid crystals in a regime of critical wetting. It is argued that surface free-energy potentials that strongly suppress the l

We have synthesized and characterized by IR, UY,1H, and13C NMR spectroscopy new spiropyrans based on 2-thioxo-3 phenyl-5,5-dimethyl-1,3-oxazolidine. We have studied their photochromic properties in 2 propanol at -80°C. In the electronic spectra of p

We report on onset of a surface induced phase in droplets of OOBA liquid crystals desplaying optical properties typical for the smectic-A state. The latter state does not exist in the bulk phase diagram of the system. The surface phase appears in a t

Our microtextural as well as depolarized light scattering analyses of 4-n-octyloxybenzoic acid liquid crystal droplets provide evidence for a possible smectic A ordering induced by the free surface. This appears near the bulk smectic C-nematic transi
