Blocking of phase transitions in liquid crystal 5*CB   (isopentylcyanobiphenyl) as a result of surface interactions at the   nano-membranes
  In this paper we present results of dielectric measurements of the liquid crystal (LC) 5*CB arranged in the porous matrices with a pore diameter of 100 and 20nm. We analyze the effect of surface interactions on the dynamics of molecules. The results were compared with the results of the bulk 5*CB. The most important result is the blocking of phase transition of 5*CB into the solid phase in a matrix of 20 nm.
