    Comparative pecularities of non-uniform textures of lyotropic mesophases of binary and ternary systems based on N-cetyl-N,N,N-trimethyl ammonium bromide
    (Elsevier Science Bv, 2003) Nesrullajev, A; Okcan, M; Kazanci, N
    The mesomorphic properties of the n-cetyl-n,n,n-trimethyl-ammonium bromide (CTABr) + water and CTABr + decanol + water lyotropic systems and the morphologic properties of the lyotropic mesophases taking place in these systems have been investigated. The existence of hexagonal and nematic-calamitic mesophases in the CTABr + water system and the existence of hexagonal, lamellar, nematic-calamitic and nematic-discotic mesophases in the CTABr + decanol + water system have been revealed. The characters and peculiarities of specific textures, which were spontaneously formed, and non-specific textures, which were induced by deformations, have been investigated. The disclinations of strength and optical signs of singularities taking place in specific and non-specific textures of these lyotropic mesophases have been determined. (C) 2003 Elsevier B.V.
