Anchoring transitions in nematic-discotic lyotropic mesophase under magnetic field
(Natl Inst Optoelectronics, 2015)Magneto-morphologic and orientational properties of the lyotropic nematic-discotic N-D mesophase have been studied by the polarizing optical microscopy technique. Texture transformations from the schlieren texture to the ... -
Elaboration of the structural and physical characteristics: Ni-doped ZnO bulk samples prepared by solid state reactions
(Natl Inst Optoelectronics, 2011)Ni-doped ZnO (Zn1-xNixO, with 0.25 <= x <= 0.50) diluted magnetic semiconductors were prepared by the solid state reaction method. We have studied the structural properties of the samples by using the X-Ray Diffraction ... -
Lyotropic nematic mesophases: peculiarities of singularities and inversion walls in specific and non-specific extures
(Natl Inst Optoelectronics, 2013)Peculiarities of various defects and disclinations in specific and non-specific textures of the optically uniaxial and biaxial lyotropic nematic mesophases were investigated. Sodium dodecylsulphate (SDS) [sodium lauryl ... -
