Peculiarities of Defective Formations in Heterophase Regions of the Thermotropic Phase Transitions in Liquid Crystals
(Wiley-V C H Verlag Gmbh, 2019)
A unique feature of phase transitions in liquid crystalline materials is the availability of heterophase regions. In such regions, the simultaneous coexistence of high temperature and low temperature phases takes place. ...
Thermotropic cholesteric liquid crystals. Thermo-morphologic, optical refracting and birefringent properties: Direct and reverse phase transitions
(Elsevier, 2020)
Temperature dependences of the average refractive index < n >, refractive indices of the ordinary ray n(o) and the extraordinary ray n(e), and the birefringence Delta n have been investigated in two cholesteric liquid ...
Peculiarities of inversion walls and singular points in oriented textures of nematic mesophase
(Wiley-V C H Verlag Gmbh, 2009)
In this work the nature and peculiarities of the inversion walls and singular points, which can spontaneously arise or can be stimulated in the homeotropic and planar oriented textures of the thermotropic nematogens, have ...
1,3-Dimethyl-5-(3,4,5-tris(alkoxy)benzoyl) barbituric acid derivatives and their liquid crystalline difluoroboron complexes: Synthesis, characterization and comparative investigations of mesomorphic, thermotropic and thermo-morphologic properties
(Elsevier, 2014)
A series of 1,3-dimethyl-5-(3,4,5-tris(alkoxy)benzoyl) barbituric acid derivatives 1a-4a with various chain length were synthesized by our group for the first time through the addition of 1,3-dimethyl barbituric acid to ...
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 ...
Comparative investigations of the thermotropic and optical refractive properties in micellar isotropic phase and nematic-calamitic mesophase of hexadecyltrimethyl ammonium bromide/water and hexadecyltrimethyl ammonium bromide/water/1-decanol lyotropic liquid crystalline systems
(Springer, 2015)
We report the thermotropic properties and measurements of the temperature and concentration dependences of the refractive index in isotropic micellar L (1) phase and nematic-calamitic N (C) mesophase of the hexadecyltrimethyl ...
Study of mesomorphism, thermotropic properties and pitch in new chiral smectogenic imine compounds

Texture transformations and thermo-optical properties of nematic mesogen at nematic-isotropic liquid phase transition
(Elsevier, 2014)
Study of the thermo-morfologic, thermotropic and thermo-optical properties of monomorphic nematic mesogen has been carried out. Temperature behavior of the mean the refractive index n, ordinary n(0) and extraordinary n(e) ...
N-salicylidene anilines and their copper complexes: comparative investigations of mesomorphic, morphologic, thermotropic and thermodynamical properties
(Taylor & Francis Ltd, 2006)
In this work comparative studies of the mesomorphic and morphologic properties and thermal behaviour of new Schiff base N-salicylidene aniline ligands and the effects of Cu(II) additions on these properties have been carried ...
Optical refracting properties, birefringence and order parameter in mixtures of liquid crystals: Direct smectic A - Isotropic and reverse isotropic - Smectic A phase transitions
(Elsevier, 2022)
Due to the physical anisotropic and self-assembling nature, liquid crystalline materials holdvery important place in theoretical, experimental and applied physics. Besides, liquid crystals are important materials as working ...
