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 ...
Study of mesomorphism, thermotropic properties and pitch in new chiral smectogenic imine compounds
(Elsevier, 2015)
We report the thermotropic, thermo-morphologic and structural properties of four homologs of (S)-5-alkyloxy-2-[{4-(2-methylbutoxy)phenylimino}methyl]phenol liquid crystalline salicylaldimine compounds, which are firstly ...
Texture transformations and thermo-optical properties of nematic mesogen at nematic-isotropic liquid phase transition
(Elsevier, 2014)

Phase states and thermomorphologic, thermotropic, and magnetomorphologic properties of lyotropic mesophases: Sodium lauryl sulphate-water-1-decanol liquid-crystalline system
(Amer Physical Soc, 2010)
Phase states in sodium lauryl sulphate-water-1-decanol lyotropic liquid-crystalline system have been investigated for different temperature ranges. The dependence of triangle phase diagram types, phase boundaries, and ...
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 ...
