Peculiarities of thermo-morphologic and thermotropic transformations of heterophase regions: nematic <-> isotropic phase transition in 4-n-Alkyl-4 '-cyanobiphenyl mesogens
(Natl Inst Optoelectronics, 2019)
Important peculiarity of phase transitions in liquid crystalline materials is availability of the heterophase regions, in which low temperature and high temperature phases simultaneously take place. In this work, peculiarities ...
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. ...
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
(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)
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) ...
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 ...
