Refractive and birefringent properties of 4-alkyl-4 '-oxycyanobiphenyls at direct and reverse phase transitions
(Taylor & Francis Ltd, 2017)
Studies of temperature behavior of the mean refractive index, ordinary and extraordinary refractive indices, and birefringence have been carried out for three nematogens. The thermo-morphologic properties of the biphasic ...
Lyotropic mesophase in amphiphile plus aliphatic alcohol mixtures with additions of water: mesomorphic, thermomorphologic, and optical refracting properties
(Springer, 2017)
Amphiphile + aliphatic alcohol lyotropic systems with addition of water can form micelles with normal, mixed, and inverse type. Such systems display various types of mesophases and exhibit interesting structural, physical, ...
Comparative Investigations of Light Transmission in Aligned and Non-aligned Textures of Homogeneous Mixtures of 4-n-alkyl-4'-Cyanibiphenyl Mesogens at Direct and Reverse smectic A <-> isotropic liquid Phase Transitions
(Springer, 2017)
The thermo-optical properties of various types of textures (the homeotropic, planar, and tilted aligned and non-aligned textures) in liquid crystalline materials with smectic A mesophase have been investigated. Investigations ...
Refractive and birefringent properties and order parameter of nematic liquid crystal at the direct and reverse nematic <-> isotropic liquid phase transition
(Natl Inst Optoelectronics, 2016)
Temperature dependences of the refractive indices, birefringence and molecular polarizability in large temperature interval and especially in the region of the direct nematic mesophase - isotropic liquid (for the heating ...
THERMOTROPIC, REFRACTING AND THERMO-OPTICAL PROPERTIES IN THREE HOMOLOGS OF 4-N-ALKYL-4 '-CYANOBIPHENYLS
(Lithuanian Physical Soc, 2015)
Investigations of temperature behaviour of the mean refractive index n, ordinary n(o) and extraordinary n(e) refractive indices, and birefringence Delta n have been carried out for three homologues of 4-n-alkyl-4'-cyanobiphenyls ...
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 ...
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 ...
