Proton field-cycling nucler magnetic resonance relaxometry in the smectic A mesophase of thermotropic cyanobiphenyls: Effects of sonication
(American Institute of Physics, 2004-07)
Field-cycling nuclear magnetic resonance (NMR) relaxometry was used to study the spin-lattice relaxation dispersion of selected standard smectic A liquid crystals at different temperatures. Relaxation features at both, in ...
Crystallography and the liquid crystal phase: a new approach to structural studies on a thermo-tropic smectic Schiff base
(Taylor & Francis Ltd, 2018-01)
In spite of the apparent contradiction between ‘liquid crystals’ (LC, materials exhibiting some degree of disorder) and ‘crystallography’ (a paradigmatic ordered kingdom), X-ray diffraction (XRD) studies make a substantial ...
Thermodynamics, transition dynamics, and texturing in polymer-dispersed liquid crystals with mesogens exhibiting a direct isotropic/smectic-A transition
(American Chemical Society, 2009-12-23)
Experimental and modeling/simulation studies of phase equilibrium and growth morphologies of novel polymer-dispersed liquid crystal (PDLC) mixtures of PS (polystyrene) and liquid crystals that exhibit a direct isotropic/smectic-A ...
Smectic Cu(II), Pd(II) and VO(IV) complexes: Synthesis, EPR and thermogravimetric studies
(TAYLOR & FRANCIS LTD, 1998)
The octadecanoate of N-(4-hexyloxyphenyl)salicylaldimine and the corresponding Cu(II), Pd(II) and VO(IV) complexes were synthesized and studied. The compounds were characterized by IR, H-1 NMR, elemental and thermal analysis ...
4'-[2-(2-Ethoxy-ethoxy)eth-oxy]-bi-phenyl-4-carboxylic acid: Correlation between its crystalline and smectic phases
(Wiley Blackwell Publishing, Inc, 2009-12)
The crystal structure of the dimeric title compound, C19H 22O5H, is dominated by a head-to-head hydrogen-bonding inter-action between centrosymmetrically related carboxyl groups in each monomer. The result is a dimeric ...
Conductivity of electronic liquid-crystalline mesophases
(Amer Physical SocCollege PkEUA, 2008)
Light sensitive antiferroelectric achiral copolymers
(ROYAL SOC CHEMISTRY, 2012)
Five copolymers were prepared by polymerization of azo-benzene methacrylate monomers in solution using AIBN as initiator. The mesophases were observed by a polarizing light microscope which showed tilted smectic C phases ...
Studies of first- and second-order phase transitions in LC methacrylic monomers based on the omega-hexyloxysalicylaldimine group
(TAYLOR & FRANCIS LTD, 2007)
The synthesis and phase characterization of two liquid crystalline methacrylic monomers based on the omega-hexyloxysalicylaldimine group with octyl and decyloxy chain substitutions is presented. The liquid crystalline ...
