We investigate the phase-transition behavior of ionic liquid crystals, namely 1-methyl-3-alkylimidazolium tetrafluoroborate, [Cnmim]BF4, confined in cylindrical nanopores using differential scanning calorimetry, x-ray scattering, and dielectric relaxation spectroscopy. Here, n is number carbon atoms alkyl part this crystal. For = 10 12, isotropic phase changes to smectic then a metastable for cooling process. During subsequent heating process, via crystalline phases. The transition...
<title>Abstract</title> The electroconvection of liquid crystals is a typical example dissipative structure generated by complicated interactions between three factors: convective flow, structural deformation, and the migration charge carriers. In this study, we found that periodic deformation cholesteric crystal propagates in space, like wave, under an alternating-current electric field. existence convection carriers was confirmed flow-field measurements dielectric relaxation spectroscopy....
