Abstract

In this study, Nematic Discotic (N_D)-Nematic Biaxial (N_B)-Nematic Calamitic (N_C) phase sequences are investigated for some surfactant-based lyotropic mixtures. From the microscopic analysis point of view, the nematic phases, especially N_B one, are characterized by a methodology we developed to create a resultant image via composition of many microscopic textures (images). The resultant image permits recognizing the N_B phase bordered by two verticals imaginary lines contrasting two distinct colors. To consolidate our methodology, we simulated the interference colors chart of the samples for the first time via birefringence measurements performed by laser conoscopy technique. The simulated and experimental results are in good accordance.

在溶向性灾难向列相-双轴向列相-盘状向列相中双折射测量的模拟干涉色图。

本研究研究了一些表面活性剂基溶性混合物的向列盘状(ND)-向列双轴状(NB)-向列状Calamitic （NC）相序列。从微观分析的角度来看，向列相，特别是NB相，其特征是我们开发的一种方法，通过许多微观纹理（图像）的组合来创建合成图像。所得到的图像允许识别NB相位，该相位由两条垂直的想象线边界，对比两种不同的颜色。为了巩固我们的方法，我们首次通过激光conconscopy技术进行双折射测量，模拟了样品的干涉色图。仿真结果与实验结果吻合较好。

期刊介绍： EPJ E publishes papers describing advances in the understanding of physical aspects of Soft, Liquid and Living Systems. Soft matter is a generic term for a large group of condensed, often heterogeneous systems -- often also called complex fluids -- that display a large response to weak external perturbations and that possess properties governed by slow internal dynamics. Flowing matter refers to all systems that can actually flow, from simple to multiphase liquids, from foams to granular matter. Living matter concerns the new physics that emerges from novel insights into the properties and behaviours of living systems. Furthermore, it aims at developing new concepts and quantitative approaches for the study of biological phenomena. Approaches from soft matter physics and statistical physics play a key role in this research. The journal includes reports of experimental, computational and theoretical studies and appeals to the broad interdisciplinary communities including physics, chemistry, biology, mathematics and materials science.
