Isotropic Phases(各向同性相)研究综述
Isotropic Phases 各向同性相 - Close to the focus, the phase transition between nematic and isotropic phases (Tc = 331Κ for E7) is reached. [1] (Int J Eng Sci 98:153–182, 2015) for the case of isotropic phases, it was shown that given a new phase volume fraction and depending on average strain, the strain energy of a two-phase linear-elastic composite is minimized by either direct or inclined simple laminates, direct or skew second-rank laminates or third-rank laminates. [2] Since both activity and temperature affect the stability of the nematic, for active nematics in the stable regime the temperature can be tuned to observe static interfaces, providing an operational definition for the coexistence of active nematic and isotropic phases. [3] We use a hybrid method of lattice Boltzmann and finite differences to simulate flat and curved interfaces between the nematic and isotropic phases of a liquid crystal described by the Landau-de Gennes theory. [4] This system exhibits hexagonal and isotropic phases on heating. [5] In many lyotropic liquid crystals, the evolution of macroscopic anisotropic phases is mediated by tactoids, which are discrete ordered microdroplets existing in continuous disordered phases. [6] Summary Macroscopic manipulation of self-assembly in lyotropic systems, such as chiral nematic liquid crystals formed by cellulose nanocrystals, is kinetically hindered by the similarity between isotropic and anisotropic phases in composition and physical properties. [7] These include a gapped fractional quantum Hall state in close proximity to compressible and anisotropic phases, providing evidence for a delicate competition of a manifold of correlated states that are present at fractional fillings, and whose nature is yet to be fully understood. [8]靠近焦点，达到向列相和各向同性相之间的相变（E7 的 Tc = 331K）。 [1] (Int J Eng Sci 98:153–182, 2015) 对于各向同性相的情况，表明给定新的相体积分数并取决于平均应变，两相线弹性复合材料的应变能最小化通过直接或倾斜的简单层压板，直接或倾斜的第二级层压板或第三级层压板。 [2] 由于活性和温度都会影响向列相的稳定性，因此对于稳定状态下的活性向列相，可以调节温度以观察静态界面，从而为活性向列相和各向同性相的共存提供操作定义。 [3] 我们使用晶格玻尔兹曼和有限差分的混合方法来模拟Landau-de Gennes 理论描述的液晶向列相和各向同性相之间的平面和弯曲界面。 [4] 该系统在加热时呈现六方相和各向同性相。 [5] 在许多溶致液晶中，宏观各向异性相的演变是由 tactoids 介导的，tactoids 是存在于连续无序相中的离散有序微滴。 [6] 总结 易溶系统中自组装的宏观操作，例如由纤维素纳米晶体形成的手性向列液晶，在成分和物理性质上各向同性和各向异性相之间的相似性在动力学上受到阻碍。 [7] 这些包括紧邻可压缩和各向异性相的带隙分数量子霍尔态，为分数填充中存在的多种相关状态的微妙竞争提供了证据，其性质尚未完全理解。 [8]
