The microheterogenous and nanoheterogenous (mesoscopic) liquid-liquid systems may be concisely called the small systems. They comprise the micro- and nanodomains, described in colloidal chemistry as a variety of structures, e.g., micelles, rods, disks, vesicles, microemulsions, monolayers, and Langmuir Blodgett layers [6,17 19,70]. 

A CDF is interpreted in the same way as a CLD or an IDF. All these functions exhibit the probability distributions of domain size and arrangement. Clearer than a CLD is the IDF, because it does not contain an orientation average but exhibits the topology in a selected direction. Clearer than an IDF is the CDF, because it visualizes the nanodomain topology in space, i.e., in more than one direction. 

Perfection of Structure in Nanostructured Materials. An aim of modern nanotechnology is the fabrication of materials with highly perfect structure on the nanometer scale. The distortion of such nanostructured materials can be studied by SAXS methods. Frequently the material is supplied as a very thin film with predominantly uniaxial correlation among the nanodomains. Under these constraints the nanodomains are frequently arranged in such a way that the normal to the film is a symmetry axis rotation of the film on the sample table does not change the scattering (fiber symmetry). 

Preparation of the composite materials with the FAU and BEA nanodomains has been reported previously [3,4]. The procedure was based on the impregnation of the parent materials with concentrated template solutions and subsequent recrystallization in the hydrothermal conditions. Amorphous aluminosilicates of chemical composition 13%Al20387%Si02 (13A187Si) and 6%Al20394%Si02 (6A194Si) were used as the parent materials for the FAU and BEA composites, respectively.

Among other specific applications of PTs as light-emitting materials, it is necessary to mention microcavity LEDs prepared with PTs 422 and 416 [525,526] and nano-LEDs demonstrated for a device with patterned contact structure, and PT 422 blended in a PMMA matrix that emits from phase-separated nanodomains (50-200 nm) [527,528].

Note 2 The term domain may be qualified by the adjective microscopic or nanoscopic or the prefix micro- or nano- according to the size of the linear dimensions of the domain. Note 3 The prefixes micro-, and nano- are frequently incorrectly used to qualify the term phase instead of the term domain hence, microphase domain , and nanophase domain are often used. The correct terminology that should be used is phase microdomain and phase nanodomain.

Abstract Spin-orbit coupling is a crucial parameter controlling the spin relaxation rate in solids. Here we review recent theoretical results on the randomness of spin-orbit coupling in two-dimensional structures and show that it exists in a form of random nanodomains. The spin relaxation rate arising due the randomness is analyzed. The random spin-orbit coupling leads to a measurable intensity of electric dipole spin resonance, that is to spin-flip transitions caused by the electric field of an electromagnetic wave.
