It is known that for the description of the kinetics of processes of crystallization of melts of metals, low molecular weight materials, etc., the experimentally validated Kolmogorov-Avrami equation [45, 46] is often used, which for the above-mentioned symbols will have the form:
(31)
where – the value of the total mass of gas hydrates at the time t; z – constant rate of crystallization; n – coefficient dependent on the mechanism of formation and growth of crystals.

According to the author sustainable city logistics can be defined as a social, economic and environmental approach to “planning, coordinating and controlling processes taking place within the boundary of a given urban area and is related to physical movement of goods (i.e. raw materials, semi-products, goods and waste, etc.), people and information in a manner that will optimise costs, minimise congestion and improve quality of life” [16].

An important way to characterize the defect structure in materials is by means of self-diffusion.
But in nano materials, the most fundamental concept of bulk crystal is lost and so the hopping of atoms between defects and migrating atoms could not be easily visualized.
This is the reason for the development of ab initio and simulation methods for the nano materials.
Even though models are not unique, this model calculations for nano materials need lot of discussions, as given earlier.
