The article deals with the issues of dispersion of heterogeneous liquids by spray nozzles in order to divide them into components. The influence of various parameters on the size of the droplets obtained is investigated. For the mathematical description the probabilistic approach is applied, which allows to obtain a differential function of the particle size distribution, which can form the basis of the engineering method of calculation of this class of separators. An expression for determining the average value of the angular velocity of the internal flow is compiled. These dependences allow us to calculate the most probable value of the angular velocity corresponding to the decay of complex drops into secondary ones, which are the drops of the initial liquids.

The article deals with the issues of impact interaction of particles with layers of dispersed material of different thickness. The influence of the interaction velocity and the thickness of the substrate on the appearance and structure of the collision result is investigated. It is established that at low speeds there is a crater formation while the particle is on the substrate surface. With the growth of the interaction rate, the formation of a crown is observed, and particles penetrate into the substrate material. Experimentally determined the values of the velocity and thickness of the substrate, corresponding to the beginning of the formation of the crown.

In this article is reviewed the nature of organic hybrid nanocomposites. Promising directions in the field of organic hybrid nanocomposite materials will be methods for the synthesis of multicomponent materials, as well as the type of "net net" and "host-guest". The fundamental problem with the chemistry and physics of nanocomposites is dependent "structure-property". Solving this problem will move from research materials to their purposeful design.
