METHOD OF DETERMINING DIRECTION OF MOVEMENT OF MOVING OBJECTS FROM INTERACTION SURFACTANT WITH LIQUID LAYER OVER DISPERSED MATERIAL Russian patent published in 2014 - IPC G01N13/00 B82B1/00 

FIELD: nanotechnology.

SUBSTANCE: invention relates to the field of evaluation of properties of dispersed materials and can be used for development of energy nanotechnologies in different fields of industry and fields of knowledge, as well as for development and management of self-organising systems, offers the opportunities to learn new principles of making technical devices. To determine the range of movement of moving objects, the direction of their movement, determining the number and size of particles in the sectors of the restrictive circle the object-preparation is used made of paper coated with a restrictive line with width of 5-6 mm in the form of a circle with a marked centre, the direction of the video camera location and divided into sectors with thin lines of the circle of the hydrophobic material. And in the marked centre of the restrictive circle a template is placed into which the particulate material is placed. Then in the restrictive circle the liquid under study is placed in an amount providing the thickness of the liquid layer over the material under study. Then a capillary is brought to its centre at a height of 1-6 mm, containing the surfactant, the video camera is switched on, which records of the changes on the surface. After completion of the process of moving the self-organising objects on the surface of the material under study the video camera is switched off, the plate with the object-preparation and the material under study in the template is left for drying without draining the water from the surface of the object-preparation. Then, using a microscope the number of the particles and their sizes near the restrictive circle is determined in each sector, according to which the direction is determined, in which the objects are predominantly moved, and an approximate combination of moving objects.

EFFECT: providing the ability to determine the range of movement of moving objects, the direction of their movement, determining the number and size of particles in the sectors of the restrictive circle.
