Resumo:	Title screen Local laser heating of the liquid film leads to simultaneous self-organization of both cellular convective structures and a cluster of micron-scale particles. The cluster is formed on the free surface of the layer and consists of hexagonal structures with a size of 50-100 ?m. The height of the liquid film (0.5 mm) is ten times the diameter of the convective cells. Experimental data on the distribution of particle sizes and sizes of hexagonal cells in the cluster are presented. The cluster shape may be either a circle with a diameter of 110-140 ?m, or an ellipse. Due to the instability of the velocity field, the toroid is not formed, and convective cells are formed only near the heating center. Self-organization of a cluster of particles and cellular structures using local heating can be effectively used to create new promising materials, as well as in micro-biology and medicine.
