 The object of research - complex micro-mechanical many-particle materials in granular phases. The focus of the work is to develop theoretical models of soft matter objects, in particular, granular materials , their structurisation and physical properties and also their applications in relevant environmental safety technologies. Research methodology include theoretical and numerical modeling, physical experiment (on the laboratory bases of organizations-collaborators). For one-dimensional inhomogeneous power chain with nonlinear Hertzian contacts the multimode wave dynamics in the form of convolutions of cylindrical waves and resonant modes has been discovered. The Kirkwood-Buff theory and Carnahan-Starling - Mansori model of solid spheres, has been effectively used(for the first time) for universal theoretical description of empirical data on the compaction and compressibility of a binary mixture in the full range of values of the volume (or molar) fraction. The hybrid levitation-electrophoretic model of micro-mechanical drift motion in external inhomogeneous electric field has been proposed as a theoretical basis of the technology of highly efficient fine-dust evacuation from dust-contaminated surfaces with complex morphology. The technology of radioactive contamination by use graphen oxide in a foam fractions are investigated The results of research were used in writing monographs, articles in scientific journals, materials of lecture courses, qualification works and thesis, and also has been included in joint research programs with partner organizations.
