I work on theoretical description of nonequilibrium phenomena in dense assemblies of nanoparticles. Recently we developed models of hydrodynamic separation of nanoparticles in narrow pores fabricated by silicon resin moulding [1]. Ve solve movement of dense suspensions of active coloid particles a strudy motility-induced phjase separation (MIPS) and jamming as a result of far-from-equilibrium nature of the system [2].
