  The heterogeneity among interacting dynamical systems or in the pattern of
interactions observed in real complex systems, often lead to partially
synchronized states like chimeras or oscillation suppressed states like
inhomogeneous or homogeneous steady states. In such cases, recovering
synchronized oscillations back is required in many applications but is a real
challenge. We present how synchronized oscillations can be restored by tuning
the dynamical time scales of the system. For this we use the model of a
multiplex network where first layer of coupled oscillators is multiplexed with
an environmental layer that can generate various possible chimera states and
suppressed states. We show that by tuning the time scale mismatch between the
layers , we can revive synchronized oscillations in both layers from these
states. We analyse the nature of the transition to synchronization and the
results are verified for two- and three-layer multiplex networks.
