The methods developed in nonequilibrium statistical mechanics and the theory of nonequilibrium stochastic processes are applied to selected mesoscopic systems. Besides nucleation, we study nanometric bistable and oscillatory chemical systems , both theoretically and exparimentally (field ion microscopy & heterogeneous catalysis), the emergence of nanoscale patterns arising from the interference between nonequilibrium processes and equilibrium critical phenomena, self-organization in gels with mechanical response to autocatalytic chemical reactions, mean-field versus master equation descriptions, emergence of anomalous inhomogeneous fluctuations. Of special interest is also the smart behavior of nanosystems as a consequence of their functioning out of equilibrium with applications to nanomechanical actuators using carbon nanotubes as their shaft, molecular motors, copolymerization processes such as DNA replication, or electronic nanodevices. Energy dissipation in nonequilibrium regimes in relation with their transport and thermodynamic properties is also analyzed.
