OUT-OF-EQUILIBRIUM NANOSYSTEMS

English Français

In many circumstances, nanosystems are smart because they function out of equilibrium. This is the case for nanomechanical actuators using carbon nanotubes as their shaft, molecular motors, copolymerization processes such as DNA replication, nanometric chemical clocks, or electronic nanodevices. These nanosystems dissipate energy in nonequilibrium regimes, which need to be characterized for their transport and thermodynamic properties.
