A self-assembled DNA-based molecular device is described which can be switched between three distinct mechanical states. The device consists of two supramolecular “arms” connected by a hinge. The arms can be in a closed, relaxed, or stretched configuration. The operation of the device is monitored by fluorescence resonance energy transfer. Variations in the design of the device have a strong influence on the operation kinetics of the device.© 2002 American Institute of Physics.

    A six-temperature kinetic model for a CO2-N2-He system is used to describe the dynamic processes of a mechanical Q-switched CO2 laser that is set up using a fast chopper. We put special emphasis on the effect of dynamical parameters on the laser intensity. It takes into account the effects of...
