Energetics of Brownian motors: a review
ثبت نشده
چکیده
We review the literature on the energetics of Brownian motors, distinguishing between forced ratchets, chemical motors – driven out of equilibrium by differences of chemical potential, and thermal motors – driven by temperature differences. The discussion is focused on the definition of efficiency and the compatibility between the models and the laws of thermodynamics. PACS 05.40.-a; 05.70.lw

Transport properties and efficiency of elastically coupled Brownian motors.
As models for biological molecular motors, Brownian motors have been studied recently by many workers, and their physical properties such as velocity, efficiency, and so on, have been investigated. They have also attracted much interest in an application to nanoscale technology. It is significant to study more complex systems, that is, coupled Brownian motors, in detail, since Brownian motors w...
متن کاملPerformance characteristics of Brownian motors.
Brownian motors are nonequilibrium systems that rectify thermal fluctuations to achieve directed motion, using spatial or temporal asymmetry. We provide a tutorial introduction to this basic concept using the well-known example of a flashing ratchet, discussing the micro- to nanoscopic scale on which such motors can operate. Because of the crucial role of thermal noise, the characterization of ...
متن کاملBrownian molecular motors driven by rotation-translation coupling.
We investigated three models of Brownian motors which convert rotational diffusion into directed translational motion by switching on and off a potential. In the first model a spatially asymmetric potential generates directed translational motion by rectifying rotational diffusion. It behaves much like a conventional flashing ratchet. The second model utilizes both rotational diffusion and drif...
متن کاملBrownian Carnot engine
The Carnot cycle imposes a fundamental upper limit to the efficiency of a macroscopic motor operating between two thermal baths1. However, this bound needs to be reinterpreted at microscopic scales, where molecular bio-motors2 and some artificial micro-engines3-5 operate. As described by stochastic thermodynamics6,7, energy transfers in microscopic systems are random and thermal fluctuations in...
متن کاملA Review of the Control Techniques for Brushless Direct Current Motors (REVIEW PAPER)
This paper surveys the literature of the brushless DC motor speed control techniques. The paper should prove useful to both researchers as well as practising engineers as a signpost to the current state of the art. Based on the review some further studies are suggested.
