Muscles are biological actuators extensively studied in the frame of Hill's classic empirical model as isolated biomechanical entities, which hardly applies to a living organism subjected to physiological and environmental constraints. Here we elucid

True nature of the Curzon-Ahlborn efficiency

Autor: Christophe Goupil, Y. Apertet, Henni Ouerdane, Ph. Lecoeur

The Curzon-Ahlborn efficiency has long served as the definite upper bound for the thermal efficiency at maximum output power, and has thus shaped the development of finite-time thermodynamics. In this paper, we repeal the ruling consensus according t

International audience; We have studied the antiferromagnetic coupling at the interface of the La0.7Sr0.3MnO3/SrRuO3 bilayer as function of temperature. We measured the La0.7Sr0.3MnO3 magnetization reversal while the SrRuO3 magnetization is blocked d

We investigate the electrical transport and magnetic field dependence of nano-patterned La 0.7 Sr 0.3 MnO 3 devices. We find that the resistivity versus temperature dependence is the same as that observed in thin films, indicating that our nano-patte

International audience; High-quality all-oxide thin film metal–semiconductor junctions, fabricated of a half-metallic ferromagnet La$_{0.7}$ Sr$_{0.3}$ MnO$_3$ and of a niobium doped n-type semiconductor SrTiO$_3$ (SrTi$_{0.8}$Nb$_{0.2}$O$_ 3$) by
