TAPIR (compacT and modulAr Power modules with IntegRated cooling) Technology: Goals and Challenges

This paper deals with a new compact and modular technology for power module, with integrated cooling to reduce the global weight/volume of power converters by optimizing the volume of the heat sink. It is based on the modular assembly of elementary…

A thermal energy harvester using LaFeSi magnetocaloric materials

A thermomagnetic generator (TMG) using an Halbach structure as a field source and a first order LaFeSi magnetocaloric material (MCM) from Vacuumschmelze as active substance, is presented. The MCM, suspended on a cantilever beam self oscillates…

Effect of load sequence interaction on bond-wire lifetime due to power cycling

Experimental investigations on the effects of load sequence on degradations of bond-wire contacts of Insulated Gate Bipolar Transistors power modules are reported in this paper. Both the junction temperature swing (ΔTj) and the heating duration (tON…

La mécanique quantique relationnelle

Dans le domaine des fondations de la mécanique quantique (MQ), le consensus fait défaut. Un livre comme Helgoland, qui expose une interprétation des phénomènes quantiques connue sous le nom de mécanique quantique relationnelle (MQR), ne peut que…

High Performance Zinc Oxide Nanorod-Doped Ion Imprinted Polypyrrole for the Selective Electrosensing of Mercury II Ions

A biomimetic, ion-imprinted polymer (IIP) was prepared by electropolymerization of pyrrole at the surface of gold electrodes decorated with vertically grown ZnO nanorods. The vertical growth of the nanorods was achieved via an ultrathin aryl…
