We report on the first ion-implanted dielectric electroactive polymer actuator that was successfully microfabricated and tested. Ion implantation is used to make the surface of the polymer locally conducting. Implanting the compliant electrodes solves the ...
A low temperature method of bonding two polymer sheets (2, 3) without adhesive, at least one of said polymer sheets comprising a microstructure (1) or a network of microstructures, comprises the steps of treating at least a portion of one surface of one of ...
L'émergence de procédés de gravure profonde performants (vitesse, anisotropie, uniformité…) de matériaux tels que le silicium (Si), la silice (SiO2) et certains polymères repose sur: • Le développement d'équipement de gravure permettant le contrôle indépen ...
Inline conversion measurements in chem. reactions are in general and esp. in polymn. reactions necessary for process monitoring and control. For polymn. monitoring, the sound propagation (UPV) can be related to the texture of the bulk with a high accuracy. ...
Abstract—In this paper, a model is proposed to analyze the influence of timing imperfections on ultra-wide bandwidth (UWB) time-hopping spread-spectrum (TH-SS) signaling schemes, where N pulses are coherently added to increase the received signal-tonoise r ...
A process for prepg. a water sol. polymer comprises: providing a polymn. reaction mixt. comprising one or more polymerizable ethylenically unsatd. monomers; polymg. the ethylenically unsatd. monomers; and adding to the reaction mixt. during polymn. one or ...

An alternative to the classical acid-base regeneration of chelating resins loaded with heavy metals is investigated. The new process consists in recovering the heavy metals with recyclable soluble complexing agents. The semiclosed reactor includes a fixed ...
