Abstract: A device for sensing a magnetic field, comprising a closed superconducting loop configured to collect a magnetic field to be sensed, hereinafter external magnetic field, the closed superconducting loop having a path width (wp) and being provided with a constriction having a width (wc) narrower than the path width, the constriction generating a non-uniform magnetic field, hereinafter internal magnetic field, in response to the external magnetic field, a vibrating mechanical oscillator coupled to, or formed by the constriction and responsive to the internal magnetic field, and a detector configured to detect deflection or vibration of the mechanical oscillator and providing a signal indicative of the deflection or vibration.

Abstract: Microelectromechanical sensor comprising a fixed part and a mobile part suspended from the fixed part such that the mobile part can move at least in an out-of-plane displacement direction, the fixed part comprising at least first electrodes extending parallel to the displacement direction of the mobile part, the mobile part comprising a seismic mass and at least second electrodes extending parallel to the out-of-plane displacement direction, the first electrodes and the second electrodes being located relative to each other so as to be interdigitated, in which the second electrodes are directly connected to the inertial mass and only part of the face of each mobile electrode is facing an electrode fixed at rest.

Abstract: A new process is described for the preparation of a 2-aryl-propionic acid, such as for instance 2-[4-(2-methyl-propyl)phenyl]propionic or 2-(6'-methoxy-2'-naphthyl)propionic acid, through hydrogenation of a complex salt which consists of the mono- and/or di-valent anion of the corresponding 2-hydroxy-2-aryl-propionic acid, a di- or tri-valent metal cation, such as for instance Al(+3), Fe(+3), Zn(+2), or Mg(+2), and optionally other anonic or neutral ligands.This new process is particularly advantageous in that the starting salt can be obtained directly via electrocarboxylation of the corresponding aryl methyl ketone, e.g. 4-(2-methyl-propyl)acetophenone or (6-methoxy-2-naphthyl) methyl ketone, with metal anodes which dissolve during the electrolysis.
