Abstract: The present invention relates, in particular, to a method for generating neutrons comprising at least the series of steps that consists of: a) placing at least one beam of electrons and at least one beam of nuclei selected from among protons, deuterons and tritons into a predefined spin state and/or an interference state; and b) causing said at least one beam of nuclei and said at least one beam of electrons to collide.

Abstract: The invention relates to a method for producing and/or capturing neutrons, including the following steps: a) exposing nuclei selected among protons, deuterons and/or tritons to an electric field in order to extract said nuclei and to direct said nuclei thus extracted towards a target (20) containing free electrons; b) for example, exposing said nuclei to a spatial and/or temporal gradient of a first magnetic field so as to give a predefined orientation to the magnetic moments of the nuclei; c) either exposing the target to a second magnetic field so as to give a predefined orientation to the magnetic moments of the free electrons of the target; d) or using an electron-donor superparamagnetic material so that the electrons of the free layers of these materials are oriented in preferred directions generated by the orientation of the resulting magnetic moment of the superparamagnetic material; e) for example, in the case of using a superparamagnetic material, not exposing the proton beam and/or the target to the

Abstract: A three-chamber electrochemical cell comprises a central chamber, first and second chambers, and a central part for conveying a fluid solution into and out from the central chamber, the central part being symmetric with respect to a mid-plane of the cell. First and second electrodes of the cell are in surface contact with, respectively, first and second membranes. The first and second electrodes are produced from a porous electrically conductive material that absorbs mechanical stresses due to a first pressure differences between the first side chamber and the central chamber, and a second pressure difference between the second side chamber and the central chamber. The first and second electrodes are produced from a material including micrometer-sized metal beads compacted with one another leaving interstices between the beads, which form the pores of said electrodes.
