Abstract: A method for controlling a charging signal for charging a rechargeable battery cell, which is based on a dynamic electrochemical model using a functional or tabular relation for computing a maximum charging value for the charging signal. During charging, constraints of a constraint model are satisfied for a charging signal smaller than or equal to this maximum charging value. A battery cell not at an end-of-charge condition is charged with a closed-loop charging method, repetitively performing: i) measuring measurable signal(s) of the battery cell, ii) estimating state variable(s) of the model using a state observer algorithm, with the measured measurable signal(s) as input, iii) computing the maximum charging value using the functional or tabular relation with the estimates of the state variable(s) as input, and iv) applying to the battery cell a charging signal equal to or lower than the maximum charging value. Also, a charging device implementing the method.

Abstract: The invention relates to acoustic management, on an aircraft turbomachine (3,12) or on a nacelle (1,10), via a panel (30,32). On a support (38) is reserved a recess (34), recessed with respect to a surrounding general surface (36) for contact with moving air. The recess (34) is adapted to receive the panel, as another so-called surface for contact with moving air. The support (38) and/or the panel comprise removable connecting elements for, in the recess (34), mounting it removably with respect to the support, the panel being an acoustic panel or a non-acoustic panel.

Abstract: A method for manufacturing a part by additive manufacturing, the part to be manufactured including at least one portion to be held forming an angle of less than 45° with respect to a building direction of the part to be manufactured, the portion to be held having a first lateral surface and a second lateral surface opposite each other, the method comprising the steps of: providing a digital model of the part to be manufactured, adding to the digital model at least one holding element positioned on one side of the portion to be held, so as to be in contact with said first lateral surface or said second lateral surface.

Abstract: A process is disclosed for the recovery of valuable metals from oxidic ores, in particular from polymetallic nodules. The process is suitable for the recovery of Cu, Co, Ni, Fe, and Mn, which are the main metals of interest in such polymetallic nodules. The present process is, among others, characterized by the handling of Fe, which is dissolved and kept in solution until the step of crystallization rather than removed at an earlier stage. A mixed Mn—Fe residue is obtained, which, after thermal treatment, provides a Mn—Fe oxide that is suitable for the steel or for the manganese industry. Excellent Cu, Co and Ni yields are obtained, while Fe is leached and valorized together with Mn.

Abstract: The present disclosure concerns a process for the recovery of valuable metals from polymetallic nodules. A two-stage process using SO2 in an acidic aqueous media is disclosed. In a first step, performed in mildly acidic conditions, Mn, Ni, and Co are dissolved; in a second, more acidic step, Cu is dissolved. Under these conditions, the leachate of the first step contains most of the Mn, Ni, and Co, while being nearly Cu-free. The Ni and Co are precipitated as sulfides; the Mn can be recovered as sulfate by crystallization. Cu, which is leached in the second step, is secretively precipitated, also as sulfide.
