摘要： A process for imparting bacteriostatic or bactericidal properties to the surface of an object, which consists in (a) providing an object of which the surface bears groups comprising at least one oxygen atom; (b) applying, to the surface provided in step (a), a coating based on polymers of polydopamine or a derivative thereof carrying at least one function —Y, where Y is a halogen atom or a function —N(R11)(R12) in which R11 and R12 are identical or different and are a hydrogen atom, an optionally substituted alkyl group or an optionally substituted aryl group; and (c) contacting the coated surface obtained after step (b) with a solution containing at least one dihalogen and at least one diamine at a temperature greater than ambient temperature, whereby a polyionene polymer-based coating is grafted covalently to said coated surface obtained after step (b).

摘要： An accumulator with a bipolar architecture that comprises two terminal current collectors, between which a stack of n electrochemical cells is disposed, with n being an integer at least equal to 2, wherein: —each electrochemical cell comprises a positive electrode, a negative electrode and an ion conducting membrane that is interposed between the positive electrode and the negative electrode and comprises a liquid electrolyte included in the electrodes and the ion conducting membrane; —the n electrochemical cells are separated from each other by n−1 bipolar current collectors; wherein the positive electrode and the negative electrode of each electrochemical cell are gel electrodes comprising a composite material comprising a polymeric matrix made of at least one gelling polymer (FF), an active electrode material and optionally one or more electronic conductive additives, the polymeric matrix trapping the liquid electrolyte.

摘要： A memory includes a memory cell including a planar electrode in a first plane; a floating electrode in a second plane, parallel to the first plane; a vertical electrode. The planar electrode includes a first part facing a first part of the floating electrode, the first part of the planar electrode and the first part of the second electrode being separated by a first layer of a first active material, the vertical electrode includes a part facing a second part of the floating electrode, the first part of the vertical electrode and the second part of the floating electrode being separated by a second layer of a second active material. The first active material forms a selector or a memory point and the second active material forms a memory point or a selector. The planar and floating electrodes not sharing any plane parallel to the first or second plane.
