Abstract: The present invention relates to an electrochromic device having controlled infrared reflection, in particular of the electrically controllable type, comprising, between a carrier substrate (1a) transparent in the infrared range and a counter-substrate (1b), a multilayer stack. The device is characterized in that this multilayer stack comprises, in succession: a) a metal grid (3) transparent in the infrared range, forming a first electrode; b) an electrochromic functional system (5) comprising a layer (EC1) of an ion-storage first electrochromic material, at least one layer (EL1, EL2) having an electrolytic function, and a layer (EC2) of a second electrochromic material; c) a metal layer (7) capable of reflecting the infrared radiation, forming a second electrode; and d) a lamination interlayer (9) made of a thermoplastic polymer.

Abstract: The invention relates to an active device having variable energy/light transmission properties (100) comprising an active system (1, 12) between a protective substrate (2) and a protective cover (3), selected from an essentially inorganic electrochromic system, a light valve system, a liquid crystal system, a gasochromic system, a thermochromic system, means leakproof to liquid water and/or water vapor, a surround (50) made from at least one metal based part (5a, 5b) on the periphery of the device, the surround being assembled with the cover and with the substrate by assembling means (61? to 64?) forming at least part of the means leakproof to water vapor.

Abstract: The subject of the invention is an essentially ceramic target for a sputtering device, especially for magnetically enhanced sputtering, said target comprising predominantly nickel oxide, the nickel oxide NiOx being oxygen-deficient with respect to the stoichiometric composition.

Abstract: The subject of the invention is an electrically controllable device having variable optical and/or energy properties of the electrochromic type, which comprises a functional film consisting of a layer or a stack of layers which is placed between two external substrates which meet the following criteria:
