Abstract: A cathodic subassembly for an electrochromic system, suitable for being deposited on top of a substrate having a glass function, includes a first transparent conductive layer, and a working electrode, arranged on top of the first transparent conductive layer, wherein the working electrode is suitable, by virtue of its chemical composition, for being functional after thermal tempering.

Abstract: The present invention relates to an article comprising at least one glass-ceramic substrate, in particular a plate, intended, for example, to cover or receive at least one heating element, said substrate exhibiting, in at least one zone, a surface roughness such that the characteristic dimensions of the patterns forming said roughness are between 2 and 100 ?m. The present invention also relates to an advantageous process for producing said substrate.

Abstract: A transparent diffusive OLED substrate includes (a) a transparent flat substrate made of mineral glass having a refractive index of between 1.45 and 1.65, (b) a rough low index layer including mineral particles, the mineral particles being attached to one side of the substrate by means of a sol-gel mineral binder, the mineral particles near, at or protruding from the mineral binder's surface creating a surface roughness characterized by an arithmetical mean deviation Ra comprised between 0.15 and 3 ?m, the mineral particles and mineral binder both having a refractive index of between 1.45 and 1.65; (c) a high index layer made of an enamel having a refractive index comprised between 1.8 and 2.1 covering the rough low index layer.

Abstract: The invention relates: to a process for forming a texture on a substrate, comprising: depositing a deformable layer on the substrate; bringing this deformable layer into contact with the textured face of a daughter stamp; introducing the coated substrate and the daughter stamp into a pouch made of an impermeable material; introducing the pouch and its contents into a hermetic vessel; evacuating air from the vessel until a pressure at most equal to 0.5 bar is reached; sealing the pouch before reintroducing air into the vessel; introducing the sealed pouch and its contents into an autoclave; applying a pressure comprised between 0.5 and 8 bar and a temperature comprised between 25 and 400° C.
