Abstract:
The present invention relates to a culinary article (1) comprising a metal substrate (2) having a concave inner face (21) intended to be placed on the side of food which can be introduced into said article (1) and a convex outer face (22) intended to be placed facing a heat source, said inner face being coated in succession, starting from said substrate (2), with a hard enamel base (3), which is rough and contains no lead or cadmium, and then with a non-stick coating (4) covering said hard layer (3). The present invention also relates to a method of manufacturing such an article (1).
Abstract:
Disclosed is a method for structuring a surface, i.e. forming at least one system of designs having a characteristic size on at least one partial surface of a substrate that has a glass function. Said method is characterized in that a solution comprising at least one precursor of a material to be deposited is decomposed within a flame at atmospheric pressure, said flame being directed to said partial surface such that a mask is deposited thereon in the form of a plurality of nodules made from said material, and the mask made from said material is engraved.
Abstract:
The present invention relates to a hydrophilic photocatalyst and a process of preparation thereof to obtain a titanium dioxide (TiO2) layer of an anatase structure having an excellent photocatalystic effect on a chromium substrate, and in particular to a hydrophilic photocatalyst and a process for preparation thereof including: coating a titanium dioxide (TiO2) layer of an amorphous form on the substrate while maintaining the temperature of the substrate below 200 °C , coating the TiO2 layer of a pure anatase structure on the TiO2 layer of the amorphous form, and coating a silicon dioxide layer on the TiO2 layer of the pure anatase structure, wherein a super-hydrophilic property having a contact angle below 10 degrees showing a photocatalystic effect by ultraviolet irradiation appears within 1 hour after UV irradiation and a hydrophilic property having a contact angle below 20 degrees between the substrate and water drops is maintained for 18 hours.
Abstract:
The invention concerns an organic light-emitting device comprising: a substrate, in particular a transparent substrate, a first electrode and a second electrode on a common surface of the substrate, the first electrode being at least semi-transparent or transparent, a light-emitting layer interposed between the first and second electrodes. The invention is characterized in that the first electrode comprises an electroconductive diffusion layer having not less than 2% blur. The invention also concerns the use of an electroconductive diffusion layer having not less than 2% blur as electrode nearest to the substrate of an organic light-emitting device.
Abstract:
La présente invention concerne un substrat, en particulier un substrat verrier, comportant un revêtement comportant au moins une couche minérale telle que les oxydes, oxynitures et nitrures de métaux, destiné à recevoir un traitement de surface organique hydrophobe, et concerne ledit substrat comportant au moins une couche minérale et une couche hydrophobe organique. On a constaté que la couche minérale a pour effet de prolonger la durée de vie du revêtement organique car les propriétés hydrophobes du substrat revêtu au préalable de la couche minérale sont maintenues dans le temps plus longtemps que lorsque le traitement organique est directement déposé sur le substrat. Le substrat revêtu selon l'invention peut servir à la fabrication de portes de douche, ou de vitrages architecturaux ou automobiles.
Abstract:
Dans un procédé de réalisation d'un revêtement sur un support, en particulier sur une surface de verre, dans lequel un oxyde métallique est déposé en couche mince sur le support, cette couche mince subissant une opération de gravure pour rendre sa surface rugueuse, un deuxième revêtement susceptible d'adhésion à la couche dudit premier oxyde métallique étant ensuite appliqué sur la surface rendue rugueuse, on dépose selon l'invention un premier oxyde métallique ou oxynitrure métallique dopé avec au moins un deuxième oxyde métallique ou oxynitrure métallique, le deuxième oxyde métallique ou oxynitrure métallique étant réparti dans la couche déposée. Lors de l'opération de gravure, on utilise un gaz activé par plasma qui enlève au moins un deuxième oxyde métallique ou oxynitrure métallique moins que le premier oxyde métallique ou oxynitrure métallique pour, après la gravure, former sur la surface des irrégularités en relief constituées d'au moins un deuxième oxyde métallique ou oxynitrure métallique.
Abstract:
The invention concerns visual marking of heat-treated substrates, in particular tempered glass panes, by modifying a marking layer deposited on one surface of the substrate, visually indicating the heat treatment, which consists in producing on the substrate surface a rough marking zone such that the marking coating deposited thereon exhibits an intimate and adherent bonding which cannot be totally removed with mechanical means.
Abstract:
The present invention relates to methods for forming textured surfaces in a polymeric surfaces. Moreover, the present invention relates to methods for forming textured surfaces in a polymeric surfaces and faithfully replicating the textured surfaces in the surfaces of sol-gel films on the surfaces of very hard materials, e.g., of glass, ceramic, or glass-ceramic substrates.
