Abstract: A system for water electrolysis, for production of hydrogen and oxygen, including: at least one unit cell having at least two compartments, each compartment being configured to have an electrolyte solution flowing through the compartment, from at least one inlet port to at least one outlet port of the system, at least two being gas-producing porous electrodes, which are at least one anode and at least one cathode, located each in one compartment; at least one electrode being tridimensional; at least one hydraulic circuit, an element for ensuring a forced electrolytic solution flow in each compartment, and an element for applying a DC bias voltage to the electrodes.

Abstract: The invention relates to a mirror including a glass substrate covered with a silver layer, which is in turn covered with at least one paint layer, wherein the intensity ratio of the crystallographic orientations (111)/(200) within the silver layer is less than 5.0. Said mirror is characterized in that the silver layer has a correlation length (CLz) (111), as measured by X-ray diffraction using the Scherrer method (i.e., using the Scherrer equation) of greater than 27.0 nm.

Abstract: The present invention is about a method for filling an opening in an insulating layer in a fast and highly reliable way and can be used to fill openings such as trenches and via holes simultaneously. This method is based on the principle of reaction enhanced wetting and simultaneous seed layer formation. The idea is, in contrast to trying to avoid the TiAl3 formation, to use this reaction to its advantage for the creation of an ultra-thin continuous Al-containing seed layer. The latter allows a bottom to top fill during the subsequent Al-containing metal deposition. As a consequence, the filling process proceeds much faster and is production worthy.

Abstract: The invention concerns a process for preparing glass, more specifically glass powder or glass films, together with a process for conditioning the raw materials intended for preparing glass characterized in that raw materials are converted to freely flowing powder suitable for feeding to a plasma torch in which the powder is converted to glass.
