Abstract: Catalytically-active metallic glasses containing at least one element from a subgroup of the periodic system and at least one element from a main group of the periodic system. Process for the production of catalytically-active metallic glasses where the metallic glass is produced from at least one element from a subgroup of the periodic system and at least from one element from a main group of the periodic system. The metallic glasses are activated by self-activation or by an oxidative and/or reductive treatment. The catalytically-active metallic glasses can be used as hydration, oxidation or isomerization catalysts.

Abstract: Juxtaposed nozzle openings apply the same or different melts to the surface of a moving cooler surface for producing thin metal strips or foils with a considerable width. The nozzle openings can be staggered in the direction of movement of the cooler surface and apply different materials to produce a metal strip with juxtaposed and sharply defined regions with different characteristics. Amorphous or mixed amorphous/crystalline, or solely crystalline material structures can also be produced. Alternatively, different cooling capacities on different cooler surface areas and different structuring of different cooler surface areas permit the melt to solidify on the cooler surface such that the strips or foils obtained have adjacent regions with different metallic and/or geometrical structures. By geometrical configuration of the cooler surface, foils with a structured surface or with shape-limited individual regions can be used for mass production of small parts from sheet or strip material.

Abstract: An electro-optical cell, more particularly for display purposes, which comprises a working electrode having an intercalatable layer structure, especially graphite, a counter-electrode, an ion conductor disposed between the two electrodes and, if desired, a reference electrode. On application of an electric voltage, ions from the ion conductor are inserted into the layer structure, whereby or visible, optical change on the surface of the electrode is effected.
