Abstract: The invention relates to a substrate holding and locking system for chemical and/or electrolytic surface treatment of a substrate in a process fluid and a corresponding method. The system comprises a first element, a second element, a reduced pressure holding unit and a magnetic locking unit. The first element and the second element are configured to hold the substrate between each other. The reduced pressure holding unit comprises a pump to reduce an interior pressure inside the substrate holding and locking system below atmospheric pressure. The magnetic locking unit is configured to lock the first element and the second element with each other. The magnetic locking unit comprises a magnet control and at least a magnet. The magnet is arranged at one of the first element and the second element. The magnet control is configured to control a magnetic force between the first element and the second element.

Abstract: The present invention relates to a composition comprising (a) an alkali metal salt and/or an alkaline earth metal salt of a C4 to C10 oxocarboxylic acid and (b) an alkali metal salt and/or an alkaline earth metal salt of an unsaturated or aromatic C6 to C10 carboxylic acid, wherein (a) is present in an amount of 20 to 95 wt.-%, based on the total mass of the composition, and (b) is present in an amount of 5 to 50 wt.-%, based on the total mass of the composition, wherein the composition is present in the form of a powder, methods of its manufacture and its use for inhibiting microbial growth in cosmetic, dermatological or personal care compositions.

Abstract: A building facade consisting of a building wall, an insulating layer comprising insulating elements, having a surface and disposed on the building wall, a facade cladding which is disposed at a distance from the building wall and from the insulating layer to form a rearventilation gap between insulating layer and facade cladding and a lock element provided for fire protection, which is disposed between neighboring insulating elements of the insulating layer. In order to further develop a building facade in such a manner that it can be manufactured simply and therefore cost-effectively without additional structural elements being provided, the invention proposes a generic building facade where the lock element is formed in one piece from fiber material, extends over the surface of the insulating layer in the direction of the facade cladding and exhibits a compressibility and/or flexibility aligned at least predominantly between building wall and facade cladding.
