摘要： The present invention relates to compositions for chemical-mechanical polishing comprising A 0.01 % to 40 % by weight based on the total amount of the composition of abrasive particles of at least one porous metal-organic framework material, wherein the framework material comprises at least one at least bidentate organic compound which is coordinately bound to at least one metal ion; B 40 % to 99.8 % by weight based on the total amount of the composition of a liquid carrier; and C 0.01 % to 20 % by weight based on the total amount of the composition of a polishing additive component. The invention further relates to the use of said composition as well as methods for chemical-mechanical polishing of a surface with the aid of said compositions.

摘要： The invention relates to a gas-tight multilayer composite tube which has a heat transfer coefficient of > 500 W/m
2 /K and contains at least two layers, one layer made of a nonporous monolithic oxide ceramic and one layer made of an oxide fiber composite ceramic, and relates to a connection piece containing at least one gas-conducting metal line, some regions of which overlap at least two ceramic layers in the longitudinal direction of the composite tube, wherein one ceramic layer contains a nonporous monolithic ceramic, and the other ceramic layer contains a fiber composite ceramic. The invention also relates to the use of the multilayer composite tube as a reaction tube for endothermic reactions, jet tubes, flame tubes, or rotary tubes.

摘要： The invention relates to a method for producing membranes coated with a catalyst on both sides for electrochemical devices, with the following steps: A) producing a first semifinished product by applying a first ionomer layer onto a first support, applying an anode catalyst layer onto the first ionomer layer while using a first catalyst ink, and drying the anode catalyst layer; B) producing a second semifinished product by applying a second ionomer layer onto a second support, applying a cathode catalyst layer onto the second ionomer layer while using a second catalyst tint, and drying the cathode catalyst layer; C) removing the first and second supports from the first or second ionomer layer and, joining the first semifinished product to the second semifinished product by joining the first ionomer layer to the second ionomer layer.
