Abstract: A method for producing a catalyst-coated polymer membrane for an electrolyser and/or a fuel cell includes steps including providing a glass-ceramic substrate and synthesizing a mesoporous catalyst layer on the glass-ceramic substrate. The steps include pressing a polymer membrane onto the glass-ceramic substrate coated with the catalyst layer at a first temperature T1, thereby producing a sandwich structure. The steps further include separating the sandwich structure. The catalyst layer is separated from the glass-ceramic substrate and adheres to the polymer membrane.

Abstract: The present disclosure relates to a method for the production of metal-containing spherically porous carbon particles. For this purpose, a carbon precursor is preferably polymerized with a structure-forming template in a solvent to form a polymer solution in a first step, the metal compound is added to the polymer solution in a second step and finally the metal-containing spherically porous carbon particles are formed in a third step by means of an aerosol spraying method. In addition, the present disclosure relates to a method for producing an ink and a use of the metal-containing spherically porous carbon particles as a catalyst.

Abstract: A removable accessory for a fencing mask provided with a mesh having an array of apertures is provided. The accessory can include a main body having a first surface, and a plurality of projections extending from the first surface of the main body. Each projection is configured to be removably insertable into an aperture of the mesh. Therefore, the accessory may be removably attached to the fencing mask, without damaging the fencing mask.

Abstract: The invention relates to a method for producing a catalyst-coated polymer membrane for an electrolyser and/or a fuel cell. In a first step, the method preferably comprises the provision of a glass-ceramic substrate. A mesoporous catalyst layer is then preferably synthesized on the glass-ceramic substrate. In a next step, a polymer membrane is preferably pressed onto the glass-ceramic substrate coated with the catalyst layer at a first temperature T1. This results in a sandwich structure. In a final process step, the sandwich structure is separated, the catalyst layer being separated from the glass-ceramic substrate and adhering to the polymer membrane. In addition, the invention relates to a polymer membrane which has been produced by the process of the type mentioned at the outset, and to an electrolyser or a fuel cell having such a polymer membrane.

Abstract: A computer implemented method for providing a service for a complex industrial system, the method including the steps of providing Bill of Materials, BoM, trees of system component instances of said complex industrial system; generating automatically a unified BoM data model by clustering matching nodes within the provided BoM trees; and performing the service for the complex industrial system based on the generated unified BoM data model is provided.

Abstract: The present invention relates to a method of producing porous metal oxide films on a substrate using template assisted electrostatic spray deposition (ESD). Thereby it is possible to produce both mesoporous and macroporous films which have a predefined pore morphology. In addition hierarchically structured meso- and macroporous films can be produced. The present invention also concerns the produced porous films and their use in catalysis, power storage, sensing and compound separation.
