Abstract: A method of manufacturing a catalyst material includes the steps of: providing a body having an open-porous foam structure and comprising at least a first metal or alloy; providing particles, each of which particles comprising at least a second metal or alloy; distributing the particles on the body; forming a structural connection between each of at least a subset of the particles and the body; and forming an oxide film on at least the subset of the particles and the body, wherein the oxide film has a catalytically active surface.

Abstract: A device for producing concrete blocks, in particular concrete paving slabs, having a mold for filling with a concrete mixture, wherein the mold has at least one mold cavity for receiving the concrete mixture, and wherein the upwardly open mold cavity has walls as lateral boundaries, and wherein the at least one mold cavity can be filled with the concrete mixture by means of a filling device, and wherein the mold with the at least one mold cavity and the filling device are movable relative to one another in a filling axis. The filling axis is oriented obliquely to an axis of symmetry of the at least one mold cavity, with the result that preferably all of the walls of the mold cavity extend neither perpendicularly nor parallel to the filling axis, but at an angle.

Abstract: A method for the simulation of a propagation of electromagnetic beams, in particular light beams, is revealed, comprising the following steps of parametric specification of a first beam relative to a first boundary layer, specification of a first material into which the first beam should propagate after the first boundary layer, and determination of a reflection and/or transmission of the first beam relative to the first boundary layer on the basis of the first material and on the basis of a first model, wherein the first model comprises one or more functions which associate one or more reflection and/or transmission parameters with the first beam, and wherein the reflection and/or transmission parameter(s) associated with the first beam via the functions are determined.
