Abstract: A sensor element for gas sensors is described for determining gas components of a gas mixture, especially in exhaust gases of internal combustion engines, having at least one electrochemical measuring cell and at least one porous layer that is exposed to the gas mixture. The porous layer contains palladium, platinum, ruthenium, an alkali metal and/or an alkaline earth metal, the platinum being contained in the porous layer at a minimum concentration of 1.5 wt. %. Furthermore, a method and an impregnating solution are described for producing the sensor element.

Abstract: A catalyst material is provided for treating products created during combustion which is developed for the catalytic conversion of carbon-containing particles, the catalyst material being applied onto a carrier and the catalyst material including cerium as one catalyst component. In order to provide a catalyst material, using which the catalytic conversion of carbon-containing particles is able to be improved, the catalyst components have at least one additional catalyst component besides cerium, the proportion of cerium amounting to at least 92 mol-% with respect to the entire quantity of the catalyst components. A method is also provided for preparing a catalyst material.

Abstract: A device for analyzing a materials library includes at least one radiation source for electromagnetic radiation, which is positioned in front of the materials library, and at least two flat detectors operating in parallel, which are operable using high-sensitivity resolution and of which one is sensitive to electromagnetic radiation of a first wavelength range and the other is sensitive to electromagnetic radiation of a second wavelength range. Moreover, a method for analyzing a materials library in which the materials library is simultaneously tested using at least two methods in which electromagnetic radiation of different wavelength ranges is used.
