Abstract: The invention relates to an aqueous alkaline cleaner solution for glass filler removal comprising: (a) at least one non-ionic surfactant selected from the group consisting of saturated branched or unbranched C5 to C12 carboxylic acid or salt thereof, wherein the concentration of the (a) at least one surfactant is from 0.9 to 1.7 g/L; (b) at least one surfactant selected from the group consisting of saturated branched or unbranched C5 to C12 alkyl having a negatively charged group selected from sulfate, sulfite, sulfonate, phosphate, phosphite and carbonate, and saturated C3-C8 alkyl amino carboxylate; (c) at least one compound having at least one hydroxyl group and at least one C—O—C group selected from the group consisting of alkoxylated C5-C12 alkanol and glycosidic C5-C12 alkanol; and (d) alkali metal hydroxide, wherein the concentration of the (d) alkali metal hydroxide is from 65 to 200 g/L; and a method for use.

Abstract: The invention relates to dining and/or serving cutlery made of a steel material which is formed from a ferritic core with an essentially martensitic boundary layer. In the dining and/or serving cutlery of the invention, the surface hardness of the boundary layer, determined according to the hardness test according to Vickers HV 3, is thereby greater by 30 to 300% than the lowest hardness of the core, likewise measured according to Vickers HV 3.

Abstract: A method for joining microstructured component layers and a method for manufacturing microstructure component layers and the microstructure component layer is provided. At least one multifunctional barrier coating is applied to the joining surfaces of a base material layer for the microstructured component layers. The layers are made of aluminum/aluminum alloys and/or copper/copper alloys, and/or noble steels. At least one solder/brazing coating is applied to each barrier coating. The coated base material layers comprising the component layers are stacked. The stacked component layers are joined by solder/brazing using heat. The melting temperature of the solder/brazing coating is higher after the heat joining than before same.

Abstract: Known manufacturing methods for microstructure components, in particular for microreactors, micro-heat exchangers, and micromixers, are not reliable enough to ensure that the component's pressure and corrosion resistance is high enough, that the component's tightness against fluid exiting from the component or fluid spilling over into adjacent microchannels is high enough, and that the microchannels have a sufficiently low flow resistance. In addition, known manufacturing methods are not cost-effective enough that the microstructured components can be employed in a wide variety of applications.
