Abstract: A hollow body includes a wall of glass which at least partially surrounds an interior volume of the hollow body. The wall of glass has a wall surface which has a surface region. At least in the surface region the wall surface has a content of N in a range from 0.3 to 10.0 at-%, and at least 5 at-% Si.

Abstract: A method for producing an appliance component is provided. The appliance component has an operational front side and back side and has a substrate made of thermally tempered flat glass with a coating. The method includes the steprs of: a) providing a glass substrate made of thermally tempered glass with the dimensions of the appliance component; b) applying a preparation for producing an adhesion promoter layer onto a surface of the glass substrate, wherein the preparation is applied onto the surface of the glass substrate that forms the operational back side of the decorative panel; c) producing the adhesion promoter layer by polymerization of the preparation applied in step b); d) applying a preparation for producing an organic color layer onto the adhesion promoter layer produced in step c) by digital printing; and e) producing the organic color layer by polymerization of the preparation applied in step d).

Abstract: An assembly is provided that includes a ceramic converter for converting light having a first wavelength into light having a second wavelength, a metal-containing reflective coating, and a cooling element. The surface of the ceramic converter is at least partly coated with the metal-containing reflective coating. The coating dissipates the heat from the converter into the cooling element. The cooling element and the metal-containing reflective coating are connected to one another by a metallic solder connection.

Abstract: Substrates of glass or glass ceramic are disclosed which are coated with decorations, also methods for preparing such coatings are disclosed, wherein the decorations are optimized with respect to their acoustic characteristics in such a way that in particular when displacing cookware on induction cooking surfaces the subjective noise feeling is minimized, as possible.

Abstract: Solar modules are provided that include a front pane, an inter layer into which solar cells are embedded, and at least one back side foil, which increases the life span of the solar modules. The at least one back side foil is provided with holes having a density of at most 0.2 cm?2.

Abstract: A method of presenting training materials for training users with developmental dyscalculia or related learning difficulties includes determining a number or a numerical expression to present as part of training the user in developing internal maps to assist with overcoming a learning difficulty, whereby the user can increase a tendency to establish an internal neurological representation of numbers and numerical expression, wherein a numerical expression is a sequence of at least one number and at least one mathematical operator, generating a representation in a virtual space of an arrangement of numbers, including a number line and a representation of the number or the numerical expression, taking into account a resolution of the computer-controlled display that is to be used, and presenting to the user, using the computer-controlled display, a view of the virtual space showing the number line and the representation of the number or the numerical expression.
