    Abstract: A process for the production of a carbon supported catalyst, which comprises the following steps: (a) precipitation of at least one metal oxide onto a surface of a carbon-comprising sup¬ port by preparing an initial mixture, comprising the carbon-comprising support, at least one metal oxide precursor and an organic solvent, and spray-drying of the ini¬ tial mixture to obtain an intermediate product, (b) loading of noble-metal-comprising particles onto the surface of the intermediate product in a liquid medium by deposition, precipitation and/or reduction of a noble- metal-comprising precursor with a reducing agent, (c) heat treatment of the catalyst precursor resulting from step (b) at a temperature higher than 400°C.

    Abstract: In welding plastics parts using laser radiation of a wavelength outside the visible range, in which the bonding region of one of the parts contains a visibly transparent and colorless material that absorbs the laser radiation, the material comprises nonionic compound(s) resistant to laser radiation and with a thermal stability of not less than 300[deg]C, selected from polycyclic organic compounds, doped tin oxides and the hexaborides of lanthanide and alkaline earth metals. In welding plastics parts using laser radiation of a wavelength outside the visible range, in which the bonding region of one of the parts contains a visibly transparent and colorless material that absorbs the laser radiation, the material comprises nonionic compound(s) resistant to laser radiation and with a thermal stability of not less than 300[deg]C, selected from polycyclic organic compounds, doped tin oxides and the hexaborides MB 6 of lanthanide and alkaline earth metals M. An independent claim is also included for preparations suitable for producing plastics parts welded with laser radiation of wavelength outside the visible range.
