  • Device and method for the production of singlet oxygen
    Publication number: 20040076559
    Abstract: A device for producing singlet oxygen and having a light source and a transparent medium is described. The transparent medium has a first surface and second surface, the first surface facing the light source and a region which contains a photosensitizer are disposed on the second surface. The transparent medium is completely closed against a surrounding medium.

  • Glazing element, in particular for facing building facades
    Patent number: 5864994
    Abstract: A glazing element, in particular, for facing building facades, having two nes enclosing a gaseous atmospheric intermediate space and having a predetermined layer on at least one pane surface facing the intermediate space. The glazing element is distinguished by the fact that the predetermined layer has a reactive layer applied on one pane and a catalytic layer applied on the reactive layer. The catalytic layer, depending on the composition of the gas atmosphere contained between the panes, activates in the reactive layer. The reaction changes the optical and/or electrical properties of the reactive layer, and varies the composition of the gas atmosphere in the intermediate space, thereby making the electrical and/or optical properties of the reactive layer variable.
