A halogen incandescent lamp may include a bulb, in which a light-emitting element and a fill with a halogen-containing additive is accommodated, the halogen containing F, wherein a fluorine-resistant layer which is passive at suitable temperatures is accommodated in the interior of the bulb and completely covers the inner wall.
摘要:
A catalyst for hydrogen generation from an alkaline aqueous solution of hydrogen containing salts comprising a silicon-based ceramic surface covered with a mixture of metals known as transition metals and noble metals. The silicon-based ceramic surface may be self-supporting or may be deposited as a thin film on a carbonaceous substrate. The carbonaceous surface may be self-supporting or be in the form of a film that is supported on a substrate of a fourth material, where the fourth material has the function of providing physical support to the substrate. The said carbonaceous substrate can be made from a solid material or from a porous structure, of which carbon nanotube paper, also known as Bucky paper, is one example.
