Abstract: The current invention relates to a gold nickel layer comprising nitrogen inserted over a thickness equal to or greater than 0.20 ?m, characterized in that the atomic concentration of gold is at least 15% over said thickness, the atomic concentration of nickel is at least 10% over said thickness and the atomic concentration of nitrogen is at least 5% over said thickness. The invention further relates to a process for treating a gold nickel layer. The invention also relates to a connector comprising a portion of a surface which comprises such a gold nickel layer.

Abstract: The invention relates to a peripheral seal for a window pane, particularly an insulating window pane, including at least a first (5) and a second (5) glass sheet that are combined together via at least one spacer (8) that keeps same at a certain distance from one another, and between said at least two glass sheets (5), at least one inner space (4) is closed by the peripheral seal (1, 101, 102) arranged on the periphery of the glass sheets, around said inner space (4). According to the invention, the cross-section of the seal (1, 101, 102) includes a median portion and first (1011, 1021) and second (1012, 1022) end portions respectively secured to the first and second glass sheets (5). According to the invention, the cross-section of the seal (1, 101, 102) forms at least one cavity (1013, 1023) facing at least one of the side surfaces (52) of the first and second glass sheets (5).

Abstract: A conventional polymer is grafted from a plasma polymer layer provided at a substrate surface by radical polymerisation initiated from plasma induced radicals present at or in the plasma polymer, particularly radicals provided during deposition of the plasma polymer.
