The present invention describes the highly advantageous properties of a mixture of thiol-perfluoropolyether (PFPE) molecules with perfluorinated bisphosphonic (PF-BP) compounds. This mixture makes it possible in effect to obtain a lipophobic behavior (also referred to as epilame effect) with common watch-making lubricants on all the materials tested, including metals, inter alia gold and alloys thereof, ceramics and semiconductors, and gives the surface treated a good resistance to ageing and to cleaning products.

The invention relates to a process for producing a component having improved elongation at break properties, in which a component is firstly produced, preferably in a hot forming or press curing process, and the component is heat treated after hot forming and/or press curing, where the heat treatment temperature T and the heat treatment time t essentially satisfy the numerical relationship T900.Math..sub.t.sup.0.087, where the heat treatment temperature T is in C. and the heat treatment time t is in seconds. The invention also relates to a component, in particular an automobile body component or the chassis of a motor vehicle, which has been produced by such a process. The invention further relates to the use of such a component as part of an automobile body or a chassis of a motor vehicle.

A process for surface activation or depassivation of an article, in particular an alloy, by immersion of the alloy in an aqueous acid solution. The surface activation methods of the present invention can be performed during a relatively short period of time and achieve reductions in production costs and provide environmental friendliness as compared to prior art processes. In a further embodiment, after surface activation, the article is immersed in a second liquid that prevents re-formation of a passivating oxide layer on the surface of the article. In a further embodiment the surface-activated alloys are subjected to surface engineering by a process that infuses carbon or nitrogen through the surface at a temperature sufficiently low to suppress precipitation of carbides or nitrides.

Deposition of Pt nanoparticles on UiO metal organic frameworks via solvothermal reduction is achieved by reducing Pt acetylacetonate (Pt(acac).sub.2) in a UiO-66 and N,N-dimethylformamide (DMF) mixture at, for example, 130 C. for 18 hrs. Modification of reaction temperature and time can control the size of the Pt nanoparticles.

A process for positive microcontact printing, including inking a patterned mold with a thiol; contacting the mold with a metal surface of a substrate; backfilling the metal surface with a solution containing an aromatic amine to form a backfilling layer; etching the metal surface of the substrate; and rinsing the substrate to remove the backfilling layer.
