The fuel mixture is injected into the internal combustion engine or the nozzle. A pressure is in a range of from 100 to 4,000 bar.

Abstract: A method for preparation of a molecular recognition element comprising the steps of binding a template to a surface of a carrier material, providing a recognition material to the surface of the carrier material, initiating polymerization of the recognition material on the surface of the carrier material, stopping the polymerization of the recognition material on the surface of the carrier material, and releasing the template from the surface of the carrier material and the polymerized recognition material. The method is characterized as an aim size of individual imprints is predefined, and the polymerization of the recognition material on the surface of the carrier material is stopped when a size of individual imprints of the polymerized recognition material essentially equals the predefined aim size. This method is readily applicable for preparation of a molecular recognition element useful as a drug, catalyst, competitive affinity ligand inhibitor, competitor, agonist, antagonist or diagnostic agent.

Abstract: A head-rest of a vehicle seat with a deformable central supporting body which forms an impact zone for the head of a vehicle occupant and into which the kinetic energy of the head in the event of an accident is admitted. On both sides of the impact zone the central supporting bodies are joined by lateral supporting surfaces which are extendable out of the plane of the head-rest in the direction of travel in order to laterally support the head. In order to avoid or at least to reduce the risk of a cervical-spine whiplash injury, it is proposed according to the invention that the head-rest comprises a device for absorbing the energy admitted into the central supporting body and for outputting the absorbed energy in order to activate lateral supporting surfaces.

Abstract: The present invention relates to an improved process for producing highly ordered nanopillar or nanohole structures, in particular on large areas, which can be used as masters in NIL, hot embossing or injection molding processes. The process involves decorating a surface with an ordered array of metal nanoparticles produced by means of a micellar block- copolymer nano-lithography process; etching the primary substrate to a depth of 50 to 500 nm, where the nanoparticles act as a mask and an ordered array of nanopillars or nanocones corresponding to the positions of the nanoparticles is thus produced; using the nanostructured master or stamp in a structuring processes. Also the finished nanostructured substrate surface can be used as a sacrificial master which is coated with a continuous metal layer and the master is then etched away to leave a metal stamp having an ordered array of nanoholes which is a negative of the original array of nanopillars or nanocones.
