GRK 689: Reactivity in the Surface Region

研究训练组的目的是调查真实表面的行为和非常不同材料的表面区域与相关反应物的相互作用。由于埃森大学所涉及的工作组的特殊星座，对表面过程的非凡广泛处理将成为可能。从能量或粒子与表面的相互作用引起的基本反应，通过涂层问题来改进材料，建筑材料在恶劣环境中的内表面的相互作用，直到众所周知的医疗植入物和生物系统的相互作用。在所有这些表面上截然不同的领域中，各自材料的本质行为是在其表面与相应环境的相互作用中看到的。这对于医疗植入物来说是非常明显的，它的寿命不再取决于它们的机械稳定性，而是取决于它们表面的生物相容性。

The research training group is aimed at the investigation of the behaviour of real surfaces and of surface regions of very different materials with respect to their interactions with relevant reactants. Owing to the special constellation of the involved working groups at the University of Essen, an extraordinary broad treatment of surface processes will become possible. Those are reaching from elementary reactions, caused by interactions of energy or particles with surfaces, via coating problems to refine materials, the interaction of inner surfaces of building materials in aggressive environments, up to the well known interaction of medical implants and biological systems. In all of these only apparently very different areas the essential of the behaviour of the respective material is to be seen in the interaction of its surface with the corresponding environment. This becomes very obvious for medical implants, the lifetime of which is no longer dependent on their mechanical stability, but on the biocompatibility of their surfaces.
