GRK 689: Reactivity in the Surface Region

研究培训小组的目的是调查真实的表面和非常不同的材料的表面区域与相关反应物相互作用的行为。由于埃森大学的工作组的特殊布局，表面过程的异常广泛的处理将成为可能。这些是从基本反应，由能量或粒子与表面的相互作用引起的，通过涂层问题来精炼材料，建筑材料的内表面在侵蚀性环境中的相互作用，直到众所周知的医疗植入物和生物系统的相互作用。在所有这些表面上只有非常不同的区域中，相应材料行为的本质可以从其表面与相应环境的相互作用中看出。这对于医疗植入物来说变得非常明显，其寿命不再取决于其机械稳定性，而是取决于其表面的生物相容性。

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.
