Aims

The students understand the central role of interfaces for environmental processes such as sorption and transport of environmental contaminants, bioavailability and toxicity. They understand the intense interactions between physics, chemistry and biology. The students gain experience in the analysis of interfacial processes and are competent for independent interdisciplinary process-oriented experiments.
