Fifth International Symposium
Engineering of Chemical Complexity
Berlin, May 25-27, 2008
Program and Organization: G. Ertl, A. S. Mikhailov
The aim of this meeting is to review current perspectives for design, manipulation and efficient control of self-organizing complex chemical systems, ranging from biotechnology and reactive nanostructures to macroscopic pattern formation in chemical reactors. Both experimental studies of such phenomena and their mathematical modeling will be discussed. Possible technological applications of self-organization phenomena shall be considered.

Putting pitting corrosion under a magnifying glass
Abstract:
Stainless steels are designed to be corrosion-resistant. Nevertheless they can undergo localized pitting corrosion, which may rapidly lead to their failure, with the possibility of catastrophic events as a result. To study the initial steps of metastable pit formation in situ and in real time we adapted our ellipso-microscope for surface imaging (EMSI) and a high resolution, contrast-enhanced optical microscope to the electrolyte - stainless steel interface. Utilizing these methods we have been able to explain the sudden corrosion onset by an explosive autocatalytic growth in the number of metastable pits [1].
Recently by applying those different imaging methods simultaneously the correlation between oxide film weakening and the nucleation of individual pits was examined. The existence of front propagation as a component of the transition to pitting corrosion shows that characteristics of this process are consistent with the behavior of stochastic reaction-diffusion systems [2].
We are currently working to implement digital in-line holography as a third imaging tool to achieve three-dimensional information of the actual pitting events.
