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.

Modelling cell motility: motion from chemistry
Abstract:
We present a simple and generic theoretical description of
actin-based motility, where polymerization of filaments maintains propulsion. The dynamics is driven by polymerization at the filaments free ends, crosslinking of the actin network, attachment and detachment of filaments to the obstacle interface and entropic forces. We show that spontaneous oscillations in the velocity emerge due to a push-pull mechanism in a broad range of parameter values, and compare our findings with experiments.
