Objective
Far from thermodynamic equilibrium, temporal or spatial structures can spontaneously emerge in systems involving nonlinear cooperative processes. Chemical "dissipative structures" are one of the main topics of this nonlinear science. Since the initial discovery , in 1990, of the stationary concentration patterns predicted by the mathematician Alan Turing in 1952, there has been much experimental progress in the field of chemical patterns. However, this field is still in its enfancy. Many theoretically predicted spatial instabilities have not yet been clearly identified and only two kinetically different reactions have produced stationary patterns in such reactors, yet. During our stay , the research work should develop in two directions: i) the search for new types of chemical patterns in different bistable and oscillatory variants of the chlorite-iodide reactions. These systems will be used a prototypic systems for the elaboration of effective systematic methods to produce and control patterns in different other reactions. The method will then be applied to pH-auto activated nonlinear reactions. ii) the discovery of chemo-mechanical instabilities leading to stationary pulsating shape changes in deformable soft porous medium, used as support for the nonlinear reaction. In this part, we shall make use of pH-auto activated oscillatory or bistable reactions operated within polyelectrolyte gels. Beside more theoretical considerations, the latter research may lead to results of potential relevance in morphogenesis (joe. the birth and growth of forms in living systems ).Interest in nonlinear chemical dynamics has recently focused on studying spatial phenomena in open systems. One of the most important benefits of the requested training for the applicant is to acquire the theory and practice of chemical pattern formation in open spatial reactors. The host group is one of the most experimented in this field. In our laboratory in Budapest, our group does not have the experience and instruments for this type of experiments. From the chemical point of view , I shall learn about new oscillatory systems and use my knowledge of the chemical oscillatory reaction kinetics to develop a deeper understanding of their mechanism which would be very useful for the host research program. Further more, I shall also participate to the elaboration of a new field, the chemo-mechanical structures which the host group is recently trying to develop. This field is of very high potential interest in biology and intelligent material science.
