The spiral waves in weakly excitable media are sparse: their pitch is much larger than the length of the recovery tail left by the propagating excitat

Winfree’s careful examination revealed that the tips of spiral waves could trace out complex patterns as they rotate. He coined the term ‘meandering’ for such nonperiodic spiral dynami

These structures result from a symmetry breaking instability of the basic thermodynamic state induced by nonlinearities and competition between antagonistic processes [1, 2]. Their archetype is the family of convective instabilities in hydrodynamics [3–4]. Othe

Thus multistability, oscillatory behavior and chaos have been found on all levels, from whole reactors over individual pellets to single crystal surfaces [10]. Widely different catalysts, reactions and reactor designs were used [4, 10]. With techni
