Microfluidic Systems for the Belousov-Zhabotinsky Reaction
We describe an experimental methodology for the study of chemical self-organization in micropatterned reaction systems. Our approach is based on office-printer-assisted soft lithography and allows the fabrication of centimeter-scale devices with reactor units as small as 50 μm. The devices are made from the elastomeric material poly(dimethylsiloxane) and are filled with a modified Belousov-Zhab...
متن کاملIntermittent behaviour in the Belousov-Zhabotinsky reaction
2014 One of the possible routes to turbulence is the intermittent transition. Below the onset of turbulence regular oscillations exist, and above the onset seemingly regular oscillations are interrupted randomly by large amplitude bursts. This behaviour shows up in the Belousov-Zhabotinsky reaction. Moreover an analysis of the measurements indicates that a so-called « type 1 » transition takes ...

متن کاملChaos in the Belousov-Zhabotinsky Reaction
In this project, we investigate two different models of the Belousov-Zhabotinsky Reaction, the Oregonator (1973) and a model found in a 1992 paper by Györgyi and Field. We discuss the original literature and then numerically investigate both models. We find the the Oregonator is not chaotic, and that the Györgyi-Field model is for certain values of a variable parameter. For each model, we solve...
متن کاملExperimental Survey of Spiral Dynamics in the Belousov-Zhabotinsky Reaction
— We present a systematic study of spiral waves in the Belousov-Zhabotinsky reaction in a spatial open reactor, where the concentrations of sulfuric acid, sodium bromate, and malonic acid are varied. Within this parameter space, three kinds of instabilities arise: two of them, which we identify as the retracting wavefront and convective instabilities, lead to the destruction of the spiral patte...
