Perturbation studies of excitable media
… 4 and 7, the ferrocyanide-iodate-sulfite (FIS) reaction, which exhibits pH oscillations between 4 and 7.5 in a continuously stirred tank reactor (CSTR), is a good candidate for studies of oscillatory gel systems.;This work also focused on two dynamical phenomena in the ruthenium catalyzed …

Nonlinear oscillation and control in the BZ chemical reaction.
… oscillation of the Belousov-Zhabotinsky(BZ) reaction in a closed isothermal chemical system. The reaction zone can be divided into two zones, oscillation zone and transition zone, where the oscillation time and the transition time and the number of the complete oscillations are estimated. …

Anomalous Wave Dispersion in the Cyclohexanedione-Bromate Chemical Oscillator
… variant of the Belousov-Zhabotinsky (CHD-BZ) reaction. The phenomena of anomalous velocity dispersion (in which following waves may catch up to, rather than fall behind an initial excitation wave), wave-stacking, and backfiring have been successfully reproduced numerically as resulting …

Magnetic resonance studies of chemical reactions in microemulsions
The Belousov-Zhabotinsky (BZ) reaction is the preeminent oscillating chemical reaction for the study of pattern formation in reaction-diffusion systems. The dispersal of the reaction in a water-in-oil AOT microemulsion (BZ-AOT reaction) gives rise to an extended range of patterns, including dash …

Visualisation of chemistry in flow
… the pattern-producing Belousov- Zhabotinsky (BZ) reaction under flow using a combination of optical and magnetic resonance (MRI) imaging techniques. The coupling between reaction-diffusion and advection was studied in three distinct systems. Stationary flow-distributed oscillation (FDO) …

Chemomechanics of self-oscillating gels
… a unique class of polymeric materials known as BZ gels, that are capable of undergoing the Belousov- Zhabotinsky (BZ) self-oscillating reaction. When submerged in stagnant solution containing chemical reactants, and in the absence of continuously applied external perturbation, the BZ gels …

Chemische Wellen und Fronten in nichtlinearen Reaktions-Diffusions-Systemen
… in der Belousov-Zhabotinsky-Reaktion (BZ-Reaktion). Ein weiterer Teilabschnitt behandelt die Wechselwirkung zwischen Polymersystemen und nichtlinearen chemischen Reaktionen. In den untersuchten, räumlich ausgedehnten Systemen spielt die Kopplung nichtlinearer chemischer Reaktionen an …
