Isotopic Effect on the Kinetics of the Belousov-Zhabotinsky Reaction

In this work we present results about the deuterium isotope effect on the global kinetics of a Belousov-Zhabotinsky reaction in batch conditions. A nonlinear dependence of the Induction Period upon the percentage of deuterated reactants was found. The isotopic effect on the bromination reaction of malonic acid was evaluated.

Role of Dibromomalonic Acid in the Photosensitivity of the Ru(bpy)3-Catalyzed Belousov-Zhabotinsky Reaction

The photosensitive Belousov-Zhabotinsky (BZ) reaction catalyzed by the Ru(bpy)3 metallo-complex has been widely utilized in recent years. It has been employed in image processing,1 for pattern formation,2 in studying traveling,3 spiral,4,5 and scroll waves,6 as well as in investigations of stochastic resonance.7-9 Understanding the mechanism of photosensitivity in this reaction may facilitate t...

Combined excitatory and inhibitory coupling in a 1-D array of Belousov-Zhabotinsky droplets.

We study the dynamical behavior of one-dimensional arrays of ∼100 μm diameter aqueous droplets containing the oscillatory Belousov-Zhabotinsky (BZ) reaction, separated by narrow gaps of a fluorinated oil. In this closed system, the malonic acid concentration decreases as the reaction proceeds. Starting with a low initial malonic acid concentration, we observe a series of attractors as a functio...

Kinetic Determination of Urea in Milk Powder by Nonlinear Chemical Fingerprint Technique

To detect urea content in milk powder, a nonlinear chemical fingerprint technique was developed. In our study, Belousov-Zhabotinsky oscillatory chemical reaction (B-Z) was performed using milk powder and malonic acid as main dissipative substances. The same dosage of milk powder with or without artificially added urea was introduced to “H+ + Ce4+ + 3 BrO − + malonic acid” oscillating system, re...

Mixed Mode, Sequential and Relaxation Oscillations in the Belousov-Zhabotinsky System

The behaviour of a system composed of malonic acid (MA), KBrO3, H2SO4, and ferroin was investigated in batch experiments at various concentrations of oxygen above the chemical mixture when changing the concentration of MA. We could observe that at 10% of oxygen or more and for initial concentrations of malonic acid [MA]0 between 0.15 M and 0.6 M the system attains an equilibrium by some of mixe...
