ABSTRACT / SAŽETAK:
The Belousov-Zhabotinsky reaction is a well-known nonlinear chemical oscillator. When this reaction is conducted in a Petri dish, it exhibits both temporal nonlinearity and spatial nonlinearity showing various spatial phenomena such as standard waves, accelerated waves, wave packets, spirals, anti-spirals, Turing structures, segmented spirals, and chaos. The purpose of this study is to investigate the changes in the oscillatory dynamics of the BZ reaction both in a closed reactor and in a Petri dish upon the addition of glycerol at a constant temperature. Glycerol was chosen for its affordability, wide availability, and versatile applications. Adding glycerol shortens the oscillograms both in closed reactor system and in a Petri dish. Obtained results indicate that in the Petri dish observed patterns included dash waves and segmented spirals in both the control and experimental setups; neither Turing structures nor anti-spirals were present in both cases.
