The article is dedicated to the outstanding scientist, doctor, teacher, public figure, corresponding member of Russian Academy Sciences, professor, doctor medical sciences Belousov Yuri, who would have turned 80 on September 23, 2022. presented materials make it possible recall main milestones in biography this remarkable person. based collected by relatives, friends, colleagues and students Yu...

Elementary model of intracellular (or intra-organellar) pattern formation: Belousov – Zhabotinsky reaction in a Petri dish. The Belousov – Zhabotinsky reaction (Belousov 1958) was devised as a primitive model of citric acid cycle. To the surprise of the authors, it brought about the phenomenon of chemical clock (in mixed systems) or spontaneous pattern formation (in still compartments). We use ...

In this article, we present a modified strategy that combines the residual power series method with Laplace transformation and novel iterative technique for generating solution to fractional nonlinear Belousov–Zhabotinsky (BZ) system. The proposed techniques use Laurent in their development. new procedures’ advantages include accuracy speed obtaining exact/approximate solutions. suggested appro...

We present experiments on the synchronization of a dynamical, chemical process in an extended, flowing, fluid system. The oscillatory Belousov-Zhabotinsky chemical reaction is the process studied, and the flow is an annular chain of counterrotating vortices. Azimuthal motion of the vortices is controlled externally, enabling us to vary the type of transport. We find that oscillations of the Bel...

For many years the Belousov–Zhabotinsky reaction has been used to explore the large variety of dynamical behavior of excitation waves. The understanding of chemical waves can be applied to other physical and biological systems. Most theoretical and experimental work has been done in planar media, whereas for nonplanar systems there exist many theoretical but only very few experimental studies. ...
