A stirred BZ reaction mixture showing changes in color over time. The discovery of the phenomenon is credited to Boris Belousov.In 1951, while trying to find the non-organic analog to the Krebs cycle, he noted that in a mix of potassium bromate, cerium(IV) sulfate, malonic acid, and citric acid in dilute sulfuric acid, the ratio of concentration of the cerium(IV) and cerium(III) ions ...
A Belousov–Zhabotinsky reaction is one of several oscillating chemical systems, whose common element is the inclusion of bromine and an acid. An essential aspect of the BZ reaction is its so-called "excitability"—under the influence of stimuli, patterns develop in what would otherwise be a perfectly quiescent medium.
A chemical computer, also called a reaction-diffusion computer, Belousov–Zhabotinsky (BZ) computer, or gooware computer, is an unconventional computer based on a semi-solid chemical "soup" where data are represented by varying concentrations of chemicals. [1] The computations are performed by naturally occurring chemical reactions.
The Oregonator is a theoretical model for a type of autocatalytic reaction. The Oregonator is the simplest realistic model of the chemical dynamics of the oscillatory Belousov–Zhabotinsky reaction. [1] It was created by Richard Field and Richard M. Noyes at the University of Oregon. [2] It is a portmanteau of Oregon and oscillator.
The Belousov family had strong anti-Tsarist sympathies and, after the Russian Revolution of 1905, they were arrested and later forced to leave the country. [2] They settled in Switzerland, where Boris studied chemistry in Zürich. Returning to Russia at the beginning of World War I, [3] Belousov tried to join the army, but was denied for health ...

MOSCOW (Reuters) -Russia's main task is to achieve victory on the battlefield in Ukraine with the minimal loss of troops, incoming defence minister Andrei Belousov said on Tuesday. Belousov, an ...
Noise-induced order is a mathematical phenomenon appearing in the Matsumoto-Tsuda [1] model of the Belosov-Zhabotinski reaction.. In this model, adding noise to the system causes a transition from a "chaotic" behaviour to a more "ordered" behaviour; this article was a seminal paper in the area and generated a big number of citations [1] and gave birth to a line of research in applied ...
