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.
Shnoll gave the project to a graduate student, Anatol Zhabotinsky, who investigated the reaction in detail and succeeded in publishing his results. [6] The reaction now bears the names of both Belousov and Zhabotinsky. [7] Belousov was posthumously awarded the Lenin Prize in 1980 for his work on the BZ reaction. [7]
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 ...
Belousov's ability to get things done - having raised around 300 billion roubles ($3 billion) with a tax on corporate windfall profits - is likely to have impressed President Vladimir Putin.
The active ingredient is the [Fe(o-phen) 3] 2+ ion, which is a chromophore that can be oxidized to the ferric derivative [Fe(o-phen) 3] 3+. The potential for this redox change is +1.06 volts in 1 M H 2 SO 4. It is a popular redox indicator for visualizing oscillatory Belousov–Zhabotinsky reactions.
