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.
Boris Pavlovich Belousov (Russian: Бори́с Па́влович Белоу́сов; 19 February 1893 – 12 June 1970) was a Soviet chemist and biophysicist who discovered the Belousov–Zhabotinsky reaction (BZ reaction) in the early 1950s. His work initiated the field of modern nonlinear chemical dynamics. [1]
Russian President Vladimir Putin has proposed a surprise new defence minister, nominating civilian Andrei Belousov, a former deputy prime minister who specialises in economics, for the job more ...
The best-known example is the clock reaction, the Belousov–Zhabotinsky reaction (BZ reaction). It can be created with a mixture of potassium bromate (KBrO 3 ), malonic acid (CH 2 (COOH) 2 ), and manganese sulfate (MnSO 4 ) prepared in a heated solution of sulfuric acid (H 2 SO 4 ).
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.
