Identification of the best medium for experiments on chemical computation with Belousov–Zhabotinsky reaction and ferroin-loaded Dowex beads

Abstract Our study is focused on identification of the best medium for future experiments information processing with Belousov–Zhabotinsky reaction proceeding in Dowex beads immobilized catalyst inside. The optimum should be characterized by long and stable nonlinear behavior, mechanical stability allow control electric potential. We considered different types ion-exchange resins, bead distributions various initial concentrations substrates: malonic acid 1,4-cyclohexanedione. potential platinum electrodes, stabilized a potentiostat used to evolution. A negative generates activator species HBrO 2 working electrode according reaction: BrO 3 ? + 2e 3H ? H O, while positive attracts inhibitor Br proximity it. oscillation amplitude period systems ferroin loaded 50W-X2 50W-X8 during exceeding 16 h. It has been observed, that above mentioned resins generate smaller number CO bubbles close than 50W-X4, which makes more suitable applications chemical computing. report stability, frequency, merging annihilation travelling waves lattice (mesh size 50–100) over 19 h equimolar solution This system looks as promising candidate computing devices can operate day.
