Abstract: Logic gates based on chemical wave propagation in geometrically constrained excitable media are demonstrated in a Belousov−Zhabotinsky membrane system. The catalyst of the reaction is printed in specific predetermined patterns with geometries designed to provide various logic operations. Computational studies of the serial coupling of elements to form multicomponent gates and general chemical wave circuitry are presented.

TL;DR: It was observed that the results from the CA-based Oregonator are in good agreement with both modelled and laboratory experiments, and the main advantage can be summarized as the acceleration achieved in current implementations (serial computers), but also towards potential future implementations in massively parallel computational systems that have been proved to be good substrates for accelerating the implemented CA models.

On the response of simple reactors to regular trains of pulses
TL;DR: In this paper, the authors consider a few examples of such reactors and study their response to a chemical input of high frequency, and demonstrate that the response of a signal processing device may depend on the input frequency.

Hierarchical network of pulse coupled chemical oscillators with adaptive behavior: Chemical neurocomputer.
TL;DR: This network of pulse coupled oscillators with time delays is considered theoretically a chemical neurocomputer, since chemical BZ reaction occurs in each micro-oscillator, while pulse connectivity of these cells is inspired by the brain.
