Self-oscillating reaction

Properties of microwave photonic crystal for solution with the self-oscillatory Briggs–Rauscher reaction

In the article the description of dielectric constant of the structural elements of the chemical solution with the self-oscillating reaction Briggs–Rauscher, as measured reflection and transmission spectra of interacting with them the microwave radiation in the range of 5 to 8 GHz. It is shown that the solution may has properties of the photonic crystal with time-varying band gap.   DOI:10.18500/0869-6632-2016-24-1-31-36   Paper’s reference: Usanov D.A., Rytik A.P.

The influence of the trace substances on the nature of the briggs–rauscher oscillating reaction

The effect of hyperesthesia of characteristics of vibrations while adding the table salt (NaCl) as a trace substance into the reaction medium has been found for the Briggs–Rauscher oscillating reaction. The cycle of oscillations has already changed when the concentration of NaCl was 0.006 % of the total volume of the mixture. The so-called threshold effect involving the shutoff of self-induced vibration regime during one of the phases (dark or light phase) according to the concentration of NaCl was discovered.
