Direction control of chemical wave propagation in self-oscillating gel array
Article Abstract:
A chemomechanical actuator using a reaction-diffusion wave across gap junction is constructed for studying a novel microconveyer by micropatterned self-oscillating gel array. Numerical analysis based on the Keener-Tyson model is used for understanding the mechanism of unidirectional propagation in triangle and pentagonal gel arrays and the swelling and deswelling changes of the gels have followed the unidirectional propagation of the chemical wave.

Dependence of turbidity oscillations of self-oscillating polymers on the selective recognition of the crown ether receptors contained in the polymer chain
Article Abstract:
The turbidity oscillations of self-oscillating polymers in the Belousov-Zhabotinsky (BZ) reaction system depending on the crown ether receptors contained in the polymer network are analyzed. The turbidity oscillation patterns of the redox changes obtained by these solution systems have looked much alike despite the differences in the polymer chain by crown ether receptors and cations of bromate used for the BZ reaction.

Pressure-induced reduction of shielding for improving sonochemical activity
Article Abstract:
The oxidation of potassium iodide, bubble cloud visualization studies and sound attenuation measurements are applied to determine the influence of hydrostatic pressure on chemical reactions induced by 20 kHz ultrasound. It is demonstrated that a rise in hydrostatic pressure leads in a rise in yield for the oxidation of potassium iodide in aqueous solution and the sound field is more intense for higher pressures.
