| Outline of Final Research Achievements |
Spatiotemporally controlled and self-powered fluidic flows under nonequilibrium conditions are ubiquitous in nature, ranging from supernovae in space to “coffee-rings” on our tables. A physicochemical understanding on these fluidic flows helps us to learn the origin of the robustness, exquisiteness, and simplicity of nature. Furthermore, the spatiotemporal control of fluidic flow offers self-powered pumps for installation in next-generation smart miniature devices. In this project, a one-directional flow induced by chemical wave propagation was investigated to understand the origin of its dynamic flow and its possibility toward mass-transport in microfluidics. Our findings offer unique hydrodynamic effect coupling with the chemical wave propagation, where it would be a characteristic feature that the hydrodynamic effect was not caused at the reaction front but at the initiation point.
