| Outline of Final Research Achievements |
When temperature gradient is applied to the droplets formed by cholesteric liquid crystals (Ch droplets), a rotational motion is induced. We experimentally analyzed the physical mechanism of this phenomenon. As a result, it was found that the rotation was driven effectively when the Ch droplet has the helical structure along the temperature gradient, and that a convective flow was induced in the droplet when the gradient was applied. These results suggest that the rotational motion is induced when the material flow goes through the helical structure of the Ch droplets, just like a propeller.
