| Research Abstract |
Hollow asymmetirical silica dumbbells with a movable inner core were prepared as a model to show the control over the position of inner cores by external fields. The movability of inner cores were shown by observations in which silica spheres confined in spherical silica shell could be randomly moved by Brownian motion. These results suggest that the hollow asymmetirical dumbbells have a potential to be used as switching materials with an external field.
