Outline of Final Research Achievements

Experimental studies on the emergence of autonomous motion of non-biological systems under nonequilibrium stationary conditions. 1) Emergence of spatial ordering of droplets was studied. 2) Autonomous motion of droplet under laser irradiation was studied. 3) Spontaneous back-and-go rhythmic motion of aqueous droplet under DC electronic field was studied.
