Discrimination of time-dependent inflow properties with a cooperative dynamical system
Hiroshi Ueno, Tatsuaki Tsuruyama, Bogdan Nowakowski +2
Many physical, chemical and biological systems exhibit a cooperative or sigmoidal response with respect to the input. In biochemistry, such behavior is called an allosteric effect.…
Chemo-Sensitive Running Droplet
Yutaka Sumino, Masaharu Nagayama, Hiroyuki Kitahata +4
Chemical control of the spontaneous motion of a reactive oil droplet moving on a glass substrate under an aqueous phase is reported. Experimental results show that the self-motion…
Mode Selection in the Spontaneous Motion of an Alcohol Droplet
Ken Nagai, Yutaka Sumino, Hiroyuki Kitahata +1
An alcohol (pentanol) droplet exhibits spontaneous agitation on an aqueous solution, driven by a solutal Marangoni effect. We found that the droplet's mode of motion is controlled…
Self Running Droplet: Emergence of Regular Motion from Nonequilibrium Noise
Yutaka Sumino, Nobuyuki Magome, Tsutomu Hamada +1
Spontaneous motion of an oil droplet driven by chemical nonequilibricity is reported. It is shown that the droplet undergoes regular rhythmic motion under appropriately designed bo…
