Intrinsic speed characteristics of a self-propelled camphor disk under repulsive perturbations
Yuki Koyano, Jerzy Górecki, Hiroyuki Kitahata
Camphor is a well-studied material capable of generating self-propelled motion at a water surface, and the resulting dynamics can exhibit a wide range of behaviors. Here, we analyz…

Modeling the time evolution of a camphor rotor perturbed by a stationary camphor source
Jerzy Gorecki, Yuki Koyano, Hiroyuki Kitahata
A self-propelled motion resulting from the dissipation of camphor molecules on the water surface has been attracting scientific attention for more than 200 years. A generally accep…

Deformation dynamics of an oil droplet into a crescent shape during intermittent motion
Sayaka Otani, Hiroaki Ito, Tomonori Nomoto +3
A paraffin droplet containing camphor and oil red O (dye) floating on the water surface shows spontaneous motion and deformation generated by the surface tension gradient around th…
