SW Song, S Lee, JK Choe, AC Lee, K Shin… - Nature …, 2023 - nature.com
Pen-drawing is an intuitive, convenient, and creative fabrication method for delivering
emergent and adaptive design to real devices. To demonstrate the application of pen …

A curious formulation robot enables the discovery of a novel protocell behavior

J Grizou, LJ Points, A Sharma, L Cronin - Science advances, 2020 - science.org
We describe a chemical robotic assistant equipped with a curiosity algorithm (CA) that can
efficiently explore the states a complex chemical system can exhibit. The CA-robot is …

Capillarity-driven migration of small objects: A critical review

J Liu, S Li - The European Physical Journal E, 2019 - Springer
The phenomena on the capillarity-driven migration of small objects are full of interest for
both scientific and engineering communities, and a critical review is thereby presented. The …

Dynamic ordering in a swarm of floating droplets driven by solutal Marangoni effect

S Tanaka, S Nakata, T Kano - Journal of the Physical Society of …, 2017 - journals.jps.jp
We review our recent results on a simple droplet system consisting of droplets of a mixture of
two liquids. Although the system is composed of simple chemicals, it is capable of exhibiting …

Relationship between the size of a camphor-driven rotor and its angular velocity

Y Koyano, M Gryciuk, P Skrobanska, M Malecki… - Physical Review E, 2017 - APS
We consider a rotor made of two camphor disks glued below the ends of a plastic stripe. The
disks are floating on a water surface and the plastic stripe does not touch the surface. The …

Dancing performance of organic droplets in aqueous surfactant solutions

J Čejková, K Schwarzenberger, K Eckert… - Colloids and Surfaces A …, 2019 - Elsevier
Droplet systems remain the subject of a constant fascination in science and technology.
Here we focus on organic droplets floating on the surface of aqueous surfactant solutions …

Rotational motion of a camphor disk in a circular region

Y Koyano, NJ Suematsu, H Kitahata - Physical Review E, 2019 - APS
In a two-dimensional axisymmetric system, the system symmetry allows rotational or
oscillatory motion as stable stationary motion for a symmetric self-propelled particle. In the …

Imperfect bifurcation in the rotation of a propeller-shaped camphor rotor

Y Koyano, H Kitahata - Physical Review E, 2021 - APS
We investigated the bifurcation structure on the self-propelled motion of a camphor rotor at a
water surface. The center of the camphor rotor was fixed by the axis, and it showed rotational …
