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 …

Forward, reverse, and no motion of Marangoni surfers under confinement

S Jafari Kang, S Sur, JP Rothstein, H Masoud - Physical Review Fluids, 2020 - APS
We examine the mobility of a chemically active particle straddling the interface between a
liquid layer of finite depth and a semi-infinite layer of gas. A surface-active agent is released …

Rotational synchronization of camphor ribbons in different geometries

J Sharma, I Tiwari, D Das, P Parmananda, V Pimienta - Physical Review E, 2020 - APS
We present experiments on multiple pinned self-propelled camphor ribbons, which is a
rectangular piece of paper with camphor infused in its matrix. Experiments were performed …

Mini-generator of electrical power exploiting the Marangoni flow inspired self-propulsion

M Frenkel, A Vilk, I Legchenkova, S Shoval… - ACS …, 2019 - ACS Publications
The mini-generator of electrical energy exploiting Marangoni soluto-capillary flows is
reported. The interfacial flows are created by molecules of camphor emitted by the “camphor …

Periodic oscillations in a string of camphor infused disks

I Tiwari, P Parmananda, R Chelakkot - Soft Matter, 2020 - pubs.rsc.org
The rhythmic beating motion of autonomously motile filaments has many practical
applications. Here, we present an experimental study on a filament made of camphor …

Chimeralike states in a minimal network of active camphor ribbons

J Sharma, I Tiwari, D Das, P Parmananda - Physical Review E, 2021 - APS
A chimeralike state is the spatiotemporal pattern in an ensemble of homogeneous coupled
oscillators, described as the emergence of coexisting coherent (synchronized) and …

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 …
