Dynamics and mechanism of liquid film collapse in a foam

N Yanagisawa, M Tani, R Kurita - Soft Matter, 2021 - pubs.rsc.org
Foams have unique properties that distinguish them from ordinary liquids and gases, and
are ubiquitously observed in nature, both in biological systems and industrial products …

Universal relaxation dynamics of sphere packings below jamming

A Ikeda, T Kawasaki, L Berthier, K Saitoh, T Hatano - Physical review letters, 2020 - APS
We show that non-Brownian suspensions of repulsive spheres below jamming display a
slow relaxational dynamics with a characteristic timescale that diverges at jamming. This …

[HTML][HTML] Scraping of foam on a substrate

M Endo, M Tani, R Kurita - Journal of Colloid and Interface Science, 2023 - Elsevier
Hypothesis: Foam is not only an industrially important form of matter, but also one of soft
jammed system such as colloidal suspensions and emulsion suspensions. Since foams are …

Cross over to collective rearrangements near the dry-wet transition in two-dimensional foams

N Yanagisawa, R Kurita - Scientific Reports, 2023 - nature.com
Liquid foams respond plastically to external perturbations over some critical magnitude. This
rearrangement process is directly related to the mechanical properties of the foams, playing …

Size distribution dependence of collective relaxation dynamics in a two-dimensional wet foam

N Yanagisawa, R Kurita - Scientific Reports, 2021 - nature.com
Foams can be ubiquitously observed in nature and in industrial products. Despite the
relevance of their properties to deformation, fluidity, and collapse, all of which are essential …

In-situ observation of collective bubble collapse dynamics in a quasi-two-dimensional foam

N Yanagisawa, R Kurita - Scientific Reports, 2019 - nature.com
The stability of foams is an important subject not only for fundamental science, but for
applications in daily life. The most destructive phenomenon underpinning foam collapse is a …

Nanobubble-assisted nanopatterning reveals the existence of liquid quasi-two-dimensional foams pinned to a water-immersed surface

H Tarábková, P Janda - Langmuir, 2020 - ACS Publications
This paper reports on our observation of a quasi-two-dimensional (quasi-2D) liquid
nanofoam spontaneously appearing on a submersed solid surface. Unlike common liquid …

Spreading of foam on a substrate

M Endo, M Tani, R Kurita - arXiv preprint arXiv:2302.12390, 2023 - arxiv.org
Foam is an industrially important form of matter, commonly deployed to clean objects and
even our own skin, thanks to its ability to absorb oil and particles into its interior. To clean a …
