Swimming droplet in 1D geometries, an active Bretherton problem
Charlotte de Blois, Vincent Bertin, Saori Suda +3
We investigate experimentally the behavior of self-propelled water-in-oil droplets, confined in capillaries of different square and circular cross-sections. The droplet's activity…
Geometry-driven collective ordering of bacterial vortices
Kazusa Beppu, Ziane Izri, Jun Gohya +3
Controlling the phases of matter is a challenge that spans from condensed materials to biological systems. Here, by imposing a geometric boundary condition, we study controlled col…
Wrinkling of a spherical lipid interface induced by actomyosin cortex
Hiroaki Ito, Yukinori Nishigami, Seiji Sonobe +1
Actomyosin actively generates contractile forces that provide the plasma membrane with the deformation stresses essential to carry out biological processes. Although the contractil…
Dynamics of microdroplets over the surface of hot water
Takahiro Umeki, Masahiko Ohata, Hiizu Nakanishi +1
When drinking a cup of coffee under the morning sunshine, you may notice white membranes of steam floating on the surface of the hot water. They stay notably close to the surface a…
Rotational motion of a droplet induced by interfacial tension
Ken H. Nagai, Fumi Takabatake, Yutaka Sumino +3
Spontaneous rotation of a droplet induced by the Marangoni flow is analyzed in a two-dimensional system. The droplet with the small particle which supplies a surfactant at the inte…
Direct measurement of single soft lipid nano-tubes: nano-scale information extracted in non-invasive manner
Akihisa Yamamoto, Masatoshi Ichikawa
We investigated the dynamics of single soft nano-tubes of phospholipids to extract nano-scale information such as size of tube, which are several tens to hundreds of nano-meters th…
Entrapping a polymer chain in a light well under a good solvent condition
Masatoshi Ichikawa, Kenichi Yoshikawa, Yukiko Matsuzawa
During the last decade, the laser trapping technique has been actively applied to elucidate the property of macromolecules, DNA, RNA, cytoskeleton fibres, etc. Due to the inherent…
