Growth of self-integrated atomic quantum wires and junctions of a Mott semiconductor
Tomoya Asaba, Lang Peng, Takahiro Ono +13
Continued advances in quantum technologies rely on producing nanometer-scale wires. Although several state-of-the-art nanolithographic technologies and bottom-up synthesis processe…
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…
Oscillation and collective conveyor of water-in-oil droplets by microfluidic bolus flow
Takuya Ohmura, Masatoshi Ichikawa, Ken-ichiro Kamei +1
Microfluidic techniques have been extensively developed to realize micro-total analysis systems in a small chip. For microanalysis, electro-magnetic forces have generally been util…
Molecular behavior of DNA in a cell-sized compartment coated by lipids
T. Hamada, R. Fujimoto, S. F. Shimobayashi +2
The behavior of long DNA molecules in a cell-sized confined space was investigated. We prepared water-in-oil droplets covered by phospholipids, which mimic the inner space of a cel…
Phase-separation transitions in asymmetric lipid bilayers
Shunsuke F. Shimobayashi, Masatoshi Ichikawa, Takashi Taniguchi
Morphological transitions of phase separation associated with the asymmetry of lipid composition were investigated using micrometer-sized vesicles of lipid bilayers made from a lip…
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…
Mode bifurcation on the rythmic motion of a micro-droplet under stationary DC electric field
Tomo Kurimura, Masahiro Takinoue, Masatoshi Ichikawa +1
Accompanied by the development of microfabrication techniques, such as MEMS and micro-TAS, there has been increasing interests on the methodology to generate a desired motion on a…
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…
