Droplets of cholesteric liquid crystals rotate their helical structure when subjected to a thermal gradient perpendicular axes. Concerning the interpretation dynamics, there has been an argument whether textural rotation indicates rigid-body droplets or pure director rotation. To clarify this, we dispersed micron-size particles in cholesteric-isotropic coexisting sample and traced motion, found that adhering onto droplet rotated together with helix phase. This observation provided clear...
We succeeded in driving the unidirectional rigid-body rotation of cholesteric (Ch) double-twist cylinder (DTC) droplets under a heat flux along cylindrical symmetry axis.
This paper describes the application of a loop type inductively coupled thermal plasmas (loop-ICTPs) to high-speed oxidation processing. We earlier developed unique loop-ICTP for large-area plasma materials In this oxidation, part Ar/O <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> was formed directly lying in longitudinal direction on surface Si substrate located downstream torch. Oxygen supplied from sides substrate. The uniformity...
We fabricated aggregates of cholesteric cylinders coexisting with the isotropic phase and investigated their dynamics under a temperature gradient. Each constituent cylinder possessed double-twist (DT) structure, when heat flux was applied, whole rotated as rigid-body without changing DT orientation. The angular velocity proportional to rotational direction determined by molecular chirality direction. result suggests that rotation driven thermomechanical cross-correlation in chiral LCs. also...
Abstract In this work, the fundamentals of planar-type Ar inductively coupled thermal plasmas (ICTPs) with oxygen molecular gas on a substrate have been studied. Previously, aiming at large-area material processing, we developed ICTP torch rectangular quartz vessel instead conventional cylindrical tube. For adoption such to it is necessary sustain gases stably and uniformly. To determine uniformity formed substrate, spectroscopic observation was carried out 3 mm above substrate. Results...
We show that cholesteric (Ch) liquid crystal droplets with cylindrically symmetric orientation dispersing in an isotropic (Iso) phase exhibited unidirectional rotation under a heat flux along the symmetry axis. By introducing colloidal particle adhesive to Ch droplet surface, we traced translational motion of colloids and found rotated unidirectionally around center each droplet. The director configuration was not distorted either spatially or temporally, while constantly. results suggest...
