Journal ArticleDOI
Interaction of foreign macroparticles in a cholesteric liquid crystal.
TL;DR: The interaction energy between spherical macroparticles immersed in a cholesteric liquid crystal due to the elastic deformation of the director field is calculated and its dependence on the particle position as well as the interparticle distance is determined.
Journal ArticleDOI
Photochemical switching between colloidal photonic crystals at the nematic-air interface.
TL;DR: A direct observation of the photochemical switching between colloidal crystals with different lattice constants in a liquid-crystal (LC) emulsion is reported and a simple theoretical description, which qualitatively agrees with experimental results, has been proposed.
Journal ArticleDOI
High-resolution bistable nematic liquid crystal device realized on orientational surface patterns
TL;DR: In this article, the four-fold symmetry of a checkerboard-like surface alignment consisted of square domains arrived at the macroscopic orientational bistability of nematic liquid crystals.
Journal ArticleDOI
Henneguya pseudorhinogobii n. sp. (Myxozoa: Myxosporea) parasitizing the gills of the freshwater goby Rhinogobius sp. OR from the Nagara River and redescription of Henneguya rhinogobii
TL;DR: Two types of infection with myxosporean parasites, which were different in cyst size, were found from the gill of Rhinogobius sp.
Journal ArticleDOI
Imaging of surface electrostatic features in phase‐separated phospholipid monolayers by scanning Maxwell stress microscopy
Takahito Inoue,Hiroshi Yokoyama +1 more
TL;DR: The scanning Maxwell stress microscope (SMM) is a versatile electric force microscope which has been developed here to image a variety of electrical features of surfaces and thin films as mentioned in this paper, imaging the surface potential distribution over phase-separated Langmuir-Blodgett monolayers of phospholipid deposited on metal substrates.
