Comparative Study of Anchoring Strengths for Photo- and Rubbing-Aligned Liquid Crystals on Photoisomerizable Polyimide Alignment Films

TL;DR: In this article, high-electric-field technique was used to measure the out-of-plane (polar) anchoring strength at the interface between a nematic liquid crystal, pentylcyanobiphenyl (5CB), and a photosensitive polyimide (PI) alignment layer possessing an azo group in the main chain.

Method of producing three-dimensional structure and fine three-dimensional structure

TL;DR: In this article, a method of producing a 3D structure is described, which consists of arranging a substrate close to a tip of a needle-shaped fluid-ejection body having a fine diameter supplied with a solution, ejecting a fluid droplet having an ultra-fine diameter toward a surface of the substrate by applying a voltage having a prescribed waveform to the needle-shape fluid-evading body, making the droplet fly and land on the substrate, and solidifying the droplets after the fluid droplets is landed on the surface, wherein the structure is grown
Journal ArticleDOI

Effect of introducing thioether linkages on the molecular organization of chiral twin liquid crystals

TL;DR: In this paper, the effect of substituting oxygen for sulphur on the liquid crystalline properties of chiral twin compounds was investigated, and different effects of introducing the thioether linkage were observed between twin and monomeric systems.
Journal ArticleDOI

Modes of transmission of Glugea plecoglossi (Microspora) via the skin and digestive tract in an experimental infection model using rainbow trout, Oncorhynchus mykiss (Walbaum).

TL;DR: This study indicates that skin wounds and the gut epithelium can be portals of entry of G. plecoglossi and that natural infection in fish seems to occur perorally rather than via the skin.
Journal ArticleDOI

Enhanced Photocurrent in Organic Photoelectric Cells Based on Surface Plasmon Excitations

TL;DR: In this article, surface plasmons (SP) were excited on both of the electrodes of organic photoelectric cells of Al/copper phthalocyanine/Ag structure using attenuated total reflection method to examine the influence of excitation of SP on photoelectric effects.
