Metals, 2022 Instrumented indentation can be effectively used to investigate the Portevin–Le Chatelier (PLC) effect at small scales. It has been shown that the PLC effect in single crystals may depend on the crystal orientation, yet the underlying mechanism is ...

On the Orientation-Induced Crystallization of Polymers [PDF]
Polymers, 2016 In order to understand orientation-induced crystallization of polymers, we introduced an intermolecular interaction between polymer chains based on quantum mechanics. We therefore considered a pair of perfectly extended chains where the intermolecular interaction is assumed to be based on the hydrogen interaction with a single chain.

Epitaxial growth of CH3NH3PbI3 on rubrene single crystal
APL Materials, 2020 CH3NH3PbI3 perovskite films were grown epitaxially on rubrene single crystals using the laser deposition method for the supply of the source materials (PbI2 and CH3NH3I). An atomically smooth surface with step-and-terrace structures was observed. Several

Orientation and Crystallization in Polyester (II)
Kobunshi Kagaku, 1960 ポリエチレンオキシベンゾエートからつくった無定形無配向の未延伸繊維の連続延伸について研究した。繊維の延伸が二つの過程, すなわち, 分子鎖の弾性的な伸長配列と流動とから成り, 延伸後の繊維の複屈折率, 切断強伸度, ヤング率などが延伸時の張力ときわめて密接な関係を示すことを知った。限界張力 (0.1～0.2g/d) を境にして, 延伸張力と延伸繊維の性質との関係が急変することから, 限界張力以上では急激に結晶化がすすむと考え, 延伸機構を提案した。

ORIENTATION AND SOLVATOCHROMISM OF DYES IN LIQUID CRYSTALS [PDF]
Molecular Crystals and Liquid Crystals, 2003 The orientation and solvatochromism of some dye molecules in a liquid crystal have been investigated. Interactions with the host and the structure of the dye molecule affect the macroscopic alignment of dichroic dye molecules in a liquid crystal. It was observed that some dye molecules show a large bathochromic shift of their absorption maxima in the ...
