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。

Thermoreflectance Detection of Point Defects Resulting from Focused Ion Beam Milling
Advanced Engineering Materials, EarlyView.Focused ion beam (FIB) milling is a common tool for nanoscale material processing, however irradiation damage, redeposition, and contamination can occur. We use several characterization tools to show FIB‐induced effects beyond 1 mm from the milled area.
