Internal stress analysis of a wound roll across widthwise direction
Nihon Kikai Gakkai ronbunshu, 2014 Many kinds of defects occurring at winding process such as telescoping and starring have been recognized. Their main cause is internal stress of a wound roll. Thus, understanding internal stress of a wound roll is necessary to prevent these defects.

Role of the Recombination Zone in Organic Light‐Emitting Devices
Advanced Materials, EarlyView.This review summarizes the critical role of the recombination zone in organic light‐emitting diodes (OLEDs). We highlight that broadening the recombination zone in OLEDs based on emissive layers with balanced charge transport and high photoluminescence quantum yields provides a promising route toward achieving both long operational lifetime and high ...
