Cover: In a long copolymer chain such as Pluronic F127,the mass of the two flanked –OH end groups is only about0.3 wt% as compared to that of the whole macromolecule.What can these easily ignored end groups do in thephysical behavior when responding to environmentaltemperature, particularly when the end groups arepartially oxidized? The cover picture shows some signifi-cant impact on molecular arrangements and textures ofthe solution responding to temperature changes. Furtherdetails can be found in the article by C. Zhang* andA. J. Easteal on page 1220.
