Front Cover: A novel pH sensitive shape-memory polymer (SMP) is prepared by cross-linking the β-cyclodextrin modified alginate (β-CD-Alg) and diethylenetriamine modified alginate (DETAAlg). The pH reversible β-CD-DETA inclusion complexes serve as a reversible phase, and the cross-linked alginate chains serve as a fixing phase. The material can be processed into temporary shape as we required at pH 11.5 and recover to its initial shape at pH 7. The polymer has great potential in medical applications as it is biocompatible and biodegradable and the shape transition pH value is close to that of body fluids. Further details can be found in the article by Xiao-Juan Han, Zhen-Qiang Dong, Min-Min Fan, Yan Liu, Jian-Hu li, Yi-Fu Wang, Qi-Juan Yuan, Bang-Jing Li,* and Sheng Zhang* on page 1055.
