Cover: Under cold crystallization, a unique crystalline structure of PLLA, appearing as a metacrystal, is discovered in a PDLA/LMw-PLLA blend. During a heating process, the metacrystal PLLA first partially melts and subsequently repacks directly into the α-crystal PLLA, without going through the less stable α′-form, by a melt-recrystallization mechanism. Further details can be found in the article by L. Chang and E. M. Woo*on page 125.
