Front Cover: After 14 years of usage, the design of the Macromolecular journals that has been familiar to us since 2007 is being retired for a new generation of Macromolecular journals aesthetics. Starting with this current issue, Macromolecular Theory and Simulations will feature a new, full-page cover picture layout with a consistent Macromolecular logo and title across the journal family.
