The cover depicts a high‐resolution transmission electron image of a graphene quantum dot. Graphene quantum dots exhibit strong photoluminescence in the visible spectral region. This photoluminescence is investigated by A. M. Rao and co‐workers on page 5062, who determine that it stems from their edge states. They can be used in a wide range of applications ranging from biomedical imaging to energy‐related devices. Artwork by Dr. Robert Johnson.
