Nanocrystalline Membranes The cover image for article number 2100098 by Kyle S. Brinkman and co‐workers, shows enhanced proton transport properties can be achieved by the novel use of the materials’ interface. The combined “interfacial effect” from hydrated layers and “bulk effect” from oxygen vacancies in nanocrystalline perovskite membrane system indicates that the interface can be used as an alternative pathway for proton transport at low temperatures in contrast to the conventional wisdom of interfacial blocking effect observed in the high temperature ionic conductors.
