Why do we publish papers?I cannot speak for all,but like many others,my students and I publish to report progresses and innovations addressing one or more elements of materials research(e.g.,synthesis and processing,microstructures and characterization,material properties,or performances and applications).Sometimes,it is to disclose a finding and to show a new angle of thinking,to document data and protocols,to share thoughts and solutions of a problem,and sometimes it is to dispute earlier interpretations and to call for *** aspire to share something useful for others and to add as much intellectual value as possible to the scientific literature.

*** Lopez-Salas is a group leader in the Colloid Chemistry Department of the Max Planck Institute of Colloids and Interfaces at Potsdam,Germany,and the lead author of“Rediscovering Forgotten Members of the Graphene Family”,the very first Viewpoint article in Accounts of Materials *** article received strong interest in the materials community,and many are intrigued by the idea of rediscovering old chemistry for creating new materials and want to know the story leading up to this Viewpoint.I(J.H.)recently had the pleasure and quite some fun to ask her(N.L.S)about it.
