Nucleation is a core scientific concept that describes the formation of new phases and materials. While classical nucleation theory is applied across wide-ranging fields, nucleation energy landscapes have never been directly measured at the atomic le

Boron-doped diamond (BDD) has become a well-established material in electrochemistry. Yet, many applications of BDD, especially thin films, would greatly benefit from an increase in specific surface area. This paper presents a simple and reproducible
