Cover Picture: Synthesis of a Self‐Assembled Hybrid of Ultrananocrystalline Diamond and Carbon Nanotubes (Adv. Mater. 12/2005)

Abstract The cover shows self‐assembled hybrids of ultrananocrystalline diamond (UNCD) and carbon nanotubes (CNTs). These hybrids were successfully prepared by their simultaneous growth within an argon‐rich Ar/CH₄ plasma, in work reported on p. 1496 by Carlisle and co‐workers. Various methods demonstrated the coexistence of UNCD and CNTs, and the capability of controlling the relative fraction and configuration of UNCD and CNTs in the hybrid material. This new synthesis pathway enables the development of new nanocarbons with unique mechanical, tribological, and electrochemical properties.
