About this collection

Guest Edited by Nianjun Yang, University of Siegen, Dai-Wen Pang, Wuhan University, and Yasuaki Einaga, Keio University.

This collection covers the contributions regarding synthesis, properties and applications of various nanocarbon films (e.g., graphene, diamond, diamond-like carbon, carbon nanotubes, fullerenes, etc.), their nanostructures (e.g., graphene/carbon dots, diamond particles, etc.), and their composites. The synthesis approaches of large area and defects-free nanocarbons, characterization of low dimensional fine structures of nanocarbons, surface properties (especially surface chemistry of nanocarbons), as well as their applications in the fields of biomedicine, energy, catalysts, detection, and environment, engineering, and electronics are highlighted.

Moreover, the scope of this issue loosely aligns with an accompanying symposium held at the 2019 Spring E-MRS meeting: Symposium M – Advanced carbon materials: electrochemical aspects, which will be held in Nice, France from 27-31 May 2019.
