In this paper, we demonstrate a new approach for purifying nanodiamonds using an atmospheric-pressure plasma jet. Oxygen gas is continuously dissociated in the plasma jet and generates reactive oxygen, which plays a key role in removing non-diamond carbon, including graphite and amorphous carbon. The purification process was evaluated by UV-Raman (325 nm) and X-ray photoelectron spectroscopy. This...
Over the past two decades, carbon nanomaterials have attracted great interest for their confirmed friction and wear performances as well as important tribological applications. This article gives a comprehensive review of the recent developments of four typical carbon nanomaterials including fullerenes, carbon nanotubes (CNTs), graphene and nanodiamonds in tribology. Firstly, the applications of the...
