Influence of different buffer gases on synthesis of few-layered graphene by arc discharge method

Graphene based metal and metal oxide nanocomposites: synthesis, properties and their applications

“…29 The bottom-up growth of graphene sheets is an alternative to the mechanical exfoliation of the bulk graphite. In bottom-up processes, graphene is synthesized by a variety of methods such as chemical vapor deposition (CVD), 45,46 arc discharge, 47 epitaxial growth on SiC, 48 chemical conversion, 49 reduction of CO, 50 unzipping carbon nanotubes 51,52 and self-assembly of surfactants. 53 The CVD approach to produce graphene relies on dissolving carbon into metal surfaces, such as Ni and Cu that act as catalysts 54,55 and then forcing it to separate by cooling the metal.…”

Synthesis of graphene-like transparent conductive films on dielectric substrates using a modified filtered vacuum arc system

“…Many publications have already been published dealing with the graphene production, using low-current arc evaporation under relatively high pressure. 9 These processes normally produce multilayered graphene-flakes, which can be used, e.g., in dispersions for conductive spayed coatings. The resulting carbon-black-coatings consist of unordered graphene flakes with no particularly optical transmission (due to high thickness), and therefore, they have to be carefully distinguished from our graphene-like films.…”

Label-free human chorionic gonadotropin detection at picogram levels using oriented antibodies bound to graphene screen-printed electrodes

“…46,47 The ratio of I G / I 2D obtained was $0.4, this showing that the graphene is just a few layers thick (less than 5).…”
