Nitrogen Dioxide Sensing Using Multilayer Structure of Reduced Graphene Oxide and α-Fe₂O₃ [PDF]

Sensors, 2021
Multilayers consisting of graphene oxide (GO) and α-Fe2O3 thin layers were deposited on the ceramic substrates by the spray LbL (layer by layer) coating technique. Graphene oxide was prepared from graphite using the modified Hummers method.

The Degree of Oxidation of Graphene Oxide [PDF]

Nanomaterials, 2021
We show that the degree of oxidation of graphene oxide (GO) can be obtained by using a combination of state-of-the-art ab initio computational modeling and X-ray photoemission spectroscopy (XPS). We show that the shift of the XPS C1s peak relative to pristine graphene, ΔEC1s, can be described with high accuracy by ΔEC1s=A(cO−cl)2+E0, where c0 is the ...

GRAPHENE OXIDE AND REDUCED GRAPHENE OXIDE

International Journal for Innovation Education and Research, 2021
To present a possible new alternative for wound treatment, this work evaluated the biological safety and therapeutic efficacy of graphene oxide (GO) and reduced graphene oxide (rGO) nanoparticles (NPs). First, the nanostructures were studied in silico and showed to be able to inhibit the production of some pro-inflammatory cytokines and stimulate the ...
