Effect of thermal and gold nanoparticles on the optoelectronic properties of graphene oxide [PDF]

open access: yesScientific Reports
In this study, the effects of thermal reduction and gold nanoparticles on the optoelectronic properties of thin graphene oxide films was systematically investigated. Thermal annealing partially reduced graphene oxide to reduced graphene oxide, leading to

The Degree of Oxidation of Graphene Oxide [PDF]

open access: yesNanomaterials, 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 ...

Facile transformation of graphene oxide nanospheres based on AAO template

open access: yesKuwait Journal of Science, 2023
In this paper, a facile one-step drop method is developed to convert reduced graphene oxide into graphene oxide nanoparticles. An aqueous solution of reduced graphene oxide is poured through the pores of anodic aluminum oxide templates to form graphene ...

GRAPHENE OXIDE AND REDUCED GRAPHENE OXIDE

open access: yesInternational 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 ...

The Enzymatic Oxidation of Graphene Oxide [PDF]

open access: yesACS Nano, 2011
Two-dimensional graphitic carbon is a new material with many emerging applications, and studying its chemical properties is an important goal. Here, we reported a new phenomenon--the enzymatic oxidation of a single layer of graphitic carbon by horseradish peroxidase (HRP).

Biocompatibility of Graphene Oxide [PDF]

open access: yesNanoscale Research Letters, 2010
AbstractHerein, we report the effects of graphene oxides on human fibroblast cells and mice with the aim of investigating graphene oxides' biocompatibility. The graphene oxides were prepared by the modified Hummers method and characterized by high-resolution transmission electron microscope and atomic force microscopy.

Oxidation of Graphene on Metals [PDF]

open access: yesThe Journal of Physical Chemistry C, 2010
We use low-energy electron microscopy to investigate how graphene is removed from Ru(0001) and Ir(111) by reaction with oxygen. We find two mechanisms on Ru(0001). At short times, oxygen reacts with carbon monomers on the surrounding Ru surface, decreasing their concentration below the equilibrium value.

Superflexibility of graphene oxide [PDF]

open access: yesProceedings of the National Academy of Sciences, 2016
SignificanceBending of a thin plate simultaneously involves contraction and stretching of matter relative to a neutral plane, and tensile rigidity dictates the ability of a thin platelet to be bent. If graphene or graphene oxide (GO) were actually behaving as thin platelets, they would display high bending rigidity.
