Graphene oxide and reduced graphene oxide-based scaffolds in regenerative medicine

International Journal of Pharmaceutics, 2020
There is a vast and rapid increase in the applications of graphene oxide (GO) and reduced graphene oxide (rGO) in the biomedical field, including drug delivery, bio-sensing, and diagnostic tools. Among all the applications, the GO and rGO-based scaffolds are a very promising system that have attracted attention because of their great clinical ...

Nitrogen diffusion in graphene oxide and reduced graphene oxide foils

Vacuum, 2021
Abstract Measurements of nitrogen diffusion coefficient in graphene oxide (GO) and reduced graphene oxide (rGO) have been performed at different temperatures ranging between 21 °C and 101 °C. GO and rGO foils have been prepared as thin foils with 15 μm in thickness, total surface of about 5 cm2 and active diffusion surface of about 20 mm2.

Argon diffusion in graphene oxide and reduced graphene oxide foils

Vacuum, 2022
Measurements of argon diffusion coefficient vs. temperature in graphene oxide (GO) and reduced graphene oxide (rGO) have been performed. GO and rGO foils have been employed with a thickness of 15 μm. GO has been reduced in vacuum at a temperature of 130 ◦C for 30 min.

Adsorption of Polycyclic Aromatic Hydrocarbons on Graphene Oxides and Reduced Graphene Oxides

Chemistry – An Asian Journal, 2013
AbstractGraphene has attracted increasing attention in multidisciplinary studies because of its unique physical and chemical properties. Herein, the adsorption of polycyclic aromatic hydrocarbons (PAHs), such as naphthalene (NAP), anthracene (ANT), and pyrene (PYR), on reduced graphene oxides (rGOs) and graphene oxides (GOs) as a function of pH, humic ...

The composites based on plasticized starch and graphene oxide/reduced graphene oxide

Carbohydrate Polymers, 2013
The graphite was oxidized to prepare graphene oxide (GO), and GO was reduced by glucose to obtain reduced graphene oxide (RGO) sheet. There were abundant and residual oxygen-containing groups on GO and RGO, respectively. Compared to graphite, the GO and RGO sheets appeared flat and transparent, and the aqueous suspensions followed the Lambert-Beer's ...

Spectroscopy and Microscopy of Graphene Oxide and Reduced Graphene Oxide

2015
Graphene oxide (GO) is an important material that provides a scalable approach for obtaining chemically derived graphene. Its optical and electrical properties are largely determined by the presence of oxygen-containing functionalities, which decorate its basal plane.

Influence of graphene oxide and reduced graphene oxide on the activity and conformation of lysozyme

Colloids and Surfaces B: Biointerfaces, 2017
The dramatically different bio-effects of graphene and graphene oxide (GO) have been widely observed in diverse biological systems, which determine the applications and toxicity of graphene materials. To elucidate the mechanism at molecular level, it is urgent to investigate the enzyme-graphene interaction and its consequences.

Comparison of the Catalytic Oxidation Reaction on Graphene Oxide and Reduced Graphene Oxide

The Journal of Physical Chemistry C, 2014
The capacities of graphene oxide (GO) and reduced graphene oxide (rGO) films grown on silicon substrate to cause the aniline to azobenzene oxidation reaction were compared by using Raman spectroscopy, high-resolution photoemission spectroscopy (HRPES), and work function measurements as well as scanning electron microscopy (SEM).

Electronic structure of graphene oxide and reduced graphene oxide monolayers

Applied Physics Letters, 2012
Graphene oxide (GO) monolayers obtained by Langmuir Blodgett route and suitably treated to obtain reduced graphene oxide (RGO) monolayers were studied by photoelectron spectroscopy. Upon reduction of GO to form RGO C1s x-ray photoelectron spectra showed increase in graphitic carbon content, while ultraviolet photoelectron spectra showed increase in ...

Dispersion and Properties of Graphene Oxide and Reduced Graphene Oxide in Nanocomposites

American Society for Composites 2018, 2018
Reducing graphene oxide (GO) is currently seen as one of the most cost effective and scalable methods to produce graphene sheets. This method takes exfoliated graphite in the form of graphene oxide (GO) and reduces it to reduced graphene oxide (rGO). This reduction process recovers the mechanical, thermal, and electrical properties of GO,1 making it ...
