Characteristics of Graphene/Reduced Graphene Oxide

2020
Graphene, the thinnest two-dimensional material, is extensively explored by interdisciplinary fields of research communities due to the excellent electronic, mechanical, optical and thermal properties. This chapter provides a comprehensive review of the structure, synthesis, properties and applications of graphene/reduced graphene oxide.

Toxicity and transformation of graphene oxide and reduced graphene oxide in bacteria biofilm [PDF]

Science of the Total Environment, 2017
Impact of graphene based material (GNMs) on bacteria biofilm has not been well understood yet. In this study, we compared the impact of graphene oxide (GO) and reduced graphene oxide (rGO) on biofilm formation and development in Luria-Bertani (LB) medium using Escherichia coli and Staphylococcus aureus as models.

SINTESIS GRAPHENE OXIDE DAN REDUCED GRAPHENE OXIDE

PROSIDING SEMINAR NASIONAL FISIKA (E-JOURNAL) SNF2016 UNJ, 2016
Graphene oxide (GO) and reduced graphene oxide (rGO) have been synthesized chemically from graphite powder. Graphite powder was oxidized with strong oxidator agent molekul  to get graphite oxide, this process was called by Hummer’s methode. Graphite oxide was dispersed in water with ultasonic vibrator to exfoliated graphite oxide layers, and ...

Reduced Graphene Oxide Molecular Sensors

Nano Letters, 2008
We demonstrate reduced graphene oxide as the active material for high-performance molecular sensors. Sensors are fabricated from exfoliated graphene oxide platelets that are deposited to form an ultrathin continuous network. These graphene oxide networks are tunably reduced toward graphene by varying the exposure time to a hydrazine hydrate vapor.

Fibers of reduced graphene oxide nanoribbons

Nanotechnology, 2012
Reduced graphene oxide nanoribbon fibers were fabricated by using an electrophoretic self-assembly method without the use of any polymer or surfactant. We report electrical and field emission properties of the fibers as a function of reduction degree.

Adsorption of VOCs on reduced graphene oxide

Journal of Environmental Sciences, 2018
A modified Hummer's method was adopted for the synthesis of graphene oxide (GO) and reduced graphene oxide (rGO). It was revealed that the modified method is effective for the production of GO and rGO from graphite. Transmission electron microscopy (TEM) images of GO and rGO showed a sheet-like morphology.

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 ...
