Electrochemical determination of phenothrin in fruit juices at graphene oxide-polypyrrole modified glassy carbon electrode

open access: yesSensing and Bio-Sensing Research, 2018
An electrochemical sensor was developed based on graphen oxide-polypyrrole modified glassy carbon electrode (GO/PPy/GCE) for sensitive determination of phenothrin in fruit samples.

Evaluation of graphen oxide nanoparticles efficacy in chromium and lead removal from aqueous solutions

open access: yesمجله دانشگاه علوم پزشکی بیرجند, 2015
Background and Aim: Currently, several methods are used to remove heavy metals from aqueous solutions one of which is the adsorption process. Graphene oxide nanoparticles, due to their high adsorption capacity, have caused major concerns.

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.

Graphene and graphene oxide for desalination

open access: yesNanoscale, 2016
There is a huge scope for graphene-based materials to be used as membranes for desalination. A very recent study has confirmed that 100% salt rejection can be achieved for commonly used ions by utilizing single layer nonporous graphene. However, the cost effective fabrication procedure for graphene oxide membranes with precise control of pore size can ...
