Graphene oxide nanomaterials are being developed for wide-ranging applications but are associated with potential safety concerns for human health. We conducted a double-blind randomized controlled study to determine how the inhalation of graphene oxide n
of graphene nanomaterials, and graphene circulates through the body of mice in 30 min, accumulating at a working concentration in the liver and bladder [32,50–52]. However, GO derivatives had rather finite intestinal adsorption and were rapidly excreted in adult mice via oral administration [31...
Graphene has attracted intensive research interest in many fields, owing to its remarkable physicochemical properties. Nevertheless, its low dispersibility in most organic solvents and in water, and its tendency to aggregate, prevent full exploitation of its properties. Graphene oxide (GO) is an altern...

Functionalized graphene oxide (GO)/SiO2nanocomposites (FGS) was successfully fabricated by two steps; the first one was the combustion of RHP in covered crucible inside stainless steel autoclave at three different temperature, 400, 500, and 600 °C at 1 h for obtaining ash RHA1, RHA2, and ...
Graphene oxide (single layer graphene oxide, GO) and graphene nanoplatelets (GNP; HDPlas™ GNPs Grade 4) were obtained from Cheap Tubes (Battleboro, 112 Mercury Drive, VT05301, USA; http://www.cheaptubes.com). Carbon black (CB) powder (Printex®85, Evonik-Degussa, Germany) was include...
For instance, a layer of suspended exfoliated graphene located on a trench pattern of silicon oxide/silicon substrate was analyzed with AFM, showing graphene thickness of less than 10 nm, spring constant in the range of 1 to 5 N/m, and Young’s modulus of 0.5 TPa, which is less than ...
The adhesion enhancement of graphene oxide (GO) and reduced graphene oxide (rGO) layer in the underlying polyethersulfone (PES) microfiltration membrane is a crucial step towards developing a high-performance membrane for water purification applications. In the present study, we modified the surface of...
In addition, graphene can be dissolved in solvents or folded. When dissolved, a single layer of graphene oxide can lose as much as 20% of its carboxylic functionality. As a result, this material is highly thermally unstable. In this case, the chemical reaction between thionyl chloride and gra...
An international group of physicists led by the University of Arkansas has created an artificial material with a structure comparable to graphene. "We've basically created the first artificial graphene-like structure with transition metal atoms in place ofcarbon atoms," said Jak Chakhalian, professor...
