Graphene is a hot area of research because of its unique and remarkable properties. These properties have invoked researchers to use this form of carbon in various potential applications. One of the bottlenecks in developing such application is mass production of graphene. Hummer’s Method is one of the easiest and economical methods to synthesize huge amount of reduced graphene oxide (RGO) shee...

We report on an easy-to-use, successful, and reproducible route to synthesize functionalized graphite oxide (GO) and its conversion to graphene-like materials through chemical or thermal reduction of GO. Graphite oxide containing hydroxyl, epoxy, carbonyl, and carboxyl groups loses mainly hydroxyl and epoxy groups during reduction, whereas carboxyl species remain untouched. The interaction of f...

Graphite is exfoliated into graphene by shearing vortex fluidic films of N-methyl-pyrrolidone (NMP), as a controlled process for preparing oxide free graphene, and for exfoliating the corresponding boron nitride sheets.

Manganese-nickel (Mn-Ni) oxide films were electrodeposited on a graphite sheet in a bath consisting of manganese acetate and nickel chloride, and the structural, morphological, and electrochemical properties of these films were investigated. The electrodeposited Mn-Ni oxide films had porous structures covered with nanofibers. The X-ray diffractometer pattern revealed the presence of separate ma...

Graphite oxide and graphene oxides have been used as solid catalysts for the synthesis of 5,5-dialkyldipyrromethanes and calix[4]pyrroles in organic and aqueous solutions at room temperature.

Boron-doped graphene, synthesized by annealing a mixture of graphite oxide and B2O3, has shown a high conversion efficiency of 6.73% as a counter electrode (CE) for dye-sensitized solar cells, which is better than the Pt CE.

The gas temperature of atomospheric gas in a graphite atomizer was measured during an atomization stage in graphite furnace atomic absorption spectrometry (GF-AAS), by using a two-line method under the assumption of Boltzmann distribution. Iron and nickel were chosen as the probe elements to compare the gas temperatures obtained with different pairs of spectral lines. The atomic absorptions of ...

The oxidation of a carbon anode with air and CO2 occurs during the electrolysis of alumina in Hall-Héroult cells, resulting in a significant overconsumption of carbon and dusting. Boron is well known to decrease the rate of this reaction for graphite. In this work, the application of boron oxide has been investigated to evaluate its inhibition effect on the air oxidation reaction, and to provid...
