Chemically modified graphite is an economical material with promising applications in its own right or as an intermediate in the synthesis of graphene. However, because of its extreme chemical inertness, to date only two methods-oxidation and fluorination-have been found which can modify graphite with high yield and large throughput. Herein, we describe a third chemical approach for the synthes...

We study a model initially proposed to describe a mixture of (CO) 1−x (N 2) x adsorbed on exfoliated graphite. The approach used here is that of mean field theory. The Mean Field equations and the Helmholtz Free Energy are found. Phase diagrams are calculated too, and it is possible to find an analytic expression for the second order phase transition line.

In situ sonic probe exfoliated graphene sheets in the presence of various concentrations of p-phosphonic acid calix[8]arene are effective in removing nitrate from aquatic effluents, with the efficiency increasing for higher ratios of calixarene to graphite. Mild sonication of the nitrate-adsorbed material releases some nitrate ions back to the effluent.

Few layer graphene (FLG) was synthesized by -wave assisted exfoliation of expanded graphite in toluene with an overall yield from c.a. 7% to 20%. A significant difference in the absorption of -waves by the expanded graphite and toluene allowed a rapid heating of the medium. The number of FLG sheets varies from 3 to 12, while the lateral size of the sheets exceeds few ms. The obtained FLG exhibi...

Surfactant exfoliated 2D hexagonal Boron Nitride (2D-hBN) nanosheets are explored as a potential electrochemical sensing platform and evaluated towards the electroanalytical sensing of dopamine (DA) in the presence of the common interferents, ascorbic acid (AA) and uric acid (UA). Surfactant exfoliated 2D-hBN nanosheets (2-4 layers) fabricated using sodium cholate in aqueous media are electrica...

Mechanical energydissipation is important forvibrationdampingandsoundabsorption. Thispaperprovides an analytical model for the interfacial-friction-based viscous behavior of exfoliated graphite, thereby establishing a methodology that may be applied to such behavior of materials in general. This model is in contrast to the conventional bulk viscous deformation model. It can be used to predict t...

Graphite foil (GF) compressed from exfoliated graphite (EG) is a sealing material, which used in nuclear energy and the chemical industry. The preparation of complex process, includes intercalation graphite, water washing, thermal exfoliation pressing intermediate products. conditions significantly influence structure material its physicochemical properties. Thus, aim work was to reveal correla...

A novel approach for bulk synthesis of lithium-intercalated graphene sheets through the reduction of exfoliated graphene oxide in liquid ammonia and lithium metal is reported. It is demonstrated here that as-synthesized lithiated graphite oxide sheets (Li-RGO) can be directly used as an electrode material in lithium batteries. The electrochemical studies on Li-RGO electrodes show a significant ...

Graphite exfoliation has been the main mechanism to produce graphene material and its derivatives, such as oxide (GO) reduced GO (rGO). This study was aimed exfoliate graphite using MnO2 paste in Zinc-Carbon (ZnC) battery wastes via audio sonication X-ray irradiated water. The exfoliated (EG) sample then characterized UV-Vis spectrophotometry, FTIR spectroscopy, XRD, SEM. EG utilized an additiv...
