Graphene has attracted intense interest due to its exceptional physical and chemical properties as well as its wide potential applications. For applications of two-dimensional graphene, commercially viable sources are necessary. Liquid-phase exfoliation graphite is one of the most promising economical mothed for the mass production of graphene. A number of methods have been developed to achieve...

In this paper we present the results of GEANT4 simulations of the production of surface muons as a function of energy of the incident protons on a graphite target. A validation of the GEANT4 hadronic physics models has been performed by comparing the results with experimental data from the Lawrence Radiation Laboratory, United States. Considering the ISIS muon target as a reference, simulations...

A study of the fine rnicrostructure of boronated pyrolytic graphite was made utilizing optical and X-ray diffraction techniques. The influence of boron content on the laminar structure, the lattice parameter, the lattice strain, the particle size, and the flexural strength of pyrolytic graphite were studied. Significant changes in the behavior of all investigated parameters were observed in the...

This paper describes a method to duplicate the structural performance of a graphite-reinforced cementitious composite as the mix proportions and constituents of its cementitious matrix are varied. This is accomplished by placing a test specimen constructed using a modified mixture over a reinforcing scheme identical to that of a control standard and then matching the end deflection of these sam...

the voltammetric performance of edge-plane pyrolytic graphite (epg) electrode via adsorptive stripping voltammetry was investigated for study of the electrochemical behavior of omeprazole (omz) in aqueous solution. the results revealed that the oxidation of omz is an irreversible ph-dependent process that proceeds with the transfer of one electron and one proton in an adsorption-controlled mech...

This research study the application of the immobilized TiO2 layer and Cu-TiO2 layer on graphite substrate as a negative electrode or anode for Li-ion battery. The titania layer was produced through chemical bath deposition method, meanwhile Cu particles were deposited electrochemically. A material can be used as an electrode as it has capability to intercalates Li ions into its crystal structur...

This report summarizes the first year's effort to develop more sensitive techniques for detecting and evaluating flaws in graphite. On the basis of preliminary studies, it was concluded that the potential areas of improvement in the state-of-the-art lay both in the interrogative and interpretative aspects of NDT that is in the techniques of introducing the test energy and generating the test si...

The natural Sri Lanka graphite (vein graphite) is widely-used as anode material for lithium-ion batteries (LIBs), due to its high crystallinity and low cost. In this work, graphitic porous carbon (GPC) and high-purity vein graphite (PVG) were prepared from Sri Lanka graphite ore by KOH activation, and high temperature purification, respectively. Furthermore, a lithium-ion capacitor (LIC) is fab...
