We present three cases of intracorneal pencil graphite particles following penetrating ocular injury. Slit lamp examination revealed pencil graphite particles in the corneal stroma in all cases. Although we did not remove the particles, no complications occurred during the follow-up period. We assumed that removal of the pencil graphite particles was unnecessary, and it was avoided to prevent t...

A solvent-free Diels-Alder reaction was carried out by heating a mixture of graphite and a typical dienophile, maleic anhydride (MA) or maleimide (MI), in a sealed glass ampoule of argon. The functionalization of graphite with dienophiles was confirmed by various characterization techniques, suggesting the efficient functionalization and delamination of graphite into a few layers of graphitic n...

Amorphous Sb2S3 embedded in a conductive graphite matrix is designed for sodium-ion batteries. Owing to the amorphous structure of the active phase and the conductive graphite matrix, the Sb2S3-graphite electrode exhibits a high initial Coulomblic efficiency, a high rate capacity, and stable cycle performance in sodium-ion batteries.

At BNM-LNHB, the references in terms of absorbed dose to water are based on graphite calorimeter measurements. In the cobalt-60 beam, measurements were performed directly with the graphite calorimeter in a graphite phantom. Absorbed dose to water in a water phantom was then determined using a transfer method by means of relative measurements made with ionisation chambers and Fricke dosimeters. ...

Graphenes are an emerging class of carbon nanomaterials whose adsorption properties toward organic compounds have not been well understood. In the present study, graphene nanosheets were prepared by reoxidation and abrupt heating of graphite oxide, which was prepared by sequential chemical oxidation of commercial nonporous graphite powder. Adsorption properties of three aromatic compounds (naph...

Carbon materials such as graphite and graphene exhibit high electrical conductivity. We examined the electrical conductivity of synthetic and natural graphene powders after the chemical reduction of synthetic and natural graphite oxide from synthetic and natural graphite. The trend of electrical conductivity of both graphene (synthetic and natural) was compared with different graphite materials...

In this work we reported a novel graphite doped conductive magnetorheological plastomer (GMRP) with magnetic field dependent electro-conductivity. The conductivity of the GMRPs increased by increasing the content of the graphite particles, while it decreased with the graphite size. When the graphite content reached 15 wt%, the conductivity of GMRPs is approximately 10 000 times higher than the ...

Microstructure in graphite nodules plays a fundamental role in mechanical properties in cast iron. Traditional measures used to study spheroid graphite are nodules density, nodularity, volume fraction and mean size. However, sometimes these parameters do not permit a good characterization of the microstructure since they do not allow the discrimination of different regions. In fact, other measu...

Novel graphite-molybdenum carbide nanocomposites (G-Mo2C) are synthesized by a typical solid state reaction with melamine and MoO3 as precursors under inert atmosphere. The characterization results indicate that G-Mo2C composites are composed of high crystallization and purity of Mo2C and few layers of graphite carbon. Mo2C nanoparticles with sizes ranging from 5 to 50 nm are uniformly supporte...
