We report new three-dimensional (3D)-nanostructured MoS2-carbonaceous materials in which MoS2 sheets are intercalated between the graphite layers that possess a multiply repeated graphite/MoS2/graphite structure which prevents the aggregation of MoS2 and diffusion of sulfur from carbonaceous materials, enhancing the cycling stability of Li-ion batteries. We developed an efficient and scalable p...

Reports of graphite pencil lead injuries to the eye are rare. Although graphite is considered to remain inert in the eye, it has been known to cause severe inflammation and damage to ocular structures. We report a case of a 12-year-old girl with intracorneal graphite foreign bodies following a graphite pencil injury.

Pulmonary tuberculosis is relatively frequent in workers exposed to silica or a mixed dust containing silica (Marchand, 1972). This increased susceptibility has been shown in relation to silica itself (Hunter, i962),coal (Rivers, James, Davies & Thompson, 1957) and talc (Siegal, Smith & Grecnburg, 1943). Since graphite too contains a proportion of silica which is about 2 % in the purest commerc...

Graphite oxide has a complex structure that can be modified in many ways to obtain materials for a wide range of applications. It is known that the graphite precursor has an important role in the synthesis of graphite oxide. In the present study, the basal-plane surface of highly annealed pyrolythic graphite (HAPG) was oxidized by Hummers' method and investigated by Raman spectroscopy and atomi...

This paper describes unusual graphite–sulfide deposits in ultramafic rocks from the Serranı́a de Ronda (Spain) and Beni Bousera (Morocco). These deposits occur as veins, stockworks and irregular masses, ranging in size from some centimeters to a few meters in thickness. The primary mineral assemblage mainly consists of Fe–Ni–Cu sulfides (pyrrhotite, pentlandite, chalcopyrite and cubanite), graph...

Abstract Coating design is an efficient strategy to engineer wettability of surfaces and adjustment the functionality necessities in industrial sectors. The current study reveals feasibility functional aluminum/quasicrystalline (Al-QC) composite coatings fabrication by cold spray technology. A commercially available Al-based quasicrystalline powder (Al-Cr-Fe-Cu) was combined with aluminum alloy...

The UK Atomic Energy Authority (UKAEA) is responsible for managing its liabilities for redundant research reactors and other active facilities concerned with the development of the UK nuclear technology programme since 1947. These liabilities include irradiated graphite from a variety of different sources including low irradiation temperature reactor graphite (the Windscale Piles 1 & 2, British...

Although graphite is not a major waste form in LWR reactors it nevertheless represents a verysignificant problem in nuclear plant decommissioning for many of EPRI’s internationalmembers. Graphite is used as a moderator material in many reactor types, particularly the gascooled reactors in UK and France. It is also used for minor components such as fuel elementsleeves. In all the...

The effect of the local electronic modification of the graphite surface on the gas-graphite interaction has been investigated by the molecular beam scattering technique. The angular intensity distributions of He and Ar beams scattered from pristine and defect induced graphite surfaces have been measured at various surface temperatures. From the He scattering results, the cross-section for the H...
