The 1st NATO technology discussion board was once held in Biarritz in September 1990. This Taormina convention is the second one in a chain that we want to be an extended one and that i think that it has equalled the good fortune of its predecessor. In establishing those conferences the NATO technological know-how Committee desired to assemble top specialists to study fields of sturdy current curiosity.

HNO3 , SO3 , HClO4 , and HCOOH) exfoliation due to the formation of gaseous decomposition products is thought to be similar to the case of sulfuric acid. , FeCl3-GICs) by rapid heating is also due to the decomposition of metal chloride to gaseous species. [73] As this reaction is exothermic, these reaction products and also a part of the hydrazine that penetrates into the graphite gallery are vaporized. Using anhydrous hydrazine, the reaction occurs so violently that the temperature of the sample goes up, which further accelerates the exfoliation process.

53] The exfoliated coke particle is shown in Fig. 13. Pores with rather homogeneous size of 30 Â 10 mm are observed. 3). 5. Characterization of Exfoliated Graphite Techniques for the characterization of exfoliated graphite had been limited mainly because of its fragile and macroporous nature. Parameters that had been applied to most carbon materials, such as lattice constants and crystallite sizes determined by XRD and specific surface area by nitrogen adsorption at 77 K, provided only limited information.

The apparent diameter of the exfoliated fiber became more than 10Â the original, about 50– 60 mm. It has to be pointed out that the cross-sectional view of the fiber after exfoliation [Fig. 24(d)] is quite similar to the fractured view of worm-like particles of exfoliated graphite (Fig. 1), Exfoliation of Graphite via Intercalation Compounds 31 suggesting that exfoliation occurs at interlayer spaces of crystallites composed of fibers. From these results, this phenomenon is suggested to be an exfoliation by decomposition of intercalates between the hexagonal carbon layers of crystallites.
