“…To prepare NTs with encapsulated SnO, they were opened, washed with HNO 3 , placed in a concentrated SnCl 2 solution and then the pH value of the suspension was slowly increased to 10.2 using a solution of Na 2 CO 3 . 73 Encapsulated crystallites were found to have a spherical or ellipsoidal shape and a diameter from 2 to 6 nm.…”

“…The introduction of metals and metal salts inside nanotubes demonstrates the availability of the nanotube interior for interaction with other substances. 3,[7][8][9][10] The curvature of the nanotube interior compared to a plane graphitic sheet is expected to cause enhanced adsorption properties for gaseous species, including hydrogen and the rare gases. Theoretical studies predict an increased adsorption capacity and adsorption binding energy of openended nanotubes.…”

The adsorption of Xe into carbon single walled nanotubes with both closed and open ends has been investigated using temperature programmed desorption and other surface analytical tools. It has been found that opening the ends of the nanotube by chemical cutting increases both the kinetic rate and the saturation capacity of the nanotubes for Xe at 95 K. Further enhancement in Xe adsorption kinetics and capacity are achieved by treating the nanotubes in vacuum at 1073 K where CO, CO 2 , CH 4 , and H 2 are evolved. On this basis it is postulated that surface functionalities such as ϪCOOH block entry ports for adsorption at the nanotube ends and at the defect sites on the walls. The thermal destruction of these functionalities leads to enhanced adsorption. The denser phase of Xe inside the saturated nanotubes desorbs by zero-order kinetics (E d ϭ26.8Ϯ0.6 kJ/mol͒. It is postulated that a quasi-one-dimensional Xe confined phase in equilibrium, with a two-dimensional Xe gas phase on the exterior, provides a phase transition governing the zero-order kinetics desorption process.

This article reviews the phenomena occurring during irradiation of graphitic nanoparticles with high-energy electrons. A brief introduction to the physics of the interaction between energetic electrons and solids is given with particular emphasis on graphitic materials. Irradiation effects are discussed, starting from microscopic mechanisms that lead to structural alterations of the graphite lattice. It is shown how random displacements of the atoms and their subsequent rearrangements eventually lead to topological changes of the nanoparticles. Examples are the formation of carbon onions, morphological changes of carbon nanotubes, or the coalescence of fullerenes or nanotubes under electron irradiation. Irradiation-induced phase transformations in nanoparticles are discussed, e.g. the transformation of graphite to diamond, novel metal-carbon phases in nanocomposite materials or modified phase equilibria in metal crystals encapsulated in graphitic shells.
