Before developing on the different materials in more details, general considerations on porous solids and the main methods to characterize nanoporous systems will be introduced. Applications of microporous and mesoporous materials are addressed in Chapter 10. Other important nanomaterials such as sol-gel materials, porous polymers, carbon nanotubes, organic nanotubes, and photonic crystals are treated elsewhere (2, 5, 8-12).

There are many applications for diamonds and related materials, e.g., diamondlike carbon films, and there are potential applications for Fullerenes and carbon nanotubes that have not yet been realised. However, the great majority of engineering carbons, including most of those described in this book, have graphitic microstructures or disordered graphitic microstructures. Also, most engineering carbon materials are derived firom organic precursors by heat-treatment in inert atmospheres (carbonisation). A selection of technically-... 

The fractal-like organization led, therefore, to conductivity measurements at three different scales (1) the macroscopic, mm-size core of nanotube containing material, (2) a large (60 nm) bundle of nanotubes and, (3) a single microbundle, 50 nm in diameter. These measurements, though they do not allow direct insights on the electronic properties of an individual tube give, nevertheless, at a different scale and within certain limits fairly useful information on these properties. 

Carbon nanotubes (CNTs) are a set of materials with different structures and properties. They are among the most important materials of modern nanoscience and nanotechnology field. They combine inorganic, organic, bio-organic, coUoidal, and polymeric chemistry and are chemically inert. They are insoluble in any solvent and their chemistry is in a key position toward interdisciphnary applications, for example, use as supports for catalysts and catalytic membranes [20, 21]. 

Superconductivity has also been discovered in rather exotic materials, including the following Buckminsterfullerene (Cgo) doped with ICI Carbon nanotubes (superconductivity in just one direction) Nickel borocarbides, which contain Ni2 B2 layers alternating with R C sheets, where R is a rare earth element such as Er and organic superconductors that contain planar organic cations and oxoanions. Chemists and physicists continue to study these and other families of superconductors.

AB3 dendritic platform 23 functioned as an efficient carrier for the controlled formation of diphenylalanine nanotubes (Fig. 5.19). First, it prevented the formation of any organized structures when the peptides were attached. Second, the three units of diphenylalanine were rapidly released upon cleavage of the trigger. Finally, the platform allowed control of the release of the end units through a variety of triggering agents.
