The research efforts made to tailor ceramic microstructure so as to improve properties are described in this chapter. Although many material properties are affected by the microstructure, the emphasis here is placed on the mechanical properties, especially strength and fracture toughness. In particular, attention is focused on silicon nitride ceramics, the mechanical properties of vhich have been improved substantially through microstructure tailoring during the past tv o decades. 

A few chosen examples shall illustrate the remarkable physical properties which

The chemical and physical properties of the Chevrel compounds have been covered in books. [228] The enormous interest in these compounds was due to the fact that Mo6SgPb turned out to be a superconductor (7 = 14K), [229] with the highest upper critical fields, 60 Tesla, known at the time.

The structure-property relations of fullerenes, fullerene-derived solids, and carbon nanotubes are reviewed in the context of advanced technologies for carbon-hased materials. The synthesis, structure and electronic properties of fullerene solids are then considered, and modifications to their structure and properties through doping with various charge transfer agents are reviewed. Brief comments are included on potential applications of this unique family of new materials. 

Chapter 1 contains a review of carbon materials, and emphasizes the stmeture and chemical bonding in the various forms of carbon, including the foui" allotropes diamond, graphite, carbynes, and the fullerenes. In addition, amorphous carbon and diamond fihns, carbon nanoparticles, and engineered carbons are discussed. The most recently discovered allotrope of carbon, i.e., the fullerenes, along with carbon nanotubes, are more fully discussed in Chapter 2, where their structure-property relations are reviewed in the context of advanced technologies for carbon based materials. The synthesis, structure, and properties of the fullerenes and...

While there is much to discuss about order in films of different conjugated molecules, a comprehensive survey of the structural properties of various conjugated polymers can be found in Ref. [9]. This section focuses on the relation between microscopic order and macroscopic properties, and on structure-property relations. 

From the optical absorption of two different hexaphenyl films, one with its chains predominantly standing upright on the substrate, the other with the chains randomly distributed in all orientations, similar structure property relations can be concluded [139]. By comparing the calculated absorption coefficient [139J perpendicular to the chains with the observed optical absorption spectra of both films we see that the optical absorption, plotted in Figure 9-9, in the visible and...

The use of AOS and other surfactants as steam-foaming agents has been studied by several oil companies in laboratories and in the field [55-62]. In the next section we will view olefinsulfonate structure-property relations [40] that have helped design optimum surfactants for enhanced oil recovery applications.

Dusek (1), Shy (2 and Bauer (3) give examples of modelling the structure-property relation of several networks (Tg, gel point, etc.). Examples are described of models on solvent evaporation, calculation of functionalities, molecular weight of resins (4), etc. 

In parallel with polymer synthesis, many activities have been directed towards soluble, well-defined oligomers. Aside from purely synthetic considerations, access to oligomers is, important for the optimization of polymer generation and for the understanding of structure/property relations in the class of PPP...
