The deformation behavior of a compositionally graded metal-ceramic structure has been investigated by numerical and (semi)analytical simulations. Random microstructure models are able to predict the response of an FGM-structure in a more accurate way than the other approaches. The interwoven structure in the middle of the FGM can be accounted for using this modeling strategy. For the extended periodic unit cell models the predicted stress strain response depends strongly on the micro-arrangement of the inclusions. Detailed information on the microfields of the stresses and strains can only be obtained by the extended unit cell models. The incremental Mori-Tanaka method... 

Whereas the majority of dendrimer-based lipophilic-hydrophilic inclusion phenomena discussed thus far results in random guest positioning on a branched framework, ordered interactions in supramolecular assemblies are also of interest. For example, Gonzalez et al. reported the surface modification of poIy(propyl-eneimine)s with cobaltocenium groups that are easily reduced to Co(0). Reaction of the amine termini with I-chlorooarbonylcobaltocenium afforded the metal-terminated dendrimers. The lipophilic, charge-neutral poly-cobaltocenes were rendered H2O soluble via addition of /1-cyclodextrin (36, fi-CD) based on its cylindrical... 

The combination of a sulfonated diphosphine and a randomly methylated (RAME)-(5 CD led to very stable water-soluble Ru NPs that displayed valuable performances in the catalytic hydrogenation of unsaturated substrates with high activities and selectivities compared with those of sulfonated diphosphine-stabilized Ru NPs without any CD (Figure 3.12) [97]. The so-obtained NPs were fully characterized and compared with sulfonated diphosphine-stabilized Ru NPs. NMR investigations indicated the following (1) the strong coordination of the sulfonated diphosphine ligand at the metallic surface (2) in the presence of CD, the formation of an inclusion complex between the sulfonated diphosphine and the CD that...
