Comparisons are presented between predictions and experimental data for such phenomena as modulus degradation caused by matrix cracking, fatigu

Biosensing for the 21st Centuryplication in the understanding of the basic physical mechanisms of this system. Some recent experiments are discussed which emphasize the importance of electron-phonon interaction in these compounds, and may identify them as BCS superconductors between the intermediate to strong coupling limits.

At present, there is increased interest in the application of microscopic quantum theory in order to produce a reliable description of phase equilibrium and, in particular, phase diagrams. Here we discuss

Such nanostructured materials can now be synthesized with modulation dimensionalities from zero (clusters) to three (nanophase materials), each with their own particular advantages. These advantages stem from such diverse effects

Frieder Scheller,Florian Schubertm mainly from two facts: i) a large fraction of the total number of atoms lie at the surface and ii) the unfilled electronic bonding of these atoms makes them extremely reactive. In general it is expected that nanostructures should give the link between atomic, surface and bulk matter physico-chemis
