arranged. Among them the following types are met: nanotubes, nanop- ticles, nanopowders, nano?bers, nanowires, nanocomposites, etc. At the microscale Microcomposites, such as metal matrix composites (MMCs), ceramic matrix composites (CMCs), alloys or superalloys, s- tered powders, ceramic materials, magnetorheological ?uids (MRFs), etc. At the macroscale Macrocomposites, such as functionally graded ma- rials (FGMs), thin layers or ?lms, thermal or oxidation or wear resistant coatings, multilayered structures, long ?ber composites, etc. At each level of analysis a response of the material to any physical excitation may be observed, measured and analyzed. In the sense of innovation of a material, the changes or new ideas can be introduced on the same scale of control (say, atomic or nano) in order to achieve fundamentally new behavior on the other scale of observation (say, micro or macro). For instance, by replacing some similar atoms in the metal crystal str- ture (e. g. Ti Ti or Al Al), by unlike atoms in the crystal (e. g. Ti Al), wi- out the lattice symmetry of the original material changing, new improved properties and characteristics may be observed in intermetallics at the - cro or macroscale (higher speci?c strength, better creep resistance at elevated temperatures, better corrosion resistance, to mention only some properties observed at the macroscale). Similarly, changing material characteristics at the nanoscale, enables creation of completely new material functionality at micro or macroscales (e. g."

This book provides at first ideas on the answers that neutrons and Synchrotron Radiation could give in innovative materials science and technology. In particular, non-conventional, unusual or innovative neutron and x-ray scattering experiments (from both the scientific and the instrumental point of view) will be described which either have novel applications or provide a new insight into material science and technology. Moreover, a capability of the existing and the enhanced constitutive models and numerical procedures to predict complex behaviour of the novel multifunctional materials is examined.
