SYMPOSIUM 13: Mesoscale phenomena in ceramic materials, nano- and microstructures

EMA2017_650x65

 

Mesoscopic phenomena span length scales that are considerably larger than atomic-bond distances, but small enough that classical continuum physics with materials properties and behavior averaged over many domains, or regions 10–100 nm in size, does not apply. The involved physical processes belong to a region bridging quantum mechanical and macroscopic continuum materials descriptions, which makes them critically important for any multiscale level approach to materials design, modeling, growth and characterization. Furthermore, such phenomena are interesting in their own right, since many materials systems exhibit intriguing behavior with nontrivial dependence on shape, size and geometry that is yet to be fully understood. Specifically, in nonmetallic ceramics, such as, e.g., complex oxides, this may include interactions among elastic, polar and magnetic parameters, as well as the effects of layering, composition variation and ionic diffusion. Simple fundamental examples range from the influence of shape of ferroelectric nanostructure on its domain configuration to fine-tuning the optical response of core-shell nanoparticles to processes of phase separation in multi-component systems. This symposium will bring together experts from academia, industry, and national laboratories to discuss the current state-of-the-art (and future directions) in theoretical modeling, synthesis, characterization and processing of mesoscopic ceramic structures, with a primary focus on the influence of shape, size, geometry and the strength of the involved interactions on the system properties and functional behavior.
