||Nanocomposites may be viewed as abundant interface nanoscale systems having the ability to manipulate length-scales fundamentally important to many physical properties. Sometimes, this can impart multiple functions, which has led to a rapidly expanding scope and arena of application for these materials. In line with typical composite logic, the function of nanoparticles in a matrix is dependent on: (i) nanoparticle-matrix interaction and (ii) nanoparticle distribution in the matrix. This is with regard to any material property of the nanocomposites, be it crystallographic and/or electronic structure related. This symposium will highlight a broad cross-section of contemporary research on the structure, processing, property, characterization, and modeling aspects of nanocomposite materials, including nanoparticle- and/or nanofiber-based materials. Contributions are solicited in, but not limited to nanocomposites for mechanical, thermal, energetic/catalytic, optical, magnetic, electronic, and biological applications. Submissions that focus on nanocomposites for multi-functional or green-energy applications are especially welcome. Abstracts may be submitted electronically at http://www.tms.org/TMS2015.
