DESCRIPTION:Dr. Fabien Sorin\, Saint-Gobin Research 1\nThe ability to mani
 pulate materials in order to tailor and extend their properties to length 
 scales spanning from the nanometer to the kilometer range remains a challe
 nge in both fundamental and applied research. For example\, several applic
 ations in energy harvesting and storage\, health care\, or distributed sen
 sing\, require complex nano-scale devices to be employed over macroscopic 
 systems. This entails a controlled fabrication over drastically different 
 length scales that is still difficult to achieve using conventional proces
 sing approaches. In this talk\, I will present an original approach based 
 on simple thermal drawing processes that enables the fabrication of nano-s
 tructured materials and composites with unprecedented aspect ratios. In pa
 rticular\, I will show how we were able to realize tens-of-meters long and
  flexible polymer fibers that integrate a prescribed assembly of conductin
 g\, semiconducting\, insulating\, and other functional materials into spec
 ific geometries and with micro- and nano-scopic feature sizes. Then\, I wi
 ll introduce the concept of one-dimensional distributed photodetecting dev
 ices and demonstrate how we can utilize the unique interplay between the m
 aterials\, structures\, and length scales of our processing approach to ac
 hieve unprecedented functionalities at the single fiber level as well as i
 n fiber assemblies and fabrics. Finally\, I will present a few examples to
  illustrate the wide range of new fundamental phenomena and potential appl
 ications that will be made possible by the rapidly evolving scientific fie
 ld of multimaterial nano-stuctured fibers and composites.
