DESCRIPTION:Prof. Markus Niederberger\, Laboratory for Multifunctional Mat
 erials\, Department of Materials\, ETHZ\nBio: CV of Prof. Niederberger\nNa
 noparticles with varying\, but defined morphologies are the ideal building
  blocks for the bottom-up fabrication of functional materials. They offer 
 a broad range of interesting properties\, which not only depend on the com
 position\, but also on the crystal structure\, the particle size and shape
  and on the surface chemistry. Accordingly\, successful synthesis routes h
 ave to provide full control over all these parameters. However\, the synth
 esis of nanoparticles (typically as powders) is only the first step on the
  way to prepare “real” materials. For most applications the nanopartic
 les have to be assembled and processed into useful geometries\, including 
 2-dimensional arrangements like films or 3-dimensional bodies like composi
 tes\, foams or aerogels. While this approach provides exceptional flexibil
 ity for combining different types of building blocks on the nanoscale\, a 
 great challenge remains to fabricate a material with macroscopic size. The
  talk will cover the synthesis of metal oxide nanoparticles with different
  shapes using nonaqueous sol-gel chemistry. Different strategies will be p
 resented how to assemble and process the nanoparticles into thin films and
  aerogels bridging several orders of length scales. Incorporation of diffe
 rent types of nanoparticles within the final body enables subtle tuning of
  the properties. Selected applications in the field of photoelectrochemica
 l water splitting\, gas sensing and lithium ion batteries will briefly be 
 addressed.
