DESCRIPTION:Nanostructured films prepared by liquid deposition\n \nDavid G
 rosso\n1 Laboratoire Chimie de la Matière Condensée de Paris\, Group sol
 -gel chemistry and processing\, UMR UPMC-CNRS 7574\, Université Pierre et

 t\, 75231 Paris. david.grosso@upmc.fr\n\nComplex hierarchical nano structu
 res can be achieved when combining chemical advanced bottom-up strategies\
 , such as self-assembly and sol-gel chemistry\, together with liquid solut
 ion processing\, such as dip-coating. It will be demonstrated that dip-coa
 ting is an extremely versatile tool to prepare thin nanostructured and mes
 oporous metal oxide films from liquid solutions and that it has been used 
 for many decades without taking advantage of its whole potentiality. Many 
 types of oxide can be prepared and will thus be mentioned\, but the presen
 t communication will focus mainly on SiO2 (from amorphous to epitaxial alp
 ha-quartz)\, photoactive TiO2\, and on other state-of-the-art nanostructur
 ed thin films. Their interests in optics\, in microelectronic\, in photovo
 ltaic\, in photocatalysis\, in nano fluidics\, or in nano construction wil
 l also be discussed. The usefulness of the ellipsometry analytical techniq
 ues in determining thin films optical properties\, porosity characteristic
 s\, mechanical properties\, photocatalytic activity\, or thermal and chemi
 cal stabilities will also be presented all along the presentation. Finally
 \, we will show that the described “bottom-up” approaches can be combi
 ned with conventional “top-down” technologies\, such as reactive ions 
 etching or optical and nano imprint lithography\, to construct even more c
 omplex morphologies with multi scales features and motifs.\n1)    D. Gr
