DESCRIPTION:Speakers: Thomas Sottmann\n\nIn fundamental research scatterin
 g techniques belong to the standard repertoire to study the structure\, co
 mposition and dynamics of manifold samples ranging over of a wide length a
 nd time scale. Especially neutrons\, which are uncharged and excel through
  a much lower energy than Xrays (a millionth)\, are used as probes with wh
 ich researchers study a very wide variety of complex fluids and materials.
  In industry\, however\, the use of scattering techniques in general and n
 eutron scattering in particular is limited. On the one hand\, scattering c
 urves show the samples structure only in the reciprocal space and sometime
 s a complex data analysis is needed to obtain the structural information. 
 On the other hand\, especially neutrons can be used to look inside a big c
 ar engine\, investigate drug delivery\, see how plants uptake water\, get 
 insights into the development of superconductors\, etc.. In this talk the 
 high potential of scattering techniques is presented by means of (1) the n
 anofoam synthesis from colloidal crystals of PS-nanoparticles and (2) the 
 elucidation of the role of confinement in catalysis\, which is the main go
 al of the Collaborative Research Center 1333. (1) deals with the elucidati
 on of the NF-CID procedure [1]\, which enables the preparation of low-cost
  polymeric nanofoams. Dynamic light scattering (DLS)\, scanning electron m
 icroscopy (SEM) and time-resolved SANS are used to characterize the proced
 ure stepby- step [2]. Starting from the synthesis of the polymer nanoparti
 cles\, their packing in form of colloidal crystals\, the subsequent transf
 ormation into a continuous polymer matrix containing supercritical CO2-dro
 plets up to the final expansion leading to the formation of the nanofoam c
 ould be impressively tracked by the combination of scattering and imaging 
 techniques [3]. In (2)\, SAXS and contrast variation SANS was used to stud
 y the adsorption of ionic liquids in micro-/mesoporous silica [4] and the 
 influence of the confinement on the inner-pore segregation of a dioxane/fo
 rmic acid mixture used in Ru-catalyzed formic acid dehydrogenation to yiel
 d CO2 and H2 [5].\n[1] R. Strey\, A. Müller\, Erzeugung nanodisperser Ein
