experiments and simulations | We report here on experimental and numerical studies of the influence of
surfactants on mineral gel synthesis. The modification of the gel structure
when the ratios water-precursor and water-surfactant vary is brought to the
fore by fractal dimension measures. A property of {\em polydispersity of the

Determined from Diffraction Experiments | The structure of liquid N-methylformamide (NMF) has been investigated using
synchrotron radiation at 77 and 95 keV. The use of high energy photons has
several advantages, in this case especially the large accessible momentum
transfer range, the low absorption and the direct comparability with neutron
