Add to ORKGCombination of SAXS and USAXS measurements provide an extended q-range (0.006-3.0/nm) to study fractal growth of both aging silica gel as well as precursors of zeolite-A. Mass (silica) and surface (zeolite) fractals are obsd. Scanning transmission X-ray microscopy (STXM) proves to be an extremely useful technique to obtain direct images of wet samples in the 0.1-100 m range, confirming the SAXS/USAXS results on even larger length scale
