The contrast mechanism of ultra-small-angle X-ray scattering imaging is explained based on phase propagation and dynamical diffraction theory. A complementary geometrical analysis is also presented.

A circulating fluid flow cell is described for the in situ ultra-small-angle X-ray scattering study of solution-mediated systems. Results are presented for the real-time formation and growth from homogenous solution of nanocrystalline ceria that reveal new aspects.
