报告题目:SAXS : From incoherent to coherent scattering at synchrotron beamlines (NO.PSLAB290-PS2019-05)
报 告 人:Prof. Alain Gibaud
单  位:Le Mans Université, France

 SAXS is a dedicated technique to study the shape and the electron density of particles in solution or as powders. After a brief description of the ID02 and ID10 beam lines at ERSF, I will discuss the advantage of using coherent scattering over incoherent scattering. In particular, I will show the principle of coherent X-ray diffraction. In the second part of this presentation, I will give examples of experiments made at ID02 on calcium carbonate porous particles either in dry condition or during precipitation in a microfluidic device. Finally I will show how CXDI can be used to provide information about the inner and outer 3D morphology of calcium carbonate particles including PCC and marine microorganisms.
