Applications in materials science of combining Raman and X-rays at the macro- and micrometric scale

Simultaneous combination of Raman with X-ray Absorption Spectroscopy (XAS) has become of great interest in Materials Science. Four applications are reviewed in this article that reflect the large range of possibilities offered by such coupling at the macro and micrometer scales. Special emphasis was laid on the macrometer scale on time-resolved studies of physico-chemical transformations, either for providing more complete analysis of structural changes or for looking at the sample integrity. The capability of Raman and XAS to provide complementary chemical and structural information was also pointed out for discriminating and characterizing chemical phases in heterogeneous materials at the micrometer scale.
