Abstract: In the last decades, we have witnessed an unprecedented surge in high-pressure research that has greatly improved our fundamental understanding of materials under high compression. The X-ray investigation of matter under extreme conditions has become one of the major activities at the ESRF and other 3rd generation synchrotron sources. In particular, the crystallographic and electronic properties of nanostructured materials is a very recent and interest topics as its understanding is extremely important for possible applications. A deep study of the structural properties of oxides and metals with nanometer grain size under extreme pressure conditions will be reported and the effect of nanostructuration will be discussed in detail. We will present the effect of nanostructuration on the stability field of low pressure phases of many oxides and metals.
