In situ coherent X-ray diffraction imaging of radiation-induced mass loss in metal-polymer composite spheres

Autor: Dag W. Breiby, Federico Zontone, Eirik Torbjørn Bakken Skjønsfjell, Yuriy Chushkin

Publikováno v: Journal of Synchrotron Radiation

A major limitation to the use of coherent X-ray diffraction imaging (CXDI) for imaging soft materials like polymers and biological tissue is that the radiation can cause extensive damage to the sample under investigation. In this study, CXDI has been
