Description

B.Sc. in Physics and Materials Engineering (1992; FCT/UNL). Ph.D. in Materials Science – Crystalchemistry and Structural Analysis (2006, FCT/UNL). Main scientific interests: Crystallography, Crystal Chemistry and structural analysis of glasses, ceramics, minerals and cultural materials using synchrotron radiation X-ray absorption spectroscopies such as EXAFS and XANES. Laboratory and synchrotron radiation based X-ray fluorescence and X-ray diffraction. Synthesis of complex oxides by chemical and classic sintering processes (perovskites, pyrochlores and superconducting oxides).
