Alessandro Ricci

Deutsches Elektronen-Synchrotron DESY, Germany

Postdoc in the coherent X-ray scattering group at P10/PETRAIII beamline at Deutsches Elektronen-Synchrotron (DESY) in Germany. He is focused on the use of coherent X-ray to study dynamic processes in complex materials. He got the PhD in Condensed Matter physics at the Physics Department of the University of Rome Sapienza working on critical phenomena and multiscale phase separation in composite and complex materials. During the phD his activity was focused on experimental and analytical methods based on X-ray diffraction techniques. He is specialized on Scanning X-ray nano-diffraction, X-ray single-crystal diffraction, X-ray powder diffraction; but he also performed EXAFS, SAXS, Multiharmonic-Susceptibility measurements (FC and ZFC), circular dichroism and IR spectroscopy. In recent works (published on Nature and Nature Materials) he shown that, using scanning X-ray nano-diffraction, it is possible to map and control the structural and magnetic heterogeneity in inhomogeneous high-temperature cuprates superconductors, at nanoscale. During last five years he also studied the lattice dynamics of several systems, observing i) tetragonal to orthorhombic structural phase transition in the Fe-As based superconductors ii) the nanoscopic phase separation in the recent KFeSe compounds, iii) the mesoscopic phase separation and the anomalous volume isotope effect in AlMgB systems. He applied also X-ray scattering techniques (SAXS) to biological systems, in particular to study metal filling-emptying mechanism in the ferritin protein. He is proposer of more than 20 approved experimental projects in international synchrotron radiation facilities worldwide. Since 2010 he is a member of the Institute of Crystallography at the National Research Council (CNR) where contribute to researches on spatio-temporal complexity in heterogeneous materials.
