CNR at synchrotron radiation sources
Alberto Morgante
CNR-IOM
Trieste
CNR runs:
9 beamlines open to international users at international synchrotron radiation
sources: Elettra (Trieste, Italy) and ESRF (Grenoble France)
In the period 2010-2013:
839 experiments approved by international review committees and carried out
at CNR beamlines
549 publications on international Journals
76 in journals with IF > 6
CNR Institutes: IOM ISM IC
Experimental techniques:
X-ray spectroscopies (absorption, photoemission) to study electronic structure
of nanometerials, of thin films, of molecular complexes, dynamics of electron
transport processes
X-ray absorption and spin-resolved photoemission techniques to study
magnetic properties of materials
X-ray diffraction for structural analysis (proteins, nanomaterials, thin films)
