	abstract = {We present the design and characterization of a compact and portable spectrometer realized for photon in-photon out experiments (in particular X-Ray Emission Spectroscopy, XES), in particular tailored to be used at the FERMI free-electron-laser (FEL) at ELETTRA (Italy). The spectrometer can be installed on different end stations at variable distances from the target area both at synchrotron and FEL beamlines. Different input sections can be accommodated in order to fit the experimental requests, with/without an entrance slit and with/without an additional relay mirror. The design is compact in order to realize a portable instrument within a total footprint of less than one square meter. The instrument is based on the use of two flat-field grazing-incidence gratings and an EUV-enhanced CCD detector to cover the 25-800 eV spectral range, with spectral resolution better than 0.2%. The absolute response of the spectrometer, has been measured in the whole spectral region of operation, allowing calibrated measurements of the photon flux. The characterization on the Gas Phase beamline at ELETTRA Synchrotron as instrument for XES and some experimental data of the FEL emission taken at EIS-TIMEX beamline at FERMI, where the instrument has been used for photon beam diagnostics, are presented.},

	abstract = {Photoelectron spectroscopic measurements have been performed, with synchrotron radiation on PbSe/CdSe heteronanocrystals that initially consist of core-shell structures. The study of the chemical states of the main elements in the nanocrystals shows a reproducible and progressive change in the valence-band and core-level spectra under photon irradiation, whatever the core and shell sizes are. Such chemical modifications are explained in light of transmission electron microscopy observations and reveal a phase transformation of the nanocrystals: The core-shell nanocrystals undergo a morphological change toward a Janus structure with the formation of semidetached PbSe and CdSe clusters. Photoelectron spectroscopy gives new insight into the reorganization of the ligands anchored at the surface of the nanocrystals and the modification of the electronic structure of these heteronanocrystals.},
