MCX

Welcome to the MCX beamline!!

The Materials Characterisation by X-ray diffraction (MCX) beamline allows to perform a wide range of non-single crystal diffraction experiments: grazing angle diffraction and reflectivity, residual stress and texture analysis, phase identification and structural studies and kinetic studies. Systems that can be investigated vary from organic and inorganic thin films, to thermally and/or mechanically modified surfaces of mechanic components, to polymers, catalysts and highly disordered materials in the form of films, powders, fibers. In addition to the scientific heritage, a valuable activity will be the support to technology and industrial production, both for specific tasks of non-destructive control and for the development of new products.

Research Highlights

Interaction mediated growth of chitosan and fatty acid binary system at air-water and air-solid interfaces


The interaction of chitosan with bio-membranes is studied by interaction of chitosan with stearic acid in Langmuir monolayers and Langmuir-Blodgett (LB) films. Their structures, as extracted from x-ray reflectivity and AFM, are found strongly dependent on the chitosan mole fraction and the deposition pressure.

Non destructive XRD investigations on grisaille paint layerson stained glass windows

Non destructive and innovative XRD experiments on the MCX beamline allowed us to recognize the alteration products on the grisailles surface and to propose a mechanism for the formation of alteration patinae.

Structure of Sm- and Gd-doped ceria


In this study some still unexplained structural features of RE-doped ceria (RE≡Sm or Gd) are clarified by the use of synchrotron x-ray powder diffraction. Two structural models are proposed:  a fluoritic one, resembling the CeO2 structure at low RE content, and a hybrid one, intermediate between CeO  and cubic RE2O3, at higher RE content.

Looking for potential nuclear waste disposal materials: Thermo-elastic behaviour of CsAlSiO4 (ABW)


The thermo-elastic behaviour of CsAlSiO4 have been investigated up to 1000 °C. The microporous structure shows a remarkably anisotropic expansion and remains stable.
