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

Activation of order-disorder dynamics in crystalline Buckybowls

Dibenzo[ghi,mno]Fluoranthene, akacorannulene (C₂₀H₁₀), is a peculiar bowl-shaped molecule displaying unusual pentagonal symmetry and building block of the most celebrated Buckminster Fullerene – C₆₀.

Energy Storage : Groundbreaking electrode for potassium ion batteries

A titanium-based potassium-ion battery positive electrode with an extraordinarily high redox potential was structurally characterized by operando X-ray diffraction at MCX.

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.
