The single-crystal X-ray lab is equipped with two diffractometers and a series of devices which allow
to perform in-situ experiment under extreme conditions.

Two 4-circle kappa diffractometers are available: 1) Xcalibur - Oxford Diffraction,  equipped with both
point and CCD detector, and 2) KM4 KUMA equipped with a point detector. This two diffractometers
allow to obtain accurate and precise unit-cell parameters of the crystals under investigation, along
with a good integrated intensity of the Bragg reflections. Driving software and data reduction are
governed by CrysAlis, an all-in-one crystallographic software package.

As we are also interested in experiments under extreme conditions, the laboratory is equipped with
a series of devices and facilities devoted to in-situ high-pressure experiments: ETH-type diamond anvil cells, mini-spectrophotometer for pressure calibration by fluorescence methods, spark eroder and mechanical
micro-driller.

Weissenberg and precession cameras have to be mentioned in order to complete the instrument list.

  
Attività di Ricerca
svolta dal
laboratorio /
Research activities

Attività di Ricerca - Research

Crystallography: Structure analysis

Mineral physics: Equation of State, Elastic properties, Phase stability

The materials under investigation are usually minerals, or their synthetic analogues.
Beyond the mineralogy, the laboratory provided experimental data used in solid-state chemistry,
pharmaceutical, forensic, and archaeological applications.

Didattica svolta dal laboratorio - Teaching

Bachelor, master and PhD students are educated to the use of the diffractometers and of the
high-pressure devices. Courses devoted to the data treatment and structure refinement are provided.
