Francesco Carlà – Diamond Light Source (UK)

Abstract

Surface x-ray diffraction (SXRD) is a very powerful tool for the structural characterization of surfaces, interfaces, 2D layers and thin films. Thanks to the use of high brilliance x-ray sources and the high transmission of hard x-rays through dense medium, SXRD can be used as a very versatile probe for investigating chemical reactions and physical processes in a variety of experimental conditions and sample environments ranging from high pressure chemical reactors to liquid cell in physiological conditions and solid state batteries. During the talk different applications of SXRD to the study of different kind of systems will be presented, with a special focus on its use in the field of electrochemistry.
The last part of the presentation will be dedicated to discuss the opportunities offered by the I07 Surface and Interface diffraction beamline. I07 is located at Diamond Light Source (Oxford) and can be accessed by scientists working outside the UK without any restrictions. The beamline is equipped with a multi-purpose diffractometer supporting a variety of sample environments (catalysis reactor, electrochemical cells, Langmuir trough…) and a UHV endstation.
