Description

ROCK : Rocking Optics for Chemical Kinetics ROCK time-resolved X-ray

Absorption spectroscopy (XAS) beamline Energy range 4 - 40 keV
The ROCK beamline (ROCK being the acronym for Rocking Optics for Chemical Kinetics)
is devoted to the study of fast kinetic processes in nanomaterials used in
catalysis and batteries. The objective is to contribute to the development of
more efficient catalysts and batteries which should find successful industrial
applications in the field of energy generation and storage in compliance with
the protection of public health and environment. The better knowledge at the
atomic scale of nanomaterials involved in catalysis or energy storage provided
by time-resolved XAS is recognized by the concerned communities as mandatory
for establishing synthesis strategies leading to important breakthroughs in
the production of energy from renewable sources and in the development of
advanced energy storage devices.
